The PoC for CodeRhapsody took 14 days, and provided significant gains in productivity by:
- Providing hints to the AI in real time as it works
- Enabling better use of feedback from the AI to help guide it
- Eliminating distractions from the rest of the IDE
The next generation of AI coding agents will enable experienced SWEs to 4X their productivity, but this isn’t mode for kiddy vibe coders. You must be the expert, or you’ll destroy your code base in minutes, forcing a git reset.
The old way to code with the AI was to craft a prompt, launch, and start over if anything goes wrong. The new way is to craft a prompt, launch, and provide hints as the AI works, such as “Please use the existing fake, not a mock”, or “ThinkingBlocks should implement the ContentBlock interface”. When you see it making poor decisions, you correct them in real time.
The biggest change in tooling is that user prompts sent while the AI is working should be hints included in the next tool result message, not a replacement that stops the current chain of work. The most important feature for this is actionable visible thinking, which tells you what the AI is doing and why.
The leading AI models differ on thinking feedback:
- Claude Sonnet 4.5 leads, with clear, concise, and actionable thinking feedback
- Gemini 2.5 Pro provides verbose, but actionable feedback
- ChatGPT5-Codex is completely silent
The future of AI coding for experts will support real-time guidance.
