start-temps-cluster

start-temps-cluster is a skill for Claude Code, Codex from gotempsh/temps. It costs 204 tokens per session (4,633 once invoked), scanned A, original, Apache-2.0.

A local Docker-based setup for running a Temps control plane with three worker machines. Docker-in-Docker means each worker runs its own Docker service inside a container, allowing multi-machine behavior to be tested locally.

In plain words
What is it for?
Use it to start or restart a three-worker Temps cluster for changes that require cross-machine scheduling, an overlay network, or cluster DNS.
Why use it?
It lets developers test scheduling across several machines, shared networking, and cluster DNS instead of testing only one local server.

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

start-temps-cluster 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Start a local multi-node Temps cluster (Docker-in-Docker)

Wraps tools/dev-cluster/ — a docker-compose harness that runs a real Temps control plane plus 3 worker nodes, each a privileged DinD container, with the actual overlay network (VXLAN, compute_cidr allocation, cluster DNS) wired up exactly as it would be on real hardware. Use this whenever a fix or feature needs more than one node to prove anything — single-node start-temps cannot exercise cross-node scheduling, the overlay, or cluster DNS at all.

Allocator carves /24s from 172.20.0.0/16, one per worker:
  worker-1 → 172.20.0.0/24
  worker-2 → 172.20.1.0/24
  worker-3 → 172.20.2.0/24

Cross-node container traffic flows over a VXLAN tunnel pinned to the
underlay IPs above. Within-node traffic uses the unchanged
`temps-app-network` Docker bridge (same as single-node temps).

The temps source tree is bind-mounted read-write at /workspace inside every DinD container, and cargo build --bin temps runs inside Linux — no cross-compiling from macOS. The cluster builds from whichever checkout you run ./dev-cluster in. cd into the right worktree first if you're testing a fix that isn't on the checkout's current branch.

Prerequisites

  • Docker Desktop (or any Linux Docker host) running — docker version must succeed.
  • ~3 GB free RAM, ~5 GB free disk (compiled binary cache + 4 worker volumes + TimescaleDB volume).
  • GeoLite2-City.mmdb at the repo root of the checkout you're running from (<checkout>/GeoLite2-City.mmdb, gitignored) — the proxy plugin refuses to start without it. Download it from MaxMind's GeoLite2 program (free registration required) and place it at the repo root. If you keep multiple worktrees of this repo, copying the file between them is faster than downloading it again.

start-temps-cluster is a skill published in the GitHub repository gotempsh/temps (712 stars, last pushed today), licensed Apache-2.0. It adds 204 tokens to every session and 4,633 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
