Execution harness · your own GitHub Copilot login
Run your chats on GitHub Copilot
Pick GitHub Copilot as the harness in any thread and the round runs on the Copilot CLI under your GitHub account — the mesh tools, nodes and context you already have, driven by a different engine.
What installing does
Installing places the harness in your chat picker only — it lands at {you}/Harness/Copilot.
It never appears for users who haven't opted in, because it needs a personal GitHub Copilot
login: there is no shared key and nothing is billed to the mesh.
- Get the plugin — the harness appears in your thread's harness picker.
- Pick it in a thread, then run
/loginto connect your GitHub account. - Chat as usual — same threads, same tools, same mesh content.
Uninstalling removes it from your picker again; threads that had selected it fall back to the standard MeshWeaver agent path, so nothing breaks and no history is lost.
Good to know
- The Copilot runtime ships with the platform (feature flag
Features:Ai:Clis:Copilot) — this package is purely the per-user opt-in, which is why it is small. - It is a harness, not an agent: it changes what executes the round, not which agent you talk to.
- Nothing is shared. Your account, your login, your picker.
