¿Qué hace skillctl?

Operational playbook for managing Agent Skills with the skillctl CLI. Run real commands; do not simulate output or copy SKILL.md files between agent directories by hand.

Golden rules

1. One canonical store — skills live in ~/.skillctl/skills/<name>/; agents get symlinks via sync.
2. Commit manifest + lock — track agent-skills.json and agent-skills.lock in git for team reproducibility.
3. Portable specifiers only — use file:./<path>, local:imported/<name>, github:, npm:, or skills.sh/; never commit absolute homedir paths.
4. Install before sync — install materializes the store; sync only re-links agents.
5. Verify after changes — run skillctl doctor (and skillctl audit in CI).
6. Prefer import over manual copy — use import from-project or import from-npx instead of duplicating skill folders.

Decision tree

Situation	Command
New project, no manifest	skillctl init or skillctl init --with-skill
Add a remote or local skill	skillctl add <specifier> then skillctl install
Skills already in .claude/skills, .codex/skills, etc.	skillctl import from-project
Migrating from npx skills	skillctl import from-npx
Re-link only (lock unchanged)	skillctl sync
Re-fetch from upstream	skillctl update or skillctl update <name>
CI reproducible install	skillctl install --frozen then skillctl audit --strict
Non-portable paths in lock	skillctl install to rewrite; check skillctl doctor warnings

Quick recipes

# Bootstrap
skillctl init --with-skill
skillctl add github:vercel-labs/agent-skills#web-design-guidelines
skillctl install

# Project-local skill
skillctl add file:./my-skill
skillctl install
skillctl sync

# Import existing agent dirs
skillctl import from-project --dry-run
skillctl import from-project

# Inspect
skillctl list
skillctl doctor
skillctl audit --json

Expected after add file:./my-skill + install: manifest specifier file:./my-skill, lock canonicalPath like ~/.skillctl/skills/my-skill.

Portability (0.3.1+)

• Portable: file:./rel, local:imported/<name>, remote specifiers, canonicalPath: ~/.skillctl/skills/<name>.
• Not portable: absolute file:/Users/..., local:/abs/path, absolute canonicalPath from another machine.
• If doctor warns about non-portable paths, run skillctl install to rewrite lock from manifest.

Failure modes

Symptom	Action
canonical path missing	skillctl install
Integrity mismatch	skillctl update <name> or skillctl install
Symlink fails (Windows)	doctor notes; config defaultMode: copy
No agents linked	skillctl sync; enable agents in ~/.skillctl/config.json
Frozen install failed	Store out of sync; run install without --frozen
