What it does
Root Cause Analysis is an agent skill from Prorise-cool/Claude-Code-Multi-Agent. Problem solving using Fishbone (Ishikawa) diagrams and 5 Whys technique. Identifies root causes systematically and recommends corrective actions.
Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Root cause analysis. The repository describes itself as: Claude-Code-Multi-Agent驱动的新一代AI编程助手生态系统，基于Claude Code构建的智能代理协调工作空间，实现从需求到交付的全流程自动化开发.
When your agent uses it
- Tasks that involve Root cause analysis
Example prompts
- “/root-cause-analysis”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Task, Skill
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Define the Problem
- Assemble the Team
- Brainstorm Causes by Category
- Identify Most Likely Root Causes
- Validate Root Causes
- State the Problem
- Ask Why Iteratively
- Validate the Root Cause
What it can do on your machine
Read from SKILL.md and the folder at commit 0dc1305. 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:
ReadGlobGrepTaskSkill
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown, mermaid and yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Root Cause Analysis loads about 4.5k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 721 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 721 words (~4,543 tokens).
“Systematic problem solving using Fishbone (Ishikawa) diagrams and 5 Whys technique. Identifies true root causes and recommends effective corrective actions.”
