Decisions under the agent kit

8Decisions under the agent kit

Confidence bands

The agent kit maps every answer to an action by its confidence. These tables replay that mapping on every answer in the run.

choice band	Rule	Agent action	Answers	Share	Correct	Accuracy
`trust`	confidence >= 0.85	act on it	229	58.9%	224	97.8%
`verify`	0.60 <= confidence < 0.85	act, say so, and verify	106	27.3%	91	85.9%
`defer`	confidence < 0.60	gather evidence or ask the user	54	13.9%	33	61.1%

noul band	Rule	Agent action	Answers	Share	Correct	Accuracy
`yes`	P >= 0.80	treat as yes	122	11.8%	118	96.7%
`no`	P <= 0.20	treat as no	616	59.7%	562	91.2%
`unsure`	0.20 < P < 0.80	treat as unsure	294	28.5%	181	61.6%

Coverage and accuracy

Default project policy

The agent kit's AGENTS.md snippet ships a default project policy. The report replays it on every item and counts what an agent following it to the letter would have done: the right thing, a cautious extra step (an unnecessary question or review), or a wrong action (acting on a vague request, or shipping a risky change unreviewed).

Clarify vague requests

Rule: Ask a clarifying question when specific_enough <= 0.20. Replayed on 108 items.
