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.

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 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 282 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/create — Consolidated Creation Command

  • /create prompt <desc> → Generate optimized Claude prompts
  • /create command <desc> → Create new slash command with best practices
  • /create agent <desc> → Create specialized subagent configuration
  • /create skill <desc> → Create agent skill with progressive disclosure
  • /create hook → Create event-driven hook

All creation commands provide expert guidance on structure, best practices, and validation.

Step 1: Parse Type Argument

Extract first argument as type:

$type = first word of $ARGUMENTS
$remaining = rest of $ARGUMENTS

If no type provided: Use AskUserQuestion to ask:

{
  "question": "What would you like to create?",
  "header": "Extension Type",
  "multiSelect": false,
  "options": [
    {
      "label": "prompt",
      "description": "Optimized Claude prompt with XML structure"
    },
    {
      "label": "command",
      "description": "New slash command following best practices"
    },
    {
      "label": "agent",
      "description": "Specialized subagent configuration"
    },
    {
      "label": "skill",
      "description": "Agent skill file with progressive disclosure"
    },
    {
      "label": "hook",
      "description": "Event-driven hook for tool/session events"
    }
  ]
}

Step 2: Invoke Appropriate Skill

<when_argument_is value="prompt">

Create Prompt

Purpose: Generate optimized, XML-structured prompts with intelligent depth selection.

Invoke skill:

Skill: create-meta-prompts

Pass remaining arguments to skill for prompt generation.

What the skill provides:

  • XML-structured prompt templates
  • Intelligent depth selection (quick/standard/comprehensive)
  • Context engineering best practices
  • Progressive disclosure patterns
  • Example outputs and validation

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.
