[aw] Code Scanning Fixer exceeded tool denial limit

Workflow Failure

Workflow: Code Scanning Fixer
Branch: main
Run: https://github.com/github/gh-aw/actions/runs/36801275611

Warning

Excessive Tool Denials: The Copilot SDK hit the max tool denial guardrail and stopped the session early (3/3).

This is a structured guardrail event (guard.tool_denials_exceeded) captured in events.jsonl.

How to fix this

The prompt attempted actions outside the workflow's allowed tools.

Update the workflow prompt and/or permissions so required actions are permitted:

The workflow code-scanning-fixer stopped because the Copilot SDK exceeded its tool denial threshold (3/3).

Please update the workflow so the prompt only uses tools permitted by the workflow tool policy.

Action Required

Assign this issue to an agent to debug and fix the issue.

Optimize token consumption

This failure was triggered by a guardrail limit (max-tool-denials). Use this prompt with any coding agent (GitHub Copilot, Claude, Gemini, etc.) to analyze token usage and reduce costs:

Debug with any coding agent

Use this prompt with any coding agent (GitHub Copilot, Claude, Gemini, etc.):

Debug the agentic workflow failure using https://raw.githubusercontent.com/github/gh-aw/main/debug.md

Manually invoke the agent

Debug this workflow failure using your favorite Agent CLI and the agentic-workflows prompt.

• Start your agent
• Load the agentic-workflows skill from .github/skills/agentic-workflows/SKILL.md or https://github.com/github/gh-aw/blob/main/.github/skills/agentic-workflows/SKILL.md
• Type debug the agentic workflow code-scanning-fixer failure in https://github.com/github/gh-aw/actions/runs/36801275611

Tip

Stop reporting this workflow as a failure

To stop a workflow from creating failure issues, set report-failure-as-issue: false in its frontmatter:

safe-outputs:
  report-failure-as-issue: false
