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 | $0.00163 | $0.00163 |
| Opus 5.5 | $0.00065 | $0.00065 |
| Sonnet 5.5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
ccmux AGENTS.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 2mo 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.
What it actually says
Project instructions
Read CLAUDE.md in this repository root before making any change. It is the single source of
truth for working here — repository conventions, what must never be published, the order in which
work is finished, committed and released, and the runtime rules (Bun, never Node/npm).
This file exists only so that agents looking for AGENTS.md are pointed at that one file. It
deliberately carries no rules of its own. A second copy drifts: the one that used to live here had
fallen six weeks behind and still taught the runtime conventions while silently missing the rule
that this repository is public and must never contain private hostnames, machine labels or
session names — exactly the rule whose absence is most expensive.
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.

ccmux AGENTS.md is an instructions file published in the GitHub repository max-listov/ccmux (2 stars, last pushed 6d ago), licensed MIT. It adds 163 tokens to every session, about $0.0007 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.
