Seamless Agent
Seamless Agent enhances GitHub Copilot by providing interactive user confirmation tools. It allows AI agents to ask for user approval before executing actions, ensuring you stay in control.
Features
A Language Model tool that enables Copilot to interactively prompt you for confirmation or additional input during chat sessions.
- User Confirmation — Get explicit approval before Copilot executes critical actions
- Interactive Input — Provide additional context or instructions mid-conversation
- Task Validation — Confirm whether a task was fulfilled your specs
- Seamless Integration — Works naturally within the Copilot Chat workflow
A Language Model tool that presents a multi-step plan in a dedicated review panel, so you can approve it or request changes with comments anchored to specific parts of the plan.
- Plan Review Panel — Review the plan in a focused editor-like view
- Targeted Feedback — Add comments tied to specific headings/paragraphs/list items
- Structured Output — Returns
{ approved, comments: [{ citation, comment }] } to the agent
- Safer Automation — Prevents execution before you approve the approach
Usage
Once installed, the ask_user and approve_plan tools are automatically available to GitHub Copilot Chat.
Automatic Usage
Copilot will automatically use this tool when it needs your confirmation. When triggered:
- A notification appears in VS Code
- Click "Open Console" to open the request panel
- Type your response
- Copilot continues based on your input
Reviewing a Plan with approve_plan
Copilot will use this tool when it wants your sign-off on a plan before proceeding. When triggered:
- A “Review Plan” editor panel opens
- Hover a heading/paragraph/list item and click the comment icon to add feedback
- Click Approve to proceed, or Request Changes to send feedback back to the agent
- Copilot continues based on
{ approved, comments }
Tips
Recommended System Prompt
To ensure the AI requests approval at the right times, add the following to your custom instructions or system prompt:
When the task requires multiple steps or non-trivial changes, present a detailed plan using #approvePlan and wait for approval before executing.
If the plan is rejected, incorporate the comments and submit an updated plan with #approvePlan.
Always use #askUser before completing any task to confirm the result matches what the user asked for.
You can add this into your .github/copilot-instructions.md file in your project
Quick tutorial: using approve_plan
If you want to explicitly trigger plan review from the start, ask Copilot something like:
Before you change anything, write a step-by-step plan and present it with #approvePlan.
Wait for my approval (or requested changes). Only then implement the plan.
