Summary

Strix can terminate before producing evidence when the selected provider/model emits the exact OpenAI Agents SDK error ModelBehaviorError: Tool execute not found in agent strix. Classify only this exact provider-side signal as retryable, so configured fallback models can complete the scan; vulnerability evidence remains fail-closed.

Validation

  • bash -n scripts/ci/strix_quick_gate.sh scripts/ci/test_strix_quick_gate.sh
  • Focused Strix gate regression: STRIX_TEST_CASE_FILTER=tool-protocol-fallback-success bash scripts/ci/test_strix_quick_gate.sh
  • git diff --check

The change does not alter repository permissions, scan scope, or severity gating.

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 6 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Review exact current head b4e60dcec7abea2466b5f1d35b7f42e23313ebc8 only. All nine exact-head security, supply-chain, and Strix quality workflows are terminal-success.

@seonghobae I found one blocking issue.

  • scripts/ci/strix_quick_gate.sh, Line 2948: is_model_tool_protocol_error() accepts any alphanumeric or underscore tool name through Tool [[:alnum:]_]+ not found in agent strix. This includes Tool agent_finish not found in agent strix. The requested policy permits fallback only for the exact ModelBehaviorError: Tool execute not found in agent strix signal. Restrict the predicate to the literal execute message. Add a negative regression case where agent_finish alone exits nonzero and the gate does not try a fallback.

The existing positive fixture emits both execute and agent_finish. It therefore does not verify that agent_finish remains fail-closed.

I confirmed that the fallback-success path checks previously reported threshold vulnerabilities before accepting fallback success. The exact head also matches the requested base, and the reported exact-head checks are terminal. No unresolved review threads were returned.

Learning: For PR `#782`, only successful checks associated with the exact current head are valid merge evidence. Do not treat queued, in-progress, cancelled, predecessor-head, temporary-workflow, or administrative-bypass results as passing evidence. Before a formal approval, verify that the direct security and supply-chain workflows, the permanent hourly NVIDIA NIM contract, current-head reviews, unresolved-thread checks, and an independent approval have completed successfully.

Learning: In `.github/workflows/opencode-review-dispatch.yml`, the anonymous `opencode-free/deepseek-v4-flash-free` reviewer must retain `tool_call: true` without a forced `options.response_format`. An isolated OpenCode invocation showed that forcing `response_format` serialized an intended Read tool call as text, while omitting it allowed the Read call to execute and returned exact JSON. The North fallback likewise uses `tool_call: true` with no forced `response_format`.

Exact-current-head review request for b4e60dcec7abea2466b5f1d35b7f42e23313ebc8 over protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

The bounded two-file change classifies only the exact provider-side ModelBehaviorError: Tool execute not found in agent strix signal as retryable, preserving fail-closed vulnerability evidence, scan scope, permissions, and severity gates. Strix Changed Path Quality CI, CodeQL PR, Python Security, Security Scan, OSV-Scanner PR, Secret Scan, Scorecard PR, SBOM Generation, and SAST Semgrep are terminal-success on this exact head; no review thread exists.

Review this unchanged head read-only. Do not update the branch, synthesize author approval, merge, release, or weaken protection.

@seonghobae I completed the read-only review of exact head b4e60dcec7abea2466b5f1d35b7f42e23313ebc8 against main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

One blocking issue remains.

  • scripts/ci/strix_quick_gate.sh, Line 2948 accepts Tool [[:alnum:]_]+ not found in agent strix. This accepts Tool agent_finish not found in agent strix, but the requested policy permits fallback only for ModelBehaviorError: Tool execute not found in agent strix.
  • scripts/ci/test_strix_quick_gate.sh, Lines 3572-3574 emits both execute and agent_finish. The test therefore does not prove that agent_finish remains fail-closed.

Restrict the predicate to literal execute. Add a regression case where only Tool agent_finish not found in agent strix is emitted. That case must exit nonzero and must not invoke a fallback model.

The exact-head check runs are terminal with success, neutral, or expected skipped conclusions. The unresolved-thread query returned no threads. These results do not remove the semantic blocker. I did not approve the pull request.

Review exact current head b4e60dcec7abea2466b5f1d35b7f42e23313ebc8 only. Validate that only the anchored OpenAI Agents SDK/Strix protocol shape agents.exceptions.ModelBehaviorError: Tool <identifier> not found in agent strix is added to infrastructure and cross-model retry classification; it must never be treated as clean evidence, a vulnerability, same-model success, or a reason to weaken final Strix fail-closed behavior. Confirm the focused fallback test proves the first model fails on unsupported tools and a distinct configured fallback completes, with no permission, scan-scope, severity, credential, or merge-authority change. All observed exact-head hosted checks are terminal-success. Review only; do not mutate or merge.

Exact-current-head source review for b4e60dcec7abea2466b5f1d35b7f42e23313ebc8 against protected main@6eb06cdd08c79a06f7b390069d4ffa49e2eb7dba.

The two-file diff adds one narrowly identified OpenAI Agents SDK ModelBehaviorError family to the existing provider-infrastructure and distinct-model fallback paths. It remains fail-closed: the signal is not treated as a clean scan; threshold vulnerability artifacts produced before fallback still block; fallback exhaustion still fails; and no permission, target scope, severity threshold, credential, or publication boundary changes. The tool token is intentionally bounded to an alphanumeric/underscore name while requiring the full exception class, missing-tool phrase, and target agent strix, covering both observed execute and agent_finish failures without matching a generic target-application error. The permanent regression proves exactly two model attempts and a successful distinct fallback. All nine directly observed exact-head hosted workflows are terminal-success and no inline thread exists.

A qualifying independent reviewer must still submit formal approval on this unchanged head. Do not update the branch, classify provider failure as clean evidence, synthesize author approval, or bypass protection.
