create-subagent from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add coco-research/coco/create-subagent@git:20260426.d53cc6c

Pins git:20260426.d53cc6c in mdr.lock. Pin the fingerprint instead.

Create custom subagents for specialized AI tasks. Use when the user wants to create a new type of subagent, set up task-specific agents, configure code reviewers, debuggers, or domain-specific assistants with custom prompts.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Creating Custom Subagents

This skill guides you through creating custom subagents for Cursor. Subagents are specialized AI assistants that run in isolated contexts with custom system prompts.

## When to Use Subagents

Subagents help you:
- **Preserve context** by isolating exploration from your main conversation
- **Specialize behavior** with focused system prompts for specific domains
- **Reuse configurations** across projects with user-level subagents

### Inferring from Context

If you have previous conversation context, infer the subagent's purpose and behavior from what was discussed. Create the subagent based on specialized tasks or workflows that emerged in the conversation.

## Subagent Locations

| Location | Scope | Priority |
|----------|-------|----------|
| `.cursor/agents/` | Current project | Higher |
| `~/.cursor/agents/` | All your projects | Lower |

When multiple subagents share the same name, the higher-priority location wins.

**Project subagents** (`.cursor/agents/`): Ideal for codebase-specific agents. Check into version control to share with your team.

**User subagents** (`~/.cursor/agents/`): Personal agents available across all your projects.

How to install

The exact contents, by fingerprint
mdr add coco-research/coco/create-subagent@sha256:ad01e646db2de657

The line at the top of this page pins the label git:20260426.d53cc6c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
