What is Resend?
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
What is Rootly?
Rootly keeps widening what its AI observes — now the incident call itself, in any language.
The AI work runs along two lines: evidence gathering across the observability stack, and the incident call itself. Meeting Scribe now detects the language spoken on a call and transcribes it with no configuration, removing the setup step that made the feature single-language in practice. Around it sits the routine platform work — catalog sync, alert-storm muting, on-call widgets, retrospective templates.

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
◆ Current state
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
◆ Where it's heading
Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.
◆ Prediction
Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
Rootly
6.3INFRA · APIS
Rootly keeps widening what its AI observes — now the incident call itself, in any language.
◆ Current state
The AI work runs along two lines: evidence gathering across the observability stack, and the incident call itself. Meeting Scribe now detects the language spoken on a call and transcribes it with no configuration, removing the setup step that made the feature single-language in practice. Around it sits the routine platform work — catalog sync, alert-storm muting, on-call widgets, retrospective templates.
◆ Where it's heading
The pattern is consistent: every artifact an incident produces — telemetry, chat, the call — becomes something Rootly's AI reads and turns into retrospective material. Language detection is a small change with a specific consequence: distributed teams whose incident calls are not held in English now get the same automated record as everyone else. The catalog and alerting work underneath keeps making that record attributable to a service and an owner.
◆ Prediction
Expect Scribe output to feed the retrospective AI-blocks directly, closing the loop from call to written retrospective without a manual step.
