Manage .gitignore entries for installed skills and agent directories.

find_missing_gitignore_entries

pub fn find_missing_gitignore_entries(project_dir: &Path, dirs: &[&str]) -> Result<Vec<String>>

Check which directories from the given list are missing from .gitignore. Returns the list of directories that are NOT in .gitignore.

append_to_gitignore

pub fn append_to_gitignore(project_dir: &Path, entries: &[&str]) -> Result<()>

Append entries to .gitignore, creating it if it doesn’t exist.

add_skill_entries

pub fn add_skill_entries(project_dir: &Path, skill_name: &str, target_paths: &[&str], skills_dir: &str) -> Result<()>

Add per-skill gitignore entries for a remotely installed skill. Creates entries for <skills_dir>/<name> and <target>/<name> for each target. Idempotent — won’t duplicate existing entries.

ensure_agent_file_ignored

pub fn ensure_agent_file_ignored(project_dir: &Path, filename: &str) -> Result<()>

Ensure a single file (e.g. CLAUDE.md) is listed in .gitignore. Idempotent — won’t duplicate an existing entry.

remove_skill_entries

pub fn remove_skill_entries(project_dir: &Path, skill_name: &str) -> Result<()>

Remove all gitignore entries for a specific skill. Removes any line ending with /<name> under the managed section. Cleans up the ”# Managed by ion” header if no managed entries remain.
