Claude Code v2.1.234

Groundwork for a Slack tagging integration, present but inert

Not switched on
Useful2 Signal5
Slack Integration Notable not in their notes

Session and message records now carry Slack tagging plumbing, but nothing turns it on.

A Slack connection flag, token env var and per-message ownership marker are wired through storage with no surface.

CLAUDE_CODE_SLACK_TAG_TOKEN
What

Session state and message records now carry the plumbing for connecting Claude Code to Slack tagging, including a connection flag, an environment variable for a token, and a per-message ownership marker. Every piece is wired through to storage and to the tool-selection path, but nothing in this build ever turns any of it on, and no tool or user-facing surface appears as a result.

Details
  • Interactive sessions carry a boolean slackTagConnected, defaulting to false at every point a session is created.
  • slackTagConnected can be set through the state-patch path and over the control protocol that SDK and IDE clients use, and is read by a status selector.
  • That same flag forms part of the key used to memoise the list of available tools, so flipping it would recompute which tools are offered.
  • A CLAUDE_CODE_SLACK_TAG_TOKEN environment variable is read for credentials.
  • Individual messages carry a slackTagOwnerTurn marker that is written through into stored transcripts, but the code that would set it is absent here.
  • None of these fields existed in the previous release.
Evidence

slackTagConnected, slackTagOwnerTurn

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
