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 | $0.00067 | $0.01233 |
| Opus 5 | $0.00034 | $0.00616 |
| Sonnet 5 | $0.00013 | $0.00247 |
| Haiku 4.5 | $0.00007 | $0.00123 |
Grade A, and why
unity-yaml-format 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity YAML Format
Use this skill when working directly with Unity text-serialized files rather than higher-level C# or Editor APIs.
First Pass
- Read references/source-summary.md.
- Identify the file type and intent: inspect, explain, diff, repair, or minimally edit.
- If the task involves object or component type numbers, read references/class-id-reference.md.
- If the task involves
fileID,guid,type, script links, or external asset links, read references/reference-semantics.md. - If the task involves hand-editing, read references/examples.md before changing anything.
Working Rules
- Treat UnityYAML as a Unity-specific serialization format, not as generic full YAML.
- Prefer the Unity Editor for broad structural changes; use manual edits only for narrow, justified repairs to existing text-serialized files.
- Keep edits as small and local as possible.
- Preserve existing indentation, document order, anchors,
fileIDlinks, and scalar style unless the task requires otherwise. - Explain reference relationships explicitly when reviewing a file.
Gotchas
- UnityYAML is a custom subset and does not support the full YAML specification.
- Unity docs warn against externally producing or editing UnityYAML files; only make manual edits when the narrow reference or scalar repair is justified.
- Comments are not supported by UnityYAML.
- Multi-line plain scalars require deeper indentation on continuation lines.
- UTF-8 characters are decoded only inside double-quoted scalars.
- Chomping indicators, complex mapping keys, raw top-level block sequences, and arbitrary YAML tags are not supported.
- Unity scene and prefab files are multi-document files where each serialized object starts with
--- !u!<classID> &<fileID>. classIDandfileIDhave different roles:classIDidentifies the object type, whilefileIDidentifies one object instance inside the file.- In external references,
guididentifies the target asset file andfileIDidentifies an object local to that asset; preservetypeas part of the serialized reference tuple without guessing a new value. type: 2commonly indicates a non-built-in Unity asset whose contents are text-serialized in UnityYAML, such as a project material or similar asset.- A
GameObjectreferences attached components throughm_Component, and components usually point back throughm_GameObject. - Script components use class ID
114(MonoBehaviour) and often require script references to remain intact. - Floats may appear in decimal or IEEE 754 hexadecimal forms; when Unity writes
0x...(decimal)the hex value is the parsed value, and manual edits should usually replace it with a plain decimal. - References such as
{fileID: 0}often mean a null-like Unity reference, not a missing parse failure by itself.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-yaml-format is a skill published in the GitHub repository sator-imaging/suggest-skills (0 stars, last pushed today), licensed Apache-2.0. It adds 67 tokens to every session and 1,233 once invoked, about $0.0003 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.
