## What This Repo Is
|
|
|
|
A technical book ("Claude's Hidden Toolkit") documenting 28 undocumented internal tools in Claude.ai's consumer interfaces. Fully reverse-engineered through systematic testing across browser, desktop app, and mobile app.

## Domain Knowledge
|
|
|
|
- **28 tools** documented with confirmed JSON schemas
|
|
- **3 platforms** with different tool inventories (browser: 21 tools, desktop: 22+32 MCP, mobile: 20+11 deferred)
|
|
- **Tool cards** in the Technical Annex follow a strict template (see Appendix C in the book)
|
|
- **Figures** are numbered sequentially fig_01 through fig_22 — all currently marked [Upcoming] pending screenshot capture
|
|
- **Response formats** are all empirically confirmed — no inferred markers remain
|
|
|
|
## Conventions
|
|
|
|
- Tool names in backticks: `web_search`, `event_create_v0`
|
|
- Platform tags on every claim: "Mobile App only", "Browser + Desktop only", "All"
|
|
- Version suffixes: `_v0` (initial/experimental), `_v1` (breaking upgrade)
|
|
- Confirmed vs unverified clearly marked — never speculate
|
|
|
|
## Architecture Context
|
|
|
|
The book documents a two-tier tool loading system:
|
|
- **Always-loaded tools**: injected into every conversation context (~17-22 depending on platform)
|
|
- **Deferred tools**: discovered at runtime via `tool_search` (mobile only, 11 consumer tools)
|
|
- **MCP tools**: discovered via `tool_search` on desktop only (32 integration tools)
|
|
|
|
The calendar system has a dual-layer architecture where Projects use MCP Connector tools with email-based IDs, while standard mobile chats use deferred consumer tools with numeric string IDs. The two layers are incompatible.
|
|
|
|
## Quality Gates
|
|
|
|
Before any content change:
|
|
1. Has the claim been tested on the relevant platform(s)?
|
|
2. Is the platform availability clearly stated?
|
|
3. Does the tool card follow the template structure?
|
|
4. Are figure numbers sequential with no gaps?
|
|
5. Is the response format marked as confirmed or unverified?
