What is skills AGENTS.md?

Repository instructions for the FloLib Skills project, a collection of agent skills distributed through platform-specific marketplaces. They describe the repository layout, marketplace details, and how generated plugin packages are built and checked.

Use them when adding or updating skills, building platform packages, validating changes, or working with the Codex marketplace configuration.

They give coding agents the project context and rules needed to edit the right source files and keep generated marketplace packages consistent.

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	$0.01529	$0.01529
Opus 5.5	$0.00612	$0.00612
Sonnet 5.5	$0.00306	$0.00306
Haiku 4.5	$0.00153	$0.00153

Security

Grade A, and why

skills AGENTS.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/. Codex uses the root .agents/plugins/marketplace.json file and generated plugin packages under plugins/.

Marketplace

Marketplace name:

flolib-skills

Install from Codex:

codex plugin marketplace add wunamesst/skills

Local development:

node scripts/build-platforms.mjs
node scripts/validate.mjs
codex plugin marketplace add .

Plugin Structure

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

Current Skills

svg-diagram

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

Architecture: SKILL.md is a multi-step procedural handbook (type decision → canvas setup → color system → text sizing → per-type specs → dark mode → anti-overlap → checklist). Reference files are specialized sub-manuals:

Reference	Purpose
`references/sequence.md`	Sequence diagram spec + Y-coordinate lookup tables + example
`references/flowchart.md`	Flowchart spec + node sizing + decision diamond layout + example
`references/structure.md`	Structure diagram spec + nesting rules + example
`references/state-machine.md`	State machine spec + initial/final state templates + example
`references/timeline.md`	Timeline spec + event marker/card templates + example
`references/erd.md`	Mermaid.js ERD template with dark-mode and rounded-corner post-processing
`references/interactive.md`	HTML widget templates: stepper, slider, clickable nodes, animation
`references/illustrative.md`	Illustrative diagram rules: spatial metaphors, physical vs abstract themes
`references/embedded-styles.md`	Complete embedded CSS style block (color classes + dark mode) — backup reference

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.
