Currently, in keen-code, we don't have a system prompt. Since it's a coding agent, we need one or more system prompts that are optimized for coding tasks. Explore the codebase in ../opencode and ../kimi-cli. Then based on the learnings, give me some ideas on how to approach system prompt for keen-code.
We will implement idea 2 and 3 where we have a static system prompt with dynamic environment variables along with rich context through AGENTS.md. Create a plan on this and save as output-3_system-prompt.md in the .ai-interactions/outputs/phase-4 directory.
There is a plan for system prompts in @.ai-interactions/outputs/phase-4/output-3_system-prompt.md. We need to implement this plan. First create todo list for yourself and then implement one by one.
