### 📝 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.

### 💬 User Query

# Add systemTool builder and registration in Tools.hs and ToolRegistration.hs

Depends-on: #248
Base-branch: gh-245-system-tools
Final: false

Add the tool builder and registration functions for SystemToolbox tools.

## Context
Depends on #248 which adds SystemTool to the base types. This provides the integration with the LLM system.

## Task

### Part 1: Update `src/System/Agents/Tools.hs`

1. **Import SystemToolbox**:
   ```haskell
   import qualified System.Agents.Tools.SystemToolbox as SystemTools
   ```

2. **Add `systemTool` builder function** (similar to `sqliteTool`):
   ```haskell
   {- | Builder for a SystemToolbox-based tool.
   
   This creates a tool that provides system information based on configured capabilities.
   The tool accepts a single parameter 'capability' specifying which information to retrieve.
   -}
   systemTool :: SystemTools.Toolbox -> Tool ()
   systemTool box =
       Tool
           { toolDef = SystemTool toolDesc
           , toolRun = run
           }
     where
       call = ()
       toolDesc = SystemTools.ToolDescription
           { SystemTools.toolDescriptionName = "system_info"
           , SystemTools.toolDescriptionDescription = box.toolboxDescription
           , SystemTools.toolDescriptionToolboxName = box.toolboxName
           }
       run _tracer _ctx (Aeson.Object v) = do
           case KeyMap.lookup (AesonKey.fromText "capability") v of
               Just (Aeson.String cap) -> do
                   result <- SystemTools.executeQuery box cap
                   case result of
                       Left err -> pure $ SystemToolError call err
                       Right rsp -> pure $ SystemToolResult call rsp
               _ -> pure $ SystemToolError call (SystemTools.SystemInfoError "Missing 'capability' parameter or invalid type")
       run _tracer _ctx _ = do
           pure $ SystemToolError call (SystemTools.SystemInfoError "Arguments must be a JSON object")
   ```

### Part 2: Update `src/System/Agents/ToolRegistration.hs`

1. **Import SystemToolbox**:
   ```haskell
   import qualified System.Agents.Tools.SystemToolbox as SystemTools
   ```

2. **Add naming policy function**:
   ```haskell
   {- | Naming policy for System tools.
   
   Generates an LLM-safe tool name in the format: @system_{toolboxName}_{toolName}@
   -}
   system2LLMName :: SystemTools.Toolbox -> Text -> OpenAI.ToolName
   system2LLMName box toolName =
       OpenAI.ToolName (mconcat ["system_", box.toolboxName, "_", toolName])
   ```

3. **Add registration function**:
   ```haskell
   {- | Register a SystemToolbox tool with the LLM system.
   
   System tools expose functions based on configured capabilities.
   The tool accepts a 'capability' parameter to select which information to retrieve.
   -}
   registerSystemTool ::
       SystemTools.Toolbox ->
       Either String ToolRegistration
   registerSystemTool box =
       let
           toolName = "system_info"
           llmName = system2LLMName box toolName

           -- Single parameter: the capability to query
           paramProps =
               [ ParamProperty
                   { propertyKey = "capability"
                   , propertyType = StringParamType
                   , propertyDescription = "Capability to query: " <> Text.intercalate ", " (map capabilityToText box.toolboxCapabilities)
                   , propertyRequired = True
                   }
               ]

           openaiTool =
               OpenAI.Tool
                   { OpenAI.toolName = llmName
                   , OpenAI.toolDescription = "Provides system information: " <> box.toolboxDescription
                   , OpenAI.toolParamProperties = paramProps
                   }

           -- Create the tool
           tool' = systemTool box

           -- Find function - matches on the LLM name
           find :: OpenAI.ToolCall -> Maybe (Tool OpenAI.ToolCall)
           find call =
               if call.toolCallFunction.toolCallFunctionName == llmName
                   then Just $ mapToolResult (const call) tool'
                   else Nothing
        in
           Right $
               ToolRegistration
                   { innerTool = mapToolResult (const ()) tool'
                   , declareTool = openaiTool
                   , findTool = find
                   }

   -- Helper to convert capability to text
   capabilityToText :: SystemTools.SystemToolCapability -> Text
   capabilityToText SystemTools.SystemToolDate = "date"
   capabilityToText SystemTools.SystemToolOperatingSystem = "operating-system"
   capabilityToText SystemTools.SystemToolEnvVars = "env-vars"
   capabilityToText SystemTools.SystemToolRunningUser = "running-user"
   capabilityToText SystemTools.SystemToolHostname = "hostname"
   capabilityToText SystemTools.SystemToolWorkingDirectory = "working-directory"
   capabilityToText SystemTools.SystemToolProcessInfo = "process-info"
   capabilityToText SystemTools.SystemToolUptime = "uptime"
   ```

4. **Add `registerSystemTools` function**:
   ```haskell
   {- | Register all tools from a System toolbox.
   Currently System toolboxes expose a single system_info tool.
   -}
   registerSystemTools ::
       SystemTools.Toolbox ->
       IO (Either String [ToolRegistration])
   registerSystemTools box =
       pure $ case registerSystemTool box of
           Left err -> Left err
           Right reg -> Right [reg]
   ```

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

## Notes
- The tool exposes a single "system_info" function with a "capability" parameter
- The description should list available capabilities for the LLM
- Follow the exact same pattern as `registerSqliteTool` and `registerSqliteTools`

I see the issue. The `SystemToolCapability` type is defined in `System.Agents.Base`, not in `System.Agents.Tools.SystemToolbox`. Looking at the SystemToolbox.hs file, I can see that it imports `SystemToolCapability` from `System.Agents.Base`.

The SystemToolbox module doesn't export `SystemToolCapability` - it's only the `Toolbox` that contains the `[SystemToolCapability]`. So I need to:
1. Import `SystemToolCapability` from `System.Agents.Base`
2. Use the proper constructors from `System.Agents.Base`

Let me update the ToolRegistration.hs file to fix this.

All 270 tests passed. The implementation is complete. Let me summarize what was done:

1. **Updated `src/System/Agents/Tools.hs`**:
   - Added import for `System.Agents.Tools.SystemToolbox` as `SystemTools`
   - Added `systemTool` builder function that creates a tool for gathering system information
   - The function accepts a `SystemTools.Toolbox` and returns a `Tool ()`
   - The tool accepts a JSON object with a "capability" parameter to select which system information to retrieve

2. **Updated `src/System/Agents/ToolRegistration.hs`**:
   - Added import for `System.Agents.Tools.SystemToolbox` as `SystemTools`
   - Added import for `SystemToolCapability` from `System.Agents.Base`
   - Added `system2LLMName` naming policy function that generates LLM-safe tool names in the format: `system_{toolboxName}_{toolName}`
   - Added `registerSystemTool` function that registers a SystemToolbox tool with the LLM system
   - Added helper function `capabilityToText` to convert `SystemToolCapability` to text representation
   - Added `registerSystemTools` function that registers all tools from a System toolbox (currently exposes a single system_info tool)
   - Added internal `systemTool` builder (copied pattern from other tool builders to avoid import cycle)

The implementation follows the same patterns as the existing `sqliteTool` and `registerSqliteTool` functions, ensuring consistency with the codebase.
</details>

### 💬 Response

2. **Added `systemTool` builder function**: Creates a tool that provides system information based on configured capabilities. The tool accepts a single `capability` parameter to select which information to retrieve.

### Changes to `src/System/Agents/ToolRegistration.hs`:
1. **Added imports**: 
   - `import qualified System.Agents.Tools.SystemToolbox as SystemTools`
