e8a97a2cbb fix: add stream debug visibility for tool calls and UUID gap detection (#264)
Tool call events between assistant messages were invisible in [Stream]
debug output, making it hard to understand message finalization timing.

- Add sawNonAssistantSinceLastUuid tracking to warn when assistant UUID
  changes with no visible tool_call/reasoning events in between
- Replace [Bot] tool logging with [Stream]-prefixed structured summaries
  (>>> TOOL CALL, <<< TOOL RESULT) for greppable output
- Bridge DEBUG=1 to DEBUG_SDK=1 so SDK-level dropped wire messages are
  visible when debugging

f5371a9ba7 feat: add group gating to Telegram, Discord, and Slack (#258) (#265)
WhatsApp and Signal already had groups config with requireMention and
group allowlists. This brings the same pattern to the remaining three
channels, giving operators consistent control over which groups the bot
participates in and whether mentions are required.

- New `groups` config for Telegram, Discord, Slack (per-group allowlist
  with requireMention, wildcard support)
- Telegram: standalone gating module with entity, text, command, and
  regex mention detection; applied to text, voice, and attachment handlers
- Discord: inline gating using native message.mentions API
- Slack: gating in message handler (drops non-mentions) and app_mention
  handler (allowlist check); helper methods on adapter
- Signal: pass wasMentioned through to InboundMessage (was detected but
  never forwarded)
- Config wiring: groups/mentionPatterns forwarded from main.ts to all
  adapter constructors
- 17 new tests for Telegram gating

df18cba565 feat: configurable displayName prefix for agent messages in group chats (#255)
Add optional displayName field to agent config. When set, outbound
agent responses are prefixed (e.g. "💜 Signo: Hello!").

dad510150a fix: prevent duplicate Telegram messages on "not modified" edit (#254)
* fix: prevent duplicate Telegram messages on "not modified" edit

When streaming completes and the final editMessage call sends identical
content, Telegram returns "message is not modified". The catch block
treated this as a real failure and bubbled up to bot.ts, which fell back
to sending the response as a brand-new message -- causing duplicates.

Now the Telegram adapter silently returns on "message is not modified"
since the content is already correct.

0dbd743f7f feat: add listening mode for groups (#208)
Add `listeningGroups` config option (per-channel, same pattern as
`instantGroups`) where the bot periodically reads group messages and
sends them to the Letta agent for memory updates, but force-suppresses
response delivery unless the bot is explicitly mentioned.

- Add `isListeningMode` field to `InboundMessage`
- Add `listeningGroups` to all 5 channel configs
- Map `listeningGroups` to env vars in `configToEnv()`
- Rename `fixInstantGroupIds` to `fixLargeGroupIds` to also fix
  `listeningGroups` entries (Discord snowflake precision fix)
- Build `listeningGroupIds` set and pass to bot
- Tag messages as listening mode in `processGroupBatch()` when group
  is in listening mode and bot wasn't mentioned
- In `processMessage()`: skip typing indicator, heartbeat target
  update, recovery error messages, and force-suppress response
  delivery for listening mode messages
- Add `[OBSERVATION ONLY]` header to batch envelope for listening mode
- Document in lettabot.example.yaml

d52ea4e855 fix: create new conversation when no stored conversation ID exists (#245) (#250)
When an agent ID is configured but no conversation ID is stored, LettaBot
previously tried to resume the agent's default conversation via resumeSession().
If that default conversation was deleted or never created (e.g., after
migrations), the CLI exited with "Conversation default not found" and the bot
never replied to messages.

The fix changes getSession() to call createSession() instead of resumeSession()
when there's no stored conversation ID, ensuring a new conversation is always
created in this case.

9c0228d414 fix: recover from active runs stuck on approval (#249)
* fix: recover from active runs stuck on approval

recoverOrphanedConversationApproval() only resolved approvals from
terminated (failed/cancelled) or abandoned (completed/requires_approval)
runs. Active runs with status=running and stop_reason=requires_approval
were skipped, even though they block the entire conversation.

This happens when the CLI's HITL approval flow leaves a pending approval
that no client will resolve (e.g. agent triggered via ADE, user walked
away). Every subsequent message fails with success=false.

