Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/cli/cmd/debug/ripgrep.ts`:
- Around line 52-64: The rg files call ignores the --query flag; update the
options passed to Ripgrep.Service.files to include the query when present (use
args.query in the object you pass to rg.files) so the service receives the
filter before the Stream pipeline (refer to Ripgrep.Service and the files(...)
call and the args.query/args.glob symbols). Ensure you only set the query field
when args.query is provided so existing behavior is preserved.

In `@packages/opencode/src/patch/index.ts`:
- Around line 337-346: The patch currently strips BOM via Bom.split before
creating unified_diff and newContent (variables unifiedDiff/newContent), which
hides BOM changes that are later applied by joining with fileUpdate.bom; update
the flow to surface BOM transitions explicitly: modify the ApplyPatchFileUpdate
/ ApplyPatchFileChange interfaces to carry a boolean or enum like bom_changed
(and the original/new BOM values), detect BOM differences between
originalContent.bom and next.bom when calling generateUnifiedDiff, include that
BOM change flag in the returned patch payload alongside unified_diff and content
(or else reject updates that introduce a new BOM), and ensure callers use that
flag to either include a BOM line in the diff preview or block silent BOM byte
changes.

In `@packages/opencode/src/session/compaction.ts`:
- Around line 159-181: splitTurn currently allows the preserved tail to begin
mid-turn (e.g., on an assistant/tool message) which breaks turn coherence;
update splitTurn so the candidate start does not begin inside the turn after the
opening user message — either iterate start from input.turn.start (not
turn.start + 1) or explicitly require that input.messages[start] is the original
turn opener (e.g., check the message role/id to ensure it's the user/opening
message) before calling input.estimate and returning a Tail; keep the budget and
estimate logic but skip any start that is not the turn boundary or not a
user/opening message.

In `@packages/opencode/src/session/message-v2.ts`:
- Around line 22-25: The truncateToolOutput helper currently keeps maxChars
characters and then appends a suffix, which can exceed the intended cap; change
truncateToolOutput to first build the suffix string, compute sliceLen =
Math.max(0, (maxChars ?? text.length) - suffix.length), then if text.length <=
(maxChars ?? text.length) return text; otherwise slice text to sliceLen and
compute omitted = text.length - sliceLen and return the sliced text plus the
suffix so the final string never exceeds maxChars; reference the
truncateToolOutput function and its local variables (maxChars, omitted) when
updating.

In `@packages/opencode/src/tool/agent.ts`:
- Around line 23-27: Change the schema for subagent_session_id to validate as a
SessionID brand instead of any string: replace Schema.optional(Schema.String)
for subagent_session_id with Schema.optional(SessionID) (or
Schema.optional(Schema.brand(Schema.String, SessionIDBrand)) if SessionID is
implemented as a brand) while keeping the existing annotation; decode/validate
this field up front (using SessionID) so later resume logic only falls back to
starting a new session when the ID is well-formed but not found, rather than
when it is malformed or typoed.

In `@packages/opencode/src/tool/bash.ts`:
- Around line 425-426: The tool description still interpolates static
Truncate.MAX_LINES / Truncate.MAX_BYTES while run() uses yield* trunc.limits();
update the description to use the actual runtime limits returned by
trunc.limits() (e.g., use the limits.maxLines and limits.maxBytes values or the
computed keep value) so the advertised tool_output.max_lines/max_bytes match the
configured ones; locate where the description/template is built and replace the
static Truncate.MAX_* references with the runtime limits from trunc.limits() (or
pass those values into the description generator) so the model sees the correct
limits.

In `@packages/opencode/src/tool/edit.ts`:
- Around line 35-45: The module-scoped Map locks and lock(filePath) create a
global, never-cleaned registry (locks, Semaphore.makeUnsafe,
AppFileSystem.resolve); move this per-directory/per-project state into an
InstanceState by creating the Map inside InstanceState.make (or using
ScopedCache provided there) so the Map and Semaphores are scoped to the instance
and will be disposed when the InstanceState is cleaned up; update lock(filePath)
to acquire the Map from that InstanceState/ScopedCache instead of the
module-level variable and ensure any Semaphore cleanup/disposal is performed in
the InstanceState teardown.

In `@packages/opencode/src/tool/grep.ts`:
- Around line 67-79: The code currently throws for any result where
result.partial && result.items.length === 0, wrongly treating unreadable-path
partials as an invalid regex; update the branch in the rg.search handling so you
do NOT throw for all partial+empty results — instead only throw when Ripgrep
explicitly signals an invalid-regex (e.g., check for an explicit exit/code or
error from the ripgrep service such as a returned exitCode === 2 or an error
message indicating "invalid regex"); otherwise let partial+empty fall through to
the normal empty return. Locate the condition around rg.search, result.partial,
result.items and params.pattern and replace the unconditional throw with a
guarded check for a distinct invalid-regex indicator from the ripgrep result
before throwing.

In `@packages/opencode/src/tool/read.ts`:
- Around line 27-34: The Parameters schema currently uses Schema.Number for
offset and limit which allows non-integer or non-positive values; update the
schema to require positive integers (e.g., use a custom integer validator or
Schema.Integer if available) and enforce constraints that offset >= 1 and limit
>= 1 (or apply min value for limit default behavior) so fractional or
zero/negative values are rejected; also add the same validation/guard where
offset/limit are parsed/used (the code around the read handling referenced in
the comment) to validate inputs before slicing, referencing the Parameters
object and the offset/limit fields so invalid values are rejected early.

In `@packages/opencode/src/tool/registry.ts`:
- Around line 145-152: The Schema.declare predicate for parameters currently
only returns a boolean from zodParams.safeParse(u).success, so
Schema.decodeUnknownEffect ends up returning the original input and skips Zod's
parsed.data (defaults, transforms, unknown-key stripping); update the predicate
passed to Schema.declare (the one creating parameters) to call
zodParams.safeParse(u) and, on success, return the parsed.data (not just true)
so the declared Schema preserves Zod's decoded/transformed value, and keep the
annotate({ [ZodOverride]: zodParams }) as-is; ensure this change makes
Schema.decodeUnknownEffect surface the parsed data from zodParams rather than
the raw input.

In `@packages/opencode/src/tool/webfetch.ts`:
- Around line 12-20: The timeout field in Parameters currently allows any
number; update the timeout schema so invalid values fail validation (e.g.,
require timeout > 0 and <= 120, and optionally an integer) instead of accepting
0/negative values. Replace Schema.optional(Schema.Number) for the timeout
property with a constrained number schema (use Schema.Number piped through range
checks such as greater-than 0 and less-than-or-equal-to 120, and/or an integer
check if desired), and keep the existing annotation describing the constraint so
requests with out-of-range timeouts are rejected before decoding/network calls;
reference the Parameters export and its timeout property when making the change.

In `@packages/opencode/src/tool/write.ts`:
- Around line 46-52: The current logic (involving Bom.readFile, Bom.split,
params.content, desiredBom, contentOld/contentNew and createTwoFilesPatch →
trimDiff) allows inserting a BOM from params.content without that byte-level
change appearing in the generated diff; fix by either (A) only ever
preserve/insert the original file's BOM (set desiredBom = source.bom) so BOM
insertion can't sneak in, or (B) explicitly include BOM state in the diff by
computing contentOld/contentNew with the BOM byte when desiredBom differs
(prepend U+FEFF to contentOld/contentNew before calling createTwoFilesPatch)
and/or surface a bomChanged flag in the diff metadata so callers see BOM
changes; update the code around desiredBom, contentOld, contentNew and the
creation of diff/trimDiff accordingly.

