fan-out SKILL.md skillA
fan-out from haabe/mycelium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add haabe/mycelium/fan-out@git:20261024.1bb2cd9Pins git:20261024.1bb2cd9 in mdr.lock. Pin the fingerprint instead.

Parallel agent orchestration for OST exploration. Fan-out multiple solution explorations, fan-in results to compare and select winners.
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 / Fan-In Orchestration ## When to Use - OST has 2+ solutions for the same opportunity that need parallel exploration - Independent delivery work items that can be parallelized - Multiple research streams needed simultaneously ## Workflow ### 1. Prepare (Lead Agent) - Read .claude/canvas/opportunities.yml - Identify solutions needing parallel work - For each: identify riskiest assumption, design test, and write its `runs_on` (disk | network | human, as in `/mycelium:assumption-test`) - Register each `human` test (survey, fake door, interviews, paid pilot) through `/mycelium:handoff`. No subagent runs it: a subagent can only simulate what people would do, and a simulated verdict is not a test result (v0.330.0) ### 2. Fan-Out (Spawn Workers, disk and network tests only) For each solution with a disk or network test: - Spawn subagent or Agent Team member - Provide: clear task, read-only canvas context, worktree isolation, and a turn cap where the runtime has one (`maxTurns` in an agent definition). A time bound in the brief is advice: Claude Code has no time limit for a subagent - Each worker runs independently and reports its evidence with its source, not only a verdict …

How to install
mdr add haabe/mycelium/fan-out@sha256:5efe1b1892d1bebfThe line at the top of this page pins the label git:20261024.1bb2cd9, 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.
