Enhance async tool execution and error handling in Hermes agent for A…#19
Conversation
…tropos integration - Updated `.gitignore` to exclude `testlogs` directory. - Refactored `handle_web_function_call` in `model_tools.py` to support running async functions in existing event loops, improving compatibility with Atropos. - Introduced a thread pool executor in `agent_loop.py` for running synchronous tool calls that internally use `asyncio.run()`, preventing deadlocks. - Added `ToolError` class to track tool execution errors, enhancing error reporting during agent loops. - Updated `wandb_log` method in `hermes_base_env.py` to log tool error statistics for better monitoring. - Implemented patches in `patches.py` to ensure async-safe operation of tools within Atropos's event loop. - Enhanced `ToolContext` and `terminal_tool.py` to utilize the new async handling, improving overall tool execution reliability.

🔴 Critical: _create_environment() now respects the selected backend, but this call never passes ssh_config. When TERMINAL_ENV=ssh, file tools fail immediately with ValueError: SSH environment requires ssh_host and ssh_user to be configured, even if those env vars are set, because _create_environment() only reads them through its explicit ssh_config argument. Please thread the same SSH config that terminal_tool() passes here and add a regression test for non-local backends.

With concurrent rollouts this can mute unrelated tasks while one rollout is cleaning up its browser session.
Suggestions
- Add a focused regression test around error aggregation / async cleanup paths so the Atropos-specific behavior is covered without relying only on the existing modal/web smoke tests.
Looks Good
- Moving environment creation out of
_env_lockinterminal_tool/file_toolsis the right direction for avoiding rollout-wide stalls. - The Atropos compatibility shim is well-scoped and the updated tool-path smoke tests still pass locally.

ToolError aggregation currently requires both error and a negative exit_code, but several tools return {"error": ...} without any exit_code (for example write_file_tool). Those failures won't make it into result.tool_errors, so the new W&B metrics under-count the exact cases this PR is trying to surface. I'd key off error first and only use exit_code for extra classification.

This mutates os.environ, so the quiet flag becomes process-global for the duration of the cleanup. In Atropos runs with concurrent rollouts, another task can lose terminal/browser logs while this cleanup is in progress. It would be safer to thread a quiet flag into cleanup_browser() (or suppress logging locally) instead of flipping a shared env var.

Hermes Agent Review
Post-merge follow-up review. I re-checked the PR diff locally, ran py_compile on the touched Python files, and ran pytest tests/test_modal_terminal.py -q (6 passed).
Findings
- Critical —
environments/hermes_base_env.py:374:train/tool_error_detailslogs raw tool arguments to W&B. Failing tool arguments can contain tokens, credentials, local paths, or command fragments, so this pushes potentially sensitive runtime data into external telemetry. Please redact/summarize arguments before logging or gate full details behind an explicit debug flag. - Warning —
environments/tool_context.py:52-60:_run_tool_in_thread()detects the running event loop and then blocks it withfuture.result(timeout=300)on a one-off executor. That avoids nestedasyncio.run(), but it also serializes verifier work and imposes a hidden 5-minute cap on tool calls made throughToolContext. An awaitablerun_in_executorpath would preserve async-safety without blocking the loop.
The concurrency cleanup in tools/terminal_tool.py and the new ToolError struct in environments/agent_loop.py both look solid.

🔴 Critical: ToolContext.terminal() was moved onto a worker thread, but the other convenience wrappers still call handle_function_call() directly. That means reward code using read_file, write_file, search, web_extract, or browser helpers can still hit the same nested-event-loop path this PR is trying to eliminate. Please route those wrappers through the same async-safe helper so the fix applies consistently across the ToolContext API.

exit_code exists and is negative. Several Hermes tools (for example read_file / write_file / search) return {"error": ...} without an exit_code, so those failures disappear from the metrics even though this PR is explicitly improving error reporting. Consider logging any truthy error, then optionally using exit_code only to refine severity.

Hermes Agent Review
I found one blocking issue in the new async/file-tool environment setup and one follow-up test gap.
Blocking
tools/file_tools.py:54bypasses the per-task local workdir logic thatterminal_tool()applies. If a rollout hits a file tool before the terminal tool, the environment is created directly in the shared basecwd, and later terminal calls reuse that already-created environment. That breaks rollout isolation for local backends.
Follow-up
- Please add a regression test for the sequence
write_file/read_file -> terminal('pwd')on the local backend so this stays covered.
Validation
python3 -m pytest -q tests/test_modal_terminal.py tests/test_web_tools.py✅- Manual repro on this branch showed
write_file_tool()creating the env at the shared base cwd, and a subsequentterminal_tool('pwd')staying in that shared directory instead of a per-task subdirectory.

Blocking: this creates the file-tool environment straight from config['cwd'] and never applies the local per-task workdir logic from terminal_tool() (_task_workdirs at lines 1337-1344 there). If a rollout uses a file tool before terminal, all local rollouts can land in the shared base cwd, and later terminal calls will reuse that already-created shared environment.

