Interview

Structured requirements gathering that produces a specification document. This skill guides a conversational interview to fully extract and understand what needs to be built before any implementation begins.

When to Use

Use this skill when:

• •Starting work on a new feature or change
• •User mentions an issue number they want to work on
• •User says "interview me", "let's start", "new feature", or "requirements"
• •Beginning any non-trivial implementation task

Instructions

Step 1: Issue Intake (if applicable)

If the user provides a GitHub issue number:

1. •Fetch the issue using gh issue view {number}
2. •Extract title and description as seed context
3. •Acknowledge: "I've read issue #{number}: {title}. Let me ask some questions to fully understand what we're building."

If no issue number, proceed directly to interview.

Step 2: Problem Framing

Ask these questions (adapt based on context):

1. •

   What problem are we solving?

   • •Get the core problem in 1-2 sentences
   • •If vague, ask "Can you give me a concrete example of when this problem occurs?"
2. •

   Why does this matter now?

   • •Understand urgency and priority
   • •"What happens if we don't solve this?"
3. •

   Who benefits?

   • •Identify the user/persona affected
   • •"Who will use this feature?"

Capture responses in the Problem Statement section.

Step 3: Requirements Extraction

Ask these questions:

1. •

   What does "done" look like?

   • •Get specific, observable outcomes
   • •"If this worked perfectly, what would a user see/experience?"
2. •

   How would we test that?

   • •Convert outcomes to testable criteria
   • •"How would we verify this is working correctly?"
3. •

   Are there edge cases to consider?

   • •Boundary conditions, error states
   • •"What should happen if X fails or Y is empty?"
4. •

   Classify each criterion by Test Type:

   • •Unit - Can test with isolated code, mocks OK
   • •Integration - Requires real DB/services (edge functions, DB tests)
   • •Manual - Cannot automate (external APIs, visual, UX) → QA checklist

   Ask: "For [criterion], can we write an automated test, or is this something QA verifies manually?"

Write criteria that are assessable, not just testable. An implementer should be able to objectively determine whether each criterion is satisfied. Avoid vague phrasing like "handles errors appropriately" — instead say what should happen: "Returns 400 with message 'Email required' when email field is empty."

Capture as Acceptance Criteria table with Test Type column. Example:

Step 4: Scope Fencing

Ask these questions:

1. •

   What are we NOT doing?

   • •Explicit exclusions prevent gold-plating
   • •"Is there anything related that we should explicitly leave out?"
2. •

   What's out of scope for this iteration?

   • •Future work vs. current work
   • •"Any nice-to-haves we should defer?"

Capture in Non-Goals section.

Step 5: Security Considerations

Ask these questions:

1. •

   Does this feature handle sensitive data?

   • •User PII, credentials, financial data, tokens
   • •"What data does this feature read, write, or expose?"
2. •

   What authentication/authorization is needed?

   • •Who should be able to access this?
   • •"Should this be admin-only, user-specific, or public?"
3. •

   Are there input validation concerns?

   • •User-provided data that reaches the database or is displayed
   • •"What user input does this accept? Where does it go?"
4. •

   Any RLS/database security implications? (for Supabase projects)

   • •New tables need RLS policies
   • •Existing RLS policies may need updates
   • •"Does this add or modify database access patterns?"

Capture in Security Considerations section.

Common security flags to watch for:

• •New API endpoints → need auth checks
• •User input displayed → XSS risk
• •User input in queries → injection risk
• •File uploads → validation needed
• •New database tables → RLS policies required
• •Service role usage → minimize exposure

Step 6: Constraints & Assumptions

Ask these questions:

1. •

   Any technical constraints?

   • •Existing patterns to follow, libraries to use, performance requirements
2. •

   Dependencies?

   • •Does this depend on or block other work?
3. •

   What are we assuming?

   • •Make implicit assumptions explicit
   • •"Are we assuming the user is already logged in?"

Capture in Assumptions & Constraints section.

Step 7: Resolve Open Questions

Review what you've gathered and ask:

1. •Anything unclear that we should clarify now?
2. •Any decisions we need to make before starting?

Document resolved questions.

Step 8: Assemble Specification

1. •

   Create the spec file at Documents/specs/{issue-number}-{slug}-spec.md

   • •If no issue number, use a descriptive slug
   • •Example: Documents/specs/42-dark-mode-spec.md
2. •

   Use the template from Documents/templates/spec-template.md

3. •

   Fill in all sections from the interview:

   • •Problem Statement
   • •Acceptance Criteria (as checkboxes)
   • •Non-Goals
   • •Security Considerations
   • •Assumptions & Constraints
   • •Technical Notes
   • •Open Questions Resolved
4. •

   Set Status to "Draft"

Step 9: Create/Update GitHub Issue

If no issue exists yet, create one. If working from an existing issue, post a comment with the spec summary.

See shared/github-ops.md for issue creation and posting comments.

After creating/updating the issue:

1. •Link issue to spec - Add **Issue:** #{number} to the spec header

Spec stays as Draft until human approves after spec-review.

Step 9.5: Add Issue to Project (MANDATORY)

Every issue MUST be added to the project board. No exceptions.

1. •

   Find the project number:

   • •Check project's CLAUDE.md for Project Number: in GitHub Config
   • •If not documented, ask the user
   • •Document it in the project's CLAUDE.md for future:
     markdown

     ## GitHub Config
     - **Project Number:** {number}
     

2. •

   Add the issue to the project and set status.

See shared/github-ops.md for adding to project and setting status.

1. •Ask iteration and status:

   "Which iteration and status?"

   • •Backlog (not scheduled yet)
   • •Ready (scheduled, waiting to start)
   • •In Progress (starting now)

Fallback: If project board operations fail, provide manual instructions: "Please add issue #{number} to the project board and set it to {status}."

End-of-skill check: See shared/primitive-updates.md. Signals: domain terms or acronyms surfaced during requirements.

Step 10: Handoff

Tell the user:

"Spec is at Documents/specs/{filename}. Review it, then:

/spec-review Documents/specs/{filename}

That will flag any gaps. Once you approve, we pick TDD or direct implementation."

Best Practices

1. •Don't rush - Better to ask one more question than miss a requirement
2. •Use concrete examples - If something is vague, ask for an example
3. •Read back summaries - "So if I understand correctly..." to verify
4. •Challenge assumptions - "Why do we need X?" can reveal unnecessary scope
5. •Keep it conversational - This is a dialogue, not an interrogation

Example

User: "I want to start work on issue #42"

Claude:

1. •Runs gh issue view 42 to get context
2. •"I've read issue #42: Add dark mode toggle. Let me ask some questions..."
3. •Proceeds through interview phases
4. •Creates Documents/specs/42-dark-mode-spec.md
5. •Posts summary comment to issue #42
6. •Adds to project, asks about iteration
7. •Tells user next steps