Now also handles running+requires_approval: rejects the approval and
cancels the stuck run so lettabot can proceed.

Fixes the recovery path for all three call sites: pre-send check,
CONFLICT catch, and error-result retry.

Written by Cameron ◯ Letta Code

"The best error message is the one that never shows up." -- Thomas Fuchs

* fix: use cancelRuns return value for accurate diagnostics

Check boolean return from cancelRuns() instead of always logging
success. Details string now shows "(cancel failed)" when it didn't
work.

* fix: detect terminal errors and retry with recovery in bot.ts

Monkey patch until SDK issue letta-code-sdk#31 is resolved.

1. Detect terminal errors (success=false OR error field), not just
   empty-success. Both trigger orphan recovery + retry.

2. Blind retry on terminal error when no orphaned approvals found --
   client-side approval failures may leave no detectable record.

3. sendToAgent() throws on terminal error instead of returning empty
   string. Background callers get actionable errors.

* test: add tests for approval recovery including stuck runs

7 tests covering recoverOrphanedConversationApproval():

- Recovery from failed run
- Recovery from stuck running+requires_approval (with cancel)
- Already-resolved approvals skipped
- Healthy running run not touched

* fix: gate retry on sentAnyMessage to prevent duplicate delivery

Codex review caught that finalizeMessage() clears the response buffer
on type changes, so hasResponse could be false even when output was
already sent. This caused duplicate retries with potential side effects.

to !hasResponse before retrying.

deb1c4532a feat: add POST /api/v1/chat endpoint for agent messaging (#242)
* feat: add POST /api/v1/chat endpoint for sending messages to agents

Adds an HTTP endpoint that accepts a JSON message, sends it to the
lettabot agent via sendToAgent(), and returns the agent's response.
This enables external systems (e.g. server-side tools in other agents)
to communicate with lettabot programmatically.

- Add ChatRequest/ChatResponse types
- Add AgentRouter interface extending MessageDeliverer with sendToAgent()
- Implement AgentRouter on LettaGateway with agent-name routing
- Add POST /api/v1/chat route with auth, validation, and JSON body parsing

Written by Cameron ◯ Letta Code

"The most profound technologies are those that disappear." -- Mark Weiser

* feat: add SSE streaming support to /api/v1/chat endpoint

When the client sends Accept: text/event-stream, the chat endpoint
streams SDK messages as SSE events instead of waiting for the full
response. Each event is a JSON StreamMsg (assistant, tool_call,
tool_result, reasoning, result). The result event signals end-of-stream.

- Export StreamMsg type from bot.ts
- Add streamToAgent() to AgentSession interface and LettaBot
- Wire streamToAgent() through LettaGateway with agent-name routing
- Add SSE path in chat route (Accept header content negotiation)
- Handle client disconnect mid-stream gracefully

- 6 tests for gateway sendToAgent/streamToAgent routing

6f5a322840 fix: clear WhatsApp typing indicator after response (#243)
WhatsApp's "typing..." indicator lingers for 15-25 seconds after the bot
finishes responding because there was no way to clear it. This adds
stopTypingIndicator() which sends a "paused" presence update to
immediately dismiss it.

- stopTypingIndicator?() added to ChannelAdapter interface (optional)
- WhatsApp adapter implements it via sendPresenceUpdate("paused")
- bot.ts calls it in the finally block after stream processing

5f7cdd3471 feat: XML response directives via <actions> wrapper block (#239)
Agents can now include an <actions> block at the start of their text
response to perform actions without tool calls. The block is stripped
before the message is delivered to the user.

Example:
  <actions>
    <react emoji="thumbsup" />
  </actions>
  Great idea!
  → Sends "Great idea!", reacts with thumbsup

- New directives parser (src/core/directives.ts) finds <actions> block
  at response start, parses self-closing child directives inside it
- addReaction() added to ChannelAdapter interface (Telegram, Slack,
  WhatsApp already implement it)
- Streaming holdback covers the full <actions> block duration (prefix
  check + incomplete block detection), preventing raw XML from flashing
- Directive execution extracted to executeDirectives() helper (no
  duplication between finalizeMessage and final send paths)
- Message envelope includes Response Directives section so all agents
  learn the feature regardless of system prompt
- System prompt documents the <actions> block syntax
- 19 unit tests for parser and stripping

Significantly cheaper than the Bash tool call approach (lettabot-react)
since no tool_call round trip is needed.

