+description: Guided feature development with codebase understanding and architecture focus
+---
+
+A structured feature-development workflow that emphasizes understanding existing code before writing new code.
+
+## Phases
+
+### 1. Discovery
+
+- read the feature request carefully
+- identify requirements, constraints, and acceptance criteria
+- ask clarifying questions if the request is ambiguous
+
+### 2. Codebase Exploration
+
+- use `code-explorer` to analyze the relevant existing code
+- trace execution paths and architecture layers
+- understand integration points and conventions
+
+### 3. Clarifying Questions
+
+- present findings from exploration
+- ask targeted design and edge-case questions
+- wait for user response before proceeding
+
+### 4. Architecture Design
+
+- use `code-architect` to design the feature
+- provide the implementation blueprint
+- wait for approval before implementing
+
+### 5. Implementation
+
+- implement the feature following the approved design
+- prefer TDD where appropriate
+- keep commits small and focused
+
+### 6. Quality Review
+
+- use `code-reviewer` to review the implementation
+- address critical and important issues
+- verify test coverage
+
+### 7. Summary
+
+- summarize what was built
+- list follow-up items or limitations
+- provide testing instructions

+description: Comprehensive PR review using specialized agents
+---
+
+Run a comprehensive multi-perspective review of a pull request.
+
+## Usage
+
+`/review-pr [PR-number-or-URL] [--focus=comments|tests|errors|types|code|simplify]`
+
+If no PR is specified, review the current branch's PR. If no focus is specified, run the full review stack.
+
+## Steps
+
+1. Identify the PR:
+   - use `gh pr view` to get PR details, changed files, and diff
+2. Find project guidance:
+   - look for `CLAUDE.md`, lint config, TypeScript config, repo conventions
+3. Run specialized review agents:
+   - `code-reviewer`
+   - `comment-analyzer`
+   - `pr-test-analyzer`
+   - `silent-failure-hunter`
+   - `type-design-analyzer`
+   - `code-simplifier`
+4. Aggregate results:
+   - dedupe overlapping findings
+   - rank by severity
+5. Report findings grouped by severity
+
+## Confidence Rule
+
+Only report issues with confidence >= 80:
+
+- Critical: bugs, security, data loss
+- Important: missing tests, quality problems, style violations
+- Advisory: suggestions only when explicitly requested
