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

# SandBase Harness Agent Instructions

This file is the agent-facing shortcut and role index. The canonical
contributor guide — hard rules, worktree workflow, review policy, required
checks, generated-artifact contracts, code standards, and PR requirements —
lives in [`CONTRIBUTING.md`](./CONTRIBUTING.md).

Read `CONTRIBUTING.md` before touching code. Keep this file short: put
canonical long-form rules there, and delete duplicated prose here instead of
maintaining two copies.

## Project identity

SandBase Harness (`managed-agents`) is a local-first, self-hosted runtime for
AI agents. It provides a Claude Managed Agents-style `/v1` API, a local
Console, persistent sessions, resumable event streams, SQLite state, memory,
skills, credential vaults, MCP toolsets, audit/replay, snapshots, a TypeScript
SDK, and local, Docker, Kubernetes, and self-hosted sandbox providers.

This is an independent SandBase open-source project. It is not an official
Anthropic, DeepSeek, or DSH implementation. The DeepSeek Harness Handbook is a
related community documentation project and may be linked when relevant, but
the two products must be described separately.

How to install

The exact contents, by fingerprint
mdr add sandbaseai/sandbase-harness/AGENTS.md@sha256:aec6d56458a1dfbd

The line at the top of this page pins the label git:20260928.6a6b079, 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.
