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 5.1 | $0.00313 | $0.00313 |
| Opus 5 | $0.00156 | $0.00156 |
| Sonnet 5 | $0.00063 | $0.00063 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade C, and why
ccusage-web 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 7d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Common Issues
npm ci fails with "package.json and package-lock.json are in sync" error
Symptoms:
npm ci can only install packages when your package.json and package-lock.json or npm-shrinkwrap.json are in sync.
Missing: @swc/[email protected] from lock file
Cause: This happens when dependencies are added/updated but package-lock.json wasn't properly regenerated, or when transitive dependencies change.
Fix:
rm -rf node_modules package-lock.json && npm install
Then commit and push the regenerated package-lock.json.
Prevention: After any dependency changes, always run npm install and commit both package.json and package-lock.json together.
Project Structure
- Frontend: Next.js 15 with App Router, TypeScript, Tailwind CSS
- Backend: Next.js API routes with SQLite (better-sqlite3)
- Charts: ECharts for React
- Agent: Python 3 (preferred) or Node.js for usage data collection
Deployment
- Docker-based deployment
- Uses
npm cifor reproducible builds (requires synced lock file) - Alpine Linux base image
Agent
The agent (/agent) supports both Python 3 and Node.js:
- Python 3.6+ (recommended, uses only standard library)
- Node.js 18+ (fallback)
Setup script auto-detects available runtime.
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.
