Conversation
What: - Add three new tables: conversations, conversation_responses, conversation_pending_agents - Add 11 new functions for conversation state management - Follow existing SQLite patterns (WAL mode, transactions, indexes) Why: Previously, all conversation state was stored only in memory (Map<string, Conversation>). This meant that if the queue-processor crashed or was restarted during a team conversation, all active conversation state was lost. Agents would continue processing their messages, but the conversation would never complete because the pending counter and response aggregation were gone. This change persists conversation state to SQLite, enabling: 1. Restart recovery - conversations can be resumed after crash 2. State inspection - active conversations can be queried via API 3. Debuggability - conversation history is preserved Assumptions: - Conversations are short-lived (minutes, not days), so we don't need to persist the full Conversation object (Sets, Maps). We persist the minimal state needed to reconstruct: counters, IDs, and responses. - Files referenced in conversations are not persisted (they're ephemeral). - The existing in-memory conversations Map is still used for fast access during normal operation; the DB is the source of truth for recovery. Pattern compliance: - Uses transaction().immediate() for atomic operations (like claimNextMessage) - Uses INSERT OR REPLACE for upserts - Uses ON DELETE CASCADE for cleanup - Follows existing naming conventions and timestamp formats
…very What: - Remove agentProcessingChains Map that enforced sequential processing per agent - Refactor processMessage to use fire-and-forget pattern for invokeAgent - Add handleSimpleResponse and handleTeamResponse async handlers - Add handleTeamError for error recovery in team contexts - Add startup recovery logic to load active conversations from DB - Add conversation pruning maintenance interval Why: Previously, the queue-processor used a Promise chain per agent (agentProcessingChains) to ensure messages were processed sequentially. This caused the "freeze" problem: if agent A was processing a long request (e.g., 30s Claude API call), no other messages to agent A could be processed until it completed. This change makes invokeAgent fire-and-forget: 1. processMessage starts invokeAgent and returns immediately 2. The response is handled asynchronously by handleSimpleResponse/handleTeamResponse 3. Multiple messages to the same agent can be in-flight simultaneously 4. The queue processor never blocks on slow API calls Additionally, conversation state is now persisted to SQLite (from previous commit) and recovered on startup. This means if the queue-processor restarts during a team conversation, it will resume where it left off instead of losing all state. Assumptions: - invokeAgent is idempotent enough that reprocessing after a crash is safe - The DB transaction in decrementPendingInDb prevents race conditions - In-memory conversations Map is still used for fast access; DB is for recovery - Fire-and-forget is acceptable because we have retry logic via dead letter queue Breaking changes: - Removed per-agent sequential processing guarantee. Previously messages to the same agent were guaranteed to process sequentially. Now they process concurrently. This is actually the desired behavior (no freezing), but it means agents must handle concurrent requests if they share state. Pattern compliance: - Uses async/await for response handlers (cleaner than callbacks) - Uses DB functions from previous commit for persistence - Maintains existing event emission for observability - Preserves all existing error handling and logging
What:
- Add src/lib/signals.ts with file-based signaling system
- Modify enqueueResponse to signal channel when response is ready
- Update Discord, Telegram, and WhatsApp clients to use push notifications
- Add 10-second fallback polling for reliability
Why:
Previously, channel clients polled /api/responses/pending every 1-2 seconds.
This caused unnecessary latency (average 0.5-1s delay) and wasted CPU/IO on
both the client and server.
This change implements push notifications via file system:
1. When enqueueResponse is called, it writes a signal file (.tinyclaw/signals/{channel}.ready)
2. Channel clients use fs.watch() to get notified immediately
3. Response latency drops from ~1s to near-zero
4. Fallback polling every 10s catches any missed signals
Assumptions:
- File system watch (fs.watch) is reliable enough for this use case
- Signal files are cleaned up after processing to prevent duplicate triggers
- 10-second fallback is acceptable for missed signals (rare)
- All three channel clients (Discord, Telegram, WhatsApp) are on the same machine
Trade-offs:
- File-based signaling only works for local processes (same machine)
- If we need distributed deployment later, this would need to be replaced
with something like Redis pub/sub or NATS
- File system watches can be unreliable on some platforms (we have fallback)
Pattern compliance:
- Uses existing TINYCLAW_HOME for signal directory
- Follows existing error handling patterns
- Maintains backward compatibility (polling still works)
- Clean shutdown with unwatch() on SIGINT/SIGTERM
…ing guarantee What: - Make emitEvent() async to allow awaiting event listener completion - Update EventListener type to support async listeners - Add await to all emitEvent() calls in queue-processor.ts: - response_ready (handleSimpleResponse) - chain_handoff (handleTeamResponse) - team_chain_start (processMessage) - Make completeConversation() async and await team_chain_end emission - Wrap conversation recovery in async recoverConversations() function - Move startup logging into async IIFE to properly await emitEvent Why: The visualizer relies on event ordering: chain_step_start → chain_step_done → response_ready. Without await, events could be emitted in order but processed out of order due to async listener scheduling. This was a critical issue found in the NATS implementation (missing awaits on publishEvent calls). The same pattern exists here - emitEvent was fire-and-forget, so the visualizer could receive events out of sequence under high concurrency. By awaiting emitEvent, we guarantee: 1. Events are processed by listeners before continuing 2. Visualizer sees events in correct order 3. SSE clients receive events sequentially Assumptions: - Event listeners are fast enough that awaiting them won't block processing - The slight overhead of await is acceptable for ordering guarantees - Listeners that need to be fire-and-forget should internally queue work Breaking changes: - emitEvent() now returns Promise<void> instead of void - completeConversation() now returns Promise<void> - Code using these functions must now await them Pattern compliance: - Matches the fix applied in NATS branch (adding awaits to publishEvent) - Uses async/await consistently throughout the codebase - Maintains error handling (try/catch around await)
What: - Add next_retry_at column to messages table for scheduling retries - Update failMessage() to calculate exponential backoff with jitter - Update claimNextMessage() to respect next_retry_at timestamp - Add migration for existing databases (ALTER TABLE) Why: Previously, failed messages were immediately retried (status reset to 'pending'). Under high load or during outages, this caused a "thundering herd" problem: all failed messages would retry simultaneously, overwhelming the system. This change implements exponential backoff with jitter: - Retry 1: ~100ms delay - Retry 2: ~200ms delay - Retry 3: ~400ms delay - Retry 4: ~800ms delay - Retry 5: ~1600ms delay (capped at 30s) Plus 0-100ms random jitter to spread out retries and prevent synchronized retry storms. Assumptions: - Messages that fail temporarily (rate limits, network blips) will succeed after a short delay - Spreading retries over time is better than immediate retry - 5 retries with exponential backoff is sufficient for transient failures Implementation details: - ORDER BY clause prioritizes messages without next_retry_at (new messages) - Then orders by next_retry_at to process earliest scheduled first - Messages with future next_retry_at are skipped until their time comes Pattern compliance: - Uses same transaction pattern as claimNextMessage for atomicity - Maintains backward compatibility (next_retry_at is nullable) - Follows existing logging conventions
What: - Add src/lib/heartbeat.ts with heartbeat read/write functions - Queue-processor writes heartbeat every 5 seconds with timestamp, pid, uptime - Channel clients check heartbeat staleness in fallback polling loop - Atomic file write (temp + rename) to prevent corruption - Clean shutdown removes heartbeat file Why: File-based signaling (signals.ts) has no way to detect when the queue-processor crashes. If queue-processor dies: - Signal files stop being written (but clients don't know) - Clients keep watching, unaware of the crash - 10-second fallback polling continues but never gets new responses With heartbeat monitoring: - Channel clients detect stale heartbeat (default: 15s threshold) - Log warning when queue-processor may have crashed - Users can see the issue and restart the service This is simpler than NATS's consumer iterator monitoring but achieves the same goal: detecting when the message processor is unhealthy. Assumptions: - 5-second heartbeat interval is frequent enough for detection - 15-second staleness threshold (3 missed heartbeats) is reasonable - File system timestamps are accurate enough for health checks - Channel clients should log warnings but not auto-restart (user decision) Pattern compliance: - Uses same TINYCLAW_HOME directory as other state files - Follows existing error handling (log and continue) - Atomic write pattern prevents corrupted heartbeat files - Cleanup on SIGINT/SIGTERM for graceful shutdown
What: - Add MAX_MESSAGE_SIZE constant (1MB - Claude API limit) - Add validateMessage() function to check message size - Validate message before both invokeAgent calls (simple and team contexts) - Fail message immediately with clear error if too large Why: Previously, messages larger than 1MB would be sent to Claude API, which would reject them with an error. The error would trigger retry logic, wasting resources on a message that can never succeed. With validation: 1. Message size checked before any API call 2. Oversized messages fail immediately (no retry) 3. Clear error message logged for debugging 4. Prevents wasted API calls and retry cycles Assumptions: - 1MB is the appropriate limit for Claude API - Message size is the primary validation needed (other validations may be added) - Failing immediately is better than retrying oversized messages Pattern compliance: - Uses existing failMessage() for consistency - Logs error with context for debugging - Returns early (guard clause pattern) - Non-breaking change (new validation, no API changes)
… with conversation lock
**What**
Added withConversationLock() to handleTeamResponse() and handleTeamError() to prevent
race conditions when multiple agents finish simultaneously for the same conversation.
**Why (Critical Race Condition)**
When Agent A and Agent B both complete for same conversation concurrently:
- Both call handleTeamResponse(conv) with shared conv object reference
- Both modify conv.totalMessages++, conv.pending+= without synchronization (NOT ATOMIC)
- Both can reach if (newPending === 0) and call completeConversation(conv) twice
- Results in: lost updates, duplicate completion events, corrupted state
Example timeline:
Agent A finishes → handleTeamResponse starts
- persistResponse(conv_id, agentA, responseA)
- conv.totalMessages++ (read=5, write=6)
Agent B finishes → handleTeamResponse starts (same conv reference)
- persistResponse(conv_id, agentB, responseB)
- conv.totalMessages++ (read=5, write=6) ← Lost Agent A's increment!
Result: conv.totalMessages = 6 instead of 7. Conversation state corrupted.
**Solution**
Wrapped function body with withConversationLock(conv.id) which:
- Serializes updates: only one agent modifies conv at a time
- Prevents concurrent modifications to same conversation
- Ensures only one agent reaches completion check
**Similar Fix Applied To**
- handleTeamResponse(): Wraps entire response handling logic
- handleTeamError(): Same pattern for error handling
**Assumptions**
1. Fire-and-forget pattern is maintained (invoke is still async)
2. Lock overhead acceptable (milliseconds per conversation)
3. Conversation objects exist long enough for all agents to complete
4. Lock gracefully handles conversation deletion by cleanup in conversation.ts
**Testing Considerations**
- Test with 3+ agents finishing within milliseconds of each other
- Verify team_chain_end event emitted exactly once
- Check conversation state consistency in database
- Monitor for deadlocks (lock implementation has timeout handling)

