Conciseness

The body is efficient — commands are presented with one-line expected results and no explanation of concepts Claude already knows. It falls short of anchor 5 due to redundancy: the unexpected-differences checklist appears nearly verbatim in both workflow step 3 ("verify identical conditions (URL, viewport, seed data, build mode)") and the Troubleshooting section, and the four-part WHY/BAD/GOOD/Consequence anti-pattern template adds padding. It is clearly above anchor 3, which would require substantial unnecessary explanation.

Actionability

Every command is copy-paste ready with full arguments — "./skills/ui-debug-workflow/scripts/capture-evidence.sh baseline http://localhost:3000 ./baseline", "npx playwright install chromium", "full-debug-session.sh main fix/my-branch http://localhost:3000 'npm run build' 'npm start'" — and each includes an expected result. This matches the anchor for fully executable guidance covering the common cases; there are no pseudocode or missing-detail gaps.

Workflow Clarity

The Deterministic Workflow gives a clear 5-step sequence with an explicit validation checkpoint and feedback loop in step 3 ("verify identical conditions ... re-capture both runs if needed before concluding"), reinforced by a Troubleshooting section with recovery steps for each failure mode. This matches the anchor for explicit validation with error-recovery loops; anchor 4 would imply missing checkpoints, which are present.

Progressive Disclosure

SKILL.md is a well-organized overview with clearly signaled one-level-deep references ("references/debugging-checklist.md", "references/browser-devtools-guide.md", "references/evidence-templates.md" — all verified to exist with real content). However, the bundle contains roughly a dozen additional reference files (e.g. "dom-snapshots-evidence-collection.md", "playwright-testing-browser-automation.md", "logs-evidence-collection.md") that are not referenced or navigable from SKILL.md, an organization gap beyond the "minor" allowance of anchor 5.

Specificity

The description lists multiple concrete actions — "validating visual regressions, reproducing frontend bugs, comparing baseline vs changed behavior, collecting screenshots/DOM/logs, or producing stakeholder-ready UI debug reports" — covering the full debug cycle from reproduction to reporting. It matches the anchor for comprehensive coverage rather than anchor 4, which reserves room for minor gaps in action coverage.

Completeness

It explicitly answers both what ("Debug UI changes with a repeatable evidence-first workflow") and when ("Use when validating visual regressions, reproducing frontend bugs, ...") with concrete trigger phrases, matching the anchor-5 example pattern exactly. Not anchor 4, since the 'when' clause is fully explicit rather than merely serviceable.

Trigger Term Quality

"Keywords: ui bug, visual regression, browser devtools, playwright, screenshot evidence, dom snapshot, frontend debugging" provides good natural-phrase coverage a user would plausibly say. It falls short of anchor 5 because common variations like "screenshot diff", "ui testing", or "frontend issue" are missing, though it is clearly above anchor 3's "missing common variations".

Distinctiveness Conflict Risk

The niche — evidence-first UI debugging with baseline/changed comparison — is distinct and the triggers (visual regression, screenshot evidence, DOM snapshot) are specific to it. The "playwright" keyword creates only minimal overlap with generic browser-automation skills, keeping it at anchor 5 rather than requiring the anchor-4 caveat.
