Prevent Multi-Device Docs Tester from self-terminating during cleanup

[Copilot]

The Multi-Device Docs Tester workflow was repeatedly failing with Claude exit code 143 after successful test execution. Failure logs show the agent invoking pkill -f during cleanup, which can terminate its own process and exhaust harness retries.

• Root cause addressed

  • Removed pkill* from the workflow’s allowed Bash tool patterns in daily-multi-device-docs-tester.md so the agent cannot invoke self-destructive process-kill patterns.

• Cleanup behavior tightened

  • Updated cleanup instructions to explicitly require shared PID-file shutdown (kill $(cat /tmp/gh-aw/server.pid)) and prohibit pkill -f, aligning with the imported server lifecycle contract.

• Compiled workflow sync

  • Regenerated daily-multi-device-docs-tester.lock.yml so the runtime allowlist and prompt reflect the new restriction.

# before
tools:
  bash:
    - "kill*"
    - "pkill*"

# after
tools:
  bash:
    - "kill*"

Pull request overview

Prevents the Multi-Device Docs Tester workflow from self-terminating during cleanup by removing overly-broad process-kill capabilities and reinforcing PID-file-based shutdown.

Changes:

• Removed pkill* from the docs tester workflow’s allowed Bash tool patterns.
• Tightened cleanup guidance to require PID-file-based shutdown and forbid pkill -f.
• Regenerated compiled workflow lockfile(s) to reflect the updated allowlist/prompt.
