add-plugin
Install a Claude Code plugin and register it in settings.json so the full team can replicate the install. Use this whenever adding a new plugin to the project — it keeps settings.json in sync with what is actually installed.

# Add Plugin
Role: implementation. This skill installs a Claude Code plugin and
adds it to `.claude/settings.json` so the project's plugin set is
reproducible.
You have been invoked with the `/add-plugin` skill.
## Implementation constraints
1. **Always update settings.json.** Installing without registering
defeats the purpose — the whole point is reproducibility.
2. **Derive marketplace from the identifier.** The `name@marketplace`
format encodes both; never ask the user to repeat information
already in the argument.
3. **Do not duplicate entries.** Check settings.json before adding;
if the plugin is already registered, report it and stop.
4. **Be concise.** Report only the outcome — no narration of each step.
## Parse Arguments
Arguments: $ARGUMENTS
Required: plugin identifier (`$0`) in `name@marketplace` format —
e.g. `skill-creator@claude-plugins-official` or `refactoring@refactoring`.
Optional:
- `--repo <owner/repo>`: GitHub repository to register as the
marketplace source before installing (e.g. `elifiner/refactoring`).
Required for plugins not on an official marketplace.
## Steps
### 1. Parse arguments
Extract:
- `NAME` — the part before `@` in `$0`
- `MARKETPLACE` — the part after `@` in `$0`
- `REPO` — value of `--repo`, or empty string if not provided
### 2. Check for existing registration
Read `.claude/settings.json`. If `enabledPlugins` already contains
`"<NAME>@<MARKETPLACE>": true`, report:
```
<NAME>@<MARKETPLACE> is already registered in settings.json. Nothing to do.
```
and stop.
### 3. Register marketplace (if --repo provided)
If `REPO` is non-empty, run:
```bash
claude plugin marketplace add <REPO>
```
If this fails, report the error and stop.
### 4. Install the plugin
Run:
```bash
claude plugin install <NAME>@<MARKETPLACE>
```
If this fails, report the error and stop — do not update settings.json
for a plugin that did not install successfully.
### 5. Add to settings.json
Add to the `enabledPlugins` object in `.claude/settings.json`:
```json
"<NAME>@<MARKETPLACE>": true
```
If a `--repo` was provided, also add to `extraKnownMarketplaces`:
```json
"<MARKETPLACE>": {
"source": {
"source": "github",
"repo": "<REPO>"
}
}
```
### 6. Report
```
Installed: <NAME>@<MARKETPLACE>
Repo: <REPO or "official marketplace">
settings.json: updated
```
