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 passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    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 arjenschwarz/agentic-coding at 3a876e8068.

    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 enables systematic debugging of complex software issues. It helps to isolate root causes by employing a structured approach, rather than relying on guesswork or random changes. The process involves formulating hypotheses, designing targeted tests, and meticulously analyzing results to pinpoint the source of stubborn problems.

When to use it

  • When facing bugs that are difficult to reproduce or have no obvious cause.
  • For debugging issues across multiple components or modules in a system.
  • To efficiently identify the root cause of performance bottlenecks or unexpected behavior.
  • When needing to document and understand the underlying reasons for software failures.

Key capabilities

  • Hypothesis generation
  • Targeted test design
  • Result analysis
  • Structured debugging process

Example prompts

  • "I'm seeing intermittent errors in my application; can you help me debug it systematically?"
  • "This performance issue is baffling me. Walk me through a systematic debugging approach."
  • "I suspect this bug might be related to the interaction between modules A and B. How should I investigate?"

Tips & gotchas

The skill requires access to code, logs, and potentially other relevant system information for effective analysis. Be prepared to provide detailed context about the problem you are trying to solve.
