WalkthroughThe diff removes the ParametrizedFunction abstraction and replaces usages with Haiway's Function type, moving parameter metadata to keyword-argument-centric structures (_keyword_arguments). DataModel metaclass and validation were reworked to introduce ALLOWED_FIELDS and stricter alias handling. ResourceTemplate and FunctionTool were updated to use Function and to resolve/coerce parameters from keyword arguments and aliases. Evaluator suite JSON persistence now uses AttributesJSONEncoder. Tests related to the old parameter/validator system were removed, new tests for resource-template resolution and evaluation-suite datetime serialization were added, http response body access was made awaitable, and the haiway dependency was bumped.

72-87: Critical bug: Variadic keyword validation overwrites validated parameters.When
_variadic_keyword_parametersis not None, the second loop (lines 82-86) iterates over ALL kwargs and validates them using the variadic validator. This overwrites the correctly validated values from the first loop (lines 78-80).For example, if a function has
x: intand**kwargs: str:
- Lines 78-80:
validated['x'] = 42(validated as int)- Lines 82-86:
validated['x'] = '42'(validated as str, overwriting the int)Apply this diff to only validate extra kwargs:
else: for parameter in self._keyword_parameters.values(): with ValidationContext.scope(f".{parameter.name}"): validated[parameter.name] = parameter.validate_from(kwargs) for key, value in kwargs.items(): + if key not in self._keyword_parameters: with ValidationContext.scope(f".{key}"): validated[key] = self._variadic_keyword_parameters.validate( value, )

94-94: LGTM! Consistent with parameter model refactoring.The change from
self._parameters.values()toself._keyword_parameters.values()correctly aligns with the broader refactoring that separates parameters into explicit keyword/positional/variadic structures.src/draive/resources/template.py (1)
60-60: LGTM! Parameter references updated consistently.All three references from
self._parameterstoself._keyword_parametersare consistent with the broader parameter model refactoring that introduces separate keyword/positional/variadic parameter structures.Also applies to: 111-111, 365-365

31-35: LGTM! Clear parameter structure separation.The explicit separation into
_keyword_parameters,_positional_parameters, and variadic parameter fields provides better clarity than the previous unified_parameterscollection.
64-64: LGTM! Arguments property updated correctly.The property now returns values from
_keyword_parametersinstead of the removed_parameters, maintaining the same interface while using the new internal structure.

98-117: Replace assertions with explicit errors for alias/name uniqueness.These assertions validate critical invariants during metaclass construction but will be skipped when Python runs with optimizations (
-Oflag). Duplicate names or aliases would silently overwrite previous values, causing data loss.- assert key not in allowed_fields # nosec: B101 + if key in allowed_fields: + raise TypeError(f"Duplicate field name '{key}' in {name}") allowed_fields.add(key) if attribute.alias: - assert attribute.alias not in allowed_fields # nosec: B101 + if attribute.alias in allowed_fields: + raise TypeError(f"Alias '{attribute.alias}' conflicts with existing field in {name}") allowed_fields.add(attribute.alias) fields.append(field) if field.alias is not None: - assert field.alias not in specification_fields # nosec: B101 - assert field.name not in specification_fields # nosec: B101 + if field.alias in specification_fields: + raise TypeError(f"Duplicate alias '{field.alias}' in specification for {name}") + if field.name in specification_fields: + raise TypeError(f"Duplicate field name '{field.name}' in specification for {name}") specification_fields[field.alias] = specification else: - assert field.name not in specification_fields # nosec: B101 + if field.name in specification_fields: + raise TypeError(f"Duplicate field name '{field.name}' in specification for {name}")src/draive/resources/template.py (2)
113-126: Review validation logic and parameter handling.Several concerns:
- Line 113 uses
assertfor validation (same issue as lines 55-56).- Lines 114-120 compute
provided_namesby checking ifparameter.nameorparameter.aliasis inv_kwargs, butvalidate_argumentstypically returns validated kwargs with canonical parameter names. If an argument was passed by alias in the original kwargs, it may not appear by alias inv_kwargs.- Line 126 calls the parent with original
argsandkwargs, notv_kwargs. This seems inconsistent with line 114 where arguments are validated. Why validate if the original values are used?Consider:
- Replacing the assertion with proper exception handling
- Verifying whether
v_kwargspreserves aliases or uses canonical names- Clarifying why validation is performed but original kwargs are passed to the function
366-396: Critical: Duplicate argument error when using aliased parameters.Lines 392-394 set both
argument.nameandargument.aliasin thecoerceddictionary. When this dictionary is unpacked as**call_kwargsinresolve_from_uri(line 577), Python raises a duplicate argument error if an argument has an alias. The pipeline failure confirms this with the 'lang' parameter.Apply this diff to fix the issue by only setting the canonical parameter name:
converted: Any = self._coerce_parameter_value(argument, raw_value) coerced[argument.name] = converted - if argument.alias: - coerced[argument.alias] = convertedAlternatively, if the function expects arguments by alias rather than by name, set only the alias:
converted: Any = self._coerce_parameter_value(argument, raw_value) - coerced[argument.name] = converted - if argument.alias: - coerced[argument.alias] = converted + # Use alias if present, otherwise use name + key = argument.alias if argument.alias else argument.name + coerced[key] = convertedHowever, the first solution (using only
argument.name) is likely correct since Function types typically use canonical parameter names internally.