In `@packages/opencode/test/file/ripgrep.test.ts`:
- Around line 9-10: Replace the ad-hoc run wrapper with the repo-standard
testEffect harness: remove the local run helper that wraps
Effect.provide(Ripgrep.defaultLayer) and Effect.runPromise, and convert tests
that call run(...) into const it = testEffect(...) style, then append
.live(Ripgrep.defaultLayer) (or .live(...) as appropriate) to each test to
provide Ripgrep.defaultLayer at runtime; target usages of the run function and
references to Ripgrep.Service / Ripgrep.defaultLayer and replace them with
testEffect + .live so the test uses the standard runtime/layer setup instead of
an ad-hoc runtime.

In `@packages/opencode/test/tool/agent-rename.test.ts`:
- Around line 72-74: The test uses toBeUndefined() which can pass if task_id
exists but is set to undefined; update the assertion to check key membership on
Parameters.fields instead: verify that (Parameters.fields as Record<string,
unknown>) does NOT haveOwnProperty("task_id") (or use !("task_id" in
(Parameters.fields as any))) so the test fails if task_id is still present (even
with undefined), while keeping the existing check for subagent_session_id
presence.

Outside diff comments:
In `@packages/opencode/src/session/compaction.ts`:
- Around line 236-241: The recent-turn sizing in SessionCompaction.estimate
currently serializes messages with MessageV2.toModelMessagesEffect(...) but does
not apply the same media-stripping and tool-output truncation that
processCompaction() uses, causing overestimates; update estimate() to serialize
messages using the identical transformation used by processCompaction (i.e.,
apply the same media stripping and tool-output truncation logic or call the
shared serializer/transform function before Token.estimate) so select() budgets
match actual compacted size, and apply the same change to the other occurrence
around lines 405–408.

In `@packages/opencode/src/tool/edit.ts`:
- Around line 89-109: The branch handling params.oldString === "" builds diff
from contentNew before running format.file() so the metadata/diff can mismatch
the final on-disk contents; after writing and calling format.file() /
Bom.syncFile() recompute diff = trimDiff(createTwoFilesPatch(filePath, filePath,
contentOld, contentNew)) (using the possibly-updated contentNew from
Bom.syncFile) and update the metadata passed to ctx.ask (and any snapshot/diff
variables) so the permission prompt and saved diff reflect the formatted file.
Refer to symbols: params.oldString, contentOld, contentNew, diff,
createTwoFilesPatch, trimDiff, format.file, Bom.syncFile, ctx.ask, and
afs.writeWithDirs.

Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/question/index.ts`:
- Around line 54-61: The options array validation must reject duplicate
option.label values (after trimming) so serialized replies aren’t ambiguous;
update the Schema.mutable(Schema.Array(Option)) validation for options to add a
check that maps each option's label (e.g., Option.label) through trim(), ensures
no empty labels, and that the set size equals the array length (reject
duplicates), returning a clear error message like "Option labels must be unique
(after trimming)". Implement this as an additional .check(...) on the same
options schema, referencing the options array and Option.label for
identification.

In `@packages/opencode/src/session/overflow.ts`:
- Around line 17-18: The code uses a fallback with || when computing cap which
treats 0 as absent; in the function in overflow.ts replace the fallback
expression that sets cap (currently using input.model.limit.input || context)
with nullish coalescing so that explicit 0 is preserved (use
input.model.limit.input ?? context), keeping the rest of the calculation
(Math.max(0, cap - reserved)) unchanged; target the cap binding and the use of
input.model.limit.input, context, and reserved when making the change.

In `@packages/opencode/src/tool/tool.ts`:
- Around line 34-42: The Def interface currently loses the tool-specific
metadata generic because execute(args, ctx: Context) does not carry M; change
the execute signature to execute(args: Schema.Schema.Type<Parameters>, ctx:
Context<M>) so the Context preserves the M generic, and make the Context type
generic (e.g., Context<M extends Metadata = Metadata>) with its metadata(...)
method typed to accept M; update any callers/implementations of Def.execute and
the Context definition to use the new generic to ensure the ExecuteResult<M> and
ctx.metadata types are checked against the same M.
- Around line 8-10: The Metadata type currently leaks `any` via the index
signature; change the declaration for Metadata to use unknown instead (e.g.,
make it a Record<string, unknown> or an interface extending Record<string,
unknown>) so consumers don't get implicit anys, and update any places that rely
on framework-owned fields (e.g., `truncated`) to explicitly narrow or assert
those fields where they are consumed rather than widening Metadata itself;
locate the Metadata symbol in tool.ts and replace the `[key: string]: any`
signature accordingly and add explicit type guards/casts at call sites that need
framework-owned keys.
- Around line 77-128: The wrap helper currently builds effects with Effect.gen;
change its constructor to Effect.fnUntraced to match tracing conventions
(replace the Effect.gen wrapper around the closure returned by wrap and ensure
any inner .pipe() operators are passed as extra arguments to Effect.fnUntraced
rather than using outer .pipe()). Also update the exported define and init
functions to use Effect.fn("Tool.define") and Effect.fn("Tool.init")
respectively (give them the named tracing span and move any pipeable operators
into their Effect.fn call), keeping the same behavior for decode, execute,
truncate, and agents usage; reference the wrap function and the exported
define/init functions when locating the changes.

In `@packages/opencode/test/file/ripgrep.test.ts`:
- Around line 172-175: The test hardcodes "/tmp/nonexistent-dir-12345"; replace
that with a platform-neutral temporary path by calling the tmpdir fixture to get
a fresh temp directory and constructing a guaranteed-nonexistent child path
(e.g., path.join(tmpdir(), "nonexistent-"+Date.now() or random suffix)) and pass
that to Ripgrep.Service.use -> rg.files({ cwd: ... }).keep using
Stream.runCollect and Effect.provide(Ripgrep.defaultLayer) /
Effect.runPromiseExit so the test is deterministic and cross-platform; use the
tmpdir helper from fixture/fixture.ts to obtain the base temp directory.

In `@packages/opencode/test/tool/tool-define.test.ts`:
- Around line 2-9: Replace the ad-hoc ManagedRuntime.make usage with the repo
test harness: remove ManagedRuntime.make(...) and instead wrap the test(s) with
testEffect(...) (import testEffect from "test/lib/effect.ts") and pass the
merged layers (Truncate.defaultLayer and Agent.defaultLayer) as the
environment/layers for testEffect; update any direct uses of the runtime
variable to rely on the Effect test callback provided by testEffect and keep
references to the same Layer.mergeAll(Truncate.defaultLayer, Agent.defaultLayer)
so the Agent and Truncate services are available to the tests.

Outside diff comments:
In `@packages/opencode/src/format/index.ts`:
- Around line 120-157: The loop currently sets ran = true before checking the
formatter process result so failed runs still mark success; change the logic in
the for loop that iterates over formatters (the block using formatters, cmd,
spawner.spawn and the code variable) to only set ran = true after verifying the
spawned process exit code is 0 (i.e., after the code variable is checked and
confirmed successful), leaving error logging (log.error) and the existing spawn
catch behavior intact so ran reflects at least one successful formatter run.

