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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.01637 | $0.01637 |
| Opus 5 | $0.00818 | $0.00818 |
| Sonnet 5 | $0.00327 | $0.00327 |
| Haiku 4.5 | $0.00164 | $0.00164 |
Grade A, and why
explore-claude-code CLAUDE.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 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.
How it starts
The opening of the file, as written. The whole thing — 64 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
An interactive educational website that teaches Claude Code features by simulating a project you explore. Static HTML/CSS/JS — zero build steps, no framework, no bundler.
Serving Locally
# Any static server, pointed at the site/ directory
npx serve site
python -m http.server -d site 8080
Opening site/index.html directly also works (fetches manifest via relative path).
Architecture
All educational content is stored as JSON strings inside site/data/manifest.json. This single file drives the entire UI — tree structure, file content, labels, badges, and feature groupings. To add or change content, edit the manifest.
Component classes (all vanilla JS, no modules, loaded via <script> tags):
App(app.js) — Controller. Loads manifest, wires components, handles keyboard nav (arrow keys), hash routing, traffic light buttons, the Cmd/Ctrl+K search palette, the light/dark theme toggle, and the void easter egg (minimize button → canvas particle animation).FileExplorer(file-explorer.js) — Sidebar tree. Draws connector lines (├── └──) on<canvas>elements inside.tree-children-guidedcontainers..claudeandbuilt-inare auto-expanded on load (expandedDirs).ContentLoader(content-loader.js) — Renders file content. Has a hand-rolled markdown parser supporting: YAML frontmatter (rendered as tables), fenced code blocks, tables, lists, inline formatting, and links. Markdown files get a Rendered/Raw toggle. Syntax highlighting via Prism.js. Each page header carries a "Copy link" button that copies a deep link (origin + #path).Terminal(terminal.js) — Right-side panel. Interactive slash command emulator (/help,/init,/doctor,/diff,/compact,/model,/cost,/status,/config,/memory). Animated output sequences.Search(search.js) — Cmd/Ctrl+K command palette. Fuzzy-matches over a flattened index of every file's title, path, description, and badge (metadata only, not full body text), then jumps to the result viaexplorer.selectPath. Opens from the title-bar search button or the shortcut.ProgressTracker(progress.js) — Tracks visited features in localStorage under keytcc-progress.
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.

explore-claude-code CLAUDE.md is an instructions file published in the GitHub repository LukeRenton/explore-claude-code (308 stars, last pushed 22d ago), licensed MIT. It adds 1,637 tokens to every session, about $0.0082 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
