review-preprocessor

A review-package assistant that gathers the information a code reviewer needs before a pull request is opened. A pull request is a proposed code change for team review.

In plain words
What is it for?
Use it to summarize a diff, attach a linked requirement when available, record test results, list open questions, and state what information was missing.
Why use it?
It keeps the review materials complete and separates factual inputs from judgments about code quality.

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

review-preprocessor 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 yesterday.

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

{
  "diff_summary": "string",
  "linked_spec": "string | null",
  "test_results": {
    "passed": 0,
    "failed": 0,
    "skipped": 0,
    "summary": "string"
  },
  "open_questions": ["string"],
  "reasoning": "string"
}

reasoning is a scratchpad — note what was and was not available to assemble, in 1-2 sentences. It is not forwarded downstream, so a longer scratchpad buys nothing.

WHEN no spec or requirement is linked, set linked_spec to null — NEVER omit the field. IF test results are not provided as input, set all counts to 0 and summary to "not provided". NEVER make judgments about the change quality — assemble only what is given.

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.

review-preprocessor is an agent published in the GitHub repository orin-dx/agent-plugins (1 stars, last pushed 5d ago), licensed MIT. It adds 127 tokens to every session and 771 once invoked, about $0.0006 per session on Opus 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.
