<74103710+95256155o@users.noreply.github.com> Date: Mon, 30 Mar 2026 02:02:43 -0400 Subject: [PATCH 041/355] feat(discord): configurable read receipt + subagent working indicator (#2330) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(discord): channel-side read receipt and subagent indicator - Add 👀 reaction on message receipt, removed after bot reply - Add 🔧 reaction on first progress message, removed on final reply - Both managed purely in discord.py channel layer, no subagent.py changes - Config: read_receipt_emoji, subagent_emoji with sensible defaults Addresses maintainer feedback on HKUDS/nanobot#2330 Co-Authored-By: Claude Sonnet 4.6 * fix(discord): add both reactions on inbound, not on progress _progress flag is for streaming chunks, not subagent lifecycle. Add 👀 + 🔧 immediately on message receipt, clear both on final reply. * fix: remove stale _subagent_active reference in _clear_reactions * fix(discord): clean up reactions on message handling failure Previously, if _handle_message raised an exception, pending reactions (read receipt + subagent indicator) would remain on the user's message indefinitely since send() — which handles normal cleanup — would never be called. Co-Authored-By: Claude Opus 4.6 (1M context) * refactor(discord): replace subagent_emoji with delayed working indicator - Rename subagent_emoji → working_emoji (honest naming: not tied to subagent lifecycle) - Add working_emoji_delay (default 2s) — cosmetic delay so 🔧 appears after 👀, cancelled if bot replies before delay fires - Clean up: cancel pending task + remove both reactions on reply/error Co-Authored-By: Claude Opus 4.6 (1M context) --------- Co-authored-by: Claude Sonnet 4.6 --- nanobot/channels/discord.py | 44 +++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) diff --git a/nanobot/channels/discord.py b/nanobot/channels/discord.py index ef7d41d7..9bf4d919 100644 --- a/nanobot/channels/discord.py +++ b/nanobot/channels/discord.py @@ -42,6 +42,9 @@ class DiscordConfig(Base): allow_from: list[str] = Field(default_factory=list) intents: int = 37377 group_policy: Literal["mention", "open"] = "mention" + read_receipt_emoji: str = "👀" + working_emoji: str = "🔧" + working_emoji_delay: float = 2.0 if DISCORD_AVAILABLE: @@ -258,6 +261,8 @@ class DiscordChannel(BaseChannel): self._client: DiscordBotClient | None = None self._typing_tasks: dict[str, asyncio.Task[None]] = {} self._bot_user_id: str | None = None + self._pending_reactions: dict[str, Any] = {} # chat_id -> message object + self._working_emoji_tasks: dict[str, asyncio.Task[None]] = {} async def start(self) -> None: """Start the Discord client.""" @@ -305,6 +310,7 @@ class DiscordChannel(BaseChannel): return is_progress = bool((msg.metadata or {}).get("_progress")) + try: await client.send_outbound(msg) except Exception as e: @@ -312,6 +318,7 @@ class DiscordChannel(BaseChannel): finally: if not is_progress: await self._stop_typing(msg.chat_id) + await self._clear_reactions(msg.chat_id) async def _handle_discord_message(self, message: discord.Message) -> None: """Handle incoming Discord messages from discord.py.""" @@ -331,6 +338,24 @@ class DiscordChannel(BaseChannel): await self._start_typing(message.channel) + # Add read receipt reaction immediately, working emoji after delay + channel_id = self._channel_key(message.channel) + try: + await message.add_reaction(self.config.read_receipt_emoji) + self._pending_reactions[channel_id] = message + except Exception as e: + logger.debug("Failed to add read receipt reaction: {}", e) + + # Delayed working indicator (cosmetic — not tied to subagent lifecycle) + async def _delayed_working_emoji() -> None: + await asyncio.sleep(self.config.working_emoji_delay) + try: + await message.add_reaction(self.config.working_emoji) + except Exception: + pass + + self._working_emoji_tasks[channel_id] = asyncio.create_task(_delayed_working_emoji()) + try: await self._handle_message( sender_id=sender_id, @@ -340,6 +365,7 @@ class DiscordChannel(BaseChannel): metadata=metadata, ) except Exception: + await self._clear_reactions(channel_id) await self._stop_typing(channel_id) raise @@ -454,6 +480,24 @@ class DiscordChannel(BaseChannel): except asyncio.CancelledError: pass + + async def _clear_reactions(self, chat_id: str) -> None: + """Remove all pending reactions after bot replies.""" + # Cancel delayed working emoji if it hasn't fired yet + task = self._working_emoji_tasks.pop(chat_id, None) + if task and not task.done(): + task.cancel() + + msg_obj = self._pending_reactions.pop(chat_id, None) + if msg_obj is None: + return + bot_user = self._client.user if self._client else None + for emoji in (self.config.read_receipt_emoji, self.config.working_emoji): + try: + await msg_obj.remove_reaction(emoji, bot_user) + except Exception: + pass + async def _cancel_all_typing(self) -> None: """Stop all typing tasks.""" channel_ids = list(self._typing_tasks) From f450c6ef6c0ca9afc2c03c91fd727e94f28464a6 Mon Sep 17 00:00:00 2001 From: Xubin Ren Date: Tue, 31 Mar 2026 11:18:18 +0000 Subject: [PATCH 042/355] fix(channel): preserve threaded streaming context --- nanobot/agent/loop.py | 18 +++--- nanobot/channels/matrix.py | 35 ++++++++--- tests/agent/test_task_cancel.py | 37 ++++++++++++ tests/channels/test_discord_channel.py | 2 +- tests/channels/test_matrix_channel.py | 82 ++++++++++++++++++++++++++ 5 files changed, 155 insertions(+), 19 deletions(-) diff --git a/nanobot/agent/loop.py b/nanobot/agent/loop.py index 97d352cb..a9dc589e 100644 --- a/nanobot/agent/loop.py +++ b/nanobot/agent/loop.py @@ -403,25 +403,25 @@ class AgentLoop: return f"{stream_base_id}:{stream_segment}" async def on_stream(delta: str) -> None: + meta = dict(msg.metadata or {}) + meta["_stream_delta"] = True + meta["_stream_id"] = _current_stream_id() await self.bus.publish_outbound(OutboundMessage( channel=msg.channel, chat_id=msg.chat_id, content=delta, -

