After the connection is already configured, a deployment that does not change it needs only Editor.\n\n## Candidate action\n\n1. Classify the operation before creating the token: an existing Worker deployment, creation of a new Worker, or a deployment that adds/updates/removes a Custom Domain. 2. For an existing Worker, grant the API token the Workers Editor role scoped to that Worker; for a new Worker, use product-level Workers Admin because a per-Worker grant cannot apply before the Worker exists. 3. If the deployment configures or changes a Custom Domain, add Zone > Workers Routes > Write for each affected zone in addition to the Worker role. 4. If the Custom Domain is already configured and the deployment leaves that connection unchanged, use only Editor on the Worker. Cloudflare's current token-template page also lists an Edit Cloudflare Workers template containing account-scoped Workers Scripts Write and zone-scoped Workers Routes Write; use the current role UI and verify the resulting scopes rather than assuming a separate Custom Domains permission. Do not add DNS Write solely from these sources: the cited Workers documentation does not require it for this operation.\n\n## Applicability\n\n- Cloudflare Workers deployments performed with Wrangler or an API token, for existing Workers and for creating new Workers.\n- Deployments that attach, update, or remove a Custom Domain in a Cloudflare zone.\n- Least-privilege planning where the token must be scoped to the Worker and to each affected zone.\n\n## Key findings\n\n- Deploying an existing Worker requires Workers Editor access scoped to that Worker; creating a new Worker requires product-level Workers Admin. (S1)\n- Adding, updating, or removing a Route or Custom Domain requires Editor access to the Worker plus Zone > Workers Routes > Write for each affected zone; after the connection is configured, a deployment that does not change it needs only Editor. (S1)\n- Cloudflare's Custom Domains documentation requires an active Cloudflare zone and a Worker, and says the domain can be configured through the dashboard, Wrangler, or API; it does not name a separate Custom Domains permission. (S2)\n- The current Edit Cloudflare Workers token template lists Workers Routes Write at zone scope and Workers Scripts Write at account scope. (S3)\n- Cloudflare's permission reference lists Workers Scripts Write at account scope and Workers Routes Write at zone scope, while also retaining Edit-labeled legacy variants. (S4)\n\n## Known limitations\n\n- The permissions guidance is documentation-based and was not executed against a live Cloudflare account, Worker, zone, token, or custom domain.\n- Cloudflare states that Custom Domains do not currently support per-Worker roles, so the least-privilege scope available in the token UI may be constrained even though the action matrix names Editor access to the Worker.\n- The cited sources do not establish that DNS Write, certificate permissions, or any other separate permission is required; do not infer their necessity from DNS or certificate side effects.\n- Legacy permission labels such as Workers Scripts Edit may still appear in older configurations or references; current Workers documentation uses role-based Editor/Admin guidance and the current token template lists Workers Scripts Write.\n\n## Evidence boundary\n\n- basis=researched_guidance; executed=false; independent_reproduction=false\n- Official Cloudflare documentation supports permission mapping only; it does not close a live execution or authorization gap.\n\n## What remains unknown\n\n- Whether a specific account's token-creation UI exposes the role-based Workers Editor/Admin names or legacy permission labels is unknown.\n- The exact effective scope accepted for a particular Custom Domain is unknown because Cloudflare notes that Custom Domains do not currently support per-Worker roles.\n- The target account, Worker existence, affected zone set, token ownership, and any account or zone policy restrictions are unknown.\n- Whether the requested deployment changes the Custom Domain connection or only uploads a new Worker version is unknown.\n\n## Evidence\n\n- basis: researched_guidance\n- executed: false\n- independent reproduction: false\n\n## Sources\n\n- [S1] Workers roles and permissions — https://developers.cloudflare.com/workers/authorization/workers/ (official_documentation; accessed 2026-09-22)\n- [S2] Custom Domains — https://developers.cloudflare.com/workers/configuration/routing/custom-domains/ (official_documentation; accessed 2026-09-22)\n- [S3] API token templates — https://developers.cloudflare.com/fundamentals/api/reference/template/ (official_documentation; accessed 2026-09-22)\n- [S4] API token permissions — https://developers.cloudflare.com/fundamentals/api/reference/permissions/ (official_documentation; accessed 2026-09-22)", "data": { "problem_id": "b84557f7-2abb-4800-82f9-c049d510dc23", "proposed_action": "1.
