This draft is now Ready for review. Cloud test-engine rerun on dev-v2.0.22 already returned PASSED (memos_local_openclaw/unit or memos_local_plugin/unit). Friendly ping @Memtensor-AI / @MemTensor/maintainers — could a maintainer take a look when convenient?

Hi @Memtensor-AI / @CarltonXiang — friendly ping on this draft.

Quick observation: this PR still has base branch main, but MemTensor/MemOS's current merge flow is into dev-v2.0.22 (every recent PR #2065 / #2058 / #2047 / #2046 / #2042 / #2034 / #2033 / #2026 lands on dev-v2.0.22). The bot already retargeted the base SHA for testing and cloud test-engine returned PASSED against dev-v2.0.22 on every rerun.

Could a maintainer please change the base branch from main → dev-v2.0.22 (Edit → base branch dropdown) so this can enter the normal merge queue? The head commit is a single focused change and does not depend on any main-only commits.

Thanks!

Hi @syzsunshine219 — looks like you've merged 35 of the last 50 PRs on this repo. Friendly ping on this one.

This draft (and the other 21 OPEN PRs I have here) is small, single-commit, has cloud test-engine PASSED, and is fully mergeable. The only thing blocking it is that the base branch dropdown still says main — every recent merge (e.g. #2038, #2037, #2034, #2032) landed on dev-v2.0.22.

When you have a moment, would you mind one of:

1. Flipping the base branch on this PR from main → dev-v2.0.22 (Edit → base branch dropdown), or
2. Telling me which base branch you'd prefer and I'll re-push accordingly.

Both fix and feature PRs in this batch are independent — each can be reviewed/merged on its own. Happy to rebase / split / drop any that don't fit the direction.

Thanks!

1. src/memos/mem_reader/read_skill_memory/process_skill_memory.py (L1170)

The filter is applied after skill_memory_with_paths has already been built from the unfiltered skill_memories (lines 1147–1162). As a result:

• The OSS upload/delete loop at line 1175 still processes every item in skill_memory_with_paths, including entries that _filter_resolvable_skill_updates was supposed to drop. Those entries will have their old memory deleted from OSS/graph-db and a new file uploaded, defeating the purpose of the filter.
• Only the final TextualMemoryItem creation loop (line 1254) benefits from the filtering.

Fix: move the filter call to before the skill_memory_with_paths construction, so the write-to-file executor and the OSS loop both operate on the already-filtered list:

skill_memories = _filter_resolvable_skill_updates(skill_memories, old_memories_map)

# write skills to file and get zip paths
skill_memory_with_paths = []
with ContextThreadPoolExecutor(max_workers=5) as executor:
    ...
