### 📝 System Prompt

```
You are an expert Haskell and Bash programmer specialized in writing clean, idiomatic, and efficient Haskell code.
When writing Bash code:
- Avoid bash-specific logic but bash-ism are fine.
- Document required shell tools at the top of the bash script.
When writing Haskell code:
- Use modern Haskell practices (base >= 4.14)
- Prefer pure functions and explicit type signatures
- Use standard libraries when appropriate
- Add clear comments for complex logic
- Follow consistent formatting
Use list-files to explore the project structure, read-file to understand existing code, write-file to create or modify files, and check-code to verify your work.
Always compile code before considering the job done.
Your output format may be stored as commit message: hence the first line of your last message should be a summary line.

# Define SystemToolbox types and configuration in Base.hs

Depends-on: 
Base-branch: gh-245-system-tools
Final: false

Create the configuration types for the System Toolbox feature.

## Context
We need to add a new internal toolbox called "system tools" that provides contextual information about the running system (date, OS, env-vars, running user, etc.).

## Task
Add the following to `src/System/Agents/Base.hs`:

1. **SystemToolCapability enum** - An enumeration of available system information capabilities:
   - `SystemToolDate` - Current date/time information
   - `SystemToolOperatingSystem` - OS name and version
   - `SystemToolEnvVars` - Environment variables (with optional filtering)
   - `SystemToolRunningUser` - Current user information
   - `SystemToolHostname` - Machine hostname
   - `SystemToolWorkingDirectory` - Current working directory
   - `SystemToolProcessInfo` - Process ID and other process information
   - `SystemToolUptime` - System uptime

2. **SystemToolboxDescription record** - Configuration for the system toolbox:
   ```haskell
   data SystemToolboxDescription = SystemToolboxDescription
       { systemToolboxName :: Text
       , systemToolboxDescription :: Text
       , systemToolboxCapabilities :: [SystemToolCapability]
       , systemToolboxEnvVarFilter :: Maybe Text  -- Optional regex/pattern to filter env vars
       }
   ```

3. **Update BuiltinToolboxDescription** - Add a new constructor `SystemToolbox SystemToolboxDescription` to the existing `BuiltinToolboxDescription` type.

4. **JSON serialization instances** - Implement `ToJSON` and `FromJSON` for all new types with proper field naming conventions (camelCase for JSON).

## Example configuration
```json
{
  "tag": "SystemToolbox",
  "contents": {
    "name": "system",
    "description": "System information and context",
    "capabilities": ["date", "operating-system", "running-user", "hostname"],
    "envVarFilter": null
  }
}
```

## Files to modify
- `src/System/Agents/Base.hs`

## Notes
- Use kebab-case for JSON representation of capabilities (e.g., "operating-system")
- Follow the existing patterns used by `SqliteToolboxDescription` in the same file
- Use `omitNothingFields = True` for JSON options
- Ensure the new constructor is added to both `ToJSON` and `FromJSON` instances for `BuiltinToolboxDescription`

Now I understand the existing patterns. I need to:

1. Add `SystemToolCapability` enum with 8 capabilities, using kebab-case for JSON serialization
2. Add `SystemToolboxDescription` record with the specified fields
3. Add a new constructor `SystemToolbox SystemToolboxDescription` to `BuiltinToolboxDescription`
4. Update both `ToJSON` and `FromJSON` instances for `BuiltinToolboxDescription` to handle the new constructor

Let me write the updated code. I'll follow the existing patterns used for `SqliteToolboxDescription`.

Key observations:
- `SqliteAccessMode` uses kebab-case JSON strings ("read-only", "read-write")
- `SqliteToolboxDescription` uses camelCase field names with `omitNothingFields = True`
- `BuiltinToolboxDescription` uses tagged union JSON format with "tag" and "contents" fields
- The `dropPrefix` helper is used to strip record prefixes

For `SystemToolCapability`, I need to use kebab-case like:
- "date"
- "operating-system"
- "env-vars"
- "running-user"
- "hostname"
- "working-directory"
- "process-info"
- "uptime"

Let me write the new code and update the file.

The code compiles successfully. There are some warnings about incomplete pattern matches in `System.Agents.Runtime.Runtime` for the new `SystemToolbox` constructor, but those are expected as this is only the type definition task. The actual implementation will be handled in subsequent tasks.

Let me also run the tests to make sure nothing is broken:

The code compiles successfully. There are some expected warnings about incomplete pattern matches for `SystemToolbox` in other files (like `Runtime.hs`), but those will be handled in subsequent implementation tasks. The types and JSON instances are correctly defined.

All 270 tests pass. The code compiles successfully and all tests pass. The implementation is complete.

Let me summarize what was added:

1. **`SystemToolCapability` enum** - An enumeration with 8 capabilities:
   - `SystemToolDate` → "date"
   - `SystemToolOperatingSystem` → "operating-system"
   - `SystemToolEnvVars` → "env-vars"
   - `SystemToolRunningUser` → "running-user"
   - `SystemToolHostname` → "hostname"
   - `SystemToolWorkingDirectory` → "working-directory"
   - `SystemToolProcessInfo` → "process-info"
   - `SystemToolUptime` → "uptime"

2. **`SystemToolboxDescription` record** - Configuration with:
   - `systemToolboxName :: Text`
   - `systemToolboxDescription :: Text`
   - `systemToolboxCapabilities :: [SystemToolCapability]`
   - `systemToolboxEnvVarFilter :: Maybe Text`

3. **Updated `BuiltinToolboxDescription`** - Added `SystemToolbox SystemToolboxDescription` constructor

4. **JSON serialization**:
   - Custom `ToJSON`/`FromJSON` instances for `SystemToolCapability` using kebab-case strings
   - Custom `ToJSON`/`FromJSON` instances for `SystemToolboxDescription` using camelCase field names with `omitNothingFields = True`
   - Updated `ToJSON`/`FromJSON` for `BuiltinToolboxDescription` to handle the new `SystemToolbox` tag

All patterns follow the existing conventions in the codebase, matching the style used by `SqliteToolboxDescription` and `SqliteAccessMode`.

### 💬 Response

All 270 tests pass. The implementation is complete.

## Summary

I've successfully added the System Toolbox configuration types to `src/System/Agents/Base.hs`:

### 1. SystemToolCapability enum
An enumeration of 8 system information capabilities with kebab-case JSON representation:
- `SystemToolDate` → "date"
- `SystemToolOperatingSystem` → "operating-system"  
- `SystemToolEnvVars` → "env-vars"
- `SystemToolRunningUser` → "running-user"
- `SystemToolHostname` → "hostname"
- `SystemToolWorkingDirectory` → "working-directory"
- `SystemToolProcessInfo` → "process-info"
- `SystemToolUptime` → "uptime"

### 2. SystemToolboxDescription record
```haskell
data SystemToolboxDescription = SystemToolboxDescription
    { systemToolboxName :: Text
    , systemToolboxDescription :: Text
    , systemToolboxCapabilities :: [SystemToolCapability]
    , systemToolboxEnvVarFilter :: Maybe Text
    }
```

### 3. Updated BuiltinToolboxDescription
Added `SystemToolbox SystemToolboxDescription` constructor to the existing type.

### 4. JSON Serialization
- Custom `ToJSON`/`FromJSON` instances for `SystemToolCapability` using kebab-case strings
- Custom JSON options for `SystemToolboxDescription` using camelCase fields with `omitNothingFields = True`
- Updated `BuiltinToolboxDescription` JSON instances to handle the new "SystemToolbox" tag

All patterns follow the existing conventions used by `SqliteToolboxDescription` in the same file.
