Claude.md

It helps to nudge claude a little to use lsp over grep, otherwise it defaults to what it knows. Putting the following into claude.md is what I do:

## Code Intelligence

Prefer LSP over Grep/Glob/Read for code navigation:
- `goToDefinition` / `goToImplementation` to jump to source
- `findReferences` to see all usages across the codebase
- `workspaceSymbol` to find where something is defined
- `documentSymbol` to list all symbols in a file
- `incomingCalls` / `outgoingCalls` for call hierarchy

Before renaming or changing a function signature, use
`findReferences` to find all call sites first.

Use Grep/Glob for text/pattern searches (comments, strings,
config values, Datalog rule names) where LSP doesn't help.

Tip: `goToDefinition` may need multiple hops for aliased
namespaces (e.g., `auth-service/foo` → alias → actual fn).
