Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.07138 | $0.07138 |
| Opus 5 | $0.03569 | $0.03569 |
| Sonnet 5 | $0.01428 | $0.01428 |
| Haiku 4.5 | $0.00714 | $0.00714 |
Grade C, and why
visual-stack CLAUDE.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 2d 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.

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

The opening of the file, as written. The whole thing — 553 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this is
Visual Stack — a coding-agent plugin for interactive wireframing and UI review.
The user comments directly on a wireframe (or a running app) in a browser
workspace; the agent applies the feedback and publishes the next version into
the same workspace. The repo is a Claude Code plugin marketplace
(.claude-plugin/marketplace.json) with one plugin, plugins/vstack/, which
also ships a Codex manifest (.codex-plugin/) and a Grok host adapter
(skills/review/hosts/grok.md).
This repo is the thing people install; nothing is installed into it. No
.grok/skills/, no .claude/skills/, no vendored copy of our own plugin — a
host that discovers skills from a project directory gets instructions in its
host adapter, not a checked-in skill directory that then has to be kept in sync.
.claude/commands/ is the one exception, and it holds maintainer tooling only:
commands for working on this repo, which ship to nobody and mirror no part of
the plugin. /ship is the only one. A command there states no rule of its own —
it points at the section of this file that owns the rule.
Plain Node ≥ 18 ES modules, standard library only. There is no package.json,
build step, bundler, or linter. (node_modules/ at the root appears only when
recording the README demo, which installs playwright-core.)
Commands
Tests are standalone Node scripts — run them directly, one file per suite:
node plugins/vstack/skills/review/tests/review-lifecycle.mjs # end-to-end review server round-trip
node plugins/vstack/skills/review/tests/host-profiles.mjs # host profiles conform to host.schema.json
node plugins/vstack/skills/review/tests/workdir.mjs # .vstack/local working-dir resolution
node plugins/vstack/skills/review/tests/round-gate.mjs # `unanswered` and the Stop hook that runs it
node plugins/vstack/skills/review/tests/update-check.mjs # per-host update detection and the banner it produces
node plugins/vstack/skills/review/tests/design-tokens.mjs # the shell's palette still matches design/tokens.css
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.

visual-stack CLAUDE.md is an instructions file published in the GitHub repository Cavalry-Collective/visual-stack (11 stars, last pushed 13d ago), licensed MIT. It adds 7,138 tokens to every session, about $0.0357 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
