[User] what does sample_argmax do? read it

[Tool]
static int sample_argmax(const float *logits, int n) {
    int best = 0;
    float best_v = logits[0];
    for (int i = 1; i < n; i++) {
        if (logits[i] > best_v) {
            best_v = logits[i];
            best = i;
        }
    }
    return best;
}

[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.

[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

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

## 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.

- 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.

## 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.

[User] what is the difference between prefill and decode?

[Assistant] Prefill processes the prompt tokens in batched matmuls to fill the KV cache; decode then runs one token at a time using the cached state. Prefill is bandwidth-bound on large prompts; decode is dominated by per-token attention scan plus MoE routing.

[User] investigate why ds4-server logs 'shutdown requested' mid-request

[Tool]
ds4_server.c:7297:        snprintf(err, sizeof(err), "shutdown requested");
ds4_server.c:8199:    server_log(DS4_LOG_DEFAULT, "ds4-server: shutdown requested, draining requests");

[Tool]
    if (g_stop_requested && strcmp(finish, "error") != 0) {
        finish = "error";
        snprintf(err, sizeof(err), "shutdown requested");
    }

[Tool] ds4_server.c:46:    g_stop_requested = 1;

[Tool]
static void stop_signal_handler(int sig) {
    (void)sig;
    if (g_stop_requested) _exit(130);
    g_stop_requested = 1;
    ...
}

[Assistant] g_stop_requested is set only by SIGINT/SIGTERM, so the mid-request 'shutdown requested' means the process received that signal. It is not raised by an internal timeout or by a client disconnect.

[User] where do we render the tool-call preamble?

[Tool]
ds4_server.c:1646:static void append_tools_prompt_text(buf *b, const char *tool_schemas) {
ds4_server.c:1922:        append_tools_prompt_text(&system, tool_schemas);

[Assistant] It is in ds4_server.c at line 1646, called from render_chat_prompt_text at 1922.

[User] what does sample_argmax do? read it

[Tool]
static int sample_argmax(const float *logits, int n) {
    int best = 0;
    float best_v = logits[0];
    for (int i = 1; i < n; i++) {
        if (logits[i] > best_v) {
            best_v = logits[i];
            best = i;
        }
    }
    return best;
}

[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.

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.

[User] where do we render the tool-call preamble?

[Tool]
ds4_server.c:1646:static void append_tools_prompt_text(buf *b, const char *tool_schemas) {
ds4_server.c:1922:        append_tools_prompt_text(&system, tool_schemas);

[Assistant] It is in ds4_server.c at line 1646, called from render_chat_prompt_text at 1922.

[User] what does sample_argmax do? read it

[Tool]
static int sample_argmax(const float *logits, int n) {
    int best = 0;
    float best_v = logits[0];
    for (int i = 1; i < n; i++) {
        if (logits[i] > best_v) {
            best_v = logits[i];
            best = i;
        }
    }
    return best;
}

[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.

## 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.
