* refactor: replace persistent subagents with ephemeral spawn tool (#subagent)
- Drop subagents table, remove all persistent subagent infrastructure
- Add 'subagent' session type with parent_session_id on bot_sessions
- Rewrite subagent tool as single 'spawn' tool with parallel execution
- Create system_subagent.md prompt, add _subagent.md include for chat
- Limit subagent tools to file, exec, web_search, web_fetch only
- Merge subagent token usage into parent chat session in reporting
- Remove frontend subagent management page, update chat UI for spawn
- Fix UTF-8 truncation in session title, fix query not passed to agent
* refactor: remove history message page
* refactor: move client_type to provider, replace model fields with config JSONB
- Move `client_type` from `models` to `llm_providers` table
- Add `icon` field to `llm_providers`
- Replace `dimensions`, `input_modalities`, `supports_reasoning` on `models`
with a single `config` JSONB column containing `dimensions`,
`compatibilities` (vision, tool-call, image-output, reasoning),
and `context_window`
- Auto-imported models default to vision + tool-call + reasoning
- Update all backend consumers (agent, flow resolver, handlers, memory)
- Regenerate sqlc, swagger, and TypeScript SDK
- Update frontend forms, display, and i18n for new schema
* ui: show provider icon avatar in sidebar and detail header, remove icon input
* feat: add built-in provider registry with YAML definitions and enable toggle
- Add `enable` column to llm_providers (default true, backward-compatible)
- Create internal/registry package to load YAML provider/model definitions
on startup and upsert into database (new providers disabled by default)
- Add conf/providers/ with OpenAI, Anthropic, Google YAML definitions
- Add RegistryConfig to TOML config (providers_dir, default conf/providers)
- Model listing APIs and conversation flow now filter by enabled providers
- Frontend: enable switch in provider form, green status dot in sidebar,
enabled providers sorted to top
* fix: make 0041 migration idempotent for fresh databases
Guard data migration steps with column-existence checks so the
migration succeeds on databases created from the updated init schema.
When input tokens exceed a configurable threshold after a conversation round,
the system asynchronously compacts older messages into a summary. Cascading
compactions reference prior summaries via <prior_context> tags to maintain
conversational continuity without duplicating content.
- Add bot_history_message_compacts table and compact_id on messages
- Add compaction_enabled, compaction_threshold, compaction_model_id to bots
- Implement compaction service (internal/compaction) with LLM summarization
- Integrate into conversation flow: replace compacted messages with summaries
wrapped in <summary> tags during context loading
- Add REST API endpoints (GET/DELETE /bots/:bot_id/compaction/logs)
- Add frontend Compaction tab with settings and log viewer
- Wire compaction service into both dev (cmd/agent) and prod (cmd/memoh) entry points
- Update test mocks to include new GetBotByID columns
- Rewrite SQL queries to join bot_history_messages with bot_sessions,
supporting chat/heartbeat/schedule usage from a single source
- Update Go handler and CLI command to use unified queries
- Fix daily chart stacking: each session type gets its own bar group
- Add total input/output trend lines to the daily token chart
- Fix summary cards reactivity by restricting aggregation to allDays range
- Fix cache chart reactive dependency tracking by inlining data access
- Add i18n keys for schedule, totalInput, totalOutput
- Default time range changed to 7 days
- Regenerate sqlc, swagger, and SDK
* refactor: introduce multi-session chat support (#session)
Replace the single-context-per-bot model with multiple chat sessions.
Database:
- Add bot_sessions table (route_id, channel_type, title, metadata, soft delete)
- Migrate bot_history_messages from (route_id, channel_type) to session_id
- Add active_session_id to bot_channel_routes
- Migration 0036 handles data migration from existing messages
Backend:
- New internal/session service for session CRUD
- Update message service/types to use session_id instead of route_id
- Update conversation flow (resolver, history, store) for session context
- Channel inbound auto-creates/retrieves active session via SessionEnsurer
- New REST endpoints: /bots/:bot_id/sessions (CRUD)
- WebSocket and message handlers accept optional session_id
- Wire session service into FX dependency graph (agent + memoh)
Frontend:
- Refactor chat store: sessions replaces chats, sessionId replaces chatId
- Session-aware message loading, sending, and pagination
- WebSocket sends include session_id
- New session sidebar component with select/delete
- Chat area header shows active session title + new session button
- API layer updated: fetchSessions, createSession, deleteSession
- i18n strings for session management (en + zh)
SDK:
- Regenerated TypeScript SDK and Swagger docs with session endpoints
* fix: update tests for session refactoring (RouteID → SessionID)
Remove references to removed RouteID and Platform fields from
PersistInput/Message in channel_test.go and service_integration_test.go.
