Always verify Cloudflare/Wrangler/third-party behavior against primary sources before answering or changing

Always verify behavior against primary sources for Cloudflare/Wrangler or any third-party tool/API before answering technical/design questions or making changes. Check the exact installed tool version, its --help output and bundled source, plus official vendor documentation; never guess. Verify defaults, precedence, endpoint behavior, authentication and least-privilege token scopes, account/environment and production semantics, compatibility dates, and network/deployment side effects. For Wrangler investigations, use an isolated scratch dir like /tmp/opencode, install the exact version, inspect its bundled CLI source, and cross-check official Cloudflare docs. Pass API tokens only via environment variables, never in args/logs. Ensure dry-run paths have no network or deployment side effects. Cite exact source locations/URLs and document required permissions; report prioritized CRITICAL/MAJOR/MINOR findings with file:line references and command-based verification.
