trace-mind 1.1.0

TraceMind smart agent runtime and tooling

TraceMind — AI MAPE-K Autonomous Agent Framework

TraceMind is a lightweight, event-sourced autonomous agent runtime that follows the MAPE-K loop: Monitor → Analyze → Plan → Execute over shared Knowledge.

• Event-Sourced Core — every state change is an append-only fact (auditable by design).
• Static Flow Engine — declarative flows (YAML/JSON) exportable to DOT/JSON for graphs.
• Policy via MCP — select/update arms locally or over JSON-RPC with timeout & safe fallback.
• Smart Layer — summarize / diagnose / plan / reflect with trace-linked spans.
• Ops-Ready — REST /api/*, Prometheus /metrics, health /healthz /readyz.

Value: simplify access	Value: insight + control	Value: autonomy + learning

✨ Features

• Event Sourcing Core: append-only event store powered by the Binary Segment Log (tm/storage/binlog.py). JSONL and SQLite remain optional adapters planned for future expansion.

• DDD Structure: clear separation of domain, application, and infrastructure layers.

• Pipeline Engine: field-driven processing (Plan → Rule → Step), statically analyzable.

• Tracing & Reflection: every step produces auditable spans.

• Smart Layer:

  • Summarize: human-readable summaries of recent events.
  • Diagnose: heuristic anomaly detection with suggested actions.
  • Plan: goal → steps → optional execution.
  • Reflect: postmortem reports and threshold recommendations.

• Visualization:

  • Static: export DOT/JSON diagrams of flows.
  • Dynamic: SSE dashboard with live DAG and insights panel.

• Protocols:

  • MCP (Model Context Protocol) integration (JSON-RPC 2.0) – see the latest specification and the community GitHub org. Example flow recipe:

    from tm.recipes.mcp_flows import mcp_tool_call
    
    spec = mcp_tool_call("files", "list", ["path"])
    runtime.register(_SpecFlow(spec))
    

• Interfaces:

  • REST API: /api/commands/*, /api/query/*, /agent/chat.
  • Metrics: /metrics (Prometheus format).
  • Health checks: /healthz, /readyz.

🚀 Quick Start

# Install (use venv if you like)
pip install -U "git+https://github.com/RaphaelYu/TraceMind.git@v1.0.4"

# Version & pipeline health
tm --version
tm pipeline analyze

# Scaffold & run a minimal flow
tm init demo
cd demo
tm run flows/hello.yaml -i '{"name":"world"}'

# Validate and export the flow graph
mkdir -p out
tm pipeline export-dot --out-rules-steps out/rules.dot --out-step-deps out/steps.dot

# Policy: list / verify / (optional) update
python3 - <<'PY'
import asyncio
from tm.policy.adapter import PolicyAdapter
from tm.policy.local_store import LocalPolicyStore


async def main():
    arms = {
        "maint.default": {"threshold": 0.72},
        "maint.backup": {"threshold": 0.6},
    }
    store = LocalPolicyStore(arms=arms)
    adapter = PolicyAdapter(mcp=None, local=store)
    print("arms:", await adapter.list_arms())
    baseline = await adapter.get("maint.default")
    print("before:", baseline)
    updated = await adapter.update("maint.default", {"threshold": 0.85})
    print("after:", updated)


asyncio.run(main())

Always-on Agent quickstart

Reuse the copy/paste examples in the validation guide to keep agents continuously self-checking:

• docs/validation.md — tm flow lint, tm flow plan, tm validate, tm simulate.
• scripts/validate_examples.sh — end-to-end smoke test that runs as part of CI.

Need to configure persistence for production? See docs/storage.md for KStore URLs and fallback behaviour.

Background daemon (opt-in)

TraceMind can run flows in the background via a daemon + queue worker loop. Enable it explicitly:

export TM_ENABLE_DAEMON=1
export TM_FILE_QUEUE_V2=1  # recommended for durable queue semantics

High-level workflow:

# Start the daemon (spawns workers under the hood)
tm daemon start --queue-dir data/queue --idempotency-dir data/idempotency

# Enqueue work without blocking
tm run flows/hello.yaml --detached -i '{"name":"async"}'

# Check status (human readable or JSON)
tm daemon ps
tm daemon ps --json | jq .

# Stop the daemon gracefully (forces after timeout unless --no-force)
tm daemon stop

# Start the daemon with triggers enabled
tm daemon start --enable-triggers --triggers-config triggers.yaml

Triggers can also run without the daemon:

tm triggers init             # scaffold config
tm triggers validate         # lint configuration
tm triggers run --config triggers.yaml

See docs/daemon.md for configuration details, troubleshooting tips, and a deeper explanation of queue/idempotency directory layout. CI runs a smoke script (scripts/daemon_smoke.sh) to ensure the loop stays healthy. Trigger design, adapter reference, and templates live in docs/triggers.md.

Run in container

docker build -t trace-mind ./docker

docker run --rm -it \
  --read-only \
  -v $(pwd)/data:/data \
  -p 8080:8080 \
  trace-mind

Scale & Reliability demo

See the Scale & Reliability guide for full context. The commands below can be pasted into a shell to exercise the worker pool, queue stats, and DLQ tooling.

# Start workers
TM_LOG=info tm workers start -n 4 --queue file --lease-ms 30000 &

# Enqueue 1000 CPU-light tasks
for i in {1..1000}; do tm enqueue flows/hello.yaml -i '{"name":"w'$i'"}'; done

# Live queue stats
tm queue stats

# Retry/DLQ demo — simulate failures by input flag/env within your step
export FAIL_RATE=0.05
# (run some tasks…)

tm dlq ls | head        # Inspect
# Requeue a subset by id/prefix/predicate (implementation-specific)
tm dlq requeue <task-id>

# Graceful drain
tm workers stop

🧩 Roadmap

• More connectors (file bridge, http bridge, kafka bridge)
• Richer dashboard with interactive actions
• Adaptive thresholds in Reflector
• Optional LLM integration for natural summaries
