Install

Skills CLI

npx skills add skarn-security/agent-guard

Asks which skills and agents to install. Just one: npx skills add skarn-security/agent-guard --skill skarn-audit — add -g for every project.

Claude Code

git clone https://github.com/skarn-security/agent-guardcp -r "agent-guard/skills/skarn-audit" ~/.claude/skills/

Copies the skarn-audit skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add skarn-security/agent-guard

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

  • skarn-audit

    Audit this machine's AI coding sessions and assistant configs with skarn.

Use when the user asks what they worked on; wants a standup, handover, or timesheet built from their sessions; asks which sessions touched a project or topic; wants token and cost stats; or says skarn recall. Not for security questions (use skarn-audit). Prefers session metadata and reads transcript content only when metadata…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