* fix: restore accidentally deleted SDK files and guard migration 0032
- Restore packages/sdk/src/container-stream.ts and extra/index.ts that
were accidentally removed during SDK regeneration
- Wrap migration 0032 route_id index creation in a column existence check
to avoid failure on fresh databases where 0001_init.up.sql no longer
has route_id
* fix: guard migration 0036 data steps for fresh databases
Wrap steps 3-7 (which reference route_id/channel_type on
bot_history_messages) in a column existence check so the migration
is safe on fresh databases where 0001_init.up.sql already reflects
the final schema without those columns.
* feat: add title model setting and auto-generate session titles on user input
- Add title_model_id to bots table (migration 0037) and bot settings API
- Implement async title generation triggered at user message time (not after
assistant response) for faster title availability
- Publish session_title_updated events via SSE event hub for real-time
frontend updates without page refresh
- Fix SSE message event parsing: use direct JSON.parse instead of
normalizeStreamEvent which silently dropped non-chat-stream event types
- Add title model selector in bot settings UI with i18n support
* fix: session-scoped message filtering and URL-based chat routing
- Filter realtime SSE messages by session_id to prevent cross-session
message leakage after page refresh
- Add /chat/:sessionId? route with bidirectional URL ↔ store sync
- Visiting /chat shows a clean state with no bot or session pre-selected
- Visiting /chat/:sessionId loads the specific session directly
- Session switches from sidebar automatically update the URL
- Fix stale RouteID field in dedupe test (removed during session refactor)
* fix: skip cross-channel stream events to prevent session leakage
The bot-level web stream pushes events from all channels (Telegram,
Discord, etc.) without session_id context. Previously these were
rendered inline in the current chat view regardless of session.
Now cross-channel events are ignored in handleLocalStreamEvent;
persisted messages arrive via the SSE message events stream with
proper session_id filtering through appendRealtimeMessage.
* feat: show IM avatars and platform badges on session sidebar
- Add sender_avatar_url to route metadata from identity resolution
- Resolve group avatar and handle via directory adapter for group chats
- JOIN bot_channel_routes in ListSessionsByBot to return route metadata
- Display avatar with ChannelBadge on IM session items (group avatar
for groups, sender avatar for private chats)
- Show @groupname or @username as session sub-label
* fix: clean up RunConfig unused fields, fix skill system and copy bug
- Remove unused RunConfig fields: Tools, Channels, CurrentChannel,
ActiveContextTime
- Remove unused SessionContext fields: DisplayName, ConversationType
- Fix EnabledSkillNames copy bug: make([]string, 0, n) + copy copies
zero elements; changed to make([]string, n)
- Fix prepareRunConfig dead code: remove no-op loop over
CurrentPlatform runes; compute supportsImageInput from model's
InputModalities
- Fix EnabledSkills always nil in system prompt: resolve enabled skill
entries from EnabledSkillNames + Skills
- Fix use_skill tool returning empty response: now returns full skill
content (description + instructions) so LLM gets it in the same turn
- Skip use_skill tool registration when no skills are available
- Conditionally render Skills section in system prompt (hidden when
no skills exist)
* feat: add session type field and bind sessions to heartbeat/schedule executions
- Add `type` column to `bot_sessions` (chat | heartbeat | schedule)
- Add `session_id` to `bot_heartbeat_logs` for per-execution session tracking
- Create `schedule_logs` table binding schedule_id + session_id
- Heartbeat and schedule runs now create independent sessions and persist
agent messages via storeRound, enabling full conversation replay
- Add schedule logs API endpoints (list by bot, list by schedule, delete)
- Update Triggerer interfaces to return TriggerResult with status/usage/model
* refactor: modular system prompts per session type (chat/heartbeat/schedule)
Split the monolithic system.md into three type-specific system prompts
with shared fragments via {{include:_xxx}} syntax, so each session type
gets a focused prompt without irrelevant instructions.
