Architecture-Aware Project Initialization

Overview

Enhanced project initialization that combines:

• Deep online research into current best practices for your project type
• Archetype selection from the 14 paradigms in the archetypes plugin
• Template customization based on chosen architecture
• Decision documentation for future reference

When to Use This Skill

Use this skill when:

• Starting a new project and unsure which architecture fits best
• Want modern, industry-standard architecture choices
• Need justification for architectural decisions
• Want templates customized to your chosen paradigm

Use instead of project-init when architecture is undecided. Use before project-specification to establish architectural foundation.

Required TodoWrite Items

1. arch-init:research-completed - Online research completed
2. arch-init:paradigm-selected - Architecture paradigm chosen
3. arch-init:templates-customized - Templates adapted to paradigm
4. arch-init:decision-recorded - ADR created

5-Step Workflow

Step 1: Gather Project Context

Essential Information (ask user):

1. **Project Type**: What are you building?
   - Web API, CLI tool, data pipeline, desktop app, library, etc.

2. **Domain Complexity**: How complex are the business rules?
   - Simple (CRUD), Moderate (some business logic), Complex (many rules),
     Highly Complex (domain-specific language needed)

3. **Team Context**: Who will build and maintain this?
   - Team size: < 5 | 5-15 | 15-50 | 50+
   - Experience: Junior | Mixed | Senior | Expert
   - Distribution: Co-located | Remote | Distributed

4. **Non-Functional Requirements**:
   - Scalability needs (users, requests/sec, data volume)
   - Performance requirements
   - Security/compliance needs
   - Integration points (external systems, databases, APIs)

5. **Timeline & Constraints**:
   - Time to market: Rapid | Normal | Not urgent
   - Budget constraints
   - Technology constraints (must-use or must-avoid technologies)

Verification: Run the command with --help flag to verify availability.

Step 2: Research Best Practices (arch-init:research-completed)

Online Research Queries (use WebSearch):

For the project type, search for:

# Primary: Architecture patterns for [project type] [year]
WebSearch("[project type] architecture best practices 2026")

# Secondary: Language-specific patterns
WebSearch("[language] [project type] architecture patterns 2026")

# Tertiary: Framework-specific guidance
WebSearch("[framework] architecture patterns [project type]")

Verification: Run the command with --help flag to verify availability.

Research Focus Areas:

1. Current Industry Standards: What are practitioners recommending in 2026?
2. Emerging Patterns: Any new architectural approaches gaining traction?
3. Anti-Patterns: What practices are being actively discouraged?
4. Technology Alignment: Which patterns work best with your chosen stack?
5. Case Studies: Real-world examples of similar projects

Synthesize Findings into:

• Recommended architecture(s) for this project type
• Key trade-offs to consider
• Red flags or anti-patterns to avoid
• Technology-specific considerations

Step 3: Select Architecture Paradigm (arch-init:paradigm-selected)

Option A: Manual Selection Using archetypes Plugin

Invoke the architecture paradigms skill:

**Verification:** Run the command with `--help` flag to verify availability.
Skill(architecture-paradigms)

• Pipeline Architecture
• Microkernel Architecture
• Client-Server Architecture

Option B: Automated Paradigm Matching

Use the decision matrix below to recommend a paradigm based on project context:

**Verification:** Run the command with `--help` flag to verify availability.
┌─────────────────────┬─────────┬─────────┬──────────┬─────────────┐
│ Project Context     │ Simple  │ Moderate│ Complex  │ Highly      │
│                     │ Domain  │ Domain  │ Domain   │ Complex     │

├─────────────────────┼─────────┼─────────┼──────────┼─────────────┤
│ 50+ engineers       │ Micro-  │ Micro-  │ Event-   │ Microkernel │
│                     │ services│ services│ Driven   │ or Space-   │
│                     │         │ + Event │          │ Based       │
└─────────────────────┴─────────┴─────────┴──────────┴─────────────┘

Verification: Run the command with --help flag to verify availability.