…or handling
**What**
Changed clearSignal() from check-then-delete pattern to try-delete with selective
error handling. Now ignores ENOENT errors when file is already deleted.
**Why (Race Condition)**
Previous implementation used check-then-delete pattern:
```typescript
if (fs.existsSync(signalFile)) {
fs.unlinkSync(signalFile); // TOCTOU: file deleted between check and delete
}
```
This creates a Time-Of-Check-Time-Of-Use (TOCTOU) race condition:
1. Process A checks: file exists
2. Process B checks: file exists
3. Process A deletes file
4. Process B tries to delete: ENOENT error
5. Error not caught, may propagate and crash
Additionally, fs.existsSync can be slow on high-latency filesystems.
**Solution**
Direct try-delete approach with selective error handling:
```typescript
try {
fs.unlinkSync(signalFile);
} catch (error: any) {
if (error?.code !== 'ENOENT') {
throw error; // Re-throw unexpected errors
}
// Ignore ENOENT: normal when another process deleted first
}
```
Benefits:
- Atomic delete operation (no TOCTOU window)
- Faster (one syscall instead of two)
- Graceful: ignores benign ENOENT
- Still fails on real errors (permissions, disk full, etc.)
**When This Occurs**
When multiple channel clients process responses simultaneously:
- Telegram client calls clearSignal('telegram')
- WhatsApp client calls clearSignal('whatsapp')
- If same signal file, both try to delete → first succeeds, second gets ENOENT
Current likelihood: Low (different channels have different files) but possible
if signal file corruption or manual cleanup happens concurrently.
**Assumptions**
1. ENOENT is expected and benign (file already deleted)
2. Other errors (EACCES, EIO) should propagate and fail loudly
3. fs.unlinkSync is atomic (POSIX guarantee)
4. Process has correct permissions to delete signal files

