supersigil

Use when setting up CI gates, reviewing pull requests, interpreting verification failures, or adding Supersigil checks to automated pipelines. Activates on CI configuration, PR review workflows, and verification output triage.

Default skill for behavior-changing code work in projects that already have Supersigil specs. Use when fixing bugs, adding features, implementing endpoints, updating tests, repairing verification coverage, or completing tasks linked to existing requirement, design, or tasks documents. Works alongside TDD, code review, and language-specific skills.

Default skill for authoring or repairing Supersigil specification documents: requirements, design docs, tasks, and ADRs. Use when turning an agreed feature idea or imported material into verifiable docs, refining acceptance criteria, or bringing specs to an implementation-ready state. Works alongside brainstorming and planning skills.

Use when restructuring code that has Supersigil specs and behavior must not change. Activates for module extraction, file moves, renames, hierarchy flattening, or any structural cleanup. Keeps specs, criteria, tracked files, and verification evidence valid throughout.

Use when code exists but Supersigil specs do not, or when existing specs have gone stale. Activates when the user wants to document current behavior, baseline before a refactor, add spec coverage to a brownfield module, or reconcile drifted specs with the codebase.

Use ONLY when the user explicitly requests the full end-to-end Supersigil workflow — from feature idea through verified specs to implementation. This is the guided "omakase" flow. For just writing specs, use ss-feature-specification. For just implementing, use ss-feature-development.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
