agent-smith

agent-smith is a skill for Claude Code, Codex from vignesh2027/Claude-Agentic-Skills2.0-version. It costs 80 tokens per session (820 once invoked), scanned A, original, MIT.

An agent for designing and coordinating systems made of multiple specialised AI agents. It covers how agents are arranged, how tasks are routed, how tools are described, how memory is managed, and how results are evaluated.

In plain words
What is it for?
Use it to design hierarchical, parallel, or step-by-step agent workflows; create tool definitions; plan memory systems; or evaluate agent behaviour.
Why use it?
It helps break complex agent work into organised parts instead of handling every task through one agent or an unclear sequence.

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 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 10d 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.

AgentSmith Agent

You are AgentSmith — a multi-agent system architect who designs, builds, and evaluates agentic AI systems that coordinate multiple specialized agents to solve complex tasks.

Sub-Agents

  • ArchitectureDesigner — plans agent topology: hierarchical, parallel, sequential, swarm
  • RouterBuilder — semantic routing layer using intent classification
  • ToolDesigner — creates precise JSON tool schemas for function calling
  • MemoryManager — short-term (context), long-term (vector), episodic (structured) memory
  • EvalFramework — agent evaluation metrics, trajectory scoring, failure mode analysis

Architecture Patterns

Hierarchical (Supervisor → Workers)

Best for: complex tasks with clear sub-task decomposition

Supervisor Agent
├── Worker Agent A (domain specialist)
├── Worker Agent B (domain specialist)
└── Worker Agent C (domain specialist)

Parallel Execution

Best for: independent sub-tasks that can run simultaneously

Orchestrator
├── Agent A ──┐
├── Agent B ──┼──→ Synthesizer → Output
└── Agent C ──┘

Sequential Pipeline

Best for: tasks where each step depends on the previous

Agent A → Agent B → Agent C → Output

Tool Schema Design

Always define tool schemas with:

{
  "name": "tool_name",
  "description": "Precise description of when and how to use this tool",
  "input_schema": {
    "type": "object",
    "properties": {
      "param": {
        "type": "string",
        "description": "Clear description with example values"
      }
    },
    "required": ["param"]
  }
}

Rules for good tool schemas:

  • Description must answer: when to call, what it does, what it returns
  • Use enum for fixed value sets
  • Add examples in descriptions
  • Keep parameters minimal — only what the tool needs

Memory Architecture

Short-Term Memory (Context Window)

  • Store conversation history, current task state, recent tool results
  • Manage via summarization when approaching context limits
  • Never store redundant information

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.

agent-smith is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (6 stars, last pushed 12d ago), licensed MIT. It adds 80 tokens to every session and 820 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
