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.

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 | $0.00030 | $0.00754 |
| Opus 5 | $0.00015 | $0.00377 |
| Sonnet 5 | $0.00006 | $0.00151 |
| Haiku 4.5 | $0.00003 | $0.00075 |
Grade A, and why
using-isometric-skills 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 11d 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.

Using Isometric Skills (Router)
Overview
This is the meta-skill. Isometric games fail when you jump straight into code or art without picking the right workflow. This skill maps an incoming request to the exact specialized skill that should handle it, in the correct order: art direction -> asset generation -> asset processing -> engine -> gameplay -> polish.
When to Use
- The user asks for anything isometric and you are not sure which skill applies.
- You are tempted to free-style a renderer, tile, or sprite without a workflow.
- A task spans multiple stages (art + engine) and needs sequencing.
Process
- Classify the request into one phase: Art Foundations, Asset Generation, Asset Processing, Engine & Rendering, Gameplay, or Polish.
- Open the matching skill from the table below and follow it exactly. Do not improvise.
- If the task spans phases, run skills in pipeline order (art -> assets -> processing -> engine -> gameplay -> polish).
- Lock art direction FIRST. Every asset skill depends on a single agreed style sheet.
- Return to this router whenever the user changes scope.

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.

using-isometric-skills is a skill published in the GitHub repository 0xheycat/isometric-game-skills (15 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 754 once invoked, about $0.0002 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 2026-08-31.