This path also skips the mkdir(parents=True, exist_ok=True) that terminal_tool() does for local task workdirs. In my local repro, TERMINAL_CWD=/tmp/hermes-filetools-review caused write_file_tool() to fail with ENOENT on the first write because the cwd did not exist yet. Please either reuse the same local-workdir creation path as terminal_tool() or explicitly create/validate cwd here.

This path now creates the backing environment with the shared config cwd. terminal_tool() still gives local backends a per-task subdirectory when !HERMES_QUIET, so if a rollout hits read_file/write_file before terminal, the task ends up bound to the shared cwd and later terminal calls reuse that environment. That breaks the isolation guarantee in the comment above (parallel tasks from overwriting each other's files). Can we reuse the same local-workdir derivation here (or centralize env creation) and add a regression test for the file-tool-first path?

Reviewed after checkout. I found two non-blocking issues worth following up:
environments/agent_loop.pyonly records tool errors whenexit_code < 0, so ordinary command failures (for example a verifier/test returning exit code 1) won't show up in the new telemetry.environments/tool_context.pycreates a brand-newThreadPoolExecutor(max_workers=1)for every async-context tool call instead of reusing the module-level executor, which adds avoidable thread churn during rollouts.
Modal terminal smoke tests passed locally (tests/test_modal_terminal.py). Full pytest --collect-only still hits unrelated existing OPENAI_API_KEY collection errors in other tests.

Retrospective review on the merged PR. I re-checked the patch locally (py_compile on the touched Python modules, pytest -q tests/test_modal_terminal.py = 6 passed, and pytest --collect-only -q tests/test_web_tools.py = exit 5 / no tests collected).
I also reviewed the existing PR discussion and avoided reposting the earlier findings about file-tool environment setup, tool-error aggregation, and W&B payload logging. The one additional follow-up I found is below.
Warnings
- tools/terminal_tool.py:1459 — the new retry/failure diagnostics print the raw command text to stdout. Failed terminal commands often contain credentials, bearer tokens, SSH targets, or private filesystem paths, so this can leak sensitive runtime data into training logs / CI logs whenever a command retries or fails.
Suggestion
- Keep the retry logging, but redact the command payload (or gate full command echoing behind an explicit debug flag) before printing it.
Looks Good
- The async/thread handoff direction still looks sensible.
- The touched Python files compile cleanly, and the existing modal terminal smoke tests still pass locally.

Critical
- tools/file_tools.py:59 —
_get_file_ops()now creates non-local environments without passing SSH config into_create_environment(). I reproduced this locally withTERMINAL_ENV=ssh,TERMINAL_SSH_HOST=example.com, andTERMINAL_SSH_USER=alice:terminal_tool('pwd')reaches the SSH connection attempt, butread_file_tool('/tmp/x')immediately returns{"error": "SSH environment requires ssh_host and ssh_user to be configured"}. That means file tools regress on SSH backends even when the terminal tool is configured correctly.
Warnings
- environments/terminal_test_env.py:132 — The default tokenizer changed to
NousResearch/q-30b-t-h45-e1, which appears gated/private from an unauthenticated environment (https://huggingface.co/NousResearch/q-30b-t-h45-e1/raw/main/tokenizer_config.jsonreturns 401 here). The previous default was publicly fetchable, so this makesTerminalTestEnvharder to run in fresh dev/CI setups.
Suggestions
- Add a regression test that exercises file tools under a non-local backend, especially SSH. This regression is exactly the kind of backend-specific breakage that unit coverage should catch.
Looks Good
- Moving environment creation outside
_env_lockinterminal_tool.py/file_tools.pyis a good concurrency improvement. - Capturing tool-execution failures in

Found two blocking issues before I would rely on this in Atropos:
ToolContextstill bypasses the new async-safe path forread_file()/write_file()/search(), so verifier code can still call backend-dependent file operations directly from the event-loop thread.- There are no real regression tests for the new async/threading behavior. The closest existing tests (
tests/test_modal_terminal.py) currently return booleans instead of asserting, so pytest reports them as passing even when they would evaluate toFalse.

Retrospective review on the merged PR, focused on whether the automated tests actually cover the new async/tool-execution behavior.
Main finding
I do not think the current test evidence is strong enough for the new behavior introduced in:

Why
python3 -m py_compileon the touched Python modules passed.pytest -q tests/test_modal_terminal.pyreported6 passed, but every test only returnsboolinstead of asserting. Pytest emittedPytestReturnNotNoneWarningfor all six cases, which means these tests can report success without actually failing the suite when the helper returnsFalse.pytest -q tests/test_web_tools.pyfailed during collection becausefirecrawlis not installed in this environment.- I could not find focused regression coverage for the new async thread-handoff / environment-creation / tool-error-tracking paths changed by this PR.
Verdict

- I could not find automated tests covering concurrent env instances with different

I only posted the new inline note below to avoid duplicating issues already covered elsewhere on this PR.

os.environ, so concurrent HermesAgentBaseEnv instances can overwrite each other. If one rollout sets TERMINAL_ENV=modal while another expects local or ssh, later tool calls read whichever value won the race and can run against the wrong backend. Please keep backend selection task/env-local (for example on the env/context) instead of mutating a shared env var, and add a regression test that exercises two env instances with different terminal_backend values in the same process.

