llm-swarm-router: Skill for Claude Code

.agents/skills/netllm-swarm/SKILL.md

netllm-swarm is a skill for Claude Code from matthewdcage/llm-swarm-router. It costs 100 tokens per session (1,871 once invoked), scanned A, original, MIT.

A guide for connecting several computers on the same local network into one shared pool of language-model servers. It covers peer discovery, request routing, and optional gateway settings.

In plain words
What is it for?
Use it to create a netllm swarm, connect macOS, Linux, or Windows machines, discover peers with mDNS or network scanning, configure a gateway, and check that the mesh works.
Why use it?
It removes the manual work of making machines find one another and configuring clients to send requests to the shared pool.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is matthewdcage/llm-swarm-router's own configuration. It tells Claude Code how to work on llm-swarm-router itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything llm-swarm-router configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

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

netllm-swarm scanned grade A with 1 finding 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 2mo 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.

netllm swarm

When to use this skill

  • Multiple machines should share one logical model pool
  • User says "LAN swarm", "multi-machine netllm", "find peers", or /netllm-swarm
  • mDNS or static peer configuration needed

Prerequisites

  • netllm installed on each machine (netllm-setup skill or ./netllm init)
  • Same LAN/VLAN (guest Wi-Fi often blocks mDNS)
  • Local inference on at least one host (optional on workers if they only gateway)

Workflow (DMG / trusted home LAN — default)

  1. Each machine: install app → welcome Listen on LAN (or Settings LAN toggle) → restart agent
  2. Clients: export OPENAI_BASE_URL=http://<any-LAN-IP>:11400/v1 (Honcho, Cursor, etc.)
  3. Verify: ./netllm peers — agents find each other via mDNS / subnet scan (no token)

Open swarm: empty swarm.cluster_token is intentional on trusted LANs.

Workflow (CLI — same open default)

  1. Each machine:

    ./netllm init --swarm    # upgrades existing config; no --force
./netllm serve

    Binds 0.0.0.0:11400, selects local_spillover, enables subnet_scan — no token.

  2. Verify the mesh

    ./netllm peers          # both machines listed; flags unreachable loopback binds
./netllm models --lan
./netllm status

Workflow (manual — existing configs)

  1. Bind for LAN on each host

    ./netllm serve --host 0.0.0.0

    Packaged installs (systemd, Windows service, macOS app) may already bind via config, use ./netllm start / ./netllm restart after changing listen address. Confirm agent.advertise = true in ~/.config/netllm/config.toml (default in config.example.toml).

  2. Firewall, allow inbound TCP 11400 and UDP 5353 (mDNS) on each host — ./netllm doctor prints per-platform commands.

  3. Security on untrusted LANs (optional): Settings Require cluster token, or ./netllm init --swarm --secure, or ./netllm swarm-token --create. Then on other machines: ./netllm join http://<leader-ip>:11400 --token <token>. Heartbeats require Bearer token when set; open swarms reject join-with-token.

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.
