description	Wrangler CLI: Workers, KV, tail, deploy, account routing.

Wrangler

Use for Cloudflare Wrangler CLI work: deploys, tails, KV/R2/D1/Queues/Workers, secrets, bindings, and account routing.

Defaults

• Retrieval first for flags/config: wrangler --help, subcommand --help, local node_modules/wrangler/config-schema.json, then Cloudflare docs.
• Prefer repo wrapper: npm exec --yes --package wrangler -- wrangler ... unless repo has its own script.
• wrangler whoami before account-sensitive work.
• ReleaseBar prod account: [e-mail]'s Account / de09342a728de2c25c85cc6b34d68739.
• OpenClaw projects: use OpenClaw account / 91b59577e757131d68d55a471fe32aca. Ask if unsure.

Pitfalls

• Do not invent flags from memory. Wrangler 4 removed/changed some old flags; confirm with --help.
• wrangler kv key list has no --limit; use --prefix and filter locally.
• Run Wrangler KV/list/get/admin reads serially when workerd/local storage starts up; parallel runs can hit SQLite SQLITE_BUSY.
• wrangler tail --sampling-rate must be >0 and <1; use 0.999 for near-full sampling, not 1.
• Stop tails you start. Use a PTY when interactive stop matters; otherwise kill the exact wrangler tail <worker> process.
• Never print secrets. Query exact secret names only; do not dump env.

Quick Commands

npm exec --yes --package wrangler -- wrangler whoami
npm exec --yes --package wrangler -- wrangler deploy
npm exec --yes --package wrangler -- wrangler tail <worker> --format json --sampling-rate 0.999 --search '<term>'
npm exec --yes --package wrangler -- wrangler kv key list --namespace-id <id> --prefix '<prefix>'
npm exec --yes --package wrangler -- wrangler kv key get '<key>' --namespace-id <id>

Account Check

For repo config, read wrangler.toml / wrangler.json(c) before commands. If config account and intended product disagree, stop and ask.
