346346## Pre-approve tools for skills

349 For project and personal skills, Claude Code applies the [`allowed-tools`](/docs/en/skills#pre-approve-tools-for-a-skill) frontmatter field in SDK sessions. You can also pre-approve tools for these skills through the `allowedTools` option (`allowed_tools` in Python) in your query configuration. Skills [synced from claude.ai](/docs/en/skills#how-claude-code-handles-the-frontmatter-of-a-synced-skill) follow their own frontmatter rules.
349 In SDK sessions, you can pre-approve tools for a project or personal skill with the skill's [`allowed-tools`](/docs/en/skills#pre-approve-tools-for-a-skill) frontmatter or with the `allowedTools` option (`allowed_tools` in Python) in your query configuration. If your organization sets [`allowManagedPermissionRulesOnly`](/docs/en/settings-reference#allowmanagedpermissionrulesonly) in managed settings, Claude Code ignores both. Skills [synced from claude.ai](/docs/en/skills#how-claude-code-handles-the-frontmatter-of-a-synced-skill) follow their own frontmatter rules.
