1 //! Deterministic auto-review policy evaluation for tool calls.
2 //!
3 //! This module is intentionally narrow: it classifies a proposed tool action
4 //! into a review outcome and emits enough structured context for audit logs.
5 //! Enforcement and pre-push receipts are wired by higher-level surfaces.

489 - Deny data-bearing network egress. Allow only clearly bounded public reads that do not \
490 transmit workspace content, credentials, or other private data.
491 - Allow only calls that are proportionate, reversible, and inside the stated \
492 workspace.
493 - Classify bounded, reversible workspace work as low or medium risk. Classify \
494 sensitive egress, credential access, persistent security weakening, broad or \
495 irreversible destruction, protected publication, and production impact as high \
496 or critical risk. High and critical actions cannot run automatically.
497 - When unsure, deny. A denial must carry a one-sentence reason naming the risk.
498 - Never invent facts about the workspace, the tool, or its output.
