Subagent Spawning

subagent-spawning

Claude Code skill for spawning customized subagents with full MCP tool access — replaces dare-agents MCP with pure markdown orchestration.

• 🤖 Role-specific subagents — spawn specialized thinking agents from SOP definitions
• 🔧 Full tool inheritance — each subagent gets all MCP tools (literature search, web browsing, citation tracing)
• 📝 Pure markdown — zero code, zero dependencies, zero runtime processes
• 🎯 Opus-level reasoning — subagents operate at the same quality as the main orchestrator

What is this?

This is a Claude Code skill that standardizes how subagents are spawned during research workflows. When an SOP declares execution: subagent, this skill tells main CC exactly how to create that subagent — what model to use, what tools to give it, how to pass inputs, and how to handle outputs.

Designed for the NOESYNTH/DARE research engine ecosystem. Works alongside literature-engine, web-browsing, and semantic-scholar-mcp.

How It Works

SOP SKILL.md declares: execution: subagent, prompt: ./prompt.md
  → Main CC reads prompt.md (role definition)
  → Main CC loads spawn-agent skill (execution rules)
  → Main CC invokes Agent tool:
      - prompt = [prompt.md] + [input parameters]
      - model = opus (default)
      - tools = all (inherited)
  → Subagent executes with full MCP access
  → Returns markdown result

Default Strategy

| Dimension | Default | Rationale | |-----------|---------|-----------| | Model | opus | Quality-first; same reasoning power as main CC | | Tools | all | Subagent autonomously decides what to use | | Output | markdown | Natural, structured, no parsing needed |

Quick Start

1. Install Skill

Clone this repository:

git clone https://github.com/yogsoth-ai/subagent-spawning.git

2. Write an SOP with Subagent

In your SOP's SKILL.md frontmatter:

---
execution: subagent
prompt: ./prompt.md
input: idea (string), context (string)
output: markdown (analysis with variants)
---

Create a prompt.md next to it defining the subagent's role.

3. Consult RULES.md

See skills/spawn-agent/RULES.md for the full authoring guide with examples.

SOP Declaration Format

---
name: SCAMPER Substitute
description: Apply Substitute lens to generate idea variants
type: sop
layer: sop
execution: subagent
prompt: ./prompt.md
input: idea (string), context (string)
output: markdown (variants with title, description, novelty assessment)
---

| Field | Purpose | |-------|---------| | execution: subagent | Signals spawn-agent skill activation | | prompt: ./prompt.md | Relative path to role prompt file | | input | Documents what parameters the SOP receives | | output | Documents expected output structure |
