Define product behavior and acceptance, or reconstruct source-grounded product evidence as an explicitly unaccepted candidate.
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 Specification ## Entry Gate Own current product facts and acceptance, not implementation architecture or visual semantics. Require a named product authority or authorized artifact target; resolve only decisions needed for the requested slice. ## Route Map | Request condition | Read | Result | | --- | --- | --- | | Explicitly reconstruct current product evidence from an existing implementation | [source reconstruction](references/source-reconstruction.md) | Observed candidate and owner decisions; never automatic Ready | | One feature needs behavior, states, and acceptance | [workflow](references/workflow.md) and [template](references/template.md) | Progressive Feature Spec | | Submission failure or uncertain completion affects recovery | [workflow](references/workflow.md#ready-for-an-implementation-slice) | Accepted input, outcome and safe-retry rules, or a scoped Open decision | | New product line/boundary reset is explicit | [workflow](references/workflow.md) | Foundation Spec | | Confirmed changes update a named fact source | [documentation boundaries](references/documentation-boundaries.md) | Bounded artifact update | …

How to install
mdr add idaibin/skills/product-spec@sha256:052025b9f78e23e4The line at the top of this page pins the label git:20261027.a9f9629, 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.
