What

When the claude-vscode MCP connection comes up, Claude Code passes the extension a snapshot of feature-gate values. This release adds tengu_vscode_resume_precheck to that snapshot, with a compiled fallback of true, so with no server value the extension is told the precheck is on. The CLI never branches on it, so whatever the precheck does lives entirely in the extension.

Feature flag
tengu_vscode_resume_precheck 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.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.248: on

tengu_vscode_review_upsell Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.248: off

tengu_cobalt_harbor_notice On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

What has happened since
Flag reading moved The flag server now returns on for tengu_cobalt_harbor_notice, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
