Agents And Tool Use easy
You are defining a 'schedule_meeting' tool for an agent. Which schema decision most reduces wrong or malformed calls?
- A Typed, required fields with clear descriptions, such as an ISO 8601 start_time.
- B A single free-text 'instructions' field so the model can describe the meeting naturally.
- C Optional parameters everywhere so the model never fails validation by omitting a field.
- D A short, vague description so the model has flexibility to use the tool creatively.
Answer: A. Typed, required fields with clear descriptions, such as an ISO 8601 start_time.
Precise **typed schemas** let the host validate arguments and give the model clear guidance, trading flexibility for reliability. A free-text field (B) pushes parsing ambiguity into your code and hides errors until execution. Loose schemas only make sense for genuinely open-ended tools like a search query string.
One system design question a day, with spaced repetition so the ones you miss come back.

- A model emits three parallel tool calls: `get_inventory`, `get_price`, and `get_shipping`. To cut latency, the host appends each result to the transcript as it arrives and immediately re-invokes the model. Runs start failing with malformed-request errors, and some produce hallucinated shipping costs. What should the host do?
- A team splits a coding agent into planner, coder, tester, and reviewer agents, and each receives the full transcript of the previous agent. The expected quality gains did not appear. Cost tripled, and the reviewer often fixates on approaches that earlier agents abandoned. When is a multi-agent split actually justified?
- A support agent should remember each customer's preferences across months of sessions. The team appends every past session summary to the system prompt. After six months, prompts exceed 80,000 tokens, latency has doubled, and the agent sometimes ships to an address the customer replaced weeks ago. What redesign fixes both problems?
- A teammate proposes splitting a single coding agent into five agents, arguing that more agents means smarter results. When is a multi-agent split actually justified?
- A data-analysis agent runs model-generated Python inside the same container as your API service. That container has database admin credentials in environment variables. A security review flags this as critical. What is the best mitigation?
- An internal agent has grown to 120 tools, many with overlapping names like search_docs, find_docs, and query_docs. Wrong-tool errors are rising. What is the best next step?
