JSON-formatted output

[mark-undoio]

Describe the feature or problem you'd like to solve

A structured output mode to easily consume the output in other tools.

Proposed solution

My proposed solution is something similar to:

• Claude Code's --output-format stream-json
• Codex CLI's --json

The above tools provide their output in JSONL format with each interaction (tool use, assistant messages, etc) being supplied in an easily-parsed JSON format.

This makes integration with external tools simpler, allowing the agentic functionality of copilot to be easily used from scripts, third-party tools, etc.

Example prompts or workflows

• Integration with ad-hoc scripting (combined with the existing -p flag to supply a task) - output can be parsed using jq or similar to receive results or error codes.
• Integration with 3rd-party tools - output can be parsed and presented in the native interface of that tool, making it easier to integrate well with the Copilot AI ecosystem.
• Automated testing - make it easier to parse and reason about the output when evaluating prompts or testing MCP integrationsl.
