Convention discovery and rule generation from codebase analysis. Scans project structure, builds search indexes, identifies patterns, and generates enforceable rules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
- 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 |

How to install
mdr add a5c-ai/babysitter/codebase-sync@sha256:ebd1b7cfdb89ce0fThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
