🛠️ Development

To load the plugin from a local clone (session-only):

claude --plugin-dir /path/to/cloned/repo

To make it persistent, register the repo as a local marketplace in ~/.claude/settings.json:

{
  "extraKnownMarketplaces": {
    "local": {
      "source": {
        "source": "directory",
        "path": "/path/to/cloned/repo"
      }
    }
  }
}

Then install once:

claude plugin install cortex@local

After pulling new changes, update with:

claude plugin update cortex@local

These are personal skills for my workflow. Feel free to fork and adapt for your own use.

When adding or updating skills, use Anthropic's skill-creator skill so new skills match the expected format and conventions.
