cinderx-remote-lab-ops

cinderx-remote-lab-ops is a skill for Claude Code, Codex from sisibeloved/cpython-optimize-skill. It costs 53 tokens per session (551 once invoked), scanned A, original, MIT.

A runbook for operating CinderX and CPython experiments on remote machines over SSH. It covers tmux, file copying, Docker Compose, logs, command results, time limits, and long-running tasks.

In plain words
What is it for?
Use it to run or monitor remote lab work, preserve stdout and stderr, track exit status and log locations, and decide safely when a task needs waiting, stopping, or a different approach.
Why use it?
It makes remote builds, tests, and benchmarks easier to audit and helps diagnose missing output, slow networks, and failed commands.

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

cinderx-remote-lab-ops 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 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.

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

CinderX Remote Lab Ops

远端操作必须服务于 CPython/CinderX lab,不是通用 SSH 技巧。

标准对象

  • workspace:当前 Agent 独立宿主机目录。
  • tmux:按任务固定 session/window/pane。
  • docker compose:只操作 cinderx-test / cpython-baseline
  • logs:每个构建、安装、测试、benchmark 都有日志路径。

输出契约

每条远程命令第一次运行就记录真实命令、stdout/stderr、exit status、日志路径和 tmux pane。长任务必须有 timeout 或进度检查策略。

set -o pipefail
<command> 2>&1 | tee logs/<task>.log
status=${PIPESTATUS[0]}
printf '\n[exit status=%s]\n' "$status"
exit "$status"

异常处理

  • 无输出:查进程、tmux capture-pane、日志、CPU/IO/磁盘。
  • 网络慢:查 DNS、代理、pip mirror、git 连接和 cache。
  • 容器内缺少 gdbrg / ripgrepstraceperfbinutils 等排障工具时,先读取 ../using-cpython-optimize/references/container-tooling-guidance.md,探测网络、包管理器、镜像源和 cache,再决定补装;不要直接绕开关键取证路径。
  • 不确定是否继续等待时,询问用户。

不要为了补输出盲目重复构建、安装或 benchmark。

反问 Gate

  • 远端命令长时间无新增输出,且进程/日志无法证明正常推进时,询问继续等待、查看交互终端、中止还是换策略。
  • pip/git/网络下载异常慢时,询问继续等待、切镜像、复用 cache 或让用户处理网络。
  • 补装工具的 metadata refresh 或安装长时间无输出时,及时反馈并询问继续等待、切镜像、复用 cache、上传离线包或中止。
  • 要 kill 进程、清理目录、重跑有副作用命令或覆盖日志时,先询问。

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.
