fix-issue

fix-issue is a skill for Claude Code, Codex from yu-iskw/coding-agent-fabric. It costs 31 tokens per session (629 once invoked), scanned A, original, Apache-2.0.

A workflow for fixing a numbered GitHub issue from investigation through implementation, testing, and pull-request creation. GitHub issues are tracked reports of bugs, tasks, or requested changes.

In plain words
What is it for?
Reading an issue, researching the relevant code, creating a fix branch, implementing the smallest suitable change, adding tests, and preparing a pull request.
Why use it?
It gives the agent a repeatable path from understanding the report to verifying the fix, reducing the chance of changing unrelated code or missing a regression test.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fix-issue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Fix GitHub Issue

Purpose

A complete workflow for fixing GitHub issues from understanding the problem to creating a pull request.

Arguments

  • $ARGUMENTS: GitHub issue number (e.g., 123 or #123)

Workflow

1. Understand the Issue

gh issue view $ARGUMENTS

Analyze:

  • What is the reported problem?
  • What is the expected behavior?
  • What is the actual behavior?
  • Are there reproduction steps?

2. Research the Codebase

Search for relevant code:

# Search for keywords from the issue
grep -r "keyword" src/

# Find related files
find . -name "*.ts" | xargs grep -l "relatedTerm"

Understand:

  • Which files are involved?
  • What is the current implementation?
  • Where does the bug originate?

3. Create Feature Branch

git checkout -b fix/issue-$ARGUMENTS-<brief-description>

4. Implement the Fix

Apply the minimum necessary change to resolve the issue:

  • Fix the root cause, not symptoms
  • Don't refactor unrelated code
  • Keep changes focused and reviewable

5. Add/Update Tests

Create tests that:

  • Reproduce the original bug (should fail without fix)
  • Verify the fix works (should pass with fix)
  • Cover edge cases

6. Verify the Fix

Run the verification cycle:

pnpm lint
pnpm test
pnpm build

Or invoke the verifier subagent for comprehensive validation.

7. Commit Changes

git add <specific-files>
git commit -m "fix(scope): brief description

Fixes #$ARGUMENTS"

8. Create Pull Request

git push -u origin HEAD

gh pr create --title "fix(scope): description" --body "$(cat <<'EOF'
## Summary

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