* fix: prevent message duplication after task completion
message_created events from Persist() had an empty platform field because
toMessageFromCreate() didn't extract it from the session. This caused
appendRealtimeMessage to fail the platform === 'web' guard, and
hasMessageWithId to fail because local IDs differ from server UUIDs,
resulting in all messages being appended as duplicates.
- Extract platform from metadata in toMessageFromCreate so published events
carry the correct value
- Pass channel_type: 'web' when creating sessions from the web frontend so
List queries return the correct platform via the session JOIN
* fix: use per-message usage from SDK instead of misaligned step-level usages
Previously, token usage was stored via a separate per-step usages array
that didn't align with messages (off-by-one from prepending user message,
step count != message count). This caused:
- User messages incorrectly receiving usage data
- Usage values shifted across messages in multi-step rounds
- Last assistant message getting the accumulated total instead of its own step usage
- InputTokenDetails/OutputTokenDetails lost during manual accumulation
Now each sdk.Message carries its own per-step Usage (set by the SDK in
buildStepMessages), which is extracted in sdkMessagesToModelMessages and
stored directly via ModelMessage.Usage. The storeRound/storeMessages path
no longer needs external usage/usages parameters.
Also fixes the totalUsage accumulation in runStream to include all detail
fields (InputTokenDetails, OutputTokenDetails).
* feat: add /new slash command to create a new active session from IM channels
Users in Telegram/Discord/Feishu can now send /new to start a fresh
conversation, resetting the session context for the current chat thread.
The command resolves the channel route, creates a new session, sets it as
the active session on the route, and replies with a confirmation message.
* feat: distinguish heartbeat and schedule sessions with dedicated icons in sidebar
Heartbeat sessions show a heart-pulse icon (rose), schedule sessions
show a clock icon (amber), and both display a type label beneath the
session title.
* refactor: remove enabledSkills system prompt injection, keep sorted skill listing
use_skill now returns skill content directly as tool output, so there is
no need to inject enabled skill body text into the system prompt. Remove
the entire enabledSkills tracking chain (RunConfig.EnabledSkillNames,
StreamEvent.Skills, GenerateResult.Skills, ChatRequest/Response.Skills,
enableSkill closures in runStream/runGenerate, prepareRunConfig matching).
Keep a lightweight skills listing (name + description only) in the system
prompt so the model knows which skills are available. Sort entries by name
to guarantee deterministic ordering and maximize KV cache reuse.
* refactor: remove inbox system, persist passive messages directly to history
Replace the bot_inbox table and service with direct writes to
bot_history_messages for group conversations where the bot is not
@mentioned. Trigger-path messages continue to be persisted after the
agent responds (unchanged).
- Drop bot_inbox table and max_inbox_items column (migration 0039)
- Delete internal/inbox/, handlers/inbox.go, command/inbox.go,
agent/tools/inbox.go and the MCP message provider
- Add persistPassiveMessage() in channel inbound to write user
messages into the active session immediately
- Rewrite ListObservedConversationsByChannelIdentity to query
bot_history_messages + bot_sessions instead of bot_inbox
- Extract shared send/react logic into internal/messaging/executor.go;
agent/tools/message.go is now a thin SDK adapter
- Clean up all inbox references from agent prompts, flow resolver,
email trigger, settings, commands, DI wiring, and frontend
- Regenerate sqlc, swagger, and SDK
* feat: add list_sessions and search_messages agent tools
Provide agents with the ability to query session metadata and search
message history across all sessions. search_messages supports filtering
by time range, keyword (JSONB-aware ILIKE), session, contact, and role,
with a default 7-day lookback when no start_time is given.
* feat: inject last_heartbeat time and improve heartbeat search guidance
Query the previous heartbeat's started_at timestamp and pass it through
TriggerPayload into the heartbeat prompt template. Update system prompt
and HEARTBEAT.md checklist to guide agents to use search_messages with
start_time=last_heartbeat for efficient cross-session message review.