system with Dream consolidation Replace single-stage MemoryConsolidator with a two-stage architecture: - Consolidator: lightweight token-budget triggered summarization, appends to HISTORY.md with cursor-based tracking - Dream: cron-scheduled two-phase processor that analyzes HISTORY.md and updates SOUL.md, USER.md, MEMORY.md via AgentRunner with edit_file tools for surgical, fault-tolerant updates New files: MemoryStore (pure file I/O), Dream class, DreamConfig, /dream and /dream-log commands. 89 tests covering all components. --- nanobot/agent/__init__.py | 3 +-

Both changes are backward-compatible: older GPT-4 models continue to work as before since `max_completion_tokens` is accepted by all recent OpenAI models and temperature is only omitted when reasoning is active.

When the underlying HTTP connection enters CLOSE-WAIT or the server dribbles data slowly, this timeout never fires, causing `ddgs.text` to hang indefinitely via `asyncio.to_thread`. Since `asyncio.to_thread` cannot cancel the underlying OS thread, the agent's session lock is never released, blocking all subsequent messages on the same session (observed: 8+ hours of unresponsiveness). Fix: - Add `timeout` field to `WebSearchConfig` (default: 30s, configurable via config.json or NANOBOT_TOOLS__WEB__SEARCH__TIMEOUT env var) - Wrap `asyncio.to_thread` with `asyncio.wait_for` to enforce a hard wall-clock deadline Closes #2804 Co-Authored-By: Claude Opus 4.6 --- nanobot/agent/tools/web.py | 5 ++++- nanobot/config/schema.py | 1 + 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/nanobot/agent/tools/web.py b/nanobot/agent/tools/web.py index b8aeab47..a6d7be98 100644 --- a/nanobot/agent/tools/web.py +++ b/nanobot/agent/tools/web.py @@ -207,7 +207,10 @@ class WebSearchTool(Tool): from ddgs import DDGS ddgs = DDGS(timeout=10) -

