Microsoft CopilotShipped October 12, 2026
Lucid
What broke. In Copilot Studio the org-chart tool never ran. Its rows had no declared type, so Copilot stopped before the call and showed “Error code: SystemError”. Typing the rows exposed a second problem: Copilot sent every row with only the first row’s fields. The person at the top has no manager, so every row arrived without one and no chart was made.
The fix. Lucid typed the row fields and asked for managerId on every row, with an empty value for the person at the top. That is the change we had tested through a proxy.

Agent sign-upShipped September 10, 2026
Headless Domains
What broke. Every agent got a working API key, but there was no endpoint to check it. One agent in 11 looked for a “who am I” endpoint and got a 404. Three “checked” the key on a public endpoint that works without one, which proves nothing. The revoke address they published returned a 404 page.
The fix. Headless Domains shipped GET /api/v1/agents/me and POST /oauth2/revoke, and added one sentence to their auth.md telling agents to check a new key with /api/v1/agents/me.

Before the fix, 3 agents “checked” the key on the endpoint that needs no key. After it, none did.
