Problem

When the claude-agent-sdk raises a bare Exception with "Claude Code returned an error result: <subtype>" or the "Check stderr output for details" placeholder, the canvas showed only the generic "Agent error (Exception)" message. The actual user-actionable reason (rate-limit reset time, auth failure, etc.) was invisible without manual SSH + docker exec probing.

Fix

In the non-retryable error path, probe the CLI directly via _probe_claude_cli_error() and pass the captured stdout to sanitize_agent_error(..., stderr=probed) so the user sees the real failure reason.

Before

Agent error (Exception) — see workspace logs for details.

After

Agent error (Exception): You've hit your weekly limit · resets 6pm (UTC)

Change

  • claude_sdk_executor.py: probe CLI on SDK-swallowed error subtypes and forward to sanitize_agent_error(stderr=...)

Fixes #46

[Cross-review per CTO PARALLELIZE — CR2 verdict via PM relay, codex-GITEA_TOKEN gap core#2128/cp#444 workaround]

REQUEST_CHANGES on PR #79 (template#46 — surface real CLI error)

Repo: molecule-ai/molecule-ai-workspace-template-claude-code. Head: f4eec8b.

Findings:

  1. No regression tests for swallowed CLI stderr propagation OR normal path despite adapter behavior change. Need: tests covering (a) sad path — error stderr propagates to user-facing message, (b) happy path — normal output unaffected.

  2. Scope creep beyond template#46. PR includes unrelated .gitea/workflows/ci.yml aggregate hardening AND Dockerfile fail-closed install changes. Either split into separate PRs OR add justification linking them to template#46 root cause.

  3. CI RED on head f4eec8b: verify-providers-projection / Regenerate projection, fail on drift, assert registry subset template (pull_request) is FAILING. Must be GREEN before merge — likely related to scope-creep CI aggregate changes.

Good points (preserve in body):

  • Executor change directionally correct + preserves sanitize_agent_error path ✓
  • CI aggregate hardening is gate-honest in principle (would fit internal#780 work IF split out) ✓

migrate: use new_response_message helper (threads task_id/context_id) f3f078b2c6 
Replace direct `new_text_message` + ad-hoc Message construction with the canonical `new_response_message(context, text, files=...)` helper added in molecule-core PR #2271. Threads task_id/context_id back to the platform's a2a proxy uniformly with every other adapter.

The Python adapter audit (test_adapter_logging.py) pins the
adapter.py side, but the entrypoint shell function fires earlier and
twice (pre-gosu + post-gosu). When the SDK import wedge keeps the
adapter from running at all, the shell emission is the operator's
only visibility into the boot env.

Eight new tests cover:
- env NAME=set / env NAME=unset shape for every audited var
- value-leak guard: secret strings never appear in output
- WORKSPACE_ID + PLATFORM_URL passthrough by value (not secret)
- <unset> fallback for missing platform identifiers
- uid/gid line shape (used to verify the privilege drop)
- dated boot banner shape (used to count restarts in a crash loop)
- cross-file gate: shell for-loop names == fixture tuple, mirroring
  test_audit_env_list_matches_entrypoint_sh's adapter.py↔shell gate

Strategy: regex-extract the function body from entrypoint.sh and run
it in a fresh /bin/sh with controlled env. We never source the whole
entrypoint because it would chown /workspace and exec molecule-runtime.

Closes the gap from task #251 (follow-up to PR #32 boot-debug logging).

fix(tests): stub new_response_message in molecule_runtime helpers 18e8ae1072 
claude_sdk_executor.py imports new_response_message from
molecule_runtime.executor_helpers (added in PR #16,
migrate/use-new-response-message). The two test files that import
the executor stub a slimmed-down molecule_runtime.executor_helpers
module to avoid pulling the real wheel in CI — but the stub list
was never updated to include new_response_message, so every test
that loads the executor crashes at import:

  ImportError: cannot import name 'new_response_message' from
  'molecule_runtime.executor_helpers' (unknown location)

Add the same `_ensure_attr(helpers, "new_response_message", ...)`
line to both stub bundles. Now matches the public symbol surface
the executor needs at module load.

Was failing every push on main since PR #16 merged.

fix(tests): stub new_response_message in molecule_runtime helpers
fix(adapter): load providers from template config.yaml, not /configs 8404cf9a17 
The platform provisioner writes /configs/config.yaml with only
runtime/model/name — providers are a TEMPLATE concern and ship in
the template repo's own config.yaml (cloned to /opt/adapter/ at
provision time). _load_providers was only reading from /configs
and silently falling back to _BUILTIN_PROVIDERS (oauth +
anthropic-api), so every MiniMax/GLM/Kimi/DeepSeek model id
resolved to anthropic-oauth and the workspace died at first LLM
call with "Not logged in. Please run /login".

Fix: prefer the template-bundled config.yaml (next to adapter.py
via os.path.dirname(__file__)). Per-workspace config.yaml stays
as a fallback so operators on private deployments can override
the providers list. Builtins stay as the final fallback.

Caught by SSH'ing into a debug workspace on 2026-05-04 — the cron
canary masked this bug because it used direct-Anthropic until the
2026-05-03 migration to MiniMax (PR #2710 in molecule-core).

