Claude Code syncs claude.ai skills and plugins into the terminal
Claude Code 2.1.275 syncs a user's claude.ai skills and plugins into terminal sessions signed in with that account, with a setting to turn it off.
Anthropic’s Claude Code now carries the skills and plugins a user has enabled on their claude.ai account into terminal sessions signed in with that same account, so a setup made on the web no longer has to be rebuilt by hand at the command line.
The change shipped in Claude Code 2.1.275, released Sept. 17, 2026. It can be switched off with two settings, syncClaudeAiSkills: false and syncClaudeAiPlugins: false, set independently for skills and plugins.
What else shipped in 2.1.275
The same release added a send-now key, ctrl+enter or the chord ctrl+x ctrl+s, that interrupts whatever turn the model is running and sends every queued message at once. Sent and queued messages show in gray until the model receives them, according to the changelog.
Release 2.1.275 also extended plugin installation: /plugin install <plugin> --marketplace <source> now offers to add the named marketplace first if it is not already configured, then installs the plugin from it in the same command.
A fix followed one day later
Claude Code 2.1.276, published Sept. 18, 2026, fixed a regression that 2.1.275 had introduced, according to its release notes. Every request failed with a 400 error citing Input tag 'advisor_20260301' when the ANTHROPIC_BASE_URL environment variable pointed at a proxy or gateway rather than directly at Anthropic’s API. The fix landed one day after the feature that broke it shipped.
Analysis
Claude Code has spent the past several releases narrowing the gap between the web account and the terminal, and this one closes a specific piece of that gap: a skill or plugin turned on in a browser tab used to stay in the browser. Account-level sync means a team’s shared plugin list, or an individual’s personal skill set, now travels with the sign-in rather than the machine, which matters most for anyone who moves between a laptop and a remote session and does not want to reinstall the same tools twice.
The opt-out settings suggest Anthropic expects this to be a default some users will not want, likely teams running Claude Code against a curated, locked-down plugin set who do not want an account’s broader library showing up unannounced in a CI session. Shipping the toggle in the same release as the feature, rather than adding it after complaints, is the more notable design choice.
The regression is the more familiar story on this beat: a fast release cadence means a proxy-specific bug reaches anyone routing ANTHROPIC_BASE_URL through a gateway before it reaches Anthropic’s own traffic, and the fix follows within a day. For a tool that ships multiple point releases a week, that turnaround is closer to the norm than the exception.
