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
# src/harness Optional Node-side harness over the core agent loop: durable sessions, lane operation state machine, compaction, skills/prompt templates, built-in tools, and schema-first telemetry. Public entry `AgentHarness` (`agent-harness.ts`, built by `createAgentHarness` from `runtime/harness.ts`), exported via `src/node.ts`. Earned its own file: ~80 files, distinct domain from the browser-safe core (file count, export surface, 23+ `AgentHarness` references in coding-agent). ## WHERE TO LOOK | Task | File | |---|---| | Public interfaces and re-exports | `agent-harness.ts` (`AgentHarness`, `AgentLane`, `LaneSnapshot`, `SuspendedRun`) | | Harness/lane implementations, restore on open | `runtime/harness.ts` (`Harness`, `createAgentHarness`), `runtime/lane.ts` (`Lane`), `runtime/restore.ts` (`restoreSession`, `restoreLaneState`) | | Operation drive loop and its phases | `runtime/drive.ts` (`driveOperation`), `runtime/drive/` (`checkpoint.ts`, `generation.ts`, `tools.ts`, `boundary.ts`, `deferred.ts`, `structural.ts`, `recovery.ts`, `retry.ts`, `terminal.ts`) | | Lane snapshot reduction from events | `runtime/reducer.ts` (`reduceLaneSnapshot`) | …

How to install
mdr add code-yeongyu/senpi/packages/agent/src/harness/AGENTS.md@sha256:6fa7db66b15f7472The line at the top of this page pins the label git:20260912.2086f4d, 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.
