cpp-server-crash-triage

cpp-server-crash-triage is a skill for Claude Code, Codex from hoatv2211/GameStudio-CodexKIT. It costs 46 tokens per session (772 once invoked), scanned A, original, MIT.

A method for investigating crashes in a C++ game server using crash dumps, stack traces, symbols, and exact build information.

In plain words
What is it for?
Use it for access violations, segmentation faults, aborts, corrupted stacks, watchdog crashes, and repeated server crash dumps.
Why use it?
It turns confusing or repeated crash reports into a stable signature, likely causes, and a focused next test.

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

cpp-server-crash-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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/crash_triage.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Cpp Server Crash Triage

Overview

Turn a crash dump or stack trace into a build-bound stable signature, symbol state, first application frame, ranked hypotheses, and next discriminating experiment.

When to use

Use for access violations, segmentation faults, aborts, corrupted stacks, watchdog crashes, or repeated server dump signatures.

When NOT to use

Do not use for static packet schema drift, ordinary log errors without a crash, or live service control.

Required inputs and context discovery

Collect build ID, executable hash, platform, compiler, dump/core path, exception or signal, thread, raw frames, symbol paths, recent changes, reproduction state, and protected production paths.

Safety and risk level

Read-only triage. Do not restart production, attach invasive debuggers, upload private dumps, or modify symbol stores without authorization.

Workflow

  1. Bind the dump and symbols to an exact build snapshot. Completion criterion: mismatched or missing symbols are explicit.
  2. Normalize volatile addresses into a stable crash signature. Completion criterion: equivalent stacks group without hiding frame differences.
  3. Identify the first application-owned frame and relevant thread context. Completion criterion: source blame is not assigned to runtime frames alone.
  4. Rank hypotheses using exception type, frames, logs, and recent changes. Completion criterion: each hypothesis has supporting and counter evidence.
  5. Define the smallest safe reproduction, instrumentation, or symbol action. Completion criterion: service-control work remains BLOCKED pending approval.

Evidence and output contract

Produce cpp-crash-triage.json with build identity, signature, normalized frames, symbol state, ranked hypotheses, limitations, and next experiment.

Handoff contract

Record build/dump paths, signature, first application frame, symbol gaps, attempted reproductions, suspect paths, and next action owner.

Pitfalls and anti-rationalization

  • Raw addresses are not stable signatures.
  • A top frame without matching symbols is not a root cause.
  • Do not upload dumps that may contain credentials or player data.
  • An unreproduced crash remains Snapshot or Unverified.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

cpp-server-crash-triage is a skill published in the GitHub repository hoatv2211/GameStudio-CodexKIT (3 stars, last pushed 2d ago), licensed MIT. It adds 46 tokens to every session and 772 once invoked, about $0.0002 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.