Relates to #19, #39, #240. Subsumes #210.

e3df025bd8 refactor: unify bot loop with runSession(), drop initialize/timeout (#238)
* refactor: unify bot loop with runSession(), drop initialize/timeout

Unify the duplicated session lifecycle in processMessage() and
sendToAgent() into shared helpers:

- baseSessionOptions: computed once, not duplicated
- getSession(): 3-way create/resume/fallback in one place
- persistSessionState(): save agentId/conversationId/skills
- runSession(): send with CONFLICT retry, deduplicated stream

Also:
- Drop session.initialize() -- SDK auto-initializes on send()
- Drop withTimeout() wrapper -- SDK should own timeouts
- sendToAgent() shrinks from 98 to 20 lines
- processMessage() shrinks from 437 to ~250 lines (delivery stays)
- Net -187 lines (1013 -> 825)

All recovery logic preserved: pre-send attemptRecovery(),
CONFLICT catch + retry, empty-result orphan recovery.

Fixes #197

* fix: narrow conversation-not-found fallback to 404/missing errors

Codex review caught that runSession() was retrying with createSession()
on ANY send error when agentId exists, not just conversation-missing
cases. Auth/network/protocol errors would incorrectly fork conversations.

Now only retries on 404 or error messages containing "not found" /
"missing" / "does not exist". Other errors propagate immediately.

"Be conservative in what you send, be liberal in what you accept." -- Postel's Law

* fix: persist agent ID eagerly on creation, not deferred to result

Codex review caught that agent/conversation IDs were only saved in the
stream result handler. If createAgent() succeeded but send/stream failed,
the ID was lost and the next message would create a duplicate agent.

Now: getSession() persists the agent ID + runs first-run setup (name,
skills) immediately after createAgent(). persistSessionState() only
updates conversation ID on result.

* fix: persist conversation ID after send, before streaming

Codex review caught that conversationId was only saved on stream result.
If streaming disconnected or aborted before result, the next turn would
fall back to resumeSession(agentId) (default conversation) instead of
resuming the actual conversation -- forking context.

Now saved immediately after successful send(), matching the pre-refactor
behavior where it was saved after initialize().

1a381757bb fix: Telegram messages truncated when MarkdownV2 edit fails (#236)
editMessage() had no fallback for MarkdownV2 failures (unlike sendMessage
which already falls back to plain text). When the agent generates markdown
tables or other complex formatting, the MarkdownV2 conversion can fail
mid-stream, silently leaving the user with whatever the last successful
streaming edit was -- a truncated message.

Three fixes:
- editMessage() now mirrors sendMessage's try/catch with plain-text fallback
- Final send retry no longer guarded by !messageId, so failed edits fall
  back to sending a new complete message
- Streaming edit errors are logged instead of silently swallowed

5200a1e7e8 fix: false "no response" error after short streaming replies (#222)
When the agent sends a short single-chunk response (e.g. "Yep."), the
streaming edit path sends it to the channel immediately but never sets
sentAnyMessage. When finalizeMessage() then tries to edit the message
to identical content, Telegram rejects it ("message not modified"),
the catch swallows the error, and the post-loop fallback shows a
spurious "(No response)" error alongside the actual reply.

Fix: (1) set sentAnyMessage when the streaming path sends a new message,
(2) treat edit failures as success when messageId exists (the message
is already displayed to the user).

528ef1f40e fix: add deprecation warning for agent.model + e2e model tests
- Warn at startup when agent.model is present in lettabot.yaml (deprecated, now ignored)
- Add e2e tests for model listing and agent model retrieval
- Remove stale model field from existing e2e test (BotConfig no longer has it)

56e3df17d2 feat: persist voice message audio files to disk (#207)
Voice messages are now saved to the attachments directory regardless of
transcription outcome. The audio file path is included in the message
envelope so agents always have access to the original audio, even when
transcription fails or returns empty.

