A pull request review tool examines proposed code changes before they are merged into a shared codebase. It checks code quality, security, tests, project rules, and consistency with AI-tool instructions.

Use it to review a git diff or changed files, report findings by severity, add file-specific comments, and recommend approval or changes.

It helps find problems and rule violations before they reach the main codebase, when they are easier to fix.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.00910
Opus 5.5	$0.00018	$0.00364
Sonnet 5.5	$0.00009	$0.00182
Haiku 4.5	$0.00004	$0.00091

Security

Grade A, and why

pr-reviewer 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 2mo 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.

Skill: Pull Request Reviewer

Purpose

Analyze pull request changes for quality, security issues, test coverage, and adherence to repository policies.

Inputs

diffFile: Path to git diff or list of changed files.
projectRoot: Root directory of the target project.

Outputs

Review summary with findings categorized by severity.
Inline comments for specific issues.
Approval or change request recommendation.

Procedure

Step 1: Parse Diff

Extract list of modified, added, and deleted files.
Identify file types (source code, tests, config, documentation).
Calculate scope of changes (lines added/removed).

Step 2: Run Scope Guard

Execute: node tools/scope-guard.mjs <projectRoot> <changedFiles>

Ensure all changes are within the allowed scope.

Flag any violations.

Step 3: Detect Project Type

Execute: node tools/project-detect.mjs <projectRoot>

Determine applicable policies and skills.

Step 4: Load Relevant Policies

Based on project type, read:

../../../AGENTS.md (always — workspace scope and routing rules)
../../../policies/frontend-policy.md (if frontend)
../../../policies/backend-policy.md (if backend)

Step 5: Code Quality Check

For each changed source file:

Style Consistency
- Verify adherence to project conventions.
- Check for unrelated formatting changes (flag as noise).
Type Safety (TypeScript/Java/Python with types)
- Identify any types or missing type annotations.
- Flag type assertions without justification.
Error Handling
- Check for unhandled promise rejections.
- Verify appropriate error responses in API endpoints.
Security
- Detect hardcoded secrets or credentials.
- Identify SQL injection risks (string concatenation in queries).
- Flag unvalidated user input.
Performance
- Identify inefficient loops or algorithms.
- Flag synchronous operations in async contexts.

Step 6: Accessibility Check (Frontend Only)

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.
