Implement a feature documented in the SPF feature registry. Consumes a feature doc at internal/design/spf/features/<name>.md and produces the engine-side code: new behaviors, updates to existing behaviors, media-layer / network-layer primitives, and tests. The implementation analog of /spf-document-feature (which produces the doc; this consumes it). Walks through resolving the doc's open questions before coding, maps phases to discrete chunks, applies the SPF conventions catalog, routes to downstream skills (/spf-create-behavior, /spf-update-behavior, /refactor-behavior) per chunk shape, and updates the feature doc's Status / Implementation surface / Verification sections as code lands. Triggers: "implement feature", "implement SPF feature", "build feature", "code feature", "scope feature implementation", "implement <feature-name>".
Create a new SPF behavior with conventions-aligned shape. Walks through purpose articulation (carries /refactor-behavior's purpose-first discipline), signal type choice, slot map design, composition placement, cleanup pattern selection, test placement, and engine wiring. Distinct from /refactor-behavior (which modifies an existing behavior preserving its purpose) and /spf-update-behavior (which modifies an existing behavior whose purpose is changing). Triggers: "create behavior", "new behavior", "create SPF behavior", "add behavior", "scaffold behavior", "new SPF behavior".
Produce or update an entry in the SPF use-case-composition registry at internal/design/spf/use-cases/. Triangulates context from multiple sources (Notion, GitHub, pasted writeups, existing use-case docs, constituent feature docs, codebase), grounds the use case in the four composition mechanisms (subtract / add / alternative-impl / alternative-default-config), applies use-case-specific cross-cutting concern checks, drafts the doc at the appropriate definition depth, and cascades narrow updates to constituent feature docs and sibling use cases. Triggers: "document use case", "register use case", "use case doc", "update use case doc", "deepen use-case stub", "new SPF use case", "use case composition", "draft use-case registry entry", "new use case composition".
Implement a use-case composition documented in the SPF use-case-composition registry. Consumes a use-case doc at internal/design/spf/use-cases/<name>.md and produces the engine-side code: a variant engine factory, a parallel adapter, composition wiring, use-case-specific behaviors (if any), and tests. The implementation analog of /spf-document-use-case (which produces the doc; this consumes it). Walks through disambiguation + routing (verify the request is actually a use case, check constituent-feature implementation status), resolves the doc's open questions with the user, maps phases to chunks, routes to downstream skills (/spf-implement-feature for unimplemented constituents, /spf-create-behavior, /spf-update-behavior, /refactor-behavior), and updates both the use-case doc and constituent feature docs as code lands. Treats the use-case doc as a starting point for planning, not a hardened specification. Triggers: "implement use case", "implement SPF use case", "implement use-case composition", "build use ca
Update an existing SPF behavior whose purpose is changing or expanding. Distinct from /refactor-behavior, which preserves purpose — this skill handles cases where the behavior gains new responsibility (new state slot to react to, new lifecycle phase, new constraint, new code path). Carries /refactor-behavior's purpose-first discipline applied to the *purpose change*. Triggers: "update behavior", "extend behavior", "modify behavior", "change behavior purpose", "expand behavior responsibility".
Produce or update an entry in the SPF feature registry at internal/design/spf/features/. Triangulates context from multiple sources (Notion, GitHub, pasted writeups, existing feature docs, codebase), grounds the feature in the cluster heuristics, applies cross-cutting concern checks, drafts the doc at the appropriate definition depth, and cascades narrow updates to related feature docs. Triggers: "document feature", "register feature", "feature doc", "update feature doc", "deepen feature stub", "draft feature registry entry", "new SPF feature".
