From ebd119d43123212891616c9bbdcc06989313aebc Mon Sep 17 00:00:00 2001 From: wsp Date: Thu, 23 Jul 2026 22:14:00 +0800 Subject: [PATCH] feat(flow-chat): reference idle sessions from chat input - Extend the chat input `@` picker to search files, folders, and idle sessions across currently open local and SSH workspaces. - Send selected session locators as structured message metadata and preserve that metadata through the frontend queue. - Materialize bounded, newest-first session transcripts into current-session artifacts only when a turn is dispatched. - Add short collision-safe transcript artifact names, line-range metadata, and a safe-use reminder for agents. - Reject archived, hidden, busy, queued, invalid, or self-referencing sessions. --- .../src/api/remote_workspace_policy.rs | 5 + src/apps/desktop/src/api/session_api.rs | 104 ++++ src/apps/desktop/src/lib.rs | 1 + .../src/agentic/coordination/coordinator.rs | 176 +++++- .../src/agentic/coordination/scheduler.rs | 12 + .../core/src/agentic/persistence/manager.rs | 238 +++++++- .../core/src/agentic/persistence/mod.rs | 2 +- .../src/agentic/session/session_manager.rs | 128 +++- .../src/agentic/session/transcript_render.rs | 14 + .../services/services-core/src/json_store.rs | 32 +- .../services-core/src/session/layout.rs | 21 + .../src/flow_chat/components/ChatInput.tsx | 11 +- .../components/FileMentionPicker.scss | 14 + .../components/FileMentionPicker.tsx | 564 ++++++++---------- .../flow_chat/components/RichTextInput.tsx | 17 +- .../src/flow_chat/hooks/useMessageSender.ts | 33 +- .../flow-chat-manager/MessageModule.ts | 2 + .../flow-chat-manager/PendingQueueModule.ts | 2 + src/web-ui/src/flow_chat/types/flow-chat.ts | 2 + .../api/service-api/SessionAPI.ts | 23 + src/web-ui/src/shared/types/context.ts | 12 + src/web-ui/src/shared/utils/contextPrompt.ts | 4 + 22 files changed, 1093 insertions(+), 324 deletions(-) diff --git a/src/apps/desktop/src/api/remote_workspace_policy.rs b/src/apps/desktop/src/api/remote_workspace_policy.rs index 47fe521e52..693dbbf0cc 100644 --- a/src/apps/desktop/src/api/remote_workspace_policy.rs +++ b/src/apps/desktop/src/api/remote_workspace_policy.rs @@ -1436,6 +1436,10 @@ pub const REMOTE_WORKSPACE_COMMAND_POLICIES: &[(&str, RemoteWorkspacePolicy)] = ), ("search_filenames", RemoteWorkspacePolicy::LegacyUnaudited), ("search_files", RemoteWorkspacePolicy::LegacyUnaudited), + ( + "search_referenceable_sessions", + RemoteWorkspacePolicy::WorkspaceAgnostic, + ), ( "search_get_repo_status", RemoteWorkspacePolicy::RemoteRouted, @@ -2122,6 +2126,7 @@ mod tests { "search_file_contents", "search_filenames", "search_files", + "search_referenceable_sessions", "search_skill_market", "send_background_command_input", "send_mcp_app_message", diff --git a/src/apps/desktop/src/api/session_api.rs b/src/apps/desktop/src/api/session_api.rs index 89f8ba1bd9..c65f7b3ca3 100644 --- a/src/apps/desktop/src/api/session_api.rs +++ b/src/apps/desktop/src/api/session_api.rs @@ -7,15 +7,18 @@ use crate::runtime::{ UiSessionMetadataField, }; use crate::startup_trace::DesktopStartupTrace; +use bitfun_core::agentic::coordination::get_global_scheduler; use bitfun_core::agentic::persistence::{ PersistenceManager, SessionBranchResult, SessionMetadataPage, }; use bitfun_core::infrastructure::PathManager; +use bitfun_core::service::remote_ssh::normalize_remote_workspace_path; use bitfun_core::service::session::{ DialogTurnData, SessionKind, SessionMetadata, SessionStatus, SessionTranscriptExport, SessionTranscriptExportOptions, }; use bitfun_core::service::session_usage::SessionUsageReport; +use bitfun_core::service::workspace::WorkspaceKind; use serde::{Deserialize, Serialize}; use std::sync::Arc; use std::time::Instant; @@ -109,6 +112,31 @@ pub struct ExportSessionTranscriptRequest { pub turns: Option>, } +#[derive(Debug, Clone, Serialize, Deserialize)] +pub struct SearchReferenceableSessionsRequest { + pub query: String, + #[serde(default = "default_session_reference_search_limit")] + pub limit: usize, +} + +fn default_session_reference_search_limit() -> usize { + 30 +} + +#[derive(Debug, Clone, Serialize)] +#[serde(rename_all = "camelCase")] +pub struct SessionReferenceCandidate { + pub session_id: String, + pub session_name: String, + pub workspace_path: String, + #[serde(skip_serializing_if = "Option::is_none")] + pub remote_connection_id: Option, + #[serde(skip_serializing_if = "Option::is_none")] + pub remote_ssh_host: Option, + pub workspace_label: String, + pub last_activity_at: u64, +} + fn default_tools() -> bool { false } @@ -231,6 +259,82 @@ pub async fn list_persisted_sessions( }) } +/// Search lightweight persisted metadata across open local and SSH +/// workspaces.
