Design review
When to use
Use this skill in one explicitly selected mode:
Prepare mode: assemble an evidence-backed review packet before a review.
Document mode: record an outcome that an authoritative human source says was made.
Do not use it to make a design decision, edit the artifact, or infer approval from a
meeting invite or silence. Not for unscoped aesthetic preference, implementation work,
or publishing requirements and decisions without preview and human confirmation.
Inputs and source discipline
Start with the mode, review scope, timezone, and as-of date/time. Identify the artifact
and exact version, revision, or snapshot; if the version is missing, say so and do not
merge evidence from different iterations.
Gather requirements, user stories, constraints, research, feedback, and prior decisions
from named sources. Record source path or ID, source date, artifact location, and access
date/as-of for each item.
In document mode, identify the authoritative review record and decision authority. Do
not infer participants, owners, intent, or approval from context.
Keep evidence tied to the artifact version reviewed. A later revision is a new subject,
not a correction to the old record.
Method
Confirm prepare or document mode and the exact artifact/version under review.
Build a requirement-to-evidence trace: requirement, artifact location, supporting source
and date, and observed/inferred/unknown status. Include contradictory requirements or
feedback rather than silently choosing one.
Inspect the artifact and evidence read-only. Record strengths, risks, open questions,
and traceable findings with confidence; do not add requirements that are not sourced.
In prepare mode, list options, trade-offs, and questions for human reviewers without
selecting an option. In document mode, record only decisions explicitly stated by the
authoritative source and label them proposed, accepted, or superseded as supported.
Separate recommendations from authorized decisions. A recommendation is not a human
