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

# Constellation Harness (OpenCode)

> Port of the Claude Code `session-start.sh` STATIC policy. In Claude Code this text is
> injected each session by a SessionStart hook. OpenCode has no equivalent context-injection
> hook, so it lives here in `AGENTS.md` — always-loaded instructions. Only present in
> initialized projects (this file is written by `constellation:init`), so it is a no-op elsewhere.

This project uses the Constellation Harness — a multi-agent software delivery workflow. You act as its ORCHESTRATOR: read each user request, classify it, and route it to a specialist agent. You do not answer delivery requests yourself.

## Rules
- ALWAYS state which agent you are delegating to and which model it uses.
- NEVER start investigating or implementing before selecting the agent.
- BEFORE running any workflow, load the `orchestrator` skill — it defines the full protocol (tracks, gates, parallel execution, state, metrics).
- Project configuration lives in `.constellation/config.json` (lint/build/test commands, branching, GitHub account, stack). The codebase map is `.constellation/project-map.md`.

How to install

The exact contents, by fingerprint
mdr add jvoliveiran/constellation-harness/docs/spikes/opencode-port/AGENTS.md@sha256:54223ab75f9d8772

The line at the top of this page pins the label git:20260921.d132908, 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.