In `@packages/opencode/src/question/index.ts`:
- Around line 226-243: The reply handler (Effect.fn "Question.reply") must
validate incoming answers against the stored pending question before publishing
Event.Replied or calling Deferred.succeed: check existing.info.question (or
existing.info.options/metadata) to ensure the number of answer rows matches the
question's expected answerCount, that single-select questions have at most one
selected label, and that every label/value in input.answers exists in the
question's defined choices; if validation fails, do NOT call
bus.publish(Event.Replied) or Deferred.succeed — instead log.warn with details
and call Deferred.fail(existing.deferred, new Error(...)) (or otherwise mark the
deferred as rejected) so callers receive an error; only after passing these
checks, map answers and proceed with yield* bus.publish(Event.Replied, ...) and
yield* Deferred.succeed(existing.deferred, input.answers).

In `@packages/opencode/src/session/compaction.ts`:
- Around line 236-241: The estimate function (SessionCompaction.estimate)
currently serializes full tool outputs via MessageV2.toModelMessagesEffect
before Token.estimate, causing overestimates; update the call to
MessageV2.toModelMessagesEffect (used inside estimate) to pass the same
serialization/compaction options used by the actual compaction logic (e.g., {
stripMedia: true, toolOutputMaxChars: 2000 }) so Token.estimate receives the
stripped/limited message representation and produces a matching size estimate.

In `@packages/opencode/src/skill/discovery.ts`:
- Around line 38-40: The early cache existence checks in Discovery.download (the
Effect.fn "Discovery.download" generator) currently call
fs.exists(dest).pipe(Effect.orDie) which hard-fails on transient FS errors;
change both occurrences to use the safe probe (fs.existsSafe(dest)) or an
equivalent try/catch fallback that treats errors as "not present" and returns
false so the download flow preserves its graceful error handling for HTTP/write
failures; update the two spots that call fs.exists(...).pipe(Effect.orDie) to
call fs.existsSafe(...) (or wrap fs.exists in an Effect that maps failures to
false) and ensure the rest of the generator logic remains unchanged.
- Around line 55-105: The pull() function uses the incoming url directly
(variables url, base, host) which allows SSRF; before constructing index or
fetching, parse the input with new URL(url) and validate that protocol is http
or https, then reject hosts that are loopback or in private/link-local ranges
(e.g., 127.0.0.0/8, ::1, localhost, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16,
169.254.0.0/16) — if the hostname resolves to a private IP also treat as invalid
— log a warning via log.warn and return [] (or throw a controlled error) instead
of proceeding to build index or calling HttpClientRequest.get; add this
validation at the top of Effect.fn("Discovery.pull") so index, host and
subsequent downloads never run for disallowed destinations.

In `@packages/opencode/src/tool/bash.ts`:
- Around line 596-598: The current guard in the timeout validation only rejects
negatives but allows timeout = 0 which becomes an unintended ~100ms timeout when
run() races with Effect.sleep(input.timeout + 100); update the check on
params.timeout to reject non-positive values (use params.timeout <= 0) and
change the thrown message to state "Timeout must be greater than 0" (or
alternatively, if zero should be allowed, document that behavior and adjust the
race logic in run()/Effect.sleep accordingly); reference params.timeout, run(),
and Effect.sleep when making the change.

In `@packages/opencode/src/tool/edit.ts`:
- Around line 89-115: When params.oldString === "" ensure you check whether
filePath is a directory before calling Bom.readFile: use the filesystem helper
(e.g., afs.isDirectory or afs.stat) immediately after existsSafe(filePath) and
if it is a directory return the same explicit "Path is a directory" error used
elsewhere instead of proceeding to Bom.readFile/overwrite; this avoids turning a
user mistake into an internal failure in the create/overwrite path (references:
params.oldString, afs.existsSafe, afs.isDirectory/afs.stat, Bom.readFile,
Bom.join, format.file, Bom.syncFile).

Duplicate comments:
In `@packages/opencode/src/session/compaction.ts`:
- Around line 167-179: The loop may pick a start index that points into the
middle of a turn (e.g., an assistant/tool message) so the preserved tail can
lose its initiating user prompt; instead only consider starts that are turn
boundaries (user message boundaries). Change the selection so for each candidate
start you advance it to the next turn-start/user-message (use the existing
splitTurn or check message.role === 'user' on input.messages) before calling
input.estimate and before returning; ensure you return that adjusted start and
its id from input.messages so the retained tail always begins at a user/turn
boundary.

In `@packages/opencode/src/session/message-v2.ts`:
- Around line 22-25: The truncateToolOutput function currently keeps maxChars
from text then appends the omission suffix, which can exceed the intended
compaction budget; update truncateToolOutput so it first computes the
omissionSuffix string and its length, then if maxChars is provided compute
allowedTextLen = Math.max(0, maxChars - omissionSuffix.length) and slice text to
allowedTextLen before appending the omissionSuffix (handle the case where
maxChars <= omissionSuffix.length by returning only the suffix or an
appropriately short value). Ensure you still compute omitted correctly based on
the original text length and reference the function name truncateToolOutput and
the omitted/suffix logic when making changes.

In `@packages/opencode/src/tool/bash.ts`:
- Around line 584-589: The description string is using the static
Truncate.MAX_LINES and Truncate.MAX_BYTES constants, but run() actually honors
the configured truncation via trunc.limits(); update the interpolation so the
description reports the active limits (call or use the result of trunc.limits()
/ yield* trunc.limits() used by run()) instead of Truncate.MAX_LINES /
Truncate.MAX_BYTES. Locate the code that constructs description (uses
DESCRIPTION.replaceAll(...)) in bash.ts and replace references to
Truncate.MAX_LINES and Truncate.MAX_BYTES with the actual maxLines/maxBytes
values returned by trunc.limits() (or the variable the run() flow already
obtains) so the advertised output window matches the configured tool_output
limits.

In `@packages/opencode/src/tool/grep.ts`:
- Around line 74-79: The current branch throws on any empty partial result
(using result.partial and params.pattern) which wrongly treats
inaccessible/skipped-path partials as an invalid-regex; change the condition so
we only throw when ripgrep explicitly indicates an invalid pattern (e.g., an
exit code of 2 or an error message from the ripgrep output that names an invalid
regex), otherwise return the normal empty/partial result. Update the check
around result.partial && result.items.length === 0 to inspect the
ripgrep-specific error/exit metadata (rather than blanket partial) in the
grep/search handling code so skipped/unreadable-path partials still return empty
without throwing.

In `@packages/opencode/src/tool/registry.ts`:
- Around line 145-152: The current wrapper only checks
zodParams.safeParse(...).success so parsed transforms/defaults are lost; modify
the wrapper around zodParams and the call site before def.execute to actually
parse and pass the Zod-decoded value: have Schema.declare use
zodParams.safeParse to both validate and obtain the parsed value (or call
zodParams.parse) and ensure the value passed into def.execute is the
parsed/normalized result (keep the ZodOverride annotation on parameters with
zodParams). Update references to zodParams/parameters and the def.execute
invocation to use the decoded output instead of the raw input.