Special Cases:

• Real-time/Streaming: Event-Driven + Pipeline
• Bursty/Cloud-Native: Serverless
• Extensible Platform: Microkernel
• Data Processing: Pipeline + Event-Driven
• Legacy Integration: Hexagonal
• High-Throughput Stateful: Space-Based

Step 4: Customize Templates (arch-init:templates-customized)

Template Adaptation Strategy:

1. Load Base Templates for the chosen language (Python/Rust/TypeScript)
2. Apply Architecture-Specific Modifications based on selected paradigm
3. Generate Custom Configuration reflecting architectural choices
4. Create Documentation explaining the architecture

Example Adaptations:

## Context
[Project type, team size, domain complexity, key requirements]

## Decision
[Chosen architecture paradigm]

## Rationale
### Research Findings
[Summarize online research results]

### Key Considerations
- **Team Fit**: [Why this matches team size/experience]
- **Domain Fit**: [Why this matches problem complexity]
- **Technology Fit**: [Why this works with chosen stack]
- **Scalability**: [How this addresses scaling needs]

### Alternatives Considered
1. **[Alternative 1]**: Rejected because [reason]
2. **[Alternative 2]**: Rejected because [reason]

## Consequences
### Positive
- [Benefit 1]
- [Benefit 2]

### Negative
- [Trade-off 1] with mitigation: [strategy]
- [Trade-off 2] with mitigation: [strategy]

## Implementation
- **Templates**: [Which templates were customized]
- **Key Patterns**: [Patterns to follow]
- **Anti-Patterns**: [What to avoid]
- **Resources**: [Links to paradigm skill, examples, etc.]

## References
- [Paradigm skill link]
- [Research sources]
- [Example projects]

Verification: Run the command with --help flag to verify availability.

Output: Complete Initialization Package

After completing this workflow, you'll have:

1. Project Structure: Customized to chosen architecture
2. Configuration: Architecture-appropriate tooling and dependencies
3. Documentation: ADR explaining the architecture choice
4. Guidance: Links to relevant paradigm skill for implementation
5. Examples: Reference projects using similar architecture

Script Integration

Claude Code can invoke the architecture research and template customization scripts:

Architecture Research

# Run architecture researcher for recommendations
uv run python plugins/attune/scripts/architecture_researcher.py \
  --project-type web-api \
  --domain-complexity complex \
  --team-size 5-15 \
  --language python \
  --output-json

Verification: Run python --version to verify Python environment.

The researcher returns a recommendation with:

• Primary paradigm and rationale
• Trade-offs and mitigations
• Alternative paradigms considered
• Confidence level

Template Customization

# Generate architecture-specific directory structure
uv run python plugins/attune/scripts/template_customizer.py \
  --paradigm cqrs-es \
  --language python \
  --project-name my-project \
  --output-dir ./my-project

Verification: Run python --version to verify Python environment.

This creates the paradigm-appropriate structure (e.g., commands/, queries/, events/ for CQRS).

Full Interactive Flow

# Interactive architecture-aware initialization
uv run python plugins/attune/scripts/attune_arch_init.py \
  --name my-project \
  --lang python

# Non-interactive with explicit architecture
uv run python plugins/attune/scripts/attune_arch_init.py \
  --name my-project \
  --lang python \
  --arch hexagonal \
  --accept-recommendation

Verification: Run python --version to verify Python environment.

Using as Library (within Claude Code)

# Import and use programmatically
from architecture_researcher import ArchitectureResearcher, ProjectContext
from template_customizer import TemplateCustomizer

# Create context and get recommendation
context = ProjectContext(
    project_type="web-api",
    domain_complexity="complex",
    team_size="5-15",
    language="python"
)
researcher = ArchitectureResearcher(context)
recommendation = researcher.recommend()

# Apply template customization
customizer = TemplateCustomizer(
    paradigm=recommendation.primary,
    language="python",
    project_name="my-project"
)
customizer.apply_structure(Path("./my-project"))

Verification: Run the command with --help flag to verify availability.

Integration with Existing Commands

This skill enhances /attune:project-init by adding an architecture selection phase:

# Standard initialization (no architecture decision)
/attune:project-init --lang python --name my-project

# Architecture-aware initialization
/attune:brainstorm           # Explore project needs
Skill(architecture-aware-init) # Select architecture based on research
/attune:project-init --arch <paradigm> # Initialize with chosen architecture

Verification: Run python --version to verify Python environment.

Example Session

User: I'm creating a Python web API for a fintech application. Team of 8 developers, complex business rules, need high security and audit trails.

Step 1 - Context: Project type=Web API, Domain=Highly Complex, Team=5-15, Requirements=Security, Auditability

Step 2 - Research:

WebSearch("Python fintech API architecture patterns 2026")
WebSearch("financial services API audit trail architecture")
WebSearch("CQRS Event Sourcing Python examples")

Verification: Run python --version to verify Python environment.

Step 3 - Selection: Research + Decision Matrix → CQRS + Event Sourcing

Step 4 - Templates: Customized structure for CQRS/ES with:

• Command handling module
• Query handling module
• Event store configuration
• Aggregate patterns
• Projection handlers

Step 5 - ADR: Documenting why CQRS/ES for fintech (auditability, complex business rules, regulatory compliance)

Result: Project initialized with architecture-appropriate structure and clear decision rationale.
