Install the harness-kit pipeline into the current project. Copies agents, slash commands, skills, and hooks into the project's .claude/, plus AGENTS.md and CLAUDE.md at the repo root. Run after adding the harness-kit plugin from the marketplace.
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
Install harness-kit into the user's project. Plugin ships full harness; this skill lays it down via bundled installer.
## What it writes
Installer copies into the **target project** (`${CLAUDE_PROJECT_DIR}`):
- `.claude/agents/`, product-manager + staff-software-engineer (sensors, evals, guides, skills)
- `.claude/commands/`, `/product-manager:*`, `/sse:*`, `/pipeline:*`, `/context:*`
- `.claude/runtime/`, per-agent hooks + scripts (outputs/ stay target-side state)
- `.claude/hooks/` + `.claude/scripts/`, pipeline tracking, token accounting, opt-in pipeline status bar
- `.claude/shared/`, cross-agent guides
- `.claude/conventions/`, scaffold for project overrides
- `.claude/settings.json`, wires hooks (existing one backed up first). No statusLine: user keeps own global one. Pipeline bar only with `HK_STATUSLINE=1`
- `AGENTS.md` at repo root; `CLAUDE.md` if absent
This modifies files in the user's repo. Tell user what runs before running. Existing `.claude/settings.json` backed up to `.claude/settings.json.bak.<stamp>`.
## Run
Requires `git` + `python3` (installer checks, exits if missing).
```bash
bash "${CLAUDE_PLUGIN_ROOT}/setup/install.sh" "${CLAUDE_PROJECT_DIR}"
```

How to install
mdr add pierry/harness-kit/install@sha256:b8616d8f527f0222The line at the top of this page pins the label git:20261005.0119af1, 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.