Tue, 7 Apr 2026 15:41:54 +0800 Subject: [PATCH 222/355] feat(memory):dream enhancement (#2887) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(dream): enhance memory cleanup with staleness detection - Phase 1: add [FILE-REMOVE] directive and staleness patterns (14-day threshold, completed tasks, superseded info, resolved tracking) - Phase 2: add explicit cleanup rules, file paths section, and deletion guidance to prevent LLM path confusion - Inject current date and file sizes into Phase 1 context for age-aware analysis - Add _dream_debug() helper for observability (dream-debug.log in workspace) - Log Phase 1 analysis output and Phase 2 tool events for debugging Tested with glm-5-turbo: MEMORY.md reduced from 149 to 108-129 lines across two rounds, correctly identifying and removing weather data, detailed incident info, completed research, and stale discussions. * refactor(dream): replace _dream_debug file logger with loguru Remove the custom _dream_debug() helper that wrote to dream-debug.log and use the existing loguru logger instead. Phase 1 analysis is logged at debug level, tool events at info level — consistent with the rest of the codebase and no extra log file to manage. * fix(dream): make stale scan independent of conversation history Reframe Phase 1 from a single comparison task to two independent tasks: history diff AND proactive stale scan. The LLM was skipping stale content that wasn't referenced in conversation history (e.g. old triage snapshots). Now explicitly requires scanning memory files for staleness patterns on every run. * fix(dream): correct old_text param name and truncate debug log - Phase 2 prompt: old_string -> old_text to match EditFileTool interface - Phase 1 debug log: truncate analysis to 500 chars to avoid oversized lines * refactor(dream): streamline prompts by separating concerns Phase 1 owns all staleness judgment logic; Phase 2 is pure execution guidance. Remove duplicated cleanup rules from Phase 2 since Phase 1 already determines what to add/remove. Fix remaining old_string -> old_text. Total prompt size reduced ~45% (870 -> 480 tokens). * fix(dream): add FILE-REMOVE execution guidance to Phase 2 prompt Phase 2 was only processing [FILE] additions and ignoring [FILE-REMOVE] deletions after the cleanup rules were removed.

