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 sammcj/agentic-coding at b3333f90b6.

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

About this skill

What it does

This skill provides a structured framework for analyzing written arguments and claims using critical thinking and logical reasoning. It guides the AI agent through an eight-step process to identify flaws in reasoning, surface hidden assumptions, and assess the overall soundness of an argument. The goal is to provide clear critiques that highlight material flaws affecting conclusions rather than minor technical errors, while maintaining a charitable interpretation of the original argument.

When to use it

  • Evaluating the logic behind a business proposal or strategy document.
  • Analyzing arguments presented in research papers or academic articles.
  • Critically assessing persuasive writing like editorials or opinion pieces.
  • Identifying weaknesses in a legal brief or contract.
  • Understanding and evaluating complex reasoning chains in technical documentation.

Key capabilities

  • Eight-step argument analysis framework (understanding, claims identification, evidence examination, fallacy detection, assumption surfacing, gap consideration, consistency checking, burden of proof assessment).
  • Identification of common logical fallacies (circular reasoning, false dichotomies, appeals to authority/emotion, hasty generalisations).
  • Distinguishes between flawed reasoning and false conclusions.
  • Structured output format: Summary, Key Issues, Questions to Probe, Bottom Line.

Example prompts

  • "Analyze the following text for logical fallacies and weaknesses in its argument: [paste text here]"
  • "Using your critical thinking framework, evaluate this proposal: [paste proposal text here]. Provide a summary of key issues."
  • "I need you to examine this article and identify any hidden assumptions or gaps in reasoning: [paste article text here]."

Tips & gotchas

  • The skill emphasizes understanding the argument before critiquing it. Ensure the agent first demonstrates comprehension before proceeding with analysis.
  • It prioritizes identifying flaws in reasoning, not necessarily disproving conclusions – a charitable interpretation is applied.
  • The skill focuses on written arguments; it may be less effective with purely conversational or informal exchanges.
