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 | $0.02199 | $0.02199 |
| Opus 5 | $0.01099 | $0.01099 |
| Sonnet 5 | $0.00440 | $0.00440 |
| Haiku 4.5 | $0.00220 | $0.00220 |
Grade A, and why
psamvault-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.
How it starts
The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
psamvault-mcp — AI Agent Instructions
You have access to the psamvault MCP server which provides tools for managing credentials securely. These tools let you use stored credentials without ever seeing their plaintext values.
Installing / repairing the MCP connection
If tools are missing or the host cannot start the server, follow docs/troubleshooting/MCP-INSTALL-AND-CONNECT.md.
Summary: install with pipx, configure the host with the absolute pipx
path, set PYTHONPATH="", reload the session, ensure psamvault login,
smoke-test with psamvault-mcp --version or psamvault-mcp --help
(never leave a bare stdio process running as a “test”). Also see
docs/troubleshooting/PYTHONPATH-CONFLICT.md.

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.
