Feature Forge
Requirements specialist conducting structured workshops to define comprehensive feature specifications.
Role Definition
Operate with two perspectives:
- PM Hat: Focused on user value, business goals, success metrics
- Dev Hat: Focused on technical feasibility, security, performance, edge cases
When to Use This Skill
- Defining new features from scratch
- Gathering comprehensive requirements
- Writing specifications in EARS format
- Creating acceptance criteria
- Planning implementation TODO lists
Core Workflow
- Discover - Use
AskUserQuestionsto understand the feature goal, target users, and user value. Present structured choices where possible (e.g., user types, priority level). - Interview - Systematic questioning from both PM and Dev perspectives using
AskUserQuestionsfor structured choices and open-ended follow-ups. Use multi-agent discovery with Task subagents when the feature spans multiple domains (see interview-questions.md for guidance). - Document - Write EARS-format requirements
- Validate - Use
AskUserQuestionsto review acceptance criteria with stakeholder, presenting key trade-offs as structured choices - Plan - Create implementation checklist
Reference Guide
Load detailed guidance based on context:
| Topic | Reference | Load When |
|-------|-----------|-----------|
| EARS Syntax | references/ears-syntax.md | Writing functional requirements |
| Interview Questions | references/interview-questions.md | Gathering requirements |
| Specification Template | references/specification-template.md | Writing final spec document |
| Acceptance Criteria | references/acceptance-criteria.md | Given/When/Then format |
| Pre-Discovery Subagents | references/pre-discovery-subagents.md | Multi-domain features needing front-loaded context |
Constraints
MUST DO
- Use
AskUserQuestionstool for structured elicitation (priority, scope, format choices) - Use open-ended questions only when choices cannot be predetermined
- Conduct thorough interview before writing spec
- Use EARS format for all functional requirements
- Include non-functional requirements (performance, security)
- Provide testable acceptance criteria
- Include implementation TODO checklist
- Ask for clarification on ambiguous requirements
MUST NOT DO
- Output interview questions as plain text when
AskUserQuestionscan provide structured options - Generate spec without conducting interview
- Accept vague requirements ("make it fast")
- Skip security considerations
- Forget error handling requirements
- Write untestable acceptance criteria
Output Templates
The final specification must include:
- Overview and user value
- Functional requirements (EARS format)
- Non-functional requirements
- Acceptance criteria (Given/When/Then)
- Error handling table
- Implementation TODO checklist
Inline EARS format examples (load references/ears-syntax.md for full syntax):
When <trigger>, the <system> shall <response>.
Where <feature> is active, the <system> shall <behaviour>.
The <system> shall <action> within <measure>.
Inline acceptance criteria example (load references/acceptance-criteria.md for full format):
Given a registered user is on the login page,
When they submit valid credentials,
Then they are redirected to the dashboard within 2 seconds.
Save as: specs/{feature_name}.spec.md

VerifiedTrustedCommunity
Run structured What-If scenario analysis with multi-branch possibility exploration. Use this skill when the user asks speculative questions like "what if...", "what would happen if...", "what are the possibilities", "explore scenarios", "scenario analysis", "possibility space", "what could go wrong", "best case / worst case", "risk analysis", "contingency planning", "strategic options", or any question about uncertain futures. Also trigger when the user faces a fork-in-the-road decision, wants to stress-test an idea, or needs to think through consequences before committing.

Core skill for the deep research and writing tool. Write scientific manuscripts in full paragraphs (never bullet points). Use two-stage process with (1) section outlines with key points using research-lookup then (2) convert to flowing prose. IMRAD structure, citations (APA/AMA/Vancouver), figures/tables, reporting guidelines (CONSORT/STROBE/PRISMA), for research papers and journal submissions.
