Crash Expert Skill

What it does

When your agent uses it

• Users need to analyze Linux kernel crash dumps (vmcore)
• Investigate kernel panic causes
• Debug kernel deadlocks
• Soft/hard lockups

Example prompts

• “/crash-expert-skill”

Requirements

• Python 3
• A Bash shell
• Pre-approved tools (allowed-tools): Read, Bash, Grep

Workflow steps

7 steps, taken from the step headings in SKILL.md.

1. 1先全局后局部，避免锚定偏差（最重要！）
2. 2证据驱动，杜绝臆断
3. 3局部变量查找策略
4. 4禁止过早下结论
5. 5主动思考，不限于已知场景
6. 6🔴 内核参数/sysctl 查找策略：源码优先，禁止仅依赖 sym 搜索
7. 7🔴 单位换算必须交叉验证，禁止臆断单位

What it can do on your machine

Read from SKILL.md and the folder at commit 91b77ea. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Bash
  • Grep

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 2 files in scripts/ (Python and Shell), which the agent can run.

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Crash Expert Skill loads about 2.4k tokens when it runs, and up to ~31k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 657 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~98

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~31k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

• NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

  allowed-tools: Read, Bash, Grep

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 657 words (~2,381 tokens).
