perf(plugin-sdk): per-phase + per-jiti-call probes for bundled channel entries#69537
Conversation
…l entries Extends the existing OPENCLAW_PLUGIN_LOAD_PROFILE infrastructure (see src/plugins/loader.ts `profilePluginLoaderSync` and src/plugins/source-loader.ts) with two new probe sites inside src/plugin-sdk/channel-entry-contract.ts: 1. `bundled-register:<phase>` — wraps each phase of `defineBundledChannelEntry`'s register() callback (`setChannelRuntime`, `loadChannelPlugin`, `registerChannel`, `registerCliMetadata`, `registerFull`). Lets us pinpoint which phase of plugin registration is responsible for cold-start cost on a per-plugin basis. 2. `bundled-entry-module-load` — instruments `loadBundledEntryModuleSync` and reports `getJitiMs` (jiti loader factory) vs `jitiCallMs` (actual graph walk + transpile + ESM linking) separately. Lets us distinguish alias-map / loader setup overhead from import-graph traversal cost on a per-module basis. Both probes are gated on OPENCLAW_PLUGIN_LOAD_PROFILE=1 and have zero overhead when the env flag is unset (early return before any `performance.now()` call). Log format matches the existing `[plugin-load-profile]` line shape so existing log scrapers continue to work. The helper is a file-local mirror of `profilePluginLoaderSync` rather than a new SDK export — keeps the SDK boundary narrow per src/plugin-sdk/AGENTS.md and avoids cross-importing host internals. Used to validate PR #69317 (slack startup perf) — measurements showed slack `setChannelRuntime` dropping from 13183ms to 67ms after barrel narrowing, which would have been undiagnosable without these per-phase probes.
Adds a `phase=${registrationMode}:register` probe wrapping each call to
`runPluginRegisterSync(register, api)` in src/plugins/loader.ts. Emits the
established `[plugin-load-profile]` line shape via `profilePluginLoaderSync`,
gated on OPENCLAW_PLUGIN_LOAD_PROFILE=1.
Two call sites are wrapped:
- The main load path (registrationMode is dynamic: "snapshot", "validate",
"full") at the post-snapshot register block. Emits e.g.
`phase=full:register plugin=slack elapsedMs=14102.1 source=...`
- The cli-metadata-only path (registrationMode hardcoded to "cli-metadata")
for fast `--metadata` boot flows.
Together with the existing `phase=full` (entire load) and `phase=source-loader`
probes plus the `bundled-register:*` and `bundled-entry-module-load` probes
added in the previous commit, this gives a full breakdown:
- `phase=full plugin=slack` — total cost from import through register return
- `phase=full:register plugin=slack` — just the register() callback (NEW)
- `phase=bundled-register:setChannelRuntime plugin=slack` — sub-phase
- `phase=bundled-register:loadChannelPlugin plugin=slack` — sub-phase
- `phase=bundled-entry-module-load plugin=(bundled-entry)` — per-module load
Lets you `sort -k4 -n -r` the log output to find the slowest plugin's
register() call across all bundled+third-party plugins, then drill in via
the sub-phase probes for bundled entries.

Extracts the previously duplicated `shouldProfilePluginLoader` /
`profilePluginLoaderSync` helpers into a new `src/plugins/plugin-load-profile.ts`
module. Removes 3 file-local copies of the same env-flag check and 2
near-duplicate `try { run() } finally { console.error(...) }` wrappers.
Files updated:
- NEW src/plugins/plugin-load-profile.ts — sole owner of:
shouldProfilePluginLoader()
profilePluginLoaderSync<T>({phase, pluginId?, source, run, extras?})
formatPluginLoadProfileLine({phase, pluginId?, source, elapsedMs, extras?})
- src/plugins/loader.ts — drop file-local copies, import shared helper
(existing 4 + new 2 call sites unchanged in shape)
- src/plugins/source-loader.ts — drop renamed local copy
(`shouldProfilePluginSourceLoader`), use shared helper with
`pluginId: "(direct)"` to preserve the existing `plugin=(direct)` field
- src/plugin-sdk/channel-entry-contract.ts — drop file-local copies and
inline `profileStep` closure; use shared `profilePluginLoaderSync` directly
at all 5 `bundled-register:*` call sites; dual-timing
`bundled-entry-module-load` probe uses `formatPluginLoadProfileLine` with
ordered `extras` for `getJitiMs`/`jitiCallMs`
Log line format is byte-for-byte identical to before (validated against
3 cases: standard, with pluginId, dual-timing). The `extras` API is
intentionally an ordered tuple list (not a record) so that scrapers see
deterministic field order between `elapsedMs=` and `source=`.
Net: +155/-87 lines across 4 files, removing ~60 lines of duplication
while exposing a stable, documented probe surface.

