Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.07460 | $0.07460 |
| Opus 5 | $0.03730 | $0.03730 |
| Sonnet 5 | $0.01492 | $0.01492 |
| Haiku 4.5 | $0.00746 | $0.00746 |
Grade A, and why
claude-code-kit CLAUDE.md 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 2d 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 — 491 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Universal Claude Code toolkit — agents and skills for software development
Who this is for (design north-star)
This is a published plugin installed into other people's projects, not a tool for this repo alone. Every design decision is judged by: does this work in a consumer's environment — where the plugin's files live in the plugin cache (not the project cwd), where MCP servers may be absent or different, where hooks run on every session? A change that only works in this repo is a defect. (Concrete gate in the Contributing checklist.)
Interoperability is a first-class goal: the kit must compose cleanly with other
plugins (e.g., superpowers) and with whatever MCP servers the user has (memory MCPs,
search MCPs, private/company servers). Three rules: never assume a specific plugin/MCP
is present; never conflict with one that is; leverage generically when available
(e.g., recall-before-plan / remember-after-done if memory-style tools exist — fail-open
otherwise). Guidance lives in skills, never in agent tools: allowlists.

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.

claude-code-kit CLAUDE.md is an instructions file published in the GitHub repository This-HW/claude-code-kit (4 stars, last pushed 5d ago), licensed MIT. It adds 7,460 tokens to every session, about $0.0373 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
