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 | $0.02828 | $0.02828 |
| Opus 5 | $0.01414 | $0.01414 |
| Sonnet 5 | $0.00566 | $0.00566 |
| Haiku 4.5 | $0.00283 | $0.00283 |
Grade A, and why
pocket-server 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.
How it starts

Project Overview
Pocket Server is a Node.js + Hono WebSocket server that provides AI agent capabilities, file system operations, terminal management, and background agent orchestration. Built with TypeScript and ESM modules, it serves as the backend for the Pocket Agent mobile app.
Architecture
Core Design Principles
- Event-driven mailbox pattern - Each session has its own AgentRunner with strict ordering
- Server-authoritative storage - All conversation data persisted to
data/sessions/ - Streaming-first - Optimized for real-time WebSocket streaming with frame aggregation
- Module isolation - Clean separation between agent, auth, file system, and terminal modules

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.

pocket-server CLAUDE.md is an instructions file published in the GitHub repository yayasoumah/pocket-server (838 stars, last pushed 10mo ago), licensed Apache-2.0. It adds 2,828 tokens to every session, about $0.0141 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 2026-08-30.
