Memory Manager

External persistent memory system for maintaining knowledge across autonomous coding sessions.

Quick Start

Store a Memory

from scripts.memory_manager import MemoryManager

memory = MemoryManager(project_dir)
memory.store(
    key="auth_solution",
    value="Added User-Agent header to fix 403",
    memory_type="causal"
)

Store Causal Chain (Error→Solution)

memory.store_causal_chain(
    error="403 Forbidden on API call",
    solution="Add User-Agent header to requests"
)

Retrieve Similar Errors

solutions = memory.get_similar_errors("403 error calling API")
# Returns: [{"error": "403 Forbidden...", "solution": "Add User-Agent..."}]

Causal Memory Pattern

# Traditional error handling:
# Error occurs → Unclear response

# Causal memory:
# Error: 403 Forbidden
# Memory: [403] → [missing User-Agent] → [added header] → [success]
# Response: "Adding User-Agent header (learned from previous error)"

Integration Points

error-recoverer: Uses causal memory for self-healing
context-compactor: Stores summaries in episodic memory
coding-agent: Stores procedural patterns
