+# ADK Issue Triaging Assistant
+
+The ADK Issue Triaging Assistant is a Python-based agent designed to help manage and triage GitHub issues for the `google/adk-python` repository. It uses a large language model to analyze new and unlabelled issues, recommend appropriate labels based on a predefined set of rules, and apply them.
+
+This agent can be operated in two distinct modes: an interactive mode for local use or as a fully automated GitHub Actions workflow.
+
+---
+
+## Interactive Mode
+
+This mode allows you to run the agent locally to review its recommendations in real-time before any changes are made to your repository's issues.
+
+### Features
+* **Web Interface**: The agent's interactive mode can be rendered in a web browser using the ADK's `adk web` command.
+* **User Approval**: In interactive mode, the agent is instructed to ask for your confirmation before applying a label to a GitHub issue.
+
+### Running in Interactive Mode
+To run the agent in interactive mode, first set the required environment variables. Then, execute the following command in your terminal:
+
+```bash
+adk web
+```
+This will start a local server and provide a URL to access the agent's web interface in your browser.
+
+---
+
+## GitHub Workflow Mode
+
+For automated, hands-off issue triaging, the agent can be integrated directly into your repository's CI/CD pipeline using a GitHub Actions workflow.
+
+### Workflow Triggers
+The GitHub workflow is configured to run on specific triggers:
+
+1.  **Issue Events**: The workflow executes automatically whenever a new issue is `opened` or an existing one is `reopened`.
+
+2.  **Scheduled Runs**: The workflow also runs on a recurring schedule (every 6 hours) to process any unlabelled issues that may have been missed.
+
+### Automated Labeling
+When running as part of the GitHub workflow, the agent operates non-interactively. It identifies the best label and applies it directly without requiring user approval. This behavior is configured by setting the `INTERACTIVE` environment variable to `0` in the workflow file.
+
+### Workflow Configuration
+The workflow is defined in a YAML file (`.github/workflows/triage.yml`). This file contains the steps to check out the code, set up the Python environment, install dependencies, and run the triaging script with the necessary environment variables and secrets.
+
+---
+
+## Setup and Configuration
+
+Whether running in interactive or workflow mode, the agent requires the following setup.
+
+### Dependencies
+The agent requires the following Python libraries.
+
+```bash
+pip install --upgrade pip
+pip install google-adk requests
+```
+
+### Environment Variables
+The following environment variables are required for the agent to connect to the necessary services.
+
+* `GITHUB_TOKEN`: **(Required)** A GitHub Personal Access Token with `issues:write` permissions. Needed for both interactive and workflow modes.
+* `GOOGLE_API_KEY`: **(Required)** Your API key for the Gemini API. Needed for both interactive and workflow modes.
+* `OWNER`: The GitHub organization or username that owns the repository (e.g., `google`). Needed for both modes.
+* `REPO`: The name of the GitHub repository (e.g., `adk-python`). Needed for both modes.
+* `INTERACTIVE`: Controls the agent's interaction mode. For the automated workflow, this is set to `0`. For interactive mode, it should be set to `1` or left unset.
+
+For local execution in interactive mode, you can place these variables in a `.env` file in the project's root directory. For the GitHub workflow, they should be configured as repository secrets.
