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 | $0.00261 | $0.03800 |
| Opus 5 | $0.00130 | $0.01900 |
| Sonnet 5 | $0.00052 | $0.00760 |
| Haiku 4.5 | $0.00026 | $0.00380 |
Grade A, and why
rpg-artifact-creator 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.

RPG Artifact Creator (system-agnostic, dark-leaning by default)
What this skill is for
Generate an artifact dossier — a deep, playable profile of a single legendary object: a relic, a cursed item, a regalia of office, a god-killing blade, the McGuffin the campaign turns on. This is the skill you reach for when an object that was named in a campaign, faction, or location dossier needs to become a thing the PCs hunt, wield, fear, dread carrying, or have to unmake.
This skill is system-agnostic — it focuses on provenance, will, and cost, not item levels, rarity, or runes, so it works for any system. (When mechanics are needed, point at the system's own relic/artifact rules rather than writing them — see references/artifact-frameworks.md §8.)
The default tone is dark-leaning (level 3 of 5): a gift good enough to keep, and a price steep enough to dread. See references/tone-spectrum.md.
The core idea — an artifact is a narrative node, not a powerful object
This is the bedrock that makes this skill different from the rest of the kit. A region coheres around geography, a city around its central question, a faction around its drive, a location around premise + ecology, an NPC around contradiction. An artifact coheres as a narrative node — a thing with edges running out to people, places, and the campaign's central truth, designed by its potential to move the plot (the Alexandrian) rather than by the moment it's found.
So this skill's job is not to describe a powerful object — it is to build a node that answers four questions: where did it come from, what does it want now, who is already reaching for it, and what changes when it enters play (references/artifact-frameworks.md §1). On top of that node sits the dark-leaning layer — an evocative gift and a staged price that escalates toward what the object wants. If your dossier reads like a powerful thing nobody is moving for that changes nothing when it appears, you wrote treasure, not a node — start over from the will and the desire-lines.
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.

rpg-artifact-creator is a skill published in the GitHub repository vstrapasson/rpg-marketplace (2 stars, last pushed 1mo ago), licensed MIT. It adds 261 tokens to every session and 3,800 once invoked, about $0.0013 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.

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).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
