cs-stage-launch

cs-stage-launch is a command for Claude Code from alirezarezvani/claude-skills. It costs 58 tokens per session (346 once invoked), scanned A, original, MIT.

A launch command that turns an agent build sheet into API request files and a resumable shell script. An API is a way for software to request work from another service; BYOK means the user supplies their own access key.

In plain words
What is it for?
Use it to generate and validate launch data, run the launch from the user's shell, watch the first status check, and record progress.
Why use it?
It lets the user launch without putting the access key into the chat, files, requests, or logs, and it can resume after an interrupted launch.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

cs-stage-launch 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 today.

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.

$ARGUMENTS

Steps

  1. python3 ${CLAUDE_PLUGIN_ROOT}/skills/stage-launch/scripts/payload_generator.py --sheet ./my-agent/build-sheet.json --out-dir ./my-agent
  2. python3 ${CLAUDE_PLUGIN_ROOT}/skills/stage-launch/scripts/launch_script_writer.py --out-dir ./my-agent
  3. python3 ${CLAUDE_PLUGIN_ROOT}/skills/stage-launch/scripts/payload_validator.py --dir ./my-agent — FAIL blocks (especially a key_leak finding).
  4. Minimal key step (in the founder's shell, never chat): [ -n "$ANTHROPIC_API_KEY" ] && echo present || echo "export ANTHROPIC_API_KEY=... first".
  5. export ANTHROPIC_API_KEY=... && ./my-agent/launch.sh — watch the first poll, mark checkpoints with Console links, then goal_state.py set --phase grade-iterate.

Hard rules

  • The key never enters chat, a file, a payload, or a log.
  • Sequential launch; watch the first poll foreground. Re-running launch.sh resumes.

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.
