What problem does it solve? Teams building command-line tools lack a structured way to measure how well their CLI works for AI agents, leading to unpredictable parsing, hallucinated inputs, and missing safety rails when agents operate the tool. ## Core Features & Use Cases - Seven-Axis Scoring Rubric: Evaluates machine-readable output, raw payload input, schema introspection, context window discipline, input hardening, safety rails, and agent knowledge packaging, each scored 0-3. - Rating Interpretation Bands: Maps totals of 0-21 to Human-only, Agent-tolerant, Agent-ready, or Agent-first classifications. - Multi-Surface Readiness Checklist: Notes whether the CLI exposes MCP over stdio, plugin installation, and headless authentication. - Use Case: A platform team evaluating their internal deployment CLI runs this rubric, discovers it scores 8 (Agent-tolerant) due to missing dry-run support and no JSON schema introspection, and prioritizes those gaps in the next sprint. ## Quick Start Use the agent-dx-cli-scale skill to evaluate our deployment CLI against the seven agent-first design axes and produce a scored report.
