-**Setup:** Works automatically if OpenCode has Copilot configured and logged in.
+**Setup:** Personal Copilot usage works automatically when OpenCode has Copilot configured and logged in.
 
-**Optional:** For more reliable quota reporting, provide a fine-grained PAT:
+**Personal usage:** No extra setup required. The plugin uses OpenCode auth to query your user billing report.
 
-1. Create a fine-grained PAT at GitHub with **Account permissions > Plan > Read**
-2. Create `copilot-quota-token.json` under OpenCode's runtime config directory (see `opencode debug paths`):
+**Organization usage:** Create `copilot-quota-token.json` under OpenCode's runtime config directory (see `opencode debug paths`).
+
+Organization example:
 
 ```json
 {
   "token": "github_pat_...",
-  "tier": "pro"
+  "tier": "business",
+  "organization": "your-org-slug"
 }
 ```
 
-`username` is optional (kept for backwards compatibility). If provided, it is used only as a fallback for legacy GitHub REST paths.
+For organization-managed Copilot plans such as `business` or `enterprise`, `organization` is required. `username` is optional and is only used as the `?user=` filter on the organization report.
 
-Both fine-grained PATs (`github_pat_...`) and classic PATs (`ghp_...`) should work. Fine-grained PATs must include **Account permissions > Plan > Read**.
+- **Organization PAT permission:** fine-grained PAT with **Organization permissions > Administration > Read**.
 
 Tier options: `free`, `pro`, `pro+`, `business`, `enterprise`
 
+If both OpenCode Copilot auth and `copilot-quota-token.json` are present, the plugin uses the PAT config first.
+
+For personal plans, a PAT is optional. Use it only if you want an explicit tier override for quota totals.
+
+Run `/quota_status` and check `copilot_quota_auth` to confirm `pat_state`, `pat_organization`, candidate paths checked, and `effective_source`/`override`.
