# packages/machine-ops

`@code-yeongyu/senpi-machine-ops`: the engine-free operation layer shared by senpi's built-in tools

(`packages/coding-agent/src/core/tools/machine.ts`) and remote machine executors.

## RULES

- Import only `node:*`, `bun:*`, `@earendil-works/pi-pty` and this package's own files. `test/dependency-boundary.test.ts`

enforces it; never import from `packages/agent` or `packages/coding-agent`.

- No concurrency cap anywhere. Ordering exists only where semantics need it: one canonical path's mutations

(`files/mutation-queue.ts`) and one handle's input.

- Filesystem and spawn errors pass through unchanged so the tools keep their exact error text; errors the layer

raises itself are `MachineOpError` with a code.

- Every behaviour change needs a case in `test/conformance/`, the suite other consumers run.

+ - Disk state and the `SENPI_MACHINE_SCOPE` child variable exist only when the caller passes a `stateDir`; senpi's tool

+ path passes none and must stay free of agent-dir writes.

## VALIDATION

- `bun run --cwd packages/machine-ops test`

- Root `bun run check`