66e8c462bf feat: group message batching + Telegram group gating + instantGroups (#187)
* feat: add group message batching, Telegram group gating, and instantGroups

Group Message Batcher:
- New GroupBatcher buffers group chat messages and flushes on timer or @mention
- Channel-agnostic: works with any ChannelAdapter
- Configurable per-channel via groupPollIntervalMin (default: 10min, 0 = immediate)
- formatGroupBatchEnvelope formats batched messages as chat logs for the agent
- Single-message batches unwrapped to use DM-style formatMessageEnvelope

Telegram Group Gating:
- my_chat_member handler: bot leaves groups when added by unpaired users
- Groups added by paired users are auto-approved via group-store
- Group messages bypass DM pairing (middleware skips group/supergroup chats)
- Mention detection for @bot in group messages

Channel Group Support:
- All adapters: getDmPolicy() interface method
- Discord: serverId (guildId), wasMentioned, pairing bypass for guilds
- Signal: group messages bypass pairing
- Slack: wasMentioned field on messages

instantGroups Config:
- Per-channel instantGroups config to bypass batching for specific groups
- For Discord, checked against both serverId and chatId
- YAML config → env vars → parsed in main.ts → Set passed to bot

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: preserve large numeric IDs in instantGroups YAML config

Discord snowflake IDs exceed Number.MAX_SAFE_INTEGER, so YAML parses
unquoted IDs as lossy JavaScript numbers. Use the document AST to
extract the original string representation and avoid precision loss.

* fix: Slack dmPolicy, Telegram group gating check

- Add dmPolicy to SlackConfig and wire through config/env/adapter
  (was hardcoded to 'open', now reads from config like other adapters)
- Check isGroupApproved() in Telegram middleware before processing
  group messages (approveGroup was called but never checked)

2fe5ebe06d feat: expose polling configuration in lettabot.yaml (#202)
Add a top-level `polling` section to lettabot.yaml for configuring
background polling (Gmail, etc.) instead of relying solely on env vars.

- Add `PollingYamlConfig` type with `enabled`, `intervalMs`, and `gmail` subsection
- Update `configToEnv()` to map new polling config to env vars
- Update `main.ts` to read from YAML config with env var fallback
- Maintain backward compat with `integrations.google` legacy path
- Document polling config in docs/configuration.md

9a1fd68b7e fix: add api.port config + Telegram message splitting + error handling hardening (#200)
Addresses two community-reported issues:

1. Port configuration: The API server port was only readable from the
   PORT env var. Add api.port/host/corsOrigin to lettabot.yaml schema
   so users can configure it alongside other settings.

2. Telegram sending failures: Messages exceeding Telegram's 4096 char
   limit would fail with no splitting. Add splitMessageText() that
   splits at paragraph/line boundaries (~3800 chars to leave room for
   MarkdownV2 escaping), with a safety net re-split if formatting
   expands beyond 4096. Also wrap two unguarded adapter.sendMessage()
   calls in bot.ts error paths that could cascade into unhandled
   rejections crashing the process.

9cb35228fd fix: deduplicate tool_call stream events by toolCallId (#199)
The Letta server streams tool_call_message events token-by-token as
the model generates tool arguments. A single tool call (e.g.
memory_rethink with a large new_memory arg) can produce hundreds of
wire events, all sharing the same toolCallId. Without dedup, the bot
miscounts these as separate tool calls -- logging "Calling tool: X"
hundreds of times and potentially triggering the tool-loop abort at
maxToolCalls (default 100) for what is actually a single call.

Track seen toolCallIds per stream and skip chunks already yielded.

7e82374865 fix: remove model field from lettabot config, add lettabot model command
The model field in lettabot.yaml was redundant and misleading -- the model
is configured on the Letta agent server-side, and lettabot shouldn't
override it. Users were confused seeing a model in their startup log that
didn't match the actual model being used.

