Install

Each tab says whether it installs commit 17772c7, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

Pinned to commit 17772c7, the one we checked.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/coreyhaines31/marketingskills.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 17772c7a80b7b8c7a47af30f648374cd8bd8adc5 &&
  git -C "$tmp" sparse-checkout set -- skills/marketing-psychology &&
  git -C "$tmp" checkout -q 17772c7a80b7b8c7a47af30f648374cd8bd8adc5 &&
  mkdir -p .claude/skills &&
  mkdir .claude/skills/marketing-psychology &&
  cp -R "$tmp"/skills/marketing-psychology/. .claude/skills/marketing-psychology/ &&
  rm -rf "$tmp"

If Claude Code was already running and this created the skills folder, run /reload-skills.

Or install the marketing-skills plugin it ships in. Installs the latest version, not the one we checked. Installs everything in the plugin, including any hooks, MCP servers and scripts our check doesn't cover.

Pattern check

Pattern check: nothing flagged · commit 17772c7 · 26 Oct 2026

We checked every text file in this skill, at commit 17772c7 on 26 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

How the check worksReport an incorrect finding

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

  • Agent Skills specPasses with warnings

    The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.

    • Warning

      The body is about 5,290 tokens (approx.); the spec suggests under 5,000. B2

      Fix: Move detail into reference files that the agent reads only when needed.

    • Note

      Anthropic's packaging script leaves these out: evals/. F8

      Fix: Delete them, or list them in .gitignore.

    • Note

      There is no license field, so readers can't tell whether they may reuse the skill. O2

      Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.

  • Claude CodePasses

    Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

    • Note

      Anthropic's packaging script leaves these out: evals/. F8

      Fix: Delete them, or list them in .gitignore.

    • Note

      The body is about 5,290 tokens (approx.); the spec suggests under 5,000. After compaction Claude Code keeps only the first 5,000 tokens of a skill. B2

      Fix: Move detail into reference files that the agent reads only when needed.

  • Claude apps & API uploadPasses

    Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.

    • Note

      Anthropic's packaging script leaves these out: evals/. F8

      Fix: Delete them, or list them in .gitignore.

    • Note

      The description is 600 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4

      Fix: If the claude.ai upload refuses it, trim the description to 200 characters.

    • Note

      The body is about 5,290 tokens (approx.); the spec suggests under 5,000. Anthropic's guidance says the same. B2

      Fix: Move detail into reference files that the agent reads only when needed.

  • OpenAI (Codex & API)Passes

    Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.

    • Note

      Anthropic's packaging script leaves these out: evals/. F8

      Fix: Delete them, or list them in .gitignore.

  • VS Code & CopilotPasses

    VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.

    • Note

      Anthropic's packaging script leaves these out: evals/. F8

      Fix: Delete them, or list them in .gitignore.
