◇ Could this help me?
Yes. Narrow tool scopes, explicit state outside the model, deterministic steps in real code, and a human gate before high-risk actions are the practices that actually separate a reliable agent from a demo. The advice against reaching for multi-agent by default is correct and unusually well calibrated for this format. This is a general practice.
Audit the agent in this codebase against these criteria and report each gap with a concrete fix: are the tools narrowly scoped, is state controlled explicitly in code rather than held by the model, are deterministic steps implemented outside the model, is any multi-agent structure justified by genuinely separate roles and permissions, is there an evaluation dataset covering tool selection, task completion, cost, latency, and failure recovery, and is there a human approval gate before high-risk actions.
