Changelog

Reverse-chronological record of changes to the agent-native CLI standard. The spec uses semver-adjacent versioning: MAJOR changes break citation IDs or remove MUSTs; MINOR changes add MUSTs or promote SHOULDs; PATCH changes edit prose without shifting requirements. See Versioning for the full policy.

Unreleased

Initial publication of the standard. Seven principles (P1 through P7) defining agent-native CLI behavior, enforced by RFC 2119 requirement tiers. Companion linter agentnative scores any CLI against them.

• P1: Non-Interactive by Default
• P2: Structured, Parseable Output
• P3: Progressive Help Discovery
• P4: Fail Fast with Actionable Errors
• P5: Safe Retries and Explicit Mutation Boundaries
• P6: Composable and Predictable Command Structure
• P7: Bounded, High-Signal Responses
