ci(#6462): add retry with backoff to eval setup-fixture.sh - #6465
Conversation
setup-fixture.sh performs multiple network-dependent GitHub API calls (gh repo create, git clone, git push, gh issue create, gh pr create) under set -euo pipefail with no retry logic. With parallelism: 4 in eval.yaml, transient API failures cause instant 4-second crashes that cascade into misleading scoring regressions in functional tests. Add a retry_cmd wrapper (3 attempts, exponential backoff at 2s/4s/8s) around all network operations. All diagnostic output goes to stderr to prevent stdout contamination in command substitutions per docs/contributing/shell-scripting.md. The git clone call uses a retry_clone helper that removes the target directory between attempts so partial clones don't block retries. Add setup-fixture-test.sh with unit tests for retry_cmd: verifies success, failure after max attempts, retry-then- succeed, stdout cleanliness, and stdout pass-through. Note: pre-commit could not run (sandbox network restriction blocked hook environment setup). lint-eval-cases could not fully run (yq not available in sandbox). Shell syntax validation (bash -n) passed. Closes #6462

Quality assessment
Triage quality: Strong. Correctly identified that setup-fixture.sh lacks retry logic for network-dependent GitHub API calls under set -euo pipefail with parallelism: 4.
Code quality: Good with minor issues. The retry_cmd wrapper is well-structured and follows the repo's shell scripting conventions (stderr-only diagnostics). Two minor quality gaps: (1) the function comment claims "2s/4s/8s delays" but the 8s delay is never used since the loop exits after the 3rd attempt — actual delays are 2s/4s only; (2) the test file was created without executable permission while all sibling scripts are 100755.
Review quality: High. The review agent identified 4 valid low-severity findings with zero false positives: stdout contamination risk in command substitutions, inaccurate documentation, 14-second test sleep time, and file permission mismatch. None were addressed before merge.
Evidence for existing issues
- Review agent should suggest /fs-fix for auto-fixable low-severity findings to prevent manual rework loops #5001 (review agent should suggest /fs-fix for auto-fixable low-severity findings): Two of the four findings (inaccurate comment, file permissions) are trivially auto-fixable. A fix agent dispatch for these would have improved code quality without human intervention.
- Review agent should flag when required checks couldn't run in sandbox #2108 (review agent should flag when required checks couldn't run in sandbox): The code agent's commit message notes "pre-commit could not run (sandbox network restriction blocked hook environment setup)" — the review agent did not flag this limitation.
- Define criteria for enabling review agent automated code approvals #6210 (define criteria for autonomous review approval): This PR is evidence that for CI/eval shell-script changes, the review agent provides equivalent or better coverage than human review (see proposal Add problem areas: Tekton pipeline review, migration path, multi-tenancy #2 below).
Proposals filed
- Code agent should match file permissions of sibling scripts when creating new files (in
fullsend-ai/agents) - Track autonomy readiness: review agent fully covered human review on CI eval shell-script change (in
fullsend-ai/fullsend)
