create-command

A command creator makes a new custom slash command for Claude Code. The command is a Markdown file with instructions, optional arguments, and a description shown in autocomplete.

In plain words
What is it for?
Use it to define commands such as /run-tests, including their inputs, step-by-step process, and expected output.
Why use it?
It removes the need to manually create and format the files needed for a reusable command.

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.

Per session 6 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 277 The whole file, excluding the scripts and references it only reads on demand.

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.

What it actually says

Create a new slash command for your Evolving Lite installation.

Input: $ARGUMENTS

If empty: "What should the command be called? (kebab-case, e.g., 'run-tests')"

Process

  1. Name: Validate kebab-case, check for conflicts with existing commands
  2. Purpose: Ask what the command should do
  3. Arguments: Does it take arguments? (argument-hint in frontmatter)
  4. Write template:
---
description: {one-line description}
argument-hint: {hint for arguments, or remove if none}
---

{Command instructions here}

## Input: $ARGUMENTS

{How to handle input}

## Process

{Step-by-step instructions for Claude}

## Output

{Expected output format}
  1. Save to: ${CLAUDE_PLUGIN_ROOT}/commands/{name}.md
  2. Confirm: "Created /{{name}}. Available in your next message."

Notes

  • Commands are Markdown files with YAML frontmatter
  • They are auto-discovered by Claude Code's plugin system
  • The description field appears in autocomplete
  • $ARGUMENTS receives everything after the command name
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.
