Minor Changes

• #​15113 b8fd112 Thanks @​BSFishy! - Add local dev simulation for Cloudflare Access ctx.access.getIdentity()

  You can now configure a mock Cloudflare Access identity in wrangler.json so that ctx.access.getIdentity() returns it during local development.

  // wrangler.json
  {
    "access": {
      "dev": {
        "aud": "my-app-aud-tag",
        "identity": {
          "email": "user@example.com",
          "name": "Test User"
        }
      }
    }
  }

• #​15152 f0f2054 Thanks @​GregBrimble! - [private beta]: Updates the --ignore-defaults flag to --ignore-base-config on wrangler preview commands.

  --ignore-base-config now only takes effect on Preview creation, rather than on each deployment, since Preview base configuration is now copy-on-create rather than inherit-on-deploy.

• #​14872 339509d Thanks @​dario-piotrowicz! - Add automatic update prompts for out-of-date Cloudflare agent skills

  When Cloudflare skills were previously installed by Wrangler and the upstream cloudflare/skills repository has newer content, Wrangler now offers to update them after eligible commands complete.

  To reduce prompt fatigue, the update check only runs once a month (30 days since the last install or update). Declining suppresses the prompt until the next upstream change.

  When declining an update, Wrangler offers the option to permanently disable future update prompts. This preference is stored globally in ~/.wrangler/agents-skills-install.jsonc. The WRANGLER_NO_SKILLS_UPDATE_PROMPTS=true environment variable can also be used to suppress prompts. The --install-skills flag remains available regardless of these settings.
