[aw] Code Scanning Fixer is missing required tool #65330
Description
Workflow Failure
Workflow: Code Scanning Fixer
Branch: main
Run: https://github.com/github/gh-aw/actions/runs/37129527280
Warning
Repeated Permission Denied: The agent was denied permission to run 1 command(s) and stopped retrying.
Denied Commands:
shell(python3 - <<'E' | shell(go build ./pkg/workflow/ && git diff --binary --no-ext-diff | wc -c) | shell(cat > /tmp/gh-aw/agent/pr.json <<'E'
How to fix this
The agent ran in non-interactive mode (--no-ask-user) and could not request permission at runtime.
To resolve repeated permission denied errors, update the workflow prompt to avoid these commands or use approved alternatives. Use the following prompt with any coding agent:
The agentic workflow code-scanning-fixer encountered repeated permission denied errors for these commands:
`shell(python3 - <<'E' | shell(go build ./pkg/workflow/ && git diff --binary --no-ext-diff | wc -c) | shell(cat > /tmp/gh-aw/agent/pr.json <<'E'`
Please update the workflow prompt so the agent:
1. Uses built-in tools (GitHub API, file read/write) instead of the denied shell commands
2. Or achieves the same goal through alternative approaches that do not require shell permission
Warning
Engine Failure: The copilot engine terminated unexpectedly.
