# Wave Settings Skill

This skill helps you manage your Wave configuration and provides guidance on how to use `settings.json`.

## What is `settings.json`?

`settings.json` is the central configuration file for Wave. It allows you to customize hooks, environment variables, tool permissions, and more.

### Live Reload

Changes to `settings.json` take effect immediately without restarting Wave. When you modify any setting, the new configuration is applied to subsequent operations automatically.

Wave looks for `settings.json` in three scopes:
1.  **User Scope**: Global settings for all projects. Located at `~/.wave/settings.json`.
2.  **Project Scope**: Settings specific to the current project. Located at `.wave/settings.json` in your project root.
3.  **Local Scope**: Local overrides for the current project (not committed to git). Located at `.wave/settings.local.json`.

## Common Settings

### 1. Hooks
Hooks allow you to automate tasks when certain events occur (e.g., `PreToolUse`, `PostToolUse`, `SessionStart`, `SessionEnd`).
For detailed hook configuration, see [HOOKS.md](${WAVE_SKILL_DIR}/HOOKS.md).

### 2. Environment Variables
Set environment variables that will be available to all tools and hooks. Common `WAVE_*` variables include:
- `WAVE_MODEL`, `WAVE_FAST_MODEL`: Model selection
- `WAVE_MAX_INPUT_TOKENS`, `WAVE_MAX_OUTPUT_TOKENS`: Token limits
- `WAVE_API_KEY`, `WAVE_BASE_URL`: API configuration

For detailed configuration, see [ENV.md](${WAVE_SKILL_DIR}/ENV.md).
```json
{
  "env": {
    "NODE_ENV": "development",
    "API_KEY": "your-api-key"
  }
}
```

### 3. Permissions
Manage tool permissions and define the "Safe Zone". Changes to permissions take effect immediately with live reload.
For detailed permission configuration and available permission modes, see [PERMISSIONS.md](${WAVE_SKILL_DIR}/PERMISSIONS.md).
```json
{
  "permissions": {
    "allow": ["Bash", "Read"],
    "deny": ["Write"],
    "permissionMode": "default",
    "additionalDirectories": ["/tmp/wave-exports"]
  }
}
```

### 4. Model Configuration
Define which AI models Wave should use and set model-specific parameters like `temperature`, `reasoning_effort`, and `thinking`. You can also configure model selection and token limits via environment variables in the `env` field.
For detailed model configuration, see [MODELS.md](${WAVE_SKILL_DIR}/MODELS.md).
```json
{
  "models": {
    "claude-3-7-sonnet-20250219": {
      "options": {
        "thinking": {
          "type": "enabled",
          "budget_tokens": 1024
        }
      }
    },
    "o3-mini": {
      "options": {
        "reasoning_effort": "high"
      }
    }
  }
}
```

### 5. Model Context Protocol (MCP)
Connect to external servers to provide additional tools and context.
For detailed MCP configuration, see [MCP.md](${WAVE_SKILL_DIR}/MCP.md).

### 6. Memory
Provide context-specific instructions and knowledge to the agent through user memory, project memory, memory rules, and auto-memory.
For detailed memory configuration, see [MEMORY.md](${WAVE_SKILL_DIR}/MEMORY.md).

### 7. Skills
Extend Wave's functionality by creating custom skills.
For detailed guidance on creating skills, see [SKILLS.md](${WAVE_SKILL_DIR}/SKILLS.md).

### 8. Subagents
Delegate tasks to specialized AI personalities.
For detailed guidance on creating subagents, see [SUBAGENTS.md](${WAVE_SKILL_DIR}/SUBAGENTS.md).

### 9. Plugins

Plugins bundle skills, hooks, MCP servers, LSP servers, commands, and subagents into a reusable package. You can install plugins locally or from a marketplace.
For detailed guidance on creating plugins and marketplaces, see [PLUGINS.md](${WAVE_SKILL_DIR}/PLUGINS.md).

### 10. Other Settings
- `language`: Preferred language for agent communication (e.g., `"en"`, `"zh"`).
- `autoMemoryEnabled`: Enable or disable auto-memory (default: `true`).
- `autoMemoryFrequency`: Frequency of auto-memory extraction turns (default: `1`).

## How to use this skill

You can ask me to:
- "Show my current settings"
- "Update my project settings to enable auto-memory"
- "How do I configure a post-commit hook?"
- "What are the available permission modes?"
- "Update my permission mode to acceptEdits"
- "How do I extend the Safe Zone for permissions?"
- "How do I create a custom skill?"
- "How do I define a new subagent?"
- "How do I set max input tokens?"
- "How do I change the model?"
- "How do I create a Wave plugin?"
- "How do I set up a plugin marketplace?"
- "How do I install a plugin from a marketplace?"

I will guide you through the process and ensure your configuration is valid.