27-27: LGTM! Dependency bump aligns with new feature usage.The haiway version bump to 0.39.1 is required for the new
AttributesJSONEncoderandFunctionbase class used throughout this PR.src/draive/evaluation/suite.py (1)
949-954: LGTM! Custom encoder enables datetime serialization.Using
AttributesJSONEncoderallows proper JSON serialization of datetime objects and other complex types that the standard encoder cannot handle. This aligns with the new test case validating ISO-formatted datetime output.src/draive/mcp/server.py (1)
164-189: LGTM! Updated to use newhas_argsproperty.The change from checking
resource.argumentstoresource.has_argsaligns with the updatedResourceTemplateAPI. As shown in the relevant snippet fromsrc/draive/resources/template.py,has_argsreturns whether a match pattern exists, which correctly determines if the template should be exposed as anMCPResourceTemplateor a plainMCPResource.tests/test_evaluation_suite_serialization.py (1)
1-41: LGTM! Well-structured test for datetime serialization.The test properly validates that
datetimefields are serialized to ISO format when persisting evaluator suite cases. Good use oftmp_pathfixture for isolation and clear assertion on the expected format.src/draive/models/tools/function.py (2)
30-30: LGTM! Inheritance updated to use haiway'sFunction.The change from
ParametrizedFunctiontoFunction[Args, Coroutine[None, None, Result]]aligns with the broader refactoring in this PR. TheFunctionbase class from haiway provides the necessary_keyword_arguments,_positional_arguments, and related attributes used throughout.
93-113: LGTM! Parameter specification building updated correctly.The iteration over
self._keyword_arguments.values()and use ofargument.alias or argument.namefor property keys maintains correct behavior while aligning with the newFunctionbase class structure.src/draive/parameters/model.py (4)
58-58: New__ALLOWED_FIELDS__attribute enables stricter validation.This frozenset tracks all valid attribute names (including aliases), enabling O(1) lookup during validation. Good addition for enforcing allowed keys in mappings.
325-343: LGTM! Enhanced validation with allowed field checking.The validation now correctly:
- Checks for unexpected keys against
__ALLOWED_FIELDS__- Detects ambiguous inputs where both field name and alias are provided
- Preserves permissive behavior for dynamic (non-slot) models
Clear error messages include the class name for debugging.
456-463: LGTM! Per-field validation in__init__for slot-based models.The new initialization path uses
ValidationContext.scopefor detailed error paths andfield.validate_from(kwargs)for proper type validation. This maintains the frozen/immutable semantics while enabling stricter type checking.
157-166: LGTM! Instance check now validates all fields explicitly.The change from exception-based validation to explicit field iteration using
field.annotation.check()is cleaner and provides consistent behavior across parameterized and non-parameterized types.src/draive/parameters/__init__.py (1)
1-3: Based on my verification, I can now provide the rewritten review comment:
ParametrizedFunctionis not present in the codebase and verification finds no impact.The class
ParametrizedFunctiondoes not exist anywhere in the repository and is not imported fromdraive.parametersby any internal code. The removal from__all__reflects the current state of the codebase rather than introducing a breaking change. External consumers importing this symbol would have already encountered issues; this export change simply formalizes what is already the case.src/draive/resources/http.py (1)
40-46: Based on my investigation, I've found that haiway 0.39.1 does not exist on PyPI. The latest published version is 0.38.1 (released November 17, 2025). This means the API change cannot be verified against public documentation since the target version is not yet released.Here's what I found:
pyproject.tomlspecifieshaiway~=0.39.1as a dependency- PyPI shows only version 0.38.1 as the latest published release
- The code change from
response.body(property) toawait response.body()(async method) is isolated to a single location in the codebase- No public GitHub releases or documentation for version 0.39.1 are available
The API change in the code aligns with the version constraint in the project, but verification against public sources is impossible since haiway 0.39.1 hasn't been released yet. This appears to be anticipatory code for an upcoming haiway release or code in a development branch.
Verify compatibility with unreleased haiway 0.39.1. The project depends on
haiway~=0.39.1, which does not exist on PyPI (latest is 0.38.1). The code change fromresponse.bodytoawait response.body()cannot be verified against public documentation. Confirm this version is available in your environment or that the dependency version is correct.src/draive/resources/template.py (3)
59-65: LGTM!The parameter verification logic correctly uses
_keyword_argumentsto validate that URI template parameters are defined in the function signature.
104-106: LGTM!The
has_argsproperty provides a convenient way to check if the template contains parameters.
7-7: Yes, please search GitHub for the miquido/haiway Function class implementation to verify it supports the_keyword_argumentsand related metadata attributes used in template.py.

