permissions

You can manage Claude Code permissions by modifying the `allow`, `ask`, and `deny` lists in the `~/.claude/settings.json` file. This Skill reads the file, detects your intent, validates input formats, and applies changes with safety checks.

The allow, ask, and deny lists in Claude Code control tool execution permissions. You can add entries to allow automatic execution, ask for user confirmation, or deny access completely, moving entries between these lists to enforce security boundaries.

To add a tool to the allow list, you provide the entry name, such as "mcp__new_tool__*", to the permissions manager. It validates the input format and applies the change to the `allow` array in your global settings file.

Yes, you can move permissions between the deny and allow lists interactively. The Skill modifies entries across these lists in `~/.claude/settings.json` based on your intent, applying the changes through a safe edit function rather than manual text editing.

Yes, Claude Code permission management works for restricting access. You can add specific read permissions to the allow list while keeping broader system access denied, ensuring only authorized actions and tools execute on targeted files.

Validating input formats when updating Claude Code settings prevents syntax errors in `~/.claude/settings.json`. The Skill performs validation checks before applying edits to ensure the JSON structure remains intact and the permission entries are correctly formatted.
