Description

Analyze ESM Artifacts

Guidance

Analyze ESM Artifacts

Objective

Extract capability requirements per architectural domain from the ESM output artifacts (user journey, screen flows, .feature files, IA guidelines). This structured requirements list feeds all subsequent DTA activities (DTA-02 through DTA-17).

Process

1. Read User Journey

• Extract domain entities (e.g., User, Playbook, Workflow, Activity, Skill)
• Identify interaction patterns (CRUD, search, import/export, real-time updates)
• Note personas and roles that imply auth/authorization requirements
• Flag integration points (external systems, APIs, data sources)

2. Read Screen Flows

• Identify UI complexity per screen type:
  • Simple: static content, read-only views
  • Moderate: forms, tables, filters, pagination
  • Complex: graphs, drag-and-drop, real-time, rich text editors
• Count screen types to estimate frontend effort
• Note navigation patterns (breadcrumbs, tabs, modals, wizards)

3. Read Feature Files (.feature)

• Extract required capabilities from scenario steps:
  • CRUD operations per entity
  • Search and filter requirements
  • Authentication and authorization scenarios
  • Error handling and edge cases
  • Data validation rules
• Map scenarios to capability domains (GUI_FORM, API_CRUD, AUTH_SESSION, etc.)

4. Read IA Guidelines

• Extract design system requirements (component library, theming)
• Note accessibility requirements (ARIA, keyboard navigation)
• Identify responsive/multi-device needs

5. Compile Requirements per Domain

Produce a structured list mapping ESM findings to the 16 architectural domains:

Domain: Application Blocks (DTA-02)
  - 5 bounded contexts identified: Auth, Methodology, Planning, MCP, Web UI
  - Dependency: Methodology → Planning (planning reads methodology)

Domain: Integration & API Design (DTA-03)
  - MCP stdio interface required (read-only)
  - Web UI HTTP interface required (full CRUD)
  - No external 3rd party integrations identified

Domain: Code Organization (DTA-04)
  - Monorepo structure implied (single Django project)
  - 3 layers visible: models, services, views

Domain: Data Architecture (DTA-05)
  - 6 entities with relationships (graph-like)
  - Version tracking required
  - Import/export functionality needed

... (continue for all 16 domains)

Deliverables

• ✅ Domain entities extracted from user journey
• ✅ UI complexity assessed from screen flows
• ✅ Capability domains mapped from .feature files
• ✅ Structured requirements list produced for all 16 architectural domains
• ✅ Ready to proceed with DTA-02 through DTA-17

Inputs

Read these before starting this activity. They are produced earlier in the playbook and are authoritative — raise a drift event instead of deviating.

• User Journey (Document, Required) — produced by Define User Journey (#36).
• IA Guidelines (Document, Required) — produced by Define Information Architecture (#37).

Motto: "Code that's easy to prove correct is code that works"

Core Principles

1. Defensive Programming

• Validate all inputs at method boundaries
• Check preconditions explicitly before operations
• Handle edge cases proactively (null, empty, boundary values)
• Fail fast with clear error messages
• Use type hints everywhere for static analysis
• Guard against mutations (prefer immutable data structures)

2. Provable Code

• Single Responsibility: Each method does ONE thing
• Pure functions where possible (no side effects)
• Explicit dependencies: Pass everything needed as parameters
• Deterministic behavior: Same input → Same output
• Small, focused methods: 20-30 lines maximum for public methods
• Clear contracts: Document what's guaranteed vs. what's not

3. Observable Code

• Log at decision points: Why did we take this branch?
• Log state transitions: What changed and why?
• Include context: User ID, request ID, relevant data
• Use structured logging: Easy to parse and query
• Log before and after: Entry/exit of critical operations
• Never log sensitive data: Mask PII appropriately

4. Think-Through Approach

• Start with skeleton: Structure before implementation
• Document thoroughly: Sphinx format with examples
• Pseudocode first: Logic before syntax
• Consider all paths: Success, failure, edge cases
• Design for testability: How will we verify this?

5. Test-First (Red-Green-Refactor)

• Write test before implementation
• Test should fail initially (Red)
• Implement minimum code to pass (Green)
• Refactor with confidence (tests protect you)
• Test all paths: Success, failure, edge cases
• Use descriptive test names: Test name = documentation

6. Clean Code Principles

• Meaningful names: Variables, functions, classes tell their purpose
• Functions do one thing: Single Responsibility
• No magic numbers: Use named constants
• DRY: Don't Repeat Yourself
• Boy Scout Rule: Leave code cleaner than you found it
• Consistent formatting: Follow project style guide

7. SOLID Principles

• Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion

8. Self-Documented Code

• Code explains "what" and "how"
• Comments explain "why"
• Use type hints: They're documentation
• Descriptive variable names: No abbreviations unless obvious
• Examples in docstrings: Show usage
• Codebase as learning materials: Add references for advanced concepts

Workflow

1. Understand Requirements — Read spec, identify edge cases, list assumptions
2. Design (Think-Through) — Skeleton, docstrings, pseudocode, testable units
3. Write Tests (Red) — Happy path, errors, edge cases, boundary conditions
4. Implement (Green) — Minimum code to pass, defensive checks, logging
5. Refactor — Extract helpers, remove duplication, improve naming, SOLID
6. Verify — All tests pass, coverage adequate, logs informative, docs complete

Checklist for Every Method

• Sphinx-formatted docstring with :param:, :return:, :raises:
• Type hints on all parameters and return
• Input validation with clear error messages
• Logging at entry, exit, and decision points
• Tests for success, failure, and edge cases
• Method is < 30 lines (extract helpers if needed)
• No magic numbers (use named constants)
• Follows single responsibility principle
• Self-documenting variable names
• Comments explain "why", not "what"

Remember

• Defensive: Assume inputs are wrong until proven otherwise
• Provable: If you can't test it easily, redesign it
• Observable: Future you will thank you for good logs
• Thoughtful: Pseudocode and docstrings before implementation
• Test-First: Red → Green → Refactor
• Clean: Code is read more than written
• SOLID: Flexible, maintainable, extensible
• Self-Documented: Code that explains itself
