Tech Spec Phase Skill

Purpose: design the technical solution - a blueprint developers follow without ambiguity.

Entry: PRD approved, requirements clear, dependencies identified. Exit: tech spec complete, architecture documented, API contracts defined, data models specified.

Deliverables

  1. Tech Spec Document - Implementation-ready design
  2. Architecture Diagram - Components and interactions
  3. API Contracts - Endpoints, schemas, errors
  4. Data Models - Schemas, types, constraints

Common Pitfalls

PitfallFix
Over-engineeringDesign for current needs
Missing error handlingDefine errors upfront
Tight couplingDesign for testability
Ignoring non-functionalsAddress performance, security
Unclear contractsAPIs unambiguous with examples

Phase Gate Checklist

  • Tech spec complete
  • Architecture diagram created
  • All API contracts defined
  • Data models specified
  • Error handling strategy defined
  • Security considerations addressed
  • Performance requirements addressed
  • Tech lead approved

Tech Spec Template

Emit these 8 sections, in this order, with these exact headings:

# [Feature] Technical Specification

## 1. Overview
### Problem Summary
### Proposed Solution
### Key Decisions
| Decision | Choice | Rationale |

## 2. Architecture
### System Diagram
[Mermaid or image]

### Component Breakdown
| Component | Responsibility | Dependencies |

### Data Flow

## 3. API Design
### POST /api/[resource]
**Request:**
```json
{ "field": "type" }
```

**Response (200):**
```json
{ "id": "string" }
```

**Errors:**
| Code | Error | Description |

## 4. Data Model
### Entity: [Name]
| Field | Type | Constraints | Description |

## 5. Security
### Authentication
### Authorization
### Data Protection

## 6. Error Handling
| Scenario | Response | Recovery |

## 7. Non-Functional Requirements
| Requirement | Target | Measurement |

## 8. Risks & Mitigations
| Risk | Impact | Mitigation |

Role Guidance

RoleFocus
PMValidate approach addresses requirements
DevOwn spec, design for testability
QAReview testability, integration points
Tech LeadReview architecture, approve direction

Handoff to Implementation

  • Approved tech spec
  • API contracts
  • Data models
  • Architecture decisions with rationale
  • Spike/POC results (if any)
