# Refresh Antigravity Local Environment

Follow these steps to refresh Antigravity's local environment, ensuring that
their agent skills and plugins are fully up-to-date.

Antigravity relies on `npx skills`. Updates should prioritize the global level;
if skills are installed at the project level, omit the `--global` flag.

1. **List Available Skills:** Identify all Firebase skills available in the
   repository:

   ```bash
   npx -y skills add firebase/agent-skills --list
   ```

1. **Check Currently Installed Skills:** Determine which skills are already
   installed and linked at both project and global levels:

   ```bash
   # Check project-level skills
   npx -y skills list --agent antigravity

   # Check global-level skills
   npx -y skills list --agent antigravity --global
   ```

   *Note: If a skill shows `Agents: not linked` in the output, it is installed
   but not currently available to Antigravity.*

1. **Add Missing or Unlinked Skills:** Compare the results from Step 1 and Step
   2\. For each missing or unlinked skill, follow the appropriate conditional
   instruction below:

   - **IF any Firebase skills were found at the PROJECT level in Step 2:** Add
     the missing skill to the project level:

     ```bash
     npx -y skills add firebase/agent-skills --agent antigravity --skill "<SKILL_NAME>" --yes
     ```

   - **IF any Firebase skills were found at the GLOBAL level in Step 2:** Add
     the missing skill to the global level:

     ```bash
     npx -y skills add firebase/agent-skills --agent antigravity --skill "<SKILL_NAME>" --global --yes
     ```

   - **IF NO Firebase skills were found in Step 2:** Add each missing skill to
     the global level:

     ```bash
     npx -y skills add firebase/agent-skills --agent antigravity --skill "<SKILL_NAME>" --global --yes
     ```

1. **Update Existing Skills:** Update all currently installed skills to their
   latest versions:

   ```bash
   # Update project-level skills
   npx -y skills update --agent antigravity --yes

   # Update global-level skills
   npx -y skills update --agent antigravity --global --yes
   ```
