The “Redact secrets in logs” step can fail after the agent succeeds when a large artifact directory overflows the scanner’s call stack. This affects multiple workflows that share the redaction step.

  • Scanner: Replace recursive traversal and spread-based file-list appends with iterative traversal. Keep symbolic-link removal before artifact upload.
  • Regression coverage: Exercise discovery of 150,000 log files in a nested directory.

The unrelated skill edit removes explicit work-queue routing and should be restored.

What changed in this PR

Prevents stack overflow during large secret-redaction scans by using iterative file traversal.

Changes:

  • Replaces recursive traversal and spread appends with an explicit stack.
  • Adds regression coverage for 150,000 files.
  • Reorders a workflow-skill entry but inadvertently removes its routing instruction.
File Description
actions/​setup/​js/​redact_secrets.cjs Implements iterative scanning while retaining symlink removal.
actions/​setup/​js/​redact_secrets.test.cjs Tests large nested file discovery.
.github/​skills/​agentic-workflows/​SKILL.md Moves the work-queue entry but removes explicit routing.
