Conciseness

The body is lean and directive with zero padding — every line is an instruction or a boundary, and it fully assumes Claude's competence (e.g., 'Detect repository metadata once'). This matches anchor 5 (lean, efficient, every token earns its place); nothing could be cut without losing guidance.

Actionability

Steps are specific directives and include one exact command ('ask --chain --artifact-reply'), but key execution details are missing: 'Run focused verification when possible' names no verification method, and the required evidence format for the returned 'verification evidence' is unspecified. This is anchor 3 (some concrete guidance but incomplete); anchor 4 would need the verification and submission mechanics spelled out.

Workflow Clarity

The six-step sequence is clear with an explicit rework loop and stop conditions ('After Reviewer pass, perform no more file/tool mutation and immediately return...'). It is not anchor 5 because validation is conditional ('when possible') rather than an explicit checkpoint with an error-recovery path; it is above anchor 3 because sequencing, rework, and termination are all explicit.

Progressive Disclosure

The skill is under 50 lines with no external references needed, and its content is organized into clear 'Workflow' and 'Boundaries' sections. Per the simple-skill guidance, well-organized sections alone warrant anchor 5; there are no bundle files to evaluate and no buried or nested references.

Specificity

The description names the domain ('scoped implementation or investigation item') and two concrete actions ('Execute', 'return evidence'), but coverage is thin and 'without changing workflow authority' is abstract. It matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than anchor 4, which expects a fuller list of specific actions.

Completeness

The 'what' is explicit (execute one scoped item, return evidence), but there is no 'Use when...' clause or equivalent trigger guidance, capping completeness at 3 per the judging guidelines. It is not a 2 because the 'what' half is clearly stated.

Trigger Term Quality

The only candidate keywords are orchestration jargon ('workflow authority', 'evidence', 'scoped item') rather than natural phrases a user would say when needing this skill. It sits at anchor 2 (one or two generic keywords, missing the natural phrases users say); anchor 3 would require relevant keywords like 'task', 'work item', or 'ticket' that a requester might actually use.

Distinctiveness Conflict Risk

'Without changing workflow authority' gives it a recognizable niche, but 'implementation or investigation item' is broad enough to overlap with general coding and research skills. Anchor 3 (somewhat specific but could still overlap with similar skills) fits; anchor 4 would require a tighter, less contestable scope.
