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 | $0.00800 | $0.00800 |
| Opus 5 | $0.00400 | $0.00400 |
| Sonnet 5 | $0.00160 | $0.00160 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
specter-mcp 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 9d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md - Project Instructions for Claude
Communication Style
ALWAYS use the AskUserQuestion tool when presenting questions or options to the user. Do not ask questions inline in text responses. The AskUserQuestion tool provides a better UX with structured options.
Project Context
Specter MCP is a KMM (Kotlin Multiplatform Mobile) Diagnostic & Execution Engine that acts as "hands and eyes" for AI agents working with mobile projects.
Tech Stack
- TypeScript 5.x (Node.js 20+)
- @modelcontextprotocol/sdk
- sharp (image processing)
- xml2js (UI hierarchy parsing)
Architecture
- Primary Agent + Specialized Worker model
- Primary agent (Claude Sonnet) handles high-level reasoning
- Worker models handle specific tasks:
- Log analysis → Claude Haiku
- Vision/UI analysis → Vision-capable model
- Code reasoning → Primary model
Tool Domains
- Environment & Build: Device management, cache cleaning, builds
- Testing & QA: Unit tests, Maestro E2E, linting
- UI & Observability: Screenshots, UI hierarchy, interactions, logs, deep links, app state
- iOS Crash Diagnostics: Crash log parsing, symbolication, pattern detection
- Model Routing: Task dispatching to specialized AI models
- Concurrency & Error Handling: Sequential queue, device discovery, timeouts
Design Decisions
Access & Security
- No authentication required - Claude AI or users call directly on trusted local machine
Concurrency
- Queue requests and execute sequentially to prevent resource conflicts (no parallel tool execution)
Error Handling
- When a requested device/emulator doesn't exist: Return error plus list of available devices for agent to choose
- If configured worker model (e.g., Claude Haiku) is unavailable: Fallback to primary model, accept higher cost
Timeouts
- Maximum build timeout: 30 minutes (accommodates complex projects with many dependencies)
iOS Debugging
- Crash log analysis: Parse .crash/.ips files, symbolicate with dSYM, detect crash patterns
- Xcode Instruments: Out of scope - focus on functional debugging, not performance profiling
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.

specter-mcp CLAUDE.md is an instructions file published in the GitHub repository abd3lraouf/specter-mcp (1 stars, last pushed 8mo ago), licensed MIT. It adds 800 tokens to every session, about $0.0040 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.
