Use when reviewing pull requests, examining code changes, or providing feedback on code quality. Covers security, performance, testing, and design review.” [Functional Software, Inc. dba Sentry · upstream description ↗](https://github.com/getsentry/skills/blob/d18b7aa8ba878354e5c348310230e652f7690f9c/skills/code-review/SKILL.md) Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - The checklist separates defects that should block a change from style comments that should not. - Schema, API, new-dependency, performance-critical, and security-sensitive changes are flagged for a senior reviewer rather than treated as an ordinary approval. ### A good fit for - A first-pass review of a Sentry change that should stay polite and specific. - Deciding that a remaining nit is not a reason to withhold approval. - Review a change for concrete runtime, security and compatibility risks without blocking on personal style. - Identify schema, API-contract, dependency-adoption, and performance-path changes that need senior review. ### Weigh up before choosing - The file is a checklist. It has no gh command, so it does not submit a GitHub review or change the code. - The develop.sentry.dev link is a reference, not a fetch the file performs. - This review did not execute the resource. - A review checklist does not establish test execution or absence of defects; performance patterns need an actual exercised path and representative workload. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - skills/code-review/SKILL.md - LICENSE - README.md - vercel-labs/skills@48dc9e8eb8aa19040e91cb90ba0b642c9cbad57e:README.md ### Our findings - It asks for runtime, performance, compatibility, and security problems, and it says not to block a pull request for style. - It does not call GitHub. The handbook URL is only a link, so this file does not retrieve the live guideline page. - It does not edit the diff, and it does not treat missing tests as something the checklist itself can add. - The guideline distinguishes design, test coverage and long-term risk and treats minor stylistic preferences as nonblocking. - The long-term-impact checklist explicitly routes database schema changes, API contract changes, new framework or library adoption, performance-critical paths, and sensitive functionality to senior review. ### Not established by this review - The resource was not executed and its tools were not called. - No pull request was reviewed with this checklist. - Not executed: it was not installed or run. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Add a skill to your workflow. [Upstream setup instructions ↗](https://github.com/vercel-labs/skills/blob/48dc9e8eb8aa19040e91cb90ba0b642c9cbad57e/README.md) DOCUMENTED COMMAND npx skills add getsentry/skills/skills/code-review Copy command ↗ Run in your terminal to choose your AI tools, project or global scope, and installation method. This short command follows the current upstream version; the review covers the revision shown above. Optional: install the reviewed revision Keeps the original source and installer version where recorded, while leaving your AI tools and installation scope for you to choose. npx skills add https://github.com/getsentry/skills/tree/d18b7aa8ba878354e5c348310230e652f7690f9c/skills/code-review Copy reviewed-revision command ↗ - The command pins only this skill at the reviewed commit. The installer was not executed. - Do not install the whole repository. That would install skills this review did not select. - For manual installation instead, download the complete bundle from https://undominated.ai/resources/skills/getsentry-code-review/bundle.zip and extract it into a new directory. It holds SKILL.md unchanged at revision d18b7aa8, the upstream licence and an attribution file. - Place the extracted directory in your host's documented skills directory, named code-review. Keep SKILL.md and the licence together. ### Before you start - Node.js and npm - Permission to change the checkout the skill names ### Compatibility Agent Skills hosts · A git or GitHub checkout you are allowed to change ### Implementation Markdown ### Prompt text. It does not by itself post a review. - Read the change under review - Write review comments only if the host is separately allowed to - Reads code and tests; publishing reviews or approving a PR is a separate repository action. ### Cost model Apache-2.0 instructions at no charge.

Use when reviewing pull requests, examining code changes, or providing feedback on code quality. Covers security, performance, testing, and design review. --- # Sentry Code Review Follow these guidelines when reviewing code for Sentry projects. ## Review Checklist ### Identifying Problems Look for these issues in code changes: - **Runtime errors**: Potential exceptions, null pointer issues, out-of-bounds access - **Performance**: Unbounded O(n²) operations, N+1 queries, unnecessary allocations - **Side effects**: Unintended behavioral changes affecting other components - **Backwards compatibility**: Breaking API changes without migration path - **ORM queries**: Complex Django ORM with unexpected query performance - **Security vulnerabilities**: Injection, XSS, access control gaps, secrets exposure ### Design Assessment - Do component interactions make logical sense? - Does the change align with existing project architecture? - Are there conflicts with current requirements or goals? ### Test Coverage Every PR should have appropriate test coverage: - Functional tests for business logic - Integration tests for component interactions - End-to-end tests for critical user paths Verify tests cover actual requirements and edge cases. Avoid excessive branching or looping in test code. ### Long-Term Impact Flag for senior engineer review when changes involve: - Database schema modifications - API contract changes - New framework or library adoption - Performance-critical code paths - Security-sensitive functionality ## Feedback Guidelines ### Tone - Be polite and empathetic - Provide actionable suggestions, not vague criticism - Phrase as questions when uncertain: "Have you considered...?" ### Approval - Approve when only minor issues remain - Don't block PRs for stylistic preferences - Remember: the goal is risk reduction, not perfect code ## Common Patterns to Flag ### Python/Django ```python # Bad: N+1 query for user in users: print(user.profile.name) # Separate query per user # Good: Prefetch related users = User.objects.prefetch_related('profile') ``` ### TypeScript/React ```typescript // Bad: Missing dependency in useEffect useEffect(() => { fetchData(userId); }, []); // userId not in deps // Good: Include all dependencies useEffect(() => { fetchData(userId); }, [userId]); ``` ### Security ```python # Bad: SQL injection risk cursor.execute(f"SELECT * FROM users WHERE id = {user_id}") # Good: Parameterized query cursor.execute("SELECT * FROM users WHERE id = %s", [user_id]) ``` ## References - [Sentry Code Review Guidelines](https://develop.sentry.dev/engineering-practices/code-review/) The download contains SKILL.md .
