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 | $0.00011 | $0.05472 |
| Opus 5 | $0.00005 | $0.02736 |
| Sonnet 5 | $0.00002 | $0.01094 |
| Haiku 4.5 | $0.00001 | $0.00547 |
Grade A, and why
unity-batch 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 2d 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 — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via
GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Unity Batch Skills
Batch workflow orchestration for query, preview, execution, reports, and async jobs.
POST /skills/batch — several skills, one HTTP call
This is an HTTP endpoint, not a skill: do not send skills_batch to POST /skill/<name>. It runs a sequence of ordinary skills inside one main-thread job, which removes one round-trip and one main-thread wakeup per step — the single largest efficiency lever in this protocol when you have more than two writes to make.
POST /skills/batch
{
"steps": [
{"skill": "gameobject_create", "args": {"name": "Cube", "primitiveType": "Cube"}},
{"skill": "component_add", "args": {"instanceId": {"$ref": "$0.instanceId"}, "componentType": "Rigidbody"}}
],
"continueOnError": false
}
| Body field | Type | Default | Meaning |
|---|---|---|---|
steps |
array | required | {skill, args} objects, executed in order. Max 50 — more returns 400 + SEMANTIC_INVALID; split into several calls. |
continueOnError |
bool | false |
false = fail-fast; true = record the failure and keep going. |
params |
object | none | Fills {"$param":"name"} placeholder nodes in step args (static substitution, resolved before $ref). |
Query: ?mode=dryRun validates every step without executing anything and never interrupts (the batch counterpart of the dryRun gate); ?mode=transactional is all-or-nothing with Undo rollback; ?diff=1 adds a net sceneDiff. ?mode=plan is not supported. Inter-step $ref ({"$ref":"$0.instanceId"}) and transactional details → SKILL_FULL.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.

unity-batch is a skill published in the GitHub repository Besty0728/Unity-Skills (1,695 stars, last pushed yesterday), licensed MIT. It adds 11 tokens to every session and 5,472 once invoked, about $0.0001 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.
