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.

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 | $0.00123 | $0.02175 |
| Opus 5 | $0.00062 | $0.01087 |
| Sonnet 5 | $0.00025 | $0.00435 |
| Haiku 4.5 | $0.00012 | $0.00217 |
Grade A, and why
rpgmaker-core 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 10d 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 — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RPG Maker Core Skill
This skill provides the safety foundation for all RPG Maker MV and MZ agent interactions. Load it first whenever you are working with any RPG Maker project. It teaches you how the project is structured, which rules you must never break, and where to find detailed reference docs.
All modifications you suggest are drafts for the developer to review and approve — never authoritative decisions. See the "All AI outputs are drafts" section below.
MV/MZ Detection
Before doing anything, determine the engine version.
| Manifest file present | Version |
|---|---|
Game.rmmzproject |
MZ |
Game.rpgproject |
MV |
| Both present | MZ (prefer MZ per spec) |
| Neither | Error — not an RPG Maker project |
Use scripts/lib/project_detect.py:
python -m scripts.lib.project_detect --project-path /path/to/project
# Outputs: MV or MZ
State the detected version at the top of every work session comment:
# Working on RPG Maker MV project at /path/to/project

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.

rpgmaker-core is a skill published in the GitHub repository nightquill/rpgmaker-agent-skills (23 stars, last pushed 4mo ago), licensed MIT. It adds 123 tokens to every session and 2,175 once invoked, about $0.0006 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
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components 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).
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
