--- name: feature-forge description: Conducts structured requirements workshops to produce feature specifications, user stories, EARS-format functional requirements, acceptance criteria, and implementation checklists. Use when defining new features, gathering requirements, or writing specifications. Invoke for feature definition, requirements gathering, user stories, EARS format specs, PRDs, acceptance criteria, or requirement matrices. license: MIT metadata: author: https://github.com/Jeffallan version: "1.1.0" domain: workflow triggers: requirements, specification, feature definition, user stories, EARS, planning role: specialist scope: design output-format: document related-skills: fullstack-guardian, spec-miner, test-master --- # 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 1. **Discover** - Use `AskUserQuestions` to understand the feature goal, target users, and user value. Present structured choices where possible (e.g., user types, priority level). 2. **Interview** - Systematic questioning from both PM and Dev perspectives using `AskUserQuestions` for 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). 3. **Document** - Write EARS-format requirements 4. **Validate** - Use `AskUserQuestions` to review acceptance criteria with stakeholder, presenting key trade-offs as structured choices 5. **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 `AskUserQuestions` tool 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 `AskUserQuestions` can 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: 1. Overview and user value 2. Functional requirements (EARS format) 3. Non-functional requirements 4. Acceptance criteria (Given/When/Then) 5. Error handling table 6. 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` [Documentation](https://jeffallan.github.io/claude-skills/skills/workflow/feature-forge/)

1. **Prepare the Workshop**: Gather stakeholders with [STAKEHOLDER ROLES] (e.g., product managers, developers, end-users). Share the prompt template with them 24 hours in advance to collect initial inputs. Use a tool like Miro or Lucidchart for collaborative brainstorming. 2. **Run the Session**: Use the prompt to guide a 60-90 minute workshop. Start with a 10-minute icebreaker to align on the feature’s purpose. Then, follow the structured steps: brainstorm needs, organize requirements, and convert them into EARS format. Capture outputs in a shared document (e.g., Google Docs, Notion). 3. **Prioritize and Validate**: Apply the MoSCoW method to prioritize requirements. For each user story, validate acceptance criteria with end-users in real-time. Use tools like Trello or Jira to track progress and assign owners. 4. **Generate the Deliverables**: After the session, use the prompt to generate the PRD, requirement matrix, and implementation checklist. Share these with the team for review and iterate based on feedback. Use tools like Confluence or Notion to store the final package. 5. **Follow Up**: Schedule a 30-minute review session 1 week later to address any gaps or new requirements. Use the outputs to create tickets in your project management tool (e.g., Jira, Azure DevOps) and assign them to the development team.