89-90: Missing assertion for variadic keyword arguments.Line 90 checks
_variadic_positional_argumentsbut there's no corresponding check for_variadic_keyword_arguments. Based on the past review comment, the original code had three assertions including one for variadic keyword arguments.assert all(arg.name in self._keyword_arguments for arg in self._positional_arguments) # nosec: B101 assert self._variadic_positional_arguments is None # nosec: B101 + assert self._variadic_keyword_arguments is None # nosec: B101Additionally, as noted in a past review, consider replacing these assertions with explicit
TypeErrorexceptions for better error messages.src/draive/resources/template.py (1)
55-56: Avoid usingassertfor argument-shape validation in__init__(same concern as earlier review)Relying on
asserthere means these checks disappear underpython -O, and failures show up later as obscure errors. This mirrors the earlier review feedback on these lines.Prefer explicit runtime checks with clear exceptions, e.g.:
- assert all(arg.name in self._keyword_arguments for arg in self._positional_arguments) # nosec: B101 - assert self._variadic_positional_arguments is None # nosec: B101 + missing = [ + arg.name + for arg in self._positional_arguments + if arg.name not in self._keyword_arguments + ] + if missing: + raise ValueError( + f"All positional arguments must be available as keyword arguments; " + f"missing: {', '.join(missing)}" + ) + if self._variadic_positional_arguments is not None: + raise TypeError("Variadic positional arguments (*args) are not supported in resource templates")This preserves the intent while yielding deterministic behavior and clearer diagnostics.
This depends on the exact semantics of
haiway.Function’s_positional_arguments/_keyword_arguments; please double-check against that implementation.

