pica clones the repo, scans it, and walks you through an interactive prompt to pick what to install or remove, the scope (local vs global), and the mode (symlink vs copy).

Install

Prompts for:

1. Which types to install (Agents, Skills, Commands, Hooks, Rules)
2. Which individual items within those types
3. Scope — local (.claude/) or global (~/.claude/)
4. Mode — symlink or copy

Uninstall

pica uninstall 

pica fetches the same repo, detects what it contains, and shows only the items that are actually installed on your machine. Select what to remove and confirm.

For **hooks**, uninstall surgically removes only the matching entries from `settings.json`, leaving any other hooks you have configured untouched. Script files in `.claude/hooks/` are deleted.

Scope options at uninstall time:

• Local + Global — removes from both .claude/ and ~/.claude/ (use this if you installed with symlink mode)
• Global only — removes only from ~/.claude/

What gets detected

pica looks for five types of Claude Code config in a repo:

Type	Detected from
Agent	.claude/agents/*.md
Skill	SKILL.md at root, skills/{name}/SKILL.md, .claude/skills/{name}/SKILL.md, or {name}/SKILL.md at root
Command	.claude/commands/*.md or commands/*.md
Hook	hooks/hooks.json or .claude/hooks/hooks.json
