Secret Agents: A Self-Healing Codebase Agentic Workflow
Overview
This code implements a workflow-based error detection and correction system that combines LangGraph, LLM capabilities, and vector database technology to detect runtime errors, generate fixes, and maintain a memory of bug patterns. The system takes function definitions and runtime arguments, processes them through a graph-based workflow, and maintains a hierarchical error management system enriched by vector-based similarity search.
Motivation
Several key factors motivate this implementation:
-
Automated Error Resolution
- Manual debugging is time-consuming and error-prone
- Automated fix generation streamlines the correction process
- LLMs can provide context-aware code repairs
-
Pattern-Based Learning
- Vector databases enable similarity-based bug pattern recognition
- Previous fixes can inform future error resolution
- Semantic search capabilities improve fix relevance
-
Structured Bug Knowledge
- Vector embeddings capture semantic relationships between errors
- ChromaDB enables efficient storage and retrieval of bug patterns
- Hierarchical error categorization through vector spaces
-
Runtime Code Modification
- Safe deployment of generated fixes
- State tracking during modifications
- Validation of applied patches
Key Components
-
State Management System:
- Maintains workflow state using Pydantic models
- Tracks function references, errors, and fixes
- Ensures type safety and execution validation
-
LLM Integration:
- Leverages LLM for code analysis and generation
- Produces fixes based on error types:
- Runtime Errors
- Logic Errors
- Type Errors
- Resource Errors
-
Vector-Based Memory System:
- Uses ChromaDB for efficient storage
- Enables semantic search of bug patterns
- Maintains contextual relationships between errors
- Supports pattern-based learning
-
Graph-based Workflow:
- Uses LangGraph's StateGraph for orchestration
- Implements error detection nodes
- Controls fix generation through edges
Vector Databases and ChromaDB
What is a Vector Database?
A vector database is specialized storage system designed to handle high-dimensional vectors, which are mathematical representations of data points. These vectors capture semantic meaning, making them ideal for:
- Similarity search operations
- Pattern recognition
- Semantic relationships
- Nearest neighbor queries
Why Vector DBs Matter for ML
Vector databases are crucial for modern ML systems because they:
- Enable semantic search capabilities
- Support efficient similarity computations
- Scale well with large datasets
- Maintain context and relationships
- Facilitate pattern recognition
ChromaDB Implementation
ChromaDB provides a lightweight, embedded vector database that offers:
- Simple API:
chroma_client = chromadb.Client()
collection = chroma_client.create_collection(name='bug-reports')- Easy Data Management:
# Adding documents
collection.add(
ids=[id],
documents=[document],
)
# Querying
results = collection.query(
query_texts=[query],
n_results=10
)- Automatic embedding generation
- Efficient similarity search
- Zero configuration requirements
Memory Architecture
The system implements a sophisticated memory architecture:
-
Vector Storage:
- Bug reports converted to embeddings
- Semantic relationships preserved
- Efficient similarity search
-
Pattern Recognition:
- Similar bugs identified through vector similarity
- Historical fixes inform new solutions
- Pattern evolution tracked over time
-
Memory Updates:
- New patterns integrated into existing knowledge
- Related patterns merged and refined
- Obsolete patterns pruned

Conclusion
This implementation demonstrates a practical approach to automated code healing, enhanced by vector database technology. The system combines graph-based workflow management with LLM capabilities and vector-based pattern recognition, allowing for structured error correction while maintaining clear process control.
Key advantages include:
- Automated error detection and correction
- Semantic pattern recognition
- Efficient similarity-based search
- Safe runtime code modification
Future improvements could focus on:
- Enhanced embedding strategies
- Multi-modal pattern recognition
- Distributed vector storage
- Advanced pattern evolution tracking
This system provides a foundation for building more sophisticated self-healing systems, particularly in applications requiring runtime error correction and pattern learning, with the added benefit of efficient vector-based memory management through ChromaDB.

