Codebase sync

Skill a5c-ai/babysitter/library/methodologies/pilot-shell/skills/codebase-sync

Convention discovery and rule generation from codebase analysis. Scans project structure, builds search indexes, identifies patterns, and generates enforceable rules.From its SKILL.md

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:

{
  "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
