Conciseness

The body is lean — no explanation of concepts Claude already knows, a two-sentence overview, and a genuinely useful freshness caveat ('confirm values against current AWS documentation'). It falls short of anchor 5 only because the Files table duplicates the Routing table's coverage of the same 10 files; merging them would trim roughly 10 lines.

Actionability

Directives are concrete and executable ('Read troubleshooting.md — starts with the 5 most common fixes', 'Use alarm-template.ts as a starting point'), and per the instruction-only carve-out absent code is not penalized. It sits at anchor 4 rather than 5 because there is no inline quick-start example — even a trivial request (e.g., a basic Log Insights query or one CLI command) forces loading a reference file first.

Workflow Clarity

The skill's single action — routing a user need to the right reference — is made unambiguous by an exhaustive Routing table with a fallback row ('Spans multiple areas → Read the most specific reference first, then consult others as needed'). No validation checkpoints are applicable since the body involves no destructive or batch operations, so the simple-skill exception applies: the single action is unambiguous.

Progressive Disclosure

Scored against the actual bundle: all 10 referenced files (8 references + 2 assets) exist, and inspection confirms references are exactly one level deep — reference files contain only internal anchors and external AWS doc links, no nested file references. The body is a clear overview with two well-signaled navigation tables (task-to-file routing plus content summaries), matching the anchor-5 structure.

Specificity

Concrete third-person verbs ('Builds, configures, debugs, and optimizes') are backed by an exhaustive enumeration of specific capabilities ('fields, filter, stats, parse, pattern, join, subqueries', 'PutMetricData, EMF, metric filters', 'annotations vs metadata'). Coverage is comprehensive across the domain, matching the anchor-5 example's density; anchor 4 would require minor gaps that are not present.

Completeness

Explicitly answers 'what' (two sentences of concrete capabilities) and 'when' ('Use when the user mentions...'), plus a negative boundary ('Do NOT use for application logging setup, container log drivers, or security threat detection'). This mirrors the anchor-5 exemplar structure; anchor 4 would require a less explicit or specific 'when' clause.

Trigger Term Quality

'Use when the user mentions CloudWatch, Log Insights, alarms, INSUFFICIENT_DATA, dashboards, custom metrics, EMF, X-Ray, traces, sampling, CloudTrail, who deleted, ADOT, OpenTelemetry, observability, monitoring, synthetics, canaries' provides ~19 natural trigger terms including synonyms (traces/sampling/OpenTelemetry, synthetics/canaries) and real user phrases like 'who deleted' and the alarm state 'INSUFFICIENT_DATA'. No common variation appears missing, satisfying the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

A clear niche (AWS observability) with highly distinct service-specific triggers and an explicit exclusion clause that prevents misfires on adjacent topics like application logging or threat detection. Overlap risk from broad words like 'monitoring' is mitigated by the AWS anchoring and the Do-NOT-USE boundary, fitting the minimal-conflict anchor rather than anchor 4's 'minor overlap risk'.
