Conciseness

The body is largely efficient — tables, terse code snippets, and domain-specific context Claude genuinely lacks (per-space scoping, SigV4-vs-Bearer token semantics). Minor trimmable padding exists: "This skill is the routing brain. Use it when the user has multiple spaces configured..." restates the frontmatter description, and the "Many real teams run more than one AgentSpace" paragraph could be tightened. Not a 5 ("every token earns its place") but clearly above the score-3 anchor's "some unnecessary explanation".

Actionability

Concrete tool calls with parameters and example outputs throughout (e.g. the fully worked Pattern B: aws_devops_agent__investigate(title="ECS 503 errors on checkout-service...", agent_space_id="PROD_ID", priority="HIGH")), plus a routing decision table. Falls short of 5 because Patterns A and C use unresolved placeholders ("<question> | env=prod | <prod IaC context>", "<matched_space_id>") rather than one concrete copy-paste-ready example per pattern.

Workflow Clarity

Multi-step processes are well sequenced: numbered discovery steps (list spaces → per-space summary → offer to persist routing guide), a decision table routing question shapes to strategies, and genuine checkpoints (pre-flight tool check, single-space fallback, "ask the user" for ambiguity, 90s timeout skip). Falls short of 5 because there are no explicit verify/recover loops (e.g. what to do when a chat response is empty or an investigate task fails); the 3-cap for missing validation on destructive/batch operations does not apply since investigations and queries are read-oriented and the skill explicitly warns against default fan-out.

Progressive Disclosure

Sections are well organized and appropriately lean for the main body, but the skill's only progressive-disclosure pointer — "examples/multi-space-walkthrough.md for a fully worked scenario" — is a dangling reference: no examples/, references/, scripts/, or assets/ directory exists in the bundle. The signal is clear but the target is missing, so navigation to the deeper material fails; this sits between the score-3 anchor (references present but not reliably usable) and score-4 (references mostly clear with minor gaps), and the broken file pulls it to 3.

Specificity

"route questions to the right space (prod vs staging vs knowledge), query several spaces in parallel and synthesize, or compare findings across accounts" lists multiple specific concrete actions covering the skill's full scope. Anti-drift check: the score-4 anchor ("several specific actions; minor gaps") is exceeded because coverage is comprehensive for this domain, with no missing capability areas.

Completeness

Both what ("route questions... query several spaces in parallel and synthesize... compare findings across accounts") and when ("Use whenever the user has more than one AgentSpace configured, mentions multiple AWS accounts, or asks something like...") are explicitly stated with concrete trigger phrases. This matches the score-5 anchor example's structure exactly; the score-4 anchor's "'when' could be more explicit" does not fit.

Trigger Term Quality

Natural phrases users would actually say are quoted verbatim: "check both prod and staging", "compare across accounts", "ask the knowledge space", plus "more than one AgentSpace" and "multiple AWS accounts". These are comprehensive synonyms for the multi-space trigger space; the score-4 anchor ("a few natural terms missing") doesn't apply since common variations are explicitly enumerated.

Distinctiveness Conflict Risk

"Coordinate the AWS DevOps Agent across multiple AgentSpaces" carves out a clear niche with triggers ("more than one AgentSpace", "multiple AWS accounts") that are distinct from single-space DevOps Agent skills. Minimal conflict risk; the multi-space condition is an unambiguous discriminator, matching the score-5 anchor.
