Use when a product direction, feature, workflow, experiment, launch, feedback signal, automation, or scale decision needs judgment before execution or the next iteration.

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

# Product Design Harness

Decide whether a product direction should continue, be verified, or be
reframed anywhere in the product loop.

Execution includes design, implementation, prototype, launch, growth,
automation, or investment.

## Start

Load in this order:

1. `resources/schemas/session-config.schema.json`: set `working_language`; keep
   `canonical_identifiers` in English.
2. `resources/knowledge/ontology.json`: use the canonical UX3 knowledge kernel and its
   approved Flow definitions.
3. `resources/knowledge/rules.json`: load required rules plus only triggered conditional
   rules.
4. `resources/prompts/start-review.md`.

Then fill `resources/templates/product-brief.md`, select the smallest responsible mode,
and return `resources/schemas/review-result.schema.json`.

Validate every review result with `resources/scripts/check_review.py`. JSON Schema checks
shape and conditional fields; `check_review.py` is the canonical validator for
the worst-verdict, weakest-flow, and headline-tier semantic checks.

## Modes

| Mode | Use when |
|---|---|
| Quick Gate | Small, reversible, low-risk change. |
| Standard Gate | New feature, workflow, or experiment. |

How to install

The exact contents, by fingerprint
mdr add cis2042/product-design-harness/product-design-harness@sha256:ebdb52ec57481aef

The line at the top of this page pins the label git:20260725.fbab313, 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.
