Documents 24 tools found in Claude.app binary (app.asar/index.js) that are not listed in the deferred tools system-reminder. Organized into 7 categories: - Widget Tools (2): inline SVG/HTML rendering via @ant/imagine-server - Preview Tools (13): dev server and browser preview in code tasks - Computer Use (1, 13 actions): desktop automation via screenshot-then-act - Terminal & Roots (2): IDE-plugin-only terminal reader and MCP roots - Office Add-in (5): Excel/Word/PowerPoint integration via Claude add-in - Conversation (1): internal compaction service, not user-callable - Feature Flags & Codenames: flags, codenames, Swift APIs, config keys Each tool includes verification status (CONFIRMED/NOT FOUND/UNTESTED), parameter schemas, and session-type availability matrix. Tone cleanup: removed speculative language per CLAUDE.md style guide. States facts from binary analysis, marks unverified claims explicitly.

# Hidden / Unlisted Tools
|
|
|
|
Tools found in the Claude.app binary that are not listed in the deferred tools system-reminder. These tools are gated by platform, feature flags, or session type. Many are visible to users in the UI but are not exposed to the AI assistant via `tool_search` or MCP tool registration.
|
|
|
|
**Discovery method:** Extracted `app.asar`, searched `index.js` for tool registration patterns not in the deferred tools list.
|
|
|
|
**Last updated:** 2026-03-19
|
|
|
|
**Verified across:** Dispatch, Cowork task, code task, Claude Code CLI, Claude Desktop main chat, claude.ai web chat
