# Settings

Pi uses JSON settings files with project settings overriding global settings.

| Location | Scope |
|----------|-------|
| `~/.jensen/agent/settings.json` | Global (all projects) |
| `.jensen/settings.json` | Project (current directory) |

Edit directly or use `/settings` for common options.

## All Settings

  }
}
```

### Compaction

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `compaction.enabled` | boolean | `true` | Enable auto-compaction |
| `compaction.reserveTokens` | number | `16384` | Tokens reserved for LLM response |
| `compaction.keepRecentTokens` | number | `20000` | Recent tokens to keep (not summarized) |

```json
{
  "compaction": {
    "enabled": true,
    "reserveTokens": 16384,
    "keepRecentTokens": 20000
  }
}
```

### Branch Summary

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `branchSummary.reserveTokens` | number | `16384` | Tokens reserved for branch summarization |

### Retry

| Setting | Type | Default | Description |

When a provider requests a retry delay longer than `maxDelayMs` (e.g., Google's "quota will reset after 5h"), the request fails immediately with an informative error instead of waiting silently. Set to `0` to disable the cap.

```json
{
  "retry": {
    "enabled": true,

    "baseDelayMs": 2000,
    "maxDelayMs": 60000
  }

| `shellCommandPrefix` | string | - | Prefix for every bash command (e.g., `"shopt -s expand_aliases"`) |

### Tools

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `tools.defaultActiveToolNames` | string[] | - | Default built-in tool names to activate for new sessions. Unknown names are ignored. If the configured list is empty or every name is invalid, Pi falls back to the legacy default tool set. |

```json
{
  "tools": {
    "defaultActiveToolNames": ["read", "bash", "edit", "write"]
  }
}
```

Explicit tool configuration passed in code still overrides this setting. This setting only controls the default built-in tool set chosen when no explicit tool list is provided.

### Model Cycling

}
```

### Markdown

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `markdown.codeBlockIndent` | string | `"  "` | Indentation for code blocks |

### Resources

These settings define where to load extensions, skills, prompts, and themes from.

Paths in `~/.jensen/agent/settings.json` resolve relative to `~/.jensen/agent`. Paths in `.jensen/settings.json` resolve relative to `.jensen`. Absolute paths and `~` are supported.

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `packages` | array | `[]` | npm/git packages to load resources from |
| `extensions` | string[] | `[]` | Local extension file paths or directories |
| `skills` | string[] | `[]` | Local skill file paths or directories |
| `prompts` | string[] | `[]` | Local prompt template paths or directories |
| `themes` | string[] | `[]` | Local theme file paths or directories |
| `enableSkillCommands` | boolean | `true` | Register skills as `/skill:name` commands |

Arrays support glob patterns and exclusions. Use `!pattern` to exclude. Use `+path` to force-include an exact path and `-path` to force-exclude an exact path.

#### packages

String form loads all resources from a package:

```json
{
  "packages": ["pi-skills", "@org/my-extension"]
}
```

Object form filters which resources to load:

```json
{
  "packages": [
    {
      "source": "pi-skills",
      "skills": ["brave-search", "transcribe"],
      "extensions": []
    }
  ]
}
```

See [packages.md](packages.md) for package management details.

## Example

```json
{
  "defaultProvider": "anthropic",
  "defaultModel": "claude-sonnet-4-20250514",
  "defaultThinkingLevel": "medium",
  "theme": "dark",
  "compaction": {
    "enabled": true,
    "reserveTokens": 16384,
    "keepRecentTokens": 20000
  },
  "retry": {
    "enabled": true,
    "maxRetries": 3
  },
  "enabledModels": ["claude-*", "gpt-4o"],
  "packages": ["pi-skills"]
}
```

## Project Overrides

Project settings (`.jensen/settings.json`) override global settings. Nested objects are merged:

```json
// ~/.jensen/agent/settings.json (global)
{
  "theme": "dark",
  "compaction": { "enabled": true, "reserveTokens": 16384 }
}

// .jensen/settings.json (project)
{
  "compaction": { "reserveTokens": 8192 }
}

// Result
{
  "theme": "dark",
  "compaction": { "enabled": true, "reserveTokens": 8192 }
}
```
": 8192 }
}
```
