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.
- Bots and workspaces get tools and MCP servers from their settings
pages; bots also from chips under the chat composer, removable there
- "Every bot" now gives one to every bot now and every new bot; each can
still drop it (attach-every-bot-extensions.ts moves old installs over)
- Status lines: MCP servers record whether they connect, tools whether
their last run worked
- Test connection in the MCP form and a Test panel in the tool form check
the form as it is, without saving
- Hide Google sign-in on the login form
