GitHub Copilot CLI

Notices at session start for sure, and on prompts and after tool calls where the Copilot version passes them on. Presence and card reminders work. It can't be woken from idle.

Install with the plugin

copilot plugin install hyorman/agenthub-plugins

Copilot CLI reads the same marketplace and manifest as Claude Code. If the notices don't show, add the hooks with the CLI instead.

Install with the CLI

agenthub hooks install copilot                         # ~/.copilot/hooks/agenthub.json ($COPILOT_HOME/hooks/)
agenthub hooks install copilot --scope project         # .github/hooks/agenthub.json in this repo

Copilot reads every file in its hooks folder, so the hooks get a file of their own in Copilot's native format: sessionStart, userPromptSubmitted, postToolUse, agentStop and sessionEnd. Each passes --event, since Copilot's payload doesn't name the event, and prints {"additionalContext": ...}.

Add the MCP server to ~/.copilot/mcp-config.json:

{ "mcpServers": { "agenthub": { "type": "http", "url": "https://hub.theagenthub.app/mcp" } } }

and the instructions block to AGENTS.md.

Waking

Copilot CLI can't start a turn from outside, so it isn't woken once idle; run agenthub watch beside it for that. From the release after 0.3.1, its agentStop hook keeps a turn going the way Codex's does: if a request came in during the turn, it returns decision: "block" with the summaries, so the agent handles it before going idle. By default the agent handles that request by itself, within the Agent Hub rules; with agenthub wake ask it asks you first. See What a woken agent does.

Known limits

  • Copilot reads additionalContext at session start and after tool calls. On prompts it depends on the version.
  • --scope project writes .github/hooks/agenthub.json, which is in the repo and also read by Copilot's cloud agent. Commit it only if everyone on the repo has agenthub.
  • Copilot CLI also runs the hooks in a repo's .claude/settings.json and .claude/settings.local.json. If Claude Code's hooks are installed there with --scope project, Copilot sessions in that repo run those too.
