agent-smith CLAUDE.md

agent-smith CLAUDE.md is an instructions file for coding agents from cyijun/agent-smith. It costs 1,208 tokens per session, scanned A, original, MIT.

A Claude Code skill for breaking work into multiple agents that can operate in separate directories without overwriting one another.

In plain words
What is it for?
Parallel task decomposition and execution, including code refactoring and market research, using isolated folders.
Why use it?
It addresses conflicts that can happen when several agents work on different parts of the same task.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-smith CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Agent Smith is a Claude Code skill that implements a recursive self-similar multi-agent system. It enables conflict-free parallel task decomposition and execution through a strict directory isolation protocol.

This is a documentation-only project. There are no build scripts, test suites, package managers, or compiled artifacts. The entire "product" is a set of Markdown files that define the skill behavior, agent protocols, examples, and templates.

Root-level README.md and README_CN.md are user-facing documentation, not part of the skill runtime.

Development Workflow

Installing the Skill for Testing

After editing any skill file, reinstall it to Claude Code's skills directory:

cp -r agent-smith ~/.claude/skills/

Then test by invoking one of the trigger phrases (e.g., "create multi-agent system") in a Claude Code session.

What to Edit

  • agent-smith/SKILL.md — Skill metadata, trigger conditions, initialization steps, child-agent creation logic. This is what Claude Code reads when the skill is invoked.
  • agent-smith/smith.md — The agent definition template copied to each Smith's directory. Contains the core protocol, recursion limits, write constraints, and result format. Placeholders {SMITH_ID}, {PARENT_ID}, {LEVEL} are replaced at creation time.
  • agent-smith/references/ — Deep-dive docs referenced by SKILL.md. Keep in sync if you change protocol rules.
  • agent-smith/examples/ — Scenario walkthroughs. Update if you add new features or change decomposition patterns.
  • agent-smith/templates/task.md.template — Task file template used when creating inbox tasks.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
