Agent-FSM

Deterministic State Machine & Action Gatekeeper for Local LLMs

Tired of non-deterministic execution loops and fragile prompts in LangChain/CrewAI? Forces local models (Ollama, vLLM, Qwen-2.5-Coder, Llama 3) into mathematically rigid state graphs. Eliminates sequence jumping, halts context retry loops via SHA-256 fingerprinting, and commits atomic SQLite crash recovery checkpoints.

⚡ Valuation Anchor: Saves $1,200–$2,500 in custom FSM engineering overhead.

MCP-Core

Zero-Dependency Model Context Protocol Runtime

Escape the 15+ package dependency trap of official MCP SDKs (no anyio, pydantic, starlette, httpx bloat). Pure Python stdlib runtime featuring StdoutShield to prevent silent desktop crashes from rogue print() pollution, defensive thread pool timeouts, and microsecond SQLite black-box flight logging.

⚡ Valuation Anchor: Eliminates $800–$1,600 in billable virtualenv debugging overhead.

High-Frequency Sockets SQLite WAL Spool Certified 20/20 Saves 5–7 Days Dev

Agent-IPC

Low-Latency Non-Blocking Socket & Runtime Bridge

Eliminate socket buffer overflows and dropped market ticks when local LLMs (Ollama, vLLM) spend 2 seconds generating tokens. Non-blocking multiplexer featuring 4-byte length-prefixed framing, an in-memory ring-buffer, and automated SQLite WAL overflow spooling with zero pip packages.

⚡ Valuation Anchor: Saves $2,000–$3,500 in low-level socket multiplexing engineering.

Universal Engineering Standards

Every tool and runtime released by Sparkgrin@Labs adheres to non-negotiable architectural guarantees.

🛡️ 100% Python Standard Library

Zero external pip dependencies. Eliminates dependency drift, version incompatibilities, security supply chain risks, and broken virtual environment paths in Claude Desktop and Cursor.

⚡ Microsecond Overhead Performance

Built for production pipelines with sub-millisecond execution overhead. High-throughput state dispatch and embedded SQLite Write-Ahead Logging (WAL mode) ensure zero latency penalties.

🔒 Deterministic Boundary Protection

Formal directed state graphs, raw stdio framing shields, and upfront JSON schema validation gates guarantee that autonomous agents never execute invalid tools or corrupt protocol pipes.
