Conciseness

The body is lean and assumes competence — no explanation of concepts Claude already knows, and troubleshooting entries are direct (e.g., 'Verify the invoker role (and any cross-account roles) can describe resources in all configured regions'). It is not a 5 because the MCP-vs-local guardrail section and the top-level MCP note have some redundancy and the security section could be trimmed slightly. It is clearly above 3, which would require unnecessary explanation or padding.

Actionability

Concrete commands and API operations appear throughout — 'aws resiliencehubv2 update-service-function', 'create-service-function-resources', achievability from 'get-service / list-failure-mode-assessments' — and the full SOP with copy-paste commands and examples lives in the reference. It is not a 5 because some body-level commands are shown without their key flags (e.g., --service-arn/--service-function-id for update-service-function), leaving minor gaps if read in isolation. It is not a 3 because nothing is pseudocode or abstract.

Workflow Clarity

The body directs 'follow the procedure exactly' to a well-signaled reference containing a 9-step sequence with explicit validation checkpoints — dependency verification before anything runs, explicit cost confirmation before the billable assessment, polling 'until status is SUCCESS or FAILED', and error-code handling on report generation. It is not a 4 because the delegated procedure includes complete validation and failure-recovery loops rather than just most checkpoints.

Progressive Disclosure

The body is a concise overview with one clearly signaled, one-level-deep reference (references/assessment-workflow.md, which exists in the bundle) linked contextually from the run/interpret section and both troubleshooting entries. It is not a 4 because there is no content that should have been split out left inline, no buried references, and no nesting beyond one level.

Specificity

The description enumerates concrete, distinct actions — 'starting assessments, understanding findings (severity, categories, recommendations), triaging by achievability, working with AI-generated service functions, and resolving findings' — comprehensively covering the skill's capabilities, matching the score-5 anchor of multiple specific actions with comprehensive coverage. It is not a 4 because the action list leaves no notable coverage gaps within the stated scope.

Completeness

Both 'what' (running and interpreting failure mode assessments, triaging, resolving findings) and 'when' ('Applies when the user wants to run an assessment... or has a specific finding and asks how to resolve, remediate, or fix it') are explicit with concrete trigger phrases, plus explicit exclusions. It is not a 4 because the 'when' clause is already fully explicit with multiple concrete trigger scenarios.

Trigger Term Quality

Trigger phrases like 'run an assessment, review findings, or understand failure modes, or has a specific finding and asks how to resolve, remediate, or fix it' are natural user language with good synonym coverage (resolve/remediate/fix). It falls short of 5 because it omits some natural variations users might say (e.g., 'resiliency review', 'weaknesses', 'chaos/reliability analysis') while 'AI-generated service functions' is more jargon than a user trigger.

Distinctiveness Conflict Risk

A clear niche (Resilience Hub v2 failure mode assessments) is reinforced by explicit boundary guidance — 'Does not apply to initial setup (use resilience-hub-getting-started) or FIS experiments' — routing adjacent use cases away. It is not a 4 because the explicit cross-references to sibling skills leave minimal overlap risk.