In `@packages/opencode/src/tool/write.ts`:
- Around line 48-53: The current diff uses BOM-stripped text
(contentOld/contentNew) so a change in desiredBom (variable desiredBom) can be
missed; update the diff generation before calling createTwoFilesPatch/trimDiff
to account for BOM transitions by constructing the compared strings with the BOM
when present (e.g., prefix contentOld/contentNew with the BOM char when
source.bom/next.bom differ from false) or otherwise inject a small visible
marker when desiredBom !== source.bom; ensure the code paths around
createTwoFilesPatch(filepath, filepath, contentOld, contentNew) and the ctx.ask
call reflect that BOM-aware content so byte-level BOM changes are surfaced in
the produced diff.

In `@packages/opencode/test/tool/agent-rename.test.ts`:
- Around line 72-74: The test currently uses toBeUndefined() to check that
task_id was removed which can be a false positive if the key exists with an
undefined value; replace that assertion with an explicit key-membership check
against Parameters.fields (e.g., use
Object.prototype.hasOwnProperty.call(Parameters.fields, 'task_id') and expect
that to be false) so you verify the key is absent; locate the assertions
referencing Parameters and its fields, in particular the checks for
subagent_session_id and task_id, and change the task_id assertion to assert
non-membership rather than undefined value.

Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/file/ripgrep.ts`:
- Around line 303-320: The code downloads ripgrep into archive and immediately
writes and extracts it without integrity checks; update the download flow around
HttpClientRequest.get / bytes / archive / extract so you verify a pinned
checksum or signature for the downloaded bytes before calling fs.writeWithDirs
or extract: fetch or embed the expected checksum (e.g., alongside url or from a
trusted source), compute a secure hash (SHA-256) of bytes, compare it to the
expected value, and if it does not match fail the Effect with a clear error (do
not write or extract); only proceed to fs.writeWithDirs(archive, ...) and
extract(archive, config, target) after the checksum/signature verification
passes.
- Around line 326-335: The check() helper currently uses Effect.orDie on
fs.isDir(cwd), which turns real filesystem errors into defects; change check()
so it does not call orDie: call yield* fs.isDir(cwd) directly and if it returns
true return, otherwise yield* Effect.fail(...) to synthesize the ENOENT Error;
let any thrown filesystem errors from fs.isDir propagate normally instead of
being converted to defects (reference the check function and fs.isDir call to
locate the change).

In `@packages/opencode/src/format/index.ts`:
- Around line 116-123: The loop over formatters contains a redundant guard "if
(cmd === false) continue" because formatters is produced from getFormatter/get
checks already filtered for truthy cmd; remove that conditional from the for
(const { item, cmd } of formatters) loop (in the function where formatters is
set and iterated) so the loop only sets ran = true and executes formatting logic
for each entry; ensure no other code relies on cmd being false inside that loop.

In `@packages/opencode/src/session/compaction.ts`:
- Around line 159-181: The helper splitTurn currently returns a raw Effect.gen;
wrap it with Effect.fnUntraced so it follows tracing conventions and can accept
pipeable operators. Replace the current return of Effect.gen(...) in function
splitTurn with return Effect.fnUntraced(() => Effect.gen(function* () { ... }))
keeping the same generator body and the Tail/return shape (including references
to input.estimate, input.messages, input.turn, and budget) so behavior is
unchanged but the effect is untraced and pipe-friendly.

In `@packages/opencode/src/tool/grep.ts`:
- Around line 31-32: The execute function is hardcoded to an old arg shape
instead of deriving its type from the Parameters schema; update the execute
parameter typing so it uses the schema's Type (e.g. Schema.Schema.Type<typeof
Parameters> or a local alias like ParametersType) rather than the inline {
pattern: string; path?: string; include?: string } object, and ensure any needed
Schema import is present so execute(params: ParametersType, ctx: Tool.Context)
stays in sync with the Parameters schema (refer to Parameters and execute in
Tool.define).

In `@packages/opencode/src/tool/lsp.ts`:
- Around line 42-45: The execute handler's arg type is manually declared and can
drift from the runtime-decoded shape; replace the ad-hoc args type with the
schema-derived type to keep it in sync by using Schema.Schema.Type<typeof
Parameters> for the input parameter (i.e. change the first parameter of execute
from the current object shape to Schema.Schema.Type<typeof Parameters>), keeping
the ctx parameter as Tool.Context and leaving references to
operations/filePath/line/character intact so the implementation compiles against
the decoded schema.

In `@packages/opencode/test/file/ripgrep.test.ts`:
- Around line 83-97: The test "search returns matched rows with glob filter"
currently writes "needle" only to match.ts so it still passes if globbing is
ignored; change the setup to also write "needle" into the non-*.ts file (the
Bun.write call that creates "skip.txt"), then keep using Ripgrep.Service.use(rg
=> rg.search({ cwd: tmp.path, pattern: "needle", glob: ["*.ts"] })) and add an
explicit assertion that the skipped file is not returned (e.g., assert
result.items length is 1 and that none of result.items paths contain "skip.txt")
so the test will fail if the glob filter is ignored.
- Around line 179-212: The worker-mode test is a duplicate of the direct-mode
test; change the "ignores RIPGREP_CONFIG_PATH in worker mode" case to actually
exercise the worker-backed service instead of the direct service by invoking the
worker-specific entrypoint rather than Ripgrep.Service.use (which the first test
already covers). Locate the test that calls Ripgrep.Service.use and replace the
call with the service's worker API (for example Ripgrep.Service.useWorker,
Ripgrep.Service.spawnWorker, or passing a { worker: true } / { mode: "worker" }
option to the service/run helper depending on the codebase) so that rg.search is
executed through a real worker path, then keep the same setup and assertions
(expect(result.items).toHaveLength(1)).

In `@packages/opencode/test/tool/grep.test.ts`:
- Around line 16-22: Replace the manual ManagedRuntime setup that uses
Layer.mergeAll(CrossSpawnSpawner.defaultLayer, AppFileSystem.defaultLayer,
Truncate.defaultLayer, Agent.defaultLayer, Ripgrep.defaultLayer) with the
testEffect harness: create const it = testEffect(Layer.mergeAll(...)), then
convert each test to it.live("name", () => provideTmpdirInstance((dir) =>
Effect.gen(function*() { ... }))) and inside the generator yield services
directly via yield* Service.<serviceName> (matching existing usage for
CrossSpawnSpawner, AppFileSystem, Truncate, Agent, Ripgrep); ensure tests use
the fixture helpers and Effect.gen pattern instead of ManagedRuntime.

Outside diff comments:
In `@packages/opencode/src/tool/write.ts`:
- Around line 52-66: The prompt currently builds the diff from
contentOld/contentNew before formatting and BOM sync, so users may approve stale
bytes; change the flow so the diff shown to ctx.ask reflects the final bytes
that will be written: either run the formatter on contentNew in-memory (or
write+format+read back) and apply Bom.syncFile to that formatted content, then
compute trimDiff(createTwoFilesPatch(...)) from contentOld and the
post-format/post-BOM content; update the use of trimDiff/createTwoFilesPatch and
the metadata.diff passed to ctx.ask accordingly, and only then call
fs.writeWithDirs and the existing format.file/Bom.syncFile steps (or skip
repeated rewrites if you already produced the final bytes in memory).

