Walden History narrates a Walden repository's past from git history: feature chronicles built from frontmatter transitions, the product story of eras and supersessions, rework reports measuring churn after approvals, and the retirement ceremony for superseded specifications. Use when the user asks how a feature evolved, for a spec timeline or contract history, for rework or churn analysis, for the portfolio's story, or to retire superseded specs from `.walden/specs/`.
Walden drafts and maintains feature specs in `.walden/specs/` with a gated workflow: EARS requirements, design documents, implementation tasks, and execution of approved tasks. Use when the user asks for Walden, a feature spec, requirements, a design doc, an implementation plan, or work from an existing `.walden/specs/` folder.
