Creates frontend ADR and Design Docs to evaluate React technical choices. Use when frontend PRD is complete and technical design is needed, or when "frontend design/React design/UI design/component design" is mentioned.

Creates ADR and Design Docs to evaluate technical choices and implementation approaches. Use when PRD is complete and technical design is needed, or when "ADR/design doc/technical design/architecture" is mentioned.

Gathers UI-related facts by reading the project's external-resources file, fetching external sources (design origin, design system, guidelines) via MCP or URL, and analyzing the existing UI codebase. Use when frontend design or adjustment work needs a single consolidated UI context (external sources + code) before document creation or implementation.

Creates UI Specifications from PRD and optional prototype code. Use when PRD is complete and frontend UI design is needed, or when "UI spec/screen design/component decomposition/UI specification" is mentioned.

Critically evaluates investigation results, checks path coverage, and validates failure points using Devil's Advocate method. Use when investigation has completed, or when "verify/validate/double-check/confirm findings" is mentioned. Focuses on verification and conclusion derivation.

Creates work plan documents with trackable execution plans. Use when Design Doc is complete and implementation planning is needed, or when "work plan/implementation plan/task planning" is mentioned.

Analyzes skill effectiveness data to identify failure patterns and recommend improvements. Use after /skill-monitor flags underperforming skills.

Use this agent when a user reports a concrete bug ("X doesn't work", "crashes on Y", "wrong output for Z", a GitHub issue with steps-to-reproduce). The agent reproduces the bug, locates the root cause, applies a minimal fix, proves the fix works with a regression test, and confirms nothing else broke. Do NOT use for feature requests, refactors, or open-ended "look at this code" asks — those are different profiles.

Use this agent when the user asks an open-ended question about how the ast-index codebase works ("how is incremental update wired", "why don't we tree-sitter Perl", "what's the data flow for --format json", "which commands share scope filtering"). The agent reads the code, traces connections, and returns a structured answer with file:line citations. It does NOT edit code, does NOT run destructive commands, and does NOT speculate — every claim is grounded in a file you can open.

Use this agent to review a set of changes before they ship — staged/unstaged diff, a specific commit range, a PR description, or "the latest commit". The agent reads the diff against project rules in CLAUDE.md and .claude/rules/*, runs the build and test suite, and reports what's good, what's wrong, and what's missing. It does NOT fix anything itself — the point is feedback, not rework.