Duplicate comments:
In `@packages/opencode/src/tool/tool.ts`:
- Around line 77-128: Replace the raw Effect.gen usages with the repo-standard
Effect.fn* variants: change wrap to return Effect.fnUntraced(...) instead of
Effect.gen, and change the exported constructors define and init to use
Effect.fn("Domain.define") / Effect.fn("Domain.init") respectively; inside wrap,
remove the .pipe(...) call patterns (e.g.,
decode(args).pipe(Effect.mapError(...)) and the final .pipe(Effect.orDie,
Effect.withSpan(...))) and instead pass those pipeable operators as extra
arguments to Effect.fnUntraced so the operators run inside the effect (preserve
the computed attrs for withSpan), keeping the same error-mapping and span
attributes behavior and leaving function names/identifiers (wrap, define, init,
toolInfo.execute, decode) intact.

Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/question/index.ts`:
- Around line 250-295: The reply validation currently allows empty arrays—add a
check in the reply() loop (where you iterate questions with q and answer from
input.answers) to reject answer.length === 0: log a warning (include requestID
and index), pending.delete(input.requestID), and yield*
Deferred.fail(existing.deferred, new RejectedError()); enforce this for both
single-select (q.multiple === false) and multi-select questions so no empty
answers can resolve the deferred.

In `@packages/opencode/src/tool/edit.ts`:
- Around line 130-132: The current Effect.catch around afs.stat(filePath)
swallows all errors and maps them to “not found”; change it so only the
filesystem NotFound case is turned into undefined while other errors are
rethrown. Replace the generic Effect.catch(...) used with afs.stat(filePath)
with a conditional catch that checks the error type/code (the NotFound
predicate) and returns Effect.succeed(undefined) only for that case, otherwise
re-raise the error (e.g., Effect.fail(err)); keep the subsequent checks on the
info variable and the existing error messages for missing vs directory.

In `@packages/opencode/src/tool/question.ts`:
- Around line 6-16: Add a focused test that restores direct coverage for the
migrated question schema by exercising the Parameters struct and the
Question.Prompt contract: write tests that validate accepted inputs of 1 and 4
questions succeed and rejected inputs of 0 and 5 questions fail with the proper
min/max error messages, and also include at least one negative test asserting an
invalid prompt shape is rejected (e.g., missing required fields on
Question.Prompt). Locate and call the Parameters validator (exported as
Parameters) and the Question.Prompt shape from the diff to perform validations
and assert the error messages match the Schema.isMinLength/Schema.isMaxLength
checks and the prompt-shape contract.

In `@packages/opencode/src/tool/truncate.ts`:
- Around line 76-83: The current Truncate.limits implementation swallows
Config.Service read errors by catching them and returning undefined, making real
config failures indistinguishable from no config; update the Effect pipeline so
that when configSvc (from Option via Effect.serviceOption(Config.Service)) is
Some, you do not catch errors from configSvc.value.get(), but instead let the
Effect fail (or explicitly log and rethrow) so callers can detect/read the
failure; only fall back to MAX_LINES/MAX_BYTES when Option.isNone(configSvc)
(service absent). Specifically, modify the Effect inside
Effect.fn("Truncate.limits") to remove or change the Effect.catch(() =>
Effect.succeed(undefined)) around configSvc.value.get(), and handle errors by
propagating them (or logging via the appropriate logger then rethrowing) while
still using MAX_LINES/MAX_BYTES only when the service is missing.

In `@packages/opencode/src/tool/write.ts`:
- Around line 57-72: The current flow calls ctx.ask() with a diff from
contentOld -> contentNew before format.file() may mutate the bytes, so change
the sequence: first write contentNew to disk with fs.writeWithDirs, run
format.file(filepath), then read back the actual bytes (finalContent), recompute
the diff with createTwoFilesPatch(filepath, filepath, contentOld, finalContent)
and trimDiff, and only then call yield* ctx.ask(...) with the recomputed diff
and same metadata (include filepath and bomChanged/desiredBom flags). After
approval call Bom.syncFile(fs, filepath, desiredBom) as before. Ensure you
reference ctx.ask, createTwoFilesPatch, trimDiff, fs.writeWithDirs, format.file,
Bom.syncFile, contentOld, contentNew, finalContent and filepath when making the
change.

In `@packages/opencode/src/util/effect-zod.ts`:
- Around line 61-62: toJsonSchema currently always re-walks the AST via
zod(schema) which ignores any pre-existing Zod surface attached as schema.zod;
update toJsonSchema to prefer and use schema.zod when present (e.g., const
zodSchema = (schema as any).zod ?? zod(schema)) and pass that zodSchema into
z.toJSONSchema so the emitted JSON Schema matches any hand-authored or wrapped
Zod validator; touch the toJsonSchema function and references to
zod(schema)/z.toJSONSchema accordingly.

Duplicate comments:
In `@packages/opencode/src/file/ripgrep.ts`:
- Around line 334-342: The check function currently uses
fs.isDir(cwd).pipe(Effect.orDie) which converts real filesystem errors into
defects; change check (the Effect.fnUntraced named check) to remove the
.pipe(Effect.orDie) and instead handle the effectful result so that
permission/IO errors are returned as failures (PlatformError | Error) — i.e.,
run fs.isDir(cwd) directly, map its boolean success path to returning void, and
map failure cases to Effect.fail with the same enriched Error object (preserving
code/errno/path) so callers like files, search, and tree can surface real
filesystem errors instead of defects.
- Around line 311-328: The download-and-extract flow for ripgrep (symbols:
VERSION, filename, url, archive, HttpClientRequest.get, fs.writeWithDirs,
extract, Global.Path.bin) lacks integrity/authenticity checks; before writing or
extracting, fetch the expected checksum or signature from a trusted source
(release metadata or bundled public key), compute the downloaded bytes' digest
(e.g., SHA-256) or verify the detached GPG signature against the ripgrep release
asset, compare them, and if the verification fails call Effect.fail with a clear
error instead of proceeding to fs.writeWithDirs/extract; ensure the verification
happens immediately after receiving bytes and before caching or extraction.

In `@packages/opencode/src/question/index.ts`:
- Around line 204-227: The uniqueness check is running against raw
input.questions so labels like "A" and " A " bypass it but later collapse when
decoding with Schema.decodeUnknownSync(Request); update the pre-publish guard to
normalize labels the same way Request decoding does (e.g., trim using the same
TrimmedString logic) before creating the Set: in the loop over input.questions
compute const labels = q.options.map(o => normalizeLabel(o.label)) and use new
Set(labels).size !== labels.length to detect duplicates, and include the
normalized labels in the thrown Error message; keep the rest of the flow
(Schema.decodeUnknownSync(Request), QuestionID.ascending, Deferred.make,
InstanceState.get) unchanged.

In `@packages/opencode/src/session/compaction.ts`:
- Around line 404-418: The code only hides prior messages when
latestPrior.tailStartId exists, so if a completed compaction summarized the
entire filtered history (latestPrior present but tailStartId undefined)
subsequent rounds will re-summarize the same head; update the logic around
completedCompactions/prior/latestPrior to treat an absent tailStartId as a
full-summary boundary by marking all prior indices as hidden (e.g., add all
indices 0..history.length-1 to hidden) and also clear/replace any stored
boundary field (references: latestPrior.tailStartId, latestPrior.summary,
compactionPart.tail_start_id and selected.tail_start_id) so the persisted
boundary reflects that the whole history was summarized; apply the same fix
where compactionPart.tail_start_id is handled later (lines around 497-501) to
avoid keeping a stale tail_start_id.

