🤖 Fix all issues with AI agents
In @.github/workflows/tests.yml:
- Around line 130-134: The CI .env creation step ("Create test environment
file") currently only writes FASTAPI_SECRET_KEY; update that step to also append
FALKORDB_URL with the proper test URL (use the same FALKORDB_URL value for the
SDK job and ensure the unit-tests step that generates the CI .env uses the
identical value) so both workflow steps produce a .env containing
FASTAPI_SECRET_KEY and FALKORDB_URL; keep the rest of the workflow (Python 3.12,
pipenv sync --dev, starting FalkorDB for tests, Playwright browser install)
unchanged.
In `@api/core/schema_loader.py`:
- Around line 230-237: The except block currently embeds raw exception text
(str(e)) into the DatabaseConnection.message which may leak credentials;
instead, update the except handler that catches (RedisError, ConnectionError,
OSError) to log the full exception (logging.exception already does this) but
return a generic error message in the DatabaseConnection (e.g., "Error
connecting to database") and preserve success=False, tables_loaded=0; reference
the DatabaseConnection construction in this except block and the exception
variable e when making the change.
- Around line 212-221: The returned DatabaseConnection currently sets
database_id to just the extracted db_name (from url.split(...)) which omits the
required user namespace; in the load_database_sync function build the namespaced
graph_id by prepending the available user_id (e.g., f"{user_id}_{db_name}") and
return that as database_id in the DatabaseConnection so callers receive the same
namespaced graph_id produced by the loaders' refresh_graph_schema methods;
update the DatabaseConnection(...) call to use the constructed namespaced id
instead of raw db_name, keeping tables_loaded, success and message the same.
In `@api/core/text2sql_sync.py`:
- Around line 199-202: The current error handling in the block checking
healing_result uses "raise exec_error", which loses the original traceback;
update the handler in the function where healing_result and exec_error are
defined (the block that currently reads if not healing_result.get("success"):
raise exec_error) to use a bare "raise" so the original exception traceback is
preserved when re-raising the caught error.
- Around line 338-345: The fire-and-forget asyncio.create_task call that invokes
ctx.memory_tool.save_query_memory (using ctx.chat.queries_history[-1] and
final_sql) can drop exceptions; update this to capture the created Task (e.g.,
task = asyncio.create_task(...)) and either await it at an appropriate point or
wrap the coroutine body in a try/except that logs exceptions via the existing
logger (or attach a done callback that logs task.exception()). Ensure you
reference the asyncio.create_task invocation and the
ctx.memory_tool.save_query_memory call when implementing the change so failures
are surfaced instead of being silently lost.
- Around line 58-60: The _graph_name function currently always prefixes graph_id
with user_id; change it to match the original behavior by returning graph_id
unchanged when it already starts with GENERAL_PREFIX, otherwise return the
namespaced f"{user_id}_{graph_id}". Update the logic in function _graph_name to
check for GENERAL_PREFIX (the same constant used in api/core/text2sql.py) and
apply the prefixing only when the graph_id does not start with that prefix.
In `@Makefile`:
- Line 71: The Makefile currently silences pylint failures with "|| true"
causing lint errors to be ignored; update the rule that runs "$(RUN_CMD) pylint
$(shell git ls-files '*.py') || true" to remove the "|| true" so pylint's
non-zero exit status fails the make target (or alternatively capture and re-exit
with the pylint status), ensuring the lint step using RUN_CMD and pylint
actually propagates failures in CI.
- Line 55: The test-unit Makefile target currently runs pytest with -k "not e2e"
but still includes SDK integration tests; update the pytest invocation in the
rule that uses $(RUN_CMD) python -m pytest tests/ to also exclude the SDK
integration directory (e.g., add an additional -k filter like 'and not test_sdk'
or use -k "not e2e and not test_sdk") so tests/test_sdk are skipped when running
the unit target; ensure you update the same command using the $(RUN_CMD)
invocation so test-unit no longer runs SDK integration tests.
In `@pyproject.toml`:
- Line 47: Replace the moving-target git ref for the graphiti-core dependency
with a specific commit SHA to ensure reproducible installs: locate the
dependency line that currently reads "graphiti-core @
git+https://github.com/FalkorDB/graphiti.git@staging" in pyproject.toml and
change the branch ref to a full commit hash (format:
git+https://...@<commit-sha>), committing the updated pyproject.toml so future
installs use that exact commit; update the SHA deliberately when you want to
pull upstream changes.
In `@queryweaver_sdk/client.py`:
- Around line 76-83: _setup_connection currently writes the FalkorDB connection
into module-global api.extensions.db which will be overwritten when multiple
QueryWeaver instances exist; change this by removing the direct assignment and
instead either (a) add an instance-level accessor on QueryWeaver that other
components call to get the connection, (b) add a registration API on
api.extensions (e.g. api.extensions.register_db(instance_id, db) and use a
per-instance key) or (c) use a context/local registry to hold the connection for
