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

redbook 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.

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — redbook CLI

Publishing

NEVER publish npm packages directly from local. Always use the npm-publish-cli agent to bump version and publish via CI. The GitHub Actions workflow (Publish to npm) handles publishing on push to main. Publishing locally races CI and causes workflow failures.

Dual publishing (automated):

  • npm — publishes when package.json version changes on push to main
  • ClawHub — publishes when SKILL.md changes on push to main (uses CLAWHUB_TOKEN secret)

Both are conditional jobs in .github/workflows/npm-publish.yml. Manual trigger via workflow_dispatch is also available.

Build & Test

  • npm run build — TypeScript compile + chmod
  • No test suite yet — verify manually with redbook whoami

Project Structure

  • src/cli.ts — CLI entry point, 21 commands, getClient() is the single cookie→client funnel
  • src/lib/client.ts — XHS API client (postComment, replyComment, etc.)
  • src/lib/cookies.ts — Cookie extraction with Chrome profile auto-discovery
  • src/lib/signing.ts — Request signing
  • src/lib/analyze.ts — Viral note analysis and question detection
  • src/lib/reply-strategy.ts — Batch reply filtering, templating, rate-limited execution
  • src/lib/template.ts — Viral content template extraction
  • src/lib/health.ts — Note health check: level detection, sensitive words, tag count
  • src/lib/render.ts — Card rendering (markdown → PNG via puppeteer-core, optional dep)
  • SKILL.md — Skill documentation (serves both Claude Code and OpenClaw/ClawHub)
  • .github/workflows/npm-publish.yml — CI: build, npm publish, ClawHub publish

Render Command (Optional)

  • redbook render <file> — markdown → styled PNG cards using user's existing Chrome
  • Requires puppeteer-core and marked (optional peer deps, lazy imported)
  • Uses Chrome at /Applications/Google Chrome.app/... or CHROME_PATH env var
  • No cookies/XHS API needed — purely offline
  • HTML/CSS templates embedded as TypeScript template literals (no external files)

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.
