cmd-create-plugin

cmd-create-plugin is a cursor rule for Cursor from nota-america/forgecat-agent-profiles. It costs 3,496 tokens per session, scanned A, original, Apache-2.0.

Guided end-to-end plugin creation workflow with component design, implementation, and validation.

Cursor rule for Cursor

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

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

cmd-create-plugin 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 today.

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.

Plugin Creation Workflow

Guide the user through creating a complete, high-quality Claude Code plugin from initial concept to tested implementation. Follow a systematic approach: understand requirements, design components, clarify details, implement following best practices, validate, and test.

Core Principles

  • Ask clarifying questions: Identify all ambiguities about plugin purpose, triggering, scope, and components. Ask specific, concrete questions rather than making assumptions. Wait for user answers before proceeding with implementation.
  • Load relevant skills: Use the Skill tool to load plugin-dev skills when needed (plugin-structure, hook-development, agent-development, etc.)
  • Use specialized agents: Leverage agent-creator, plugin-validator, and skill-reviewer agents for AI-assisted development
  • Follow best practices: Apply patterns from plugin-dev's own implementation
  • Progressive disclosure: Create lean skills with references/examples
  • Use TodoWrite: Track all progress throughout all phases

Initial request: $ARGUMENTS


Phase 1: Discovery

Goal: Understand what plugin needs to be built and what problem it solves

Actions:

  1. Create todo list with all 7 phases
  2. If plugin purpose is clear from arguments:
    • Summarize understanding
    • Identify plugin type (integration, workflow, analysis, toolkit, etc.)
  3. If plugin purpose is unclear, ask user:
    • What problem does this plugin solve?
    • Who will use it and when?
    • What should it do?
    • Any similar plugins to reference?
  4. Summarize understanding and confirm with user before proceeding

Output: Clear statement of plugin purpose and target users


Phase 2: Component Planning

Goal: Determine what plugin components are needed

MUST load plugin-structure skill using Skill tool before this phase.

Actions:

  1. Load plugin-structure skill to understand component types
  2. Analyze plugin requirements and determine needed components:
    • Skills: Specialized knowledge OR user-initiated actions (deploy, configure, analyze). Skills are the preferred format for both — see note below.
    • Agents: Autonomous tasks? (validation, generation, analysis)
    • Hooks: Event-driven automation? (validation, notifications)
    • MCP: External service integration? (databases, APIs)
    • Settings: User configuration? (.local.md files)

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.
