Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.00945 |
| Opus 5 | $0.00044 | $0.00473 |
| Sonnet 5 | $0.00018 | $0.00189 |
| Haiku 4.5 | $0.00009 | $0.00094 |
Grade A, and why
pr-review-toolkit 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PR Review Toolkit
Portable PR review skill adapted for the project plugin. The upstream Anthropic
pr-review-toolkit inspired the review lenses; this implementation keeps the
procedure and rubrics in references/ so Codex, Claude Code, and Copilot can use
the same source of truth.
Review Lenses
code: project rules, bugs, contracts, maintainability, security, and performance.tests: behavioral coverage, edge cases, negative paths, and brittle tests.errors: silent failures, broad catches, hidden fallbacks, and unhelpful user-facing errors.comments: comment accuracy, stale documentation, redundant comments, and missing rationale.types: invariants, validation boundaries, encapsulation, and illegal states.simplify: clarity and refactoring opportunities while preserving behavior.all: all applicable lenses. This is the default.
Dispatch
Prefer a fresh-context reviewer when the current tool supports subagents. The
reviewer must read references/review-procedure.md and
references/review-rubrics.md before producing findings.
- Claude Code: run
Task(subagent_type: "pr-review-toolkit", ...)if the bundled agent is available; otherwise follow the fallback branch. - Codex CLI: plugin installation exposes this skill, not a Codex subagent. To use a fresh-context Codex reviewer, first copy
agents/templates/pr-review-toolkit.tomlto~/.codex/agents/or.codex/agents/, then invoke that configured agent if the current Codex surface supports/agent. If no Codex subagent is configured or available, use the fallback branch. - Copilot CLI: plugin installation exposes this skill and, through
.github/plugin/plugin.json, the.agent.mdreviewer inagents/templates/. Invoke that configured agent when the current Copilot surface supports custom agents. If running outside a plugin install, copyagents/templates/pr-review-toolkit.agent.mdto.github/agents/or~/.copilot/agents/. If no custom agent is available, use the fallback branch. - Fallback: run the review inline in the current context after reading both reference files. This is the portable default path.
What ships with it
3 files 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.
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.

pr-review-toolkit is a skill published in the GitHub repository neuromechanist/research-skills (45 stars, last pushed 10d ago), licensed BSD-3-Clause. It adds 89 tokens to every session and 945 once invoked, about $0.0004 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 2026-08-30.
