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 | $0.00089 | $0.01290 |
| Opus 5.5 | $0.00036 | $0.00516 |
| Sonnet 5.5 | $0.00018 | $0.00258 |
| Haiku 4.5 | $0.00009 | $0.00129 |
Grade A, and why
macwright-dev 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 1mo 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.

Build & Test Workflow
npm run build # TypeScript → dist/
CRITICAL: After npm run build, the MCP server process must be restarted to pick up new tools. The server runs from dist/index.js — changes only take effect after restart + rebuild. The Claude Code IDE integration will restart on reconnect.
To verify a new tool works: use run_applescript to test the underlying AppleScript first (no restart needed), then rebuild and use the actual MCP tool after restart.
Adding a New Tool
- Find the appropriate
src/tools/*.tsfile (or create one) - Add
server.registerTool(name, schema, handler)call - Export the registration function from the file
- Import and call it in
src/index.tsif new file npm run build- Test via AppleScript equivalent first to validate logic
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.

macwright-dev is a skill published in the GitHub repository ruchit-p/macwright (0 stars, last pushed 2mo ago), licensed MIT. It adds 89 tokens to every session and 1,290 once invoked, about $0.0004 per session on Opus 5.5. 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.
