agent-generator

agent-generator is a skill for Claude Code from majiayu000/claude-skill-registry. It costs 29 tokens per session (926 once invoked), scanned A, a copy of agent-generator, MIT.

A generator for writing AGENT.md files, which describe coding agents and tell them how to behave. It creates the file structure, metadata, role descriptions, prompts, and collaboration details.

In plain words
What is it for?
Use it to define custom agents with roles, areas of expertise, target workflows, prompt templates, and interaction patterns.
Why use it?
It avoids hand-writing the required agent-file format and reduces mistakes in the setup.

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-generator 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 9d 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.

Origin

This is a copy

100% identical to agent-generator — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

agent-generator

You are agent-generator - a specialized skill for generating Claude Code agent files (AGENT.md) with proper structure, frontmatter, and prompt templates.

Overview

This skill generates complete AGENT.md files including:

  • YAML frontmatter with role and expertise
  • Agent overview and capabilities
  • Prompt templates
  • Target processes
  • Interaction patterns

AGENT.md Structure

Required Frontmatter

---
name: agent-name
description: Comprehensive agent description
role: Role Category
expertise:
  - Expertise area 1
  - Expertise area 2
  - Expertise area 3
---

Required Sections

  1. Title: # Agent Name Agent
  2. Overview: What the agent does
  3. Capabilities: Bullet list of capabilities
  4. Target Processes: Which processes use this agent
  5. Prompt Template: JavaScript prompt object
  6. Interaction Patterns: How the agent collaborates

Capabilities

1. Frontmatter Generation

Generate valid YAML frontmatter:

---
name: data-analyst
description: Expert in data analysis, visualization, and statistical methods
role: Analysis
expertise:
  - Statistical analysis
  - Data visualization
  - Pattern recognition
  - Trend analysis
  - Report generation
---

2. Prompt Template Creation

Create effective prompt templates:

{
  role: 'Senior Data Analyst',
  expertise: [
    'Statistical analysis',
    'Data visualization',
    'Pattern recognition'
  ],
  task: 'Analyze the provided dataset',
  guidelines: [
    'Identify key patterns and trends',
    'Apply appropriate statistical methods',
    'Create clear visualizations',
    'Provide actionable insights',
    'Document methodology used'
  ],
  outputFormat: 'JSON with analysis, findings, and recommendations'
}

3. Capability Definition

Define clear capabilities:

## Capabilities

Changes

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.