* fix: pass BridgeProvider to FSClient and store full heartbeat prompt
FSClient was always created with nil provider, causing all container
file reads (IDENTITY.md, SOUL.md, MEMORY.md, HEARTBEAT.md, etc.) to
silently return empty strings. Expose Agent.BridgeProvider() and wire
it into Resolver. Also fix heartbeat trigger to store the full prompt
template as the user message instead of the literal "heartbeat" string.
* feat: add line numbers to container file read output
Move line-number formatting from the bridge gRPC server to the agent
tool layer so that the raw content stored and transmitted via gRPC
remains clean, while the read_file tool output includes numbered lines
for easier reference by the agent.
* chore(deps): update twilight-ai to v0.3.2
* fix: lint, test
* feat(mcp): workspace container with bridge architecture
Migrate MCP containers to use UDS-based bridge communication instead of
TCP gRPC. Containers now mount runtime binaries and Unix domain sockets
from the host, eliminating the need for a dedicated MCP Docker image.
- Remove Dockerfile.mcp and entrypoint.sh in favor of standard base images
- Add toolkit Dockerfile for building MCP binary separately
- Containers use bind mounts for /opt/memoh (runtime) and /run/memoh (UDS)
- Update all config files with new runtime_path and socket_dir settings
- Support custom base images per bot (debian, alpine, ubuntu, etc.)
- Legacy container detection and TCP fallback for pre-bridge containers
- Frontend: add base image selector in container creation UI
* feat(container): SSE progress bar for container creation
Add real-time progress feedback during container image pull and creation
using Server-Sent Events, without breaking the existing synchronous JSON
API (content negotiation via Accept header).
Backend:
- Add PullProgress/LayerStatus types and OnProgress callback to
PullImageOptions (containerd service layer)
- DefaultService.PullImage polls ContentStore.ListStatuses every 500ms
when OnProgress is set; AppleService ignores it
- CreateContainer handler checks Accept: text/event-stream and switches
to SSE branch: pulling → pull_progress → creating → complete/error
Frontend:
- handleCreateContainer/handleRecreateContainer use fetch + SSE instead
of the SDK's synchronous postBotsByBotIdContainer
- Progress bar shows layer-level pull progress (offset/total) during
pulling phase and indeterminate animation during creating phase
- i18n keys added for pullingImage and creatingContainer (en/zh)
* fix(container): clear stale legacy route and type create SSE
* fix(ci): resolve lint errors and arm64 musl node.js download
- Fix unused-receiver lint: rename `s` to `_` on stub methods in
manager_legacy_test.go
- Fix sloglint: use slog.DiscardHandler instead of
slog.NewTextHandler(io.Discard, nil)
- Handle missing arm64 musl Node.js builds: unofficial-builds.nodejs.org
does not provide arm64 musl binaries, fall back to glibc build
* fix(lint): address errcheck, staticcheck, and gosec findings
- Discard os.Setenv/os.Remove return values explicitly with _
- Use omitted receiver name instead of _ (staticcheck ST1006)
- Tighten directory permissions from 0o755 to 0o750 (gosec G301)
* fix(lint): sanitize socket path to satisfy gosec G703
filepath.Clean the env-sourced socket path before os.Remove
to avoid path-traversal taint warning.
* fix(lint): use nolint directive for gosec G703 on socket path
filepath.Clean does not satisfy gosec's taint analysis. The socket
path comes from MCP_SOCKET_PATH env (operator-configured) or a
compiled-in default, not from end-user input.
* refactor: rename MCP container/bridge to workspace/bridge
Split internal/mcp/ to separate container lifecycle management from
Model Context Protocol connections, eliminating naming confusion:
- internal/mcp/ (container mgmt) → internal/workspace/
- internal/mcp/mcpclient/ → internal/workspace/bridge/
- internal/mcp/mcpcontainer/ → internal/workspace/bridgepb/
- cmd/mcp/ → cmd/bridge/
- config: MCPConfig → WorkspaceConfig, [mcp] → [workspace]
- container prefix: mcp-{id} → workspace-{id}
- labels: mcp.bot_id → memoh.bot_id, add memoh.workspace=v1
- socket: mcp.sock → bridge.sock, env BRIDGE_SOCKET_PATH
- runtime: /opt/memoh/runtime/mcp → /opt/memoh/runtime/bridge
- devenv: mcp-build.sh → bridge-build.sh
Legacy containers (mcp- prefix) detected by container name prefix
and handled via existing fallback path.
