Conciseness

The step content is lean and never explains concepts Claude already knows, but several padded meta sections exist: the "Core Identity" quote, the "Explicit User Instruction" preamble, a Scope Boundaries list that restates the Execution Protocol, and four near-identical "Execute Skill ... before planning or applying adjustment edits" lines in Step 5. Matches anchor 3 ("mostly efficient but ... could be tightened"); not 2 because the verbosity is concentrated in a few removable sections rather than pervasive padding.

Actionability

Guidance is largely executable for an instruction-only skill: an exact subagent invocation with per-parameter spec (`subagent_type: "dev-workflows-frontend:quality-fixer-frontend"`, `direct_scope`, `governing_sources`, `observable_verification`), an exact escalation message for the 0-files case, exact commit trailers (`Verification-Limitation: <reason>` / `Verification-Affected: <affected check or command>`), and a concrete output template. Not 5 because Step 5's verification mechanics ("compare rendering, interaction or tokens") and Step 2's "smallest sufficient repository evidence" remain abstract and defer to external skills.

Workflow Clarity

Steps 1-7 are explicitly ordered with an overview diagram, hard gates ("Stop at every `[Stop: ...]` marker", the Step 3 escalation stop, the Step 4 `[STOP]` for user confirmation), a quality feedback loop (`stub_detected` returns to Step 5), retained-limitation retry logic after commit, and a Completion Criteria checklist. Matches anchor 5 (clear sequence, explicit validation steps, feedback loops, checklists).

Progressive Disclosure

No bundle files exist; all content lives in one well-sectioned file with clear headers (Execution Pattern, Workflow Overview, Steps 1-7, Completion Criteria, Output Example) and clearly signaled one-level pointers to other skills ("Execute Skill: ai-development-guide and read its `references/frontend.md`"). Matches anchor 4; not 5 because at ~145 lines (above the under-50-line exception) content such as the quality-fixer-frontend invocation spec or the Step 7 continuation/trailer rules could be split into a reference file.

Specificity

"Adjust an already-implemented UI" and "verification against the design source" name the domain plus two concrete actions, but the edit-refine loop, quality checks, and commit that the body covers are absent. Matches anchor 3 ("names domain and 1-2 concrete actions, but not comprehensive"); not 4 because it does not list several specific actions.

Completeness

The "what" is clear ("Adjust an already-implemented UI ... with verification against the design source"), but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not 4 because the "when" is entirely absent rather than present but imprecise.

Trigger Term Quality

"Adjust" and "UI" are terms a user might naturally say, but common phrasings like "tweak", "modify", "restyle", "fix", or "frontend" are missing. Matches anchor 3 ("some relevant keywords but missing common variations or synonyms"); not 4 because coverage is thin rather than missing only a few natural terms.

Distinctiveness Conflict Risk

"already-implemented" and "verification against the design source" carve a niche clearly separate from a from-scratch frontend design skill, leaving only minor overlap risk with closely related frontend/design skills. Not 3 because these qualifiers make it more specific than "works with UI"; not 5 because without trigger phrases, general UI-change requests could still match sibling skills.
