What problem does it solve? Jumping straight into code without a vetted plan leads to wrong assumptions about existing code, over-engineering, and missed edge cases. This Skill enforces a disciplined workflow: draft a phased plan, have four independent review lenses attack it against the actual codebase, then implement one verified phase at a time. ## Core Features & Use Cases - Structured Planning: Researches requirements (including GitHub issues via gh), technology versions, and existing architecture, then produces a phased plan with file structure, risks, and verification steps. - Parallel Review Council: Fans the draft plan out to four concurrent subagent lenses (codebase reality-check, architecture & ripple, simplicity & reuse, edge cases & states) that return severity-tagged findings with file:line evidence. - Reflex-Driven Implementation: Implements phase-by-phase in the main session using a reflex checklist mapped to project rules (guard clauses, nx: Tailwind tokens, Storybook story tests, ripple-effect sweeps), with mandatory typecheck, lint, and commit after each phase. - Use Case: Given GitHub issue #42 requesting a new Dialog size variant, the Skill drafts a phased plan, the council catches that an existing size helper already covers the case, the plan is revised, and each phase is implemented, verified, and committed in sequence. ## Quick Start Ask the agent to plan and implement the feature described in GitHub issue 42 using the implement-guide workflow.
