Detailed Description¶

LLM-driven tool-call node. Constructs a tool-call prompt, runs sampling, parses the result.

Public Attributes Documentation¶

variable AcknowledgeText¶

FString UTryllToolCallParams::AcknowledgeText;

variable ContextSize¶

int32 UTryllToolCallParams::ContextSize;

KV-cache / context window (n_ctx) for this node in tokens. 0 = fall back to the model variant's context_size, else the server default_n_ctx. Validated against the model's trained maximum at agent creation.

variable Disposition¶

ETryllToolCallDisposition UTryllToolCallParams::Disposition;

End-to-end notify / pause / history policy for this node. See Tryll.ToolCallDisposition. Mutable: stamped onto ToolCallRecord at write time, so a mid-session change only affects subsequent turns.

variable Input¶

FTryllSlotInput UTryllToolCallParams::Input;

Upstream inter-node slot this field consumes. Empty = context default.

variable Mode¶

ETryllToolCallMode UTryllToolCallParams::Mode;

Tool-choice policy — see Tryll.ToolCallMode. Mutable: the grammar is rebuilt every turn, so a client can flip a node between (for example) RequireCall for a known-command turn and DetectOnly for free chat.

variable ModelName¶

FTryllModelName UTryllToolCallParams::ModelName;

variable NoToolCalledExit¶

FString UTryllToolCallParams::NoToolCalledExit;

Exit taken when no tool call is parsed (or, under mode=call_or_answer, when the model's residual text was emitted as a plain-text reply instead). Empty string = END. Graph exit "no_tool_called" — target node name; empty = END.

variable Sampling¶

FTryllSamplingOverrides UTryllToolCallParams::Sampling;

Sparse sampling overrides.

variable SystemPrompt¶

FString UTryllToolCallParams::SystemPrompt;

variable ToolCallFormat¶

FString UTryllToolCallParams::ToolCallFormat;

variable ToolCalledExit¶

FString UTryllToolCallParams::ToolCalledExit;

Exit taken when one or more tool calls are parsed from the response. Empty string = END. Graph exit "tool_called" — target node name; empty = END.

variable Tools¶

TArray<FTryllToolDefinition> UTryllToolCallParams::Tools;

Callable tool definitions. Structural because the tool-call prompt schema and parser contract are materialised at construction.

variable bOverrideAcknowledgeText¶

bool UTryllToolCallParams::bOverrideAcknowledgeText;

Result text used when disposition synthesises an acknowledgement (Acknowledge / NotifyAndAcknowledge / PauseAndAcknowledge). Empty = "ok". Ignored for RouteOnly / Notify / Pause / AwaitResult. Set to true to override the inherited AcknowledgeText value.

variable bOverrideInput¶

bool UTryllToolCallParams::bOverrideInput;

Slot name this node consumes as its primary text. Empty = "user_message". Structural: immutable after creation — rebinding would re-wire the slot dataflow that is validated once at agent creation. Set to true to override the inherited Input value.

variable bOverrideModelName¶

bool UTryllToolCallParams::bOverrideModelName;

Model catalog name. Empty = use the agent's default_model_name. Set to true to override the inherited ModelName value.

variable bOverrideSystemPrompt¶

bool UTryllToolCallParams::bOverrideSystemPrompt;

Prepended before the user turn during projection. Set to true to override the inherited SystemPrompt value.

variable bOverrideToolCallFormat¶

bool UTryllToolCallParams::bOverrideToolCallFormat;

DEPRECATED (kept for wire/config compatibility; ignored by the server). Tool-call prompting and parsing are now driven by the model's own chat template via llama.cpp common/ (see LlamaCppChatTurn), so no per-dialect format is needed. Structural so mutation is still vetoed. Set to true to override the inherited ToolCallFormat value.

variable bParallelToolCalls¶

bool UTryllToolCallParams::bParallelToolCalls;

Allow more than one tool call per turn where the model's chat template supports it (most formats cap at one call when false). Mutable for the same reason as mode.
