skills CLAUDE.md

skills CLAUDE.md is an instructions file for coding agents from marimo-team/skills. It costs 151 tokens per session, scanned A, original, Apache-2.0.

An instruction file for Claude Code projects that use the marimo-team skills repository. It documents shared skill references and how copied reference files are kept in sync.

In plain words
What is it for?
Use it when maintaining the skills repository, especially after editing shared anywidget guidance and needing to synchronise its dependent copies.
Why use it?
It prevents related skill copies from becoming inconsistent after a shared source file is changed.

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.

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

skills 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 5d 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.

What it actually says

Skills Repository

Shared references

Some skills include reference copies of other skills' content so they work standalone. The source of truth for shared content lives in the original skill's SKILL.md.

Current shared references:

Source Copied to
skills/anywidget/SKILL.md skills/marimo-notebook/references/ANYWIDGET.md
skills/anywidget/SKILL.md skills/implement-paper/references/anywidget.md

After editing skills/anywidget/SKILL.md, run:

make sync

This copies the source file to all dependent locations. See the Makefile for details.

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.