❌ Function Raised an Error: division by zero
📝 Generating Bug Report
------------------------
**Bug Report**
**Function Name:** `divide_two_numbers`
**Description:** The function attempts to divide two numbers, `a` and `b`. However, it raises a `ZeroDivisionError` when `b` is zero.
**Error Message:** `division by zero`
**Steps to Reproduce:**
1. Call the function with any number for `a`.
2. Pass `0` as the value for `b`.
**Example:**
```python
divide_two_numbers(10, 0) # Raises ZeroDivisionError
```
**Expected Behavior:** The function should handle the case where `b` is zero and return a user-friendly error message or a default value instead of raising an exception.
**Proposed Solution:** Implement error handling to check if `b` is zero before performing the division. Return an appropriate message or value in such cases.
**Priority:** High

📝 Generating Bug Report
------------------------
**Bug Report: Division Function Error**
**Function:** `divide_two_numbers(a, b)`
**Error Raised:** `unsupported operand type(s) for /: 'str' and 'int'`
**Description:** The function `divide_two_numbers` fails to handle cases where the first argument `a` is of type `str` while the second argument `b` is of type `int`. This leads to a TypeError when attempting to perform division.
**Steps to Reproduce:**
1. Call the function with a string as the first argument and an integer as the second argument.
Example: `divide_two_numbers("10", 2)`
**Expected Behavior:** The function should either handle the type mismatch gracefully (e.g., by raising a custom error or converting input types) or document the expected input types clearly.
**Actual Behavior:** The function raises a TypeError, disrupting execution.
**Suggested Fix:** Implement input type validation to ensure both arguments are numeric (int or float) before performing the division. Alternatively, consider converting input types as needed.
**Priority:** Medium

Bug Report:
**Function Name:** process_list
**Parameters:** lst (list), index (int)
**Error Raised:** IndexError: list index out of range
**Description:** The function attempts to access an element at a specified index in the list `lst`, but if the index is greater than or equal to the length of the list or if the list is empty, it raises an "IndexError".
**Reproduction Steps:**
1. Call `process_list([], 0)`
2. Call `process_list([1, 2, 3], 5)`
**Expected Behavior:** The function should handle invalid indices gracefully, possibly by returning a default value or raising a custom error message.
**Priority:** High - this bug can lead to runtime errors when the function is used with invalid inputs.
**Proposed Solution:** Implement index validation before accessing the list element.

------------------------
**Bug Report:**
**Function:** `process_list(lst, index)`
**Error Raised:** `'NoneType' object is not subscriptable`
**Description:** The function attempts to access an element of `lst` using the provided `index`. If `lst` is `None`, this results in a TypeError since `NoneType` does not support indexing.
**Steps to Reproduce:**
1. Call `process_list(None, 0)`.
2. Observe the error message.
**Expected Behavior:** The function should handle cases where `lst` is `None` gracefully, either by returning a default value or raising a more informative error.
**Proposed Fix:** Add a check at the beginning of the function to ensure `lst` is not `None`. For example:

**Bug Report: parse_date Function**
**Function Name:** parse_date
**Error Raised:** ValueError: not enough values to unpack (expected 3, got 1)
**Description:** The function attempts to split the input string `date_string` by the '-' character and unpack the result into three variables: year, month, and day. However, if the input string does not contain two '-' characters, it raises a ValueError due to insufficient values for unpacking.
**Reproduction Steps:**
1. Call `parse_date("2023")` or any string that does not contain exactly two '-' characters.
2. Observe the error message indicating that not enough values were provided for unpacking.
**Expected Behavior:** The function should handle cases where the input does not conform to the expected format, either by returning an error message or raising a custom exception.
**Suggested Fix:** Implement input validation to ensure the `date_string` contains the correct format (YYYY-MM-DD) before attempting to unpack the values.

**Bug Report: Invalid Input Handling in parse_date Function**
**Function:** `parse_date(date_string)`
**Error Encountered:** `ValueError: invalid literal for int() with base 10: 'abc'`
**Description:** The function `parse_date` is designed to parse a date string in the format `YYYY-MM-DD`. However, it does not handle invalid input properly. When provided with a date string that contains non-numeric characters (e.g., 'abc' instead of valid year, month, or day values), the function raises a `ValueError` when attempting to convert the string to an integer.
**Steps to Reproduce:**
1. Call `parse_date('abc-def-ghi')`
2. Observe the error raised.
**Expected Behavior:** The function should validate the input string and handle errors gracefully, either by raising a custom error or returning a specific message indicating the issue with the input format.
**Proposed Solution:** Implement input validation to check if the split components of the date string are numeric before converting them to integers. If the input is invalid, return an informative error message.
**Priority:** High, as this affects the function's usability with invalid inputs.
