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 | $0.02551 | $0.02551 |
| Opus 5.5 | $0.01020 | $0.01020 |
| Sonnet 5.5 | $0.00510 | $0.00510 |
| Haiku 4.5 | $0.00255 | $0.00255 |
Grade A, and why
openprocmon 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 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.

OpenProcMon - CLAUDE.md
Project Overview
OpenProcMon is an open-source Process Monitor implementation for real-time monitoring of process, file and registry activity on Windows. Layered architecture: a kernel miniFilter driver captures events -> the SDK layer talks to the driver over a Filter Manager port -> the GUI layer presents the event data.
The SDK and GUI are a completed ground-up Rust rewrite of the original C++ implementation, which is kept under cpp-backup/ for reference. The kernel driver is unchanged.

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.

openprocmon CLAUDE.md is an instructions file published in the GitHub repository progmboy/openprocmon (364 stars, last pushed 13d ago), licensed MIT. It adds 2,551 tokens to every session, about $0.0102 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 2026-08-30.
