+/**
+ * Inline OAuth connect card (#3993).
+ *
+ * Rendered in place of {@link ApprovalRequestCard} when the agent calls the
+ * `composio_connect` tool — that tool parks on the same ApprovalGate, so the
+ * request arrives over the identical `approval_request` socket path, but the
+ * surface is a **Connect** button rather than approve/deny. Clicking it runs
+ * `composio_authorize`, opens the OAuth handoff in the browser, and polls
+ * `composio_list_connections` until the toolkit flips to ACTIVE — at which
+ * point it resolves the parked tool call with `approve_once` so the agent
+ * resumes in the same turn. Cancel (or the gate's 10-minute TTL) resolves it
+ * as `deny`.
+ *
+ * Provider-specific required fields (WhatsApp `waba_id`, Jira `subdomain`,
+ * Dynamics 365 `org_name`) are collected inline from the
+ * [`toolkitRequiredFields`] registry before the OAuth handoff — so even
+ * field-gated toolkits connect entirely in-chat rather than failing with a
+ * raw `ConnectedAccount_MissingRequiredFields` (code 612) error. Mirrors the
+ * polling + field-collection contract of `ComposioConnectModal` so the two
+ * connect surfaces behave identically.

 ## Typical flow
 
+0. **Connect first if needed.** If the caller's objective is simply to connect/authorize this toolkit, or you already know it isn't connected, call `composio_connect { toolkit }`, await the result, and report it. `{ connected: true }` → proceed (or you're done, if connecting was the whole task); `{ connected: false }` → the user declined: report that plainly, note they can still connect later via Settings → Connections, and stop — do **not** retry `composio_connect`.
 1. You already have the toolkit's action tools in your tool list — start there. If you need a schema reminder or a slug you don't see, call `composio_list_tools`.
 2. Call the per-action tool (or `composio_execute` with the slug) using the caller's task as your guide.
 3. If the call fails with `[composio:error:insufficient_scope]`, `insufficient authentication scopes`, or `missing required permissions`, do **not** call the service disconnected. Say the connected account is missing the permissions needed for the requested action and point the user to Settings → Connections → the toolkit to reconnect or enable the required scope.
-4. If the call fails with a true authentication / authorization / connection error that is **not** a scope or permission error, stop and return: **"Connection error, try to authenticate"** — the orchestrator will take over and route the user to settings.
+4. If the call fails with a true authentication / authorization / connection error that is **not** a scope or permission error, the toolkit is not connected. Call **`composio_connect`** with your bound `toolkit` to raise an inline connect card and **await its result**:
+   - `{ connected: true }` → the user authorized; retry the original action **once** and continue.
+   - `{ connected: false, declined: true }` (or an error) → the user declined or the card could not be raised. **Only then** return **"Connection error, try to authenticate"** so the orchestrator can route the user to settings.
+   Do **not** print a Settings → Connections instruction yourself when `composio_connect` is available.
 
 ## Rules
 
 - **Never fabricate action slugs.** Pull them from `composio_list_tools` or use the per-action tools already in your list.
 - **Respect rate limits** — Composio and upstream providers both throttle. Back off on errors rather than retrying tightly.
 - **Scope errors are not disconnections.** If Gmail or another connected toolkit returns insufficient scope / missing permissions, report the missing permission plainly and direct the user to Settings → Connections → that toolkit. Never say the toolkit is disconnected for this case.
-- **Auth errors bubble up.** On true auth / connection failures only, reply exactly: `Connection error, try to authenticate`. Do not retry, do not attempt to re-authorise yourself — you have no tools for that.
+- **Auth errors → connect inline first.** On a true auth / connection failure (not a scope error), call `composio_connect { toolkit }` to raise the inline connect card and await it. If it returns `connected: true`, retry the action once. Only if the user declines or the card can't be raised, reply exactly: `Connection error, try to authenticate`. Never paste OAuth URLs or name Composio to the user.
 - **Be precise** — every action expects a specific argument shape. Validate against the schema before calling.
 - **Report results** — state what action was taken and the outcome, including any cost reported by Composio.