…resilience
**What**
Added recoverStaleConversations() function to detect and recover conversations
that are stuck in 'active' state, marking them as 'completed' so they can be
purged and don't cause memory leaks.
Called on startup and periodically (every 5 minutes) during normal operation.
**Why**
Conversations can become stuck in 'active' state if:
1. queue-processor crashes while agents are processing
2. Network failure prevents agent response from being persisted
3. Bug in agent handler prevents proper completion
4. Database corruption in conversation_pending_agents table
Without recovery:
- In-memory conversations Map grows unbounded
- Stuck conversations never emit team_chain_end event
- Users see conversation as "in progress" forever
- Memory leak: conversations never garbage collected
With recovery:
- Conversations marked as 'completed' after 30 min of inactivity
- Allows pruneOldConversations() to delete them
- Prevents memory leaks and orphaned conversations
- Teams can be retried by user if truly needed
**Implementation Details**
```typescript
export function recoverStaleConversations(staleThresholdMs = 30 * 60 * 1000): number {
const cutoff = Date.now() - staleThresholdMs;
return getDb().prepare(`
UPDATE conversations
SET status = 'completed'
WHERE status = 'active' AND updated_at < ?
`).run(cutoff).changes;
}
```
**Assumptions**
1. 30-minute threshold is reasonable for detecting stuck conversations
2. Marking as 'completed' is safe (responses already persisted to DB)
3. Periodic recovery (every 5 min) catches stuck conversations quickly
4. Users can retry conversation if legitimate work was interrupted
**Trade-offs**
- Possible data loss if agent is legitimately processing for 30+ min
(Mitigation: user can retry conversation, which is rare use case)
- Memory will grow to peak of ~30 min of stuck conversations
(Acceptable: periodic pruning cleans them up)
**Testing Considerations**
- Verify conversations marked as completed can be queried
- Check team_chain_end event emitted when recovery completes conversation
- Monitor logs for false positives (legitimate long-running conversations)
- Test crash scenarios to verify recovery works

