Claude Code v2.1.251 ·

Skill proposals no longer behind a remote flag

Skill proposals no longer need a server flag; two environment variables now decide.

What

The tool that proposes new skills used to require a server-side flag that defaulted off. That check is gone, so availability now rests entirely on the environment variables CLAUDE_CODE_SKILL_PROPOSALS and CLAUDE_CODE_SYNC_SKILLS.

Details
  • With neither variable set, the tool stays unavailable; the difference is that Anthropic can no longer switch it on remotely.
Evidence

if (!x("tengu_propose_skills", !1)) return !1;

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

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

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed since Anthropic's documentation has since written up CLAUDE_CODE_SYNC_SKILLS, on Environment variables. | `CLAUDE_CODE_SYNC_SKILLS` | Set to `1` in non-interactive mode with the `-p` flag to make Claude Code download the skills enabled for your claude.ai account in that run and wait for the list of them, up to `CLAUDE_CODE_SYNC_SKILLS_WAIT_T… env-vars see the edit
Added since A small documentation edit on Environment variables touched a line naming CLAUDE_CODE_SYNC_SKILLS after this was published. | `CLAUDE_CODE_SYNC_SKILLS` | Set to `1` to download your enabled claude.ai skills into `~/.claude/skills/synced/` and resync every 10 minutes. Before it runs the first query, Claude Code waits up to `CLAUDE_CODE_SYNC_SKILLS_WAIT_TIMEOUT_M… env-vars see the edit
