From 1a55a2e1387073cdc7bb2bc7c8ee31cba1fe5dc3 Mon Sep 17 00:00:00 2001 From: bandzalkin Date: Wed, 21 Oct 2026 17:32:58 +0300 Subject: [PATCH 1/5] feat(omp): add the native OMP adapter OmpAdapter drives omp --mode rpc directly: one process, persistent session and workspace per room, Band tools registered as native host tools, the shared connection guidance installed as an always-apply rule whose presence is verified before inference, background continuations awaited until the native session settles, and native permission selects routed through a resolver. It sits beside the ACP-bridged omp_acp adapter, whose tests and e2e cells are unchanged; the one CI omp binary moves to the native pin, which also serves the ACP cells. --- .github/scripts/setup-omp.sh | 4 +- .github/workflows/e2e.yml | 2 +- README.md | 3 +- docs/acp.md | 94 ++ docs/idle-room-release.md | 4 + examples/omp.py | 87 ++ src/band/adapters/__init__.py | 5 + src/band/adapters/omp.py | 826 ++++++++++++++++++ tests/adapters/omp/__init__.py | 1 + tests/adapters/omp/conftest.py | 12 + tests/adapters/omp/kit.py | 270 ++++++ tests/adapters/omp/test_configuration.py | 52 ++ .../omp/test_permission_projection.py | 201 +++++ tests/adapters/omp/test_permission_records.py | 99 +++ tests/adapters/omp/test_permissions.py | 58 ++ tests/adapters/omp/test_process_cleanup.py | 38 + tests/adapters/omp/test_record_encoding.py | 325 +++++++ tests/adapters/omp/test_tool_bridging.py | 65 ++ tests/adapters/omp/test_turn_ownership.py | 85 ++ tests/baseline/adapter.py | 1 + tests/baseline/registry.py | 4 + tests/e2e/baseline/expected-cells.json | 321 ++++++- .../baseline/fixtures/omp-permission-probe.js | 11 + tests/e2e/baseline/settings.py | 2 + tests/e2e/baseline/smoke/adapters/test_omp.py | 272 ++++++ .../smoke/behavior/test_room_rejoin.py | 1 + .../baseline/smoke/inspection/test_usage.py | 5 +- .../smoke/matrix/test_capability_matrix.py | 1 + .../smoke/matrix/test_context_recall.py | 5 + .../matrix/test_missing_reply_reported.py | 1 + .../baseline/smoke/matrix/test_no_reply.py | 1 + .../smoke/matrix/test_room_workspaces.py | 1 + .../baseline/smoke/samples/omppermission.py | 35 + .../baseline/smoke/samples/sample_agents.py | 1 + tests/e2e/baseline/toolkit/builders.py | 37 + tests/e2e/baseline/toolkit/deps.py | 23 +- tests/e2e/baseline/toolkit/omp_credentials.py | 10 + tests/e2e/baseline/toolkit/provisioning.py | 1 + tests/framework_configs/adapters.py | 45 + tests/framework_conformance/imageprobes.py | 36 +- tests/framework_conformance/outcomeprobes.py | 2 + tests/framework_conformance/stopprobes/omp.py | 125 +++ .../test_backend_stop.py | 3 + tests/framework_conformance/turnprobes/omp.py | 109 +++ tests/integrations/ompprocess/test_launch.py | 7 + tests/integrations/test_omp.py | 7 - tests/toolkit/test_omp_native_policy.py | 76 ++ 47 files changed, 3350 insertions(+), 24 deletions(-) create mode 100644 examples/omp.py create mode 100644 src/band/adapters/omp.py create mode 100644 tests/adapters/omp/__init__.py create mode 100644 tests/adapters/omp/conftest.py create mode 100644 tests/adapters/omp/kit.py create mode 100644 tests/adapters/omp/test_configuration.py create mode 100644 tests/adapters/omp/test_permission_projection.py create mode 100644 tests/adapters/omp/test_permission_records.py create mode 100644 tests/adapters/omp/test_permissions.py create mode 100644 tests/adapters/omp/test_process_cleanup.py create mode 100644 tests/adapters/omp/test_record_encoding.py create mode 100644 tests/adapters/omp/test_tool_bridging.py create mode 100644 tests/adapters/omp/test_turn_ownership.py create mode 100644 tests/e2e/baseline/fixtures/omp-permission-probe.js create mode 100644 tests/e2e/baseline/smoke/adapters/test_omp.py create mode 100644 tests/e2e/baseline/smoke/samples/omppermission.py create mode 100644 tests/framework_conformance/stopprobes/omp.py create mode 100644 tests/framework_conformance/turnprobes/omp.py create mode 100644 tests/toolkit/test_omp_native_policy.py diff --git a/.github/scripts/setup-omp.sh b/.github/scripts/setup-omp.sh index ef0508790..998a0d185 100755 --- a/.github/scripts/setup-omp.sh +++ b/.github/scripts/setup-omp.sh @@ -1,8 +1,9 @@ #!/usr/bin/env bash # Install Bun and pin OMP (@oh-my-pi/pi-coding-agent) for the `backends` e2e lane. +# One global binary serves both the native `omp` and the ACP-bridged `omp_acp` cells. set -euo pipefail -OMP_PACKAGE="${OMP_PACKAGE:-@oh-my-pi/pi-coding-agent@18.2.8}" +OMP_PACKAGE="${OMP_PACKAGE:-@oh-my-pi/pi-coding-agent@18.8.9}" OMP_MIN_BUN="${OMP_MIN_BUN:-1.3.14}" if !

