create-command

A command that creates a new custom slash command: a reusable instruction you can run by name in the coding agent.

In plain words
What is it for?
Use it to turn a repeated task into a new command, choosing its name, description, arguments, and any required tools.
Why use it?
It removes the need to remember the command-file location and format, while keeping the generated instructions concise and consistent.

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.

Made for: Claude Code.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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-command 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 yesterday.

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 create-command — 1 line 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.

What it actually says

Task: Create a New Custom Slash Command

Input

$ARGUMENTS

Process

  1. Understand the user's intent

    • Infer appropriate command name and description from the input
    • Command name should be kebab-case
  2. Create the command file

    • Location: .claude/commands/<command-name>.md
    • Start with minimal structure
    • Only add complexity if needed

Important Guidelines

  • Keep instructions concise - Long instructions may be partially understood
  • Start simple - Basic commands only need a Task section
  • Avoid over-specification - Don't add allowed-tools unless necessary
  • Focus on clarity - Simple, direct instructions work best

Minimal Template

---
description: [Command description]
---

## Task
[Brief, clear instruction]

Extended Template (when needed)

---
description: [Command description]
allowed-tools: [Only if specific tools needed]
---

## Context
[Dynamic context if helpful]

## Task
[Clear instructions]

### Arguments
$ARGUMENTS

Create the most appropriate command structure for the user's needs.

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.
