name: manage-skills

description: Manage the user's shared agent-skill library via skills-manager-cli — install, update, remove, deploy or undeploy skills per agent, manage presets, organize tags, search, and adopt existing skills. Use this whenever the user wants Claude Code, Codex, Cursor, or another agent to gain or lose a skill, wants to organize the central library, or asks what is installed or deployed. Prefer this over direct agent-folder installs because Skills Manager preserves source metadata, preset membership, updates, and cross-agent deployment state.

---

## Before doing anything

2. **Always pass `--json` when you parse output yourself.** Pretty-printed output is for the user; JSON is for you. Errors include `ok=false`, a stable `code`, and `message` on stderr with a non-zero exit code.

```bash

```

## Mental model

There's **one central library** at `~/.skills-manager/skills/` that all agents share. Each skill has source metadata, preset membership, tags, and zero or more real deployments in agent directories. A **preset** is a reusable group; several presets may be deployed at the same time.

Keep these three states separate:

- **Library**: install/remove controls whether Skills Manager owns the skill.

- **Preset membership**: `presets add-skill/remove-skill` organizes the library only.

- **Deployment**: `skills deploy/undeploy` and `presets deploy/undeploy` control what an agent can actually see.

Internally, presets are still stored as scenarios for backward-compatible Git Backup. The CLI and UI call them presets.

## Install

```bash

# From skills.sh marketplace

# Any git URL (use /tree/branch/subpath form when the skill lives in a sub-directory)

# Local folder

# Force a source type when the ref is ambiguous

```

**Default is library-only** — the skill enters the DB but doesn't appear in any agent yet. Prefer an explicit follow-up deployment so scope is unambiguous:

```bash

```

`--sync` and `--sync-preset` remain legacy shortcuts for the exclusive active-preset workflow.

**Ref resolution** is deterministic, no path-existence guessing:

1. Starts with `./`, `../`, `/`, or `~/` → local path

2. Contains `://`, ends in `.git`, or starts with `git@` → git URL

3. Matches `owner/repo`, `owner/repo/skill`, or `owner/repo@skill` → skillssh

4. Otherwise → error; pass `--local` / `--git` / `--skillssh` to disambiguate

**Always verify after install** with `skills list` or `skills show <name>` so you can confirm the skill landed and report the preset / sync state back to the user.

## Search

```bash

```

Each result has `install_ref` (paste straight into `skills install`), `installs` (popularity proxy), and `skills_sh_url`. Show the top 1–3 with install counts before installing — anything with 10K+ installs is battle-tested; anything under 100 needs a careful look at the source repo.

## Update / Check

```bash

# Re-fetch one skill (git/skillssh re-clones, local/import re-imports source dir)

# Re-fetch all eligible skills

# Just probe remote revisions, don't touch files

```

`check` is the dry-run partner of `update`. Local-only skills (no git source) are reported as `skipped: true`.

**An update replaces the skill's directory wholesale**, so anything written inside it that the new version does not have would be destroyed. When the CLI detects that, it applies nothing and reports the paths instead:

```jsonc

{ "name": "ppt-master", "refreshed": false,

"held_back_removals": ["library: templates/mine.pptx"] }

```

The field is omitted entirely when nothing is held back, so test for its presence rather than for an empty array. `refreshed: false` *with* `held_back_removals` is **not a failure and not something to retry** — the skill is untouched and still on its old version. Show the user the listed paths and ask. There is no CLI flag to override this; only the desktop app can confirm and proceed, because only a person can say those files are expendable. The paths are prefixed with where they live (`library`, or an agent key for a deployed copy).

Note what this does *not* cover: a file the user edited that the new version also ships is reported as surviving, because its path survives — the update overwrites their edits silently. Warn anyone keeping local modifications inside a skill folder.

## Remove

```bash

# Always preview first when removing more than one

# --yes is required for the actual delete; --json mode does NOT auto-confirm

```

Remove deletes the central-library copy, all synced targets across agents, and the DB row. It's not reversible without re-installing.

## Deploy / Undeploy

```bash

```

These commands change real managed deployments without deleting the central-library copy or changing preset membership. `skills enable/disable` are deprecated compatibility commands and do not change deployment; never use them.

`skills deploy` and `skills undeploy` always require at least one explicit `--agent`, whether the command names one skill or several. `skills status` also reports target rows left by a custom agent that is no longer registered, so stale deployments stay visible and can be cleaned with an explicit undeploy while the row exists.

