Quality

Perf Theory Tester runs controlled performance experiments to validate hypotheses. Use it when you need to apply a single change, run multiple validation passes, and record evidence against a baseline.

Performance Code Paths identifies likely implementation paths for a performance scenario, mapping entrypoints and hot files before profiling. Use it to narrow down the most relevant 10-15 files in Rust, Java, JS/TS, Go, or Python codebases.

Code Review assesses design, correctness, maintainability, and test coverage of a codebase or change and gives actionable feedback. Use when asked to review a project or diff, or when the /review command runs.

Vuln Check scans a project for known vulnerable dependencies and security anti-patterns, reports findings ordered by severity with location, impact, and remediation, and states explicitly when categories are clean.

Bug Report captures a reported bug and produces a structured, actionable bug report after asking only minimal clarifying questions. Use it when a user reports a bug or asks to capture one.

Code Audit scans a codebase for security, correctness, and quality issues and reports them organized by severity. Use it when asked to audit a project or when the /audit command runs.

Programming Practice runs interactive programming practice sessions with the user, adapting difficulty to their level and goals. Use it when the user asks to practice programming or wants to level up a specific skill through guided exercises.

Pull Request Comments Review fetches and analyzes pull request review comments on the current branch, groups them by theme, and summarizes actionable items so a developer can address feedback.

C++ Coding Standards provides a set of rules and best practices based on the C++ Core Guidelines for writing modern, safe, and idiomatic C++ code. Use it when writing, reviewing, or refactoring C++ code to enforce type safety, resource safety, immutability, and clarity.

C++ Testing guides writing and debugging C++17/20 tests with GoogleTest/Mock, CMake/CTest, coverage, and sanitizers. Use it when creating or fixing C++ tests, configuring CI test gates, or diagnosing flaky failures.

Coding Standards provides general coding standards, best practices, and patterns for TypeScript, JavaScript, React, and Node.js development. Use it when starting new projects, reviewing code, refactoring, or enforcing consistency in naming, formatting, and architecture.

Django Security provides best practices for securing Django applications, covering authentication, authorization, CSRF protection, SQL injection prevention, XSS prevention, and secure deployment configuration. Use it when setting up Django authentication, implementing permissions, configuring production settings, or reviewing security.
