Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00096 | $0.01513 |
| Opus 5 | $0.00048 | $0.00757 |
| Sonnet 5 | $0.00019 | $0.00303 |
| Haiku 4.5 | $0.00010 | $0.00151 |
Grade A, and why
unity-tilemap-2d scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity 2D Tilemap
Author and script tile-based 2D levels in Unity 6.3 LTS with the Grid/Tilemap system, the Tile
Palette, colliders, and runtime painting. Targets Unity 6.3 LTS (6000.3).
Package note: the core Tilemap (
Grid,Tilemap,Tile,TilemapCollider2D) is built in. Rule Tiles, Animated Tiles, and Tile Palette brushes live in the separate "2D Tilemap Extras" package (com.unity.2d.tilemap.extras) — install it via Package Manager before usingRuleTile.
When to use
- Use when laying out a 2D level by painting tiles, setting up a
Grid+Tilemap, adding collision to the map, using auto-tiling Rule Tiles, or generating/editing tiles from script. - Use when scenes contain a
GridwithTilemapchildren, or*.assettile/palette files.
When not to use: level design practice (pacing, blockout, layout principles) →
level-design. 3D tile/grid placement → Unity's own 3D tooling (ProBuilder / grid brushes; no dedicated skill here). The platformer character that
moves over the tiles → platformer / unity-physics.
Core workflow
- Create the grid: GameObject → 2D Object → Tilemap → Rectangular. This makes a
Gridwith a childTilemap(+TilemapRenderer). Use one Tilemap per layer (background, ground, foreground) and set each renderer's sorting. - Open the Tile Palette (Window → 2D → Tile Palette), drag in a sliced sprite sheet to
create
Tileassets, then paint with the brush tools. - Add collision to the solid layer:
TilemapCollider2D. For one merged collider (far cheaper and gap-free), also addCompositeCollider2D(+ aRigidbody2Dset to Static) and enable Used By Composite on the tilemap collider. - Auto-tile with Rule Tiles (2D Tilemap Extras) so edges/corners pick the right sprite automatically instead of hand-placing every variant.
- Edit at runtime via script with cell coordinates (
Vector3Int):SetTile,GetTile,SetTilesBlock, converting world↔cell with theGrid/Tilemap. - Verify in Play mode: confirm collisions (Physics Debugger), sorting order, and that
RefreshAllTilesran after bulk edits.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

unity-tilemap-2d is a skill published in the GitHub repository gamedev-skills/awesome-gamedev-agent-skills (952 stars, last pushed 2d ago), licensed Apache-2.0. It adds 96 tokens to every session and 1,513 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
assets-get-data
Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' to find the asset first.
gameobject-set-parent
Reparent a batch of GameObjects under a new parent in the currently opened Prefab or active Scene. Per-item failures are reported in the returned status string instead of aborting the batch. Use 'gameobject-find' to locate the GameObjects first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
profiler-save-data
Save a snapshot of profiler-derived stats (status + memory + rendering + script + frame capture) to a JSON file. Built-in Unity APIs only.
assets-shader-list-all
List all shaders available in the project assets and packages, sorted by name. Use this to discover a valid shaderName for 'assets-material-create'.
profiler-stop
Disable Unity's runtime profiler. Idempotent — calling when already disabled returns the current disabled state.
