wrangler

What problem does it solve? Wrangler CLI flags and configuration fields change frequently, so relying on memorized syntax leads to broken deployments, misconfigured bindings, and accidental overwrites of dashboard settings. This Skill grounds every command and config edit in the project's installed Wrangler version and current official documentation. ## Core Features & Use Cases - Project Inspection: Detects the package manager, installed Wrangler version, framework, and active config file before running any command, so commands always use the project's local Wrangler version. - Documentation-Grounded Commands: Maps each task (deployments, secrets, environments, bindings, rollbacks, migrations) to the correct official Cloudflare docs page or local wrangler --help output. - Safe Change Application: Covers environment inheritance, secret handling, dashboard reconciliation, Vite plugin environments, and rollback limitations to prevent destructive mistakes. - Validation Workflow: Regenerates TypeScript types with wrangler types and uses wrangler deploy --dry-run to verify builds before deployment. - Use Case: You need to add a KV binding to a Worker's staging environment. The Skill checks environment inheritance in your wrangler.jsonc, verifies the binding identifier to avoid automatic provisioning, and validates with a dry-run deploy. ## Quick Start Use the wrangler skill to deploy my Worker to the staging environment and verify the configuration first.
