disableBundledSkills Setting / Claude Code v2.1.169

What

A new settings option that removes all skills and workflows that ship bundled with Claude Code. Built-in slash commands remain typable but are hidden from the model. Your own plugins, .claude/skills/, and .claude/commands/ are unaffected.

Usage

// In settings.json or settings.local.json:
{
  "disableBundledSkills": true
}

Or via environment variable:

CLAUDE_CODE_DISABLE_BUNDLED_SKILLS=1 claude

Details

Equivalent to setting CLAUDE_CODE_DISABLE_BUNDLED_SKILLS=1
Affects skills like /review, /init, /deep-research, and now /design-sync, but NOT user-created commands in .claude/
The setting is documented inline: "Disable the skills and workflows that ship with Claude Code: bundled skills and workflows are removed entirely; built-in slash commands stay typable but are hidden from the model."

Evidence

Settings schema addition (search for "disableBundledSkills") — added to settings schema at line ~11677

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

Names in this entry

settingdisableBundledSkills
Turn off the skills and workflows included with Claude Code
envCLAUDE_CODE_DISABLE_BUNDLED_SKILLS
Set to 1 to disable the skills and workflows included with Claude Code: bundled skills and workflows are removed entirely, while built-in commands like /init stay typable but are hidden from the model. /doctor stays typable like the built-in commands; hide it with DISABLE_DOCTOR_COMMAND instead. Skills from plugins, .claude/skills/, and .claude/commands/ are unaffected. Equivalent to the disableBundledSkills setting
slash/review
Alias of /code-review: reviews the current diff, or a PR number, branch, or path you pass, such as /review 1234, and takes the same effort levels and flags. With no level given, the review reuses the last low through max level you typed; see Review a diff locally for the exact rules. For a deep cloud review, use /code-review ultra. Before v2.1.223, /review was a separate command that ran a single-pass, read-only review of a GitHub pull request by number, listing open PRs to pick from when run with no argument; from v2.1.186 through v2.1.201, it ran the same multi-agent engine as /code-review medium
slash/init
Initialize project with a CLAUDE.md guide. Set CLAUDE_CODE_NEW_INIT=1 for an interactive flow that also walks through skills, hooks, and personal memory files. If /init finds OpenAI Codex or Google Gemini CLI configuration, it offers to carry it over with /import
slash/deep-research
Workflow. Fan out web searches on a question, fetch and cross-check sources, and synthesize a cited report
slash/design-sync
Skill. Convert your repo's React design system and upload it to Claude Design, so designs it produces use your real components. Optionally name the design system, for example /design-sync Acme DS. A first-time sync verifies every component and can take a few hours on a large repo. Available on the Anthropic API. It needs claude.ai, which the CLI doesn't contact on Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, or Claude Platform on AWS, or through a Claude apps gateway, so the command is unavailable there

Anthropic's note

Upstream's own release notes for v2.1.169 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.

Added a disableBundledSkills setting and CLAUDE_CODE_DISABLE_BUNDLED_SKILLS environment variable to hide bundled skills, workflows, and built-in slash commands from the model
