capsule: Instructions file for Claude Code

CLAUDE.md

capsule CLAUDE.md is an instructions file for Claude Code from endorhq/capsule. It costs 2,665 tokens per session, scanned A, original, Apache-2.0.

Project instructions for Capsule, a pnpm monorepo containing a SvelteKit web app, shared parsers, and a command-line tool. A monorepo keeps multiple related packages in one repository; Capsule displays AI coding-agent conversation logs and can share, export, or serve them.

In plain words
What is it for?
Use them when building, running, or changing Capsule’s SvelteKit interface, log parsers, shared types, CLI commands, or deployment setup.
Why use it?
They explain the package layout, technologies, and commands needed to develop the web app, shared code, and CLI without searching through the repository first.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is endorhq/capsule's own configuration. It tells Claude Code how to work on capsule itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything capsule configures →

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

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 2mo 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.

CLAUDE.md

Project Overview

pnpm monorepo with three workspace packages:

  1. @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).
  2. @endorhq/capsule-shared (packages/shared) — Shared parsers and types consumed by both the web app and the CLI.
  3. @endorhq/capsule (packages/cli) — CLI tool (capsule) with three subcommands: share (publish to GitHub Gist), export (save to local file), and serve (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 @theme syntax, @tailwindcss/vite plugin)
  • 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)

Commands

Web App (packages/web)

  • pnpm dev — Start dev server (proxied from root)
  • pnpm build — Build with adapter-node + PUBLIC_DISTRIBUTION=local (proxied from root)
  • pnpm -C packages/web build:cloudflare — Build with adapter-cloudflare for production
  • pnpm -C packages/web check — Type-check (svelte-kit sync + svelte-check)
  • pnpm -C packages/web preview — Preview production build

CLI (packages/cli)

  • capsule share [file] — Publish a session to GitHub Gist
  • capsule export [file] — Save an anonymized session to a local file
  • capsule serve [--port N] — Start a local web viewer (default port 3123)
  • capsule --help — Print usage
  • pnpm -C packages/cli dev — Run CLI via tsx (use npx tsx src/index.ts <command> for subcommands)
  • pnpm -C packages/cli build — Bundle CLI to dist/index.js

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.
