toolkit

toolkit is a skill for Claude Code from notque/vexjoy-agent. It costs 21 tokens per session (2,948 once invoked), scanned A, original, MIT.

A toolkit-management guide for creating, testing, comparing, composing, and improving skills and agents. It also maintains routing rules and generates CLAUDE.md, a file that records instructions for coding-agent work.

In plain words
What is it for?
Use it to scaffold skills or agents, run evaluations and comparisons, combine skills into pipelines, update routing tables, improve the toolkit, or create CLAUDE.md.
Why use it?
It organizes the lifecycle of agent add-ons so they can be created, evaluated, routed, and updated consistently.

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

toolkit 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 20d 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.

The opening of the file, as written. The whole thing — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Toolkit

Nine modes covering the full toolkit lifecycle: creating and improving skills and agents; evaluating agents; maintaining routing tables; generating CLAUDE.md; composing multi-skill DAGs; and running the evolution loop. Classify the request and follow the matching section.

Create Skill

Phases: INTENT -> DRAFT -> TEST -> REGISTER

  1. Capture intent. What should the skill do? When should it trigger? What output? Are outputs objectively verifiable (code, data) or subjective (writing, design)?
  2. Duplicate check. Run grep -i "<domain>" skills/*/SKILL.md to check existing coverage. If an umbrella skill covers the domain, add a reference file instead.
  3. Write SKILL.md. Follow references/skill-creator/skill-template.md for frontmatter structure. Apply Dense-Complete Writing standard. Frontmatter must include: name, description, routing (triggers, not_for, category, pairs_with), allowed-tools.
  4. Test. Try 3 should-trigger, 2 should-not-trigger, and 2 near-miss prompts with the skill loaded. Revise the SKILL.md until routing and output are right.
  5. Register. Run python3 scripts/generate-skill-index.py to update routing.

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.
