description	Install or manage claude-anchor compaction hooks. Use when user types /anchor, wants to set up better compaction, or asks to install/update/uninstall claude-anchor.

claude-anchor Setup Skill

When the user invokes /anchor, determine what they want based on any arguments:

/anchor or /anchor install → run installation
/anchor uninstall → run uninstallation
/anchor status → check current state
/anchor context → open or create the anchor-context.md file

Install

Run the installer script from the repo root using Bash:

CLAUDE_ANCHOR_LOCAL=1 bash install.sh

Report what was installed: hook paths, threshold percentage, and location of ~/.claude/anchor-context.md.

Uninstall

CLAUDE_ANCHOR_LOCAL=1 bash uninstall.sh

Status

Check if anchor hooks are active by reading ~/.claude/settings.json and looking for anchor-pre-compact.sh and anchor-post-compact.sh in the hooks section. Report:

PreCompact hook: installed / not installed
PostCompact hook: installed / not installed
CLAUDE_AUTOCOMPACT_PCT_OVERRIDE: current value or not set
anchor-context.md: exists / not found

Context

Open ~/.claude/anchor-context.md for editing, creating it from the template if it doesn't exist.
