Tools

elin_guide	Start here. Turns an intent ("add a new item", "change how doors work") into a route: ordered steps, which wiki articles to read, which source sheets are involved, which game types to inspect.
elin_wiki	Full-text search across the Elin Modding Wiki (EN / ZH / JA).
elin_doc	Read a wiki article; long ones return a section outline first.
elin_sheet	Source sheet columns, read straight from the game's own `Source*.Row` classes — cannot go stale.
elin_ids	Which ids actually exist for a category, searchable by EN / JP / CN name.
elin_scaffold	Generate a mod skeleton — a compilable BepInEx/Harmony project, or the layout for a data-only mod.
elin_find	Find a type or member by name or substring.
elin_outline	Every member of a type with signatures, no bodies.
elin_hierarchy	Inheritance and implementation, both directions.
elin_callers	Where a method is called from — check this before patching, to learn when the target actually runs.
elin_read	Read one member's implementation, sliced by line from the index.
elin_versions	Which game versions are indexed.

Prose comes back in English, 简体中文 or 日本語 — pass lang.

Why not just grep the source

Elin's source has several 100 KB+ god classes — reading Trait.cs whole costs roughly 85k tokens and buys you almost nothing. This server has no whole-file read at all: elin_read only accepts names the index returned, and caps a single call at 400 lines. Locating a method costs a few hundred tokens instead of tens of thousands.
