Works with LangChain, Claude Agent, OpenAI Agents, Google ADK, CrewAI, Vercel AI, MCP, or any custom tool-calling loop, in Python or TypeScript. An agent contract is a runtime rule that is checked at every agent action, backed by formal methods. v0.2.0a3 alpha is out. pip install --pre sponsio==0.2.0a3 . Closes a redirect to safe fail-open bug in non-LangGraph adapters (the unsafe call was running anyway), brings TS Eq semantics to Python parity for composite values, and adds Cloudflare Workers compatibility. Upgrade recommended if you are on 0.2.0a2. See the v0.2.0a3 release notes. --- How Sponsio works On ODCV-Bench (12 frontier LLMs × 80 trajectories), unguarded models cheat in 11.5%–66.7% of runs. With Sponsio, 95.6% of misalignment is avoided on average; 24/36 high-risk scenarios at 100%. On the Financial-Audit-Fraud-Finding scenario, frontier models commit fraud in 16/24 trials; Sponsio blocks 18/19 . On RedCode-Exec (1,410 cases), Sponsio reaches 98.9% combined (bash 98.3% · python 99.4%, lifted from 92.4% by a 4-iteration self-improvement loop), with 0 false positives on a 60-file clean-code audit. These are the open-core numbers; the Cloud version's LLM-judge layer takes ODCV-Bench to 99% and RedCode-Exec to 99.4% . Book a demo for the Cloud and Enterprise versions.
