What is Dovetail?

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

What is lobstr?

R's object inspector is losing its view of the internals as CRAN closes off the private C API.

lobstr exposes R's internal object representation — sizes, addresses, reference counts, abstract syntax trees. Its two most recent releases are both driven by R's move to a restricted public C API: 1.1.3 stopped reporting a vector's truelength and reworked the reference indicator into refs:n, and 1.2.0 changed what sxp(expand = "environment") shows in order to stay compliant. 1.2.0 also adds src() for exploring srcref objects.

Dovetail
ANALYTICS
5.0

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

◆ Current state

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

◆ Where it's heading

The pattern across the last five releases is access, not capability. Digital Twins went from a two-step workaround — make a generic agent, then change its type — to a first-class create option, then gained a share link that lands a recipient in a conversation rather than a configure page. Chat is being simplified along the same line, with a thinner footer and scoped context that survives the jump to fullscreen. Dovetail is preparing these agents for people who will never build one.

◆ Prediction

Expect the sharing path to keep widening — permissions, guest access, or an embed for a twin link — since a link that opens straight into chat only pays off if it can safely leave the workspace.

R's object inspector is losing its view of the internals as CRAN closes off the private C API.

◆ Current state

lobstr exposes R's internal object representation — sizes, addresses, reference counts, abstract syntax trees. Its two most recent releases are both driven by R's move to a restricted public C API: 1.1.3 stopped reporting a vector's truelength and reworked the reference indicator into refs:n, and 1.2.0 changed what sxp(expand = "environment") shows in order to stay compliant. 1.2.0 also adds src() for exploring srcref objects.

◆ Where it's heading

The package is being rebuilt inside a shrinking window of what R permits. Each release trades some introspection depth for API conformance while trying to keep the diagnostic value intact — showing promise expressions instead of internal frame structures, replacing named with a documented refs scale. Where the constraint does not bite, development continues normally: src() is genuinely new, and the environment-binding fixes remove long-standing errors on for-loop and immediate bindings.

◆ Prediction

Expect further conformance work, since the notes describe it as ongoing, with any remaining non-API-dependent readouts either reworked or dropped as R tightens further.
