rigor-plugin-review

rigor-plugin-review is a skill for Claude Code, Codex from rigortype/rigor. It costs 55 tokens per session (1,907 once invoked), scanned A, original, MPL-2.0.

A review workflow for an existing Rigor plugin, which adds project-specific knowledge to Rigor's code analysis. It compares the plugin with the current plugin-writing rules and produces a prioritized upgrade path.

In plain words
What is it for?
It is for assessing and planning changes to a bundled or custom Rigor plugin, not for creating a new one.
Why use it?
It reveals outdated hooks, configuration patterns, documentation, or hand-written code that should be modernized.

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

rigor-plugin-review scanned grade A with 1 finding 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Rigor Plugin Review

Audit an existing Rigor plugin — a bundled one in the rigor monorepo (plugins/ or examples/), or your own rigor-<id> gem — against the current Rigor::Plugin::Base authoring contract, and hand back a prioritized upgrade path. This is the review / upgrade counterpart to rigor-plugin-author (which creates new plugins).

Plugins written before a contract addition keep working — the gate is compatibility, not currency — but they drift from the idiom other authors copy. The commonest drift, in rough order of how often it appears:

  1. Config defaults declared with a DEFAULT_* constant + config.fetch(k, DEFAULT) instead of config_schema {kind:, default:} (ADR-40).
  2. Hand-rolled boilerplate the ADR-60 WD4 authoring helpers now own — a Levenshtein "did you mean", a @table/@load_error memo + rescue, a Diagnostic.new where a node exists.
  3. A hand-rolled AST walk where the engine-owned node_rule now fits (ADR-37 / ADR-52).
  4. Removed / renamed hooks still named — flow_contribution_for (deleted, ADR-52 WD3) or type_specifier (removed in 0.3.0; renamed to narrowing_facts, ADR-80).
  5. Stale docs — archaeology about deleted hooks, pinned version references that no longer mean anything.

First: load the version-current copy

This skill audits against a contract that moves release to release (hook renames, new helpers, deprecations), so its checklist — in its references/ files — is only as good as the Rigor it ships with. Follow the copy that ships with the installed Rigor rather than any vendored or frozen copy of this file. Get the complete current procedure (body + all references, inline) in one call:

rigor skill --full rigor-plugin-review

If you already loaded this skill via rigor skill you have the current copy — just proceed. If rigor is not on PATH, this task needs it: run rigor-next-steps to install Rigor first, then come back.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
