For MULTI-FILE sites (separate CSS/JS/images) use osirAppCreateUpload + osirAppDeploy with a zip instead. Then poll osirAppStatus until READY.

Requires authentication. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve. The result of the confirmed action contains the generated password EXACTLY ONCE; it can never be retrieved again, so show it to the user immediately (they can change it later with setMailboxPassword). Also share the client settings from the result (IMAP/SMTP/webmail).
```

```

### `osirAppDeploy`

- The name "osirAppDeploy" says "deploy": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
osirAppDeploy: Deploy an app to Osir (free tier) and get a live HTTPS URL; the app runs isolated in a microVM. Deploying an existing app name redeploys it (new version) and applies any secrets set via osirAppSetSecret. A plain static website (HTML/CSS/JS with no framework or build step) is also supported: it is auto-detected and served directly; pass language 'node' for it. To put the app on the user's OWN VPS, server or production box instead, deploy it here first and then call osirAppDeployToVps - never SSH into the box or write an install script. Once an app is on the user's own VPS, redeploying HERE under the same name is how you update it: the platform re-ships it to the box and keeps its domain. Requires authentication.
```

### `osirAppDeployToVps`

- The name "osirAppDeployToVps" says "deploy": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
osirAppDeployToVps: Deploy a live Osir app onto the user's own VPS / server / production box, moving it off the shared free tier. Use this INSTEAD of SSH, a provisioning or install script, nginx/systemd/TLS configuration, or any manual server setup - the platform ships the app to the box itself over its own deploy key, so the assistant needs no shell access and no outbound SSH. This is the ONLY supported way to put an app on a user's own server or a custom domain. TWO WAYS IN. (1) The user already owns a VPS: pass instanceId (from listMyVpsInstances) and NO packageId - this ATTACHES the app to that server, SPENDS NOTHING and needs no confirmation. (2) No server yet: pass packageId (from listVpsPackages) and the call stages a VPS order (COSTS MONEY): returns an actionId; present the price/summary to the user and call executeConfirmedAction only if they approve. Before staging any order this tool checks whether the user ALREADY has a box for this app (its C2 binding, then their own VPS list) and attaches that instead - a retry after a failed move never buys a second server. After the move starts the platform ships the app onto the box server-side, which takes about two minutes; watch it with osirAppStatus ('ownedMove'). Calling this tool again while a move is still running just reports its progress, and calling it after one FAILED retries the ship - unless osirAppStatus says the VPS refused the Osir deploy key or its web ports are taken: then retry only after the user has made the changes that message lists. If the result status is BUILDING or BUILD_FAILED, follow its nextStep. Requires authentication.
```

### `osirAppProvisionDatabase`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text

```

- The name "osirAppSetSecret" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text

Validates the brief and returns 'systemPrompt', the structured design brief and constraints YOU must then follow to write one complete self-contained HTML page, plus 'editRules' for later revisions.

```

### `registerDomain`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

'qa' is an independent black-box check of the LIVE app after deploy: qa.status PASSED means it loaded and worked; FAILED means it deployed but didn't actually work, and qa.findings lists the problems so you can fix and redeploy. 'ownedMove' tracks a move onto the user's own VPS, which leaves tier and status unchanged while it runs: state MOVING (in progress, stage says where, ~2 minutes in total), MOVED (done - tier reads 'owned'), FAILED or REFUSED (follow this result's message: usually call osirAppDeployToVps again to retry, which never orders a second server; but when the VPS refused the Osir deploy key or its web ports are taken, the user must fix the VPS first, and the message says how).
