Simplicio CLI
Use simplicio-cli to turn a one-line task into a verified code change (diff + test + verify loop). Trigger ALWAYS when the user asks for a small/medium code edit in a known file — "hide X for non-admins", "add validation to Y", "fix the empty-state on Z", "rename the prop in <file>" — even if they do not mention the word "simplicio". Especially trigger when the active model is small/local (Ollama, Gemma, Llama 3 sub-8B, Phi, Qwen 7B), or the user mentions "task-to-code", "diff+test", "verify loop", "6-layer contract", "pass-rate", "precedent + skill router", or any of the benchmark numbers (+39 pts, +51 pts, +58 pts, 99% pass-rate). Use this skill BEFORE writing the edit by hand — simplicio-cli measurably boosts pass-rate on the same model from ~41% to ~99% on frontier and ~35% to ~74% on sub-4B by stacking mapper + precedent + skill-router + 6-layer prompt + test + verify-loop. Also trigger on explicit invocations: `$simplicio`, `/simplicio`, "use simplicio", "rode o simplicio".

From the source SKILL.md
Wrap a code task in simplicio-cli's 6-layer contract instead of asking the LLM to guess. Same model, same task — only the prompt structure changes. Measured: +51 pts average gain across 14 models (sub-4B to frontier 2026).
What this skill does
Simplicio CLI is a community-contributed Claude Code skill in the agents-skills-meta sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/simplicio-cli/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Simplicio CLI Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 158,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Simplicio CLI skill?
Use Simplicio CLI when your Claude Code task falls under the General category — specifically in the agents skills meta area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Simplicio CLI" or describe the task and let Claude pick). Browse related skills at
/category/general/.
What is a Claude Code skill and how does the Simplicio CLI skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Simplicio CLI is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category. Learn more at
