A skill is a runbook: a name, a unique slug, a one-line description of when
it applies, and the markdown body. A run only ever sees the slug and
description (one load_skill tool carries them), and reads the whole body
only when it calls the tool, so a long runbook costs nothing until needed.
Skills are the third extension kind beside MCP servers and custom tools, on
the same botExtensionsSql path, so per-bot, per-workspace and all-bots
grants work the same way, and attachDefaultExtensions hands an every-bot
skill to new bots. load_skill is a reserved tool name, so a custom tool
cannot shadow it, and a built-in wins a clash.
Managed on Settings > Skills; ExtensionRow links each kind to its own page
and a skill never reports a failure, since nothing connects or runs.
Envs had three scopes, general, workspace and computer. A bot had no
scope of its own, so the only way to give one worker a key was to set it
on a computer it happened to share.
The envs table gets a bot_id, and resolution now layers bot over
computer over workspace over general, so a bot's own key wins wherever it
runs. Every computer call site passes the run's bot_id, and grabRunEnvs
does the same for the {{env.KEY}} a custom tool or an MCP server's headers
read.
A bot's and a workspace's settings page can now edit their own envs, in
place, through the same save-env and delete-env routes: sending `scoped`
makes them answer with just that scope instead of the whole install's
overview. Super admins only, like the Environment page.
Two new settings pages, MCPs and Tools. Super admins define them; super
admins and admins attach them to bots, to workspaces (every bot there),
or to every bot. Bots get them in chat replies and tasks.
- Custom tools: a JSON-schema of arguments plus an HTTP request, a script
on the bot's computer, or a prompt, templated with {{args.x}} and
{{env.KEY}}, secrets redacted from results.
- MCP servers: remote (URL and headers) or stdio commands run on the host
with a setup command and an isolated env, in a per-process pool. Tools
are listed into a cache and connect on first call.
- Add, edit, access and try open in modals.
- Markdown, JSON and command fields use twui's AceEditor (CodeEditor),
its scripts loaded on demand.
