[AutoBuild] Introducing CaptainAgent

[LeoLjl]

This is the continued version of the previously introduced CaptainAgent.

CaptainAgent is an agent that can break down tasks and dynamically call AutoBuild as a tool to solve the subtasks. In one tool call, the CaptainAgent will provide the building task, execution task and group name. The building task is used to assemble group of experts, the execution task is what the experts need to solve.

We propose a RAG-like pipeline for expert group generation. Given a building task, we perform similarity search in agent library and find topk candidates, then let LLM to select the best fit. If no expert is suitable for the task, new experts will be generated. Tools will be retrieved and binded to the experts.

Below is the roadmap for merging it.

• Add full content of tool library.
• Add test for captain agent.
• Add agent library. The full content of agent library is too large and requires deduplication.
• Revise the notebook that introduces MetaAgent. The current one only involves tool library.
• Finish blog post.

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