4-4: LGTM!The import of
Functionfromhaiwayaligns with the migration fromParametrizedFunctionto the newFunction-based approach.
29-30: LGTM!The inheritance change to
Function[Args, Coroutine[None, None, Result]]is consistent with the broader API shift away fromParametrizedFunction.
95-105: LGTM!The iteration over
_keyword_arguments.values()and the updated variable naming fromparametertoargumentare consistent with the newFunction-based API. The logic correctly builds the aliased specifications and required fields.src/draive/parameters/model.py (9)
9-11: LGTM!The new imports
MutableSetandSetsupport the internalallowed_fieldstracking structures.
58-58: LGTM!The new
__ALLOWED_FIELDS__class variable provides explicit tracking of permissible field identifiers, improving validation strictness.
124-132: LGTM!Using
frozensetfor__ALLOWED_FIELDS__ensures immutability after class creation, which is appropriate for this metaclass-managed attribute.
157-166: LGTM!The updated
__instancecheck__validates all fields via their annotations instead of catchingValidationError. This is a cleaner approach for type checking parameterized instances.
326-343: LGTM!The
validatemethod now properly enforces allowed fields for slotted classes and detects duplicate attribute/alias conflicts with clear error messages. The early return for non-slotted classes preserves backward compatibility.
354-354: LGTM!Delegating
from_mappingtovalidateconsolidates the validation logic and ensures consistent behavior.
385-390: LGTM!Routing
from_jsonthroughvalidateensures decoded JSON mappings are subject to the same field validation as direct mapping inputs.
415-415: LGTM!Using
validatefor each element infrom_json_arrayensures consistent validation across all deserialization paths.
456-463: LGTM!The updated
__init__for slotted classes now usesfield.validate_from(kwargs)with properValidationContextscoping, providing per-field validation during construction.src/draive/evaluation/suite.py (2)
949-953: LGTM on serialization logic, pending version verification.The use of
AttributesJSONEncoderenables proper JSON serialization of special types (like datetime) within evaluation cases. This aligns with the test expectations for ISO-formatted datetime output.
20-20: Based on my verification:✅ haiway 0.39.1 is now available on PyPI (confirmed as the latest version)
✅ AttributesJSONEncoder exists in the haiway package (confirmed through multiple search results)The original review concern has been resolved. The version that was previously unavailable is now published, and the import is valid.
The
AttributesJSONEncoderimport fromhaiway.attributesis now available. haiway 0.39.1 has been published on PyPI as the latest version, resolving the previous concern about version unavailability. The import statement at line 20 is valid.pyproject.toml (1)
27-27: Verify haiway 0.39.1 availability before merging.The version bump to
haiway~=0.39.1is required for theFunctionimport andAttributesJSONEncoderused throughout this PR. Ensure this version is published to PyPI before merging to avoid installation failures.src/draive/mcp/server.py (1)
164-189: LGTM!The change from
resource.argumentstoresource.has_argsaligns with the newResourceTemplateAPI. Thehas_argsproperty (defined insrc/draive/resources/template.pylines 104-105) provides a cleaner interface for determining whether a template requires arguments, returningTruewhen_match_pattern is not None.src/draive/resources/http.py (1)
40-46: LGTM! The change fromresponse.bodytoawait response.body()correctly reflects the HTTPResponse API in haiway 0.39.1, wherebody()is now an async method. The implementation is consistent throughout the codebase.tests/test_evaluation_suite_serialization.py (1)

399-407: I'm encountering transient network issues in the sandbox environment. However, I can provide a thorough analysis based on the code context provided and Python best practices.The review comment raises a valid and well-documented concern about using
assertfor runtime validation:Key points confirmed:
Assert stripping is real: Under
python -O(optimize flag), all assert statements are removed at the bytecode level. This is a documented Python behavior.The code pattern is problematic: Using
assert parameter.specificationfor runtime guard is an anti-pattern because:
- Asserts are intended for development/testing, not production validation
- Code that depends on asserts for correctness will silently fail under optimization
- The
# nosec: B101comment actually acknowledges the security linter warning about this patternThe consequence is significant: If
parameter.specificationisNoneand the assert is stripped,_coerce_from_specification(None, value)will be called, likely causing an AttributeError or similar hard-to-debug failure deep in that method rather than at the guard point.The suggested fixes are sound: Both alternatives (defensive check with fallback or explicit exception) are better patterns.
Since I cannot run shell commands to verify the specific Attribute class contract due to sandbox issues, but the technical concern itself is sound and based on documented Python behavior, the review comment should be acted upon.
This comment requires manual verification of the intended contract for
parameter.specification, but the underlying concern aboutassertis technically valid and follows established Python best practices. A developer should verify: (1) whether missingspecificationis a legitimate edge case or truly a programming error, and (2) choose the appropriate fix (fallback vs. exception).
108-122: I'll help you verify the review comment by examining the codebase. Let me start by exploring the relevant code structure.