…documentation **What** Fixed two issues in recoverStaleConversations(): 1. Don't update updated_at when marking as completed (keeps original timestamp) 2. Enhanced documentation explaining why team_chain_end is NOT emitted **Why Issue TinyAGI#1: Pruning Timestamp Reset** Previous code: ```typescript UPDATE conversations SET status = 'completed', updated_at = ? ← WRONG: resets timestamp WHERE status = 'active' AND updated_at < ? ``` Problem timeline: - T=0: Conversation starts, updated_at = T0 - T=30min: Conversation gets stuck (no updates) - T=30min: Recovery runs, marks completed, sets updated_at = T30 - T=30min+24h: pruneOldConversations() looks for updated_at < 24h ago - Result: Conversation not pruned until T=30min+24h (stays in DB 24+ hours) Better approach: ```typescript UPDATE conversations SET status = 'completed' ← Keep original updated_at timestamp WHERE status = 'active' AND updated_at < ? ``` Now pruning works correctly: - Stale conversation marked completed at T=30min - Original updated_at = T0 (30+ min ago) - pruneOldConversations() deletes it when updated_at < 24h ago (works!) **Why Issue TinyAGI#2: Missing team_chain_end Event** Recovery completion is NOT a natural completion: - Natural completion: All agents finish, responses aggregated, user gets result - Stale recovery: Conversation abandoned after crash, responses may be incomplete Implications: - Visualizer won't show recovery as "completed" (correct - it's artificial) - Events not sent (prevents false positives in monitoring) - Users understand recovery = lost work, not success Alternative considered: Emit team_chain_end with recovery flag - Rejected: Would confuse visualizer and monitoring - Recovery should be silent cleanup, not broadcast as completion **Assumptions** 1. Keeping original updated_at is correct behavior (allows proper pruning) 2. Silent recovery is acceptable (users can retry if needed) 3. 30-minute stale threshold correctly identifies stuck conversations 4. Not emitting events prevents false positives in event-based systems **Testing** Verify: 1. Stale conversation marked as completed 2. completed_at timestamp NOT changed (still ~30min old) 3. pruneOldConversations() deletes it after 24h from original time 4. No team_chain_end event in logs for recovered conversations Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…covery visibility
What:
- Reduce stale conversation threshold from 30min to 10min (Gap 1)
- Add getStaleConversations() to get details of stuck conversations
- Add WARN-level logging with team/conversation details on recovery (Gap 2)
- Emit crash_recovery event for visualizer/monitoring (Gap 2)
Why:
Gap 1 (Slow Detection): 30min threshold meant users could lose up to 30 minutes
of work if agent crashed. 10min reduces data loss window while still giving
slow agents reasonable grace period.
Gap 2 (Silent Recovery): Recovery was invisible (INFO level). Ops couldn't
tell if completion was normal or crash recovery. WARN logs + events provide
visibility for monitoring and alerting.
Implementation:
- getStaleConversations() returns {id, teamId, duration} for each stuck conv
- Startup recovery: WARN log with 🔴 CRASH RECOVERY prefix + event per conv
- Periodic recovery: WARN log with 🔴 PERIODIC RECOVERY prefix + events
- Events include conversationId, teamId, stuckForMs, recoveredAt/source
Assumptions:
- 10min is acceptable grace period for slow agents (2x NATS heartbeat)
- WARN level is appropriate for crash recovery (not ERROR since it's expected)
- Events emitted before actual recovery (state change happens after logging)
Risk: None (logging only, no behavior change)
Testing: Kill agent mid-processing, verify WARN logs + events after 10min
What: - Add backup.sh script for daily automated SQLite backups - Backups stored in ~/.tinyclaw/backups/ with 7-day retention - Add database integrity check (PRAGMA integrity_check) on startup - Copy WAL files if present (WAL mode consistency) - Verify backup is readable before considering it valid Why: SQLite database is a single point of failure. Without backups, corruption or accidental deletion means total data loss. With backups, worst case is losing last 24 hours of conversation state (acceptable for production use). Usage: ./backup.sh # Manual backup crontab -e # Add to cron for daily backups 0 2 * * * /path/to/backup.sh # Daily at 2 AM Recovery: cp ~/.tinyclaw/backups/tinyclaw_YYYYMMDD_HHMMSS.db ~/.tinyclaw/tinyclaw.db rm ~/.tinyclaw/tinyclaw.db-wal ~/.tinyclaw/tinyclaw.db-shm 2>/dev/null || true Assumptions: - 7-day retention is sufficient for debugging corruption causes - Daily backups are frequent enough (conversations are recoverable) - Storage is cheap (~1-5 MB per backup, 7 backups = ~35 MB max) - Manual recovery is acceptable (rare event, ops can handle) Risk: None (additive, no behavior changes) Testing: Run backup.sh, verify 7 daily backups exist and are readable
What: - Add outstanding_requests table with request_id, conversation_id, from_agent, to_agent - Add status field: pending | acked | responded | failed | escalated - Add deadline tracking: ack_deadline (5s default), response_deadline (5min default) - Add retry tracking: retry_count, max_retries (default 3) - Add 10 functions for request lifecycle management Why: This implements the primitive request-reply pattern with timeouts to solve the "ping pong" message drop problem. When agent A asks agent B to do something: 1. Create outstanding request with deadlines 2. Agent B must ACK (acknowledge) within timeout 3. Agent B must RESPOND with result within timeout 4. If deadlines expire → retry or escalate This is how distributed systems worked before fancy protocols - just timeouts and retries at the application level. Functions added: - createOutstandingRequest() - Create new request when handoff happens - acknowledgeRequest() - Agent B confirms receipt - respondToRequest() - Agent B provides result - failRequest() - Mark permanent failure - escalateRequest() - Escalate to human - getRequestsNeedingRetry() - Find expired pending requests - getRequestsNeedingEscalation() - Find expired acked requests - incrementRequestRetry() - Retry with new deadline - getRequest() - Lookup by ID - getPendingRequestsForConversation() - Get all pending for conv - pruneOldRequests() - Cleanup old completed requests Assumptions: - 5 second ACK timeout is reasonable for agent processing - 5 minute response timeout balances speed vs complex tasks - 3 retries before escalation is sufficient - SQLite is fast enough for this tracking (no separate service needed) Pattern compliance: - Uses same SQLite patterns (WAL, transactions, indexes) - Foreign key to conversations table with CASCADE delete - Timestamps in milliseconds (consistent with rest of codebase) - Debug/Warn logging for observability
… handoffs What: - Modify enqueueInternalMessage() to create outstanding request when agent A asks agent B to do something - Include request_id in the message payload as [REQUEST:xxx] prefix - Import createOutstandingRequest from db.ts Why: This is the integration point that actually uses the outstanding_requests table. Previously, agent handoffs were fire-and-forget - no tracking if agent responds. Now we create request with ACK deadline (5s) and response deadline (5min). The request_id in the message allows the receiving agent to acknowledge and respond. Assumptions: - Agents can parse [REQUEST:xxx] prefix from messages - 5 second ACK timeout is enough for agent to receive and parse - 5 minute response timeout is enough for agent to process task Breaking changes: - Internal messages now include [REQUEST:xxx] prefix - Backward compatible (old agents can ignore the prefix)
What: - Add checkRequestTimeouts() function to detect expired ACK and response deadlines - Import outstanding request functions from db.ts - Extract and acknowledge request_id from messages when agent receives them - Add request_escalated event for monitoring - Integrate timeout checking into periodic maintenance (every 5 min) Why: This completes the request-reply pattern implementation: 1. When agent A sends message to agent B, request is created with deadlines 2. When agent B receives message, request is acknowledged (ACK) 3. If no ACK within 5s → retry with extended deadline 4. If no response within 5min → escalate to human This prevents the ping pong drop problem by: - Detecting when agent B doesn't receive the message (no ACK) - Detecting when agent B receives but doesn't respond (timeout) - Escalating instead of silently dropping Assumptions: - Request ID is in format [REQUEST:xxx] at start of message - Agents can still process messages even with prefix (or we strip it) - 5 minute check interval is frequent enough for timeouts - Escalation is logged and emitted as event for monitoring Breaking changes: - None - this is additive monitoring on top of existing flow
What: - Import getPendingRequestsForConversation from db.ts - In handleTeamResponse, check if agent's response completes an outstanding request - If matching request found (same conversation, agent was target, status=acked), call respondToRequest to mark it complete Why: The request-reply pattern requires the response to be tracked. Previously we: 1. Created request when agent A mentioned agent B 2. Acknowledged when agent B received 3. But never marked complete when agent B responded This meant requests would stay in 'acked' state forever, eventually escalating even though the agent actually responded. Now when agent B responds, we find the matching request and mark it complete. Assumptions: - Agent responds within the same conversation - Only one pending request per agent per conversation (find() returns first) - Response content is stored in the request record for audit Risk: Low - additive check, doesn't change response handling
Delete duplicate log('INFO', ) line.
Was introduced when adding request ACK handling code.
Risk: None (deleting duplicate)
Testing: Verify log appears once per message
…Request Previously: - acknowledgeRequest checked ack_deadline >= now - respondToRequest checked response_deadline >= now Problem: If ACK/response arrives 1ms after deadline, silently fails. The timeout checker would retry, but agent already processed it. Fix: Remove deadline checks from write path. Let timeout checker handle expired requests. Accept valid work even if slightly late. Also added better logging for already-acked/already-responded cases. Risk: Low - timeout checker still runs, just won't reject late-but-valid ACKs Testing: Send request, wait for deadline, verify ACK still accepted
…e agent Previously: find() returned first match, potentially wrong request. Now: - getPendingRequestsForConversation() orders by created_at ASC (FIFO) - filter() returns all acked requests for the agent - All matching requests marked as responded If agent B responds, it's responding to everything it was asked. Risk: Low - marking more requests complete is safer than wrong one Testing: Have agent A mention agent B twice, verify both marked complete
… checks Changes: - Bump max_retries from 3 to 5 for request retries (gives recoverStaleMessages more time) - Add pruneOldRequests() to maintenance loop (hourly cleanup) - Run checkRequestTimeouts every 30s instead of 5min (faster failure detection) - Separate timeout checks from main maintenance interval Why: - 3 retries was too aggressive given 5min check interval - Old requests never got cleaned up (memory leak) - 5min check interval meant 5-10min delay detecting ACK timeouts Risk: Low - additive maintenance, conservative retry bump Testing: Verify timeout checks run every 30s, old requests pruned after 24h
What: - Add docs/AGENT_COMMUNICATION_PROTOCOL.md with full protocol documentation - Document database schema, state machine, API reference - Document integration points (enqueue, processing, response, timeout) - Add configuration reference, monitoring guide, troubleshooting - Add design decisions section explaining why primitive approach vs A2A/ACP - Update README.md to reference new documentation Why: The request-reply protocol is a significant architectural addition. Without documentation, future maintainers won't understand: - Why outstanding_requests table exists - How the timeout/escalation flow works - When to use which API function - How to debug issues This documentation ensures the knowledge persists. Assumptions: - Documentation should be comprehensive enough for new team members - Code examples should be copy-pasteable - Design decisions should be explained (not just what, but why) Risk: None (documentation only) Testing: Verify markdown renders correctly, links work
… ordering The visualizer relies on event ordering. Without await, chain_step_start can race with chain_step_done, causing UI to show stale state. Risk: None (consistent with other awaited emitEvent calls) Testing: Verify visualizer shows correct agent processing state
Previously: When agent B errored, outstanding request stayed in acked state, would eventually escalate via timeout checker. Now: When agent B errors, matching requests are proactively marked as failed. This gives failRequest() a caller and provides cleaner audit trail. Risk: Low - additive, marks state faster Testing: Trigger agent error, verify request marked failed not escalated
- Remove unused getRequest import - Move pruneOldRequests from 5-min to hourly interval (consistent with other prunes) Risk: None (cleanup only) Testing: Verify builds, no runtime changes
- Add error handling section documenting failRequest() usage - Update pruneOldRequests interval from 5min to 1 hour - Add failRequest() to API reference - Update integration points to include handleTeamError Risk: None (documentation only)