In `@packages/opencode/src/tool/agent.ts`:
- Around line 60-76: The resume logic currently swallows all errors from
sessions.get (via Effect.catchCause(() => Effect.succeed(undefined))), which
turns transient store failures into silently forking a new subagent; change this
so only an explicit "not found" / missing-session case falls back to undefined
while other errors are propagated. In the block that uses agentSessionID and
calls sessions.get(SessionID.make(agentSessionID)), replace the broad
Effect.catchCause handler with logic that inspects the failure cause and returns
undefined only when the cause indicates a not-found/missing session, otherwise
re-raise or fail the effect; keep the preceding validation using
Schema.decodeUnknownExit(SessionID) intact. Use the existing symbols
agentSessionID, SessionID.make, sessions.get and Effect.catchCause (or
Effect.catchSome/catchTag as appropriate) to implement this selective fallback.

In `@packages/opencode/src/tool/bash.ts`:
- Around line 584-589: The description string is interpolating
Truncate.MAX_LINES and Truncate.MAX_BYTES, which can be out of sync with the
actual truncation used by run(); instead call the truncation limits provider
(trunc.limits() or yield* trunc.limits() depending on context) and interpolate
its returned max_lines / max_bytes values into the description (replace usages
of Truncate.MAX_LINES and Truncate.MAX_BYTES). Update the description creation
near where description: DESCRIPTION.replaceAll... is built so it queries the
current truncation limits from trunc.limits() (or the existing trunc variable)
and uses those numeric values for ${maxLines} and ${maxBytes}.

In `@packages/opencode/src/tool/grep.ts`:
- Around line 31-32: The execute parameter type should be derived from the
Parameters schema instead of an inline object to prevent type drift: change the
execute signature in the Tool.define call (the execute function that currently
takes params: { pattern: string; path?: string; include?: string }) to use
Schema.Schema.Type<typeof Parameters> as the params type, and add/ensure an
import for Schema if not already present so the compiler can resolve
Schema.Schema.Type.

In `@packages/opencode/src/tool/lsp.ts`:
- Around line 42-45: The execute parameter uses an inline type instead of the
schema-derived type, so update the execute signature to use
Schema.Schema.Type<typeof Parameters> for its args to prevent type drift; locate
the execute function definition in this file (the execute: (args: {...}, ctx:
Tool.Context) => ...) and replace the inline args type with
Schema.Schema.Type<typeof Parameters> (ensure Parameters is the schema exported
in this module and Schema is imported) so the compiler will catch future schema
changes.

In `@packages/opencode/test/file/ripgrep.test.ts`:
- Around line 86-97: The test currently writes "needle" only to match.ts so a
broken glob implementation that searches all files still passes; update the
Bun.write for skip.txt to include the string "needle" (so skip.txt contains the
match) and keep the rg.search call using pattern: "needle" and glob: ["*.ts"],
then strengthen assertions after run(...) to still expect result.items.length
=== 1 and assert that none of the returned item paths contain "skip.txt" (e.g.
check result.items for absence of "skip.txt") to ensure the glob filter excludes
non-*.ts files; reference Bun.write, Ripgrep.Service.use / rg.search, pattern,
glob, and result.items when making the changes.
- Around line 199-210: The test currently calls the direct path
Ripgrep.Service.use with rg.search which doesn't exercise the worker-backed code
path; change the test to invoke the worker-backed entry (e.g. replace
Ripgrep.Service.use(...) with the worker-backed variant such as
Ripgrep.Service.useWorker(...) or the project’s equivalent worker API) and call
the same search (rg.search({ cwd: tmp.path, pattern: "needle" })) inside that
worker callback so the worker-only code path is exercised in this test.

Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/cli/cmd/debug/ripgrep.ts`:
- Around line 93-103: The command currently writes only results.items to stdout,
losing search debug metadata (results.partial and results.partialReason); update
the output to include the full results object returned from Ripgrep.Service.use
-> svc.search (or at least include results.partial and results.partialReason
alongside items) so partial-I/O and invalid-pattern cases are preserved in the
debug output; replace the
process.stdout.write(JSON.stringify(results.items,...)) call in ripgrep.ts with
a write of the complete results JSON (or a composed object { items, partial,
partialReason }) to retain the metadata.

In `@packages/opencode/src/file/ripgrep.ts`:
- Around line 224-225: The current check uses a truthy test on input.limit which
drops explicit 0 and makes ripgrep unbounded; update the logic where args are
built (the block that currently does if (input.limit)
args.push(`--max-count=${input.limit}`)) to either: 1) check for undefined
explicitly (if (input.limit !== undefined) ...) and push the --max-count when
provided, or 2) validate/reject zero earlier (e.g., throw or normalize when
input.limit === 0) so callers cannot accidentally pass 0; adjust the code that
pushes to args (the args.push(...) lines) accordingly to preserve an explicit
limit of 0 if you choose the explicit-check approach.

In `@packages/opencode/src/server/instance/file.ts`:
- Around line 24-28: Update the /find response schema inside the resolver so the
top-level object returned by Ripgrep.search() includes partialReason; currently
only items and partial are declared. Add a new property (e.g., partialReason:
z.string().nullable().optional()) next to items and partial in the z.object so
generated clients/docs can distinguish reasons like "invalid_pattern" vs
"partial_io" (reference the resolver and the Ripgrep.SearchMatch.zod usage to
locate the schema).

In `@packages/opencode/src/tool/todo.ts`:
- Around line 9-18: The TodoItem schema currently uses free-form strings for
status and priority; change those fields to closed enums so only allowed values
are accepted: replace status: Schema.String... with status:
Schema.Enum(["pending","in_progress","completed","cancelled"]) and replace
priority: Schema.String... with priority: Schema.Enum(["high","medium","low"]);
update the TodoItem declaration (and keep Parameters.todos referencing TodoItem)
so callers cannot submit invalid values and existing code that checks status ===
"completed" continues to work.

In `@packages/opencode/src/tool/write.ts`:
- Around line 37-38: The execute function currently hand-writes the decoded
params shape ({ content: string; filePath: string }) instead of using the
schema-derived Parameters type; update the execute signature to use the
Parameters type (i.e., accept params: Parameters) so it matches the pattern in
webfetch.ts/todo.ts and conforms to the Tool.Def contract, keeping ctx as
Tool.Context and preserving the function body.

In `@packages/opencode/src/file/ripgrep.ts`:
- Around line 297-316: The cached binary-resolution Effect assigned to filepath
is turning filesystem errors into defects by wrapping fs.isFile(...) and
fs.ensureDir(...) calls with Effect.orDie; remove Effect.orDie from the three
calls (the two fs.isFile(...) usages and the fs.ensureDir(...) call) so those IO
errors propagate through the declared error channel (PlatformError | Error)
instead of becoming defects—locate the Effect.gen block that builds filepath and
adjust the usages of fs.isFile and fs.ensureDir accordingly, leaving the rest of
the logic (which(...), path construction, download logic) unchanged.

