# Add SQLite tool types to System.Agents.Tools.Base

Depends-on: #226
Base-branch: gh-builtin-toolbox
Final: false

## Task

Update `System.Agents.Tools.Base` to add support for SQLite tools in the tool system.

## Background

The `Tools.Base` module defines the core tool types and result types used throughout the system. We need to add SQLite-specific variants.

## Changes Required

### 1. Add SqliteToolbox import

Add import for the new `SqliteToolbox` module (created in #226):

```haskell
import qualified System.Agents.Tools.SqliteToolbox as SqliteTools
```

### 2. Extend ToolDef

Add a new constructor to `ToolDef`:

```haskell
data ToolDef
    = BashTool !BashTools.ScriptDescription
    | MCPTool !McpTools.ToolDescription
    | IOTool !IOTools.IOScriptDescription
    | OpenAPITool !Text !Text  -- Toolbox name and operation ID
    | PostgRESTool !Text !Text  -- Toolbox name and table path
    | SqliteTool !SqliteTools.ToolDescription  -- NEW
    deriving (Show)
```

### 3. Extend CallResult

Add new result constructors:

```haskell
data CallResult call
    = BlobToolSuccess call ByteString
    | ToolNotFound call
    | BashToolError call BashTools.RunScriptError
    | IOToolError call IOTools.RunError
    | McpToolResult call Mcp.CallToolResult
    | McpToolError call String
    | OpenAPIToolResult call ToolResult
    | OpenAPIToolError call String
    | PostgRESToolResult call PostgRESTypes.ToolResult
    | PostgRESToolError call String
    | SqliteToolResult call SqliteTools.QueryResult  -- NEW
    | SqliteToolError call SqliteTools.QueryError   -- NEW
    deriving (Show)
```

### 4. Update mapCallResult

Add cases for the new result types:

```haskell
mapCallResult f c =
    case c of
        ...existing cases...
        (SqliteToolResult c r) -> SqliteToolResult (f c) r
        (SqliteToolError c e) -> SqliteToolError (f c) e
```

### 5. Update extractCall

Add cases for the new result types:

```haskell
extractCall (SqliteToolResult c _) = c
extractCall (SqliteToolError c _) = c
```

### 6. Update callResultByteSize

Add cases for size calculation:

```haskell
callResultByteSize (SqliteToolResult _ result) =
    fromIntegral (LByteString.length (Aeson.encode result))
callResultByteSize (SqliteToolError _ err) =
    fromIntegral (LByteString.length (Aeson.encode (Aeson.String (Text.pack $ show err))))
```

## Files to Modify

- `src/System/Agents/Tools/Base.hs`

## Testing

- Ensure module compiles with new types
- Verify JSON serialization of results works correctly

## Tradeoffs

- Adding SqliteToolResult with structured data allows better error handling and result inspection than just returning raw bytes
- The QueryResult type from SqliteToolbox should be JSON-serializable (Aeson.ToJSON instance)

I see - the SqliteToolbox module doesn't export a `ToolDescription` type. Looking back at the SqliteToolbox.hs file, I don't see a `ToolDescription` data type defined. Let me check the module exports again:

```haskell
module System.Agents.Tools.SqliteToolbox (
    -- * Core types
    Trace (..),
    Toolbox (..),
    QueryError (..),
    QueryResult (..),
    ...
```

So the types exported are `Trace`, `Toolbox`, `QueryError`, and `QueryResult`, but there's no `ToolDescription`. Looking at the task description again, it says to add a `SqliteTool` constructor with `SqliteTools.ToolDescription`, but this type doesn't exist yet.

This might be intentional - perhaps the `ToolDescription` is supposed to be a new type that needs to be added to SqliteToolbox as part of the dependency #226, or maybe I should be using a different type. Let me look at how other toolboxes define their tool descriptions.

Looking at McpToolbox, it has a `ToolDescription` type. Let me check what it looks like:

### 💬 Response

I see that `SqliteTools.ToolDescription` doesn't exist in the SqliteToolbox module. Let me check how other toolboxes define their tool descriptions:

I see - in McpToolbox, `ToolDescription` is defined as `newtype ToolDescription = ToolDescription {getToolDescription :: Mcp.Tool}`. This is a wrapper around the MCP Tool type.

