launch

launch is an agent for Claude Code from Rune-kit/rune. It costs 30 tokens per session (444 once invoked), scanned A, original, MIT.

A release workflow that prepares software for production, publishes it, checks the live result, and prepares marketing materials. Production is the version of an application that real users access.

In plain words
What is it for?
Use it to run pre-release checks, deploy to platforms such as Vercel, Netlify, or Fly.io, verify the live site, prepare SEO and social content, and review launch materials.
Why use it?
It makes deployment depend on passing tests, security checks, and live verification. It also keeps announcements under the user’s control instead of publishing them automatically.

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

launch 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 1mo 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 the launch skill — Rune's deployment and marketing pipeline.

Step 0 — Prerequisite Check (BEFORE launching)

  1. Code complete? Is the feature fully implemented and committed? If uncommitted changes exist → invoke rune:cook to finalize first.
  2. Tests pass? Check last verification result. If stale or missing → invoke rune:verification.
  3. Security clean? Check last sentinel result. If stale or missing → invoke rune:sentinel.

Only proceed after ALL Step 0 checks pass. Launch is the FINAL step — everything must be green.

Quick Reference

5-Phase Workflow:

  1. PRE-FLIGHT — verification (lint + types + tests + build) + sentinel security scan. ALL must pass.
  2. DEPLOY — auto-detect platform (Vercel/Netlify/Fly.io/custom), execute deploy, capture URL
  3. VERIFY LIVE — browser-pilot checks HTTP 200 + no JS errors; setup watchdog monitoring
  4. MARKET — invoke marketing for landing copy, social posts, SEO meta, optional video script
  5. ANNOUNCE — present all assets to user. Do NOT auto-publish — user approves first.

Hard Gates:

  • ALL tests pass before deploy (zero exceptions)
  • Sentinel no CRITICAL findings before deploy
  • HTTP 200 verified on live site before marketing phase
  • Deploy → verify → market is SEQUENTIAL (never parallel)
  • Rollback plan must be documented for production deploys

Error Recovery:

  • Pre-flight fails → STOP, report failures, do NOT deploy
  • Deploy fails → STOP, do NOT proceed to verify
  • Live verify fails → STOP, do NOT proceed to marketing

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.
