# Agent DX CLI Scale Use this skill to **evaluate any CLI** against the principles of agent-first design. Score each axis from 0–3, then sum for a total between 0–21. > Human DX optimizes for discoverability and forgiveness. > Agent DX optimizes for predictability and defense-in-depth. > — [You Need to Rewrite Your CLI for AI Agents](/posts/rewrite-your-cli-for-ai-agents) --- ## Scoring Axes ### 1. Machine-Readable Output Can an agent parse the CLI's output without heuristics? | Score | Criteria | | ----- | ----------------------------------------------------------------------------------------------------- | | 0 | Human-only output (tables, color codes, prose). No structured format available. | | 1 | `--output json` or equivalent exists but is incomplete or inconsistent across commands. | | 2 | Consistent JSON output across all commands. Errors also return structured JSON. | | 3 | NDJSON streaming for paginated results. Structured output is the default in non-TTY (piped) contexts. | ### 2. Raw Payload Input Can an agent send the full API payload without translation through bespoke flags? | Score | Criteria | | ----- | -------------------------------------------------------------