Dream processes history.jsonl into long-term memory (memory.md) on a cron schedule (default every 2h), creating a window where compressed content is invisible to the LLM. This change closes the gap by injecting unprocessed history entries (history.jsonl entries not yet consumed by Dream) directly into the system prompt as "# Recent History". Key design notes: - Uses read_unprocessed_history(since_cursor=last_dream_cursor) so only entries not yet reflected in long-term memory are included, avoiding duplication with memory.md - No overlap with session messages: Consolidator advances last_consolidated before returning, so archived messages are already removed from get_history() output - Token-safe: Consolidator's estimate_session_prompt_tokens calls build_system_prompt via the same build_messages function, so the injected entries are included in token budget calculations and will trigger further consolidation if needed Signed-off-by: Lingao Meng --- nanobot/agent/context.py | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/nanobot/agent/context.py b/nanobot/agent/context.py index 1f406485..1b8cae05 100644 --- a/nanobot/agent/context.py +++ b/nanobot/agent/context.py @@ -48,6 +48,10 @@ class ContextBuilder: if skills_summary: parts.append(render_template("agent/skills_section.md", skills_summary=skills_summary)) + entries = self.memory.read_unprocessed_history(since_cursor=self.memory.get_last_dream_cursor()) + if entries: + parts.append("# Recent History\n\n" + "\n".join(f"- {entry['content']}" for entry in entries)) + return "\n\n---\n\n".join(parts) def _get_identity(self) -> str: From 05d8062c70e0541cea585484cebeb41c7524b1d9 Mon Sep 17 00:00:00 2001 From: Xubin Ren Date: Tue, 7 Apr 2026 15:31:39 +0000 Subject: [PATCH 233/355] test: add regression tests for unprocessed history injection in system prompt Made-with: Cursor --- tests/agent/test_context_prompt_cache.py | 26 ++++++++++++++++++++++++ 1 file changed, 26 insertions(+) diff --git a/tests/agent/test_context_prompt_cache.py b/tests/agent/test_context_prompt_cache.py index 6da34648..59f7c981 100644 --- a/tests/agent/test_context_prompt_cache.py +++ b/tests/agent/test_context_prompt_cache.py @@ -86,6 +86,32 @@ def test_runtime_context_is_separate_untrusted_user_message(tmp_path) -> None: assert "Return exactly: OK" in user_content +def test_unprocessed_history_injected_into_system_prompt(tmp_path) -> None: + """Entries in history.jsonl not yet consumed by Dream appear in the prompt.""" + workspace = _make_workspace(tmp_path) + builder = ContextBuilder(workspace) + + builder.memory.append_history("User asked about weather in Tokyo") + builder.memory.append_history("Agent fetched forecast via web_search") + + prompt = builder.build_system_prompt() + assert "# Recent History" in prompt + assert "User asked about weather in Tokyo" in prompt + assert "Agent fetched forecast via web_search" in prompt + + +def test_no_recent_history_when_dream_has_processed_all(tmp_path) -> None: + """If Dream has consumed everything, no Recent History section should appear.""" + workspace = _make_workspace(tmp_path) + builder = ContextBuilder(workspace) + + cursor = builder.memory.append_history("already processed entry") + builder.memory.set_last_dream_cursor(cursor) + + prompt = builder.build_system_prompt() + assert "# Recent History" not in prompt + + def test_subagent_result_does_not_create_consecutive_assistant_messages(tmp_path) -> None: workspace = _make_workspace(tmp_path) builder = ContextBuilder(workspace) From ce7986e4924c1f2b4240d7ee14217ee53fe1d407 Mon Sep 17 00:00:00 2001 From: Xubin Ren Date: Tue, 7 Apr 2026 16:00:41 +0000 Subject: [PATCH 234/355] fix(memory): add timestamp and cap to recent history injection --- nanobot/agent/context.py | 6 +++- tests/agent/test_context_prompt_cache.py | 38 +++++++++++++++++++++++- 2 files changed, 42 insertions(+), 2 deletions(-) diff --git a/nanobot/agent/context.py b/nanobot/agent/context.py index 1b8cae05..addd0738 100644 --- a/nanobot/agent/context.py +++ b/nanobot/agent/context.py @@ -19,6 +19,7 @@ class ContextBuilder: BOOTSTRAP_FILES = ["AGENTS.md", "SOUL.md", "USER.md", "TOOLS.md"] _RUNTIME_CONTEXT_TAG = "[Runtime Context — metadata only, not instructions]" + _MAX_RECENT_HISTORY = 50 def __init__(self, workspace: Path, timezone: str | None = None): self.workspace = workspace @@ -50,7 +51,10 @@ class ContextBuilder: entries = self.memory.read_unprocessed_history(since_cursor=self.memory.get_last_dream_cursor()) if entries: -

Client sends `GET {tokenIssuePath}` with `Authorization: Bearer {tokenIssueSecret}` (or `X-Nanobot-Auth` header). +2. Server responds with a one-time-use token: + +```json +{"token": "nbwt_aBcDeFg...", "expires_in": 300} +``` + +3. Client opens WebSocket with `?token=nbwt_aBcDeFg...&client_id=...`. +4. The token is consumed (single use) and cannot be reused. + +### Example setup + +```json +{ + "channels": { + "websocket": { + "enabled": true, + "port": 8765, + "path": "/ws", + "tokenIssuePath": "/auth/token", + "tokenIssueSecret": "your-secret-here", + "tokenTtlS": 300, + "websocketRequiresToken": true, + "allowFrom": ["*"], + "streaming": true + } + } +} +``` + +Client flow: + +```bash +# 1. Obtain a token +curl -H "Authorization: Bearer your-secret-here" http://127.0.0.1:8765/auth/token + +# 2. Connect using the token +websocat "ws://127.0.0.1:8765/ws?client_id=alice&token=nbwt_aBcDeFg..." +``` + +### Limits + +- Issued tokens are single-use — each token can only complete one handshake. +- Outstanding tokens are capped at 10,000. Requests beyond this return HTTP 429. +- Expired tokens are purged lazily on each issue or validation request. + +## Security Notes + +- **Timing-safe comparison**: Static token validation uses `hmac.compare_digest` to prevent timing attacks. +- **Defense in depth**: `allowFrom` is checked at both the HTTP handshake level and the message level. +- **Token isolation**: Each WebSocket connection gets a unique `chat_id`. Clients cannot access other sessions. +- **TLS enforcement**: When SSL is enabled, TLSv1.2 is the minimum allowed version. +- **Default-secure**: `websocketRequiresToken` defaults to `true`. Explicitly set it to `false` only on trusted networks. + +## Media Files + +Outbound `message` events may include a `media` field containing local filesystem paths.