* fix(container): use memoh.workspace=v3 label value
* refactor(container): drop LegacyBotLabelKey, infer bot ID from container name
Legacy containers use mcp-{botID} naming, so bot ID can be derived
via TrimPrefix instead of looking up the mcp.bot_id label.
* fix(workspace): resolve containers via manager and drop gateway container ID
* docs: fix stale mcp references in AGENTS.md and DEPLOYMENT.md
* refactor(workspace): move container lifecycle ownership into manager
* dev: isolate local devenv from prod config
* toolkit: support musl node runtime
* containerd: fix fallback resolv.conf permissions
* web: preserve container create progress on completion
* web: add bot creation wait hint
* fix(workspace): preserve image selection across recreate
* feat(web): shorten default docker hub image refs
* fix(container): address code review findings
- Remove synchronous CreateContainer path (SSE-only now)
- Move flusher check before WriteHeader to avoid committed 200 on error
- Fix legacy container IP not cached via ensureContainerAndTask path
- Add atomic guard to prevent stale pull_progress after PullImage returns
- Defensive copy for tzEnv slice to avoid mutating shared backing array
- Restore network failure severity in restartContainer (return + Error)
- Extract duplicate progress bar into ContainerCreateProgress component
- Fix codesync comments to use repo-relative paths
- Add SaaS image validation note and kernel version comment on reaper
* refactor(devenv): extract toolkit install into shared script
Unify the Node.js + uv download logic into docker/toolkit/install.sh,
used by the production Dockerfile and runnable locally for dev.
Dev environment no longer bakes toolkit into the Docker image — it is
volume-mounted from .toolkit/ instead, so wrapper script changes take
effect immediately without rebuilding. The entrypoint checks for the
toolkit directory and prints a clear error if missing.
* fix(ci): address go ci failures
* chore(docker): remove unused containerd image
* refactor(config): rename workspace image key
* fix(workspace): fix legacy container data loss on migration and stop swallowing errors
Three root causes were identified and fixed:
1. Delete() used hardcoded "workspace-" prefix to look up legacy "mcp-"
containers, causing GetContainer to return NotFound. CleanupBotContainer
then silently skipped the error and deleted the DB record without ever
calling PreserveData. Fix: resolve the actual container ID via
ContainerID() (DB → label → scan) before operating.
2. Multiple restore error paths were silently swallowed (logged as Warn
but not returned), so the user saw HTTP 200/204 with no data and no
error. Fix: all errors in the preserve/restore chain now block the
workflow and propagate to the caller.
3. tarGzDir used cached DirEntry.Info() for tar header size, which on
overlayfs can differ from the actual file size, causing "archive/tar:
write too long". Fix: open the file first, Fstat the fd for a
race-free size, and use LimitReader as a safeguard.
Also adds a "restoring" SSE phase so the frontend shows a progress
indicator ("Restoring data, this may take a while...") during data
migration on container recreation.
* refactor(workspace): single-point container ID resolution
Replace the `containerID func(string) string` field with a single
`resolveContainerID(ctx, botID)` method that resolves the actual
container ID via DB → label → scan → fallback. All ~16 lookup
callsites across manager.go, dataio.go, versioning.go, and
manager_lifecycle.go now go through this single resolver, which
correctly handles both legacy "mcp-" and new "workspace-" containers.
Only `ensureBotWithImage` inlines `ContainerPrefix + botID` for
creating brand-new containers — every other path resolves dynamically.
* fix(web): show progress during data backup phase of container recreate
The recreate flow (delete with preserve_data + create with restore_data)
blocked on the DELETE call while backing up /data with no progress
indication. Add a 'preserving' phase to the progress component so
users see "正在备份数据..." instead of an unexplained hang.
