A setup guide for defining the rules that a repository's automated code reviewer should follow.

In plain words
What is it for?
It is for discovering current repository guidance and preparing approved review settings and rule files for specclaw-review.
Why use it?
It prevents review gates from being added silently and helps preserve existing project governance instead of copying rules that may become outdated.

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

rules 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

specclaw-review: create the review rules for this repo

Two outputs:

  1. a review: block in .specclaw/config.yaml;
  2. rule files in .specclaw/review/rules/.

Write nothing until the user approves what you show them. Rules decide what blocks a PR, so a rule written silently is a gate nobody agreed to.

1. Find what the repo already has

Run specclaw-review discover (or call the review_discover MCP tool). It is read-only and lists:

  • the repo's governance by category, with sizes;
  • whether those files define severity;
  • the existing repo rules;
  • how much review history is on disk;
  • whether a PR host can be read;
  • a suggested review: block.

Before you go on:

  • Existing governance wins. Point review.governance at those files; they are read fresh every round. Never copy them into rule files, because copies go stale.
  • Decisions/ADRs stay out of the rulebook. List them for the user. The reviewer reads them with its tools when a change touches them.
  • Over budget: if the inlined size is over budget, propose which files to drop from governance, smallest value first: long guides, tutorials, and anything an ADR already covers. Show the size before and after.
  • Severity: if the files define severity, say so. severity: project applies by default, so the repo's own idea of "major" wins.

2. Draft rules only for what is missing

Mine the repo's own review history and write down what it keeps getting wrong. Never write generic advice; the plugin's packs already hold that.

Sources, best first:

  1. Past PR review comments. Read only, last 30–50 merged PRs.
    • GitHub: gh api "repos/{owner}/{repo}/pulls/comments?per_page=100" --paginate -q '.[] | [.path, .body] | @tsv' | head -2000
    • Azure DevOps: use the token in .specclaw/.env (AZDO_TOKEN; never print it). Read _apis/git/repositories/<repo>/pullrequests?searchCriteria.status=completed&$top=50, then each PR's /threads.
  2. The repo's records: .specclaw/changes/*/learnings.md and follow-ups.md.
  3. Recurring lessons in review memory: specclaw-review learn (dry-run).

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.