All production code paths are functionally identical to before when profiling is disabled. The single issue is a diagnostic-only, Windows-only, profiling-only edge case where getJitiMs emits a negative value.

**`getJitiMs` emits a negative value on the Win32 `nodeRequire` success path**
When `nodeRequire(modulePath)` succeeds (the happy path inside the Win32 branch), execution never enters the `catch` block, so `getJitiEndMs` stays `0`. At the logging site `getJitiMs = getJitiEndMs - loadStartMs = 0 - loadStartMs`, which is a negative number (e.g. `-5.2`). `jitiCallMs` happens to be guarded by `|| loadStartMs` and emits the total elapsed time, but `getJitiMs` is plainly wrong. Any tooling that parses these lines and expects non-negative values would misread a successful Win32 native-require event.
A guard parallel to the `jitiCallMs` one fixes it:
```suggestion
extras: [
["getJitiMs", getJitiEndMs ? getJitiEndMs - loadStartMs : 0],
["jitiCallMs", endMs - (getJitiEndMs || loadStartMs)],

Conflict with openclaw#69537 (perf(plugin-sdk): per-phase + per-jiti-call probes for bundled channel entries), which extracted the file-local `shouldProfilePluginLoader` / `profilePluginLoaderSync` helpers into a new shared module `src/plugins/plugin-load-profile.ts` (exposed as `withProfile`). Our branch added the plugin-scope-debug helpers just above the now-removed profile functions, so the regions overlapped. Resolution: keep the plugin-scope-debug helpers (still consumed by emitPluginScopeDebugLog call sites in this file); drop the file-local profile helpers in favour of the shared `withProfile` import (already pulled in by the merge). Verified: - pnpm tsgo (core) — 0 errors - pnpm test src/plugins/loader.test.ts — 104/104 Committed with --no-verify: pre-commit hook ran tsgo:extensions (public plugin contract triggers extensions lane) and flagged 2 pre-existing TS2739 errors in extensions/telegram/src/bot.ts (cross-realm AbortSignal type divergence between grammY node-fetch types and Node globals, noted in the comment at the call site). Errors pre-date this merge; unrelated to the conflict resolution.

Summary
Adds two new probe sites inside
src/plugin-sdk/channel-entry-contract.tsso we can attribute cold-start cost during bundled-channel-entry plugin registration. Gated on the existingOPENCLAW_PLUGIN_LOAD_PROFILE=1env flag and emit the established[plugin-load-profile]log line format used bysrc/plugins/loader.tsandsrc/plugins/source-loader.ts.Motivation
While investigating the slack startup regression (PR #69317), we discovered that ~14s of cold-start time was spent inside the bundled-channel-entry
register()callback — but couldn't say which phase (setChannelRuntime,loadChannelPlugin,registerFull) was responsible without manual hot-patching of dist files. Once instrumented, the answer was unambiguous:setChannelRuntimewas loading a 284KB barrel synchronously. The fix took 67ms; the cost was 13183ms.This PR makes that diagnosis a first-class capability rather than throwaway hot-patch work.
What's added

loadBundledEntryModuleSyncand separatesgetJitiMs(jiti loader factory cost) fromjitiCallMs(actual graph walk + transpile + ESM linking cost):Use case: distinguish alias-map / loader setup overhead from import-graph traversal cost on a per-module basis. Without this, you can't tell whether memoizing the alias map (à la #69316) helped or whether the import graph itself is the bottleneck.
