Conciseness

The body is lean and assumes competence — a single command, two examples, and short sections with no concept explanations. It stops short of anchor 5 because of minor repetition: the intro sentence ('The controller handles all details: model parameter resolution, openclaw.json generation, storage push, and container recreation') restates the 'What happens' list, and 'You do NOT need to specify context window...' partially repeats step 2.

Actionability

Fully executable, copy-paste-ready commands with real examples ('agt update worker --name alice --model claude-sonnet-4-6'), the exact success output ('worker/<name> configured'), failure causes, and fallback behavior for unknown models. This matches the anchor-5 example pattern of executable commands covering the common cases.

Workflow Clarity

This is a simple single-task skill where the single action is unambiguous, and the skill includes explicit verification checkpoints: the success signal (CLI prints 'worker/<name> configured', no manual restart needed) and a failure path with common causes and escalation to the admin. It is not a destructive or batch operation, so the workflow-clarity cap of 3 does not apply, and the simple-skill exception for scoring 5 is satisfied.

Progressive Disclosure

The skill is under 50 lines, has no bundle files (references/, scripts/, assets/ are absent), and needs none — all content fits in well-organized sections (Usage, What happens, On success, On failure, Unknown models) with no inlined content that belongs in separate files. Per the rubric's simple-skill guidance, this merits a 5.

Specificity

The description names the domain ("Switch a Worker Agent's LLM model") and one concrete action ("via agt CLI"), but does not list several specific actions. It matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive') rather than anchor 4, which requires several specific actions; anchor 2 would mean only a generic domain name with no action verb or tool.

Completeness

Both parts are present: a clear what ("Switch a Worker Agent's LLM model via agt CLI") and an explicit when clause ("Use when the human admin requests changing a Worker's model"), so it clears the anchor-3 cap for missing 'when' guidance. It is not anchor 5 because the when clause offers only one trigger phrasing without the concrete trigger variations and synonyms the top anchor requires.

Trigger Term Quality

Natural terms are present with some variation: "Switch", "changing a Worker's model", "LLM model", "Worker", "admin" — users would plausibly say these. It falls short of anchor 5 because common synonyms like "update", "swap", or "reconfigure the model" are missing, but it clearly exceeds anchor 3 (single keyword, no variations).

Distinctiveness Conflict Risk

The description occupies a clear niche — changing a Worker Agent's model via the agt CLI, triggered by an admin request — with trigger terms unlikely to appear for unrelated skills. It matches anchor 5 (clear niche, distinct triggers, minimal conflict risk); anchor 4 would imply overlap with closely related skills, which is not the case here.
