 Claude Docs reaches Claude Code as a claude.ai [connector](https://code.claude.com/docs/en/mcp.md#use-mcp-servers-from-claude-ai) rather than a command. When it's connected, `/mcp` lists it as `claude.ai Claude Docs`. A request for a document meant for other people then goes to Claude Docs instead of an artifact page: a spec, a proposal, or a write-up of the plan you worked through in the session.

Ask an Owner to add it to one of your roles at [**Organization settings > Roles**](https://claude.ai/admin-settings/roles).
 
 A cloud session is a Claude Code session that runs on cloud infrastructure instead of on your machine. By default it runs on infrastructure Anthropic manages, or on your organization's [self-hosted environment](https://code.claude.com/docs/en/self-hosted-environments) when routed there. The session keeps running after you close your laptop, and you can check on it or steer it from any device. It counts toward your plan's usage limits alongside the rest of your Claude and Claude Code usage, and there's no separate charge for the cloud VM.

 * **Exit zero**: if the script exits non-zero, the session fails to start. Append `|| true` to non-critical commands so an intermittent install failure doesn't block the session.
 * **Finish within five minutes**: keep the script's total runtime under roughly five minutes so the [environment cache](#environment-caching) can build. When setup takes longer than that, the environment isn't cached. Run independent installs in parallel with `&` and `wait`, and move any single download that won't fit into a [SessionStart hook](#setup-scripts-vs-sessionstart-hooks) that launches it in the background.

 * **Limits**: include at most eight different files, and keep `REVIEW.md` and the files it includes under 150,000 bytes combined. A file that would reach the byte limit is skipped whole, not cut short. The check run reports how many include lines it skipped for either limit.
-* **Links**: keep Markdown links at 64 or fewer across `REVIEW.md` and the files it includes. Links to `http`, `https`, or `mailto` addresses and to `#` anchors don't count.

 * **Merged copy**: merge the included file into the [branch `REVIEW.md` is read from](#which-branch-review-md-is-read-from). The review reads both from the same commit, never from the pull request's own changes.
 
+### Include a skill file
+
+To have reviews follow guidance you keep in a [skill](https://code.claude.com/docs/en/skills.md), include the skill's `SKILL.md` in your root `REVIEW.md`. Code Review doesn't run skills.
+
+Add `@` and the path to `SKILL.md`, in the form `.claude/skills/<folder>/SKILL.md`, on a line of its own:
+
+```markdown theme={null}
+# Review instructions
+
+Report at most five Nits per review.
+
+@.claude/skills/api-review/SKILL.md
+
+Treat any change under `migrations/` as Important.
+```
+
+Protect the [branch that `REVIEW.md` is read from](#which-branch-review-md-is-read-from), because Code Review includes a skill file only when it reads `REVIEW.md` from a protected branch. The skill file counts toward the limits of eight files and 150,000 bytes, and has its own limit of 30,000 bytes.
+
+#### Write a skill line that Code Review includes
+
+Use a folder name without spaces. A line with a space in its path stays in `REVIEW.md` as plain text, and the check run doesn't report it as a skipped include.
+
+If the `@` line for a skill breaks one of the rules below, Code Review doesn't include the skill from that line:
+
+* **Path**: write the path as `.claude/skills/<folder>/SKILL.md` from the repository root, with the skill's folder directly under `skills/`. Unlike a file name at the root, a path of this form that matches no file is skipped and counted.
+* **Source**: copy guidance from any other file under `.claude/`, or from a [bundled, personal, or plugin skill](https://code.claude.com/docs/en/skills.md#where-skills-live), into a file beside `REVIEW.md`. You can't include those directly.
+* **File**: commit `SKILL.md` as a regular text file. Code Review doesn't follow a symbolic link, whether the link is the file or a folder in its path.
+* **Size**: keep `SKILL.md` at 30,000 bytes or less, frontmatter included
+* **Count**: write at most eight skill lines. A repeated line counts again toward the eight.
+* **Blocks in `REVIEW.md`**: keep the `@` line out of code fences. Close every HTML comment and every `<pre>`, `<script>`, `<style>`, or `<textarea>` block above it.
+
+When Code Review skips a skill line for breaking the File, Size, Count, or Blocks rule, the check run's [message about skipped include lines](https://code.claude.com/docs/en/code-review-troubleshooting.md#the-check-run-mentions-review-md) counts it. The message appears only when the review applies `REVIEW.md` from a protected branch.
+
+#### Check what a review gets from a skill
+
+When the skill is included, a review gets the body of `SKILL.md` and nothing else from the skill, so check the skill against the list below.
+
+* **Frontmatter**: repeat in the body anything a review needs from the [frontmatter](https://code.claude.com/docs/en/skills.md#frontmatter-reference), for example the conditions that `description` gives for using the skill
+* **Injected commands**: write out what a [`!` command](https://code.claude.com/docs/en/skills#inject-dynamic-context) would supply. Code Review doesn't run the command, and replaces the whole line or block that holds it with a placeholder.
+* **Substitutions**: replace `$ARGUMENTS` and other [substitutions](https://code.claude.com/docs/en/skills.md#available-string-substitutions) with fixed text, because a review passes no arguments and leaves them as written
+* **Supporting files**: copy what a review needs into `SKILL.md`, because Code Review doesn't load scripts, linked files, or `@file` references
+* **Exclusions and Nit caps**: write instructions that exclude findings or cap Nits in `REVIEW.md` or a file beside it, not in the skill. Code Review doesn't accept a skill's text as the reason for either.
+* **Links to repository files**: state in words what a link or `@file` reference points to. The review sees the path as plain text or as a placeholder.
+
+If you edit the skill's `!` commands, `$ARGUMENTS`, or links, you also change how it works in Claude Code. If your team relies on those, copy the guidance into a file beside `REVIEW.md` and include that file in place of the skill.
+
+#### Characters that Code Review changes in skill text
+
+Code Review changes some characters in the skill's text, so your code samples reach a review in the form below.
+
+```text theme={null}
+In SKILL.md:       Use `items[0]`, never `List<String>`.
+The review reads:  Use ˋitems(0)ˋ, never ˋList< String>ˋ.
+
+In SKILL.md:       Run `ps | grep api` and ask @alice.
+The review reads:  Run ˋps ¦ grep apiˋ and ask @ alice.
+```
+
+Where a rule depends on one of those characters, state it in words too.
