Debug test-coverage-improver workflow failure (run 21994653857)

[Claude]

Root Cause

Workflow failed due to transient Claude API error: missing finish_reason for choice 0. Agent ran for 7 minutes, successfully generated 344-line test file for validateCustomServerConfig, then hit API response validation error.

Secondary Issue

Sparse checkout (33% of files) prevented agent from writing test file to internal/ directory despite successful generation.

Evidence

• Agent completed coverage analysis and test generation before failure
• Test file created: /tmp/agent/validateCustomServerConfig_test.go (15+ test cases, proper testify usage)
• API time: 5m 20s, Session time: 7m 6s, Code changes: +81
• Safe-outputs log confirms permission errors accessing internal/ directory

Recommendation

1. API error: Likely transient - retry workflow
2. Sparse checkout: Add explicit checkout pattern in workflow:

   - uses: actions/checkout@v4
     with:
       sparse-checkout: |
         internal/
         go.mod
         go.sum

Agent logic is sound - both issues are environmental/configuration.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/github/gh-aw-mcpg/actions/runs/21994653857/logs
  • Triggering command: /usr/bin/curl curl -s -L -H Accept: application/vnd.github+json -H X-GitHub-Api-Version: 2022-11-28 REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
