Conciseness

The body is a lean ~45-line overview: terse sections (Quick Links, Integration Modes, Hard Guardrails, Chaining, Operations) with zero padding and no explanation of concepts Claude already knows. Every token earns its place, matching the 5 anchor.

Actionability

Some concrete guidance exists — the `zoomCampaignSdk:ready` gate, persisting state by `engagementId`, the `zoomCampaignSdk` pattern, named event/method surfaces in the reference map — but there is no executable code (no SDK init snippet, no postMessage contract example, no campaign SDK invocation), leaving key details missing. This sits between the high-level-hints anchor (2) and the concrete-but-incomplete anchor (3), closer to 3 because specific API names and gating patterns are given.

Workflow Clarity

Integration Modes enumerates three modes and Hard Guardrails supplies implicit checkpoints ('gate calls behind `zoomCampaignSdk:ready`', 'Validate CSP and allow-list settings before debugging logic'), but no end-to-end integration sequence is laid out and checkpoints remain implicit. This matches the 3 anchor (sequence partially present, checkpoints missing/implicit) rather than 4, which would require an explicit ordered workflow with most checkpoints.

Progressive Disclosure

The body is well-structured as an overview with clearly signaled one-level references (Quick Links, Chaining, Operations), but scored against the actual bundle: of the five referenced local files (concepts/lifecycle-and-events.md, examples/app-context-and-state.md, references/web-reference-map.md, troubleshooting/common-issues.md, RUNBOOK.md), only references/web-reference-map.md exists. Four dead links mean navigation as written fails, which is more than the 'minor organization gaps' of the 4 anchor, while the good signaling and sectioning keep it above the 2 anchor's buried/minimal structure.

Specificity

Names the domain ("Zoom Contact Center SDK for Web") and several concrete capability areas ("web chat/video/campaign embeds", "engagement event handling", "app-context integrations", "Smart Embed postMessage workflows"), which matches the 'several specific actions; minor gaps' anchor. It falls short of the 5 anchor because coverage is not fully comprehensive (e.g., initialization/configuration and auth flows are absent) and exceeds the 3 anchor by listing four distinct concrete areas rather than 1-2.

Completeness

Both parts are present: the what ("Zoom Contact Center SDK for Web" plus the capability list) and an explicit trigger clause ("Use for web chat/video/campaign embeds..."). The 'when' is explicit but could be more natural/specific (no 'or when the user mentions...' phrasing), matching the 4 anchor rather than the 5 anchor's fully concrete trigger phrases; the explicit 'Use for' clause keeps it well above the 3 cap.

Trigger Term Quality

Includes natural terms users of this domain would say: "web chat", "video", "campaign", "embeds", "Smart Embed", "postMessage", "app-context". This is good keyword coverage but not comprehensive — common variations like "chat widget", "website chat", or "Zoom CC" are missing, placing it at the 4 anchor rather than 5, while clearly above the 'some relevant keywords but missing variations' level 3.

Distinctiveness Conflict Risk

"Zoom Contact Center SDK for Web" is a clear niche with distinct triggers, but adjacent skills (Zoom Apps SDK, Zoom Meeting SDK) share overlapping vocabulary like "engagement events" and "app-context", creating minor overlap risk with closely related skills — the 4 anchor. It is more distinct than the 3 anchor ('could still overlap with similar skills') but not the minimal-conflict 5 anchor.