the current instance, and update callers to obtain the connection via that new
accessor/registry; if you opt not to change behavior, add documentation to the
QueryWeaver class and _setup_connection noting that only a single SDK instance
is supported and that it mutates api.extensions.db.
- Around line 99-101: The current code truncates graph_id via
graph_id.strip()[:200] then only checks for emptiness but errors claim "must be
non-empty and less than 200 characters"; fix by validating length before
truncation and return a consistent error: compute clean = graph_id.strip(), if
not clean or len(clean) > 200 then raise the appropriate error (either raise
ValueError with message "Invalid graph_id, must be non-empty and less than 200
characters." or, to match api/core/text2sql.py:_graph_name, raise
GraphNotFoundError with "Invalid graph_id, must be less than 200 characters.");
only truncate after passing validation if truncation is needed, and update the
raised exception type/message to match the chosen behavior.
In `@queryweaver_sdk/connection.py`:
- Around line 111-116: The close() method must also close internal non-pooled
FalkorDB Redis connections: before setting self._db = None, detect when
self._pool is None and self._db exists, access the internal connection via
self._db.connection and await its aclose() to release the underlying
redis.asyncio.Redis client; keep the existing pool disconnect logic for when
self._pool is not None and ensure both branches null out self._db afterwards.
In `@tests/test_sdk/conftest.py`:
- Around line 109-144: The fixture currently reads TEST_MYSQL_URL into the
variable url but then ignores it and hardcodes credentials when creating the
pymysql connection; update the fixture to parse TEST_MYSQL_URL (falling back to
the existing default) and extract host, port, user, password, and database, then
pass those parsed values into pymysql.connect instead of the hardcoded
localhost/root/root/testdb; look for the variable url and the
pymysql.connect(...) call in conftest.py and replace the hardcoded args with the
parsed components (use urllib.parse.urlparse or similar) so the fixture respects
the env var and avoids hardcoded credentials.
- Around line 147-153: The queryweaver fixture yields a QueryWeaver instance but
never closes it, leaking connections; wrap the yield in a try/finally and call
the instance cleanup method (e.g., qw.close() or await qw.aclose() if async) in
the finally block so the QueryWeaver created in the fixture (symbol:
QueryWeaver, variable: qw, fixture name: queryweaver) is properly closed after
tests complete.
- Around line 21-26: Remove the custom session-scoped event_loop fixture (the
function named event_loop) from conftest.py; this redefinition is
deprecated/removed in pytest-asyncio. Delete the event_loop fixture and instead
mark async tests with pytest.mark.asyncio(scope="session") (or
loop_scope="session" for 0.24+) or set asyncio_default_fixture_loop_scope =
"session" in pytest configuration so tests get a session-scoped loop without
redefining event_loop.
In `@tests/test_sdk/test_queryweaver.py`:
- Line 224: The assert in the test (the assertion comparing "Bob Jones" against
customer_names) uses an unnecessary f-string; change the assertion message in
the line containing assert "Bob Jones" not in customer_names to use a plain
string (remove the leading f from the message) so it reads: assert "Bob Jones"
not in customer_names, "'Bob Jones' should not be in NYC results".
- Around line 391-412: The test is calling QueryResult with flattened fields
that don't exist; instead build the nested QueryMetadata and QueryAnalysis
objects and pass them into QueryResult (e.g., create a QueryMetadata instance
for sql_query and results, and a QueryAnalysis instance for ai_response,
confidence, is_destructive, requires_confirmation, execution_time), then call
QueryResult(..., metadata=that_metadata, analysis=that_analysis) and update
assertions to read from d["metadata"] and d["analysis"] (or the dict keys
produced by QueryResult.to_dict()) to match the model's structure.
- Around line 447-465: The test calls QueryResult with a non-existent confidence
parameter; instead instantiate a QueryMetadata with the confidence value and
pass it via the QueryResult.metadata field. Update the
test_query_result_default_values to import QueryMetadata (from
queryweaver_sdk.models) and create metadata = QueryMetadata(confidence=0.8) then
construct QueryResult(sql_query="SELECT 1", results=[], ai_response="Test",
metadata=metadata) and keep the same assertions for default optional fields on
the QueryResult instance.
🧹 Nitpick comments (7)
tests/test_sdk/test_queryweaver.py (3)
85-86: Use a more specific exception type instead of bareException.Catching
Exceptionis too broad and may mask unrelated failures. Based on theInvalidArgumentErrorraised by the SDK for invalid URLs (perapi/core/schema_loader.py), use that specific exception.♻️ Proposed fix
`@pytest.mark.asyncio` async def test_connect_invalid_url(self, queryweaver): """Test connecting with invalid URL format.""" - with pytest.raises(Exception): # Should raise InvalidArgumentError + from api.core.errors import InvalidArgumentError + with pytest.raises(InvalidArgumentError): await queryweaver.connect_database("invalid://url")
266-269: Rename unused loop variablekeyto_key.The loop variable is not used within the loop body.

