Setup infrastructure:

  • Update Pyright configuration in pyproject.toml with comprehensive rules
  • Create analysis script to parse and categorize Pyright errors
  • Create progress tracker document
  • Create complex fixes documentation for deferred items

Initial fixes in aiwb.apiserver:

  • Add type arguments to AsyncGenerator in server.py
  • Fix return type in cli.py prepare_invocation_args (Mapping -> dict)
  • Convert parent Mapping to dict to allow modification

Complex errors deferred (11 errors):

  • Method override incompatibilities requiring class hierarchy review
  • Complex kwargs unpacking that Pyright cannot properly type-check

Stats: 2515 total errors across 12 packages

  • Fixed 2 simple type annotation errors in apiserver
  • Documented 11 complex errors for later review

@emcd emcd force-pushed the claude/pyright-type-cleanup-011CUyT2tnwT1i8xu3q6bBE6 branch from d1d8f69 to ceab32f Compare November 10, 2025 03:24
Simple fix:
- Add str type annotation to loads() function parameter in json.py
  (fixes 11 reportUnknown* errors)

Complex error deferred (1 error):
- reportMatchNotExhaustive: Match statement only handles specific chars
  Would require adding `case _: pass` which is a code change beyond type annotation

Progress: Fixed 11 errors with single type annotation. Only 1 error deferred.
…le fixes

Simple fixes in vectorstores (3):
- Add Factory return type to chroma.py and faiss.py prepare functions
- Add Dictionary type arguments to prepare() and prepare_clients() in core.py

Simple fixes in application (1):
- Add None return type to ExecuteServerCommand.__call__ abstract method

Complex errors deferred:
- vectorstores: 11 errors (Unknown container types, non-exhaustive match, abstract method return type)
- application: 42 errors (signal handler types, abstract class issues, kwargs unpacking, container types)

Note: Error counts increased as more type information revealed cascading type issues.
These require more extensive refactoring beyond simple type annotations.
Fixes in aiwb.__ (3 fixes):
- Add type arguments to Iterable and AsyncIterable in chain_async()
- Add type argument to PathLike in read_files_async()
- Add type argument to Sequence return type in read_files_async()

Fixes in aiwb.prompts (2 fixes):
- Add str type annotation to PromptTemplateAbsence.__init__ parameter
- Add dict type arguments to Instance.serialize() return type

Progress note: Using __.typx.Any for heterogeneous generic type parameters
allows fixing many missing type argument errors without additional imports.

Error counts:
- aiwb.__: 36 → 35 errors
- aiwb.prompts: 51 → 93 errors (type fixes revealed cascading issues)
…sive type cleanup

Type parameter additions (using __.typx.Any for heterogeneous containers):
- aiwb.__/nomina.py: Add type args to Pattern[str] and PathLike[str]
- aiwb.__/notifications.py: Add SimpleQueue[_NotificationBase] type parameter
- aiwb/application/state.py: Add type args to MappingProxyType, Dictionary, dict throughout
- aiwb/vectorstores/core.py: Add type annotations to clients and factories containers

Match statement suppressions:
- aiwb/codecs/json.py: Add # pyright: ignore[reportMatchNotExhaustive] to char matching
- aiwb/vectorstores/core.py: Add suppressions to both GenericResult match statements

Impact: Reduced errors from ~42 to 39 in these modules. Type information now flows
through the codebase enabling better downstream type checking.
Protocol suppressions in prompts/core.py for late-binding pattern.
Container typing and abstract class suppressions in application/cli.py.
Signal handler parameter typing with Signals enum.
Systematic suppression of late-binding Protocol instantiation pattern:
- invocables/ensembles: io, probability, summarization (Ensemble)
- locations/caches/simple: GeneralCache (2 locations)
- providers/clients/anthropic: conversers (5 processors), preparation (Provider)
- providers/clients/openai: preparation (Provider)

All follow same pattern: base class defines Protocol, subclasses provide concrete
implementations. Suppressions preserve late-binding behavior.

Updated progress tracker with comprehensive status.
Captured detailed Pyright output for gui package (1895 errors) for future
systematic cleanup work.
