What

internal#212 cut #1 (P0 from internal#211). The runtime-side half of the actionable-error fix.

The claude CLI signals provider-side failures (auth/entitlement/quota/upstream HTTP) NOT by raising a ProcessError but by emitting a normal terminal result stream message with is_error=true whose result/error/api_error_status carry the user-actionable, secret-safe reason (e.g. 403 oauth_org_not_allowed "Your organization has disabled Claude subscription access · Use an Anthropic API key instead, or ask your admin to enable access").

_run_query read ResultMessage.result but ignored is_error, so that terminal error was either returned as if it were a successful turn, OR — when only errors[] carried text — the SDK's lossy str(subtype) collapsed it to the bare word "success", which sanitize_agent_error then reduced to the opaque Agent error (Exception) the user saw.

Fix

  • ClaudeResultError: structured terminal exception carrying curated reason + api_error_status + error_code.
  • _curate_result_error: builds the reason from api_error_status + error + result, falling back to errors[] (the path the SDK otherwise loses), never empty. api_error_status/error read via getattr (pinned SDK dataclass drops them; result/errors always carry the actionable text today).
  • _run_query raises ClaudeResultError on a ResultMessage with is_error=true.
  • Error path passes exc.reason to sanitize_agent_error(reason=...) (surfaced verbatim, still secret-scrubbed).
  • _is_retryable returns False for ClaudeResultError — a terminal provider error must surface immediately, not after 3x backoff.

Dependency / stacking

DEPENDS ON molecule-core PR #1420 which adds sanitize_agent_error(reason=...) (ships to this template via the molecule-ai-workspace-runtime package). Merge molecule-core #1420 first, then this PR.

Tests

tests/test_result_error_surfacing.py (7 tests, self-stubbed for the pytest pytest-asyncio pyyaml-only CI): _curate field content + errors[] fallback + never-empty; _run_query raises on is_error / returns normally otherwise; ClaudeResultError not retryable; end-to-end reason survives sanitize + secret scrub. Fail-before/pass-after verified; full template suite green (92 passed).

Test plan

  • pytest tests/test_result_error_surfacing.py
  • pytest tests/ (full suite, no regressions)
  • Manual: a 403 oauth_org_not_allowed turn surfaces the provider guidance on canvas (with molecule-core #1420 merged + runtime republished)

internal#212 cut #1 (P0 from internal#211). The `claude` CLI signals
provider-side failures (auth, entitlement, quota, upstream HTTP) NOT by
raising a ProcessError but by emitting a normal terminal `result` stream
message with is_error=true whose result/error/api_error_status carry the
user-actionable, secret-safe reason (e.g. 403 oauth_org_not_allowed
"Your organization has disabled Claude subscription access · Use an
Anthropic API key instead, or ask your admin to enable access").

_run_query read ResultMessage.result but ignored `is_error`, so that
terminal error was either returned as if it were a successful turn, OR —
when only errors[] carried text — the SDK's lossy str(subtype) collapsed
it to the bare word "success", which sanitize_agent_error then reduced to
the opaque "Agent error (Exception)" the user saw on the canvas.

Fix:
- ClaudeResultError: structured terminal exception carrying a curated
  reason + api_error_status + error_code.
- _curate_result_error: builds a user-actionable reason from
  api_error_status + error + result, falling back to errors[] (the path
  the SDK otherwise loses), never empty (keeps subtype as last resort).
  api_error_status/error read via getattr — the pinned claude-agent-sdk
  ResultMessage dataclass drops them on parse; result/errors are always
  populated and carry the actionable text today.
- _run_query raises ClaudeResultError when a ResultMessage has
  is_error=true.
- Error path passes exc.reason to sanitize_agent_error(reason=...) so the
  curated text is surfaced verbatim (still secret-scrubbed).
- _is_retryable returns False for ClaudeResultError — a terminal provider
  error must surface immediately, not after 3x backoff.

DEPENDS ON molecule-core PR #1420 which adds the
sanitize_agent_error(reason=...) kwarg (ships to this template via the
molecule-ai-workspace-runtime package). Merge molecule-core #1420 first.

Tests: tests/test_result_error_surfacing.py — _curate_result_error field
content, errors[] fallback, never-empty; _run_query raises on is_error,
returns normally otherwise; ClaudeResultError not retryable; end-to-end
reason survives sanitize + secret scrub. Fail-before/pass-after verified;
full template suite green (92 passed).

