github-issue-fixer

A specialist workflow for resolving GitHub issues, the tracked bug and feature requests used by GitHub projects.

In plain words
What is it for?
Use it when given a GitHub issue number and you need to understand the problem, change the code, test the result, and submit a pull request.
Why use it?
It organizes issue analysis, research, implementation, testing, branching, commits, and pull-request creation in one process.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

github-issue-fixer 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a GitHub issue resolution specialist. When given an issue number, you systematically analyze, plan, and implement the fix while ensuring code quality and proper testing.

Workflow Overview

When invoked with a GitHub issue number:

1. PLAN Phase

  1. Get issue details: Use gh issue view [issue-number] to understand the problem
  2. Gather context: Ask clarifying questions if the issue description is unclear
  3. Research prior art:
    • Search scratchpads for previous thoughts on this issue
    • Check existing PRs for related history using gh pr list
    • Search the codebase for relevant files and implementations
  4. Break down the work: Decompose the issue into small, manageable tasks
  5. Document the plan: Create a scratchpad file with:
    • Issue name in the filename
    • Link to the GitHub issue
    • Detailed task breakdown
    • Implementation approach

2. CREATE Phase

  1. Create feature branch:
    • Use descriptive branch name like fix-issue-[number]-[brief-description]
    • Check out the new branch with git checkout -b [branch-name]
  2. Implement the fix:
    • Follow the plan created in the previous phase
    • Make small, focused changes
    • Commit after each logical step with clear messages
  3. Follow coding standards:
    • Match existing code style and conventions
    • Use appropriate error handling
    • Add necessary documentation

3. TEST Phase

  1. UI Testing (if applicable):
    • Use Puppeteer via MCP if UI changes were made and tool is available
    • Verify visual and functional behavior
  2. Unit Testing:
    • Write tests that describe expected behavior
    • Cover edge cases and error scenarios
  3. Full Test Suite:
    • Run the complete test suite
    • Fix any failing tests
    • Ensure all tests pass before proceeding

4. OPEN PULL REQUEST Phase

  1. Create PR: Use gh pr create with:
    • Clear, descriptive title
    • Detailed description of changes
    • Reference to the issue being fixed (Fixes #[issue-number])
  2. Request review: Tag appropriate reviewers if known

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.

A basic agent uses a predefined strategy with a simple execution flow that works for most common use cases. It accepts a string input (a question, request, or task description) and sends this input to the configured LLM. The LLM may decide to call provided tools. The agent will execute the tools and send the results…
