Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00073 | $0.06465 |
| Opus 5 | $0.00036 | $0.03232 |
| Sonnet 5 | $0.00015 | $0.01293 |
| Haiku 4.5 | $0.00007 | $0.00647 |
Grade A, and why
isometric-ops 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 8d 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 — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Isometric Operations
Create, refine, compose, and export isometric illustrative assets for websites and games — end to end. This skill covers the exact projection math, the vector/CSS/SVG and three.js generation routes, the pixel-art and Blender pre-render pipelines, engine tilemap integration, the AI-generation-with-structure-control workflow, asset sourcing with licence discipline, and the companion iso-studio scene composer (a standalone app that grew out of this skill). Every constant is derived and machine-checked; every workflow is runnable; every claim is sourced in its reference file.
Boundary — what this skill does NOT own. General three.js / creative-coding scaffolding lives in
genart-ops; app- and game-scale three.js (GLTF pipeline, react-three-fiber,InstancedMesh) lives in thethreejs-opsskill. Colour science and perceptual (OKLCH) ramp construction live incolor-ops.isometric-opsowns only the isometric delta — it cross-links those siblings, it never restates them. Detail lives in the reference files below: this router points, it does not duplicate.
1. The projection decision — always step zero
Choose the projection before you draw, generate, or model anything. This is not a deferrable stylistic preference: it fixes the grid math, the tile aspect ratio, the camera rig, and the anti-aliasing strategy for the entire pipeline downstream. Changing it later means re-cutting every asset.
| Job | Projection | Ground-axis angle | Tile / face rule | Where |
|---|---|---|---|---|
| Web / vector illustration, diagrams, icons, hero art | True isometric | 30° (all three axes 120° apart) | all axes foreshorten equally; smooth vector edges ignore pixel stepping | projection-math.md §1, svg-vector-generation.md, css-isometric.md |
| Game tiles, tilemaps, sprite worlds, most "isometric" games | 2:1 dimetric (commonly called isometric in games) | 26.565° = arctan(1/2) | integer 2px:1px steps tessellate; tileW = 2·tileH |
projection-math.md §2, coordinates-depth.md, engine-integration.md |
| Hand-placed / library pixel-art primitives (cubes, bricks, slopes) | Pixel-neat 1:2 | 22.6° (obelisk.js pixel-dot pattern) | 1:2 pixel dot stepping avoids staircasing at primitive-drawing level | projection-math.md §7, pixel-art-workflow.md |

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.
- 8d ago First seen · 320 lines · 73 tokens per session scan A 21ebdea7e994
isometric-ops is a skill published in the GitHub repository 0xDarkMatter/claude-mods (33 stars, last pushed 16d ago), licensed MIT. It adds 73 tokens to every session and 6,465 once invoked, about $0.0004 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.
