+# git-agent
+
+**git-agent** is a natural-language Git assistant built with [LangChain](https://github.com/langchain-ai/langchain) and OpenAI function calling. Instead of remembering Git commands, you just describe what you want to do — and the agent does it.
+
+## What it does
+
+Run `git-agent` from inside any local repository and pass a plain-English instruction as an argument. The agent reads the current repository state via `git status`, reasons about your intent, and executes the appropriate Git operation using one of its four tools:
+
+| Tool | What it does |
+|---|---|
+| `git_status` | Inspects the working tree — automatically called for context before every instruction |
+| `git_diff` | Shows colourised diffs between the working directory and the last commit, scoped to specific files if requested |
+| `git_add` | Stages files for the next commit |
+| `git_restore` | Restores specified files to their last-committed state (discards local changes) |
+
+## Example usage
+
+```shell
+# Install
+pip install git+https://github.com/jupyterjazz/git-agent.git
+
+# Set your OpenAI key
+export OPENAI_API_KEY=<your-key>
+
+# Ask it something (run from inside a repo)
+git-agent "show me what changed in the authentication module"
+git-agent "stage only the files related to the login feature"
+git-agent "restore the config file to its last committed version"
+```
+
+The agent maps your intent to the right Git command and executes it — colourising diff output (cyan for headers, red for deletions, green for additions) so it's easy to read at a glance.
+
+## Model
+
+Uses `gpt-3.5-turbo-0613` via OpenAI function calling (structured tool dispatch — no free-form shell execution).
+
+## Compliance note
+
+`git_restore` is a destructive, irreversible operation. The agent only restores files you explicitly ask about; it will not restore additional files unless you ask for all of them.