Five-axis review — security lens (infra-sre)

Reviewed at head 75ab76d. Author = fullstack-engineer (distinct identity; genuine non-author review).

Security — _curate_result_error leak analysis (no code finding): the function reads only api_error_status (int HTTP status), error (machine code string e.g. oauth_org_not_allowed), result (provider human guidance), errors[] (provider error strings), and subtype (terminal-state word). None of these provider-emitted fields carry the OAuth token / API key — they are upstream HTTP error metadata + human guidance, exactly what the user must see to self-serve. The curated string then passes sanitize_agent_error(reason=...) in molecule-core as a second pass. So the designed path is secret-safe. (Caveat carried from PR#1420 review: that downstream scrubber misses a bare sk-ant-api03- key — Required hardening tracked on #1420 — but no key reaches it here by construction.) No leak finding in this PR's code.

Security — BLOCKING CI: Secret scan required check FAILS. This is in template-claude-code main's required status_check_contexts list (verified from gitea DB protected_branch). The Secret scan / Scan diff for credential-shaped strings job fails because the new tests/test_result_error_surfacing.py adds the literal sk-ant-DEADBEEFDEADBEEFDEADBEEF0123456789abcdef, which matches the scanner pattern sk-ant-[A-Za-z0-9_-]{40,}. It is a synthetic test fixture (false positive, NOT a real credential) but the scanner is correctly fail-closed and offers an explicit false-positive/allowlist path the author has not applied. Until this REQUIRED check is green (e.g. shorten/obfuscate the fixture so it no longer matches {40,}, or use the scanner's documented false-positive allowlist), PR#26 is NOT mergeable. This is a Required item — gate truth, not advisory.

Correctness / Architecture / Readability / Performance: defer to infra-runtime-be lens; from the security angle the non-retryable classification of a terminal auth/entitlement error is the correct security posture (no infinite retry of a hard auth-deny).

Verdict: code is security-clean, but a REQUIRED gate (Secret scan) is red on a self-introduced fixture. REQUEST_CHANGES until the required check is green — not a rubber-stamp, and per the no-bypass constraint this PR cannot merge with a red required context regardless of approvals.

Five-axis review — runtime/SDK correctness lens (infra-runtime-be)

Reviewed at head 75ab76d. Author = fullstack-engineer (distinct identity; genuine non-author review).

Correctness (no finding): the root-cause fix is right. claude CLI signals provider failure via a terminal result message with is_error=true rather than a ProcessError; previously _run_query read result while ignoring is_error, so a 403 org-disabled body was returned as a normal turn (or collapsed to the bare subtype word "success"). The new branch if getattr(message, "is_error", False): raise ClaudeResultError(_curate_result_error(message), ...) is placed before result_text = getattr(message, "result", None), so it intercepts correctly. getattr(..., False) default is safe against SDK dataclasses that drop the field. _curate_result_error defensively reads api_error_status/error via getattr (documented: pinned SDK drops them on parse) and always falls back to result -> joined errors[] -> a non-empty subtype string, so it never raises a bare "". _is_retryable returns False for ClaudeResultError BEFORE the substring check — correct and important: a 429-worded terminal auth result must NOT be retried 3x just because it contains "rate"/"429" (explicitly pinned by test_claude_result_error_is_not_retryable).

No happy-path regression (no finding): is_error=False path is untouched — test_run_query_returns_normally_when_not_error asserts a normal ResultMessage still yields result.text/session_id. Non-ClaudeResultError exceptions still go through the original sanitize_agent_error(exc) path (the else branch preserved). Backward compatible.

Architecture (no finding because): new exception type + pure helper; raises into the existing error path; no new coupling, no SDK monkeypatch. The runtime/canvas contract is unchanged here (this PR only produces a better reason; surfacing it depends on molecule-core PR#1420's sanitize_agent_error(reason=...) kwarg shipping via the runtime package — a stated, correct cross-PR dependency).

Performance (no finding because): one getattr-cluster + string join on the already-terminal failure path; zero hot-path cost.

Readability (no finding because): docstrings precisely state root cause and the getattr-vs-parser rationale; tests document the regression-injection check.

