248Claude applies a built-in design skill when it builds an artifact, so pages get a deliberate palette, typography, and layout without extra prompting. Requires Claude Code v2.1.182 or later. That skill also looks for an existing design system in your project before choosing its own. Design tokens are the named color, typography, and spacing values your design system reuses. To keep artifacts consistent with your product's branding, record them where Claude can find them, such as the project's [CLAUDE.md](/docs/en/memory) or a theme file in your repository:

311311Each cloud session has a transcript URL on claude.ai, and the session can read its own ID from the `CLAUDE_CODE_REMOTE_SESSION_ID` environment variable. Use this to put a traceable link in PR bodies, commit messages, Slack posts, or generated reports so a reviewer can open the run that produced them.
312312
313Commits that Claude creates in a cloud session include a `Claude-Session: <url>` git trailer, and PR bodies include the session URL on its own line. To omit the trailer and the PR-body link, set [`attribution.sessionUrl`](/docs/en/settings-reference#attribution-sessionurl) to `false`. The setting requires v2.1.182 or later.

315315To include the session link in something other than a commit or PR, such as a Slack message Claude posts or a report file it writes, have Claude run the following command and use its output. The command converts the `cse_` prefix in the environment variable's value to the `session_` prefix that the transcript URL expects:

6464| `/code-review [low\|medium\|high\|xhigh\|max\|ultra] [--fix] [--comment] [pr#\|branch\|path]` | **[Skill](/docs/en/skills#bundled-skills).** Review the current diff, or a PR number, branch, or path you pass, for correctness bugs and cleanup opportunities. Pass `--fix` to apply findings, `--comment` to post them on the GitHub PR or GitLab merge request, or `ultra` to run a deep [cloud review](/docs/en/ultrareview). Posting to a GitLab merge request requires Claude Code v2.1.257 or later. With `ultra` on a `github.com` PR target, pass `--post` to preselect [posting the finished findings to the PR](/docs/en/ultrareview#post-findings-to-the-pull-request) in the launch dialog; `--post` requires Claude Code v2.1.227 or later. See [Review a diff locally](/docs/en/code-review#review-a-diff-locally) for the effort levels, targeting, and how it relates to `/simplify`. Alias: `/review` |
6565| `/color [color\|default]` | Set the prompt bar color for the current session. Available colors: `red`, `blue`, `green`, `yellow`, `purple`, `orange`, `pink`, `cyan`. Use `default` to reset, or run with no argument to pick a random color. When [Remote Control](/docs/en/remote-control) is connected, the color syncs to claude.ai/code. Also available in non-interactive mode (`-p`); requires Claude Code v2.1.205 or later |
6666| `/compact [instructions]` | Free up context by summarizing the conversation so far. Optionally pass focus instructions for the summary. See [how compaction handles rules, skills, and memory files](/docs/en/context-window#what-survives-compaction) |
67| `/config [key=value ...]` | Open the [Settings](/docs/en/settings) interface to adjust theme, model, [output style](/docs/en/output-styles), and other preferences. Pass one or more `key=value` pairs to set a setting directly without opening the interface, for example `/config thinking=false`. From v2.1.182, named shorthand keys are also accepted, such as `/config theme=dark` or `/config model=sonnet`. The `key=value` form also works in non-interactive mode (`-p`) and from the Claude mobile app via [Remote Control](/docs/en/remote-control). The `key=value` form can't turn on a setting that needs your confirmation in the panel, such as [`autoContinueAtUsageLimit`](/docs/en/interactive-mode#turn-automatic-continue-off), though it can turn one off. Run `/config --help` to list the keys it accepts. Alias: `/settings` |

6868| `/context [all]` | Visualize current context usage as a colored grid. Shows optimization suggestions for context-heavy tools, memory bloat, and capacity warnings. When the conversation exceeds the context window, the output includes a [warning](/docs/en/errors#context-exceeds-the-token-limit) showing how far over the limit you are and which command frees space. In [fullscreen mode](/docs/en/fullscreen), `/context` collapses the per-item breakdown to keep the grid visible. Pass `all` to expand it |
6969| `/copy [N]` | Copy the last assistant response to clipboard. Pass a number `N` to copy the Nth-latest response: `/copy 2` copies the second-to-last. When code blocks are present, shows an interactive picker to select individual blocks or the full response. Press `w` in the picker to write the selection to a file instead of the clipboard, which is useful over SSH |
7070| `/cost` | Alias for `/usage` |

310310 * User-invoked [skills](/docs/en/skills) and custom commands work. Include `/skill-name` in the prompt string and Claude Code expands it before running.
311311 * Built-in commands that only run in the terminal interface, such as `/login`, aren't available.
312312 * `/model`, `/effort`, `/fast`, `/color`, and `/rename` accept the value as an argument, for example `/model sonnet`, and `/mcp` with no argument prints a text summary of server status. These forms require Claude Code v2.1.205 or later and follow each command's [availability notes](/docs/en/commands#all-commands).
313 * To change a setting, pass `key=value` to `/config`, for example `/config thinking=false`. Requires Claude Code v2.1.181 or later.
313 * To change a setting, pass `key=value` to `/config`, for example `/config thinking=false`.
314314 * `/output-style <style>` switches [output styles](/docs/en/output-styles) and `/output-style` alone lists them. Requires Claude Code v2.1.269 or later.
