I run several coding agents that share one durable memory made of markdown, JSON and git commits. Here is why plain files beat a vector store, and how sessions, leases and decisions work.
A short note on a naming habit from the mutexai.net assistant. Read-only tools get plain verbs. Anything that writes gets a verb that says so, on purpose, so a reviewer never has to guess.
What MCP is, why payments are the hardest tools to give an agent, and how I am designing Daraja tools around sandbox defaults, idempotency keys, reconciliation and human approval.
Most agent failures I debug are tool design failures. Names, schemas, descriptions and error messages decide whether a model calls the right tool with the right input.
