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.

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 56 items.
