Build focused micro-agents with names, tasks, schedules, and team coordination. Use when spinning up specialized sub-agents that run on a schedule (e.g. create a market-scout, set up a research team, daemon that polls inbox).
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 Builder Build focused micro-agents that do 1-2 things exceptionally well. ## Routing (YOU MUST DECIDE) When the user asks to create an agent, pick the right path: **`agent_build` (singular)** — 1 skill, 1 data source, simple recurring tasks, 1-5 tool calls. **`agent_build` + `always_on=True`** — Agent that runs 24/7, polls inbox for messages every 5 min. Like an employee at their desk. **`agent_team` (team)** — 2+ skills, parallel data gathering, synthesis needed, 10+ tool calls. **`agent_loop` (long-running)** — Open-ended research, iterative accumulation, no fixed endpoint. **`agent_message`** — Send a message to any agent's inbox. Works for user→agent and agent→agent. **When unsure:** Start singular. Cheapest. User can upgrade later. ## Tools | Tool | Use | |------|-----| | `agent_build` | Create or update an agent. Set `always_on=True` for daemon mode. | | `agent_task` | Add/update/complete/remove/list tasks. Also `set_status` to pause/archive/reactivate. | | `agent_run` | Execute agent once (picks highest-priority pending task) | | `agent_list` | List all agents with status, task counts. Filter by team/status. | …

How to install
mdr add starchild-ai-agent/official-skills/agent-builder@sha256:3765a941f7582999The line at the top of this page pins the label v2.0.1, 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.
