An error in a resumed assistant + message fails the same Band turn. This is a native lifecycle barrier, not an + instruction-only mitigation, and it does not synthesize a reply or decline. + `turn_timeout_s` covers the whole lifecycle. Timeout, errors and cancellation + close that room's process and terminate its captured descendants before returning; + a subsequent message starts a fresh process rather than inheriting unfinished work. +- **Isolation and state.** Each room owns a native process, persistent session + and workspace. OMP receives the workspace via `--cwd`; the subprocess itself + starts without a supplied cwd. Session state carries `omp_session_id`, + `omp_session_file` and `omp_room_id`. A workspace is not an OS sandbox. +- **External MCP servers.** `mcp_servers` is a name-to-`OmpMcpServer` map; import + that typed model from `band.integrations.omp`. Stdio entries use `command`, + `args`, `env` and optional `cwd`; remote entries use `url`, `headers` and optional + `type` (`http` or `sse`). Relative stdio `cwd` resolves from the room workspace; + relative path-like commands resolve from that server cwd, or the room workspace + when cwd is omitted, before plugin projection. The adapter writes an owner-only temporary + `band-sdk/.mcp.json` plugin overlay and passes it with `--plugin-dir`. The overlay + stays alive until the child closes, then is removed. User profiles and native + credentials are not rewritten. + The SDK requires native connection and tool-mount receipts for every configured + server before inference. It uses the RPC UI event mode and a private startup + setting to enable those receipts without rewriting user settings. Missing or + failed receipts fail startup rather than allowing a model to answer without its + required tools. Native connection and tool failures remain errors, not successful + Band replies. The enclosing turn timeout still bounds startup. +- **Permissions.** `approval_mode="yolo"` bypasses native approval checks without + changing Band platform permissions. Otherwise `resolve_permission` receives + `OmpPermissionRequest(room_id, session_id, title, options)` and returns an + offered option or `None`. Unknown or unoffered choices cancel the request. + Without a resolver, only the exact native `("Approve", "Deny")` select is + approved.

cancel, and OMP treats a cancelled ask as the user interrupting the turn, so any model call to ask aborted the whole prompt and failed the room message. Each session now opts into OMP's structured ask dialog. An ask posts its questions, options and recommendation to the room, mentioning the requester; the post is the turn's reply. Every question is answered at once with an acknowledgement, and the participant's reply resumes the same native session as the next message. A failed post is reported to the model instead; a room the platform stopped still ends the turn. The RPC client also stops admitting host-tool and UI callbacks once shutdown begins, since cleanup can no longer cancel them and they could still post. --- docs/acp.md | 14 ++- src/band/adapters/omp.py | 63 +++++++++- src/band/integrations/omp_room_ask.py | 92 ++++++++++++++ src/band/integrations/omprpc.py | 9 ++ src/band/integrations/ompwire.py | 41 ++++++- tests/adapters/test_omp_adapter.py | 113 ++++++++++++++++++ .../test_reply_boundary.py | 4 + tests/framework_conformance/turnprobes/omp.py | 3 + tests/integrations/omppeer.py | 61 ++++++++++ tests/integrations/test_omprpc.py | 107 +++++++++++++++++ 10 files changed, 500 insertions(+), 7 deletions(-) create mode 100644 src/band/integrations/omp_room_ask.py diff --git a/docs/acp.md b/docs/acp.md index f7fd0c7c2..f806b1f25 100644 --- a/docs/acp.md +++ b/docs/acp.md @@ -232,11 +232,21 @@ text/image tool results.
