"""Send the code to a second and third pair of eyes, and print what they say.

A review by the person who wrote the code finds the bugs that person is capable
of imagining. This asks models that were not in the room. It reports; it never
edits — the output is prose for a human to judge, not a patch to apply.

Cheap models on purpose. This is a wide, shallow pass over a small codebase
looking for the obvious things a fresh reader notices, not a deep audit, and
paying frontier prices for it would be paying for the wrong thing.

Usage:
    OPENROUTER_API_KEY=... python3 tools/peer_review.py [--model M] [--part N]

The key is a capped child key (`orkeys create`), never a raw account key.

BRIEF = """You are reviewing CLIque: a browser-based, CLI-agnostic tmux session
manager. Python standard library only — no framework, no dependencies, no build
step. It is MIT and self-hosted by strangers, so a hole here is a hole on their
machines.

Report only. Do not write patches, do not rewrite the code, do not suggest
adding a framework or a dependency — the absence of those is the product.

Threat model, so you judge against the right bar:
- Anyone who reaches the panel gets a shell as the user who started it. That is
  stated in the README and is not a finding. What matters is whether someone
  who should NOT reach it can, or whether a read-only caller can act like a
  full one.
- It binds loopback and expects a tunnel in front of it.
- Auth is a scrypt password plus HMAC-signed session cookies, and bearer API
  tokens that are either full-access or read-only.

Deliberate, do not report as findings — but DO report a way to defeat one:
- `tmux` and `git` run from PATH. Argv is always a list; no shell is involved.
- SHA-1 in the WebSocket handshake is mandated by RFC 6455.
- The webhook may target loopback and private addresses on purpose; link-local
  is refused.
- clis.toml lets a user define arbitrary launch commands. That is the product.

Look for, in this order of value:
1. An unauthenticated or read-only caller doing more than they should: auth
   bypass, scope escape, CSRF, cross-site WebSocket hijacking, path traversal,
   SSRF, injection.
2. Crashes, hangs, deadlocks, and leaks — descriptors, threads, processes,
   unbounded memory. This runs for weeks without a restart.
3. Races. It is a ThreadingHTTPServer with background threads for the PTY
   pump, a keepalive, and a webhook watcher.
4. Logic that does not do what its own comment claims.
5. Errors swallowed in a way that leaves a state the user cannot see or fix.

For each finding: file and line, what is wrong in one or two sentences, a
concrete failing sequence, your confidence, and what you would do.

Most severe first. Say plainly when you are unsure instead of padding — a short
accurate report beats a long speculative one. If an area is clean, say so.
Judge the code, not the comments: the gap between the two is where several real
bugs have already been found."""
