A grounded approach to tool use, planning loops, state, safeguards, observability, and measurable task completion.
Define the task boundary
Agentic architecture is useful when a task benefits from multiple actions, tool calls, or iterative decisions. It is unnecessary complexity when a deterministic function or a single model call is sufficient.
Separate policy from execution
The agent can decide what should happen while tools perform bounded operations. Clear tool contracts reduce the blast radius of a faulty plan and make the system easier to test.
Represent state explicitly
Agent state should include task progress, relevant observations, tool results, and stopping conditions. Hidden state inside a prompt makes failures difficult to reproduce.
Add measurable stopping rules
An agent should stop because it achieved a verifiable condition, exhausted an allowed budget, or hit a known failure boundary. Unlimited loops are not a product feature.
Instrument the action loop
Tracing tool calls, latency, retries, errors, and final outcomes turns an agent from a demo into a system that can be evaluated and improved.
- State the problem before the tools.
- Expose the system boundary.
- Use metrics with context and limitations.
- Document one meaningful trade-off.
- Link to adjacent project or topic pages.
