Important Details of Tool Functions

Dependency (dependencies) Handling

• In splitTasks and other functions, the dependencies parameter accepts task names or task IDs (UUID)
• The system converts string arrays to TaskDependency object arrays when creating or updating tasks
• Task dependencies form a directed acyclic graph (DAG), used to determine task execution order and blocking status

Task Complexity Assessment

• The system uses the assessTaskComplexity function to evaluate task complexity
• Evaluation is based on multiple metrics: description length, number of dependencies, notes length, etc.
• Complexity levels are determined based on thresholds defined in TaskComplexityThresholds
• Complexity assessment results are used to generate appropriate handling recommendations

File Processing Features

• The loadTaskRelatedFiles function does not actually read file contents, it only generates file information summaries
• Files are sorted by type priority: TO_MODIFY > REFERENCE > DEPENDENCY > CREATE > OTHER
• Supports specifying code block line number ranges for precise localization of key implementations

Utility Functions

Summary Extraction (summaryExtractor.ts)

• extractSummary - Extract short summaries from text, automatically handling Markdown format
• generateTaskSummary - Generate task completion summaries based on task names and descriptions
• extractTitle - Extract text suitable as titles from content

File Loading (fileLoader.ts)

• loadTaskRelatedFiles - Generate content summaries of task-related files
• generateFileInfo - Generate basic file information summaries

Task Memory Feature

The Task Memory feature is an important characteristic of the Shrimp Task Manager, giving the system long-term memory capabilities to save, query, and utilize past task execution experiences.

Core Implementation

1. Automatic Backup Mechanism:

   • Dual backup functionality implemented in the clearAllTasks function
   • Task backups are saved in both the data directory and the data/memory subdirectory
   • Backup files are named using timestamps, in the format tasks_memory_YYYY-MM-DDThh-mm-ss.json

2. Intelligent Prompt Guidance:

   • Task memory retrieval guidelines added to the prompt in the planTask function
   • Guides Agents on how to find, analyze, and apply historical task records
   • Provides intelligent reference suggestions, promoting knowledge reuse

Use Cases

• During Task Planning: Reference implementation plans and best practices from similar tasks
• During Problem Solving: Consult similar problems encountered in the past and their solutions
• During Code Reuse: Identify reusable components or patterns implemented in the past
• During Experience Learning: Analyze past successful and failed cases, continuously optimize working methods

Technical Points

• Use relative paths to reference the memory directory, maintaining code consistency and maintainability
• Ensure the memory directory exists, automatically creating it if it doesn't
• Maintain the original error handling pattern, ensuring system stability
• The backup process is transparent and unnoticeable, not affecting the user's normal operation flow

This feature requires no additional tools or configuration. The system automatically saves historical records when tasks are cleared and provides intelligent guidance during task planning, allowing Agents to fully utilize past experiences and knowledge.
