Recently changed surfaces

Your training data may describe Claude Code commands, flags, and terms that have since been renamed or removed. The "Available commands" list in your prompt is the authoritative list for this build. Use this file to translate stale terms when the user uses one or you're tempted to recommend one.

If a surface is in your training data but not in this file and not in the live build, it may have been removed since this file was last updated. WebFetch the changelog or the relevant docs page before telling the user it exists.

Removed slash commands

Removed	Replacement
/output-style	Open /config → Output style. Output styles still exist as a feature; only the dedicated command was removed
/pr-comments	Ask Claude in plain English to view pull request comments
/vim	Open /config → Editor mode
/extra-usage	Renamed to /usage-credits. The feature is unchanged

Removed CLI flags

Removed	Replacement
--enable-auto-mode	--permission-mode auto. Auto mode is also in the Shift+Tab cycle when it's available in the session

Removed keyboard and input shortcuts

Removed	Replacement
# prefix for quick memory entry	Ask Claude to edit CLAUDE.md, or use /memory

Renamed terms

Old term	Current term
Anthropic API	Claude API
Headless mode	Non-interactive mode (-p / --print flag). In Agent SDK contexts, just "Agent SDK"
Slash command (when referring to /config, /login, etc.)	Command
Extra usage	Usage credits
Custom commands	Skills (.claude/skills/). Custom commands as .claude/commands/*.md still work but skills are the documented surface
Claude in Slack (the earlier Slack app)	Claude Tag — Claude as a teammate in Slack, backed by remote Claude Code sessions; replaces the earlier app. See references/claude-tag.md
Tab to toggle extended thinking	Option+T (macOS) / Alt+T (Windows/Linux). Works on macOS without Option-as-Meta configuration

Commonly misremembered behavior

Your training data gets these wrong in a consistent direction. These corrections win over what you remember; fetched documentation still wins over this file.

• Models newer than your training data exist. Never tell a user a model they name doesn't exist; check the model configuration docs or the /model picker instead.
• Never state from memory which model an alias (opus, sonnet, haiku) resolves to. Resolution is per-release and per-provider, and an allowlist can pin it to an older version.
• ~/.claude/keybindings.json hot-reloads on save; don't tell users to restart. The file is an object with context-scoped binding blocks ({"bindings": [{"context": "Chat", "bindings": {...}}]}), not a flat key-to-command map. Action names come from the schema; don't invent them.
• The Shift+Tab permission-mode cycle is default → acceptEdits → plan → bypassPermissions → auto → default, where bypassPermissions and auto appear only when available in that session. dontAsk is never in the cycle.
• On macOS, Alt/Option chords like Alt+B and Alt+F work only when the terminal is configured to send Option as Meta. Don't claim an Option chord works in every terminal.
• CLAUDE_CODE_SUBPROCESS_ENV_SCRUB strips Anthropic and cloud provider credentials from subprocess environments and forces permission mode to default. It does not scrub arbitrary secrets such as GITHUB_TOKEN or NPM_TOKEN.
• Most but not all CLI options combine with -p/--print; --bg cannot.

Notes for stale advice

• Output styles are configured via /config, not /output-style.
• Auto mode is available via Shift+Tab or --permission-mode auto. On Bedrock, Vertex, and Foundry, auto mode availability may differ from first-party — check the provider's docs page.
• WebSearch is unavailable on Bedrock and gateway deployments. Don't tell a Bedrock user to "ask Claude to search the web."
• The gh CLI is recommended for GitHub operations, not WebFetch on api.github.com.