In `@packages/opencode/src/question/index.ts`:
- Around line 265-276: In the reply loop that iterates questions (using
variables questions, input.answers and q.multiple), add a check for empty
selections (answer.length === 0) and treat them like rejects: log a warning,
pending.delete(input.requestID), and yield* Deferred.fail(existing.deferred, new
RejectedError()); for single-select also keep the existing check for
answer.length > 1; thus modify the block around q.multiple to first reject when
answer.length === 0 (for both single- and multi-select) and continue using the
current reject flow (log + pending.delete + Deferred.fail on existing.deferred)
for invalid multiple selections as already implemented.
- Around line 206-214: The uniqueness check currently uses raw input.questions
so labels like "foo" and " foo " bypass dedupe; decode and normalize before
checking by running Schema.decodeUnknownSync(Request) (or otherwise applying
TrimmedString) and perform the duplicate-label check against the
decoded/normalized info.questions (or transformed labels array) instead of
input.questions; update the logic around input.questions -> labels to
trim/normalize each option.label (or use the decoded info.questions) before
creating the Set so duplicates with whitespace are caught (also apply same
change to the other check that mirrors this logic).

In `@packages/opencode/src/session/compaction.ts`:
- Around line 411-417: The current logic only hides prior messages when
latestPrior.tailStartId is set; change it so the presence of latestPrior alone
triggers hiding the previously-summarized head. Concretely, in the block around
latestPrior (the variables prior, latestPrior, tailStartId, history, hidden),
compute tailIndex = latestPrior.tailStartId ? history.findIndex(m => m.info.id
=== latestPrior.tailStartId) : history.findIndex(m => m.info.id ===
latestPrior.id) (or fallback to history.length if not found), then run the same
for-loop for (let i = 0; i < tailIndex; i++) hidden.add(i) so a missing
tailStartId still hides the entire prior summary range.

In `@packages/opencode/src/session/message-v2.ts`:
- Around line 22-33: truncateToolOutput can produce a string longer than
maxChars when the suffix itself exceeds maxChars; in truncateToolOutput(text,
maxChars) compute reserve as you already do and if reserve >= maxChars (or
sliceLen === 0) return only the suffix truncated to maxChars (e.g.,
suffixTemplate(omitted).slice(0, maxChars)) so the function always returns a
string whose length <= maxChars; update the logic in truncateToolOutput to
handle this edge case (refer to the suffixTemplate, reserve, sliceLen, and
omitted variables).

In `@packages/opencode/src/tool/edit.ts`:
- Around line 99-104: The code currently allows params.newString to inject a BOM
by using desiredBom = source.bom || next.bom; change this to preserve the
original BOM only (desiredBom = source.bom) so edits cannot invisibly add a BOM;
update the blocks that call Bom.readFile, Bom.split, set contentOld/contentNew,
and compute diff (the region using variables source, next, desiredBom,
contentOld, contentNew, createTwoFilesPatch, trimDiff) to use source.bom-only
semantics and apply the same fix in the other occurrence mentioned (the block
around lines 140-143).
- Around line 94-96: The code currently swallows all errors from
afs.stat(filePath) by returning undefined, which maps permission/IO errors to
"missing file"; change the catch to only convert a NotFound error into undefined
and rethrow any other error instead. Concretely, replace the broad
Effect.catch(() => Effect.succeed(undefined)) on the afs.stat(filePath) call
with a handler that inspects the caught error (e.g., error.tag or instance) and
returns Effect.succeed(undefined) only when it indicates NotFound, otherwise
rethrows or returns Effect.fail(error); apply the exact same change to the other
afs.stat usage with the same pattern so only NotFound is translated to "missing
file" and all other filesystem errors propagate.

In `@packages/opencode/src/tool/grep.ts`:
- Around line 81-82: The code returns the canonical empty ("No files found")
early when result.items.length === 0, but ignores result.partial from
Ripgrep.Service.search(); change the branch that returns empty to
preserve/augment the empty shape when result.partial is true by appending the
skipped-path warning (the same warning used elsewhere) to the empty response so
unreadable/skipped paths are reported as a partial miss; specifically update the
check around result.items.length === 0 (and the similar block at lines 142-145)
to inspect result.partial and merge the skipped-path message into the returned
empty object instead of returning a clean miss.

In `@packages/opencode/src/tool/lsp.ts`:
- Around line 42-45: The execute handler's args type is manually duplicated;
update the signature to bind args to Schema.Schema.Type<typeof Parameters> so
TypeScript enforces the decoded shape: replace the inline args type for execute
with args: Schema.Schema.Type<typeof Parameters>, keep ctx: Tool.Context, and
then adjust any internal references that expect the previous shape to match the
Parameters-derived type; ensure the symbol Parameters is imported/visible in
this file and update any downstream uses of execute to the new typed shape.

In `@packages/opencode/src/tool/truncate.ts`:
- Around line 76-83: The limits() generator currently swallows errors from
configSvc.value.get() and returns defaults; change it so only the absence of
Config.Service (Option.isNone(configSvc)) falls back to MAX_LINES/MAX_BYTES, but
if configSvc exists then call configSvc.value.get() without the Effect.catch
wrapper so any read/parse failures propagate (i.e., remove the Effect.catch(()
=> Effect.succeed(undefined)) around configSvc.value.get()); update the
subsequent handling of cfg accordingly in the Truncate.limits function.

In `@packages/opencode/src/tool/write.ts`:
- Around line 70-77: The recomputed diff (computed from finalContent after
Bom.syncFile/formatting using createTwoFilesPatch + trimDiff) is never
propagated to the approval preview or bus events; update the code so the
post-format diff is actually used — either move the formatting+sync+diff
recomputation so it occurs before ctx.ask(...) (so ctx.ask receives the
post-format diff) or ensure the bus event and any downstream consumers use the
recomputed diff/finalContent instead of the original diff (referencing variables
filepath, contentOld, contentNew, finalContent, diff and functions/methods
Bom.syncFile, format.file, createTwoFilesPatch, trimDiff, and ctx.ask).

In `@packages/opencode/test/file/ripgrep.test.ts`:
- Around line 83-97: The test currently writes "needle" only into match.ts so it
won't detect if glob filtering is ignored; update the tmpdir init in the test
(the async init passed to tmpdir) to write "needle" into skip.txt as well (e.g.,
include "const value = 'needle'\n" in skip.txt), then after calling
Ripgrep.Service.use((rg) => rg.search(...)) add an assertion that no returned
item's path contains "skip.txt" (or explicitly expect all result.items paths to
notContain "skip.txt") while keeping the existing
expect(result.items).toHaveLength(1) and checks for "match.ts" and "needle" to
ensure non-*.ts matches are excluded by the glob option on rg.search.

Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/cli/cmd/debug/file.ts`:
- Around line 81-84: The output variable `files` from the Ripgrep call (via
AppRuntime.runPromise -> Ripgrep.Service.use -> rg.tree) is already a formatted
string, so change the debug print to emit raw text instead of JSON-encoding it;
replace the JSON.stringify usage with a plain text print (e.g.,
console.log(files) or process.stdout.write(files + '\n')) so the tree is printed
with proper newlines and formatting.

In `@packages/opencode/src/session/message-v2.ts`:
- Around line 748-750: The interrupted-tool branch still uses
part.state.metadata.output verbatim, bypassing the compaction cap; update the
branch that sets outputText for non-completed/error tool parts to pass the
interrupted output through truncateToolOutput(...) (same as the completed
branch) so toolOutputMaxChars is applied uniformly—search for the outputText
assignment and the use of part.state.metadata.output in message-v2.ts and
replace the raw metadata output with
truncateToolOutput(part.state.metadata.output, options?.toolOutputMaxChars) (or
reuse the existing truncateToolOutput call used for part.state.output) to
enforce the cap.

