20 specialized agents and 9 commands for exploring, analyzing, and improving existing Python codebases. Includes analysis scripts for correctness and concurrency scanning against a bug-shape catalog, tiered lint triage, mypy integrity checks, import graphing, complexity measurement, test correlation, type coverage, dead symbol detection, tech debt collection, git history analysis, web-framework wiring and ORM-schema checks, a Phase 3 publication pipeline, and threat-model discovery with a security-claims gate.

ReviewToolkits/code-review-toolkit 6

Rules your coding agent physically cannot ignore. A Claude Code plugin (and an LLM-agnostic rule pack) that intercepts the agent's own tool calls instead of asking it nicely: PreToolUse denies an edit that skips read-before-edit, plants an unjustified suppression marker, hardcodes a secret or a machine-specific path, or piles rolling patches onto one file; a Bash gate refuses --no-verify, force-push and similar bypasses; and a nine-layer Stop gate refuses to let a completion claim end the turn without evidence, a convergence self-quiz, a fidelity check against the original request and a one-line TL;DR. Twelve rules (ten hook-backed), per-project Imperial Edict regexes you define yourself, a repo-wide sync gate, and CI drift gates that derive every documented number from the code. Standard library only; every guard fails open, so a bug in the discipline can never brick your agent. Release history: CHANGELOG.md.
