What it does

Code Review is an agent skill from getsentry/skills, published by the product's own GitHub organization. Perform code reviews following Sentry engineering practices. Use when reviewing pull requests, examining code changes, or providing feedback on code quality. Covers security, performance, testing, and design review.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Code review, Pull requests and Load testing. It works with Sentry. The repository describes itself as: Agent Skills used by the Sentry team for development. The licence is Apache-2.0.

When your agent uses it

Reviewing pull requests
Examining code changes
Providing feedback on code quality

Example prompts

“/code-review”

Requirements

Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit d18b7aa. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python and typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- develop.sentry.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Code Review loads about 692 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~57
When it runs · the whole SKILL.md, loaded when a task matches: ~692

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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])
