ai-engineering-fluency: Skill for Claude Code

.claude/skills/create-issue/SKILL.md

create-issue is a skill for Claude Code from rajbos/ai-engineering-fluency. It costs 106 tokens per session (1,898 once invoked), scanned A, original, MIT.

A guide for preparing a well-scoped GitHub issue, a written request to fix or add something in a code repository.

In plain words
What is it for?
Use it to gather the goal and affected surfaces, map the work to code locations, identify tests, and check whether related apps or packages also need changes.
Why use it?
It prevents vague issues that leave the implementer to repeat the original research or miss affected parts of the product.

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

create-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 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.

Create Issue Skill

This skill is guidance only (no scripts). It describes how issues in this repo must be prepared before they are filed, so that whoever picks the issue up (a person or a coding agent) can start without re-doing the research.

When to Use This Skill

Use it whenever you are asked to create, file or write up an issue for this repository — features, bugs, improvements, tech debt. Do not file an issue from a one-line request without going through the steps below.

Step 1 — Understand what and where

Get the following from the user. Take what they already said; do not re-ask for it.

  • What should be implemented, fixed or changed, and why (the problem or the value).
  • Where it shows up: which surface(s) — VS Code extension, CLI, Visual Studio, JetBrains, desktop app, sharing-server, copilot-app canvas, docs/scripts — and which view/tab/command if it is UI.
  • For bugs: steps to reproduce, expected vs. actual, versions/editor involved.

If any of this is unclear, ambiguous or you detect a gap (e.g. the request names a view but not what data it should show, or it is unclear whether other surfaces should get it too), ask the user before continuing. Ask concise, specific questions; batch them in one message. Prefer a recommendation ("I assume X, correct?") over open-ended questions. If the user cannot answer, record the open question in the issue instead of guessing.

Step 2 — Investigate the codebase

Before writing anything, look at the code. Do not describe changes from memory.

  • Start from AGENTS.md (repo structure, sub-project instructions) and the matching .github/instructions/*.instructions.md.
  • If .graphify-agent/graph.json exists, query it for structural questions (callers, blast radius), e.g. GRAPHIFY_OUT=.graphify-agent graphify query "<question>" (or pass --graph .graphify-agent/graph.json). Ignore any local graphify-out/ directory (stale, not the CI graph); if the graph is missing, search with grep/glob.
  • Check docs/ (especially docs/features/, docs/adr/, docs/FLUENCY-METRICS-SCHEMA.md, docs/TRACKABLE-DATA.md) for existing design decisions that apply.
  • Search existing open and recently closed issues/PRs (gh issue list --state all --search "<keywords>", gh pr list --state all --search "<keywords>") to avoid duplicates; link related ones instead of duplicating.

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.
