Structured first-touch protocol for understanding an existing codebase before contributing to it. Reads the README, ADRs, most-changed and most-recent files, dependency manifests, build/CI config, and test layout, and emits an onboarding cheat-sheet other Aparigraha skills (style-conformance, reuse-first, minimal-diff, chesterton-fence) consume on subsequent tasks.
Adaptive PRD authoring — selects the right format (lean 1-pager, full structured, working backwards, or hypothesis-driven), guides section-by-section completion, and manages document lifecycle with versioning, status transitions, and amendment logging.
