Prompt functions return raw dicts, incompatible with fastmcp >= 3.x

[jslitzkerttcu]

Bug

All five prompt functions in prompts.py return list[dict] (e.g., [{"role": "user", "content": "..."}]), but fastmcp >= 3.x requires each item in the list to be a Message object or str.

Version: code-review-graph 2.3.3, fastmcp 3.3.1

Error

Calling any MCP prompt (e.g., architecture_map) throws:

McpError: MCP error 0: Error rendering prompt 'architecture_map':
messages[0] must be Message or str, got dict.
Use Message({'role': 'user', 'content': '...'}) to wrap the value.

The error originates from fastmcp/prompts/base.py line ~310, where the _resolve method iterates the returned list and only accepts Message or str instances.

Root Cause

prompts.py returns plain dicts:

def architecture_map_prompt() -> list[dict]:
    return [
        {
            "role": "user",
            "content": "...",
        }
    ]

This worked with older fastmcp versions that accepted raw dicts, but fastmcp 3.x tightened the contract.

Fix

Import Message from fastmcp and wrap each dict:

from fastmcp.prompts import Message

def architecture_map_prompt() -> list[Message]:
    return [
        Message("...", role="user")
    ]

Same change needed for all five functions: review_changes_prompt, architecture_map_prompt, debug_issue_prompt, onboard_developer_prompt, pre_merge_check_prompt — plus the corresponding wrapper functions in main.py.
