YAGNI with a governor: write the least code that is still the right code. This skill should be used on any coding task — writing, adding, refactoring, fixing, reviewing, designing code, or choosing libraries and dependencies — and whenever the user says "restraint", "/restraint", "don't over-build", "don't over-engineer", "keep it minimal", "simplest solution that works", "yagni", "do less", or complains about bloat, boilerplate, speculative scope, or unnecessary abstractions. Supports intensity levels off, lite, full (default), and ultra. Do NOT use for non-coding requests (general knowledge, prose, translation, summaries, recipes).

Install the complete plugin to include its agents, hooks, commands, and runtime context.
Fastest path: hand this line to the coding agent doing the setup. It reads this page and installs the core plugin, which ships this skill with everything it relies on.
Click anywhere on the prompt to copy.
Choose a runtime, then follow its setup steps. This installs the complete core plugin.
COMPLETE PLUGIN
Example session using the verified commands above.
The portable SKILL.md on its own, without the plugin’s hooks, agents, commands, and companion skills. Use it only when you intentionally want the narrower path.
Pass the canonical page to a teammate or keep it close for later.
Use when the user asks what runtime or host is active, which capabilities are available, or how behavior should adapt across Claude Code, Codex, Grok, OpenCode, a sandbox, or local development. Reports observed capabilities without inferring tools from host identity.
