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 | $0.02665 | $0.02665 |
| Opus 5 | $0.01333 | $0.01333 |
| Sonnet 5 | $0.00533 | $0.00533 |
| Haiku 4.5 | $0.00266 | $0.00266 |
Grade A, and why
capsule 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

CLAUDE.md
Project Overview
pnpm monorepo with three workspace packages:
@endorhq/capsule-web(packages/web) — SvelteKit web app that visualizes conversation logs from AI coding agents (Claude Code, Codex, Copilot, Gemini). Parses different log formats into a unified timeline and renders them in a terminal-inspired dark UI. Builds with adapter-node (default, for CLI consumption) or adapter-cloudflare (for production deploy).@endorhq/capsule-shared(packages/shared) — Shared parsers and types consumed by both the web app and the CLI.@endorhq/capsule(packages/cli) — CLI tool (capsule) with three subcommands:share(publish to GitHub Gist),export(save to local file), andserve(start a local web viewer).
The root (./) is not a workspace package — it holds monorepo tooling only (biome, lefthook).
Tech Stack
- SvelteKit 2 + Svelte 5 (runes:
$state,$derived,$props) - TypeScript (strict mode)
- Tailwind CSS v4 (new
@themesyntax,@tailwindcss/viteplugin) - Vite 7
- pnpm package manager (monorepo via
pnpm-workspace.yaml) - tsup (CLI bundling) + tsx (CLI dev)
- @clack/prompts + picocolors (CLI interactive UI)
- @sveltejs/adapter-node (default build, for
capsule serve) - @sveltejs/adapter-cloudflare (opt-in via
ADAPTER=cloudflare, for production)

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.
