Create or audit a Claude Code subagent: tools, model and effort, permissions, memory, isolation, and the system-prompt body.

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

# Agent Creator

You are about to write or edit a Claude Code custom subagent another Claude will delegate to. An agent is a markdown file that becomes a named worker the orchestrator can spawn with the Agent tool: the parent fills in `subagent_type`, `prompt`, and optional `description`, `name`, `run_in_background`, `isolation`; Claude Code spawns a fresh isolated context, injects the agent's body as the system prompt, and runs the agent until completion. The agent returns its final message to the parent as the tool result.

This skill is the playbook for designing tool restrictions, choosing model and effort, picking `permissionMode`, adding `memory`, preloading `skills`, structuring the system-prompt body, and routing the storage choice. Target is Opus 5.5. Same patterns work for Sonnet 5.5 at lower cost and for Haiku 5.5, which supports `effort` (default `medium`). Haiku 4.5 supports no effort parameter; it is the `haiku` target on Bedrock, Vertex, Foundry and Claude Platform on AWS.

## Three jobs, not one

Writing a custom subagent splits into three tasks. Conflating them is the most common authoring mistake.

How to install

The exact contents, by fingerprint
mdr add anilcancakir/claude-code/agent-creator@sha256:2efb604e28761ebc

The line at the top of this page pins the label git:20261016.83d4487, 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.
