# AGENTS.md — Godot-AI-Tilemap
- A **Godot-MCP extension**: MCP tools for Godot's built-in `TileMapLayer` node (Godot 4.3+, the modern
- replacement for the deprecated `TileMap`) and its `TileSet`. Shipped as a **source-only NuGet package**
- (`com.IvanMurzak.Godot.MCP.Tilemap`) that compiles inside the consumer's Godot project against the consumer's
- own GodotSharp. Created from
- [`Godot-AI-Tools-Template`](https://github.com/IvanMurzak/Godot-MCP/tree/main/templates/extension). The packaging recipe is
- the load-bearing detail — read `docs/source-only-nuget-recipe.md`.
+ A **Godot-MCP extension** for Godot's built-in `TileMapLayer` node (Godot 4.3+, the replacement for the
+ deprecated `TileMap`) and its `TileSet`, shipped as an **RQL module**: it adds no MCP tools, only what the core
+ `rql-query` / `rql-mutate` / `rql-schema` tools need to paint layers (used-cell rows, `SetCell` / `EraseCell` /
+ `Clear`, validation, an agent guide rendered into the core `godot-rql` skill). A **source-only NuGet package**
+ (`com.IvanMurzak.Godot.MCP.Tilemap`) compiled inside the consumer's Godot project against the consumer's own
+ GodotSharp; the packaging recipe is in `docs/source-only-nuget-recipe.md`.
## Layout
- - `src/Godot-AI-Tilemap/` — the source-only package (`Godot.NET.Sdk`):
- - `Runtime/Tools/` — `Tool_Tilemap.cs` (the `[AiToolType]` partial class), `Tool_Tilemap.Ids.cs` (all
- tool-id consts, pinned by tests).
- - `Runtime/Tilemap/` — pure-managed cell / atlas-coordinate parsing + validation (`TileCell`,
- `TilemapValidation`, `TileMapLayerInfo`), all unit-tested.
- - `Editor/Tools/` — one file per editor tool (`Tool_Tilemap.<Name>.cs`) + shared helpers in
- `Tool_Tilemap.Editor.cs`; all behind `#if TOOLS`.
- - `build/com.IvanMurzak.Godot.MCP.Tilemap.props` — source-injection props, auto-imported by NuGet in the
- consumer; MUST stay named `<PackageId>.props`.
- - `tests/Godot-AI-Tilemap.Tests/` — xUnit specs for the pure-managed sources only (no Godot binary).
- - `tests/e2e/` — live `run-tool` E2E: the tool list `e2e-tools.json`, driven by `run_tool_e2e.py`.
- - `testbed/Tilemap-Testbed.csproj` — consumer `Godot.NET.Sdk` project restoring the local-packed package; its
- `dotnet build` is the source-injection proof.
+ - `src/Godot-AI-Tilemap/Editor/Rql/` — the module:
+ - `TilemapModule.cs` — the `IRqlModule` (Order 100, `#if TOOLS`): the adapter and the guide.
+ - `Godot_TileMapLayer_Adapter.cs` — `usedCells`, `usedCellCount` and the cell calls (`#if TOOLS`).
+ - Pure-managed, NOT behind `#if TOOLS`: `TilemapRules.cs` (validation), `TilemapGuide.cs` (the guide),
+ `TilemapCellRow.cs` (the read-only `usedCells` row).
+ - `src/Godot-AI-Tilemap/build/com.IvanMurzak.Godot.MCP.Tilemap.props` — source-injection props, auto-imported by
+ NuGet in the consumer; MUST stay named `<PackageId>.props`.
+ - `tests/Godot-AI-Tilemap.Tests/` — xUnit (no Godot binary): rules, guide examples parse, the module's member
+ table (GodotSharp metadata, `TOOLS` defined), and the e2e manifest runs every guide example.
+ - `tests/e2e/e2e-tools.json` — the live calls (`rql-*`), driven by `scripts/extension_e2e.py` from the monorepo suite.
+ - `testbed/` — consumer project restoring the local-packed package (injection proof) and `e2e-tileset.tres`, the
+ empty TileSet fixture the e2e assigns (copied to the live project root).
- `commands/` — `bump-version`, `update-core`, `init` (`.ps1` + `.py`), `get-version.ps1`.
- CI and publishing are centralized in the monorepo; see `../../docs/EXTENSION-MONOREPO.md`.