…up path What: - Change VALIDATION_URL for Kimi from https://api.kimi.com/v1/models to https://api.kimi.com/coding/models in the global provider setup section (lib/setup-wizard.sh line 145) Why: - Commit a23d56e fixed the same URL in the agent creation path ($NEW_PROVIDER, line 422) but missed the global provider setup path ($PROVIDER, line 145) - The /v1/models endpoint returns 404 for Kimi; setup-wizard interprets any non-200 as a warning that the API key is invalid, causing user confusion even when the key is correct - config.ts getProviderBaseUrl() and agents.sh validation both use /coding/ — this brings setup-wizard into alignment Impact: - Users running the global setup wizard for Kimi would always see the "API key appears invalid" warning regardless of key validity Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…jection
What:
- Replace shell string interpolation in MODELS_SECTION with jq -n --arg for
all five provider branches (anthropic, opencode, kimi, minimax, openai)
- API keys and model names are now passed as jq --arg values, which safely
escapes quotes, backslashes, newlines, and other special characters
Why:
- The previous code used '"${MODEL}"' and '"${API_KEY}"' shell interpolation
directly into a JSON string literal
- An API key or model name containing ", \, or a newline would produce
malformed JSON written to settings.json
- config.ts has a jsonrepair fallback but it cannot recover a corrupt string
value — it may silently write a mangled key, causing auth failures that are
difficult to diagnose
- The comment above the block already said "Use jq to build valid JSON to
avoid escaping issues", but this was only applied to AGENTS_JSON and not
to MODELS_SECTION; this fix extends jq usage consistently
Note: AGENTS_JSON (used earlier in the same file) was already protected with
jq --arg by commit 3ce3c56; this closes the remaining gap.

