Failed to uninstall ${name}

Error message

Failed to uninstall ${name}

What it means

uninstallPlugin spawns `bun remove <name>` in the plugins directory and captures stdout/stderr. If the child exits non-zero it throws this bare error. Notably the captured stderr is discarded, so the message omits the underlying bun failure reason.

Solutions

1. Confirm the plugin is actually installed (`omp plugins list` or inspect ~/.omp/plugins/package.json dependencies)
2. Run `bun remove <name>` manually inside ~/.omp/plugins to see the real bun error
3. Delete the entry from ~/.omp/plugins/package.json and remove node_modules/<name> manually if the lockfile is inconsistent
4. Ensure the plugins directory is writable and not locked by another running instance

Example fix

// before
await uninstallPlugin("not-installed-plugin");
// after: check installed set first
const installed = await listPlugins();
if (installed.some(p => p.name === "not-installed-plugin")) {
	await uninstallPlugin("not-installed-plugin");
}

const plugins = await listPlugins();
if (!plugins.some(p => p.name === targetName)) return; // nothing to uninstall
const pkgJson = await Bun.file(path.join(agentDir, "plugins", "package.json")).json();
if (!pkgJson.dependencies?.[targetName]) return;

try {
	await uninstallPlugin(name);
} catch (err) {
	// Error message lacks bun stderr; inspect ~/.omp/plugins directly
	if (err instanceof Error && err.message.startsWith("Failed to uninstall")) {
		// fall back to manual cleanup: edit plugins/package.json + rm node_modules/<name>
	}
	throw err;
}

When it happens

Trigger: uninstallPlugin(name) is called while `bun remove` fails: the package is not present in PLUGINS_DIR/package.json dependencies or node_modules, the plugins package.json is corrupted, or another process holds a lock on the bun install directory.

Common situations: Trying to uninstall a plugin that was already removed or never installed via this mechanism; plugins installed by a different version of the CLI with a different layout; read-only or locked ~/.omp/plugins directory.
