prometheus

A tool that turns a difficult historical concept, institution, or proper name into a short public-facing definition card. The card explains what it is, what distinguishes it, and when and where it belonged.

In plain words
What is it for?
Use it to define terms from a historical paper and create an attribution-style SVG card with a plain-language explanation and historical context.
Why use it?
It makes specialist historical terms understandable without reducing them to an imprecise translation.

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

prometheus 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.

What it actually says

prometheus

The work this skill is for

prometheus steals the fire of definition.

It takes one concept from a historical text and renders it into a compact, public-facing card: genus, differentia, plain-language gloss, institutional and temporal grounding, and one conceptual spark bright enough to hold in the mind.

The card is not a poster full of effects. It is a definition made visible.

Input

Target: $ARGUMENTS

  • concept name (for example 三司, 均田, 经世, 清议) → define it directly
  • workspace directory → read <ws>/final.md, extract 3–5 definition-worthy terms, ask which one to render
  • .md file → same as workspace mode
  • empty → ask for a concept or source file

Definition recipe

For the chosen concept, derive:

  1. Genus and differentia — what kind of thing it is, and what distinguishes it
  2. Plain gloss — what it means in ordinary language
  3. Formal signature — a minimal structured definition
  4. Essential distinction — what nearby concepts it must not be confused with
  5. Temporal context — dynasty, institution, or discourse that grounds it
  6. Philosophical core — why the concept matters beyond the glossary level

Rendering contract

Render in ATTRIBUTION-style achromatic discipline:

  • one concept = one signal
  • no chromatic colour
  • title-led composition, quiet grid, wide margin
  • body text should remain spare and legible

Output path:

  • workspace mode → <workspace>/analysis/prometheus/{concept}.svg
  • single-file mode → analysis/prometheus/{concept}.svg
  • pure concept mode → ask for a target directory if none is obvious

If the file exists, ask before overwriting.

Guardrails

  • Do not steal five flames at once: render one concept per invocation.
  • Do not turn the card into a miniature essay.
  • The card should clarify, not merely decorate.
Changes

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.

prometheus is a skill published in the GitHub repository MidnightDarling/collate (6 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 37 tokens to every session and 497 once invoked, about $0.0002 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.
