## Why this exists
**A big MCP server is expensive to be connected to.** The full catalog costs a client **59,315 tokens** before it has asked for anything. Discovery mode replaces it with two tools and costs **356**.
**A drafter searches for `FILLET`, not `entity_fillet`.** Those command names appeared in no tool name or description — `df = 0` against a stock index, not badly ranked but *absent*. The fix was data: an authored corpus of **186 AutoCAD command names and 933 synonym phrases** covering all 204 tools. A test refuses to let a tool exist without one.

**Two rules worth knowing.** Every coordinate in and out of a tool is WCS on both engines — the one exception is TEXT `rotation`, which stays in the entity frame because a mirrored TEXT is mirror-imaged and no scalar angle expresses that. And never read vertices back and shoelace them: that loses **28.2%** of the area on a semicircular edge, silently. `analysis_measure_entity(handle)` reads the real geometry and states its own accuracy.
