Claude Code v2.1.242

Owner messages from MCP results can count as you speaking, currently dark

Not switched on
Useful2 Signal5
Projects Notable

Project owner messages fetched by a tool could be replayed as if you said them, currently dark.

Verified owner rows replay as user turns only when tengu_hearth_resolved_rows is exactly "full"; it defaults to "off".

Feature flag
tengu_hearth_resolved_rows Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

What

In Claude Code Projects, a tool result from the project fetch tools can now carry verified rows of messages from the project owner, and those get replayed into the conversation as turns that count as the user speaking. The remote setting tengu_hearth_resolved_rows defaults to "off" and this path requires the value to be exactly "full", so absent server config nothing here runs.

Details
  • Rows arrive under a new result metadata key, anthropic/hearth.rows, alongside the existing attachment-based path. The key does not appear in v2.1.241.
  • Replayed turns are flagged as harness-generated.
  • New telemetry event auto_mode_projects_owner_rows reports one of ok, invalid_rows, truncated or no_owner_rows; skipping the feature reports flag_not_full, deduplicated once per session.
  • The scan loop is wrapped so it iterates nothing unless the caller passes an enable flag, which the caller computes as a thread check plus the setting above. The setting also accepts "model_only", but only "full" turns this on.
Evidence

anthropic/hearth.rows

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