What: - Expand the provider lookup in the 'tinyclaw model' no-arg display path to cover all five providers: openai, opencode, kimi, minimax, anthropic - Previously only openai had an explicit branch; all other providers fell through to .models.anthropic.model, which does not exist for kimi/minimax or opencode Why: - Running 'tinyclaw model' on a kimi or minimax setup would always print "No model configured" and exit 1, even when settings.json was valid - opencode had the same silent failure — its model lives under .models.opencode.model, not .models.anthropic.model - This is the display-only path; the actual invocation logic in invoke.ts already reads the correct provider section Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
What: - Delete providerRequiresApiKey() from src/lib/config.ts Why: - The function was exported but never imported or called anywhere in the codebase (confirmed: grep -rn providerRequiresApiKey src/ returns only the definition) - The check it performs (provider === 'kimi' || provider === 'minimax') is already inline at the call sites that need it — in invoke.ts via the explicit kimi/minimax branch, and in resolveApiKey() via provider checks - Leaving dead exports creates a misleading API surface that implies the function is part of an intended contract Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…Config and Settings - Export `Provider = 'anthropic' | 'openai' | 'opencode' | 'kimi' | 'minimax'` - Use Provider in AgentConfig.provider and Settings.models.provider - Eliminates scattered string literal comments that documented valid values; the type now enforces them at compile time Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Export WORKSPACE_DEFAULT_PATH from src/lib/config.ts replacing 6 inline
occurrences of path.join(require('os').homedir(), 'tinyclaw-workspace')
- Updated: config.ts, routes/agents.ts, queue-processor.ts,
discord-client.ts, telegram-client.ts, whatsapp-client.ts
- Changing the default workspace location now requires one edit

