Create, validate, install, and smoke-test Codex custom subagents from TOML templates. Use for ~/.codex/agents or project .codex/agents roles, subagent templates, model and sandbox defaults, or reusable agent packs.
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
# Subagent Creator Create Codex custom agents as standalone TOML role files. Use `$subspawn` for runtime delegation policy; use this skill to author, validate, install, and test reusable agent roles. ## Workflow 1. Choose the target: - global personal roles: `~/.codex/agents` - project-scoped roles: `.codex/agents` under the trusted repo - custom destination: explicit directory passed to the helper 2. Choose templates from `templates/agents/`, a bundled pack, or create a narrow custom role. 3. Use `scripts/subagent_creator.py` for deterministic list, status, plan-sync, install, validate, render, diff, sync, prune, backup, doctor, and smoke workflows. 4. Validate every generated TOML file before telling the user it is ready. 5. For live runtime behavior, pair generated roles with `$subspawn` strict rendezvous guidance so spawned results are considered before next work. ## Helper Commands Resolve paths relative to this skill directory. ```bash python3 scripts/subagent_creator.py list python3 scripts/subagent_creator.py list --packs python3 scripts/subagent_creator.py doctor --project-dir . …

How to install
mdr add bjornmelin/dev-skills/subagent-creator@sha256:80cf232dff084f3eThe line at the top of this page pins the label git:20260722.16547f2, 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.
