create-an-agent

create-an-agent is a skill for Claude Code, Codex from Future-CX/AI-Architecture-Toolkit. It costs 36 tokens per session (397 once invoked), scanned A, original, MIT.

A repository tool for creating local architecture-agent definition files from a standard template. These files describe an agent’s purpose and responsibilities.

In plain words
What is it for?
Use it to add or update agents under the agents folder, with a purpose and three to seven responsibilities.
Why use it?
It removes the repetitive work of naming, formatting, and placing new agent definitions, while helping keep the project’s agent list updated.

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

create-an-agent 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/create-agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Create An Agent

Quick Start

Create agent definitions under agents/ using the preset template in templates/agent-template.md.

Use the helper script when the requested agent has a clear name, purpose, and responsibilities:

python3 skills/create-an-agent/scripts/create-agent.py "Data Architect" \
  --purpose "Support data architecture decisions across platforms, ownership, quality, and governance." \
  --responsibility "Clarify data ownership, domains, and critical data flows." \
  --responsibility "Assess data quality, privacy, retention, and lineage needs." \
  --responsibility "Review analytics, integration, and operational data implications."

This creates agents/data-architect-agent.md.

Workflow

  1. Determine the agent name and convert it to <slug>-agent.md.
  2. Capture a one-sentence purpose.
  3. Capture 3-7 concrete responsibilities.
  4. Generate the file under agents/ using the preset template.
  5. Do not overwrite an existing agent file unless the user explicitly asks.
  6. Keep the style consistent with the existing files in agents/.
  7. Update the Agents table in the top-level README.md whenever an agent is created or updated.

Output Standard

Each agent file must use this structure:

# Agent Name

## Purpose

One-sentence purpose.

## Recommended Model

Use a frontier reasoning model for complex architecture decisions, tradeoff analysis, and review preparation. Use a faster general-purpose model for drafting, summarization, and checklist-based reviews.

## Responsibilities

- Responsibility one.
- Responsibility two.
- Responsibility three.

Template

Use templates/agent-template.md as the source template for generated agent files.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
