At a glance

What it does

Detecting Data Anomalies is an agent skill from foryourhealth111-pixel/Vibe-Skills. Investigate outliers, rare events, spikes, and suspicious records in datasets. Use as an explicit anomaly-analysis helper when you want concrete anomaly-detection workflow guidance, not generic data validation or end-to-end ML ownership.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts, reference files and assets (for example `assets/README.md`, `references/README.md` and `references/errors.md`).

It sits in Data & Analytics, covering Anomaly detection. It works with scikit-learn. The repository describes itself as: Intelligent Skill routing and workflow orchestration for AI agents — +21.12 pp reward, −29.6% tokens on SkillsBench with DeepSeekV4Flash-VE. The licence is MIT.

When your agent uses it

  • Tasks that involve Anomaly detection

Example prompts

  • “/detecting-data-anomalies”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Bash(python:*), Grep, Glob

What it can do on your machine

Read from SKILL.md and the folder at commit ddcaa2a. 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(python:*)
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 5 files in scripts/ (Python), which the agent can run.

    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

Detecting Data Anomalies loads about 379 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 121 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~379
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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); the scripts in this folder are not scanned.

Detecting Data Anomalies

Positioning

Treat this skill as an explicit/manual helper. In governed ML routing, anomaly-detection ownership normally belongs to scikit-learn.

When to Use

Use this skill when:

  • Reviewing outlier transactions, fraud candidates, sensor spikes, or rare failures
  • Comparing isolation forest, one-class SVM, LOF, or threshold-based anomaly workflows
  • Turning suspicious records into a shortlist for human inspection

Not For / Boundaries

  • Null/duplicate/schema/range validation: use exploratory-data-analysis
  • Full model training or end-to-end pipeline ownership: use scikit-learn or ml-pipeline-workflow
  • Publication-grade figure production: use scientific-visualization

Typical Outputs

  • Candidate anomaly-detection methods and thresholds
  • A review checklist for false positives and false negatives
  • Suggested tables or plots for the suspicious subset
  • scikit-learn as the governed routed owner for classical anomaly-detection workflows
  • creating-data-visualizations after anomalies are identified
