What is b3doc?

A small B-Cubed utility for turning R Markdown into publishable docs

b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.

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.

A small B-Cubed utility for turning R Markdown into publishable docs

◆ Current state

b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.

◆ Where it's heading

The direction is toward predictability over flexibility. The replace argument arrived in 0.2.0 generalising the earlier logo-specific behaviour, then 0.3.0 pulled regex support back out of it because escape characters and over-broad matches caused unintended edits. That is a maintainer choosing a narrower tool that fails obviously over a general one that fails quietly — a reasonable trade for a package that rewrites files in place.

◆ Prediction

Expect continued small releases driven by the documentation pipeline's needs, with output-quality defaults and front-matter handling the likely subjects rather than new functions.

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.