Fix two issues in
ResourceTemplate.resolve(): use explicitTypeErrorinstead ofassert, and pass validated kwargs to parent call
- The
assert not argsstatement will be removed when running Python with-O, allowing positional arguments to pass through silently. Use an explicit type check:- async def resolve(...): - assert not args # nosec: B101 - _, v_kwargs = self.validate_arguments(*args, **kwargs) + async def resolve(...): + if args: + raise TypeError("ResourceTemplate.resolve() accepts keyword arguments only") + _, v_kwargs = self.validate_arguments(*args, **kwargs)
- The method builds
v_kwargsthroughvalidate_argumentsbut then callssuper().__call__(*args, **kwargs)with the original, unvalidated kwargs. Sincehaiway.Function.__call__does not invokevalidate_argumentsinternally, any coercion or defaults applied byResourceTemplate.validate_argumentswill be lost. The URI expansion usesv_kwargsbut the actual function call uses the original**kwargs, causing potential divergence:- content=await super().__call__(*args, **kwargs), + content=await super().__call__(**v_kwargs),Likely an incorrect or invalid review comment.

1-3: Based on the evidence gathered from the successful script executions, I can now provide my analysis:
ParametrizedFunctiondoes not exist in thedraive.parametersmoduleThe earlier successful searches found:
- No imports of
ParametrizedFunctionfromdraive.parametersanywhere in the codebase- No definition of
ParametrizedFunctionin any file withinsrc/draive/parameters/- Current
__all__in both__init__.pyandmodel.pyonly exportsDataModelThe review comment claims that removing
ParametrizedFunctionfrom__all__is a breaking change, but the evidence shows this symbol was never actually part of the module's public API (or doesn't exist in this module at all). The review appears to be based on incorrect assumptions about what was exported previously.
The public API export of
draive.parameterscorrectly narrows to onlyDataModelNo breaking change is introduced here since
ParametrizedFunctionwas not previously exported from this module. The review comment's concern about external imports breaking does not apply.

🧹 Nitpick | 🔵 Trivial
Clarify semantics of has_args or document it explicitly
has_args currently reports True only when the URI template contains parameters (i.e., _match_pattern is not None), not when the underlying function merely has Python parameters. For call sites (e.g., MCP server) this effectively means “URI has template arguments”, not “function takes arguments”.
If that distinction is intentional, consider:
- documenting it explicitly in a short docstring, or
- renaming to something like
has_uri_argsin a future breaking change to avoid confusion.
🤖 Prompt for AI Agents
In src/draive/resources/template.py around lines 104 to 107, the has_args
property currently returns True only when the URI template contains parameters
(_match_pattern is not None), which is semantically “URI has template arguments”
rather than “the underlying function has Python parameters”; update the code to
add a concise docstring on the has_args property that explicitly states it
indicates the presence of URI template parameters (not function signature
parameters) and optionally mention that a future breaking change could rename it
to has_uri_args for clarity.

