plannar

Use when the user asks for a plan, design doc, proposal, or implementation breakdown. Plannar writes plans as MDX files in `.plannar/plans/` using shadcn/ui components (Tabs, Accordion, Cards) and interactive Playground previews so the output is skimmable and token-efficient instead of a wall of markdown. Covers the full workflow — explore the codebase, design with Plan agents, review, then author the MDX — plus shadcn component usage, Playground state bindings, and `.plannar` config.

Changesets for versioning and changelog management in monorepos. Use when managing package versions, generating changelogs, or publishing packages. Use for changesets, versioning, changelog, semver, monorepo-versioning, release, publish, bump.
