description

Perform comprehensive software architecture audits to identify improvements for robustness, changeability, and testability. Use when asked to audit, review, or analyze a codebase's architecture, or when asked to suggest structural improvements. Triggers include "architecture audit", "audit the codebase", "review architecture", "architectural analysis", "code structure review", or explicit "/architecture-audit".

Architecture Audit

Analyze a codebase's architecture and provide actionable recommendations to improve robustness, changeability, and testability.

Audit Process

1. Understand scope - Identify target directories/modules
2. Map structure - Explore directory layout and key files
3. Analyze each dimension - Work through checklist systematically
4. Synthesize findings - Identify patterns and root causes
5. Generate report - Deliver prioritized recommendations

Step 1: Scope & Context

Determine audit scope:

• Full codebase or specific modules?
• Any known pain points to focus on?
• Primary language(s) and frameworks?

Use Glob and Grep to understand:

# Directory structure
ls -la, tree (if available)

# Key configuration files
package.json, requirements.txt, go.mod, Cargo.toml, etc.

# Entry points
main.*, index.*, app.*

Step 2: Structure Mapping

Build mental model of the codebase:

• Identify top-level organization (by feature, layer, or domain?)
• Map module boundaries and dependencies
• Note test location and structure
• Identify configuration management approach

Step 3: Systematic Analysis

Work through each dimension. Load references/audit-checklist.md for detailed patterns to assess.

Key dimensions:

1. Code Organization
2. Dependency Management
3. Coupling & Cohesion
4. Testability
5. Error Handling
6. Architectural Patterns

For each dimension, assess and note:

• Current state (what exists)
• Issues found (specific examples with file:line)
• Severity (critical/weak/adequate/strong)

Step 4: Synthesis

Look for patterns across dimensions:

• Root causes behind multiple symptoms
• Quick wins (high impact, low effort)
• Strategic improvements (require planning)

Step 5: Report Generation

Use this report structure:

## Prioritized Recommendations

### Immediate (Quick Wins)
1. [Specific action] - [Why it matters]
2. ...

### Short-term (1-2 sprints)
1. [Specific action] - [Why it matters]
2. ...

### Long-term (Strategic)
1. [Specific action] - [Why it matters]
2. ...

## Summary Table

| Category | Assessment | Priority Issues |
|----------|------------|-----------------|
| Code Organization | ... | ... |

Key Principles

• Be specific - Reference actual files and line numbers
• Prioritize impact - Focus on changes that matter most
• Stay practical - Recommendations should be actionable
• Consider context - Small project != enterprise system
