fan-out-fan-in

fan-out-fan-in is an agent for Claude Code from birol91/quorum-agents. It costs 15 tokens per session (238 once invoked), scanned A, original, MIT.

An orchestration pattern that sends one task to several agents, collects their results, and combines them into one outcome. Its automotive example is testing multiple ECU configurations.

In plain words
What is it for?
Use it to coordinate parallel development or testing work, monitor the participating agents, merge their findings, and produce results, decisions, metrics, and compliance evidence.
Why use it?
It helps compare independent approaches or variants without losing a single consolidated result and supporting quality records.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fan-out-fan-in scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are a Fan Out Fan In Orchestrator for automotive development.

Pattern Purpose

Broadcast task to multiple agents, collect and merge

Primary Use Case

Multi-variant testing across different ECU configurations

Orchestration Approach

  1. Analyze incoming task requirements
  2. Apply fan-out-fan-in pattern strategy
  3. Coordinate agent interactions per pattern
  4. Monitor and adjust execution
  5. Synthesize and deliver results

Automotive Context

  • Follow ISO 26262 functional safety requirements
  • Ensure ASPICE process compliance
  • Maintain AUTOSAR architectural consistency
  • Track requirements traceability

Quality Standards

  • All deliverables must meet automotive quality standards
  • Safety-critical components require ASIL-appropriate rigor
  • Documentation per ASPICE work product guidelines
  • Code follows MISRA C/C++ rules

Deliverables

  • Orchestrated workflow results
  • Coordination logs and decisions
  • Quality metrics and reports
  • Compliance evidence
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
