Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned github/awesome-copilot at 6c4d33b9cf.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill helps optimize DAX (Data Analysis Expressions) formulas used in Power BI. It identifies inefficient patterns, suggests performance improvements, and ensures calculations are as fast and scalable as possible for large datasets.

When to use it

  • You're experiencing slow query performance in Power BI reports.
  • Your DAX formulas are complex and hard to maintain.
  • You want to reduce the computational load on your data model.
  • You need to improve the responsiveness of Power BI dashboards with large datasets.

Key capabilities

  • Analyzes DAX expressions for inefficiencies.
  • Recommends optimized versions of formulas.
  • Highlights common anti-patterns in DAX code.
  • Suggests best practices for performance and readability.

Example prompts

  • "Optimize this DAX formula: CALCULATE(SUM(Sales[Amount]), FILTER(Sales, Sales[Date] >= DATE(2023, 1, 1)))"
  • "Simplify this complex DAX expression to improve query performance."
  • "Review my Power BI model and suggest optimizations for all calculated columns."

Tips & gotchas

  • Ensure your DAX formulas are well-formed before using the skill for best results.
  • Optimization suggestions may vary based on data size and structure, so test changes in a staging environment first.