In `@packages/opencode/src/tool/edit.ts`:
- Line 48: The schema description for filePath (Schema.String.annotate) is too
strict—update its description to reflect the actual behavior of the edit tool
which accepts both absolute and relative paths (relative paths are resolved per
the implementation) instead of saying it must be an absolute path; change the
text in the filePath annotation to indicate it accepts absolute or relative
paths and how relative paths are interpreted.

In `@packages/opencode/src/tool/webfetch.ts`:
- Line 19: Update the Schema description for the timeout field in webfetch.ts
(the timeout: Schema.optional(...) declaration) to advertise the lower bound as
well (e.g. "Optional timeout in seconds (1–120)"/"must be a positive number up
to 120") so callers know 0 and negatives are invalid; keep the runtime guards in
execute() (the checks around lines rejecting 0/negative values) as the
enforcement mechanism but make the Schema description reflect that timeout must
be positive and not zero.

Outside diff comments:
In `@packages/opencode/src/agent/prompt/compaction.txt`:
- Around line 9-10: Remove the language-override sentence from the compaction
system prompt so the fixed Markdown headings from
packages/opencode/src/session/compaction.ts aren’t translated; specifically edit
packages/opencode/src/agent/prompt/compaction.txt to delete the line "Respond in
the same language as the conversation." and keep the rest of the template intact
so compaction.ts continues to append the exact Markdown section headings and
order without forcing language changes.

In `@packages/opencode/src/session/compaction.ts`:
- Around line 497-501: The current conditional only updates the compaction part
when selected.tail_start_id is truthy, so a later selection that clears the tail
(undefined) won't persist that change; change the condition to run whenever
compactionPart exists and its tail_start_id differs from selected.tail_start_id
(i.e., use compactionPart && compactionPart.tail_start_id !==
selected.tail_start_id) and call session.updatePart with tail_start_id set to
selected.tail_start_id (allowing it to be cleared), so completedCompactions()
sees the authoritative cleared value.

In `@packages/opencode/src/tool/glob.ts`:
- Around line 11-27: The Parameters schema is declared with Schema.Struct but
the handler re-specifies the fields; change Parameters to use Schema.Class for
multi-field Effect schemas and make it the single source of truth, then update
GlobTool.execute's parameter typing to derive from typeof Parameters (e.g.,
execute: (params: typeof Parameters.Type, ctx: Tool.Context) => ...) so the
runtime and TypeScript types stay in sync; ensure any code that previously
referenced the manual param shape (in GlobTool, execute, and any helper
functions) uses the derived type and remove the duplicated manual declaration.

Duplicate comments:
In `@packages/opencode/src/tool/lsp.ts`:
- Around line 41-45: The execute handler in lsp.ts uses a handwritten args shape
so Parameters can drift from the runtime-decoded input; update the execute
signature to type its first parameter as Schema.Schema.Type<typeof Parameters>
(instead of the inline { operation: ...; filePath: ... } shape), ensuring you
import/namespace Schema the same way other tools do and adjust any callers/uses
inside execute to the strongly-typed params; specifically modify the execute
definition that references Parameters to use Schema.Schema.Type<typeof
Parameters> so compile-time types match the runtime decoder.

In `@packages/opencode/src/tool/write.ts`:
- Around line 57-76: The posted diff recomputes diff after formatting but never
uses it because ctx.ask(...) is called earlier with the original metadata.diff;
fix by ensuring the metadata passed to ctx.ask contains the post-format diff:
perform formatting and Bom.syncFile (using format.file and Bom.syncFile) before
constructing the metadata object (or recompute and replace metadata.diff right
before yielding ctx.ask), so that the trimDiff(createTwoFilesPatch(...)) result
assigned to diff is the value included in the metadata sent in ctx.ask;
reference variables/functions: diff, ctx.ask, metadata.diff, fs.writeWithDirs,
format.file, Bom.syncFile, createTwoFilesPatch, trimDiff.

In `@packages/opencode/test/file/ripgrep.test.ts`:
- Around line 83-97: The test "search returns matched rows with glob filter" is
too weak because skip.txt lacks the search term so the test would pass even if
the glob filter is ignored; update the tmpdir init used by Ripgrep.Service.use
in the test to write "needle" into skip.txt (or another matching string) and
then assert that rg.search({ cwd: tmp.path, pattern: "needle", glob: ["*.ts"] })
returns only the match from "match.ts" (expect result.items length 1 and that
the skipped file's match is not present), ensuring the glob filtering is
actually enforced by Ripgrep.Service.use -> rg.search.

Verify each finding against the current code and only fix it if needed.

Inline comments:
In `@packages/opencode/src/file/ripgrep.ts`:
- Around line 469-470: The loop in ripgrep.ts currently filters files with
file.includes(".opencode") which incorrectly matches any path containing that
substring; instead split the path into segments and test for an exact segment
named ".opencode" (e.g., split the file string on path separators or use
path.sep/path utilities) so only entries where one segment equals ".opencode"
are skipped — update the for (const file of list) check to test
pathSegments.includes(".opencode") using the existing variables 'file' and
'list'.

Outside diff comments:
In `@packages/opencode/src/file/index.ts`:
- Around line 392-403: The code pushes directory keys using
path.dirname(current) and then appending "/" which on Windows yields mixed
separators (e.g., "src\\nested/"); update the loop that computes dir (the block
using path.dirname(current) and pushing to next.dirs and seen) to normalize dir
to a consistent forward-slash form before adding the trailing slash (e.g.,
convert backslashes to "/" or use a POSIX-normalizer) so stored keys are
uniform; ensure you check seen against the normalized key and push normalized +
"/" to next.dirs (referencing the loop that uses files, current,
path.dirname(current), seen, and next.dirs).

Duplicate comments:
In `@packages/opencode/src/session/compaction.ts`:
- Around line 405-418: The code currently only hides messages when
latestPrior.tailStartId is set; add a branch to also hide all prior history when
a completed compaction exists but tailStartId is undefined (meaning it
summarized all previous messages). Concretely, after computing latestPrior, if
latestPrior exists and latestPrior.tailStartId is undefined, mark indices
0..history.length-1 (or at least all indices before the current head) as hidden
(e.g., loop i from 0 to history.length-1 and hidden.add(i)), preserving reuse of
previousSummary; keep the existing tailStartId-based logic for the other case.

Inline comments:
In `@packages/opencode/src/tool/read.ts`:
- Around line 27-35: The Parameters export currently uses Schema.Struct; replace
it with Schema.Class to follow the Effect multi-field schema convention: change
the declaration of Parameters (export const Parameters = Schema.Struct({...}))
to use Schema.Class({...}) while preserving the same fields (filePath, offset,
limit) and their annotations so the schema shape and descriptions remain
identical.

Duplicate comments:
In `@packages/opencode/src/tool/read.ts`:
- Around line 28-34: The parameter docs on the Schema annotations are too
narrow: update the Schema annotations for filePath, offset, and limit in
packages/opencode/src/tool/read.ts so they reflect actual runtime behavior —
change filePath description to allow absolute or relative paths (since the code
resolves relative paths), change offset to say it is a 1-indexed start for
either file line reads or directory-entry pagination, and change limit to say it
limits the maximum number of lines or directory entries returned (defaults to
2000); adjust the brief wording for clarity so callers see the correct behavior
used by the resolve-relative-path and directory-pagination logic in this file.
