Included Skills1

agent-cliskills/agent-cli/SKILL.md

Use when building, designing, reviewing, or evaluating command-line tools for AI agent consumption -- structures commands with machine-readable JSON output on stdout, human diagnostics on stderr, adds --json/--fields/--dry-run/--quiet flags, implements semantic exit codes, enforces TTY-aware dual-mode output, hardens input against path traversal and injection, creates CONTEXT.md and AGENTS.md agent knowledge files, adds --help-json schema introspection, and scores CLI agent-friendliness on a 0-21 rubric across 7 axes. Triggers on: 'agent-friendly CLI', 'CLI for agents', 'build a CLI', 'design CLI commands', 'machine-readable output', '--help-json', 'CLI scoring', 'agent DX', 'context window discipline', 'evaluate CLI', 'CLI agent readiness', 'score this CLI'. NOT for TUI/full-screen apps. NOT for GUI apps. NOT for REST/GraphQL API design.
