Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is vlad-ryzhkov/ai-context-engineering-for-qa's own configuration. It tells Claude Code how to work on ai-context-engineering-for-qa itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-context-engineering-for-qa configures →

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-markdown 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 today.

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 Markdown Lint Skill

Fix all markdownlint errors in .md files across the repository.

Rules

  • Only fix formatting issues
  • Do not change content meaning
  • Do not add tables or restructure sections
  • Do not rewrite or rephrase text

Steps

  1. Auto-fix what's possible:

    npx markdownlint-cli --fix "**/*.md" --ignore node_modules --ignore ".gradle" --ignore build --ignore audit
    
  2. Re-run to find remaining issues:

    npx markdownlint-cli "**/*.md" --ignore node_modules --ignore ".gradle" --ignore build --ignore audit
    
  3. Fix remaining errors manually using Edit tool (line length, heading levels, inline HTML)

  4. Verify: re-run step 2, expect zero errors

Gardener: If you noticed rule drift or improvements during this run, briefly note it here.

Changes

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.
