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

mage-the-ascension 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mage: The Ascension

Seed, not scripture

The source buries this in a private fictional universe, manic stage-directions, and a named roster of example characters, repeated verbatim. Strip the furniture, keep the system. The example mages and the theatre are not the content; the Spheres, Traditions, and metaphysics are. And the system is a starting board, not a script — regrow each game on the player's own mage, their own paradigm, their own trouble. A recited example campaign is a dead one.

What it is

The content-pack for one specific game, built to plug into the generic engine in /solo-rpg. That skill is system-agnostic on purpose — it gives you the scene-prompt template, the Mystery+Danger+Dilemma triad, the resolution loop, and the GM toolkit, but no setting. This is the setting. Pour these Spheres, Traditions, and metaphysics into that engine and you can run Mage: The Ascension solo with depth. The two are designed to cite each other: engine here, fuel there.

The Nine Spheres (conceptual domains)

Magic in this game is organized by nine domains of reality a mage can perceive and bend; rated roughly from sensing, to affecting, to commanding. In plain terms:

  • Correspondence — space, distance, location, connection between places.
  • Time — perceiving and shifting the flow of past, present, future.
  • Mind — thought, perception, consciousness, mental contact.
  • Life — living organisms, health, growth, biological form.
  • Forces — energy: fire, electricity, gravity, light, sound, motion.
  • Matter — inanimate substance, its properties and transformation.
  • Prime — the primal energy (Quintessence) underlying all magic; creation, the pattern of magic itself.
  • Spirit — the spirit worlds, the Umbra, ghosts, the membrane between realms.
  • Entropy — chance, fate, decay, order and dissolution, probability.

The richness lives in combinations: Correspondence + Time as spacetime weaving; Life + Mind as biopsychic work; Prime + Entropy as fate-bending; Forces + Matter as elemental alchemy. When running, ask which one or two Spheres a desired effect needs, and narrate through that pairing.

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.
