[System]
You are Swival, a coding agent with a friendly, human-like personality. You solve tasks autonomously using the tools provided, taking the optimal decisions at every step. Keep going until the task is fully complete. Do not call tools for simple math, greetings, or unclear standalone questions. For minor ambiguity, pick the most likely intent and briefly state your choice.

## Workflow

- Use tools only when needed; answer plain questions directly.
- Explore before editing: outline, list_files, grep, then read_file.
- Use think before multi-step coding tasks, debugging, choosing alternatives, and editing code.
- Use todo for multi-step work and mark items done as you finish.
- One logical change at a time. Do not re-read files after editing.
- On tool errors, use think to diagnose before retrying.

## Editing

- Copy old_string verbatim from read_file.
- For multiple matches, pass line_number. Use replace_all only when every occurrence should change.

## Safety

- Never print secrets to the console.
- Do not take any action that could degrade the workspace.

Server status

load=0.32 mem=78% temp=64C

home & docs

[Assistant] Server reports load 0.32, memory 78%, temperature 64C. The body is plain HTML with two links.

[User] should we cache the imatrix file on disk?

[Tool] noted

[Assistant] No. The file is read once per quant run and the OS page cache already keeps it hot if you re-run shortly after.

## Tools

You have access to a set of tools to help answer the user question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:

<｜DSML｜tool_calls>
<｜DSML｜invoke name="$TOOL_NAME">
<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
...
</｜DSML｜invoke>
<｜DSML｜invoke name="$TOOL_NAME2">
...
</｜DSML｜invoke>
</｜DSML｜tool_calls>

String parameters should be specified as raw text and set `string="true"`. Preserve characters such as `>`, `&`, and `&&` exactly; never replace normal string characters with XML or HTML entity escapes. Only if a string value itself contains the exact closing parameter tag `</｜DSML｜parameter>`, write that tag as `</｜DSML｜parameter>` inside the value. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.

If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.

Otherwise, output directly after </think> with tool calls or final response.

[Assistant] It picks the index of the largest logit by linear scan from index 1 forward, starting with index 0 as the initial best. No tie-breaker beyond first-seen.

## Tools

You have access to a set of tools to help answer the user question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:

<｜DSML｜tool_calls>
<｜DSML｜invoke name="$TOOL_NAME">
<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
...
</｜DSML｜invoke>
<｜DSML｜invoke name="$TOOL_NAME2">
...
</｜DSML｜invoke>
</｜DSML｜tool_calls>

String parameters should be specified as raw text and set `string="true"`. Preserve characters such as `>`, `&`, and `&&` exactly; never replace normal string characters with XML or HTML entity escapes. Only if a string value itself contains the exact closing parameter tag `</｜DSML｜parameter>`, write that tag as `</｜DSML｜parameter>` inside the value. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.

If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.

Otherwise, output directly after </think> with tool calls or final response.

[System]
You are Swival, a coding agent with a friendly, human-like personality. You solve tasks autonomously using the tools provided, taking the optimal decisions at every step. Keep going until the task is fully complete. Do not call tools for simple math, greetings, or unclear standalone questions. For minor ambiguity, pick the most likely intent and briefly state your choice.

## Workflow

- Use tools only when needed; answer plain questions directly.
- Explore before editing: outline, list_files, grep, then read_file.
- Use think before multi-step coding tasks, debugging, choosing alternatives, and editing code.
- Use todo for multi-step work and mark items done as you finish.
- One logical change at a time. Do not re-read files after editing.
- On tool errors, use think to diagnose before retrying.

## Editing

- Copy old_string verbatim from read_file.
- For multiple matches, pass line_number. Use replace_all only when every occurrence should change.

## Safety

- Never print secrets to the console.
- Do not take any action that could degrade the workspace.

[System]
You are Swival, a coding agent with a friendly, human-like personality. You solve tasks autonomously using the tools provided, taking the optimal decisions at every step. Keep going until the task is fully complete. Do not call tools for simple math, greetings, or unclear standalone questions. For minor ambiguity, pick the most likely intent and briefly state your choice.

## Workflow

- Use tools only when needed; answer plain questions directly.
- Explore before editing: outline, list_files, grep, then read_file.
- Use think before multi-step coding tasks, debugging, choosing alternatives, and editing code.
- Use todo for multi-step work and mark items done as you finish.
- One logical change at a time. Do not re-read files after editing.
- On tool errors, use think to diagnose before retrying.

## Editing

- Copy old_string verbatim from read_file.
- For multiple matches, pass line_number. Use replace_all only when every occurrence should change.

## Safety

- Never print secrets to the console.
- Do not take any action that could degrade the workspace.

## Safety

## Tools

You have access to a set of tools to help answer the user question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:

<｜DSML｜tool_calls>
<｜DSML｜invoke name="$TOOL_NAME">
<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
...
</｜DSML｜invoke>
<｜DSML｜invoke name="$TOOL_NAME2">
...
</｜DSML｜invoke>
</｜DSML｜tool_calls>

String parameters should be specified as raw text and set `string="true"`. Preserve characters such as `>`, `&`, and `&&` exactly; never replace normal string characters with XML or HTML entity escapes. Only if a string value itself contains the exact closing parameter tag `</｜DSML｜parameter>`, write that tag as `</｜DSML｜parameter>` inside the value. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.

If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.

Otherwise, output directly after </think> with tool calls or final response.

[Assistant] The body contains a literal </｜DSML｜parameter> inside the tool output. The renderer escapes the leading character to </｜DSML｜parameter> so the model never sees a stray closing tag.

## Tools

You have access to a set of tools to help answer the user question. You can invoke tools by writing a "<｜DSML｜tool_calls>" block like the following:

<｜DSML｜tool_calls>
<｜DSML｜invoke name="$TOOL_NAME">
<｜DSML｜parameter name="$PARAMETER_NAME" string="true|false">$PARAMETER_VALUE</｜DSML｜parameter>
...
</｜DSML｜invoke>
<｜DSML｜invoke name="$TOOL_NAME2">
...
</｜DSML｜invoke>
</｜DSML｜tool_calls>

String parameters should be specified as raw text and set `string="true"`. Preserve characters such as `>`, `&`, and `&&` exactly; never replace normal string characters with XML or HTML entity escapes. Only if a string value itself contains the exact closing parameter tag `</｜DSML｜parameter>`, write that tag as `</｜DSML｜parameter>` inside the value. For all other types (numbers, booleans, arrays, objects), pass the value in JSON format and set `string="false"`.

If thinking_mode is enabled (triggered by <think>), you MUST output your complete reasoning inside <think>...</think> BEFORE any tool calls or final response.

Otherwise, output directly after </think> with tool calls or final response.
