Design, validate, and plan a startup from scratch. Covers market research, competitive analysis, business model, brand identity, product definition, financial projections, and validation experiments. Trigger when the user has a startup idea to explore, wants to validate a business concept, needs a business plan or lean canvas, asks for market sizing or competitive landscape, wants brand positioning or go-to-market strategy, or says anything like "I have an idea for..." or "is this idea worth pursuing". Also handles resuming from a previous checkpoint.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that hits all the key criteria. It provides comprehensive specificity about capabilities (market research, competitive analysis, business model, etc.), includes natural trigger terms users would actually say, explicitly states when to use it with a 'Trigger when...' clause, and carves out a distinct niche around startup planning and validation. The description uses proper third person voice throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Design, validate, and plan a startup from scratch. Covers market research, competitive analysis, business model, brand identity, product definition, financial projections, and validation experiments.' | 3 / 3 |
Completeness | Clearly answers both what (design, validate, plan startup with specific domains) AND when with explicit 'Trigger when...' clause listing multiple user scenarios and natural language patterns. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'startup idea', 'validate a business concept', 'business plan', 'lean canvas', 'market sizing', 'competitive landscape', 'brand positioning', 'go-to-market strategy', and conversational triggers like 'I have an idea for...' and 'is this idea worth pursuing'. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused specifically on startup planning and validation with distinct triggers around business concepts, startup ideas, and entrepreneurial activities that are unlikely to conflict with other skills. | 3 / 3 |

Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-designed, comprehensive skill for startup validation with excellent workflow clarity and progressive disclosure. The multi-phase structure with checkpoints, resume capability, and explicit validation gates demonstrates sophisticated process design. Minor verbosity in some explanatory sections prevents a perfect conciseness score, but the actionability is exceptional with specific deliverables, file structures, and concrete guidance throughout.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is comprehensive but includes some unnecessary explanation (e.g., explaining what a Lean Canvas is, describing what each phase does conceptually). Some sections could be tightened, though the content is generally efficient for its scope. | 2 / 3 |
Actionability | Highly actionable with specific questions to ask, exact file paths to create, concrete output formats, numbered steps, and detailed templates. The 30-day action plan and experiment designs are copy-paste ready. | 3 / 3 |
Workflow Clarity | Excellent workflow with clear 8-phase sequence, explicit checkpoints (Research Gate, Phase 5/7 confirmations), resume capability via PROGRESS.md, and validation loops throughout. The Fast Track mode provides an alternative path with clear criteria. | 3 / 3 |
Progressive Disclosure | Well-structured with clear overview in main file and explicit references to 10+ supporting files in references/ directory. Each reference file is signaled with 'When to Read' guidance and line counts. Navigation is one level deep and clearly organized. | 3 / 3 |
