What is skills CLAUDE.md?

Repository instructions for FloLib Skills, a collection of agent skills distributed through platform-specific marketplaces. It describes the canonical skill files, generated Codex packages, marketplace metadata, and development output.

Use it when developing skills, generating platform packages, updating marketplace metadata, or installing and testing skills locally.

Keeping source skills, generated packages, and marketplace entries aligned prevents users from installing outdated or incomplete versions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00510	$0.00510
Opus 5.5	$0.00204	$0.00204
Sonnet 5.5	$0.00102	$0.00102
Haiku 4.5	$0.00051	$0.00051

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 2mo 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.

Repository Purpose

This is the FloLib Skills repository: a multi-platform collection of agent skills distributed through platform-specific marketplace metadata.

Canonical skill sources live in skills/. Claude Code uses the root .claude-plugin/ files to install those canonical skill directories directly.

Marketplace

Marketplace name:

flolib-skills

Install from Claude Code:

/plugin marketplace add https://github.com/wunamesst/skills
/plugin install svg-diagram@flolib-skills
/plugin install poly-wiki@flolib-skills

Local development:

/plugin marketplace add .
/plugin install svg-diagram@flolib-skills
/plugin install poly-wiki@flolib-skills

Repository Layout

Do not edit generated copies under plugins/*/skills/ directly. Edit skills/<skill-name>/ and run:

node scripts/build-platforms.mjs
node scripts/validate.mjs

Current Skills

svg-diagram

Production-grade hand-written SVG diagram skill. Supports sequence diagrams, flowcharts, structure diagrams, state machines, timelines, ERDs, interactive HTML widgets, and illustrative diagrams.

poly-wiki

Knowledge-base compiler for ingesting raw materials, extracting reusable patterns, linting wiki structure, and querying archived knowledge.

Claude Code command prompts live in skills/poly-wiki/commands/.

Adding A Skill

Follow docs/main/flolib-skills-standards.md.

At minimum:

Add canonical source under skills/<skill-name>/.
Add the Claude marketplace entry in .claude-plugin/marketplace.json.
Add the Codex marketplace entry in .agents/plugins/marketplace.json.
Add plugins/<skill-name>/.codex-plugin/plugin.json.
Add the skill name to scripts/build-platforms.mjs and scripts/validate.mjs.
Run build and validation.

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.
