rpg-artifact-creator

rpg-artifact-creator is a skill for Claude Code from vstrapasson/rpg-marketplace. It costs 261 tokens per session (3,800 once invoked), scanned A, original, MIT.

A tabletop role-playing game writing process for developing one important object, such as a relic, cursed item, crown, or legendary weapon. It creates a detailed profile covering the object’s history, motives, and cost without tying it to one game system.

In plain words
What is it for?
Use it to create a playable artifact dossier: where the object came from, what it wants, what it costs, and why the characters might seek, use, fear, or destroy it.
Why use it?
It turns a named object into something that can drive choices and events in a campaign instead of leaving it as a simple item description.

Token cost

What it costs to keep this loaded

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.

Security

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.

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.