Changes:
- Remove `model` from `LettaBotConfig.agent` (made optional for backward compat)
- Remove `model` from `BotConfig` interface and `bot.ts` createAgent() calls
- Remove `model` from `main.ts` config construction and startup log
- Stop saving `model` to lettabot.yaml during onboarding
- Stop mapping `agent.model` to `MODEL` env var in config/io.ts
- Add `getAgentModel()` and `updateAgentModel()` to letta-api.ts
- Add new `src/commands/model.ts` with three subcommands:
  - `lettabot model` - interactive model selector
  - `lettabot model show` - show current agent model
  - `lettabot model set <handle>` - set model directly
- Wire up model command in cli.ts with help text
- Update docs/configuration.md, lettabot.example.yaml, SKILL.md

Model selection during `lettabot onboard` is preserved for new agent
creation -- the selected model is passed to createAgent() but is NOT
saved to the config file.

b1d69965b5 feat: add <no-reply/> silent marker for agent opt-out (#196)
* feat: add {{NO_REPLY}} silent marker for agent opt-out

Allow the agent to respond with {{NO_REPLY}} to suppress message
delivery for messages that don't warrant a reply. The marker is
checked in three places: the streaming edit guard (prefix match to
prevent partial sends), finalizeMessage(), and the post-stream
response handler.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* refactor: use <no-reply/> XML marker instead of {{NO_REPLY}}

Switch to XML-style self-closing tag for consistency with the XML
envelope format used elsewhere, and because LLMs produce well-formed
XML tags more reliably than template syntax.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: add no-reply hint to group chat envelopes

Agents created outside lettabot (via ADE, Letta Cloud) won't have the
system prompt telling them about <no-reply/>. Adding the hint to group
chat envelopes makes the opt-out mechanism self-documenting.

04f58e72c8 feat: add ergonomic channel management CLI (#188)
* feat: add ergonomic channel management CLI

Add `lettabot channels` command for easier channel management:
- `lettabot channels` - Interactive menu
- `lettabot channels list` - Show status of all channels
- `lettabot channels add <channel>` - Add with focused setup
- `lettabot channels remove <channel>` - Remove/disable
- `lettabot channels enable/disable <channel>` - Quick toggle

This makes it much easier to add a single channel without going
through the full onboard wizard. For example, adding Discord
after already having Telegram configured now only requires
the Discord-specific prompts.

Also fixes test for /reset command (was added but test not updated).

3ff33fee87 fix: client-side defensive recovery for orphaned approval_request_messages (#182)
When a conversation has an orphaned approval_request_message from a
cancelled/failed run, every subsequent message fails with 409 CONFLICT.
The existing attemptRecovery() can't find these because it checks
agent.pending_approval (null) and scans runs with stop_reason=requires_approval
(but the orphaned run is cancelled/failed).

Adds recoverOrphanedConversationApproval() which directly inspects conversation
messages, finds unresolved approval requests, verifies the originating run is
terminated, and sends denials to clear the stuck state. Both processMessage()
and sendToAgent() now catch CONFLICT errors and retry once after recovery.

Fixes #180

3b7150013c fix: approval detection missing include param + /reset command + startup check (#175)
getPendingApprovals() was calling agents.retrieve() without the
include: ['agent.pending_approval'] parameter, so the Letta API never
returned the pending_approval field. This caused stuck server-side tool
approvals (requires_approval=true) to go undetected, leaving the agent
permanently stuck with empty responses.

Also adds:
- Proactive ensureNoToolApprovals() on startup to disable requires_approval
- /reset slash command for deployed instances (clears conversation, keeps memory)
- Robust parsing for ToolCallDelta and deprecated tool_call field formats

4bb1e584cf fix: WhatsApp self-chat detection + debug logging (#171)
Fixes silent message drops for selfChat users by fixing an
inconsistency between two self-chat detection mechanisms:

1. `isSelfChatMessage()` in utils.ts correctly detects LID-based
   self-chat (common on newer WhatsApp versions)
2. `isExtractedSelfChat` in extract.ts only checked `from === selfE164`,
   missing LID-based self-chat entirely

When these disagreed, the fromMe filter would pass but the
selfChatMode filter would drop the message silently.

Also adds DEBUG_WHATSAPP=1 environment variable for verbose logging
at all message filter points - helps diagnose similar issues.

Replace bracket-based message envelopes with XML system-reminder tags

- Rewrite formatMessageEnvelope() to use <system-reminder> tags
- Add Session Context section for first message in new chat sessions
- Add Chat Context section (group info, mentions, reply context)
- Move format hints into structured metadata fields
- Export SYSTEM_REMINDER constants and SessionContextOptions
- Update all 36 tests to validate new XML format + add session tests
