Conciseness

The body is mostly efficient, instruction-first writing, but includes clear redundancy: the read-only constraint is stated three times ("strictly read-only -- it never modifies files", "MUST NOT use Write or Edit", and the Constraints section), and Steps 2/3 restate detection rules and cross-plugin hint strings (e.g., "Spark exploration: active — run `/arn-spark-help` for details.") verbatim from pipeline-map.md even while instructing the reader to load that file. This is anchor 3 ("could be tightened") rather than anchor 4 ("minor instances"), because the duplication spans multiple sections.

Actionability

The guidance is fully executable for an instruction-only skill: exact artifact paths and JSON fields ("PROGRESS_TRACKER.json with overallStatus = \"completed\"", "reports/IMPLEMENTATION_REPORT_*.json", "TASKS.md with parseable task entries", "INTRODUCTION.md"), exact glob patterns (SWIFT_*, PLAN_PREVIEW_*.md, FEATURE_*.md), exact output strings, and per-error-case commands. This matches anchor 5's copy-paste-ready coverage of common cases.

Workflow Clarity

Steps 0-4 are clearly sequenced with a thorough six-case Error Handling section functioning as recovery paths, matching anchor 4's clear sequence with most checkpoints present. It is not anchor 5 because of internal inconsistencies: SKILL.md Step 1 says render the core diagram with all stages unmarked when ## Arness is missing, while pipeline-map.md's annotation instructions say to skip the diagram; Step 0 references the ## Arness section "loaded in Step 1" (a forward dependency); and the inline per-project detection list omits ship/simplify-done stages present in the reference's authoritative table.

Progressive Disclosure

The body points to a real, verified, one-level-deep reference (${CLAUDE_PLUGIN_ROOT}/skills/arn-code-help/references/pipeline-map.md, cited in Steps 2, 3, and 4) with clear signaling, matching anchor 4's good structure. It falls short of anchor 5's "content appropriately split" because the detection rules, next-step suggestion strings, and cross-plugin hints are duplicated inline in SKILL.md instead of living solely in the reference.

Specificity

The description names the domain ("Arness workflow pipeline") and 1-2 outcome-level actions ("see their current position", "get guidance on the next step"), which matches anchor 3. It does not list several concrete actions (ASCII diagram rendering, next-command suggestion, cross-plugin hints), so it falls short of anchor 4; it is well above anchor 2's minimal/generic action level.

Completeness

Both questions are explicitly answered: "This skill should be used when the user says ... or wants to see their current position in the Arness workflow pipeline and get guidance on the next step" provides an explicit use-when clause with concrete trigger phrases plus a clear what-clause. This matches anchor 5; anchor 4's deficit ('when' could be more explicit) does not apply since the when-guidance is maximally explicit.

Trigger Term Quality

Comprehensive natural trigger coverage with synonyms and command-name variants: "arness code help", "arn-code-help", "arness code status", "show pipeline", "pipeline status", "show workflow", "what step am I on" — phrases a user would naturally say. This matches anchor 5's comprehensive synonym coverage; only marginal variants like "workflow status" are absent, so it is not the anchor-4 case of clearly missing natural terms.

Distinctiveness Conflict Risk

Arness-specific terms ("arness code help", "arness code status", "pipeline status") are distinctive, but the generic phrases "where am I" and "what's next" would equally trigger sibling skills such as arn-spark-help and arn-infra-help, which plausibly describe themselves the same way. This is anchor 3 ("somewhat specific but could still overlap with similar skills") rather than anchor 4, whose minor-overlap framing understates the near-identical generic triggers across the plugin family.
