Inputs

Read only what is needed:

1. Product intent
   • issue, discussion, PRD, roadmap note, founder message
2. Current architecture
   • relevant repo docs, contracts, schemas, routes, existing workflows
3. Existing capability context
   • PRODUCT.md, design docs, RFCs, migration notes, operating-model docs
4. Delivery constraints
   • auth, billing, compliance, rollout, backwards compatibility, performance, review policy

Core Workflow

1. Restate the capability

Compress the ask into one precise statement:

• who the user or operator is
• what new capability exists after this ships
• what outcome changes because of it

If this statement is weak, the implementation will drift.

2. Resolve capability constraints

Extract the constraints that must hold before implementation:

• business rules
• scope boundaries
• invariants
• trust boundaries
• data ownership
• lifecycle transitions
• rollout / migration requirements
• failure and recovery expectations

These are the things that often live only in senior-engineer memory.

3. Define the implementation-facing contract

Produce an SRS-style capability plan with:

• capability summary
• explicit non-goals
• actors and surfaces
• required states and transitions
• interfaces / inputs / outputs
• data model implications
• security / billing / policy constraints
• observability and operator requirements
• open questions blocking implementation

4. Translate into execution

End with the exact handoff:

• ready for direct implementation
• needs architecture review first
• needs product clarification first

If useful, point to the next ECC-native lane:

• project-flow-ops
• workspace-surface-audit
• api-connector-builder
• dashboard-builder
• tdd-workflow
• verification-loop

Output Format

Return the result in this order:

CAPABILITY
- one-paragraph restatement

CONSTRAINTS
- fixed rules, invariants, and boundaries

IMPLEMENTATION CONTRACT
- actors
- surfaces
- states and transitions
- interface/data implications

NON-GOALS
- what this lane explicitly does not own

OPEN QUESTIONS
- blockers or product decisions still required

HANDOFF
- what should happen next and which ECC lane should take it

Good Outcomes

• Product intent is now concrete enough to implement without rediscovering hidden constraints mid-PR.
• Engineering review has a durable artifact instead of relying on memory or Slack context.
