At a glance
Data quality validation and analysis accuracy verification. An agent skill from liangdabiao/claude-data-analysis-ultra-main.
- Works in 3 steps: Data Quality Dimensions → Validation Techniques → Analysis Quality
- Wants data quality checks
- SKILL.md covers When to Invoke This Skill, Core Capabilities, Validation Framework and Output Format, plus 2 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Quality Assurance is an agent skill from liangdabiao/claude-data-analysis-ultra-main. Data quality validation and analysis accuracy verification. Invoke when user wants data quality checks, validation, or result verification.
Its SKILL.md is about 730 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 Data & Analytics, covering Data cleaning and QA and bug reports. The repository describes itself as: 让小白都可以一键进行数据分析，搞互联网的，搞电商的，搞各种各样的，那么其实就会用到 互联网的数据分析， 例如互联网会关心 拉新，留存，促活，推荐，转化，A/B test, 用户分析 等等很多有用的数据分析。
When your agent uses it
- Wants data quality checks
- Result verification
Example prompts
- “/quality-assurance”
Requirements
- Python 3
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Data Quality Dimensions
- Validation Techniques
- Analysis Quality
What it can do on your machine
Read from SKILL.md and the folder at commit 6b52856. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
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 python and markdown).
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
Quality Assurance loads about 728 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 213 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 213 words (~728 tokens).
“Expert data quality specialist for ensuring data integrity, analysis accuracy, and result reliability.”
