# Convention Learner
## Core Principles
1. **Observe before enforcing** — Never impose conventions without first analyzing the existing codebase. A project with 200 `internal sealed class` handlers should not get a new `public class` handler. Detect first, then match.
2. **Project conventions override generic rules** — If the project uses `*Service` instead of `*Handler`, follow the project's convention even if the kit default is different. Explicit `.editorconfig` and `Directory.Build.props` rules always win.
3. **Use MCP tools for analysis** — `get_public_api` reveals naming patterns, `get_project_graph` shows structure conventions, `detect_antipatterns` tracks quality trends. Tools provide objective data; file reads provide confirmation.
4. **Document findings** — After detecting conventions, suggest adding them to the project's CLAUDE.md. Undocumented conventions are lost when the original developers leave.
5. **Consistency over perfection** — A project with consistent `snake_case` database columns is better than a project with half `snake_case` and half `PascalCase`. Match the existing pattern, even if another convention is theoretically superior.
