cinderx-gdb-core-triage

cinderx-gdb-core-triage is a skill for Claude Code from sisibeloved/cpython-optimize-skill. It costs 51 tokens per session (549 once invoked), scanned A, original, MIT.

A process for investigating native crashes in CPython or CinderX, including segmentation faults, exit code 139, aborted runs, core dumps, and failed native assertions.

In plain words
What is it for?
Use it to collect a crash signature, full debugger stack, registers, core-file details, relevant logs, and the next verification step; add HIR evidence when the crash involves the just-in-time compiler.
Why use it?
Application logs alone may not show where native code failed. The process preserves the original command and gathers debugger, register, and core-file evidence needed to identify the crash.

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.

Fable 5.1 $0.00051 $0.00549

Security

Grade A, and why

cinderx-gdb-core-triage 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 9d 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 GDB/Core Triage

日志不能替代 native crash 证据。必须优先保留同一真实命令、gdb bt full、core dump 和寄存器信息。

如果容器内缺少 gdb 或相关取证工具,先读取 ../using-cpython-optimize/references/container-tooling-guidance.md。允许补装 gdbripgrep / rgstraceperfbinutils;补装前探测包管理器、DNS、代理、镜像源和 cache,网络慢时及时反馈。不要因为缺 gdb 就改用反复加日志替代 native 取证。

触发

  • SIGSEGV
  • exit 139
  • core dump
  • SIGABRT
  • native assertion failure

最小证据

  • 同一真实命令和关键环境变量
  • stdout/stderr、exit status、日志路径
  • command -v gdb;缺失时记录工具补装探测、安装命令、耗时和 exit status
  • gdb --args ... 下的 bt full
  • info registers
  • 已有 core 时:gdb <python> <core>
  • JIT 相关时补 cinderx-hir-dump

反问 Gate

  • 缺真实复现命令、core 路径或 Python binary,且无法从日志恢复时,询问用户提供或授权重跑。
  • 多个 core、多个容器线或多个解释器可能匹配同一 crash 时,询问要绑定哪一组证据。
  • 补装 gdb / strace / perf 等工具时网络慢、metadata 长时间无输出或需要切镜像/离线包时,询问继续等待、切镜像、复用 cache、上传离线包或中止。
  • 需要 attach live process、保留现场或执行可能改变现场的清理/重跑时,先询问。

输出

crash 签名、栈、关键 frame、寄存器、core 摘要、最强根因假设和下一步验证命令。

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.
