# Capability catalog

Capabilities are exposed through harness tools and report their real runtime
state. A capability can be registered while unavailable because its model is
not downloaded, does not fit the selected GPU profile, or requires hardware
that is not present.

| Domain | Tools | Execution owner | Typical permission |
| --- | --- | --- | --- |
| Conversation | `chat`, `plan`, `summarize`, `rewrite`, `code` | Harness + QVAC master | read |
| Retrieval | `embed`, `remember`, `ask-my-files`, workspaces | QVAC master + local stores | read/write |
| Vision | screenshot, `look-at-this`, `ocr`, `what-is-this` | Portal + QVAC master | read |
| Speech | `dictate`, `transcribe-file`, `meeting`, `speak`, `clone-voice` | PipeWire + QVAC master | read/write |
| Language | `translate`, `relay-voice` | QVAC master | read |
| Media | `imagine`, `edit-image`, `make-video`, `compose` | Job runner + QVAC master | write |
| Training | `teach-me` | Isolated job + QVAC master | dangerous |
| Lab | `bci`, `robot`, `world` | Explicit lab adapters | read/write/dangerous |
| Desktop | launch, focus, window, clipboard, media, settings | GNOME/GIO/D-Bus | read/write |
| Computer use | `cu.observe`, `cu.find`, `cu.act`, `cu.click`, `cu.type`, `cu.key` | CU session | computer-use |

All QVAC-facing capabilities use the master allowlist and scheduler. The UI
must show unavailable reasons instead of hiding a feature or claiming that a
job ran.
