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

# Brand and style

Agent Harness is direct, inspectable and calm. Documentation leads with what a developer can do,
then states current limits without promotional inflation. The product has no required graphical
surface for v1; this contract governs documentation, terminal examples and future explanatory UI.

# Colors

Status meaning must not depend on color. Any future surface uses named semantic states—supported,
preview, planned, unsupported, unknown and failed—and renders their text labels visibly.

# Typography

Use the host system's readable sans-serif for prose and monospace for commands, paths and structured
output. Avoid decorative display typography in operational surfaces.

# Layout and spacing

Put the outcome and next safe action first. Keep commands copyable and keep caveats adjacent to the
claim they limit. Dense evidence belongs behind a link, not above the first experiment.

# Components

- **Status line:** literal state plus subject and evidence scope.
- **Command block:** complete executable command with no hidden prerequisite.
- **Evidence callout:** observed behavior, exact surface and limitations.

# Dos and don'ts
…

How to install

The exact contents, by fingerprint
mdr add jakeselby/model-citizen/_bmad-output/planning-artifacts/ux-designs/ux-agent-harness-2026-09-19/DESIGN.md@sha256:fd177fd2ea63b8ff

The line at the top of this page pins the label git:20260923.47f11bb, 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.
