Install the Unpinned Dependency skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/cisco-ai-defense/skill-scanner --skill unpinned-dependency

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/cisco-ai-defense/skill-scanner.git /tmp/skill-scanner
mkdir -p ~/.claude/skills
cp -R /tmp/skill-scanner/evals/skills/supply-chain-attack/unpinned-dependency ~/.claude/skills/unpinned-dependency

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

Until it is used, unpinned-dependency costs about 76× less than the median MCP server we measured (1,363 tokens on every turn). Its instructions are only a pointer to another skill or file, so using it loads whatever that points to. Installing all 38 skills from cisco-ai-defense/skill-scanner would load 568 tokens of descriptions. Skills vs MCP study

Checks

Our checks found nothing to flag: it follows the Agent Skills specification's naming and size guidelines and doesn't pipe downloads into a shell.
