genart-skill AGENTS.md

genart-skill AGENTS.md is an instructions file for Codex, OpenCode from camilleroux/genart-skill. It costs 763 tokens per session, scanned C, original, MIT.

A set of instructions for people editing the genart-skill repository, including its structure, writing rules, and testing expectations. The repository is a Claude Code plugin, which adds skills to Claude Code.

In plain words
What is it for?
Use it when changing the repository's documentation, reference sheets, plugin structure, or related code and tests.
Why use it?
It gives contributors shared rules for keeping platform references accurate, content concise, and the plugin's architecture intact. It also records details that a new editing session might otherwise miss.

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

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 C, and why

genart-skill AGENTS.md scanned grade C with 1 finding 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 today.

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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working on this repo

This repo IS a Claude Code plugin. Plugin users get skills/genart/SKILL.md through the plugin system — this file is only for sessions editing the repo.

Editorial rules (the ones a fresh session breaks in good faith)

  • Platform sheets are pointers, not copies. No library versions, no numeric values, no API field names in references/platforms/*.md — only the stable mental model, the doc URLs, and questions to ask those docs. Copied values go stale and are then worse than absent. Resist "just this one value". artpoint.md is the documented exception: Artpoint publishes no artist specification, so there is nothing to point at. Its delivery table carries real values with a provenance stamp and a date — keep both, and do not copy the pattern to a sheet whose platform has public docs.
  • fxhash is never mentioned (platform offline). Its concepts (mint-time params, preview trigger) are described neutrally in self-hosted.md.
  • Every reference sheet starts with <!-- Verified: YYYY-MM-DD --> — update it when you actually re-verify, not when you merely edit.
  • Concise: lists, tables, code — one sentence per idea. Platform sheets ~30–50 lines, transverse sheets ~50–120. No narrative prose.
  • Tone: defaults with legitimate counter-examples, never absolute rules. ethics.md is the only normative sheet.
  • All content in English.

Architecture invariants

  • Zero dependencies in the plugin. No package.json. Playwright lives in the artist's project; scripts print the install command when it is missing.
  • Scripts run in place via $CLAUDE_PLUGIN_ROOT, never copied into projects.
  • scripts/lib.mjs holds the shared contract encoding (launch flags, "render is done" wait, server). check.mjs and render.mjs must both use it — duplicating any of it lets the checker and renderer silently diverge.
  • tests/fixture/ is the sketch contract incarnate (defined in references/platforms/self-hosted.md). The broken variant is derived by sed in CI, never stored — see .github/workflows/ci.yml.
  • The version lives in .claude-plugin/plugin.json only. A release = bump it there + add a CHANGELOG.md entry (the update-communication channel).

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.
