review-pr

review-pr is a skill for Claude Code from NVIDIA-NeMo/Megatron-Bridge. It costs 64 tokens per session (2,439 once invoked), scanned A, original, Apache-2.0.

A structured process for reviewing pull requests, commits, or local code changes. It focuses on concrete problems in the code and does not change files unless fixes are requested.

In plain words
What is it for?
Use it to review correctness, APIs, tests, examples, documentation, performance, and project-specific conventions, then prepare specific review comments.
Why use it?
It makes reviews more consistent by reading the change first, checking relevant project rules, and limiting tests to targeted checks instead of running the entire test suite.

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-pr 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 9d 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.

Review PR

Use this skill to review a change in staged passes. Do not use subagents or tmux unless the user explicitly asks for them.

Ground Rules

  • Pull the artifact first: read the PR, commit, diff, log, or files under review before forming conclusions.
  • After the artifact is read, load only the relevant repo skills for the touched areas, such as linting-and-formatting, testing, adding-model-support, build-and-dependency, cicd, or a performance skill.
  • Preserve user changes. Do not edit files during a review unless the user asks for fixes.
  • Do not modify 3rdparty/Megatron-LM/. If the reviewed change touches it, flag that boundary.
  • Do not run the full test suite. Run only targeted checks, using uv run python -m pytest or the repo-approved command form.
  • Prefer findings with concrete file and line evidence. Drop low-confidence or purely stylistic comments unless the user asks for a strict style pass.

Repository Review Principles

Apply these principles to implementation, APIs, recipes, tests, examples, and documentation. They are acceptance criteria, not optional polish.

  1. Correctness is the gate. Preserve numerical semantics, distributed invariants, checkpoint compatibility, API contracts, and failure behavior. Prefer an explicit error over a silent fallback that can produce incorrect training, conversion, or inference results. Performance or simplicity never justifies behavior that is wrong or cannot be validated.
  2. Performance is a product requirement. Once correctness is established, protect throughput, latency, memory efficiency, and distributed scaling, especially in training hot paths. Do not accept an avoidable regression for cleaner-looking code or a more convenient abstraction without measurements and an explicit tradeoff. Treat extra synchronization, communication, materialization, copies, allocations, and host overhead as review concerns.
  3. Design for both users and developers. User-facing behavior should have safe defaults, coherent configuration, actionable errors, and discoverable examples. Developer-facing code should have explicit contracts, clear names and ownership, local reasoning, focused tests, and minimal special cases. Readability includes the public workflow as well as the implementation.
  4. Keep optimized complexity behind clear boundaries. A fast implementation may be internally specialized, but it should not leak accidental complexity into public APIs or every call site. Isolate the optimized path, document its invariants, and test both its behavior and fallback or error path.

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-pr is a skill published in the GitHub repository NVIDIA-NeMo/Megatron-Bridge (904 stars, last pushed today), licensed Apache-2.0. It adds 64 tokens to every session and 2,439 once invoked, about $0.0003 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.
