Conciseness

Nearly every section conveys operative knowledge Claude cannot already know (endpoint URL, auth header, parameter shapes, error semantics), with no padded conceptual explanations. The only minor over-explanation is the parenthetical "(the classic indirect prompt-injection vector)" and similar asides, which could be trimmed, matching the 4 anchor of efficient content with minor instances to cut.

Actionability

The skill provides copy-paste-ready curl commands covering both the basic and the framework-parameterized cases, an exact endpoint, a parameter table with shapes and constraints, a concrete response example, and per-status error remediation. This matches the 5 anchor of fully executable commands with examples covering the common cases.

Workflow Clarity

The routing decision is unambiguous (UI-capable host → open_country_brief; explicit text-only or no embedded UI → get_country_brief/endpoint), with a fallback when select_country_view is unavailable and explicit recovery loops (backoff on 429, retry once after 2s on 5xx). As a simple single-action skill with unambiguous routing and explicit error handling, it meets the 5 anchor's feedback-loop standard.

Progressive Disclosure

The ~80-line body is appropriately self-contained for a single API, cleanly sectioned (Authentication, Endpoint, Parameters, Response shape, Worked example, Content safety, Errors, When NOT to use), with external links isolated in a clearly labeled References section. No content belongs in a separate file and navigation is trivial, matching the 5 anchor of well-organized, appropriately split content.

Specificity

The description names the domain ("WorldMonitor country interface") and exactly two actions ("Open the WorldMonitor country interface", "Use the text assessment endpoint"), which matches the anchor for 1-2 concrete actions without comprehensive coverage. It does not list several specific actions, so it is not a 4.

Completeness

The "what" is clear, but there is no "Use when..." trigger clause; the conditional "for explicit text-only requests or clients without embedded UI" governs which mode to use, not when to invoke the skill at all. Per the guideline, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Relevant keywords like "country", "text assessment", and "UI-capable MCP host" are present, but the natural phrases a user would actually say ("country brief", "country report", "briefing on Iran") are missing. This gives some relevant keywords with missing common variations, matching the 3 anchor rather than the fuller coverage of a 4.

Distinctiveness Conflict Risk

The proprietary "WorldMonitor" name gives a clear niche with minimal conflict risk against generic skills, but the trigger terms themselves are weak and would not clearly distinguish it from other country-analysis skills, so it falls between the distinct-niche 5 and the somewhat-specific 3, noticeably above the midpoint.
