Conciseness

The body is mostly lean, assumes Claude's competence, and explains nothing Claude already knows, but the terminal/stop/handoff rule is restated four times (Purpose, 'Terminal By Default', the Output Contract handoff, and 'Stop Rules'), and dependency routing appears in both 'Do Not Activate When' and 'Specialist Routing'. This matches anchor 3 ('could be tightened') rather than 4 because the duplication is a noticeable share of an otherwise short document.

Actionability

For an instruction-only skill the guidance is concrete: an explicit specialist routing table (explore → researcher → dependency-expert), a five-step numbered workflow, and a copy-paste output contract template with named sections. It is not 5 because the template is placeholder-driven and invocation of the named specialists ($ralplan, $ultragoal, $team, executor) is assumed rather than specified.

Workflow Clarity

The Workflow section gives a clearly sequenced five-step process with an explicit stop condition ('Stop when the answer is grounded enough') and an error path ('otherwise report the exact blocker or specialist handoff needed'), plus upward-routing triggers. It falls short of anchor 5 because evidence-quality validation (step 5 / Source-Quality Rules) is stated as directives rather than an explicit validate-and-retry checkpoint loop.

Progressive Disclosure

There are no bundle files (references/, scripts/, assets/ are absent) and none are needed; all content is appropriately in a single well-organized file with clear, navigable sections (Activate When, Do Not Activate When, Specialist Routing, Workflow, Output Contract, Stop Rules). Nothing is inlined that belongs in a separate file, so the well-organized single-file pattern earns the top anchor.

Specificity

The description names the domain ("best-practice research wrapper") but the only action is the generic verb "research" plus the method qualifier "using official/upstream evidence first" — comparable to the anchor 'Names the domain but actions are minimal or generic'. It does not reach 3 because no concrete capabilities (gather, cite, synthesize, hand off) are enumerated.

Completeness

The 'what' is reasonably clear (a bounded research wrapper preferring official/upstream evidence), 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 merely weak.

Trigger Term Quality

It includes relevant natural keywords like "best-practice" and "official/upstream evidence", but misses common variations users would say such as "recommended approach", "current guidance", "standards", "migration notes", or "best practices" (plural). Anchor 3 ('Some relevant keywords but missing common variations or synonyms') is the closest fit.

Distinctiveness Conflict Risk

The phrase "best-practice research wrapper using official/upstream evidence" carves out a somewhat specific niche, but without any when-clause it could overlap with a general research/documentation skill, and the opaque "[OMX]" prefix does nothing to distinguish triggers. Anchor 3 ('Somewhat specific but could still overlap with similar skills') fits best.
