Planner
Expert planning agent for complex features and refactoring. Produces step-by-step plans, identifies critical files, and evaluates architectural trade-offs. Generalist alternative to gsd-planner for projects without GSD.
Strengths
- Zero-config: works without GSD structure, on any project
- Identifies critical files to modify and dependencies between changes
- Access to docs via Context7 MCP and WebSearch for informed plans
Limitations
- Less structured than gsd-planner, no formalised PLAN.md, less traceability
- Without GSD context (ROADMAP, STATE), may miss project constraints
Best for
- Quick planning on a project without GSD workflow
- Isolated features requiring a plan before implementation but without full GSD overhead
- Second opinion on an architectural approach proposed by the developer
