fix-issue

fix-issue is a skill for Claude Code, Codex from viknesh20-20/claude-code-tool-kit. It costs 40 tokens per session (517 once invoked), scanned A, original, MIT.

A workflow for taking a GitHub issue from description to tested code. A GitHub issue is a tracked bug, feature request, or improvement in a project.

In plain words
What is it for?
Use it to investigate an issue, create a dedicated branch, find the relevant code, implement the fix, update tests, and optionally create a pull request.
Why use it?
Issue work can stall when requirements, affected code, acceptance criteria, and verification steps are unclear. It gathers that context, makes a focused change, and checks for regressions.

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.

What it actually says

Fix GitHub Issue

Fetch Issue Details

!gh issue view $1 2>/dev/null || echo "Usage: /fix-issue <issue-number> — requires gh CLI authenticated"


Workflow

Step 1: Understand the Issue

  1. Read the issue title, description, labels, and comments
  2. Identify: Is this a bug fix, feature request, or enhancement?
  3. Determine acceptance criteria — what does "done" look like?
  4. Note any linked issues, PRs, or referenced files

Step 2: Find Relevant Code

  1. Search the codebase for files/functions mentioned in the issue
  2. Trace the code path related to the reported behavior
  3. If it's a bug: try to reproduce the conditions mentally by reading the code
  4. Identify the minimal set of files that need to change

Step 3: Create a Branch

git checkout -b fix/issue-<number>-<short-description>

Step 4: Implement the Fix

  1. Make the smallest change that addresses the issue
  2. Follow existing code patterns and conventions
  3. Add or update tests to cover the fix
  4. Ensure no regressions in adjacent functionality

Step 5: Verify

  1. Run existing tests for the affected area
  2. Run the new tests
  3. Review your own diff: git diff
  4. Check for unintended changes

Step 6: Commit and PR

  1. Stage changes: git add <files>
  2. Commit with reference: git commit -m "fix: <description> (#<issue-number>)"
  3. Push: git push -u origin <branch>
  4. Create PR: gh pr create --title "Fix #<number>: <title>" --body "Closes #<number>"

Rules

  • Always reference the issue number in commits and PR
  • Don't scope-creep — fix only what the issue describes
  • If the issue is unclear, list your assumptions before implementing
  • If the fix requires architectural changes, flag it and discuss before proceeding

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.