Automatic effort stays automatic rather than being replaced + with the effective level chosen for one turn. + `api_key` requires `model` and reaches the child in that provider's environment + variable; OMP does not read an `OMP_MODEL` environment variable. + `workspace_for_room` and `resolve_permission` are constructor callables. + The native adapter has no ACP `resolve_session_config` callback. +- **Tools and replies.** Canonical Band tools and `additional_tools` are + registered through native `set_host_tools`; results retain text/image content. + Room replies still require `band_send_message`, and deliberate declines use + `band_no_reply`. Native assistant text is optional thought telemetry, not a + room reply. `SimpleAdapter.run_judged_turn` remains the sole turn-judging owner: + native-only output and failed tools followed by narration still reach the + missing-reply verdict. +- **Instructions and attribution.** A private always-apply native rule places Band's + shared communication and completion guidance in OMP's genuine system prompt, + preserving native instructions, user prompt additions and append-file discovery. + A startup command verifies the rule is present before inference, even without + external MCP servers. Disabling rules or using a system-prompt template that + omits them fails startup rather than silently dropping Band's connection policy. + The rule survives restored sessions and prompt rebuilds during background work. + Per-message platform context contains room, requester, roster and contact facts + as JSON. Replayed history is identified as previously handled data; it is not a + new participant handoff. +- **Background settlement.** Prompt acceptance, an initial `prompt_result`, and + `agent_end` with async work remaining are not completion. The reader stays + attached through automatic background continuations and waits for both the + matching prompt outcome and actual native session settlement + (`session_settled` or `get_state.isSettled`). An error in a resumed assistant + message fails the same Band turn. `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. +- **Process close.** A usable reader gets a best-effort abort request bounded to + one second, then stdin closes for EOF while output is drained. The root gets + one second to exit before termination and, if needed, kill, each followed by + another one-second exit wait. Captured descendants are terminated and, if + needed, killed concurrently with the root's EOF grace; Python running behind + a Windows virtualenv launcher is one such descendant. + On POSIX, termination sends `SIGTERM` and kill sends `SIGKILL`. On Windows, + both are forced `TerminateProcess` operations, not graceful signal delivery. + Successful close proves the root was waited for and captured descendants + settled; it does not guarantee exit status zero. Caller cancellation still + waits for shared cleanup, and cleanup failures propagate. +- **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.ompprocess`. 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 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. 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. Unsupported interactive forms are cancelled; this is not approval + for arbitrary UI requests. + A cancelled select posts an independent `omp_permission` call/result pair only + with `Emit.TOOL_CALLS`. Offered selections stay silent; option labels do not + determine an SDK denial outcome. Permission narration records no turn effect + or chat reply. Permission titles and native events share full-registry privacy + redaction, including `mcp__` names and executed `xd://` device writes. Native + names and turn effects still use enabled capabilities plus contacts; withheld + device writes retain their path, other fields and string payload. Unparseable + arguments use a fixed placeholder. Synthetic IDs use `band-permission:`; + metadata retains the original `omp_request_id`. Native event IDs are never + changed or merged with permission records. If encoding a tool-call envelope + fails, the record keeps its event name and ID, scalar `path`/`file_path`/`target` + fields and an opaque arguments placeholder. diff --git a/docs/idle-room-release.md b/docs/idle-room-release.md index 46b54f1cc..c7ef18c67 100644 --- a/docs/idle-room-release.md +++ b/docs/idle-room-release.md @@ -14,6 +14,10 @@ specific qualification blocker.
