Walkthrough

A new asynchronous function, generate_hint_v3, was introduced to generate structured hints for accepted solutions, utilizing a detailed prompt format and AST diffs for Java files. The hint generation workflow was updated to use this new function instead of the previous version when a file is accepted. No other logic or error handling was changed.

Changes

File(s) Change Summary
.../server.py Added generate_hint_v3 for structured hint generation using AST diffs and updated call from generate_hint_v2 to generate_hint_v3 in the file acceptance workflow.

Poem

A hinting hare with clever mind,
Now crafts its prompts in structured kind.
With AST diffs and Java lore,
Solutions’ secrets it will explore.
Version three now takes the stage—
Hopping forward, hint by page!

557-573: Improve prompt structure and validation.

The structured prompt format is a good improvement, but consider adding validation to ensure the LLM response follows the expected format.

Add response validation:

+def validate_hint_response(response_content: str) -> bool:
+    """Validate that the response follows the expected format."""
+    content = str(response_content).strip()
+    return (
+        "SUMMARY:" in content 
+        and "HINT:" in content 
+        and content.count("---") >= 2
+    )

 async def generate_hint_v3(
     kai_ctx: KaiSolutionServerContext,
     client_id: str,
 ) -> None:
     # ... existing code ...
     
     response = await kai_ctx.model.ainvoke(prompt)
+    
+    if not validate_hint_response(response.content):
+        print(
+            f"Warning: Generated hint for client {client_id} does not follow expected format",
+            file=sys.stderr,
+        )

536-554: Consider removing or deprecating older hint generation versions.

With the introduction of v3, consider whether v1 and v2 are still needed. If not, they should be deprecated or removed to reduce code maintenance burden.

Add deprecation warnings or remove unused versions:

+import warnings
+
 async def generate_hint_v1(
     kai_ctx: KaiSolutionServerContext,
     client_id: str,
 ) -> None:
+    warnings.warn(
+        "generate_hint_v1 is deprecated. Use generate_hint_v3 instead.",
+        DeprecationWarning,
+        stacklevel=2
+    )
     # ... existing code ...

 async def generate_hint_v2(
     kai_ctx: KaiSolutionServerContext,
     client_id: str,
 ) -> None:
+    warnings.warn(
+        "generate_hint_v2 is deprecated. Use generate_hint_v3 instead.",
+        DeprecationWarning,
+        stacklevel=2
+    )
     # ... existing code ...

868-868: LGTM! Function call correctly updated to use v3.

The function call update is appropriate and consistent with the introduction of the new hint generation version.
