# Test, lint, commit > Run tests, lint, and typecheck through the agent with auto-detected toolchains, then commit with a clean conventional-commit message after pre-commit checks ## Run your tests ``` > run tests ``` The agent auto-detects your toolchain (Bun, npm, cargo, go, pytest, gradle, and 20+ others) and runs the right command. Target a specific test: ``` > run only the auth tests ``` ## Lint and auto-fix ``` > lint and fix everything ``` Runs your linter (biome, eslint, oxlint, ruff, clippy, golangci-lint - auto-detected) with the fix flag where supported. ## Typecheck ``` > typecheck ``` Runs `tsc --noEmit`, `mypy`, `pyright`, `cargo check`, `dart analyze`, etc. ## Commit Press `Ctrl+G`, then `c`. Or: ``` > commit my changes ``` Empryo: 1. Runs lint + typecheck (blocks if either fails). 2. Writes a conventional-commit message based on your diff. 3. Shows you the message and the diff. 4. Commits after you confirm. To skip the pre-commit checks, commit via shell outside Empryo. ## Co-author trailers Add your LLM as a co-author: ``` /git co-author ``` Toggles between on (adds `Co-Authored-By: `) and off. Saved per-scope. ## The `project` tool Under the hood, all of the above use the `project` tool. If you want to run it directly: | Ask | Runs | |-----|------| | "run tests" | `project(action: "test")` | | "run the auth tests" | `project(action: "test", file: "auth")` | | "build" | `project(action: "build")` | | "lint and fix" | `project(action: "lint", fix: true)` | | "typecheck" | `project(action: "typecheck")` | | "what packages are in this monorepo?" | `project(action: "list")` | See [project tool](/docs/tools/project) for the full list of supported ecosystems.
