Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A dense, high-signal operational skill: correct sequencing with explicit validation checkpoints, non-obvious gotchas (environment inheritance, secrets-as-deployments, rollback limitations), and disciplined deferral of version-sensitive detail to documentation. The only gap is the absence of a few ready-to-run example commands for common cases.

Suggestions

Add a short "common commands" block with two or three concrete, copy-paste-ready invocations (e.g., a minimal wrangler.jsonc skeleton and a `wrangler deploy --dry-run --config <file>` example) so routine cases don't require a docs round-trip.

For the most frequent task (adding a binding), inline one minimal wrangler.jsonc binding snippet so the config-schema.json path has a concrete starting point.

DimensionReasoningScore

Conciseness

Every line delivers non-obvious operational knowledge (e.g., "setting an environment at deploy time does not retarget its flattened config"; "Treat wrangler secret put and secret delete as deployments") with zero padding and no explanation of concepts Claude already knows. Nothing is trimmable, so it exceeds the 4 anchor.

5 / 5

Actionability

Concrete commands and artifacts are given ("wrangler <command> --help", "wrangler types", "wrangler deploy --dry-run", "CLOUDFLARE_ENV", "wrangler/config-schema.json"), but no copy-paste-ready example commands for the most common cases — execution relies on discovering commands via help and docs. This sits between "concrete commands with minor gaps" (4) and "fully executable, copy-paste ready" (5).

4 / 5

Workflow Clarity

A clear four-phase sequence (Inspect the Project, Retrieve, Apply the Change, Validate) with an explicit validation section (dry-run, regenerate types, run typecheck/tests, report unresolved gaps) and error-recovery guidance ("If retrieval is unavailable, state the gap and use available local evidence rather than inventing syntax"). Checkpoints are explicit, not minor, and risky operations get dedicated cautions.

5 / 5

Progressive Disclosure

The body is under 50 lines, well-sectioned, with no bundle files to navigate, and it delegates detail one level deep via a task-to-source table pointing to authoritative Cloudflare docs instead of inlining them — clean navigation with no buried references.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is exemplary: concrete capabilities, natural trigger terms including the wrangler.jsonc extension, explicit what-and-when structure, and a distinct niche. It matches the rubric's good examples in form and quality.

DimensionReasoningScore

Specificity

"Run or troubleshoot Wrangler CLI commands and configure Worker projects for local development, deployment, and Cloudflare resource management" lists multiple concrete actions covering the skill's full domain; there are no evident coverage gaps that would warrant a 4.

5 / 5

Completeness

The what (run/troubleshoot/configure Wrangler and Worker projects) and the when ("Use when editing wrangler.jsonc, running wrangler commands, bumping compatibility dates...") are both explicitly stated with concrete trigger phrases.

5 / 5

Trigger Term Quality

"editing wrangler.jsonc", "running wrangler commands", "bumping compatibility dates", "maintaining a Cloudflare Workers deployment" are natural user phrasings and include the config file extension, matching the comprehensive-synonyms anchor.

5 / 5

Distinctiveness Conflict Risk

The description occupies a clear niche (Wrangler CLI / Cloudflare Workers) with distinct, product-specific triggers, so the risk of firing for an unrelated skill is minimal.
