Tools Hub

Tools Hub

ChatHub includes a dedicated utility workspace:

• On desktop, select the Tools Wrench icon in the left sidebar, then choose a tool from the sub-navigation panel.
• On mobile, select More in the bottom navigation, choose Tools, then use the menu button in the page header to switch between tools. The compact tool drawer closes after a selection.

Chat conversations also expose an Agent Skills picker beside the tool picker. Skills are user-installed instruction bundles; the picker and hidden load_skill builtin use the same lazy-loading contract described in Agent Skills.

Built-in Tools

Sandbox (chat tool)

Runs shell commands, git, Node.js, and Python in a Linux container for that conversation, not in the browser. Enable Sandbox in the assistant's tool picker. Operators deploy Sandbox (OpenSandbox) (OPENSANDBOX_SERVER_URL and OPENSANDBOX_IMAGE). If those are unset, the tool returns a configuration error and the model continues.

• The code and its result appear inline: standard output/error and any files or plots the code produced (images render; other files download).
• Long output is capped and marked as truncated so a runaway program can't freeze the page.
• If a run produces nothing, a "no output" note is shown; if it fails, the error is shown instead of a blank result.
• A run that hangs times out after 60 seconds unless SANDBOX_TIMEOUT or the model's timeout says otherwise.
• Listing a name in packages does not install it. Install with a shell command inside the sandbox, or add the package to docker/opensandbox and rebuild the image. Missing imports fail as ordinary Python errors.
• Attach the spreadsheet or document to the chat (paperclip). Knowledge Base-only files are not copied into the sandbox. See Sandbox (OpenSandbox) for the server, the image, and packages.
• Graphile runs Sandbox in the background. Enabling the tool does not force the whole reply onto the connected tab. A portal-thread run uses that thread’s files, not sibling threads.

Picbed

Image and video hosting tool at /tools/picbed:

• Upload one or more images or videos via file select, drag-and-drop, or Ctrl+V / Command+V paste
• Videos may be up to 20 MiB, inclusive; larger videos and unsupported files are skipped while valid files in the same batch continue
• Auto-copies successful URLs to the clipboard, one URL per line
• Responsive media pagination (20 per page) with numbered desktop controls, compact mobile controls, direct page entry, and first/last-page jumps
• Lightbox image preview and native inline video controls without autoplay
• Deleting a media record requires confirmation and reports success or failure; failed items remain in the gallery
• S3-backed storage

Picbed media and upload batches belong to the active account. Signing out or switching accounts immediately clears the visible gallery and cancels any in-progress batch before the new account loads. If an account changes after a file reaches object storage, ChatHub does not create that media record for the new account; upload the file again after the account switch finishes.

Requires S3 environment variables:

S3_ACCESS_KEY_ID=...
S3_SECRET_ACCESS_KEY=...
S3_ENDPOINT=...
S3_BUCKET=...
S3_REGION=...

API Tester

REST API client at /tools/apitest:

• All HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS)
• Auth: None / Bearer Token / Basic Auth
• Request headers editor, body editor with JSON formatter
• Response viewer with status code, timing, pretty-printed JSON, raw toggle
• Stateless — no database required

Password Generator

Utility at /tools/password for generating secure passwords.
