+# Foundry Agent Canvas
+
+A GitHub Copilot App canvas extension for designing Microsoft Foundry hosted
+agents from a side panel. It combines live Foundry project discovery with
+project-aware prompts to Copilot, portal handoffs, and an embedded local Agent
+Inspector.
+
+## Features
+
+- **Project picker** - sign in, search subscriptions and Foundry projects, switch projects, and retain the
+  selection across canvas reopens.
+- **Live project resources** - browse deployed models, Foundry Toolboxes and
+  their tools, project skills, and account guardrails.
+- **Project-aware chat handoff** - model, toolbox, skill, guardrail,
+  initialization, and deployment choices send a ready-to-run prompt to the
+  current Copilot session with the selected project, subscription, and endpoint
+  attached.
+- **Embedded Agent Inspector** - **Inspect Locally** launches or reuses
+  `azd ai agent run --no-inspector` in the Copilot integrated terminal, waits
+  for the agent on port `8088`, and embeds the bundled inspector. Inspector
+  errors can be sent back to Copilot as fix requests.
+
+## Install
+
+Add the Awesome Copilot marketplace, then install the extension:
+
+```bash
+copilot plugin marketplace add github/awesome-copilot
+copilot plugin install foundry-agent-canvas@awesome-copilot
+```
+
+To install it manually, copy this folder to
+`~/.copilot/extensions/foundry-agent-canvas/` for user scope or
+`.github/extensions/foundry-agent-canvas/` for project scope.
+
+## Usage
+
+
+1. Ask Copilot to *create a Foundry hosted agent*, then the canvas opens in the right panel automatically.
+2. Open the canvas project menu, sign in if needed, and choose a subscription and Foundry project.
+3. Create a hosted agent with a generated idea via **Inspire me**, or start from a **Hello world** sample prompt.
+4. Switch to other deployed models, connect existing toolboxes, skills, or guardrails for the created agent.
+5. Click **Deploy to Foundry** when the agent is ready.
+6. Click **Inspect Locally** after the workspace contains a runnable Foundry hosted agent.
