166166* **Reserved name `anthropic-skills`**: outside a plugin, a skill folder or command file whose name is `anthropic-skills` or starts with `anthropic-skills:` doesn't load. See [Names reserved for synced skills](#names-reserved-for-synced-skills).
167167* **Characters in the name**: outside a plugin, a skill folder doesn't load when its name has a character such as a zero-width space or `<`. See [Characters a skill name can't hold](#characters-a-skill-name-cant-hold).
168168* **Command files**: a Markdown file in `.claude/commands/` is the older format and still works. It supports the same [frontmatter](#frontmatter-reference) except `name` and `paths`. To find the name you type to invoke it, see [How a skill gets its command name](#how-a-skill-gets-its-command-name). Prefer a skill for new work, since skills also support [supporting files](#add-supporting-files).
169* **Skill folder as a plugin**: add a `.claude-plugin/plugin.json` to a skill folder and it loads as a [plugin](/docs/en/plugins/loading#plugins-shared-through-a-repository) named `<name>@skills-dir`, so it can bundle agents, hooks, and MCP servers. In a project's `.claude/skills/`, this requires accepting the workspace trust dialog first.
169* **Skill folder as a plugin**: add a `.claude-plugin/plugin.json` to a personal or project skill folder and Claude Code can load it as a [plugin](/docs/en/plugins/loading#plugins-shared-through-a-repository) named `<name>@skills-dir` with its own agents, hooks, and MCP servers. In a project's `.claude/skills/`, this requires accepting the workspace trust dialog first, and in either location it requires that your administrator hasn't [blocked skills-directory plugins](/docs/en/plugins/loading#skills-directory-plugins-blocked-by-managed-settings).

395395| `context` | No | Set to `fork` to run in a forked subagent context. See [Run skills in a subagent](#run-skills-in-a-subagent). |
396396| `agent` | No | Which subagent type to use when `context: fork` is set. |
397397| `background` | No | Only applies with `context: fork`. Set to `false` to wait for the forked subagent's result in the turn that invoked the skill, instead of [running it in the background](#run-skills-in-a-subagent). Default: `true`. Requires Claude Code v2.1.218 or later. |
398| `hooks` | No | Hooks that Claude Code registers when the skill is invoked and keeps running for the rest of the session. See [Hooks in skills and agents](/docs/en/hooks#hooks-in-skills-and-agents) for the configuration format and the `once` option. |
398| `hooks` | No | Hooks that Claude Code registers when the skill is invoked and keeps running for the rest of the session. See [Hooks in skills and agents](/docs/en/hooks#hooks-in-skills-and-agents) for the configuration format, the `once` option, and the [limits on skill hooks](/docs/en/hooks#limits-on-skill-hooks). |
399399| `paths` | No | Glob patterns that limit when this skill is activated. Accepts a comma-separated string or a YAML list. When set, Claude loads the skill automatically only when working with files matching the patterns. Patterns are relative to Claude's current working directory, and files outside that directory don't match. Uses the same glob format as [path-specific rules](/docs/en/memory#path-specific-rules). |
400400| `shell` | No | Shell to use for `` !`command` `` and ` ```! ` blocks in this skill. Accepts `bash` (default) or `powershell`. Setting `powershell` runs inline shell commands via PowerShell when the [PowerShell tool](/en/tools-reference#powershell-tool) is enabled: it's on by default on Windows without Git Bash, on by default with Git Bash for claude.ai and Console accounts, and needs `CLAUDE_CODE_USE_POWERSHELL_TOOL=1` in Amazon Bedrock, Google Cloud's Agent Platform, and Microsoft Foundry sessions and on macOS, Linux, and WSL. Set it to `0` to turn the tool off. |
401401| `metadata` | No | Free-form YAML map for your own key-value data, such as entitlement or catalog fields, read by your own tooling from `SKILL.md`. Claude Code doesn't act on its contents, and drops a value that isn't a map. Don't reuse frontmatter field names such as `paths` as keys. |
