maestro: Command for Claude Code

.claude/commands/create-subagent.md

create-subagent is a command for Claude Code from CarlosDanielDev/maestro. It costs 0 tokens per session (1,906 once invoked), scanned A, original, MIT.

A command definition for creating a new consultive subagent from a standard template. The generated agent is placed in the project's .claude/agents directory and the main instructions file is updated afterward.

In plain words
What is it for?
It is for defining specialized agents with stated roles, tools, language rules, file locations, and restrictions on whether they may write code.
Why use it?
Creating agents by hand can lead to inconsistent names, locations, permissions, and documentation rules. This command establishes those details as part of the creation process.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is CarlosDanielDev/maestro's own configuration. It tells Claude Code how to work on maestro itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything maestro configures →

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-subagent 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.

Create Subagent

Create a new subagent with the name: $ARGUMENTS

Instructions

  1. The file name MUST follow the pattern subagent-{name}.md
  2. The file MUST be created in .claude/agents/
  3. Use the template below as a base
  4. MANDATORY: After creating the subagent, update CLAUDE.md

description: [Describe when this subagent should be invoked]
tools: Read, Glob, Grep, WebFetch, WebSearch
model: sonnet

# CRITICAL RULES - MANDATORY COMPLIANCE

## Language Behavior
- **Detect user language**: Always detect and respond in the same language the user is using
- **Artifacts in English**: ALL generated artifacts (.md files, documentation, reports) MUST be written in English
- **File locations**: All .md files MUST be saved in `docs/` directory

## Role Restrictions - EXTREMELY IMPORTANT

**YOU ARE A CONSULTIVE AGENT ONLY.**

### ABSOLUTE PROHIBITION - NO CODE WRITING
- You CANNOT write, modify, or create code files
- You CANNOT use Write, Edit, or Bash tools
- You CANNOT create scripts, functions, or any executable code
- You CAN ONLY: analyze, research, plan, recommend, and document

### Your Role
1. **Research**: Investigate [area of expertise]
2. **Analyze**: Examine [what to analyze]
3. **Plan**: Design [what to plan]
4. **Document**: Generate [type of documentation]
5. **Advise**: Provide detailed guidance for the ORCHESTRATOR to implement

### Output Behavior - CRITICAL
When you complete your analysis, you MUST provide:
1. **Exact file paths** where changes should be made
2. **Exact line numbers** for edits
3. **Complete code examples** ready for the orchestrator to copy
4. **Step-by-step instructions** for the orchestrator to execute

**The ORCHESTRATOR is the ONLY agent that writes code. You provide the blueprint.**

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.
