Minor Changes

• #11852 ad65efa Thanks @NuroDev! - Add --check flag to wrangler types command

  The new --check flag allows you to verify that your generated types file is up-to-date without regenerating it. This is useful for CI/CD pipelines, pre-commit hooks, or any scenario where you want to ensure types have been committed after configuration changes.

  When types are up-to-date, the command exits with code 0:

  $ wrangler types --check
  ✨ Types at worker-configuration.d.ts are up to date.

  When types are out-of-date, the command exits with code 1:

  $ wrangler types --check
  ✘ [ERROR] Types at worker-configuration.d.ts are out of date. Run `wrangler types` to regenerate.

  You can also use it with a custom output path:

  $ wrangler types ./custom-types.d.ts --check

• #11529 43d5363 Thanks @matthewdavidrodgers! - Add ability to enable higher asset count limits for Pages deployments

  Wrangler can now read asset count limits from JWT claims during Pages deployments,
  allowing users to be enabled for higher limits (up to 100,000 assets) on a per-account
  basis. The default limit remains at 20,000 assets.

• #11755 0f8d69d Thanks @nikitassharma! - Users can now specify constraints.tiers for their container applications. tier is deprecated in favor of tiers.
  If left unset, we will default to tiers: [1, 2].
  Note that constraints is an experimental feature.

Patch Changes

• #11820 b0e54b2 Thanks @MattieTK! - Add AI agent detection to analytics events

  Wrangler now detects when commands are executed by AI coding agents (such as Claude Code, Cursor, GitHub Copilot, etc.) using the am-i-vibing library. This information is included as an agent property in all analytics events, helping Cloudflare understand how developers interact with Wrangler through AI assistants.

  The agent property will contain the agent ID (e.g., "claude-code", "cursor-agent") when detected, or null when running outside an agentic environment.

• #11494 ed60c4f Thanks @jalmonter! - Fix scheduled trigger warning showing undefined port

  When running wrangler dev with a worker that has cron triggers, the warning message displayed an invalid URL like curl "http://localhost:undefined/cdn-cgi/handler/scheduled" because the port wasn't yet determined when the warning was logged.

  Moved the warning to after the proxy server is fully ready, where the actual public URL and port are known.

• #11843 ab3859c Thanks @dario-piotrowicz! - Update the Wrangler autoconfig logic to work with the latest version of Waku

  The latest version of Waku (0.12.5-1.0.0-alpha.1-0) requires a src/waku.server.tsx file instead of a src/server-entry.tsx one, so the Wrangler autoconfig logic (the logic being run as part of wrangler setup and wrangler deploy --x-autoconfig that configures a project to be deployable on Cloudflare) has been updated accordingly.

  Also the way the worker needs to handle static assets has been updated as recommended from the Waku team.

• #11848 0eb973d Thanks @petebacondarwin! - Fix incorrect warning about multiple environments when using redirected config

  Previously, when using a redirected config (via configPath in another config file) that originated from a config with multiple environments, wrangler would incorrectly warn about missing environment specification. This fix ensures the warning is only shown when the actual config being used has multiple environments defined, not when the original config did.