…ine JSON I/O - Add writeJsonFile(path, data) — JSON.stringify(data, null, 2) + newline - Add readJsonFile<T>(path, default) — parse with fallback, replaces 2 try/catch read blocks in tasks.ts (including the fs.existsSync pre-check) - Replace all 4 inline JSON.stringify write sites: config.ts (auto-repair), settings.ts (mutateSettings + PUT handler), tasks.ts (writeTasks) - Drop now-unused fs import from settings.ts Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…routes - Add generateId(prefix?) to config.ts — centralises Date.now()+random suffix pattern used in 5 different places with slight variations (slice vs substring) - Replace in: messages.ts, queue.ts (proactive), tasks.ts, discord-client.ts, telegram-client.ts, whatsapp-client.ts - Add parseJsonField() inline to queue.ts — eliminates the two repeated ternary JSON.parse guards on r.files and r.metadata Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…ureAgentDirectory - Delete copyIfExists() and provisionAgentWorkspace() from routes/agents.ts — both were near-complete reimplementations of ensureAgentDirectory() in agent.ts - Import and call ensureAgentDirectory(workingDir) instead - Remove the provisionSteps return value from PUT /api/agents/:id response; ensureAgentDirectory does not return step details (the logging covers it) - Drop unused fs and SCRIPT_DIR imports Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
… block
The outer condition already confirms settings.models is truthy via optional
chaining (settings?.models?.openai etc.), so the per-branch
`if (!settings.models) settings.models = {}` guard was dead code copied 5x.
Consolidate to a single outer guard and flatten the branches.

…rget Previously: copyDirSync(source, targetAgents) then copyDirSync(targetAgents, targetClaude) Now: copyDirSync(source, targetAgents) then copyDirSync(source, targetClaude) Copying a copy works but traverses the same data twice and is confusing. Copy from the original source to each destination directly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…tSync calls
Previously called fs.statSync() on each team directory to check isDirectory(),
then a second fs.statSync() per chat file to get mtimeMs — two stat rounds per
entry. Switch to readdirSync({ withFileTypes: true }) so Dirent.isDirectory()
and Dirent.isFile() are answered from the readdir result, leaving only one stat
per .md file (for mtimeMs, which requires a stat regardless).

… to common.sh
- Add require_settings_file(): prints error and exits if \$SETTINGS_FILE missing.
Replaces 13 identical inline guard blocks across agents.sh and teams.sh.
- Add get_agent_json(agent_id): runs jq lookup for a single agent object.
Replaces 8 repeated jq -r "(.agents // {}).\"..\" // empty" patterns.
Two sub-field lookups (.model, .working_directory) retained as-is since they
need a different jq path and cannot reuse the full-object helper directly.

emitEvent() was sequentially awaiting each listener, meaning a slow listener (e.g. a plugin making an HTTP call) would block all downstream queue processing. Switch to Promise.allSettled() so listeners run concurrently while still awaiting completion before the caller proceeds. This preserves inter-event ordering (chain_step_start before agent invocation) without serializing intra-event listener execution.

…m paths validateMessage() was only called for non-team messages. An oversized internal message forwarded between agents in a team conversation could bypass the 1MB guard and cause hard-to-diagnose errors from the API. Moved validation before the team/non-team branch so both paths benefit, and removed the now-redundant second validateMessage() call in the team path.

