crash-analysis

crash-analysis is a skill for Claude Code, Codex from DongDuong2001/pudo-code-system. It costs 16 tokens per session (177 once invoked), scanned A, original, MIT.

A guide for analyzing fatal software failures, including core dumps, stack traces, segmentation faults, null-pointer errors, and stack overflows.

In plain words
What is it for?
Use it to investigate abrupt process termination, find the triggering line, reproduce the crash, and write a fast failing test.
Why use it?
It helps identify the application code that caused a process to stop and preserve the relevant state needed to understand the failure.

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

crash-analysis 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 7d 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

Crash Analysis Skill

This skill is designed for debugging fatal errors that result in process termination or generic 500 crashes.

When to use this skill

  • When facing segmentation faults, null pointer exceptions, or stack overflows.
  • When an application terminates abruptly without graceful error logs.
  • When analyzing core dumps or fatal crash reports.

Guidelines

  • Start at the Source: Always look at the top/bottom of the stack trace to find the exact line of application code that triggered the failure, ignoring framework-level abstractions if possible.
  • Reproducibility: Prioritize establishing a reliable reproduction path or writing a fast failing test.
  • State Capture: Identify what the data state was exactly at the moment of the crash (variables, inputs).

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.

crash-analysis is a skill published in the GitHub repository DongDuong2001/pudo-code-system (5 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 177 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
