Summary by Sourcery

Add CI workflows for Python code quality checks and refactor the long-term memory plugin to centralize prompts, improve command validation, and use timezone-aware metadata.

New Features:

  • Introduce a GitHub Actions workflow to run Ruff linting, formatting checks, and Python syntax/metadata validation on pushes and pull requests.

Bug Fixes:

  • Update memory metadata handling to use timezone-aware UTC timestamps and more robust dict conversion.

Enhancements:

  • Extract LLM prompt templates, memory type constants, and sanitization logic into a dedicated prompts module for reuse and configurability.
  • Refine memory manager state access via new accessors and helpers for KB connection status, pending writes, and query filter construction.
  • Unify memory command validation and initialization checks to reduce duplication and ensure consistent permission and argument handling.
  • Simplify memory formatting and injection logic, including safer JSON fence stripping and standardized memory type validation.
  • Streamline memory clearing, listing, and stats retrieval by sharing filter and deletion logic.
  • Clean up metadata.yaml whitespace for consistent formatting.

Build:

  • Add a code-quality GitHub Actions workflow configuring Ruff and Python 3.11 for lint, format, syntax, and metadata checks.

CI:

  • Enable automated linting, formatting verification, syntax compilation, and metadata/schema validation on CI runs.

Chores:

  • Add a prompts.py module to centralize long-term memory prompts, constants, and sanitization helpers.

Code Review

This pull request refactors the long-term memory plugin by centralizing prompts and sanitization logic into a new module, consolidating command validation through helper functions, and improving the MemoryManager with a unified filter builder. Key feedback includes consolidating imports to remove redundancy, adding missing type hints, reconsidering the significant increase in the minimum conversation length for extraction, and replacing assertions with explicit error handling for runtime logic.

The TYPE_CHECKING block is redundant because MemoryManager is already imported at line 23. Additionally, the imports from .prompts can be consolidated into a single block for better readability and maintainability.

The default value for extraction_min_content_length has been increased from 10 to 500. This is a significant change that might cause the plugin to skip memory extraction for many valid, shorter conversations. A more moderate default like 150 might be more appropriate unless 500 is strictly required for performance or quality reasons.

Using assert for runtime logic validation is discouraged because assertions can be optimized away in production environments (e.g., when running Python with the -O flag). It is safer to use an explicit if check and raise a ValueError.

Hey - 我发现了 1 个问题,并留下了一些整体性的反馈:

  • MemoryMetadata 中,将 user_idplatform_idsender_idumouri 等标识符改为可选并使用空字符串作为默认值,可能会掩盖元数据不完整的情况;建议保持这些字段为必填(不设置默认值),或者在使用 MemoryMetadata.from_dict 的地方增加显式校验,以确保关键字段一定存在。
  • extract_memories 中将 extraction_min_content_length 的默认值从 10 调整到 500,会显著提高触发抽取的门槛;如果希望较短的对话也能产生记忆,建议使用更低的默认值,或者完全从配置中读取该阈值,而不是在代码中硬编码这么高的回退值。

**issue (bug_risk):**`store_memory` 中移除默认 URI 生成逻辑可能会导致 `None` 或重复的 URI。

在这个变更之后,像 `extract_memories` 这样的调用方现在可以将 `uri=None` 传递给 `get_documents`,而这个 `None` 将被写入元数据。这打破了之前 `store_memory` 一定会生成唯一 URI 的保证,可能导致多个记忆共享 `uri=None`,并使 URI 在像 `/memory forget` 这样的操作中变得不可用。请恢复在 `uri is None` 时生成 URI 的逻辑,或者在 API 边界强制 URI 不能为空,并相应更新所有调用方。

Hey - I've found 1 issue, and left some high level feedback:

  • In MemoryMetadata, making identifiers like user_id, platform_id, sender_id, umo, and uri optional with empty-string defaults may hide cases where metadata is incomplete; consider keeping these required (no defaults) or adding explicit validation where MemoryMetadata.from_dict is used to ensure critical fields are present.
  • The change of extraction_min_content_length default from 10 to 500 in extract_memories significantly raises the bar for when extraction runs; if shorter conversations should still produce memories, consider a lower default or reading this threshold entirely from config without hardcoding such a high fallback.

**issue (bug_risk):** Removing default URI generation in `store_memory` can lead to `None` or duplicate URIs.

With this change, callers like `extract_memories` can now pass `uri=None` through to `get_documents`, and that `None` will be written into metadata. This breaks the previous guarantee that `store_memory` always produced a unique URI, can cause multiple memories to share `uri=None`, and makes URIs unusable for operations like `/memory forget`. Please either restore URI generation when `uri is None` or enforce non-`None` URIs at the API boundary and update all callers accordingly.

  • _delete_by_filtersget_documents 异常时会继续执行 delete_documents,但 deleted = len(docs) 会固定为 0,导致返回值与日志“实际删除”不准确,并可能影响上层基于返回值的分支逻辑。建议在异常分支使用 count_documents(metadata_filter=filters) 获取删除前数量(类似 _clear_by_filters 的处理)。
