util.gh-pr-review

util.gh-pr-review is a command for GitHub Copilot from stefaniuk/loadout. It costs 8 tokens per session (5,440 once invoked), scanned A, original, MIT.

A pull request review command that compares a branch's changes with its actual base branch and uses relevant architecture and coding guidance. A pull request is a proposed change for teammates to review before it is merged.

In plain words
What is it for?
Use it to produce a focused, evidence-based review of a pull request, including findings about behaviour, design context, and affected code.
Why use it?
It helps reviewers check whether the implementation matches the stated intent and identify issues using the parts of the system affected by the change.

Command for GitHub Copilot

Written for GitHub Copilot: a Copilot chat mode or prompt.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash .github/prompts/util.gh-pr-review.sh.

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

util.gh-pr-review 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 yesterday.

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 — 359 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mandatory preparation:

  • Read the constitution and honour its non-negotiable rules.
  • Read the Pull Request template at pull_request_template.md only to understand the author's reporting structure; the review output uses its own structure defined below.
  • Read the technology-specific instructions only for languages actually touched on this branch (look at the stat in the bounded report; do not preload every instruction file). For example python.instructions.md, shell.instructions.md, makefile.instructions.md.
  • Load design context (.copilot/analysis/repository-map.md, component-*.md, runtime-flow-*.md, domain-*.md, c4-*.dsl, *-infrastructure.*) only if those files actually exist and only when the diff materially touches the components they describe. Do not block the review on missing design context.

Goal 🎯

Act as a senior peer reviewer for the pull request that merges this branch into its detected base branch (see the Scope policy). Produce a focused, constructive, evidence-based review whose primary job is to:

  1. Verify intent vs implementation - does the code do what the PR title/description and commit messages claim, no more and no less?
  2. Surface merge-blockers first - correctness, safety, security, contract, and data-integrity issues.
  3. Coach, don't nitpick - every finding is actionable, prioritised, and evidence-backed; lower-severity items are suggestions, not demands.

The reviewer's deliverable is a Markdown report saved under .copilot/analysis/gh-pr-review-YYYYMMDD-<slug>.report.md (where <slug> is pr-<number> when a PR is known, otherwise the sanitised branch name; this prevents collisions when several PRs are reviewed on the same day) and an overall verdict (Approve / Request changes / Comment).

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.
