Maker/checker loop for shipping a verified code change: triage → isolated worktree → maker implements → cross-model edit-locked checker emits a {verdict} envelope → verify-gate → durable human hold → integrate. Use when the user wants a change made AND independently verified before it lands, asks to "run the maker/checker loop", "review with a cross-model checker", gate a merge, or run a long iterative edit→check loop safely. Also exposes a read-only reasoning one-shot for…
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
# secondmate — maker/checker loop hardening
**Setup:** run `/secondmate-doctor` once — it detects and installs the harness + companions (herdr, ponytail,
adhd) and reports what's missing; the human only approves each action. The `/loop-task` command ships
with this plugin. Cross-model checking
additionally needs a second model family + credentials, which only the human can supply.
Scripts live in `${CLAUDE_PLUGIN_ROOT}/bin/` (a `${CLAUDE_PLUGIN_ROOT}/bin/reason.sh` etc.).
If `$CLAUDE_PLUGIN_ROOT` is unset in your shell, resolve it once: it is this plugin's install dir
(under `~/.claude/plugins/marketplaces/secondmate` or your skills dir). All scripts carry `--selfcheck`/
`selfcheck` and are harness-neutral; the checker/reasoning harness + model are set by env
(see the Config section of the plugin README). You (the supervisor) invoke these — the user does not.
## Roles
- **Top-level supervisor** (you, when a human is directly present) — recognizes the trigger test, dispatches
a fresh sub-agent-supervisor (see "Dispatch — the standard path" below), watches for progress/staleness

How to install
mdr add eshwarvijay/secondmate/secondmate@sha256:03ef9c7a94933167The line at the top of this page pins the label git:20261022.716ebc3, 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.