Includes 4 regression tests pinning the load order:
  - template wins when workspace config has no providers section
  - MiniMax-M2.7-highspeed routes to minimax provider end-to-end
  - per-workspace override honored when template config absent
  - builtins fallback when neither config exists

The new tests fail on the pre-fix code (verified by stashing the
adapter.py change and re-running) — they catch the actual silent
fallback rather than just structural shape.

test: isolate template config in _load_providers parsing tests cd1e488769 
The 5 _load_providers parsing tests in test_adapter_prevalidate.py
write a custom per-workspace config.yaml and assert against its
contents. Post-fix, _load_providers prefers the template-bundled
config.yaml (next to adapter.py) over the workspace one, so those
tests broke against the real shipped template registry.

Add a _isolate_template_config helper that monkeypatches
os.path.dirname in the adapter module's namespace so the template
lookup falls through to the per-workspace candidate. Each affected
test now creates a fake-template / workspace tmp_path pair and
calls the helper.

Test intent is unchanged — they still pin the per-workspace YAML
parsing contract (per-entry isolation, malformed-YAML fallback,
string-vs-list coercion, missing-name handling). They just now
exercise that contract via the per-workspace fallback path
instead of the template path.

Merge pull request #37 from Molecule-AI/fix/load-providers-from-template-config ed3afb10a2 
fix(adapter): load providers from template config.yaml, not /configs
fix(adapter): check /opt/adapter/config.yaml as canonical providers source 47b74ea479 
PR #37 added a template-bundled lookup using
``os.path.dirname(os.path.abspath(__file__))`` and verified the fix
on a workspace whose adapter.py was patched in-place. But the
platform's EC2-host install path
(molecule-controlplane ec2.go:2091) copies adapter.py into the
venv's site-packages dir:

    cp /opt/adapter/*.py /opt/molecule-venv/lib/python3.12/site-packages/

The host install does NOT set ``PYTHONPATH=/opt/adapter``, so site-
packages wins on import — ``__file__`` resolves to the venv path,
which has NO adjacent config.yaml. Same silent fallback to
``anthropic-oauth`` and same "Not logged in. Please run /login"
crash as the original PR #37 incident.

Verified on 2026-05-04 11:08Z: a fresh-provisioned MiniMax workspace
(cloned from main of this repo POST-PR-#37) showed the exact same
boot banner — ``provider=anthropic-oauth`` — because the venv-
installed adapter.py couldn't find its sibling config.yaml.

Fix: add the canonical install path
``/opt/adapter/config.yaml`` as the first lookup candidate.
This is invariant across both Docker (mounted /app→/opt/adapter)
and EC2-host (cloned by ec2.go) install paths. The ``__file__``
candidate stays as a dev/test fallback; the per-workspace yaml
remains as an operator-override path; builtins as final fallback.

Includes a regression test
(``test_load_providers_uses_canonical_path_when_file_dir_is_site_packages``)
that simulates the EC2-host install layout — ``__file__`` in a fake
site-packages dir without config.yaml, canonical path with the
registry — and pins ``MiniMax-M2.7-highspeed`` → ``minimax``
provider routing. Verified the test fails on the pre-this-PR code
(AttributeError on the missing ``_CANONICAL_ADAPTER_DIR`` constant).

Existing parsing tests in test_adapter_prevalidate.py +
test_provider_routing.py monkeypatch ``_CANONICAL_ADAPTER_DIR``
alongside ``os.path.dirname`` so they remain robust on CI runners
that happen to have a populated /opt/adapter dir.

Follow-up: also worth setting ``PYTHONPATH=/opt/adapter`` in the
provisioner env so Python imports adapter from /opt/adapter
directly (instead of relying on the site-packages copy). That's a
molecule-controlplane PR; this template-side fix makes the adapter
robust against any provisioner-side import-path layout.

fix(adapter): check /opt/adapter/config.yaml as canonical providers source
adapter: hoist import yaml out of _load_providers loop 7a7068473b 
Pure cleanup — yaml is already a transitive dep via
molecule-ai-workspace-runtime, and _load_providers ran the
import inside the candidate-iteration loop. Moving it to module
scope makes the loop body show only what's actually different
between iterations (yaml_path).

No behavior change. Closes #39.

fix(adapter): surface real CLI error message to user when SDK swallows it 605f94b734 
When the claude-agent-sdk raises a bare Exception with
\"Claude Code returned an error result: <subtype>\" or the
\"Check stderr output for details\" placeholder, the canvas previously
showed only the generic \"Agent error (Exception)\" message.

Now we probe the CLI directly via _probe_claude_cli_error() and pass
the captured stdout to sanitize_agent_error(..., stderr=probed) so the
user sees the actual actionable reason (e.g. rate-limit reset time)
instead of having to SSH into the container to find out why.

When _run_query succeeds, the probe must not fire and stderr= must
stay None. This closes the CR2 gap: the existing tests only covered
exception paths, leaving the happy path unguarded.

CR2 scope-creep fix applied — PR split into 3 focused PRs.

Per PM dispatch, the original PR mixed template#46 (CLI error surfacing) with unrelated CI aggregate hardening (#76 #51) and Dockerfile fail-closed changes (#75). I have split them as follows:

  1. This PR (#79) — now contains ONLY the adapter fix (claude_sdk_executor.py) + regression tests (tests/test_cli_error_probe.py), including the new happy-path guard requested in Finding 1.

  2. PR #81 — CI aggregate hardening (fix/ci-aggregate-hardening): hard-gates T4 + adds tests to validate.needs.

  3. PR #82 — Dockerfile fail-closed install (fix/dockerfile-fail-closed-install): removes 2>/dev/null || true masking + adds command -v claude verification.

Finding 3 (CI RED) investigation: verify-providers-projection failure is pre-existing on main (main push context also shows this job failing). It is not caused by the CI changes in this PR or the split.

Ready for re-review.
