Python prompt context parameter

[evantahler]

Add context parameter support to Python prompt handlers for SDK parity and future-proofing, while ensuring backward compatibility.

This change uses inspect.signature to detect if a prompt handler accepts the context parameter, allowing both new and legacy handler signatures to coexist without breaking existing code.

Note

Introduce context parameter support for Python prompt handlers, automatically detected and propagated through Context and Server while preserving legacy handlers.

• Prompts/PromptManager:
  • Add PromptHandlerType supporting both legacy handler(args) and new handler(context, args) signatures with introspection-based detection.
  • Extend PromptHandler.get_messages and PromptManager.get_prompt to accept/pass context; raise PromptError if required context is missing.
  • Improve type handling (use get_type_hints, Annotated/Union unwrap, safe string refs) and cast results.
• Context:
  • Update Prompts.get to forward the active Context to the prompt manager.
• Server:
  • _handle_get_prompt now retrieves the current model context and passes it to the prompt manager.
• Tests:
  • Add comprehensive tests covering context-aware and legacy handlers, async/sync functions, mixed registration, logging with context, and error when context is required but absent.
• Version:
  • Bump package version to 1.14.1.

@cursoragent roll back the latest commit

[cursor]

I can do that, but quick check: do you want a safe revert (adds a new commit that undoes the latest one), or a history rewrite (reset/force-push)?

• Recommended for PRs: git revert HEAD (keeps history intact)
• Only if you’re OK rewriting history: git reset --hard HEAD~1 + force-push

Tell me which one you prefer and I’ll proceed.

@cursoragent roll back the latest commit

[cursor]

I can roll back the latest commit.

• If you want a history rewrite, I’ll drop it with git reset --hard HEAD~1 and then force-push the branch so the PR updates.
• If you’d rather keep history intact, I can revert it instead (git revert HEAD).

Which approach do you want?