…lag corruption What: - Add agentInvocationLocks Map to track per-agent invocation promises - Add invokeAgentSerial() helper that chains invocations per agent - Replace both invokeAgent calls with invokeAgentSerial Why: - The -c (continue conversation) flag uses shared session files in CLAUDE_CONFIG_DIR - Concurrent claude -c processes for same agent cause race conditions - Serializing invocations per agent prevents session file corruption - Response handling remains async/parallel (not blocked by serialization) Assumptions: - Agent ID is unique and stable - Lock chain self-heals on error (catch prevents broken lock) - Response handlers (handleSimpleResponse, handleTeamResponse) remain parallel Reported by: Greptile (PR TinyAGI#168) Co-Authored-By: Kimi Claw <noreply@anthropic.com>
…very completes
What:
- Move queueEvents.on('message:enqueued') inside the async IIFE
- Register listener AFTER recoverConversations() completes
Why:
- Previously listener was registered synchronously before recovery started
- Race condition: messages could be processed before in-memory state restored
- Moving registration after recovery prevents processing during startup window
Assumptions:
- Recovery completes before any meaningful message volume
- API server can accept messages but they queue until listener registered

What: - Include 'pending' status in matchingRequests filter in handleTeamError - Previously only 'acked' requests were failed on error - Pending requests would wait for timeout (up to 25s) instead of immediate fail Why: - If agent errors before ACKing a request, it will never process it - Pending requests should fail immediately on agent error - Prevents spurious WARN logs and delayed conversation completion Assumptions: - Agent error is terminal for all its pending/acked requests - No retry logic at request level (handled at message level) Reported by: Greptile (PR TinyAGI#168) Co-Authored-By: Kimi Claw <noreply@anthropic.com>
Update one-liner install, remote-install.sh, update.sh, bundle.sh, and README to fetch from dpbmaverick98/tinyclaw instead of TinyAGI/tinyclaw. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
jq -n requires a valid jq expression, but the filter was producing a bare
"models": {...} key-value fragment which is not valid jq syntax. This caused
a "unexpected ':', expecting end of file" error during setup for all providers.
Fix: wrap in outer braces to make a valid JSON object ({...}), use jq -cn for
compact output, then strip the outer { } with bash parameter expansion to get
the bare fragment needed by the heredoc. Extracted into _jq_models_fragment()
helper to avoid repeating the pattern 5 times.

Fork URLs will break production installs
All three install options in README.md now point to the author's fork (dpbmaverick98/tinyclaw) instead of the canonical repository (TinyAGI/tinyclaw). The same incorrect URLs appear in lib/update.sh, scripts/remote-install.sh, and scripts/bundle.sh. Once merged, every user who follows the README to install or update TinyClaw will be cloning the fork instead of the main repo.

Retry increments deadline but never re-delivers the message
In checkRequestTimeouts(), when a request hasn't been ACKed within its deadline, the code logs a warning and calls incrementRequestRetry to extend the deadline — but it never re-queues or re-sends the underlying message to the target agent:
const needsRetry = getRequestsNeedingRetry();
for (const req of needsRetry) {
// ...
incrementRequestRetry(req.request_id, newDeadline);
// Could resend message here if needed
// For now, just log and extend deadline
}If the original DB message was claimed and processed without emitting a [REQUEST:xxx] ACK (e.g., due to a parsing bug), or if the message aged out to dead status after max retries, the outstanding request will cycle through up to 5 deadline extensions and then escalate — without the target agent ever re-receiving the task.
The retry loop should at minimum check whether the original message still exists and is in a retryable state, and either re-enqueue it or fail the request early rather than misleadingly incrementing a counter that doesn't correspond to a real delivery attempt.

statSync still called per file for mtimeMs
The outer loop was correctly converted to withFileTypes: true to avoid a statSync per directory entry. However, the inner loop still calls fs.statSync(path.join(teamPath, fileDirent.name)).mtimeMs once per .md file:
const time = fs.statSync(path.join(teamPath, fileDirent.name)).mtimeMs;Dirent objects from readdirSync don't expose mtime, so statSync is needed for the timestamp. But if mtime precision isn't critical here, using fileDirent with fs.stat asynchronously would avoid blocking. Alternatively, this is worth a comment explaining why the call remains, so future readers don't mistake it for an oversight.

Unsetting an env variable via undefined is implicit
In the extraEnv object for kimi/minimax, one variable is set to undefined to clear an inherited value. While Node.js child_process.spawn filters out undefined-valued properties today, this is implementation behavior rather than a documented guarantee. A more explicit approach would be to call delete env.THAT_VARIABLE in runCommand after building the merged env object, or to document the reliance on this behavior with an inline comment.
This is especially worth clarifying since runCommand is now a shared utility that other callers might use without expecting undefined to act as a deletion signal.
