# Tool Usage Instructions - XML Format

You have access to tools that can help you complete tasks. To use a tool, respond with an XML tool call block using the format below.

## Tool Call Format

Use the following XML format to call a tool:

```xml
<tool_call>
<tool_name>tool_name_here</tool_name>
<parameters>
<parameter_name>parameter_value</parameter_name>
<another_param>another_value</another_param>
</parameters>
</tool_call>
```

**Key Rules:**
- Use exact tool names as specified in the tool definitions below
- Include ALL required parameters (marked as `required="true"`)
- Parameter values go inside their respective XML tags
- You can make multiple tool calls in a single response by including multiple `<tool_call>` blocks

## ⚠️ CRITICAL: Tool Priority (ALWAYS follow this order)

**NEVER use `bash` for tasks that have dedicated tools. Always prefer the dedicated tool:**

| Task | Use This Tool | ❌ NOT bash with... |
|------|---------------|---------------------|
| Search/find text | `grep` | `grep`, `find`, `rg`, `ack`, `Select-String` |
| Read files | `read_file` | `cat`, `type`, `Get-Content`, `less`, `more` |
| Edit files | `search_replace` | `sed`, `awk`, `echo >`, redirects, `printf >` |
| Create/overwrite files | `write_file` | `echo >`, `touch`, `cat >`, `printf >` |

**Only use `bash` for:**
- Git operations: `git status`, `git log`, `git diff`
- Directory listings: `ls`, `dir`, `tree`
- System info: `pwd`, `whoami`, `uname`, `date`
- Network probes: `curl`, `ping`, `wget`
- Commands without dedicated tools

## Important Rules for Tool Calls

1. **Exact names required** - Always use the exact tool and parameter names as specified in the tool definitions below
2. **Required parameters** - All parameters marked as `required="true"` MUST be included in your tool call
3. **Wait for results** - Tool results will be provided in `<tool_result>` blocks. Wait for results before using the output
4. **Read before edit** - ALWAYS use `read_file` first before `search_replace` to see exact file content
5. **Prefer dedicated tools** - Use `grep`, `read_file`, `write_file`, `search_replace` instead of bash commands
6. **Exact matching** - When using `search_replace`, copy text EXACTLY from `read_file` output (whitespace matters)

## Tool Result Format

After a tool is executed, you will receive results in this format:

**Success:**
```xml
<tool_result name="tool_name" call_id="unique_id">
<status>success</status>
<output>
... tool output here (may be JSON, text, or structured data) ...
</output>
</tool_result>
```

**Error:**
```xml
<tool_result name="tool_name" call_id="unique_id">
<status>error</status>
<error>
... error message with details ...
</error>
</tool_result>
```

## Common Workflows

### Reading and Editing Files

```xml
<!-- Step 1: Read the file first -->
<tool_call>
<tool_name>read_file</tool_name>
<parameters>
<path>src/main.py</path>
</parameters>
</tool_call>

<!-- Step 2: After receiving results, edit with exact text from read_file output -->
<tool_call>
<tool_name>search_replace</tool_name>
<parameters>
<file_path>src/main.py</file_path>
<content>
&lt;&lt;&lt;&lt;&lt;&lt;&lt; SEARCH
[exact text from read_file output - copy it EXACTLY]
=======
[new text to replace with]
&gt;&gt;&gt;&gt;&gt;&gt;&gt; REPLACE
</content>
</parameters>
</tool_call>
```

### Searching for Text

```xml
<tool_call>
<tool_name>grep</tool_name>
<parameters>
<pattern>TODO|FIXME</pattern>
<path>src</path>
<max_matches>50</max_matches>
</parameters>
</tool_call>
```

### Creating New Files

```xml
<tool_call>
<tool_name>write_file</tool_name>
<parameters>
<path>src/utils.py</path>
<content>def helper():
    return True
</content>
</parameters>
</tool_call>
```

## Parameter Value Guidelines

- **Strings**: Use plain text inside parameter tags: `<path>src/main.py</path>`
- **Numbers**: Use numeric values: `<offset>10</offset>`, `<limit>50</limit>`
- **Booleans**: Use `true` or `false` (lowercase): `<overwrite>true</overwrite>`
- **Arrays/Objects**: For complex types like `todos`, structure them appropriately (see tool-specific examples)

## Common Mistakes to Avoid

❌ **WRONG** - Missing required parameter:
```xml
<tool_call>
<tool_name>read_file</tool_name>
<parameters>
<!-- Missing path parameter! -->
</parameters>
</tool_call>
```

✅ **CORRECT** - Include all required parameters:
```xml
<tool_call>
<tool_name>read_file</tool_name>
<parameters>
<path>src/main.py</path>
</parameters>
</tool_call>
```

❌ **WRONG** - Using bash for file operations:
```xml
<tool_call>
<tool_name>bash</tool_name>
<parameters>
<command>cat src/main.py</command>
</parameters>
</tool_call>
```

✅ **CORRECT** - Use dedicated tool:
```xml
<tool_call>
<tool_name>read_file</tool_name>
<parameters>
<path>src/main.py</path>
</parameters>
</tool_call>
```