51-51: Unusedhas_llm_keyfixture parameter.The
has_llm_keyfixture is injected but never used in these test methods. If this is intentional (to ensure LLM key presence before running), consider adding a brief comment or usingpytest.mark.usefixtures("has_llm_key")as a class decorator instead.Also applies to: 68-68, 94-94, 143-143, 185-185, 234-234, 285-285, 336-336, 369-369

1-209: Consider adding a factory method for backward-compatible construction.The pipeline failure shows tests using
QueryResult(confidence=0.95, ...)which doesn't work with the current signature. While fixing the tests is the right approach, you could also add a@classmethodfactory for convenience if flat-kwarg construction is a common pattern.♻️ Optional factory method
`@classmethod` def from_flat( cls, sql_query: str, results: list[dict[str, Any]], ai_response: str, confidence: float = 0.0, execution_time: float = 0.0, is_valid: bool = True, is_destructive: bool = False, requires_confirmation: bool = False, missing_information: str = "", ambiguities: str = "", explanation: str = "", ) -> "QueryResult": """Create QueryResult from flat keyword arguments.""" return cls( sql_query=sql_query, results=results, ai_response=ai_response, metadata=QueryMetadata( confidence=confidence, execution_time=execution_time, is_valid=is_valid, is_destructive=is_destructive, requires_confirmation=requires_confirmation, ), analysis=QueryAnalysis( missing_information=missing_information, ambiguities=ambiguities, explanation=explanation, ), )api/core/text2sql_sync.py (2)
472-477: Uselogging.exceptionfor automatic traceback inclusion.
logging.exceptionautomatically includes the traceback when called from an exception handler.♻️ Proposed fix

181-183: Move success return outside the try block.Per Ruff TRY300, returning inside
trycan mask exceptions raised during the return statement itself.♻️ Proposed fix

Return the actual namespaced graph_id instead of extracting database name from URL.
The loader creates a namespaced graph_id in the format {user_id}_{database_name} (as shown in the loaders' refresh_graph_schema methods), but load_database_sync returns only the database name extracted from the URL. This mismatch causes SDK calls using the returned database_id to fail. Since user_id is already available in the function, construct and return the namespaced graph_id: database_id=f"{user_id}_{db_name}".

MySQL fixture ignores url and hardcodes credentials.
The fixture reads TEST_MYSQL_URL into url but then ignores it entirely, hardcoding localhost, root, root, testdb. This creates inconsistency and a potential security concern with hardcoded credentials.
🔧 Proposed fix - parse URL or use env vars consistently

Test uses incorrect constructor signature for QueryResult.
The pipeline failure indicates QueryResult.__init__() got an unexpected keyword argument 'confidence'. Per queryweaver_sdk/models.py, QueryResult accepts metadata: QueryMetadata and analysis: QueryAnalysis as nested objects, not top-level confidence, is_destructive, etc.

Pull request overview
This PR introduces a standalone Python SDK (queryweaver_sdk) that enables developers to use QueryWeaver's Text2SQL functionality programmatically without running a web server. The SDK provides async methods for connecting databases, executing natural language queries, and managing schemas through a clean dataclass-based API.
Changes:
- Adds new
queryweaver_sdkpackage withQueryWeaverclient class, connection management, and result models - Introduces non-streaming sync variants of core Text2SQL functions in
api/core/text2sql_sync.pythat return structured dataclasses - Implements modern Python packaging with
pyproject.tomlsupporting optional dependencies (SDK-only, server, dev, all) - Adds comprehensive integration test suite with docker-compose test infrastructure for FalkorDB, PostgreSQL, and MySQL
- Updates CI/CD, Makefile, and documentation to support SDK development and testing workflows

There was a problem hiding this comment.
The unit tests are filtered with -k "not e2e and not test_sdk" which means SDK tests are excluded from the unit test run. However, the new test-all target runs test-unit test-sdk test-e2e sequentially. This means the SDK tests are run separately but might overlap with unit test concerns. Consider clarifying the test taxonomy - are SDK tests integration tests, or a separate category? The filtering suggests they should be kept separate, which is sensible, but the documentation doesn't explain why.

