Conciseness

The body assumes Claude's competence — it never explains known concepts — and carries all comparisons and decision logic in dense tables, with every line being directive guidance; nothing identifiable is padded or trimmable, matching the lean level-5 anchor rather than the minor-trimming level-4 anchor.

Actionability

Guidance is fully executable: copy-paste commands (`claude mcp add --transport http ... && curl .../skills.sh | sh -s -- claude-code && claude mcp login tooluniverse`), exact UI paths for claude.ai, exact tool names (`what_can_i_use`, `get_skill`, `list_skills`), exact env-var names, and specific URLs — matching the level-5 anchor for copy-paste-ready commands covering the common cases.

Workflow Clarity

Seven clearly sequenced sections run from setup identification through connection to error recovery, with verification checkpoints (`claude mcp list`, "Then run the same tool again", "start a new Claude Code session") and explicit feedback loops in the troubleshooting section (re-login for unauthorized, wait-and-retry for restarting service, status URL) — matching the level-5 anchor; no destructive/batch validation cap applies since the workflows are advisory and reversible.

Progressive Disclosure

The single-file skill has no bundle directory to verify; the body is well-organized into seven clear sections and appropriately keeps deep procedures one level deep via clearly signaled `get_skill` references (`tooluniverse-database-logins`, `tooluniverse-share-computer`, `tooluniverse-use-shared-computer`, `tooluniverse-publish-tool`) presented in a table, matching the level-5 well-organized single-file pattern.

Specificity

The description names the domain and concrete functions ("How to use ToolUniverse Connect ... and when to use it instead of ToolUniverse installed on this computer") and enumerates concrete tasks such as connecting Claude/Claude Code/Codex, adding database logins, sharing a model or script, redeeming a TU-SHARE code, publishing a tool, and troubleshooting connection problems — comprehensive coverage matching the level-5 anchor, with no identified gaps that would place it at 4.

Completeness

It explicitly answers both "what" (how to use the hosted service and when to prefer it over a local install) and "when" via an explicit "Use when the user asks..." clause listing nine concrete trigger scenarios, matching the level-5 anchor example pattern.

Trigger Term Quality

Trigger phrases are natural user phrasings ("how to connect Claude, Claude Code or Codex", "why a tool says a login or API key is missing", "a TU-SHARE code", "tools are missing, signed out or not connecting") with synonym coverage of hosted service vs. local install — comprehensive, matching the level-5 anchor.

Distinctiveness Conflict Risk

A clear niche — the specific hosted ToolUniverse Connect service — is explicitly disambiguated from a local ToolUniverse install, and the trigger terms are distinctive to this service, so conflict risk with other skills is minimal.
