A GitHub issue workflow that takes a developer from assigned issue to implementation. GitHub is a service for hosting code, issues, and pull requests, which are proposed changes for review.

In plain words
What is it for?
Use it to fetch an issue and its comments, assign the issue, update the local main branch, choose a feature, fix, or documentation branch, and begin implementation. It can then offer to create a pull request with /gh-pr.
Why use it?
It gathers the issue's full context, prepares a branch, and organizes the work so important setup steps are less likely to be missed.

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

gh-start 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 9d 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.

Start Work on Issue #$ARGUMENTS

Complete workflow from issue assignment through implementation. Ends with option to create PR via /gh-pr or continue working.

Tool Usage: This workflow uses the AskUserQuestion tool for interactive dialogues at key decision points.

Phase 1: Setup

  1. Fetch the issue:

    gh issue view $ARGUMENTS
    
  2. Fetch all issue comments for full context:

    REPO=$(gh repo view --json nameWithOwner --jq '.nameWithOwner')
    gh api repos/$REPO/issues/$ARGUMENTS/comments --jq '.[] | "---\n**@\(.user.login)** on \(.created_at):\n\(.body)\n"'
    
  3. Assign the issue to yourself:

    gh issue edit $ARGUMENTS --add-assignee @me
    
  4. Ensure on latest main:

    git checkout main && git pull origin main
    
  5. Determine branch type - If ambiguous, use the AskUserQuestion tool:

    When issue type is unclear (could be feature or fix), ask:

    • Option 1: "feature/issue-{number}-{desc}" - New functionality
    • Option 2: "fix/issue-{number}-{desc}" - Bug fix
    • Option 3: "docs/issue-{number}-{desc}" - Documentation only
    git checkout -b {branch-name}
    
  6. Confirm setup with user before beginning implementation

Phase 2: Implementation

  • Work through the issue requirements systematically
  • Follow CLAUDE.md guidelines for content patterns
  • For plugin changes, ensure plugin.json and marketplace.json stay in sync
  • Review Markdown formatting for consistency

Phase 3: Quality Checks

  1. Verify all acceptance criteria in the issue are met

  2. Run plugin validation (if plugin files changed):

    ls plugins/*/  # Check plugin directories exist
    cat plugins/*/.claude-plugin/plugin.json  # Verify plugin.json valid
    
  3. Commit with conventional format:

    • feat: for features
    • fix: for bug fixes
    • docs: for documentation
    • refactor: for refactoring
    • chore: for maintenance

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.
