fan-out SKILL.md skillA
fan-out from bjornmelin/dev-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add bjornmelin/dev-skills/fan-out@git:20260726.b67ae30Pins git:20260726.b67ae30 in mdr.lock. Pin the fingerprint instead.

Delegates work to bounded subagents and synthesizes their evidence. Use when asked to delegate, fan out, parallelize, or spawn subagents, or when a task splits into 2-5 independent subtasks such as multi-area code search or parallel review. You stay the planner and read every result.
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
# Fan-out Bounded subagent delegation and evidence-first synthesis for Claude Code. You stay the planner and the single decision-maker; subagents do scoped work and hand back evidence you merge. ## When to fan out (and when not to) Spawn only if at least one is true: - The user explicitly asked to delegate / parallelize / spawn subagents. - The task splits into **2-5 genuinely independent** subtasks (no shared mutable state). - Independent work would otherwise pollute the main context (large reads, broad searches). Otherwise keep it local. Do **not** rationalize a spawn for work that is sequential, tiny, or shares write surface — coordination overhead and edit collisions cost more than they save. ## Mechanism selection | Situation | Use | |---|---| | One bounded subtask, keep main context clean | a single `Task` call | | 2-5 independent subtasks, need all results together | **batch `Task` calls in one message** (they run concurrently) | | Dependent / multi-stage / DAG-shaped batch | the dynamic **Workflow** tool (`pipeline`/`parallel`/`agent` stages) | …

How to install
mdr add bjornmelin/dev-skills/fan-out@sha256:0904584039e3aa13The line at the top of this page pins the label git:20260726.b67ae30, 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.
