start-issue

start-issue is a skill for Claude Code, Codex from nimble-giant/nimble-mold. It costs 34 tokens per session (696 once invoked), scanned A, original, Apache-2.0.

A workflow for starting development from a GitHub issue or a local plan file. A GitHub issue is a repository task or bug report with requirements and acceptance criteria.

In plain words
What is it for?
Use it to fetch an issue by number or URL, or choose a plan from the plans directory, then begin implementation and use its context for commits.
Why use it?
It turns the issue or plan into a focused task list and keeps the implementation tied to the stated requirements.

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

start-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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Start Issue

Fetch a {{scm.provider}} issue and begin implementation.

Usage

/start-issue <issue-number>
/start-issue <issue-url>
/start-issue --local <filename>
/start-issue --local

Flags

  • --local [filename]: Read from a local markdown file in the plans/ directory instead of fetching a {{scm.provider}} issue. If filename is omitted, list available plans and prompt the user to choose one.

Examples

  • /start-issue 1234 - Start work on issue #1234
  • /start-issue {{scm.base_url}}/your-org/your-repo/issues/1234 - Start work using full URL
  • /start-issue --local feat-web-add-control-family-status-card - Start work from a local plan file
  • /start-issue --local - List available local plans and choose one

Workflow

When this command is used:

GitHub Mode (default)

  1. Fetch the issue details using {{issue.view}}

  2. Create a todo list with tasks derived from the issue requirements

  3. Begin implementation following the issue requirements and acceptance criteria

  4. Use issue context to inform commit messages and implementation approach

Local Mode (--local flag)

  1. Resolve the plan file:
    • If a filename was provided, look for plans/<filename>.md (.md extension may be omitted)
    • If no filename was provided, list all *.md files in the plans/ directory and ask the user to choose one
  2. Read the local plan file and use it as the issue specification
  3. Create a todo list with tasks derived from the plan requirements
  4. Begin implementation following the plan's requirements and acceptance criteria
  5. Use the plan filename to inform commit messages in place of an issue number

Scope Boundaries

IMPORTANT: Stay focused on the specified issue ONLY.

  • Do NOT search for, fetch, or work on related issues, sub-issues, parent issues, or adjacent issues
  • Do NOT follow #XXXX references in the issue body to other issues
  • Do NOT use {{issue.list}} or {{issue.search}} to discover other issues
  • If the issue description mentions other issues for context, note them but do NOT expand scope to include their requirements
  • All work should be scoped strictly to what the specified issue describes

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.