Since the task is to add SQLite tools to the tool system, I need to define a similar type for SQLite tools. Looking at the SqliteToolbox module, I need to add a `ToolDescription` type that describes a SQLite tool/query.

Let me check the SqliteToolbox module again and see if I need to add the ToolDescription type there or if it should be added to the Base.hs differently.

Looking at the existing tool types:
1. `BashTool !BashTools.ScriptDescription` - uses ScriptDescription
2. `MCPTool !McpTools.ToolDescription` - uses ToolDescription (newtype wrapper)
3. `IOTool !IOTools.IOScriptDescription` - uses IOScriptDescription
4. `OpenAPITool !Text !Text` - uses two Texts (toolbox name and operation ID)
5. `PostgRESTool !Text !Text` - uses two Texts (toolbox name and table path)

So the pattern is that each toolbox provides its own description type. For SQLite, since the module doesn't have a ToolDescription yet, I should add one to the SqliteToolbox module.

Looking at the task description more carefully, it says "Depends-on: #226" which means the SqliteToolbox module was created in #226. The task expects a `ToolDescription` type to exist. I should add this type to the SqliteToolbox module.

Let me add the `ToolDescription` type to SqliteToolbox.hs. Based on the pattern from other tools, it should contain information about the SQLite tool like name, description, database path, etc.

Let me check what information would be appropriate for a SQLite tool description by looking at what the SqliteToolbox already has.

Now I need to add a `ToolDescription` type to the SqliteToolbox module. Looking at the pattern from McpToolbox, this type should wrap or contain information about a SQLite tool. Since SQLite tools are essentially queries that can be executed against a database, I should define a type that describes such a tool.

The code compiles successfully. There are some warnings about incomplete pattern matches in other files (`System.Agents.OneShot` and `System.Agents.MCP.Server`), but those are expected since we're adding new constructors and those files haven't been updated yet. The main task was to update `System.Agents.Tools.Base` which is done.

All 270 tests passed. The code compiles and all existing tests still pass. The changes I made are:

1. Added import for `SqliteToolbox` module in `System.Agents.Tools.Base`
2. Added `SqliteTool` constructor to `ToolDef` data type
3. Added `SqliteToolResult` and `SqliteToolError` constructors to `CallResult` data type
4. Updated `mapCallResult` with cases for the new result types
5. Updated `extractCall` with cases for the new result types
6. Updated `callResultByteSize` with cases for the new result types

I also had to add the `ToolDescription` type and `ToJSON` instance for `QueryResult` in the `SqliteToolbox` module since those were required for the Base module to compile.

Let me summarize what was done.

### 💬 Response

All tests pass. Let me provide a summary of the changes made:

## Summary

Successfully added SQLite tool types to `System.Agents.Tools.Base` as specified in the task.

### Changes to `src/System/Agents/Tools/Base.hs`:

1. **Added SqliteToolbox import**:
   ```haskell
   import qualified System.Agents.Tools.SqliteToolbox as SqliteTools
   ```

2. **Extended `ToolDef`** with new constructor:
   ```haskell
   | SqliteTool !SqliteTools.ToolDescription  -- ^ SQLite tool description
   ```

3. **Extended `CallResult`** with two new constructors:
   ```haskell
   | SqliteToolResult call SqliteTools.QueryResult
   | SqliteToolError call SqliteTools.QueryError
   ```

4. **Updated `mapCallResult`** with cases for the new result types

5. **Updated `extractCall`** with cases for the new result types

6. **Updated `callResultByteSize`** with cases for size calculation of SQLite results

### Changes to `src/System/Agents/Tools/SqliteToolbox.hs`:

1. **Added `ToolDescription` export** and data type:
   ```haskell
   data ToolDescription = ToolDescription
       { toolDescriptionName :: Text
       , toolDescriptionDescription :: Text
       , toolDescriptionToolboxName :: Text
       , toolDescriptionDatabasePath :: FilePath
       }
   ```

2. **Added `ToJSON` instance for `QueryResult`** to support JSON serialization needed by `callResultByteSize`

The module compiles successfully and all 270 existing tests pass. The warnings about incomplete pattern matches in other files (`OneShot.hs` and `MCP.Server.hs`) are expected as those modules will need separate updates to handle the new SQLite tool result types.
