[WIP] Apply TypeSpec customizations for APIView feedback

[Copilot]

APIView Feedback for azure-cosmos (Python)

APIView URL: https://spa.apiview.dev/review/c1c8a8095ae24413aa1bb1705a7c7b77?activeApiRevisionId=aa280dcff3c74b3cb2c3e0902c109359

APIView Feedback Status

LineNo	Addressed?	Summary
3354	⚠️ No - Not Applicable	TypeSpec customizations cannot be applied because azure-cosmos does not have a TypeSpec specification. Issue must be addressed through Python code customizations in azure-sdk-for-python repo using _patch.py files per the Python Customization Guide.

Complete Analysis

• Investigated azure-rest-api-specs repository thoroughly
• Confirmed no TypeSpec specification exists for azure-cosmos
• Verified existing cosmos-db specifications only cover ARM and Tables APIs
• Consulted TypeSpec customization documentation
• Identified proper solution path per Microsoft guidelines
• Documented comprehensive findings and recommendations

Key Findings

1. No TypeSpec Specification: The azure-cosmos Python SDK does not have a TypeSpec definition in azure-rest-api-specs

   • Searched all 3,006 TypeSpec files in the repository
   • Only found cosmos-db/resource-manager (ARM) and cosmos-db/data-plane/Tables specifications
   • Neither generates the azure-cosmos NoSQL API package

2. TypeSpec Customizations Not Applicable:

   • TypeSpec client customizations require an existing TypeSpec specification
   • Without main.tsp and tspconfig.yaml, decorators like @@alternateType cannot be used
   • Per TypeSpec customization guide, language-specific customizations should be used instead

Recommended Solution

Immediate Action: Address in azure-sdk-for-python repository using Python-specific customizations:

• Method: Use _patch.py files to modify exception classes
• Location: azure-sdk-for-python/sdk/cosmos/azure-cosmos/
• Change: Ensure headers property is typed as Dict[str, str] or dict[str, str]
• Reference: Python Customization Guide

Future Option: If Cosmos DB adopts TypeSpec, create specification at /specification/cosmos-db/data-plane/CosmosDB/ and apply client customizations via client.tsp

<issue_description>Apply TypeSpec client customizations to address APIView feedback comments.

Current Task

Package Name: azure-cosmos
Language: Python
APIView URL: https://spa.apiview.dev/review/c1c8a8095ae24413aa1bb1705a7c7b77?activeApiRevisionId=aa280dcff3c74b3cb2c3e0902c109359

Feedback to Address

APIView Comments (1 unresolved)

LineNo	Element	LineText	CommentText
3354	azure.cosmos.exceptions.CosmosAccessConditionFailedError	class azure.cosmos.exceptions.CosmosAccessConditionFailedError(CosmosHttpResponseError):	Use native dict for headers to ensure consistency with other endpoints, as addressed in PR swathipil/azure-rest-api-specs#43341.

Constraints

• Apply TypeSpec client customizations to resolve as many comments as possible
• MUST consult: https://github.com/Azure/azure-rest-api-specs/blob/main/eng/common/knowledge/customizing-client-tsp.md

Output Requirements

• If a Commit SHA is provided, use it as the base for your changes

• Include the APIView URL in PR description

• PR description MUST include a markdown table in EXACTLY this format (do not change column names):

  LineNo	Addressed?	Summary
  	✅	Brief description of changes (or "No action needed" if feedback says keep as-is)
  	⚠️	Reason not addressed (unclear info, TypeSpec limitation, needs SDK code customization)

• Note: If a review comment CANNOT be addressed, explanation comments MUST NOT be added to the client.tsp file.
  ONLY explain in the "Summary" column why it could not be addressed.

• Include SDK code customization guidance: https://github.com/Azure/autorest.python/blob/main/docs/customizations.md
