Conciseness

The body uses a telegraphic, directive style ("Skeleton generation → delegate to acceptance-test-generator", exact field mappings) that assumes Claude's competence and contains no concept explanations or padding. Minor tightening is possible — e.g. the dense Step 1 discovery paragraph and repeated "Apply Specialist Result Acceptance" phrasing — so it is not fully lean (not 5) but is clearly efficient (not 3).

Actionability

Concrete, near-copy-paste Agent invocation specs are given: exact subagent_type values ("dev-workflows-fullstack:acceptance-test-generator"), per-field prompt mappings, expected outputs (generatedFiles, testsAdded, mutationEvidence), and a commit message format ("test: add [layer] integration tests for [feature name]"). The gap: execution hinges on external guide concepts (HC-06, Specialist Result Acceptance, Commit Boundary Check) that are named but not summarized here (not 5), though the guidance is far more executable than high-level hints (not 3).

Workflow Clarity

Steps 1-7 are explicitly ordered with per-step response gates ("At least one changed integration/E2E test file ... → Proceed to Step 4"), status-based routing, and explicit feedback loops: needs_revision returns to Step 4 via the Review Resolution Gate, stub_detected returns to Step 3, and Step 7 defines a retry loop for retained verification limitations. Validation checkpoints are explicit throughout, matching the top anchor rather than the implicit-checkpoint anchor below it.

Progressive Disclosure

The single file is well organized with clear section headers and per-step subsections, and the one file reference is clearly signaled and one level deep ("read references/review-resolution.md from the loaded subagents-orchestration-guide skill"); no bundle files exist for this skill, so nothing is misplaced. At ~120 lines of dense inline gate logic, some gate detail could arguably live in a reference file, keeping it below the ideal split of anchor 5 (not 5) while structure is clearly good (not 3).

Specificity

"Add integration/E2E tests to existing codebase using Design Docs" names the domain and one concrete action with its input artifacts, but lists no further capabilities (no mention of skeleton generation, review, or commit). It is more than a bare domain label (not 2) but does not list several specific actions (not 4).

Completeness

The "what" is clear ("Add integration/E2E tests to existing codebase using Design Docs") but there is no "Use when..." clause or equivalent explicit trigger guidance; the "when" is only weakly implied by the Design Doc prerequisite. Per the judging guideline, a missing trigger clause caps completeness at 3.

Trigger Term Quality

"integration", "E2E", and "tests" are terms a user would naturally say when needing this skill, giving good keyword coverage. Common variations like "end-to-end" spelled out, "test coverage", or "acceptance tests" are missing, so it falls short of comprehensive (not 5) but is well above a single generic keyword (not 3).

Distinctiveness Conflict Risk

"using Design Docs" and "existing codebase" carve out a distinct niche that separates it from generic test-writing skills, leaving only minor overlap risk with closely related test recipes. It lacks the fully distinct trigger set of anchor 5 (not 5) but is clearly more specific than anchor 3 (not 3).
