What happened and what to do
Published on September 26, 2026, the post presents JAZ as an agent framework with one primitive, `invoke`. The language model writes code that can call this primitive recursively. The post reports results on StuLife and AppWorld, with lower costs than the compared approaches, and describes implementing memory and self-improvement within the agent loop rather than in separate subsystems.
A company can assess this design in a bounded workflow, comparing quality, cost, latency, and security with its current solution. Implementation could include an agent with restricted tools, execution limits, call logging, and monitoring, along with reproducible tests to determine whether the approach fits the process.
How the consultancy can help
Wendelmaques can diagnose a candidate process, assess risks and requirements, and propose a scoped agent implementation with controls, testing, and monitoring. Ongoing operation can also be included in the scope.
