Conciseness

The body never explains concepts Claude already knows and is dense with operational specifics, but core rules are repeated 3-5 times across sections ('unresolved comment blocks the accept' appears in the tool table, Recipe 1, Recipe 6, and Guardrails; 'render both images' and 'trust the judge's regression verdict' each appear twice), and several tool-table cells run 50-150 words where one line would carry the essential. Anchor 3 ('mostly efficient but could be tightened') fits better than 4 because this duplication is more than minor.

Actionability

Fully executable throughout: exact MCP setup commands ('claude mcp add --transport http uiverify https://uiverify.ai/api/mcp --header ...'), JSON config for Cursor, concrete tool invocations with args ('accept_build { prNumber: 123 }', 'render_diff_image which: baseline AND candidate'), a download command ('curl -L "$url" -o before.png'), and worked example output shapes for the PR comment. Matches the anchor 'copy-paste ready commands; specific examples cover the common cases'.

Workflow Clarity

Each recipe is a clear sequence with explicit validation checkpoints: confirm 'bucket ⚠️ empty' before bulk accept, 'list_comments it and honor it before review_diff / accept_build', and 'Resolve before you accept'. Feedback loops are explicit (accept refused while unresolved comments exist — the error names the stories — then read/address/resolve/retry), and the Guardrails section acts as a checklist. The batch operation (accept_build) has validation, so the destructive/batch cap does not apply.

Progressive Disclosure

Sections are clearly organized (MCP setup, tool table, six recipes, passed-build, guardrails), but the ~600-word tool table is effectively an API reference inlined in a 155-line SKILL.md, and no bundle files exist to offload it. Anchor 3 ('content that should be separate is inline') fits; not 4 because the inlined tool reference is a real organization gap, not a minor one.

Specificity

The description lists several concrete actions ('bucket a build's changed stories into real regressions vs cosmetic reflow vs rendering noise, summarize the real regressions for a PR comment, and accept baselines in bulk'), a base 4 with minor gaps (PR before/after images, whole-PR changeset, and comment workflows uncovered). The when-clause 'when... you want the agent to review, summarize, or accept from the terminal' is second person, which the judging guidelines penalize by reducing specificity by 1, landing at 3.

Completeness

Explicitly answers both questions: what ('bucket a build's changed stories into real regressions vs cosmetic reflow vs rendering noise, summarize... for a PR comment, and accept baselines in bulk') and when ('Use after a UI Verify build reports changes...'), with concrete trigger phrases appended. Matches the anchor-5 example structure exactly.

Trigger Term Quality

Good natural-phrase coverage: 'Triggers - "triage this build", "summarize the visual regressions", "accept all the new baselines"' are phrases a user would actually say, plus 'visual regressions' and 'accept baselines' in the body of the description. Missing a few common variations ('visual diff review', 'screenshot regressions'), so it sits between anchors 4 and 5 but closer to 4.

Distinctiveness Conflict Risk

A clear niche with minimal conflict risk: 'UI Verify build', 'UI Verify MCP', and 'uv_proj_... API key' name a specific product and workflow, and the trigger phrases ('triage this build', 'accept all the new baselines') are specific to this tool, so no other skill would plausibly claim them.
