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 | $0.00883 | $0.00883 |
| Opus 5 | $0.00441 | $0.00441 |
| Sonnet 5 | $0.00177 | $0.00177 |
| Haiku 4.5 | $0.00088 | $0.00088 |
Grade A, and why
claude-lens 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 10d 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 — 86 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.
Development Commands
npm run dev # Run CLI in development mode (tsx)
npm run build # Compile TypeScript to dist/
npm run typecheck # Type check without emitting
Run specific commands in dev:
npm run dev # Launch TUI (default)
npm run dev -- scan # Text summary
npm run dev -- scan --json # Full scan as JSON
npm run dev -- disable agent foo # Disable an agent
Architecture
Entry flow: bin/claude-lens.ts → src/cli/index.ts → routes to command or TUI

├── cli/commands/ # CLI command handlers (scan, plugins, enable, disable, etc.)

Data flow:
- Scanner reads Claude Code files (
~/.claude/, project.claude/,.mcp.json) - Returns typed data structures (Plugin[], Agent[], McpServer[], etc.)
- CLI formats and outputs; TUI renders with React/Ink
- Actions modify files/settings; scanner re-runs to refresh state

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.

claude-lens CLAUDE.md is an instructions file published in the GitHub repository radumardale/claude-lens (4 stars, last pushed 7mo ago), licensed MIT. It adds 883 tokens to every session, about $0.0044 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 2026-08-31.
