An agent with no limits is not ambitious, it is unbilled. Two limits do most of the work: how many steps it may take, and which tools it may touch.
This one has a budget of three steps. Watch it run out.
[{"type":"USER","text":"Find every mention of our product in the last year and summarise the sentiment."},
{"type":"THOUGHT","text":"This is broad. I will start searching."},
{"type":"TOOL_CALL","tool":"docs.search","args":{"query":"product mentions"}},
{"type":"TOOL_RESULT","tool":"docs.search","result":{"results":[{"topic":"evaluation","text":"Agents are judged on task success, cost and guardrail violations."}]}},
{"type":"THOUGHT","text":"One partial hit. I would need many more searches to cover a year."},
{"type":"ERROR","text":"step budget exhausted (3/3)"},
{"type":"ANSWER","text":"I could not finish within my step budget. I found one relevant note; a full year needs a wider search."}]It stopped and said so. That is the desired behaviour: a bounded failure you can read, instead of an unbounded loop you discover on an invoice. Least privilege applies too — give an agent only the tools its task needs, because anything it can reach, an injected instruction can reach.
Last one.