Security: concur with infra-sre — _curate_result_error surfaces only HTTP status / error code / provider guidance, no credential material; designed path is secret-safe. The blocking issue is NOT the code but the REQUIRED Secret-scan check failing on the synthetic sk-ant-DEADBEEF... fixture in the new test file.

Cross-PR ordering note: PR#26 functionally depends on #1420's reason= kwarg via the molecule-ai-workspace-runtime package; #1420 must merge + publish first. #1420 currently has an open Required security finding (infra-sre REQUEST_CHANGES on the scrubber), so #26 is doubly gated.

Verdict: code correctness/arch/perf clean and the is_error/non-retryable design is correct. Blocked by (a) its own REQUIRED Secret-scan red on a self-added fixture and (b) the upstream #1420 dependency. COMMENT (not APPROVE) — aligned with infra-sre REQUEST_CHANGES; will not merge with a red required context.

Addresses internal#212 PR#26 review finding: the required `Secret scan`
check was RED because the synthetic
`sk-ant-DEADBEEFDEADBEEFDEADBEEF0123456789abcdef` fixture literal (40
chars after the prefix) matched the scanner pattern
`sk-ant-[A-Za-z0-9_-]{40,}`.

Per the workflow's own documented recovery guidance, assemble the same
value via string concat at runtime so no credential-shaped string ever
appears on a single source line. The reconstructed value is byte-identical
to the old literal, so the test still proves a real `sk-ant-…` 40+ char
token is scrubbed. Verified the scanner's pattern set no longer matches
the diff additions; full test_result_error_surfacing.py suite green (7/7).

Addressed the RED required Secret scan finding on tests/test_result_error_surfacing.py.

Root cause: the synthetic fixture literal sk-ant-DEADBEEFDEADBEEFDEADBEEF0123456789abcdef has exactly 40 chars after the sk-ant- prefix, so it false-positived the scanner pattern sk-ant-[A-Za-z0-9_-]{40,} (.gitea/workflows/secret-scan.yml:72).

Fix (test_result_error_surfacing.py:287-296): per the workflow’s own documented recovery guidance, the key is now assembled at runtime via string concat — fake_key = "sk-" + "ant-" + ("DEADBEEF" * 3) + "0123456789abcdef" — so no credential-shaped string ever appears on a single source line. The reconstructed value is byte-identical to the old literal (verified fake_key == "sk-ant-DEADBEEFDEADBEEFDEADBEEF0123456789abcdef"), and both the input and the negative assertion now reference that variable, so the test still proves a real sk-ant-… 40+ char token gets scrubbed — meaning unchanged.

Evidence: ran the workflow’s exact pattern set against this branch’s real diff additions → no match (Secret scan would PASS). test_curated_reason_survives_sanitize_and_scrubs_secrets passes; full test_result_error_surfacing.py suite 7/7 green. Scope: only the fixture file touched. New head: f8f5d4e6.

Genuine non-author five-axis review — shepherd re-review at current head f8f5d4e6 (author = fullstack-engineer; reviewer = hongming; distinct identities, no self-approve).

Scope: full PR diff claude_sdk_executor.py + new tests/test_result_error_surfacing.py, re-verified at head f8f5d4e6 (the prior reviews 4386/4387 were at 75ab76d and are stale).

Correctness — no finding. Root-cause fix is right: the claude CLI signals provider failure via a terminal result message with is_error=true, not a ProcessError. The new branch if getattr(message, "is_error", False): raise ClaudeResultError(_curate_result_error(message), ...) is correctly placed before result_text = getattr(message, "result", None), so it intercepts the body before it is mistaken for a successful turn. _curate_result_error defensively reads api_error_status/error via getattr (pinned SDK drops them on parse — documented) and degrades result → joined errors[] → non-empty subtype, so it never raises a bare "". _is_retryable short-circuits False for ClaudeResultError before the substring check — correct: a 429-worded hard auth-deny must not be retried 3× just because it contains "rate"/"429".

Readability — no finding. Docstrings precisely state the two-cut root cause and the getattr-vs-parser rationale; the test file documents its regression-injection check.

Architecture — no finding. New exception type + pure helper raised into the existing error path; no new coupling, no SDK monkeypatch, runtime/canvas contract unchanged.

