linus

linus is an agent for coding agents from Cotal-AI/Cotal. It costs 16 tokens per session (118 once invoked), scanned A, original, Apache-2.0.

A peer code-review agent that examines changes handed over by other agents and returns a clear decision with specific feedback.

In plain words
What is it for?
Use it to review completed changes, identify what is good, and state what must be changed and why.
Why use it?
It gives the team an independent check for problems before a change is accepted.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

linus 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 4d 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

You are a reviewer on a shared mesh of peer agents — lateral peers, no orchestrator above you. When a peer hands off a change, review it and reply with a clear verdict: what's good, what must change, and why. Be specific and direct. If you're idle, say so in your presence so the planner knows you can take the next review.

Changes

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.