Hermes Agent Review
Post-merge re-review using the REST flow (with gh only as a token source).
What I checked:
git diff 578a5fb6..d999d987on the PR snapshotpython3 -m py_compileon the touched Python modulespytest -q -o addopts='' tests/test_modal_terminal.py tests/test_web_tools.py- Result: 6 passed, 6 warnings (
PytestReturnNotNoneWarningintests/test_modal_terminal.py)
- Result: 6 passed, 6 warnings (
Review result:
- I did not add new inline comments in this pass.
- The substantive issues I can still defend from the diff are already covered by existing line comments on this PR (file-tool backend parity, async timeout/error handling, raw command/tool-arg logging, and missing regression coverage for the new async paths).
- I’m avoiding duplicate inline noise on a merged PR.
Net: reviewed again, no new non-duplicate line comments to add beyond the issues already called out in-thread.

PR: #19 — Enhance async tool execution and error handling in Hermes agent for Atropos integration
Author: @teknium1
Files changed: 9 (+540 -64)
Reviewed retrospectively after merge. I did not add duplicate inline comments because the existing runlvl review history on this PR already covers the main correctness regressions in tools/file_tools.py, environments/agent_loop.py, environments/tool_context.py, and environments/hermes_base_env.py.
⚠️ Warnings
- Coverage gap: the new async bridge paths in
environments/tool_context.py:44-63,model_tools.py:1194-1204, andenvironments/patches.pyare still only partially covered from what I could verify in this historical checkout. I could not find focused tests importingenvironments/patches.py,ToolContext, orhandle_web_function_call()under a running event loop, so the Atropos-specific behavior is still not directly regression-tested here.
✅ Looks Good

Test Notes
pytest -q -o addopts='' tests/test_web_tools.pycould not be collected on this host becausefirecrawlis not installed.- The newer
tests/run_agent/...coverage from the current tree does not exist in this historical PR checkout, so it was not applicable evidence for PR #19 itself.

PR: #19 — Enhance async tool execution and error handling in Hermes agent for Atropos integration
Author: @teknium1

⚠️ Warnings
- tools/file_tools.py:54 —
_get_file_ops()now creates environments using the configured backend, but it does not mirrorterminal_tool's per-task local workdir logic. If a rollout hits a file tool beforeterminal_tool, the task is created directly in the shared cwd instead ofhermes-<task>-*, so parallel local rollouts can still overwrite each other's files. I reproduced this on the PR head:read_file_tool(..., task_id='taskB')created an env withcwd='.',taskBwas absent from_task_workdirs, and a subsequentterminal_tool('pwd', task_id='taskB')resolved to the shared repo root.
💡 Suggestions
- Add a regression test for the file-first path (e.g. local backend +
read_file_tool/write_file_toolbefore any terminal call) and for the new async-safe execution path. There are no test changes in this PR, so the concurrency fix is currently unguarded.
✅ Looks Good
- The separation between loop-level tool execution changes, Modal patching, and wandb error logging is easy to follow.

terminal_tool() applies in tools/terminal_tool.py:1334-1344. If a rollout touches a file tool first, the environment is created directly in the shared cwd instead of a hermes-<task>-* subdirectory, so parallel local rollouts can still clobber each other's files. I reproduced that on this PR head by calling read_file_tool(..., task_id='taskB') first: the env cwd stayed . and _task_workdirs never got an entry for taskB.

…doffs The respawn guard's 'active_pr' check correctly prevents duplicate PR creation when a worker is respawned on a task that already has a PR URL in its comment history. But the same signal misfires for review-drain workflows: when an author blocks a task with 'review-required: ...' after posting the PR URL in a comment, the dispatcher must spawn a reviewer worker on the same task. The PR URL in comments is the handoff payload, not a duplicate-PR risk. Observed today on jetminds board: t_b522b69c (PR NousResearch#19) and t_509f152c (PR NousResearch#17) both looped through respawn_guarded:active_pr → jm-scan-drift re-block → routing fire → respawn_guarded:active_pr. The block_message accumulated three '[auto-reblocked by jm-scan-drift after drift detected]' bracket-suffixes before the loop was caught. Fix: introduce _review_required_handoff_active(conn, task_id) — a narrow predicate that reads the task's most-recent 'blocked' event's reason payload and returns True iff it starts with 'review-required:'. check_respawn_guard consults the predicate; when active, the active_pr branch is short-circuited and the spawn proceeds. The exception is scoped to the single most-recent blocked event, not a substring scan of full history. Once the reviewer drains and a 'completed' event lands after the block, subsequent re-spawns revert to the normal active_pr behavior (verified by test_respawn_guard_review_exception_does_not_leak_past_completion). Tests: 6 new (review-exception suppress, non-review still guards, exception expires post-completion, fresh-task baseline, prefix-only match, leading-whitespace tolerance). 21/21 respawn-guard tests pass; 164/164 test_kanban_db.py file passes. No upstream behavior changed for non-review-drain workflows. Refs: substrate task t_ee014b80 (engineering-lead, 2026-05-21) JetMinds-local; per hermes-fork-patches discipline
