Pass `cwd` when the caller needs project-local `[permissions.]` entries to be included in the current catalog view. - `experimentalFeature/enablement/set` — patch the in-memory process-wide runtime feature enablement for currently supported feature keys. For each feature, precedence is: cloud requirements > --enable > config.toml > experimentalFeature/enablement/set (new) > code default. Invalid keys will be ignored. - `environment/add` — experimental; add or replace a named remote environment by `environmentId` and `execServerUrl` for later selection by `thread/start` or `turn/start`; optional `connectTimeoutMs` overrides the WebSocket connection timeout; returns `{}` and does not change the default environment. +- `environment/info` — experimental; connect to a configured environment by `environmentId` and return its detected `shell` plus environment-native `cwd`. Connection failures are returned as request errors. - `collaborationMode/list` — list available collaboration mode presets (experimental, no pagination). Built-in presets do not select a model; the Plan preset selects medium reasoning effort. This response omits built-in developer instructions; clients should either pass `settings.developer_instructions: null` when setting a mode to use Codex's built-in instructions, or provide their own instructions explicitly. - `skills/list` — list skills for one or more `cwd` values (optional `forceReload`). - `skills/extraRoots/set` — replace the app-server process runtime extra standalone skill roots. The roots are not persisted; missing directories are accepted and simply load no skills. diff --git a/codex-rs/app-server/src/message_processor.rs b/codex-rs/app-server/src/message_processor.rs index 3322f24d8b77..375307e804f7 100644 --- a/codex-rs/app-server/src/message_processor.rs +++ b/codex-rs/app-server/src/message_processor.rs @@ -1037,6 +1037,9 @@ impl MessageProcessor { ClientRequest::EnvironmentAdd { params, .. } => { self.environment_processor.environment_add(params).await } + ClientRequest::EnvironmentInfo { params, .. } => { + self.environment_processor.environment_info(params).await + } ClientRequest::FsReadFile { params, .. } => self .fs_processor .read_file(params) diff --git a/codex-rs/app-server/src/request_processors.rs b/codex-rs/app-server/src/request_processors.rs index cb0f276d8550..587325c246dd 100644 --- a/codex-rs/app-server/src/request_processors.rs +++ b/codex-rs/app-server/src/request_processors.rs @@ -62,6 +62,9 @@ use codex_app_server_protocol::DynamicToolNamespaceTool;
