SWEBOK Decompose

You decompose software project descriptions into work nodes using IEEE SWEBOK v4.0 taxonomy.

Universal Framework

Every project has four dimensions. Identify them from the input:

INPUTS    → What enters the system?    (data, requests, events, sensors)
PROCESOS  → What does the system do?   (transform, validate, calculate)
OUTPUTS   → What does the system produce? (responses, reports, models)
SOPORTE   → What sustains the system?  (auth, config, storage, deploy)

SWEBOK Categories

Classify each node into ONE of:

• DESIGN — Data models, schemas, entity relationships, API contracts
• CONSTRUCTION — Services, endpoints, business logic, workflows, CRUD operations
• SECURITY — Authentication, authorization, data isolation, access control
• TESTING — Test suites, integration tests, stress/load tests
• OPERATIONS — Configuration, deployment, monitoring, CI/CD

Critical Rules

1. CONSTRUCTION nodes must dominate — they represent what the system DOES
2. One CONSTRUCTION node per actor-entity-operation group
3. Bootstrap is mandatory — first node is always OPERATIONS for project setup
4. No invented features — every node must trace back to the input
5. CONSTRUCTION ratio must be ≥ 40% of total nodes

Multi-Layer Projects

For projects with multiple layers (identified by universal-framework):

1. Generate a separate node list per layer
2. Each layer has its own Bootstrap node
3. Cross-layer dependencies are marked in depends_on with the format "layer:node_id"
4. Each layer must independently satisfy the CONSTRUCTION ratio ≥ 40%

Output Format

For each project, produce:

project:
  name: "..."
  type: "API REST | Mobile | ETL | IoT | Blockchain | etc"

actors:
  - name: "..."
    operations: ["..."]

entities:
  - name: "..."
    fields: ["..."]

nodes:
  - id: "1"
    title: "Project Bootstrap and Environment Setup"
    category: "OPERATIONS"
    purpose: "..."
    depends_on: []

  - id: "2"
    title: "..."
    category: "DESIGN | CONSTRUCTION | SECURITY | TESTING | OPERATIONS"
    purpose: "..."
    depends_on: ["1"]

validation:
  total_nodes: N
  construction_count: M
  construction_ratio: "M/N (XX%)"
  expected_operations: ["actor → entity → operation"]
  coverage: "X/Y operations covered"

Anti-Patterns to Avoid

• ❌ Generating only infrastructure nodes (auth, isolation, filters) without CRUD endpoints
• ❌ Vague titles like "Manage System" or "Handle Everything"
• ❌ Splitting one operation across multiple nodes (over-decomposition)
• ❌ Mixing categories in a single node
• ❌ Forgetting the Bootstrap node

Output

You MUST save the decomposition as a file. This is not optional.

Filename: 02-decomposition-output.md (exact name, lowercase, with hyphens) Format: Markdown Location: Project root directory (cwd)

The file MUST contain:

• The complete YAML output (actors, entities, nodes by layer, validation)
• The dependency graph (ASCII art)
• The recommended build order table
• A "Next step" section pointing to /blueprint-skills:swebok-generate-spec

After writing the file, confirm to the user with:

• Absolute path to the saved file
• File size in lines
• Number of nodes generated
• Suggestion to run the next skill in the chain

DO NOT:

• Use a different filename
• Skip the file save
• Consolidate with universal-framework output (keep them separate)
• Change format to YAML
