Skill Pre-Approval - Claude Code

Skill pre-approval lets you grant tool permissions upfront when a skill runs, so the skill's routine actions don't trigger prompts.

What it does

Declare a pre-approval list in the skill's frontmatter. When the skill fires, those tool invocations skip the permission dialog. The rest of the session still follows normal rules. This is how well-tested skills stay fast without forcing users into global allow modes.

When to use it

• Skills with a fixed, well-understood set of tool calls.
• Repeatable workflows where prompts would break flow.
• Team-shipped skills where you've already vetted the behavior.
• CI-adjacent skills that must not hang on approvals.

Gotchas

• Pre-approval widens the blast radius if the skill is compromised. Review changes carefully.
• Grants are scoped to the skill's execution, not the whole session. Good defense-in-depth.
• Permissions still can't override protected paths.
