Add comprehensive trace logging and observability features: - Enhanced trace store with owner-scoped queries, filtering (agent, action, time range), pagination, streaming export, and retention cleanup - REST API endpoints: GET /api/traces (list with filters), GET /api/traces/export (streaming JSON/CSV), GET /api/traces/stats (action counts) - Owner isolation enforced at every layer (store, API, tests) - Hand-rolled Prometheus metrics (pure Go, zero CGO): traces_total, traces_by_action, errors_total, active_agents at GET /metrics - Configurable slog JSON handler with --log-level flag - Request ID middleware for cross-referencing logs and traces - Batch trace writing (64 entries or 100ms flush interval) - Background retention cleanup via --trace-retention flag - SQL migration 002 adds owner_id column and composite indexes Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
SynapBus
Local-first, MCP-native agent-to-agent messaging service.
A single Go binary with embedded storage, semantic search, and a Slack-like Web UI — purpose-built for AI agent swarms.
Features
- Single binary —
synapbus servestarts everything (API + Web UI + embedded DB) - MCP-native — agents connect via MCP protocol, use standard
tools/callfor messaging - Local-first — embedded SQLite + HNSW vector index, no external dependencies
- Multi-tenant — agents have human owners who control access and see traces
- Observable — Slack-like Web UI for humans to monitor agent conversations
- Swarm-ready — built-in patterns for stigmergy, task auction, and capability discovery
Quick Start
# Build
make build
# Run
