Heuristic logic analysis (labelled as heuristics, never auto-fixed): unreachable blocks, contradicted/redundant conditions, loops without exit, autorun pages that never end, shadowed pages, unused self switches, switches set but never read on the map, common event call cycles.

Append Event IR blocks at the end of a command list (map page, common event or troop page). No revision needed.

Preview-first: returns a change set (semantic + native diff, validation). Pass apply=true to commit immediately when the preview is clean.

Commit a previously previewed change set. Re-checks file revisions (rejects stale previews), backs up originals, writes atomically, and rolls back on failure. Requires --allow-write.

Structural differences between two records of the same category.

Create a database record with the next ID (max+1). Optionally start from a template (database_list_templates) and override fields (patch paths, e.g. "damage.formula"), collections (traits/effects/learnings/actions/dropItems/members) and noteTags. Returns the new ID.

Preview-first: returns a change set (normalized + native diff, validation incl. reverse references). Pass apply=true to commit immediately when the preview is clean.

DESTRUCTIVE: delete a record without renumbering. mode "clear" (default) replaces it with a blank record in the same slot; "truncate_last" removes the highest ID only. The preview lists every known reference. Apply with apply_changes + confirm.

Available database categories with record counts and max IDs.

Concise record summaries of a category (paginated). Blank (unnamed) slots are hidden unless includeBlank=true.

Record templates for database_create_record (template + templateParams).

Human-readable description of a page: conditions, graphic, trigger, priority, movement and the command flow with block ids.

Human-readable description of an event and ALL its pages (page priority explained).

Drop a pending change set (nothing on disk is touched).

Shortest walking route between two cells using the engine's passage rules. Returns route command names (move_up, ...) and a ready-to-use set_movement_route block. With from={eventId} the event is the mover (blocked by any non-through event). adjacent=true (default when to is an event) stops next to the target and turns to face it.

Reverse lookup: every known reference to a switch, variable, database record, common event, map, or map event (refKind "event" needs mapId). Includes low-confidence matches inferred from script text.

Full preview (diffs, diagnostics) of a pending change set.

A common event's trigger, condition switch and logic description (detailed=true also returns the Event IR).

Documentation of every Event IR block type, condition, route command and convention.

The Event IR of a command list with block ids, the revision token required by path-based edits, and whether the semantic view is complete (raw_command blocks are opaque but preserved).

Page settings plus readable logic (with block ids) and the list revision. Works for map event pages, common events and troop pages. detailed=true adds the full Event IR.

Raw native JSON of a page / common event / troop page, for debugging.

Event metadata and every page's settings (conditions, graphic, trigger, priority, movement), command counts, logic revisions and a short preview.

Text map of where the player can walk, using the engine's exact passage rules (directional tile bits, star tiles, wall tops, counters, blocking events). Returns an ASCII grid (2 characters per cell: walls drawn between cells), reachability from an origin (default: player start or the first transfer arrival), the separate walkable areas, and every event with its active page and whether the player can trigger it. Works without image support.

Map metadata (size, tileset, display name, note) and a summary of every event.

Commands and arguments declared in a plugin's annotation header (js/plugins/.js, read as text, never executed). Schemas are INFERRED from annotations; use them to author plugin_command blocks without inventing names.

Project root, detected engine/editor version, write mode, available data files and plugin count. Call this first.

Facts about one or more cells: tile ids per layer (sheet, autotile kind/shape, flags), blocked sides, exits, shadow, region, terrain tag, ladder/bush/counter/damage, events on it, reachability, and free (exit + no event + reachable): use it to check spots before placing NPCs or transfer destinations.

PNG image of a map (or a region) as the game draws it: tile layers with real autotiles, shadows, event sprites, plus a coordinate grid with x/y axis labels, event id boxes (colored by trigger), the player start (S) and transfer arrivals (T). Overlays: passability (blocked cells + walls), reachable (from the player start, a transfer arrival or reachableFrom), regions. Use it to understand the layout before placing events; use get_map_passability for exact walkability.

Reorder pages: order lists current pageIndexes in their new order (a permutation). Changes which page wins when several are active.
