## MCP tools (5)

### `read_list` (~62 tokens)

What to read and check before changing these files: the project rules and risks that apply, the checks to run, the tests that reach the code and the files that use it. Call it before editing.

Input parameters:

- `files` (array, required): paths relative to the repository root

### `changed_read_list` (~55 tokens)

The same read list for every file changed on this branch since the base (default origin/main, else main). Call it before finishing, then run the checks it lists.

Input parameters:

- `base` (string): git ref to compare against

### `find_existing` (~96 tokens)

Before writing a new function, helper or module: the functions, classes, files and map entries that may already do it, matched by words (not meaning) against names and paths. Give a few words about what it does, e.g. "payment retry" or "csv export". If one fits, use or extend it instead of writing another.

Input parameters:

- `query` (string, required): a few words about what you are about to write

### `check_map` (~32 tokens)

Whether .readfirst/map.json still covers the code: files in no group, patterns that match nothing, broken rules.

### `audit_repo` (~76 tokens)

The whole repository against .readfirst/map.json, as a report: rules and risks whose files changed a lot since they were written, hot spots that moved, groups never filled in, code no test reaches through imports, and what readfirst could not see. Use it before larger work, or to decide what to add to the map.
