Review the instructions the agent will receive before you install.

Context

Claude Code has a set of built-in tools that are always available, separate from MCP server tools. Users may want to see what built-in tools are available for reference.

Tools denied via permissions.deny in settings are removed from the session entirely — they never appear in the tool list, not even as deferred tools. So the live tool list alone under-reports what the harness ships: a denied tool looks identical to a tool that doesn't exist. Read the settings files to tell the two apart.

Your task

  1. Read the permissions.deny array from each settings file that applies, in order: ~/.claude/settings.json, .claude/settings.json, .claude/settings.local.json. Collect bare tool-name entries (e.g. NotebookEdit); ignore scoped ones like Bash(rm -rf /*:*), which gate arguments rather than the tool.
  2. List all built-in Claude Code tools (excluding MCP tools that start with mcp__) — both the ones available this session and the ones denied by those settings.

For each tool, provide:

  • Tool name in backticks
  • Brief description (one line)
  • — disabled (deny: <settings file>) suffix if it was denied

Organize by category:

  • File Operations
  • Execution & Shell
  • Web Access
  • Task Management
  • Integration

Deferred tools (schemas loaded on demand via ToolSearch) are available — list them normally, not as disabled.

Use compact format with minimal formatting.