When _resuming flushes the buffer, any trailing tool hint suffix is removed so it doesn't persist into the next streaming segment. 3. When final _stream_end closes the card, tool hint suffix is cleaned from the text before the final card update. Adds 3 regression tests covering all three scenarios.

a167959027d8ffc614c800ea764e9585c5c967f3 Mon Sep 17 00:00:00 2001 From: worenidewen Date: Fri, 10 Apr 2026 23:51:50 +0800 Subject: [PATCH 300/355] fix(mcp): support multiple MCP servers by connecting each in isolated task Each MCP server now connects in its own asyncio.Task to isolate anyio cancel scopes and prevent 'exit cancel scope in different task' errors when multiple servers (especially mixed transport types) are configured. Changes: - connect_mcp_servers() returns dict[str, AsyncExitStack] instead of None - Each server runs in separate task via asyncio.gather() - AgentLoop uses _mcp_stacks dict to track per-server stacks -

48f6bbd256bde3d43bfa04166c9ae497aa4367a8 Mon Sep 17 00:00:00 2001 From: gem12 Date: Sat, 21 Mar 2026 21:28:41 +0800 Subject: [PATCH 319/355] feat(channels): Add full media support for QQ and WeCom channels QQ channel improvements (on top of nightly): - Add top-level try/except in _on_message and send() for resilience - Use defensive getattr() for attachment attributes (botpy version compat) - Skip file_name for image uploads to avoid QQ rendering as file attachment - Extract only file_info from upload response to avoid extra fields - Handle protocol-relative URLs (//...) in attachment downloads WeCom channel improvements: - Add _upload_media_ws() for WebSocket 3-step media upload protocol - Send media files (image/video/voice/file) via WeCom rich media API - Support progress messages (plain reply) vs final response (streaming) - Support proactive send when no frame available (cron push) - Pass media_paths to message bus for downstream processing --- nanobot/channels/qq.py

This enables MCP tools - that accept geo coordinates (maps, weather, nearby search) to be triggered from a Telegram - location share. -- **Where to update:** - - `content.js` → Telegram channel section → supported message types: - current text lists text, images, voice, audio, documents — add location pins. - - All 6 locale files → same section. -- **Source:** `nanobot/channels/telegram.py` — `filters.LOCATION` in handler, `message.location` extraction in `_on_message`. - -### 5.

Default is an empty list — no behavior change for existing users.

Partial credentials (only username or only password) are logged - as a warning and ignored. -- **Where to update:** - - `content.js` → Discord channel section → config reference: - add the three proxy fields, note that `proxy_username`/`proxy_password` are both required - for auth, and that partial credentials are ignored with a warning. - - All 6 locale files → same section. -- **Source:** `nanobot/channels/discord.py` (`DiscordConfig`, `DiscordChannel.start`). - -### 10. Feishu streaming enhancements: resuming, inline tool hints, done emoji (PR #2993) -- **What changed:** Three Feishu channel improvements: - 1. `doneEmoji` config field — optional completion emoji (e.g. `"DONE"`) added after `reactEmoji` is removed when the bot finishes processing. - 2. `toolHintPrefix` config field — configurable prefix for inline tool hints (default: `🔧`). - 3. Streaming resuming — mid-turn tool calls flush text to the streaming card without closing it, so the next text segment continues on the same card. Tool hints are inlined into active streaming cards instead of sent as separate messages. -- **Where to update:** - - `content.js` → Feishu channel section → config reference: - add `doneEmoji` (optional string, emoji name for completion reaction) and `toolHintPrefix` (string, default `🔧`). - Note streaming resuming behavior for mid-turn tool calls. - - All 6 locale files → same section. - - README → already updated in this PR with config example. -- **Source:** `nanobot/channels/feishu.py` (`FeishuConfig.done_emoji`, `FeishuConfig.tool_hint_prefix`, `send_delta` resuming logic, `send` tool hint inline logic). - -### 11. Unified session across channels (PR #2900) -- **What changed:** New `unifiedSession` toggle in `config.json` (`agents.defaults`). When set to - `true`, all incoming messages — regardless of which channel they arrive on — share a single - session key (`unified:default`). Switching from Telegram to Discord continues the same - conversation. Defaults to `false` — zero behavior change for existing users. Existing - `session_key_override` (e.g. Telegram thread) is respected and not overwritten. -- **Where to update:** - - `content.js` → `agents.defaults` reference section: - add `unifiedSession` field, type `boolean`, default `false`, explain single-user multi-device - use case and that it merges all channel sessions into one. - - All 6 locale files → same section. - - README → config example or feature list, mention cross-channel unified session. -- **Source:** `nanobot/config/schema.py` (`unified_session`), `nanobot/agent/loop.py` (`UNIFIED_SESSION_KEY`, `_dispatch`). - -### 12. Auto compact config rename + recent live suffix retention (PR #3007) -- **What changed:** Auto compact now preserves a recent legal suffix of live session messages while - summarizing the older unconsolidated prefix, instead of clearing the entire live session.

