Use when governing a workspace's control plane, code or not — the `01-TOOLS/` tooling layer, the `02-DOCS/` chaos→knowledge wiki, the root Knowledge map. Audits it, migrates legacy `XX-*` folders, scaffolds provider tooling, sweeps the inbox, eats a file the person hands over ("cómete este fichero", "guárdalo en la documentación": moved into 02-DOCS/raw/ and documented), writes root CLAUDE.md/AGENTS.md. NOT the bootstrap front door (that is `init`, which hands off here).
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
# Harness — the workspace control plane The **harness** is the control plane of a workspace. A workspace need not be code: it can be a company, an ops desk, a legal archive, a personal knowledge vault. Whatever it is, the harness is the durable apparatus that keeps it operable and legible, made of three parts: - **`01-TOOLS/<PROVIDER>/`** — the operational tooling layer. One folder per external provider, co-locating credentials (`.env`) with the scripts that consume them. Each tool ships a working `test_connection` against the real API. - **`02-DOCS/`** — the **Karpathy chaos→knowledge engine**: a domain-agnostic LLM wiki (`inbox/`, `raw/`, `raw/worklog/`, `wiki/` with its `index.md` / `log.md` / `gaps.md` / `scores.json` and `.base` views), embedded in this skill — no external sub-skill required. Two on-ramps feed it. **Ingest**: the user drops any file in any format into `inbox/`, and the Auto-Ingest Sweep extracts, classifies, cross-links and compiles it — then goes for a walk, discovering un-ingested documents anywhere in the workspace, bounded by `.rscignore` (baseline: `references/ingest-ignore-defaults.md`) and de-duplicated through the `wiki/.ingested.json` …

How to install
mdr add ericrisco/rsc-harness/harness@sha256:440730e1629a7158The line at the top of this page pins the label git:20261019.37d4c1f, 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.
