Conciseness

The body contains zero concept explanation — every section is commands, parameters with defaults/ranges, or usage tips. The only near-redundancy is a one-line intro restating the description, which is trivial; nothing substantive could be trimmed, matching the 'lean and efficient; every token earns its place' anchor.

Actionability

Copy-paste-ready `mcporter call` commands with concrete argument values cover all three core tools, setup, and the advanced config, with parameter defaults and ranges documented (e.g. `tokensNum (optional, default: 5000) - Range: 1000-50000`). Fully executable guidance covering the common cases matches anchor 5 rather than 4, which implies minor gaps.

Workflow Clarity

This is a simple single-purpose skill whose only process — setup — has an explicit verify-then-fix loop ("Verify mcporter is configured: `mcporter list exa`" / "If not listed: `mcporter config add exa ...`"), and each tool invocation is a single unambiguous action. Per the simple-skill scoring note this qualifies for 5; there are no destructive or batch operations requiring additional checkpoints.

Progressive Disclosure

The short, well-sectioned body keeps core usage inline and offloads patterns to exactly one clearly signaled, one-level-deep reference — "See [examples.md](references/examples.md) for more patterns" — which exists and contains the promised command examples. This matches the clear-overview-with-well-signaled-references anchor; there is no buried or nested content to warrant 4.

Specificity

"Web search for news/info", "code search for docs/examples from GitHub/StackOverflow", and "company research for business intel" list three concrete capabilities with specific targets, matching the 'several specific actions; minor gaps' anchor. It falls short of 5 because the actions are named domains rather than a comprehensive list of concrete operations, and above 3 which requires only 1-2 actions.

Completeness

The "what" is clear (three search modes via Exa MCP) but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the rubric guidelines. It is not 2 because the "what" is specific rather than vague, and not 4 because the "when" is entirely absent rather than merely imprecise.

Trigger Term Quality

Includes good natural keywords users would say — "web search", "news", "code", "docs", "GitHub", "StackOverflow", "company research" — but misses common variations like plain "search", "look up", or "find information about". Good coverage with a few natural terms missing fits anchor 4, not the synonym-level comprehensiveness of 5.

Distinctiveness Conflict Risk

"via Exa MCP" and "No API key needed" carve out a distinct free-search niche, giving mostly distinct triggers with only minor overlap risk against other generic web-search skills. Not 5 because web/code search is a crowded category where overlap with built-in or other search skills remains possible.