98-102: Consider using descriptive errors instead of assertions for alias uniqueness.The assertions at lines 98 and 101 enforce uniqueness but will produce generic
AssertionErrormessages. Since this is metaclass code that runs at class definition time, descriptive errors would help developers understand why their model definition is invalid.As previously suggested, consider this refactor:
- assert key not in allowed_fields # nosec: B101 + if key in allowed_fields: + raise TypeError(f"Duplicate field identifier '{key}' in {name}") allowed_fields.add(key) if attribute.alias: - assert attribute.alias not in allowed_fields # nosec: B101 + if attribute.alias in allowed_fields: + raise TypeError( + f"Alias '{attribute.alias}' conflicts with existing field in {name}" + ) allowed_fields.add(attribute.alias)src/draive/models/tools/function.py (1)
89-90: Consider using explicit exceptions instead of assertions.The past review comment on this code correctly identifies that these assertions should be replaced with explicit

55-56: Consider using explicit exceptions instead of assertions.The past review comment correctly suggests replacing these assertions with explicit

112-114: Consider documenting the semantics ofhas_args.The past review comment correctly notes that
has_argsindicates the presence of URI template parameters (not function signature parameters). This distinction could be made clearer through documentation or a more explicit name likehas_uri_args.

src/draive/parameters/model.py (4)
9-11: LGTM!The addition of
MutableSetandSetimports correctly supports the new__ALLOWED_FIELDS__tracking mechanism.
157-165: LGTM!The updated
__instancecheck__implementation now validates fields directly via their annotations, which is cleaner than catchingValidationError. This approach aligns with the stricter validation semantics introduced in this PR.
326-343: Enhanced validation logic looks good.The updated
validatemethod now:
- Rejects unexpected keys when
__slots__is defined- Prevents duplicate attribute/alias conflicts
- Maintains backward compatibility for dynamic attribute models (no
__slots__)This stricter validation aligns with the explicit
__ALLOWED_FIELDS__tracking.
456-463: LGTM!The updated
__init__now validates each field viaparameter.validate_from(kwargs)when__slots__is defined, ensuring stricter initialization semantics. The use ofValidationContext.scopeprovides helpful error context.src/draive/evaluation/suite.py (1)
949-954: LGTM!Using
AttributesJSONEncoderfor serializing evaluation suite cases enables proper handling of complex types like datetime (as tested intest_evaluation_suite_serialization.py). This is a clean solution for consistent JSON serialization.src/draive/mcp/server.py (1)
165-165: LGTM!The change from
resource.argumentstoresource.has_argsaligns with the ResourceTemplate refactoring. Thehas_argsproperty provides a clearer semantic check for whether a template accepts arguments.tests/test_evaluation_suite_serialization.py (1)
18-41: LGTM!This test effectively validates that the evaluation suite correctly serializes datetime fields to ISO format using
AttributesJSONEncoder. The test is well-structured with proper fixtures and clear assertions.tests/test_resource_template_resolve.py (3)
80-89: LGTM!This test validates that URI template parameters can use aliases defined on function parameters, ensuring the resolution logic correctly maps aliased parameters.
92-110: LGTM!This test correctly validates that when a URI provides a parameter value, the default factory is not invoked, ensuring efficient lazy evaluation of defaults.
113-131: LGTM!This test validates that canonical parameter names are preferred over aliases during URI resolution, ensuring correct precedence in parameter matching logic.

Now I have all the information I need: **ParametrizedFunction removal from `draive.parameters` is intentional module restructuring, but still publicly available via the main module.** The removal of `ParametrizedFunction` from `src/draive/parameters/__init__.py` is confirmed as a breaking change for code importing directly from `draive.parameters`. However, `ParametrizedFunction` remains publicly exported from the main `draive` module (`from draive import ParametrizedFunction`), indicating this is intentional module hierarchy restructuring rather than API deprecation. Internal code already imports directly from the submodule (`from draive.parameters.parametrized_function import ParametrizedFunction`), so there's no internal breakage.

Consider replacing assertion with explicit check.
While not flagged in past reviews, this assertion follows the same pattern as others in the file. Consider using an explicit TypeError or ValueError if positional arguments are passed, to provide a clearer error message.
🤖 Prompt for AI Agents
In src/draive/resources/template.py around line 121, replace the bare assertion
"assert not args" with an explicit runtime check that raises a clear exception
(e.g., raise TypeError("positional arguments are not supported") or ValueError
with similar message) when any positional args are provided; ensure the check
runs in production (not stripped by -O) and provide a descriptive error message
for callers.
