Feat: Add memory editing API endpoint, MCP tool, and memory IDs in prompts #47

abrookins · 2025-08-13T00:52:04Z

Summary

Add API endpoint and MCP tool for editing existing long-term memories
Include memory IDs in memory prompts so LLMs can edit memories by ID
Support partial updates with validation and error handling

Changes Made

1. New Long-term Memory Functions (`long_term_memory.py`)

get_long_term_memory_by_id(memory_id) - Retrieve memory by ID
update_long_term_memory(memory_id, updates) - Update memory with field validation

2. New Pydantic Model (`models.py`)

EditMemoryRecordRequest - Model for partial memory updates
Supports updating: text, topics, entities, memory_type, namespace, user_id, session_id, event_date

3. New REST API Endpoints (`api.py`)

GET /v1/long-term-memory/{memory_id} - Get memory by ID
PATCH /v1/long-term-memory/{memory_id} - Update memory by ID
Proper error handling (404 for not found, 400 for validation errors)

4. New MCP Tools (`mcp.py`)

get_long_term_memory(memory_id) - Retrieve memory by ID
edit_long_term_memory(memory_id, **updates) - Update memory fields
Comprehensive documentation with usage examples

5. Enhanced Memory Prompts (`api.py`)

Memory prompts now include IDs: - {memory.text} (ID: {memory.id})
LLMs can use these IDs to call the edit tool for corrections/updates

Key Features

✅ Partial field updates with validation
✅ Automatic hash regeneration when text is updated
✅ Audit trail with updated_at timestamps
✅ Consistent error handling
✅ Full MCP tool documentation with examples
✅ Memory IDs in prompts enable LLM editing capability

Test plan

Code imports successfully
New model validates correctly
Linting and formatting passes

Why is this in utils/recency.py -- don't we use memory hashes in other places than recency queries?

Agree, we need a new adapter interface method. It can use search as a fallback if the implementation lacks a get_memory_by_id method.

@justin-cechmanek Let's discuss next week!

Task worker tests were failing because they mocked settings.redis_url but the task_worker CLI command calls get_redis_conn() directly which uses the actual Redis connection. Added proper mocks for get_redis_conn and ensure_search_index_exists to match the pattern used by other CLI tests. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

The broad exception handling with 'noqa: BLE001' suppresses the bare except warning, but this catches all exceptions including system errors. Consider catching more specific exceptions or at least logging the exception type for debugging.

The mock detection logic using string inspection is fragile and could break if the mock implementation changes. Consider using a more robust approach like checking for specific mock attributes or using a configuration flag.

I'm with Copilot on this one. I prefer type checking over string comparison

The mock detection logic imports unittest.mock in production code, which is unusual. Consider using a configuration parameter or feature flag to control this fallback behavior instead of runtime mock detection.

Broad exception handling suppresses all errors. In an interactive CLI application, it's better to catch specific exceptions like ValueError for parsing errors, or FileNotFoundError for file operations.

+        1. User: "I was promoted today"
+           - Call get_current_datetime → use `iso_utc` to set `event_date`
+           - Update text to include a grounded, human-readable date
+             (e.g., "Alice was promoted to Principal Engineer on August 14, 2025.")


If this doc string is part of the tool definition for agents should the example be "User was promoted..." instead of "Alice was promoted..."? Not sure how much it matters, just saw the defined memory modification rules elsewhere

Good catch! Yes, this is LLM-facing. And yeah, these memories perform better without attaching the user's name, so elsewhere we direct it to use "User ..." instead of the name. I'll fix!
