 # Coding Agent for Slack (Bolt for Python and Pydantic AI)
 
-A sample Slack **coding agent** built with [Bolt for Python](https://docs.slack.dev/tools/bolt-python/) and [Pydantic AI](https://ai.pydantic.dev/) using models from [Anthropic](https://anthropic.com) or [OpenAI](https://openai.com). When you mention the agent, it decides whether to reply in place or create a dedicated **code channel** for the work. In a code channel it clones a repository into a temp workspace, does real work there, and keeps the channel's plan, context bar, and code tab current as it goes.

 > [!WARNING]
 > **This agent runs commands generated by a language model on the machine running the app.** Only read-only commands and local git changes run without asking. Everything else, including the repo's own tests and builds, needs approval in Slack before it runs (see [Command approvals](#command-approvals)), and anyone in the code channel can approve. Approval is the safety gate, so read each command before you approve it. Commands run without the app's tokens or anything that looks like a credential in their environment. **Only run this sample against trusted, throwaway repositories, and on a machine you're comfortable letting it operate.** It is a reference sample, not a hardened product.