- - `docs/` — `source-only-nuget-recipe.md` (the packaging recipe + consumer story); `ci.md` (workflows, version
- gate, multi-Godot matrix, NuGet publishing setup).
-
- ## Tools
+ ## Critical invariants
- Ids live in `Runtime/Tools/Tool_Tilemap.Ids.cs` (the source of truth). Current tools: `tilemap-create`,
- `tilemap-set-tileset`, `tilemap-set-cell`, `tilemap-erase-cell`, `tilemap-get-used-cells`, `tilemap-clear`.
+ - **RQL surface.** Everything is registered by `TilemapModule` and documented in `TilemapGuide` (topic
+ "Tilemap"). Every guide example runs, in order, in `tests/e2e/e2e-tools.json` (xUnit-asserted).
+ - **Validate, never clamp.** `SetCell` rejects a negative source id (erase with `EraseCell`), atlas coordinate or
+ alternative before anything changes. The calls are on the layer itself, so the core undo snapshot covers its
+ cells (`tile_map_data`).
+ - The module uses only Godot, `com.IvanMurzak.Rql` and the BCL, never core-addon types (the authoring build has
+ no core). Undo, dirty marking and saving come from the core's mutation hooks.
## Build / test (no Godot binary)
```bash
- dotnet build src/Godot-AI-Tilemap/Godot-AI-Tilemap.csproj # source-only package compiles tools
+ dotnet build src/Godot-AI-Tilemap/Godot-AI-Tilemap.csproj -c Debug # the module (#if TOOLS included)
dotnet test tests/Godot-AI-Tilemap.Tests/Godot-AI-Tilemap.Tests.csproj
- dotnet pack src/Godot-AI-Tilemap/Godot-AI-Tilemap.csproj -p:Version=0.0.0-ci -o local-nuget
- dotnet build testbed/Tilemap-Testbed.csproj # consumes the local package (injection proof)
```
- `Godot.NET.Sdk` supplies GodotSharp from NuGet, so build/test/pack and the source-injection proof need no
- Godot install (the testbed build is a faithful proxy for `godot --build-solutions`). CI proves the recipe
- across Godot 4.3 / 4.4 / 4.5 (the central monorepo SDK matrix). `dotnet pack` reuses the **global NuGet
- cache** for an already-cached version: when re-packing the same `Version`, clear
- `~/.nuget/packages/com.ivanmurzak.godot.mcp.tilemap/<ver>` (or pack a unique version) before re-restoring the
- testbed, or you silently build the stale cached source.
+ The live suite (one headless editor for every module) is `python scripts/test_extensions.py` from the monorepo
+ root. `dotnet pack` reuses the **global NuGet cache** for an already-cached version: when re-packing the same
+ `Version`, clear `~/.nuget/packages/com.ivanmurzak.godot.mcp.tilemap/<ver>` (or pack a unique version).
## Conventions
- - Root namespace `com.IvanMurzak.Godot.MCP.Tilemap`. Every `.cs` starts with the Apache-2.0 header.
- - Pure-managed code (no Godot native API) → `Runtime/` (outside `#if TOOLS`, unit-testable); editor-driving
- tools → `Editor/` (behind `#if TOOLS`, every Godot call via `MainThread.Instance.Run(...)`, E2E-verified).
- - Godot types that wrap a native object (`Node`, `Resource`, `NodePath`, `SceneTree`) P/Invoke on
- construction, so they must never be touched from the no-Godot xUnit host — keep them out of `Runtime/`.
- - The package declares ONLY the `com.IvanMurzak.McpPlugin` / `com.IvanMurzak.ReflectorNet` min-version deps;
- **GodotSharp must never become a package dependency** (CI asserts the nuspec). Keep the MCP pins in lockstep
- with the core Godot-MCP addon; bump with `commands/update-core.ps1`.
- - One `[AiToolType] partial class Tool_Tilemap`; one `[AiTool]` method per partial-class file. Add every new
- pure-managed source to the test csproj `<Compile Include>` list so it is unit-tested.
+ - Root namespace `com.IvanMurzak.Godot.MCP.Tilemap`. Every `.cs` starts with the Apache-2.0 header and
+ `#nullable enable`.
+ - The package declares only the `com.IvanMurzak.McpPlugin` / `ReflectorNet` / `Rql` pins (equal to the core's); **GodotSharp must
+ never become a package dependency** (CI asserts the nuspec). Bump them with `commands/update-core.ps1`.
