# Specification Writer Skill

**Version:** 1.1
**Created:** 2026-02-02
**Updated:** 2026-02-16
**Author:** Manus
**Purpose:** Write production-ready, A+ quality specifications for software releases

---

## Overview

This skill encodes the pattern for writing comprehensive, technically rigorous specifications that match the quality of Dojo Genesis v0.0.17-v0.0.23. Use this skill when creating specifications for new features, releases, or system components.

**Quality Standard:** 111/100 (A+)

---

## When to Use This Skill

- Creating specifications for new software versions or releases
- Documenting complex system architectures
- Planning major feature implementations
- Communicating technical vision to development teams
- Ensuring consistency across multiple specifications

---

## Choosing the Right Format

The specification template is a **maximum, not a default**. Calibrate your format to the scope, audience, and context. Use the appropriate tier:

### Full Template: Strategic & Architectural Specs

**Use for:** Complex systems, new architectures, major releases, multi-component integrations, high-risk decisions

**Includes:** Vision, goals, success criteria, detailed technical architecture, implementation plan, risk assessment, rollback procedures, monitoring, documentation strategy, appendices

**When to choose:** Your audience includes stakeholders, architects, or future maintainers who need to understand the "why" and "how." The release is substantial enough to warrant comprehensive documentation. Architecture is novel or the system integration is complex.

**Typical length:** 5,000-15,000+ words

### Lean Format: Implementation-Ready Feature Specs

**Use for:** Well-understood features, implementation-scoped work, autonomous agent execution, rapid iteration cycles

**Includes:** Brief context (why this matters), component tables, behavior lists, route/API layouts, code examples, test cases. Skip: preamble, vision section, lengthy risk analysis, extensive documentation strategy

**When to choose:** The feature is well-scoped and the audience is an implementation agent (human developer or AI). The problem is well-understood. You're optimizing for speed and clarity, not stakeholder alignment.

**Typical length:** 1,000-3,000 words

**Structure (sonnet level chunks):**
- **Feature Name & Context** (2-3 sentences)
- **Components Table** (what, where, why)
- **API/Routes Table** (endpoint, method, request, response)
- **Behavior List** (numbered or bulleted behaviors)
- **Implementation Code Blocks** (production-ready examples)
- **Test Cases** (unit, integration, edge cases)
- **Rollout Notes** (if applicable)

### Minimal Format: Incremental Changes & Bug Fixes

**Use for:** Bug fixes, small enhancements, well-established patterns, dependency updates

**Includes:** Delta description (what changed), code examples, test cases, affected components

**When to choose:** The change is localized and low-risk. The implementation pattern is proven. You're optimizing for minimal documentation overhead.

**Typical length:** 200-1,000 words

### Decision Heuristic

Ask yourself:
- **Is the audience an autonomous implementation agent and the feature is well-scoped?** → Use **Lean Format**
- **Do stakeholders need to understand the vision and architecture is novel?** → Use **Full Template**
- **Is this a small, isolated change to a proven pattern?** → Use **Minimal Format**
- **Uncertain?** Lean toward the **Full Template** to ensure completeness

2. [Specific, measurable goal]
3. [Specific, measurable goal]

**Success Criteria:**
- ✅ [Concrete, testable criterion]
- ✅ [Concrete, testable criterion]
- ✅ [Concrete, testable criterion]

**Non-Goals (Out of Scope):**

```

### Part 2: Technical Architecture (40-50% of document)

```markdown
## 3. Technical Architecture

### 3.1 System Overview

[High-level diagram or description of how components fit together]

**Key Components:**
1. **[Component Name]** - [Purpose and responsibility]
2. **[Component Name]** - [Purpose and responsibility]
3. **[Component Name]** - [Purpose and responsibility]

### 3.2 [Feature/Component 1] - Detailed Design

**Purpose:** [What this component does and why it's needed]

**Architecture:**

[Detailed explanation with diagrams if helpful]

**Backend Implementation (Go):**

```go
// Complete, production-ready code example
package [package_name]

type [StructName] struct {
    Field1 string `json:"field1"`
    Field2 int    `json:"field2"`
}

func (s *[StructName]) [MethodName]() error {
    // Implementation with error handling
    return nil
}
```

**Frontend Implementation (React/TypeScript):**

```typescript
// Complete, production-ready code example
interface [InterfaceName] {
  field1: string;
  field2: number;
}

export const [ComponentName]: React.FC<Props> = ({ prop1, prop2 }) => {
  const [state, setState] = useState<StateType>(initialState);

  // Implementation

  return (
    <div className="...">
      {/* JSX */}
    </div>
  );
};
```

**API Endpoints:**

| Method | Endpoint | Request | Response | Purpose |
|--------|----------|---------|----------|---------|
| POST | `/api/v1/[resource]` | `{ field: value }` | `{ id: string }` | [Description] |
| GET | `/api/v1/[resource]/:id` | - | `{ data: object }` | [Description] |

**Database Schema (if applicable):**

```sql
CREATE TABLE [table_name] (
    id TEXT PRIMARY KEY,
    field1 TEXT NOT NULL,
    field2 INTEGER DEFAULT 0,

);

CREATE INDEX idx_[field] ON [table_name]([field]);
```

**Integration Points:**

## Common Pitfalls to Avoid

❌ **Vague Goals:** "Improve user experience" → ✅ "Reduce context loading time by 50%"
❌ **Missing Code Examples:** High-level description only → ✅ Complete, runnable code
❌ **Unrealistic Timelines:** "2 days for full backend" → ✅ "2 weeks with phased approach"
❌ **No Risk Assessment:** Assumes everything will work → ✅ Identifies risks and mitigations
❌ **Incomplete Testing:** "We'll test it" → ✅ Specific test cases and coverage targets
❌ **No Integration Points:** Treats feature as isolated → ✅ Documents how it connects to existing system
❌ **Using Full Template for Well-Scoped Features:** Wastes tokens and delays commissioning → ✅ Use lean format for autonomous implementation agents with clear scope

---

## Usage Instructions

1. **Assess scope and audience** before choosing format
2. **Select the appropriate format tier** (Full Template, Lean, or Minimal)
3. **Copy the relevant template structure** to your new document
4. **Fill in each section** with specific, detailed content
5. **Run the quality checklist** before finalizing (including format alignment)
6. **Study example specifications** for patterns and depth
7. **Iterate** until every checklist item is ✅

---

## Skill Metadata

**Token Savings:** ~10,000-15,000 tokens per full spec; ~2,000-5,000 per lean spec (adaptive format efficiency)
**Quality Impact:** Ensures consistency across all specifications while optimizing for context
**Maintenance:** Update when new patterns emerge from successful releases
