pre-dev-feature	Lightweight 4-gate pre-dev workflow for small features (<2 days)	[feature-name]

I'm running the Small Track pre-development workflow (4 gates) for your feature.

This track is for features that:

• ✅ Take <2 days to implement
• ✅ Use existing architecture patterns
• ✅ Don't add new external dependencies
• ✅ Don't create new data models/entities
• ✅ Don't require multi-service integration
• ✅ Can be completed by a single developer

If any of the above are false, use /ring-pm-team:pre-dev-full instead.

Document Organization

All artifacts will be saved to: docs/pre-dev/<feature-name>/

First, let me ask you about your feature:

Use the AskUserQuestion tool to gather:

Question 1: "What is the name of your feature?"

• Header: "Feature Name"
• This will be used for the directory name
• Use kebab-case (e.g., "user-logout", "email-validation", "rate-limiting")

After getting the feature name, create the directory structure and run the 4-gate workflow:

mkdir -p docs/pre-dev/<feature-name>

Gate 0: Research Phase (Lightweight)

Skill: ring-pm-team:pre-dev-research

Even small features benefit from quick research:

1. Determine research mode (usually modification for small features)
2. Dispatch 3 research agents in PARALLEL (quick mode)
3. Save to: docs/pre-dev/<feature-name>/research.md
4. Get human approval before proceeding

Gate 0 Pass Criteria (Small Track):

• Research mode determined
• Existing patterns identified (if any)
• No conflicting implementations found

Note: For very simple changes, Gate 0 can be abbreviated - focus on checking for existing patterns.

Gate 1: PRD Creation

Skill: ring-pm-team:pre-dev-prd-creation

1. Ask user to describe the feature (what problem does it solve, who are the users, what's the business value)
2. Create PRD document with:
   • Problem statement
   • User stories
   • Acceptance criteria
   • Success metrics
   • Out of scope
3. Save to: docs/pre-dev/<feature-name>/prd.md
4. Run Gate 1 validation checklist
5. Get human approval before proceeding

Gate 1 Pass Criteria:

• Problem is clearly defined
• User value is measurable
• Acceptance criteria are testable
• Scope is explicitly bounded

Gate 2: TRD Creation (Skipping Feature Map)

Skill: ring-pm-team:pre-dev-trd-creation

1. Load PRD from docs/pre-dev/<feature-name>/prd.md
2. Note: No Feature Map exists (small track) - map PRD features directly to components
3. Create TRD document with:
   • Architecture style (pattern names, not products)
   • Component design (technology-agnostic)
   • Data architecture (conceptual)
   • Integration patterns
   • Security architecture
   • NO specific tech products (use "Relational Database" not "PostgreSQL")
4. Save to: docs/pre-dev/<feature-name>/trd.md
5. Run Gate 2 validation checklist
6. Get human approval before proceeding

Gate 2 Pass Criteria:

• All PRD features mapped to components
• Component boundaries are clear
• Interfaces are technology-agnostic
• No specific products named

Gate 3: Task Breakdown (Skipping API/Data/Deps)

Skill: ring-pm-team:pre-dev-task-breakdown

1. Load PRD from docs/pre-dev/<feature-name>/prd.md
2. Load TRD from docs/pre-dev/<feature-name>/trd.md
3. Note: No Feature Map, API Design, Data Model, or Dependency Map exist (small track)
4. Create task breakdown document with:
   • Value-driven decomposition
   • Each task delivers working software
   • Maximum task size: 2 weeks
   • Dependencies mapped
   • Testing strategy per task
5. Save to: docs/pre-dev/<feature-name>/tasks.md
6. Run Gate 3 validation checklist
7. Get human approval

Gate 3 Pass Criteria:

• Every task delivers user value
• No task larger than 2 weeks
• Dependencies are clear
• Testing approach defined

After Completion

Report to human:

✅ Small Track (4 gates) complete for <feature-name>

Artifacts created:
- docs/pre-dev/<feature-name>/research.md (Gate 0) ← NEW
- docs/pre-dev/<feature-name>/prd.md (Gate 1)
- docs/pre-dev/<feature-name>/trd.md (Gate 2)
- docs/pre-dev/<feature-name>/tasks.md (Gate 3)

Skipped from full workflow:
- Feature Map (features simple enough to map directly)
- API Design (no new APIs)
- Data Model (no new data structures)
- Dependency Map (no new dependencies)
- Subtask Creation (tasks small enough already)

Next steps:
1. Review artifacts in docs/pre-dev/<feature-name>/
2. Use /ring-default:worktree to create isolated workspace
3. Use /ring-default:write-plan to create implementation plan
4. Execute the plan

Remember

• This is the Small Track - lightweight and fast
• Gate 0 (Research) checks for existing patterns even for small features
• If feature grows during planning, switch to /ring-pm-team:pre-dev-full
• All documents saved to docs/pre-dev/<feature-name>/
• Get human approval at each gate
• Technology decisions happen later in Dependency Map (not in this track)
