Conciseness

Mostly high-value platform-specific knowledge Claude would not know (error-code diagnoses, gateway/CORS semantics, credential channels), but the image-deployment polling workflow appears twice nearly verbatim (the gotcha bullet and the "MCP image deployment with polling" section), and CORS and credential guidance is each repeated three or more times. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened'; not 2 because there is no basic-concept padding.

Actionability

Fully executable guidance throughout: copy-paste-ready Event and HTTP Function skeletons (complete server code, scf_bootstrap, package.json), exact MCP calls with action names and parameters, concrete error codes (401 MISSING_CREDENTIALS, InvalidParameter.Cls, CLOUD_REGISTRY_CREDENTIAL_MISSING) paired with diagnosis steps, and specific naming formats like `{layerName}_{当前envId}`. Matches the 'copy-paste ready; covers common cases' anchor.

Workflow Clarity

Clear sequencing (Activation Contract -> decision table -> 5-step "How to use this skill" -> tool map) with explicit validation checkpoints (Change Safety Protocol, Deployment Gate, poll getFunctionDeployStatus to a terminal status, verify listFunctionLogs after role binding) and error-recovery feedback loops (expired status -> getFunctionDetail, credential failure -> env-block guidance). Matches the top anchor including feedback loops for a deployment workflow.

Progressive Disclosure

The seven references/ files are real, substantive, one level deep, contextually linked, and indexed at the bottom — but the body's primary routing hub `./references.md` (referenced four times, including in the Minimal checklist), `checklist.md`, and `tooling-fallback.md` are all linked yet absent from the bundle, breaking the main navigation path. This sits between 'minor organization gaps' (4) and clearly broken reference signaling (3); the dead routing-hub links pull it to 3.

Specificity

Names the domain ("CloudBase function runtime") with three concrete actions ("building, deploying, and debugging") applied to specific artifacts ("Event Functions or HTTP Functions"), matching the 'several specific actions; minor gaps' anchor. Not 5 because three verbs is narrower coverage than the comprehensive multi-action examples; not 3 because it goes beyond naming 1-2 actions.

Completeness

Explicitly answers both what ("guide for building, deploying, and debugging your own Event Functions or HTTP Functions") and when ("This skill should be used when users need application runtime code on CloudBase"). Not 5 because the when-clause uses the abstract phrase "application runtime code" rather than concrete mention-triggers; not 3 because the when guidance is explicit, not merely implied.

Trigger Term Quality

Includes natural phrases users would say such as "Event Functions", "HTTP Functions", "deploying", and "CloudBase", giving good keyword coverage. Not 5 because common synonyms like "serverless", "SCF", or plain "cloud function" are absent; not 3 because coverage extends well beyond a single generic keyword.

Distinctiveness Conflict Risk

Occupies a clear niche (authoring your own function runtime code on CloudBase) and adds an explicit negative boundary ("not when they are merely calling CloudBase official platform APIs") that prevents overlap with API-client skills. Minimal conflict risk.