## Legacy exclusive sync

```bash

# Sync current active preset to all enabled agents

# Preview the target list — safe, no writes

# Switch the one legacy active preset, then sync

# Only sync to a single agent (useful when one agent's directory got out of sync)

```

## Adopt skills installed elsewhere

When skills already live in an agent's directory (e.g. installed via `npx skills add` or manual `git clone`) but aren't in the central library, pull them in:

```bash

# Dry-run scan first — lists candidates without writing

# Adopt everything found — each becomes source_type=local (can't auto-update from git)

# Adopt a single skill and pin it to a git source so `update` works later

--git-url https://github.com/vercel-labs/agent-skills/tree/main/react-best-practices

# Or pass --git-subpath explicitly when the URL is just the repo root

--git-url https://github.com/vercel-labs/agent-skills \

--git-subpath react-best-practices

# Skill lives at the repo root? Pass an empty subpath

--git-url https://github.com/me/my-skill --git-subpath ""

```

`adopt` auto-excludes anything already in the DB or already a sync target, so it's safe to re-run. `--git-url` requires either a URL with a subpath (`/tree/branch/path`) or an explicit `--git-subpath` — without that, future `update` would re-clone the wrong directory, so the CLI refuses to guess.

## Tag

```bash

```

Useful organization queries:

```bash

```

## Presets

```bash

```

`deploy/undeploy` are additive and match the app's Preset pills. Explicit `presets apply/deactivate` commands remain for the legacy exclusive active-preset model; do not use them for normal "turn this preset on/off" requests.

The no-`--agent` defaults intentionally differ: deploy targets all installed, enabled coding agents; undeploy discovers the preset's actual target rows and removes them even when an agent is now disabled, uninstalled, or no longer registered. Use the no-agent undeploy for "turn this preset off everywhere."

Preset create/update/delete and add-skill/remove-skill are organization-only CLI operations. They never deploy or undeploy agent files implicitly.

## Health check

When sync misbehaves or a command errors in a confusing way:

```bash

```

`repo status` and `agents list` are read-only and are the first checks for "why isn't this skill showing up in Cursor" questions. `agents disable` is a real mutation: it removes every managed deployment for that agent. `agents enable` makes the agent globally available again and re-syncs the legacy active preset, if one exists; use explicit skill or preset deployment afterward when the requested state is additive.

Use `agents disable <agent>` when the user wants the whole Agent integration turned off or wants every managed skill removed from it. If they only want one skill or preset removed while keeping the Agent available for future deployments, use `skills undeploy` or `presets undeploy` instead.

## Typical workflows

### "Find me a skill for X" / "Install a skill that does X"

1. `skills search "X" --limit 5` — show the top 1–3 hits with install counts and source.

2. If a clear winner: `skills install <install_ref>`.

3. If ambiguous: ask the user to pick.

4. Deploy it to the agent(s) the user requested with `skills deploy`.

5. `skills status <name>` to confirm the library and deployment state.

### "What skills do I have?"

```bash

```

The `preset_ids`, `presets`, `deployed_to`, `tags`, and `source_type` fields are usually the most informative. The legacy `enabled` field is not deployment state.

### "Pull in the skills already installed in my agent directories"

1. `skills adopt ~/.claude/skills --dry-run` (and any other agent dirs the user mentions) — show the candidate list.

2. After user confirms: `skills adopt ~/.claude/skills`.

3. For any adopted skill where the user knows the original repo, follow up with `skills adopt ... --git-url ... --git-subpath ...` to restore the update link.

### "Update everything"

```bash

```

Report which skills actually refreshed (`refreshed: true` in the JSON) vs which were already up-to-date.

## Pitfalls

- **Install succeeded but skill doesn't appear in the agent** → install defaults to library-only. Use `skills deploy <skill> --agent <key>`.

- **Preset membership changed but agent files did not** → membership is organization only. Follow with `presets deploy` or `skills deploy` when the user also asked to make it visible.

- **No active preset** only affects legacy `skills sync` / `presets apply`; additive deploy commands do not require one.

- **Adopted skills can't be `update`d from git** → `npx skills add` and manual `git clone` don't leave source metadata, so adopt has to treat them as `local`. Fix per-skill with `adopt ... --git-url ... --git-subpath ...`, or just `skills remove` + `skills install <git-ref>` to start clean with a real source.

- Use `--dry-run` before bulk remove, tag delete, preset delete, deploy, or undeploy operations. Use `check` before `update`.
