We often blame the model when the output is bad, but usually, the prompt is the culprit. We miss a constraint, forget the context, or use the wrong mode for the job. A savvy developer known as u/TrueEstablishment630 just released a solution called Buddy to fix this exact loop.
The Concept
Buddy is an open-source “prompt coach” that runs alongside your workflow. Instead of just rewriting your text automatically, the creator designed it to analyze your inputs in real time. It watches your prompt structure and your tool settings, then offers specific feedback on how to make them better.
The Twist
Most tools in this space are “optimizers” that silently fix your bad prompting. The twist here is that this tool refuses to do the work for you. The author built it to teach you, not replace you. It points out why a prompt might fail, such as missing examples or over-reliance on the model’s internal knowledge, so you actually improve your skills over time.
How it helps you
Here is how the expert designed the feedback loop to work:
- Structural Audit: 📝 It scans for missing core elements like context, constraints, and output formatting.
- Mode Switching: 🛠️ It suggests the right tool for the job, such as recommending code execution for math or search for recent events.
- Risk Management: 🛡️ The tool flags potential privacy issues or known areas where the model is likely to hallucinate.
- Unstuck Mode: 💡 If you hit a wall, it suggests a better next prompt to keep the conversation moving.
Pro Tip
Because the creator made this open source, you aren’t stuck with their default rules. You can run this locally and customize the coaching behavior. This is perfect for team leads who want to enforce specific prompting standards across a group without manually reviewing every chat log!
