Conciseness

Every sentence carries non-obvious, skill-specific facts (e.g., "next() always targets the original destination... cannot redirect, retry, or fan out"; "Treat a falsy identity (!identity) as anonymous") with no padding and no explanations of concepts Claude already knows. It matches the 5 anchor: lean and efficient, every token earns its place.

Actionability

Guidance is concrete at the API level ("Export a named GatewayMiddleware class extending WorkerEntrypoint from cloudflare:workers", "Implement handle(request, context, next)", "next(request) at most once") with concrete validation commands. It falls short of 5 because there is no inline code example and key implementation details are deferred to external template pages.

Workflow Clarity

The 5-step workflow is clearly sequenced and paired with an explicit Validation section ("Type-check against the installed Gateway types and test the named RPC entrypoint... test a permitted request through a scoped Gateway Forward policy") plus a response-rules checklist. It falls short of 5 because error-recovery feedback loops are delegated to the external guide's troubleshooting steps rather than stated inline.

Progressive Disclosure

The body is under 50 lines with no bundle files, and everything is well organized into clearly signaled sections whose external references (Forward guide, worker templates, context reference, related skills) are one level deep. Under the simple-skill guideline, this earns a 5 with just well-organized sections.

Specificity

The description lists multiple concrete actions ("Build, debug, or review") plus named technical components ("GatewayMiddleware entrypoint, Gateway types, context, and continuation"), giving comprehensive coverage of this niche. It fits the 5 anchor rather than 4 because there are no meaningful gaps in what it claims to cover.

Completeness

The "what" is clearly and specifically stated, but there is no "Use when..." clause or equivalent explicit trigger guidance; the Gateway Forward phrasing only weakly implies when to use it. Per the judging guidelines, a missing 'Use when' clause caps completeness at 3.

Trigger Term Quality

Core natural keywords are present ("Cloudflare Workers", "Gateway", "Forward", "HTTP policies"), which a user in this domain would naturally say. A few common variations are missing (e.g., "Cloudflare One", "Zero Trust", "WARP"), so it falls just short of the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

"Invoked by the Forward action in Gateway HTTP policies" carves out a clear niche, but generic requests like "build a Cloudflare Worker" (non-Gateway) could still trigger this skill, creating minor overlap with closely related Workers skills. This matches the 4 anchor (mostly distinct, minor overlap risk) better than the 5 anchor.
