Agent
Conditional document-review persona for high-stakes documents -- those with significant architectural decisions, new abstractions, or more than 5 requirements. Challenges premises, surfaces unstated assumptions, and stress-tests decisions rather than evaluating document quality.
Agent
Conditional code-review persona, selected when the diff is large (>=50 changed lines) or touches high-risk domains like auth, payments, data mutations, or external APIs. Actively constructs failure scenarios to break the implementation rather than checking against known patterns.
Agent
Reviews code to ensure agent-native parity -- any action a user can take, an agent can also take. Use after adding UI features, agent tools, or system prompts.
Agent
Conditional code-review persona, selected when the diff touches API routes, request/response types, serialization, versioning, or exported type signatures. Reviews code for breaking contract changes.
Agent
Analyzes code changes from an architectural perspective for pattern compliance and design integrity. Use when reviewing PRs, adding services, or evaluating structural refactors.
Agent
Researches and synthesizes external best practices, documentation, and examples for any technology or framework. Use when you need industry standards, community conventions, or implementation guidance.
Agent
Final review pass to ensure code is as simple and minimal as possible. Use after implementation is complete to identify YAGNI violations and simplification opportunities.
Agent
Reviews planning documents for internal consistency -- contradictions between sections, terminology drift, structural issues, and ambiguity where readers would diverge. Spawned by the document-review skill.
Agent
Always-on code-review persona. Reviews code for logic errors, edge cases, state management bugs, error propagation failures, and intent-vs-implementation mismatches.
Agent
Reviews database migrations, data models, and persistent data code for safety. Use when checking migration safety, data constraints, transaction boundaries, or privacy compliance.
Agent
Validates data migrations, backfills, and production data transformations against reality. Use when PRs involve ID mappings, column renames, enum conversions, or schema changes.
Agent
Conditional code-review persona, selected when the diff touches migration files, schema changes, data transformations, or backfill scripts. Reviews code for data integrity and migration safety.
Agent
Produces Go/No-Go deployment checklists with SQL verification queries, rollback procedures, and monitoring plans. Use when PRs touch production data, migrations, or risky data changes.
Agent
Visually compares live UI implementation against Figma designs and provides detailed feedback on discrepancies. Use after writing or modifying HTML/CSS/React components to verify design fidelity.
Agent
Iteratively refines UI design through N screenshot-analyze-improve cycles. Use PROACTIVELY when design changes aren't coming together after 1-2 attempts, or when user requests iterative refinement.
Agent
Reviews planning documents for missing design decisions -- information architecture, interaction states, user flows, and AI slop risk. Uses dimensional rating to identify gaps. Spawned by the document-review skill.
Agent
Conditional code-review persona, selected when Rails diffs introduce architectural choices, abstractions, or frontend patterns that may fight the framework. Reviews code from an opinionated DHH perspective.
Agent
Evaluates whether proposed technical approaches in planning documents will survive contact with reality -- architecture conflicts, dependency gaps, migration risks, and implementability. Spawned by the document-review skill.
Agent
Detects and fixes visual differences between a web implementation and its Figma design. Use iteratively when syncing implementation to match Figma specs.
Agent
Gathers comprehensive documentation and best practices for frameworks, libraries, or dependencies. Use when you need official docs, version-specific constraints, or implementation patterns.
Agent
Performs archaeological analysis of git history to trace code evolution, identify contributors, and understand why code patterns exist. Use when you need historical context for code changes.
Agent
Fetches and analyzes GitHub issues to surface recurring themes, pain patterns, and severity trends. Use when understanding a project's issue landscape, analyzing bug patterns for ideation, or summarizing what users are reporting.
Agent
Conditional code-review persona, selected when the diff touches async UI code, Stimulus/Turbo lifecycles, or DOM-timing-sensitive frontend behavior. Reviews code for race conditions and janky UI failure modes.
Agent
Conditional code-review persona, selected when the diff touches Python code. Reviews changes with Kieran's strict bar for Pythonic clarity, type hints, and maintainability.
