wrangler

Cloudflare Workers CLI for deploying, developing, and managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, and Secrets Store. Load before running wrangler commands to ensure correct syntax and best practices. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

Quality

Content

72%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 highly actionable, well-organized CLI reference that assumes Claude's competence and avoids concept re-explanation. Its main weaknesses are the absence of validation checkpoints for destructive/batch operations and a monolithic single-file structure with no progressive disclosure of detail into bundle files.

Suggestions

Add explicit validation/confirmation checkpoints before destructive and batch operations (e.g. 'run wrangler deploy --dry-run before wrangler deploy', 'confirm namespace/bucket/database name before delete', 'verify migrations with d1 migrations list after apply').

Split the per-product command references into one-level-deep bundle files under references/ (e.g. references/kv.md, references/r2.md, references/d1.md) and keep SKILL.md as a concise overview pointing to them, to improve progressive disclosure and token efficiency.

Tighten repeated sections (e.g. config-binding blocks and the troubleshooting/best-practices overlap) to reduce inlined volume.

DimensionReasoningScore

Conciseness

The body is dense command/config reference with little concept padding and assumes Claude's competence, though the very large inlined volume (~920 lines) could be trimmed or split.

4 / 5

Actionability

Nearly every section provides copy-paste-ready, executable wrangler commands and complete config blocks covering the common cases for each product.

5 / 5

Workflow Clarity

Operations are organized per product with sequenced commands, but destructive and batch operations (delete, rollback, kv bulk put, d1 migrations apply, secret bulk) lack explicit validation/verification checkpoints, capping this at 3.

3 / 5

Progressive Disclosure

Section headers and a retrieval-sources table provide structure and point to external docs, but the bulk per-product command reference is inlined in one ~920-line file with no bundle split, so content that belongs in separate files is inline.

Description

92%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.

A strong, specific description that names the domain, lists comprehensive capabilities, and provides an explicit load-time trigger. Minor trigger-synonym gaps keep it just short of perfect on keyword coverage.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('deploying, developing, and managing') and enumerates the full product surface (Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, Secrets Store), giving comprehensive coverage.

5 / 5

Completeness

Clearly states what it does (CLI for deploying/developing/managing Workers resources) and gives an explicit when trigger ('Load before running wrangler commands to ensure correct syntax and best practices').

5 / 5

Trigger Term Quality

Natural terms users would say are well covered ('wrangler commands', 'Cloudflare Workers', and product names), but a few common synonyms and file extensions (e.g. 'deploy', 'wrangler.jsonc') are missing.

4 / 5

Distinctiveness Conflict Risk

Targets a clearly distinct niche (Cloudflare Workers / wrangler CLI) with product-specific triggers, so overlap with other skills is minimal.
