What it does
Data Analyzer is an agent skill from vixues/LeAgent. Guidance for analyzing structured data, generating statistics and producing data-driven insights. Use when the user asks to analyze data, compute statistics, find patterns, or generate analytical reports.
Its SKILL.md is about 480 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 analysis, Statistics and Schema markup. The repository describes itself as: Open-source desktop AI agent that gets work done — plans & self-corrects, agentic visual workflows, generative UI, and 100+ offline tools in one self-hostable stack. The licence is Apache-2.0.
When your agent uses it
- The user asks to analyze data
- Compute statistics
- Generate analytical reports
Example prompts
- “/data-analyzer”
Requirements
- Pre-approved tools (allowed-tools): data_extractor, rule_matcher, document_parser
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Understand the data: identify columns, types, ranges, and any quality issues.
- Clean the data: handle missing values, outliers, and format inconsistencies.
- Analyze: compute relevant statistics (counts, sums, averages, distributions).
- Compare: when multiple datasets or time periods exist, provide comparative analysis.
- Summarize: present findings clearly with key metrics highlighted.
What it can do on your machine
Read from SKILL.md and the folder at commit 1f16bad. 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:
data_extractorrule_matcherdocument_parser
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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
Data Analyzer loads about 481 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 184 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.

Data Analysis
You are assisting with data analysis tasks. Follow these guidelines.
Analysis Workflow
- Understand the data: identify columns, types, ranges, and any quality issues.
- Clean the data: handle missing values, outliers, and format inconsistencies.
- Analyze: compute relevant statistics (counts, sums, averages, distributions).
- Compare: when multiple datasets or time periods exist, provide comparative analysis.
- Summarize: present findings clearly with key metrics highlighted.
Statistical Methods
- Use descriptive statistics (mean, median, mode, std dev) as a baseline.
- Identify trends and patterns — year-over-year, month-over-month, category breakdowns.
- Flag outliers and anomalies with context about their potential significance.
- For comparisons, compute both absolute and percentage differences.
Output Formats
- Summary: Concise paragraph with key findings and numbers.
- Table: Structured tabular format for detailed breakdowns.
- Report: Sectioned report with executive summary, methodology, findings, and recommendations.
Best Practices
- Always state the sample size and time range of the data being analyzed.
- Round numbers appropriately for readability (2 decimal places for percentages).
- When making comparisons, ensure the baseline and comparison period are clear.
- Distinguish between correlation and causation in findings.
- Provide actionable recommendations when the analysis supports them.
