 Why Bun?
+
 - This tool is written in TypeScript and uses Bun's native TypeScript execution (no compilation step)
 - The CLI uses a `#!/usr/bin/env bun` shebang for direct execution
-- Bun's speed makes the agent loop faster and more responsive

+
+**[OpenCode](https://opencode.ai) is required** to run this tool.

+Iteratively run the agent loop until all tasks are complete. Each iteration will:
+
+- Read the `TASKS.md` file to find the next task to complete
+- Invoke the agent with the `PROMPT.md` file and the `TASKS.md` file
+- The agent will complete the task and update the `TASKS.md` file
+- The agent will log its learnings to the `LEARNINGS.md` file
+- The agent will commit the changes to the repository
