Select focused verification commands for Vellum Assistant changes. Use when deciding what tests, typechecks, lints, or smoke checks to run after editing this repository, especially before commits and pull requests.
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
# Vellum Test Selection ## Core Rule Never run unscoped `bun test` in this repository. The full suite is large and can hang or time out. Choose focused tests based on changed files, then add typechecking when the change affects shared contracts or cross-package behavior. ## Setup Before any Bun command: ```bash export PATH="$HOME/.bun/bin:$PATH" ``` Run commands from the package directory that owns the changed files, usually `assistant`, `gateway`, `cli`, `clients/web`, or `clients/macos`. ## Selection Workflow 1. List changed files and group them by package. 2. For direct implementation/test pairs, run the matching test file. 3. For route, protocol, migration, IPC, provider, or schema changes, run nearby tests plus a package typecheck. 4. For shared TypeScript contracts, run tests for each consumer package that imports the contract. 5. For Swift or macOS client changes, prefer the existing platform-specific test command if one is already used in nearby docs or terminal history. 6. If a command is expected to be long-running, state that before running it. ## Common Commands Assistant focused test: ```bash cd assistant && bun test src/path/to/file.test.ts ``` …

How to install
mdr add vellum-ai/vellum-assistant/vellum-test-selection@sha256:81ea7c76d873db85The line at the top of this page pins the label git:20260702.d65ff55, 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.
