a5c-ai/codebase-sync

• Scan directory structure for project type identification
• Detect language, framework, package manager
• Identify build tools, CI/CD config, test framework
• Map high-level architecture (monorepo, microservices, etc.)

2. Semantic Index Building

Four parallel index domains:

• Code Index: Source files with exports, purposes, dependencies
• Test Index: Test files with cases, fixtures, patterns
• Config Index: Configuration files with parsed rules
• API Index: Public interfaces, types, data models

3. Convention Discovery

• Code style patterns (naming, structure, organization)
• Error handling conventions
• Testing conventions (naming, structure, assertions)
• Git commit message conventions
• Documentation standards
• Language-conditional standards

4. Rule Generation

Convert conventions into enforceable rules:

json
{
  "id": "ts-no-any",
  "category": "coding-standards",
  "description": "Avoid 'any' type; use 'unknown' and narrow",
  "severity": "error",
  "autoFixable": false,
  "language": "typescript"
}

Rule Categories

| Category | Examples | |----------|---------| | core | task-and-workflow, testing, verification | | dev-practices | development-practices, context-management | | tools | research-tools, cli-tools | | coding-standards | Language-specific rules (conditional) |

Output Artifacts

• artifacts/CONVENTIONS.md -- Discovered conventions
• artifacts/SEARCH-INDEX.json -- Semantic search index
• artifacts/RULES.md -- Generated project rules
