Use this skill to design new products, iterate on product ideas, or develop product specifications. Triggers: "design product", "new product idea", "product concept", "product development", "product spec", "iterate on product", "product design", "invention", "prototype spec", "product requirements", "product engineering", "develop product" Outputs: Product specification, BOM estimate, feature breakdown, differentiation analysis.
Write feature specifications that capture requirements and acceptance criteria. Use when (1) writing a new feature spec, (2) documenting functional requirements, (3) defining acceptance criteria for a feature, (4) capturing design goals and constraints for planned work, or (5) structuring a product idea into a formal specification.
Guide for authoring comprehensive PRDs with parallel planning support. Use for drafting technical specifications, defining requirements, and synthesizing planner outputs. Use proactively when creating PRDs, architecture designs, or implementation plans. Examples: - user: "Draft a PRD for user auth" → create PRD with purpose, requirements, and scenarios - user: "Analyze these PRD requirements" → verify SHALL/MUST usage and scenario structure - user: "Synthesize planner outputs" → merge the strongest parts of multiple generated PRDs - user: "Create a PRD template" → setup standard sections and placeholder content
Guides creation of best-practice agent skills following the open format specification. Covers frontmatter, directory structure, progressive disclosure, reference files, rules folders, and validation. Use when creating a new skill, authoring SKILL.md, setting up a rules-based audit skill, structuring a skill bundle, or asking "how to write a skill."
Archives completed changes and merges specification deltas into living documentation. Use when changes are deployed, ready to archive, or specs need updating after implementation. Triggers include "openspec archive", "archive change", "merge specs", "complete proposal", "update documentation", "finalize spec", "mark as done".
Extract comprehensive JSON design specifications from visual sources including Figma exports, UI mockups, screenshots, or live website captures. Produces W3C DTCG-compliant output with component trees, suitable for code generation, design documentation, and developer handoff.
Download remote OpenAPI JSON to a local file via aptx-ft. This skill applies when users request to fetch Swagger/OpenAPI specifications from a URL, save the spec to openapi.json, or prepare local input for subsequent model or service generation.
Specification generator - 6 phase document chain producing product brief, PRD, architecture, and epics. Triggers on "generate spec", "create specification", "spec generator", "workflow:spec".
Prompt for creating an Epic Product Requirements Document (PRD) for a new epic. This PRD will be used as input for generating a technical architecture specification.
Produces rigorous, unambiguous mathematical specifications using sets, functions, relations, invariants, and explicit edge-case handling. Use when requirements are ambiguous, systems have interacting constraints, or behavior/contracts must be precise and falsifiable.
Implement features from a validated RootSpec specification — test-driven and autonomous. Use this when a user wants to build, code, or implement features from their spec, or when they want to make failing tests pass.
Run tests against a validated RootSpec specification and report results. Use this when a user wants to run tests, check what's passing, get a test report, or verify their implementation works.
