Ignoring files

Ignored files are left out of the changed-file list and the diff Otto reviews. Otto can still read them for context, for example to check how a generated type is used.

otto.yml

version: 1
reviews:
  ignore:
    - '**/*.snap'
    - 'fixtures/**'
    - 'src/generated/**'

Ignored files also:

Don’t count toward the 100-file limit for automatic reviews, so ignoring generated code can bring a large PR back under it.
Don’t count when Otto picks the review depth or decides which path instructions apply.

Globs match the full path from the repository root. Use **/ to match at any depth. See Globs.

Default ignores

Once a repository has an otto.yml, Otto also ignores this built-in list unless you set default_ignores: false. Each pattern matches at any depth.

Group	Patterns
Lockfiles	`package-lock.json`, `npm-shrinkwrap.json`, `yarn.lock`, `pnpm-lock.yaml`, `bun.lock`, `bun.lockb`, `Cargo.lock`, `Gemfile.lock`, `composer.lock`, `poetry.lock`, `Pipfile.lock`, `uv.lock`, `go.sum`, `packages.lock.json`, `Podfile.lock`, `pubspec.lock`, `mix.lock`, `flake.lock`
Build output	`dist/`, `build/`
Minified files	`.min.js`, `.min.css`
Source maps	`*.map`
Vendored code	`vendor/`, `node_modules/`, `third_party/`, `third-party/`
Generated code	`__generated__/`, `.generated.`, `.pb.go`, `_pb2.py`, `*_pb2_grpc.py`

Without an otto.yml, Otto ignores nothing. Committing an otto.yml with only version: 1 turns on the default ignores.

Turning the defaults off

Set default_ignores: false if your repository keeps source code in one of these places, for example a build/ directory of build scripts or a Go vendor/ directory you want reviewed:

otto.yml

version: 1
reviews:
  default_ignores: false
  ignore:
    - '**/pnpm-lock.yaml'
    - '**/dist/**'

The defaults are all or nothing: to keep some of them, turn them off and list the ones you want in ignore.