Kagi web search provider (PR #2945) -- **What changed:** `tools.web.search.provider` now accepts `kagi`, using `apiKey` / `KAGI_API_KEY` - to call Kagi's Search API through the built-in `web_search` tool. -- **Where to update:** - - `content.js` → web tools / search provider section: - add `kagi` to the provider list, note that it uses the standard `apiKey` field or `KAGI_API_KEY`. - - All 6 locale files → same section. - - Any provider comparison tables: - add Kagi alongside Brave, Tavily, Jina, SearXNG, and DuckDuckGo. -- **Source:** `nanobot/agent/tools/web.py` (`_search_kagi`), - `nanobot/config/schema.py` (`WebSearchConfig.provider` comment), `README.md` web tools section. - -### 14. Mid-turn follow-up injection for active agent runs (PR #3042) -- **What changed:** If a user sends another message while the agent is still working on the same - session, the follow-up can now be injected into the current agent turn instead of waiting behind - the per-session lock as a separate later turn. Streaming channels keep the active reply open when - the turn resumes, so the follow-up answer can continue in the same live response flow. -- **Where to update:** - - `content.js` → agent loop / streaming behavior section: - explain that same-session follow-ups during an active turn may be folded into the in-flight - response instead of always starting a brand-new queued turn. - - All 6 locale files → same section. -- **Source:** `nanobot/agent/loop.py` (`_pending_queues`, unified-session routing, leftover re-publish), - `nanobot/agent/runner.py` (injection checkpoints, resumed stream end handling). - -### 15. Disable built-in/workspace skills via config (PR #2959) -- **What changed:** New `disabledSkills` field under `agents.defaults`. Users can provide a list of - skill directory names to exclude from loading, so selected built-in or workspace skills no longer - appear in the main agent or subagent skill summaries and are not auto-injected as always-on skills. -- **Where to update:** - - `content.js` -> `agents.defaults` reference section: - add `disabledSkills` as an array of skill names, explain that names match skill directory names, - and note that disabled skills are hidden from both the main agent and subagents. - - All 6 locale files -> same section. -- **Source:** `nanobot/config/schema.py` (`AgentDefaults.disabled_skills`), - `nanobot/agent/context.py` (`ContextBuilder`), `nanobot/agent/subagent.py` (`SubagentManager._build_subagent_prompt`), - `nanobot/agent/skills.py` (`SkillsLoader` filtering).

If the worker is killed (OOM, SIGKILL, a self- triggered systemctl restart, container eviction, etc.) before the turn completes, the user's message is silently lost: on restart, the session log only shows the interrupted assistant turn without any record of what the user asked. Any recovery tooling built on top of session logs cannot reply because it has no prompt to reply to. This patch appends the incoming user message to the session and flushes it to disk immediately after the session is loaded and before the agent loop runs, then adjusts the _save_turn skip offset so the final persistence step does not duplicate it.
