Copilot CLI dynamic workflows: let them call the Sume CLI

The GitHub changelog for October 1, 2026 lists "Dynamic workflows in Copilot CLI and the Copilot app" as a new feature. To let those workflows drive Sume, install the Sume CLI skill pack and point an MCP client at https://mcp.sume.com/mcp.

Install the skill pack

The Sume CLI bundles an agent skill. sume skills install writes it into .agents/skills or .claude/skills; use export to review the files first.

sume login
sume skills list
sume skills export sume   # read before installing
sume skills install

Keep paid work gated

The CLI docs tell agents to use read commands while planning and to require confirmation for writes. --confirm-submit covers non-paid writes; --confirm-paid covers Avatar and Avatar Video generation that can spend credits. Image, Video and Music generation are not CLI submit commands, so call the Developer API for those and use the CLI for job recovery.

• sume doctor --agent --json
• sume catalog list --json
• sume jobs status <job_id> --agent --json
• sume jobs result <job_id> --agent --json

Add the MCP endpoint

Hosted MCP works with HTTP MCP clients: point the client at the URL and complete its OAuth login. Default OAuth is read-only (mcp:read); paid and write tools need mcp:write and an idempotency_key. I did not read Copilot's own MCP configuration steps, so follow GitHub's docs for where to add the server.

A safe loop

Let the workflow inspect the catalog, validate the payload, ask a person to confirm spend, submit one bounded job, then recover through status, events and result. Summaries should not paste secrets or signed URLs.