* chore: remove [MYDEBUG] debug logging
Clean up all 112 temporary debug log statements added during the
legacy container migration investigation. Kept only meaningful
warn-level logs for non-fatal errors (network teardown, rename
failures).
* refactor(browser): split browser cores via build ARG, add core selector
- Replace playwright official image with ubuntu:noble base in both
docker/Dockerfile.browser and devenv/Dockerfile.browser; install
browsers at build time driven by ARG/ENV BROWSER_CORES
- Add GET /cores endpoint to Browser Gateway reporting available cores
- Proxy GET /browser-contexts/cores in Go handler to Browser Gateway
- Add `core` field to BrowserContextConfigModel and GatewayBrowserContext;
context creation selects the appropriate browser instance by core
- Frontend context-setting page fetches available cores and renders a
core selector; saves core as part of the config JSON
- install.sh prompts for browser core selection and writes BROWSER_CORES
to .env; builds the browser image locally before docker compose up
- Regenerate OpenAPI spec and TypeScript SDK
* fix: lint
* feat(container): add explicit data workflows and snapshot rollback
Make container upgrades and recreation data-safe by adding explicit preserve, export, import, restore, and rollback flows across the backend, SDK, and web UI.
* fix(container): resolve go lint issues
Fix formatting and lint violations introduced by the container data workflow changes so the Go CI lint job passes cleanly.
* feat(models): add per-model probe testing and auto-detect in UI
Move health probes from provider level to model level for precise
testing with real model_id and client_type. Provider test is now a
simple reachability check.
Backend:
- Add POST /models/:id/test endpoint that probes the model's provider
using its actual model_id and client_type
- Add model healthcheck checker for bot health checks (chat/memory/embedding)
- Simplify provider test to reachability-only
Frontend:
- Auto-probe models on mount with status indicator (green/yellow/red dot + latency)
- Auto-probe provider reachability on load and on provider switch
- Fix missing faBolt icon registration
- Manual re-probe via refresh button
Closes#117
* fix(models): increase probe timeout to 15s for slow providers
Some providers (e.g. DashScope) exceed the 5s probe timeout, causing
false-negative "context deadline exceeded" errors. Increase per-probe
timeout to 15s and healthcheck overall timeout to 30s.
* fix(sdk): regenerate exports after merge conflict
Resolve duplicate SDK exports introduced by merge conflict resolution so the web build can compile again while preserving new model probe endpoints.
* feat: add email service with multi-adapter support
Implement a full-stack email service with global provider management,
per-bot bindings with granular read/write permissions, outbox audit
storage, and MCP tool integration for direct mailbox access.
Backend:
- Email providers: CRUD with dynamic config schema (generic SMTP/IMAP, Mailgun)
- Generic adapter: go-mail (SMTP) + go-imap/v2 (IMAP IDLE real-time push via
UnilateralDataHandler + UID-based tracking + periodic check fallback)
- Mailgun adapter: mailgun-go/v5 with dual inbound mode (webhook + poll)
- Bot email bindings: per-bot provider binding with independent r/w permissions
- Outbox: outbound email audit log with status tracking
- Trigger: inbound emails push notification to bot_inbox (from/subject only,
LLM reads full content on demand via MCP tools)
- MailboxReader interface: on-demand IMAP queries for listing/reading emails
- MCP tools: email_accounts, email_send, email_list (paginated mailbox),
email_read (by UID) — all with multi-binding and provider_id selection
- Webhook: /email/mailgun/webhook/:config_id (JWT-skipped, signature-verified)
- DB migration: 0019_add_email (email_providers, bot_email_bindings, email_outbox)
Frontend:
- Email Providers page: /email-providers with MasterDetailSidebarLayout
- Dynamic config form rendered from ordered provider meta schema with i18n keys
- Bot detail: Email tab with bindings management + outbox audit table
- Sidebar navigation entry
- Full i18n support (en + zh)
- Auto-generated SDK from Swagger
Closes#17
* feat(email): trigger bot conversation immediately on inbound email
Instead of only storing an inbox item and waiting for the next chat,
the email trigger now proactively invokes the conversation resolver
so the bot processes new emails right away — aligned with the
schedule/heartbeat trigger pattern.
* fix: lint
