Where does the skill search for my SKILL.md files?

It searches in your current working directory and the default global Claude skills directory located at ~/.claude/skills/.

Can this skill handle complex Bash subcommands?

Yes, it automatically formats commands into the required Bash(command:*) pattern to cover various sub-arguments and flags used within the skill.

Why do I need to update the allowed-tools section?

Claude Code requires explicit permission in the YAML frontmatter to execute specific Bash commands or access files outside the project directory for security reasons.

Will it overwrite my existing YAML frontmatter?

No, it parses your existing entries and only appends missing tools, then validates the final YAML to ensure the structure remains correct.

Does it support external skill-to-skill invocations?

Yes, it scans for skill references and ensures they are added to the allowed-tools list using the correct Skill(name) syntax.

Automatically scans and updates a skill's frontmatter to include all necessary tool permissions and Bash command declarations.

The Update Allowed Tools skill streamlines the development of Claude Code capabilities by performing an automated audit of a skill's source code and configuration. It intelligently identifies missing tool declarations—including specific Bash commands, file system access patterns, and external skill invocations—and automatically updates the YAML frontmatter to ensure the skill has the required permissions to execute. This utility is essential for developers who want to avoid the manual trial-and-error of defining security boundaries and tool access rules during the skill creation process.
