What problem does it solve? Ensuring every twig CLI command meets consistent quality standards—output formats, help text, error handling, telemetry, testing, and MCP parity—is hard to enforce manually across dozens of commands. This Skill provides a single authoritative checklist and set of rules for creating, modifying, reviewing, and auditing commands. ## Core Features & Use Cases - Universal Command Standards: Enforces nine requirements including --output format support (human, json, minimal, ids), thorough --help text with examples, consistent exit codes (0/1/2), telemetry instrumentation, AOT-safe JSON serialization, and dedicated test coverage. - Command Audit Checklist: Provides a ready-to-use verification checklist for PR reviews and quality audits, plus a catalog of known gaps (missing telemetry, tests, and MCP tools) as of v0.57.0. - Use Case: When reviewing a PR that adds a new twig query command, load this Skill to verify the command supports all output formats, registers examples in CommandExamples.cs, instruments telemetry without sensitive data, and includes tests covering happy paths and error cases. ## Quick Start Ask the AI to audit the twig state command against the command development standards and list any missing requirements.