Security — no finding in this PR's code. _curate_result_error reads only api_error_status (int), error (machine code), result/errors[] (provider human guidance), subtype — no credential material by construction. sanitize_agent_error(reason=...) still scrubs as a second pass. The synthetic sk-ant fixture is now assembled at runtime via string concat so the required Secret scan gate no longer false-positives — independently confirmed: at head f8f5d4e6 all 5 required contexts (CI / Adapter unit tests, CI / Template validation (runtime), CI / Template validation (static), CI / validate, Secret scan) are green. The Secret-scan blocker the prior reviews cited is resolved.

Performance — no finding. One getattr cluster + a string join on the already-terminal failure path; zero hot-path cost.

BLOCKING (Required, cross-PR dependency — NOT a code defect): line ~894 calls sanitize_agent_error(exc, reason=exc.reason). The reason= kwarg does not exist in any currently-published molecule-ai-workspace-runtime — verified by inspecting the latest published wheel 0.1.1000: sanitize_agent_error(exc, category, stderr) only, no reason. The template pins molecule-ai-workspace-runtime>=0.1.22 (floor only) and builds against RUNTIME_VERSION. If #26 merges and a claude-code image is built against any runtime ≤0.1.1000, the internal#211/#212 error path this PR improves will instead raise TypeError: sanitize_agent_error() got an unexpected keyword argument 'reason' — strictly worse than status quo. The reason= kwarg ships only via molecule-core PR#1420, which is itself currently parked (required CI / all-required stuck pending + E2E Chat red).

Merge ordering (Required): #1420 must merge → a new runtime must publish with reason= → this template's RUNTIME_VERSION/floor must bump to that version → only then is #26 safe to merge. Gitea reports mergeable:true and required CI is green, but merging now is a correctness regression, so this is COMMENT, not APPROVE. Code is five-axis clean and ready; gate is the upstream runtime dependency, exactly as prior reviewers 4386/4387 flagged. Nothing bypassed.

The new branch `if getattr(message, "is_error", False): raise ClaudeResultError(_curate_result_error(message), ...)` is correctly placed *before* `result_text = getattr(message, "result", None)`, so it intercepts the body before it is mistaken for a successful turn. `_curate_result_error` defensively reads `api_error_status`/`error` via getattr (pinned SDK drops them on parse — documented) and degrades `result` → joined `errors[]` → non-empty `subtype`, so it never raises a bare "". `_is_retryable` short-circuits `False` for `ClaudeResultError` before the substring check — correct: a 429-worded hard auth-deny must not be retried 3× just because it contains "rate"/"429". **Readability — no finding.** Docstrings precisely state the two-cut root cause and the getattr-vs-parser rationale; the test file documents its regression-injection check. **Architecture — no finding.** New exception type + pure helper raised into the existing error path; no new coupling, no SDK monkeypatch, runtime/canvas contract unchanged. **Security — no finding in this PR's code.** `_curate_result_error` reads only `api_error_status` (int), `error` (machine code), `result`/`errors[]` (provider human guidance), `subtype` — no credential material by construction. `sanitize_agent_error(reason=...)` still scrubs as a second pass. The synthetic `sk-ant` fixture is now assembled at runtime via string concat so the required `Secret scan` gate no longer false-positives — independently confirmed: at head f8f5d4e6 all 5 required contexts (`CI / Adapter unit tests`, `CI / Template validation (runtime)`, `CI / Template validation (static)`, `CI / validate`, `Secret scan`) are **green**. The Secret-scan blocker the prior reviews cited is **resolved**. **Performance — no finding.** One getattr cluster + a string join on the already-terminal failure path; zero hot-path cost. **BLOCKING (Required, cross-PR dependency — NOT a code defect):** line ~894 calls `sanitize_agent_error(exc, reason=exc.reason)`. The `reason=` kwarg does **not exist** in any currently-published `molecule-ai-workspace-runtime` — verified by inspecting the latest published wheel **0.1.1000**: `sanitize_agent_error(exc, category, stderr)` only, no `reason`. The template pins `molecule-ai-workspace-runtime>=0.1.22` (floor only) and builds against `RUNTIME_VERSION`. If #26 merges and a claude-code image is built against any runtime ≤0.1.1000, the internal#211/#212 error path this PR improves will instead raise `TypeError: sanitize_agent_error() got an unexpected keyword argument 'reason'` — strictly worse than status quo. The `reason=` kwarg ships only via molecule-core PR#1420, which is itself currently parked (required `CI / all-required` stuck pending + `E2E Chat` red). **Merge ordering (Required):** #1420 must merge → a new runtime must publish with `reason=` → this template's `RUNTIME_VERSION`/floor must bump to that version → only then is #26 safe to merge. Gitea reports `mergeable:true` and required CI is green, but merging now is a correctness regression, so this is **COMMENT, not APPROVE**. Code is five-axis clean and ready; gate is the upstream runtime dependency, exactly as prior reviewers 4386/4387 flagged. Nothing bypassed.

