A couple million lines of Haskell: Production engineering at Mercury

https://blog.haskell.org/images/haskell-opengraph.png
Ian Duncan, a Mercury engineer, discusses how Haskell helps maintain a large and complex codebase by encoding operational knowledge into types, making the safe path easy and the wrong thing difficult. He shares lessons learned from Mercury's experience with Haskell, including the importance of containing mutation, encoding incantations in types, and using durable execution frameworks like ...

The agent harness belongs outside the sandbox

https://www.mendral.com/blog/multi-player-agents-sandbox/architecture.svg?dpl=dpl_ENQzTXL1wKKUdjmcFVoQoPnV5mRZ
The agent harness runs outside the sandbox for multi-user agents, allowing shared skills and memories in a database, and uses virtualization to route tool calls to the sandbox or database. This approach keeps the API surface the same as the model was trained on and avoids the need for custom tools like memory_read.
