    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

shine 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 9d 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

Shine — Create an Interactive Explanation

Use this skill to start a new moonshine explanation. The user invokes it as $shine or $shine <topic> (anything after $shine is the starting topic; treat an empty topic as "start from scratch").

Workflow

  1. Load the moonshine skill first. Read ../moonshine/SKILL.md and follow its full workflow — story discovery is mandatory and comes before any code.
  2. Reference files live next to the moonshine skill:
    • ../moonshine/ARTICLE.md — single-file HTML scaffold, CSS foundation, layout patterns, series structure.
    • ../moonshine/VISUALS.md — D3 v7 visualization patterns, interaction, rendering decisions, iteration loop.
  3. Output location. Write the project to ~/.agent/moonshine/<kebab-case-project-name>/ as a self-contained index.html plus an optional data/ directory. Vanilla JS + D3 v7 only. No build tools, no frameworks.
  4. Story discovery is the gate. Do not skip to code. Ask the user about concept, audience, key insight, and progression of understanding, then checkpoint with "Here's what I think we're building..." before scaffolding.
  5. Iterate. Start with prose and static figures; add interaction only where it genuinely helps the reader.

Notes

  • This skill is the single shine entry point in every harness; Claude Code surfaces it as /moonshine:shine.
  • For the structured Vite + React + Velite project flavor (multi-file content, markdown directives, React figures, in-place editing, authorship feedback), use $still instead. When the user hasn't picked a substrate, SKILL.md § "Two Substrates" makes still the default.

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.
