Work on any of the operator's projects through the cromford fleet — load a project into the fleet (load-project.sh), plan locally and hand the plan off as ai-build GitHub Issues the remote pipeline executes, and check/steer remote build status. Use when asked to "load a project into the harness", "hand this plan to the harness", "have the harness build this", "harness status", or to onboard a repo for remote autonomous builds.

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 — remote builds through the cromford fleet

The fleet (repo `~/cromford`, private `example-org/cromford`) watches
project boards and runs the full pipeline remotely: PLAN (acceptance tests + QA
screens) → red/green EXECUTE → semgrep → adversarial REVIEW → PR → preview QA →
merge lanes → deploy-verify, with model fallbacks, Fly builder lanes, cost-per-PR
attribution, and a watchdog. Small projects share one box (`box-small`);
their "board" is **GitHub Issues labeled `ai-build`** on the project repo.

Three verbs. Pick from the user's intent:

## 1. load — onboard a project into the fleet

```bash
cd ~/cromford && git pull --ff-only
bin/load-project.sh <owner/repo>              # e.g. example-org/project-11
#  --prod <url>        prod base URL (healthchecks + comment links)
#  --box <host>        default box-small
#  --context <file>    extra prompt context (mission, sharp edges)
#  --prefix <KEY>      ticket key prefix (default: initials, project-11 → RA)
#  --require-readiness <n>  refuse to enrol below this level (default 0 = off;
#                      n is 0..max_level from catalog/readiness-levels.json)

How to install

The exact contents, by fingerprint

mdr add cromford-ai/cromford/harness@sha256:0d92a88dfcdc7c38

The line at the top of this page pins the label git:20261106.49a4c76, 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.
