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 | $0.00747 | $0.00747 |
| Opus 5 | $0.00374 | $0.00374 |
| Sonnet 5 | $0.00149 | $0.00149 |
| Haiku 4.5 | $0.00075 | $0.00075 |
Grade A, and why
notes 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 yesterday.
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 — 82 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.
Commands
pnpm build # Compile TypeScript to dist/
pnpm dev # Watch mode for development
pnpm typecheck # Type check without emitting
pnpm lint # Run oxlint
pnpm test # Run tests
pnpm test:watch # Run tests in watch mode
make install # Build and link globally
make clean # Remove dist/ and node_modules/
Architecture
Dual-mode CLI/MCP tool for searching and managing Apple Notes:
src/
├── index.ts # Entry point - routes to CLI or MCP mode based on --mcp flag
├── cli.ts # Commander-based CLI (search, recent, folders, read, create, delete commands)
├── mcp.ts # MCP server exposing tools via @modelcontextprotocol/sdk
├── applescript.ts # AppleScript automation for create/delete operations
├── indexer.ts # Builds search indexes from Apple Notes database
├── searcher.ts # Queries indexes with fuzzy matching via MiniSearch
├── formatter.ts # Terminal output formatting with chalk
└── types.ts # Shared types and Apple date conversion utilities
Data flow:
indexer.tsreads Apple'sNoteStore.sqlitedatabase from~/Library/Group Containers/group.com.apple.notes/- Extracts text from gzipped note body data (protobuf-like format)
- Creates two indexes in
~/.notes/: FTS5 SQLite for exact search, MiniSearch JSON for fuzzy matching searcher.tsqueries MiniSearch for fuzzy results, then fetches full data from SQLite
Key dependencies:
better-sqlite3: Read Apple Notes DB and create FTS5 indexminisearch: Fuzzy search with typo tolerance@modelcontextprotocol/sdk: MCP server for Claude Code integration

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.

notes CLAUDE.md is an instructions file published in the GitHub repository cardmagic/notes (4 stars, last pushed 6d ago), licensed MIT. It adds 747 tokens to every session, about $0.0037 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.
