Fix #34: memos add 写入成功但 list/get 查不到：user_id 作用域在写入侧被静默丢弃

[Memtensor-AI]

Description

Fixed the user_id scope asymmetry reported in issue #34, where memos add would report success but the appended memory could not be read back by memos get / memos list / memos search.

Root cause: the write path silently dropped a resolved user_id. MemoryAPI.add_memory built its POST /add/message body by iterating common fields and only including values that were not None, so when config.defaults.user_id was None (config explicitly nulled it, or init-time default backfill was missing) and no --user-id flag was passed, the memory was stored with no user scope. Every read path, by contrast, resolves and requires a user_id (get_memories even raises APIError("Get memory requires user_id") when missing). An unscoped record is therefore never returned by a scoped lookup, and it persists after logout/login.

Changes:

• memory_api.py — add_memory now requires a non-empty user_id and always includes it in the request body; it raises APIError("Add memory requires user_id") instead of writing an unscoped memory. search_memories scope checks switched from truthiness to is not None for user_id/conversation_id/agent_id/app_id so empty-string scopes are handled consistently with add/get.
• memory_cmd.py — cmd_get takes a command_name parameter (default get) so the agent-mode envelope can label the alias correctly.
• memory.py — added a list command that delegates to cmd_get with command_name="list".
• main.py — registered list (with explicit name="list" to avoid Typer inferring None from the built-in-shadowing callback name) and added it to the help ordering.
• MemOS CLI.md — noted that memos list is an alias of memos get.
• tests/test_memory_scope.py — 8 new regression tests.

Test results: the full suite passes (49 tests OK, up from 41). Pre-existing tests that initially appeared failing were environment/import errors resolved by pip install -e .; after installation the whole suite is green. There is no configured linter in this repo, so validation used python -m py_compile on all changed modules (passed) plus the unittest suite. CLI smoke test confirmed memos list is now discoverable: memos --help lists list List memories for a user (alias for get) and memos list --help exits 0.

Outputs: opsp artifacts (task file + proposal/spec/design/verification-report) were written in the working repo and archived to the specs repo at 2026-08-25-34-memos-add-写入成功但-listget-查不到userid-作用域在写入侧被静默丢弃/.

1. src/memos_cli/backend/memory_api.py (L150-L151)

The add_memory validation uses a falsy check (if not user_id), which rejects "", but the chat method was updated to use is not None, which accepts "" and would forward an empty string as user_id to the API. This is inconsistent with add_memory and can silently reproduce the invisible-scope bug this change is meant to fix. The comment on this line claims these are the "same scoping rules as add_memory", which is incorrect.

Suggestion: either add an explicit empty-string guard in the chat path (if kwargs.get("user_id") not in (None, ""):), or align add_memory to use is None and add a separate explicit empty-string validation so both sides enforce the same contract.

💡 Suggested Change

Before:

        if kwargs.get("user_id") is not None:
            payload["user_id"] = kwargs["user_id"]

After:

        if kwargs.get("user_id") not in (None, ""):
            payload["user_id"] = kwargs["user_id"]

2. tests/test_memory_scope.py (L119-L120)

registered_commands is an undocumented internal attribute of typer.Typer, not part of Typer's public API. It may be absent or renamed in other Typer versions, causing this test to raise AttributeError instead of a meaningful assertion failure.

A more stable approach is to invoke the CLI through Typer's CliRunner (from typer.testing) and confirm the list command is reachable, or to check the registered command names via the Click group's commands dict — which is part of Click's stable public API:

from typer.testing import CliRunner
runner = CliRunner()
result = runner.invoke(main.app, ["list", "--help"])
self.assertEqual(result.exit_code, 0)

or:

click_group = typer.main.get_command(main.app)
self.assertIn("list", click_group.commands)

💡 Suggested Change

Before:

        command_names = {cmd.name for cmd in main.app.registered_commands}
        self.assertIn("list", command_names)

After:

        from typer.testing import CliRunner
        runner = CliRunner()
        result = runner.invoke(main.app, ["list", "--help"])
        self.assertEqual(result.exit_code, 0)

3. src/memos_cli/main.py (L17)

Importing list from memos_cli.commands.memory shadows Python's built-in list type. This breaks the type annotation on line 67 (-> list[str]), which now refers to the command function instead of the built-in collection type, causing a TypeError at runtime when the annotation is evaluated.

Rename the imported command to avoid the collision, for example:

from memos_cli.commands.memory import (
    add, extract, feedback, rerank, search, chat,
    get, list as list_cmd, delete, origin
)

Then register it with the explicit CLI name to preserve the user-facing command name:

app.command(name="list", rich_help_panel="Memory Operations")(list_cmd)

And update the HELP_COMMAND_ORDER list construction at line 67 to keep using the built-in list type.

💡 Suggested Change

Before:

from memos_cli.commands.memory import add, extract, feedback, rerank, search, chat, get, list, delete, origin

After:

from memos_cli.commands.memory import add, extract, feedback, rerank, search, chat, get, list as list_cmd, delete, origin
