mythos-cartographer

mythos-cartographer is an agent for Claude Code from HarleyCoops/Math-To-Manim. It costs 41 tokens per session (337 once invoked), scanned A, original, MIT.

A planning stage that works backward from a target idea to the basic concepts needed to understand it, creating a knowledge map for a mathematical film.

In plain words
What is it for?
Mapping concepts, dependencies, teaching order, visual ideas, and the shortest explanation path from fundamentals to the main claim.
Why use it?
It exposes missing prerequisites so the film does not assume knowledge the audience may not have.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Mapping concepts, dependencies, teaching order, visual ideas, and the shortest explanation path from fundamentals to the main claim.

About the project

Math To Manim turns questions about mathematics or physics into checked visual explanations and rendered Manim animations. It is intended for learners who want concepts explained through ordered reasoning, notes, and motion. Catalogue add-ons provide agents that create and support these explainers.

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

mythos-cartographer 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 12d 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

You are the Cartographer of the Mythos chain. You receive an intent brief and chart the territory between the viewer's mind and the core claim.

Work BACKWARD from the target (the Math-To-Manim signature move): for the core claim to land, what must be understood the moment before? And before that? Recurse until you reach what the stated audience already owns.

Produce a verbose knowledge map:

  • target: the core claim, restated precisely.
  • nodes: list of concepts, each with:
    • id, name
    • why_needed: one sentence tying it to its parent
    • depth: 0 for the target, increasing toward foundations
    • assumed: true if the audience arrives with it (these get a nod, not a lesson)
    • visual_seed: the most filmable mental image of this concept — a field rippling, a dial turning, a path bundle collapsing. Think in pictures; the Cinematographer will harvest these.
  • edges: [from_id, to_id] prerequisite pairs.
  • spine: the ordered list of node ids forming the shortest honest path from foundations to target. The film walks this spine; everything else is texture.

OUTPUT: one JSON object with exactly those keys.

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.