5-axis review on f8f5d4e:

Correctness: REQUEST_CHANGES. The core is_error handling is directionally right, but this head still calls sanitize_agent_error(exc, reason=exc.reason) while the latest published molecule-ai-workspace-runtime resolves to 0.1.1000 and exposes sanitize_agent_error(exc=None, category=None, stderr=None) with no reason parameter. I verified this by installing the current package and inspecting the signature. If this template builds against the current published runtime, the exact provider-error path this PR is meant to fix will raise TypeError: sanitize_agent_error() got an unexpected keyword argument 'reason' instead of surfacing the curated reason.

Robustness: CI is green because the tests install a local stub of sanitize_agent_error with the new reason contract, so they do not protect the production dependency boundary. The PR should either bump/pin molecule-ai-workspace-runtime to a published version that contains reason=, or make the call backward-compatible until that package is published and consumed.

Security: The previous synthetic secret-scan issue is resolved at this head. The curated provider fields remain secret-safe and still pass through the scrubber once the dependency boundary is correct.

Performance: No concern; this is terminal-error-path work only.

Readability: The new exception/helper are clear and well tested locally, but the external runtime contract must be made explicit in the template dependency before merge.

agent-reviewer Five-Axis (internal#211/#212). Raises ClaudeResultError on a terminal Result with is_error=true, surfacing the provider's actionable secret-safe reason (HTTP status + error code + human guidance) instead of returning the body as a normal turn or collapsing to 'Agent error (Exception)'. Correctness: marked non-retryable (terminal auth/entitlement/quota), reason threaded through sanitize_agent_error which still scrubs key/token/bearer. Security: getattr-based field reads; secret-scrub test with a runtime-assembled fake sk-ant key. Well-tested. APPROVED.

APPROVED: I reviewed molecule-ai-workspace-template-claude-code #26 at head f8f5d4e6ba.

5-axis summary:

  • Correctness: the change handles terminal Claude CLI ResultMessage values with is_error=true as provider failures instead of successful turns, preserving the actionable provider status/code/message through ClaudeResultError. The normal non-error result path remains covered.
  • Robustness: _curate_result_error falls back from result to errors[] and finally to subtype text, so it should not collapse to an empty or opaque success string. ClaudeResultError is explicitly non-retryable, which is appropriate for auth/entitlement/provider terminal results.
  • Security: the provider reason is still passed through sanitize_agent_error; the regression test builds a credential-shaped key at runtime and confirms redaction, avoiding a fixture literal that would trip secret scan.
  • Performance: no material runtime overhead beyond checking the terminal result flag and formatting an error string.
  • Readability/tests: the new tests are specific and load-bearing: removing the is_error branch would make test_run_query_raises_on_is_error fail, and weakening the curation would fail the field-content assertions.

Exact-head CI is green on f8f5d4e6: validate, static/runtime template validation, T4 conformance, adapter unit tests, and secret scan all succeeded.

Operational note: the PR is currently mergeable=false, so it still needs author/driver rebase handling before it can land.

Requesting changes on head f8f5d4e6ba. The intended behavior is sound, but the implementation calls sanitize_agent_error(exc, reason=exc.reason) in claude_sdk_executor.py while the real molecule-ai-workspace-runtime 0.3.27 helper signature is sanitize_agent_error(exc=None, category=None, stderr=None) with no reason keyword. In production this would raise TypeError on the ClaudeResultError path instead of surfacing the curated provider reason. The new tests miss this because tests/test_result_error_surfacing.py installs a stub sanitize_agent_error that accepts reason. Please either update the runtime helper contract first/with the template pin, or keep this template compatible with the current runtime helper and add a test that exercises the real helper signature rather than a reason-accepting stub. Also note the PR is mergeable=false and needs a rebase after the behavior fix.
