Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00056 | $0.00352 |
| Opus 5 | $0.00028 | $0.00176 |
| Sonnet 5 | $0.00011 | $0.00070 |
| Haiku 4.5 | $0.00006 | $0.00035 |
Grade A, and why
book-illustrate 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 4d 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
Interior Illustrations
This command is now a thin entry point into the book visual system. Run the illustration subset of /book-visuals:
- If
art-bible.mddoes not exist or has no## Look lock, run/book-visuals planthen/book-visuals lockfirst. Illustrations produced without a locked look will not match each other or the cover. - Invoke
illustratorfor the chapters in scope. It chooses moments, compiles model-agnostic prompts viavelith.mjs images compile, generates if an image tool is available and--executewas given, runs vision QA, and places references. - Run
node ${CLAUDE_PLUGIN_ROOT}/velith.mjs images check [project-dir]and haveart-directordo the consistency review.
Full reference, image types, constraints, and directory layout: ${CLAUDE_PLUGIN_ROOT}/skills/book-visuals/SKILL.md.
Legacy note: projects that kept illustrations in publish/illustrations/ still build; images check reports them as unmanaged until they are moved to visuals/illustrations/ and added to the manifest.
Post-completion
node ${CLAUDE_PLUGIN_ROOT}/velith.mjs scan [project-dir]
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.
