Conciseness

The body is mostly dense project-specific detail, but the "Keyless limit" section re-explains the full Phase 5 upgrade mechanism (attach-secret, gateway injection, re-registration) that Phase 5 already covers, and Phase 5 steps 3–4 pack multiple operations into single over-long sentences. Not a 4: the duplication and run-on sentences go beyond 'minor trimming'; not a 2: there is no generic padding or explanation of concepts Claude already knows.

Actionability

Fully executable throughout: exact grep/cp/vitest commands, the complete JSON manifest entry, and the full `ncl groups config add-mcp-server` invocation with every arg and header pair, plus concrete verification commands (`ncl groups config get`, `docker inspect ... | grep '^APP_URL='`). Common failure cases are covered in Troubleshooting with specific fixes.

Workflow Clarity

Five clearly sequenced phases with explicit validation checkpoints: the manifest guard test in Phase 2, approval-gating semantics explained in Phase 3 ("approval-pending immediately; that is not an error"), config inspection plus agent response check in Phase 4, and a gateway precheck with a defined fallback in Phase 5. Troubleshooting provides feedback loops (rebuild, restart, restore ignore-tool pairs) for the listed failure modes.

Progressive Disclosure

Good structure: the body stays a procedural overview while the upgrade template ([upgrade-instructions.md](upgrade-instructions.md)) and removal procedure ([REMOVE.md](REMOVE.md)) are split out one level deep with clearly signaled links, and the keyless-limit/troubleshooting sections are cross-linked. Not a 5: the referenced bundle files (upgrade-instructions.md, REMOVE.md, tavily-manifest.test.ts) are not present in the bundle as provided, so navigation to them cannot be verified.

Specificity

Names several concrete, specific actions — "Add Tavily Search and Extract as keyless remote MCP tools for selected NanoClaw agent groups" specifies two named tools, the keyless mechanism, and the target (agent groups). Not a 5 because it omits parts of the skill's coverage (bridge install, upgrade path, removal), leaving minor gaps.

Completeness

Explicitly answers both: what ("Add Tavily Search and Extract as keyless remote MCP tools for selected NanoClaw agent groups") and when ("Use when installing Tavily web search or URL extraction without an API key"), with concrete trigger phrases. Clear fit for the top anchor; a 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

"Use when installing Tavily web search or URL extraction without an API key" covers natural trigger phrases users would say: "installing", "Tavily", "web search", "URL extraction", "without an API key". Not a 5 because common synonyms like "scrape/fetch this URL" or "add search to my agents" are absent.

Distinctiveness Conflict Risk

"Tavily" and "NanoClaw agent groups" establish a clear niche with distinct triggers; the keyless/MCP framing further narrows it. Minimal risk of triggering for the wrong skill.
