How to create & maintain TypeDoc site documentation and the README for Bupkis

name: business-context

Translate stakeholder questions and business objectives into structured requirements and success criteria. Use when framing pilot scope, defining problem statements, and establishing acceptance metrics based on interviews, briefs, or process documentation.

Use when documenting component implementation patterns, internal structure, or hand-off points - enforces NO CODE rule and diagram-first approach for leaf-level C3 documentation

Use when changes affect component organization, technology stack, or cross-container communication - triggered by new components, pattern changes, or needing to map external interfaces to internal components

Use when exploring Context level impact during scoping - system boundaries, actors, cross-container interactions, and high-level concerns

C4 model architecture visualization and documentation

When fetching library documentation, API references, or technical docs for project dependencies via WebFetch, automatically save a copy to the docs/ folder. Also triggers when user pastes documentation or discusses library APIs that should be cached for reference. Every non-stdlib import in the project should have corresponding reference docs cached.

Annotates cell clusters with biological cell type labels using multiple methods: direct assignment, ScType, scCATCH, hitype, or CellTypist. This process is essential for interpreting clustering results by assigning meaningful biological identities to each cluster.
