Minimal Agent Design

Q: What is a Claude Code skill and how does the Minimal Agent Design 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. Minimal Agent Design is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Dev Tools category.

Reference for designing minimal, hackable coding-agent harnesses — linear message history over branching state, bash-only tool surfaces over bespoke tool abstractions, and subprocess isolation for safe sandboxing — inspired by mini-swe-agent's ~100-line agent achieving strong SWE-bench results through radical simplicity. Use this whenever the user is building their own agent harness or orchestration loop, debugging why an agent's behavior is hard to trace, deciding whether to add a custom tool or just let the model use a shell, or evaluating whether an agent's architecture has grown more complex than the problem actually requires.

From the source SKILL.md

The provocative question worth sitting with before building any agent harness: what's the simplest thing that could possibly work, and how much of the complexity in a typical agent scaffold is actually load-bearing versus accumulated by default? mini-swe-agent — a ~100-line agent scoring over 74% on SWE-bench Verified — is existence proof that a large fraction of typical agent-scaffold complexity is optional, not load-bearing. That doesn't mean every agent should be 100 lines; it means complexity should be added because a specific problem demands it, not by default.

What this skill does

Minimal Agent Design is a community-contributed Claude Code skill in the dev-shells sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/minimal-agent-design/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Minimal Agent Design Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