There was a problem hiding this comment.
The exception handler only catches (RedisError, ConnectionError, OSError) but SQL execution can raise many other database-specific exceptions (e.g., psycopg2.Error, pymysql.Error, syntax errors, permission errors). Queries that fail with other exception types will propagate up uncaught rather than being healed. Consider catching a broader set of exceptions or at least documenting which error types are deliberately excluded from healing.

There was a problem hiding this comment.
The _setup_connection method directly mutates the api.extensions.db global variable. This approach creates a hidden side effect that could cause issues if multiple QueryWeaver instances are created in the same process. Each new instance will overwrite the previous connection, potentially breaking concurrent usage or causing one instance's operations to use another instance's connection. Consider refactoring the api.core functions to accept an explicit database connection parameter instead of relying on a global.

There was a problem hiding this comment.
The graph name truncation logic silently truncates to 200 characters without warning the user. If a user passes a graph_id that's longer than 200 characters, it will be silently truncated, potentially causing confusing behavior where they can't find their database later. Consider raising a ValueError for excessively long graph IDs or at least logging a warning when truncation occurs.

There was a problem hiding this comment.
The example shows importing QueryWeaver from queryweaver_sdk, but the installation instructions say to pip install queryweaver (no _sdk suffix). This inconsistency could confuse users. Verify that the package name is actually "queryweaver" (as in pyproject.toml line 6) and clarify whether users import from queryweaver or queryweaver_sdk. Based on pyproject.toml, the package includes both the queryweaver_sdk and api directories, so the import is correct, but this should be explicitly noted.

There was a problem hiding this comment.
The try/except blocks catching "Event loop is closed" RuntimeError and skipping tests indicate a fundamental issue with async test setup. These workarounds suggest the underlying problem (likely the session-scoped event loop in conftest.py) should be fixed rather than papering over the symptoms. This makes the tests flaky and unreliable.

Tests create QueryWeaver instances but never close them, leading to resource leaks. The init method calls _setup_connection() which accesses self._connection.db, triggering lazy connection initialization even for simple instantiation tests. All tests should either use the async context manager pattern async with QueryWeaver(...) as qw: or explicitly call await qw.close() in cleanup/finally blocks. This affects all test classes (TestQueryWeaverInit, TestConnectDatabase, TestGetSchema, TestQuery, TestDeleteDatabase) with approximately 15 tests leaking connections.

There was a problem hiding this comment.
The type hint uses dict[str, Any] which is Python 3.9+ syntax. However, pyproject.toml specifies requires-python = ">=3.12", so this is acceptable. For maximum clarity and consistency with the rest of the codebase, verify all type hints follow the same pattern throughout.

Great work on the SDK — the client layer is clean and tests are real integration tests, which is the right approach. Must fix before merge:

Summary
This PR introduces a standalone Python SDK (
queryweaver_sdk) that exposes QueryWeaver's Text2SQL functionality as an embeddable library. Users can now convert natural language to SQL directly in their Python applications without running a web server.Features
New SDK Package (
queryweaver_sdk/)QueryWeaverclass - Main entry point with async methods:connect_database(db_url)- Connect PostgreSQL/MySQL databasesquery(database, question)- Convert natural language to SQL and executeget_schema(database)- Retrieve database schemalist_databases()- List connected databasesdelete_database(database)- Remove database from FalkorDBrefresh_schema(database)- Re-sync schema after changesexecute_confirmed(database, sql)- Execute confirmed destructive operationsResult models (
models.py):QueryResult- SQL query, results, AI response, confirmation flagsSchemaResult- Tables (nodes) and relationships (links)DatabaseConnection- Connection status and metadataRefreshResult- Schema refresh statusConnection management (
connection.py):FalkorDBConnection- Explicit FalkorDB connection handlingUsage Example
Modern Python Packaging

Architecture
The SDK uses lazy imports for
api.*modules to allow:from queryweaver_sdk import QueryWeaverwithout FalkorDB runningQueryWeaver()instantiationCore functions in
api/core/text2sql.pyandapi/core/schema_loader.pynow have_syncvariants that return structured dataclasses instead of streaming generators.Requirements
