.claude/agents/pr-reviewer.md

pr-reviewer is an agent for Claude Code from branover/hexgraph. It costs 91 tokens per session (1,011 once invoked), scanned A, original, AGPL-3.0.

An independent reviewer for pull requests, which are proposed code changes waiting to be merged.

In plain words
What is it for?
It is for reviewing branch differences, checking loopback and sandbox restrictions, ensuring secrets are not logged, confirming execution and network access are opt-in, and checking tests, documentation, and migration details.
Why use it?
It checks whether the changes work correctly and whether they preserve security rules, test quality, and required documentation before merging.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is branover/hexgraph's own configuration. It tells Claude Code how to work on hexgraph itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything hexgraph configures →

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

pr-reviewer 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.

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.
