Claude Code v2.1.248

A "resume precheck" gate is handed to the VS Code extension

Under the hood
Useful2 Signal3
IDE Integration

A resume-precheck gate is now passed to the VS Code extension, on by default.

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: off

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: on

tengu_cobalt_harbor_notice Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

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

tengu_vscode_onboarding 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: on

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

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.

Details
  • Sits alongside tengu_vscode_review_upsell (fallback false), tengu_cobalt_harbor_notice (true) and tengu_vscode_onboarding (false).
Evidence

tengu_vscode_resume_precheck

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