Module tool_types 

Shared runtime types for the VT Code tool system.

This module provides types shared between the LLM and tools subsystems, breaking the circular dependency that would otherwise exist between them.

Overview

The key types here are:

• CompactStr - stack-allocated string for short tool names
• EnhancedToolResult - tool result with quality metadata
• ResultMetadata - quality/confidence scoring for tool results
• [ToolResultConstants] - tool name constants used across subsystems

Modules

tool_names

Canonical tool name constants used by both LLM and tools subsystems. These match the values defined in vtcode-config::constants::tools.

Structs

EnhancedToolResult

Enhanced tool result with metadata

ResultMetadata

Quality metadata for tool results

Enums

ResultCompleteness

Result completeness level

Constants

DEFAULT_HASHMAP_CAPACITY

DEFAULT_STRING_CAPACITY

DEFAULT_VEC_CAPACITY

Default capacity hints for common collections

ERROR_DETECTION_PATTERNS

Standard error patterns used for error detection across tools

MAX_CONTEXT_LINES

MAX_FILE_SIZE_FOR_PROCESSING

Common tool operation limits

MAX_LIST_ITEMS_SUMMARY

MAX_OUTPUT_TOKENS

MAX_SEARCH_RESULTS

Context optimization constants following AGENTS.md guidelines

NETWORK_ERROR_PATTERNS

Network-related error patterns for more specific error detection

OVERFLOW_INDICATOR_PREFIX

OVERFLOW_INDICATOR_SUFFIX

Traits

ResultScorer

Trait for scoring tool results

Functions

canonical_tool_name

Use direct tool name without alias resolution. Alias resolution is now handled by the tool registry inventory which maintains a mapping of aliases to canonical tool names.

empty_object_schema

Reusable empty JSON object schema {"type": "object"} for tool parameter definitions. Used by tools that accept no parameters or only optional parameters.

Type Aliases

CompactStr

Compact inline string – stack-allocated for strings up to 24 bytes. Drop-in replacement for String with zero heap allocation for short strings.
