I checked the current codebase and Copilot CLI support is not implemented right now.

The supported agent integrations currently verified in the repo are Claude, Codex, Cursor, Gemini, and OpenCode. I also could not find any copilot or Copilot integration references in the repository.

Relevant code:

• shared/src/modes.ts:41 - AgentFlavor is limited to claude | codex | gemini | opencode | cursor
• cli/src/commands/registry.ts:16 - registered CLI subcommands include codex, cursor, gemini, and opencode; the default command path is Claude
• web/src/components/NewSession/types.ts:1 - the web new-session UI only exposes claude | codex | cursor | gemini | opencode
• cli/README.md:3 - CLI docs list the currently supported session types
• docs/guide/installation.md:7 - installation docs list the supported external CLIs

Need more info:

• Do you mean GitHub Copilot CLI specifically, and if so which executable/interface should HAPI wrap?
• Should the first version support local sessions only, or full remote handoff/permission flow like the existing agents?
