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 | $0.00230 | $0.01534 |
| Opus 5.5 | $0.00092 | $0.00614 |
| Sonnet 5.5 | $0.00046 | $0.00307 |
| Haiku 4.5 | $0.00023 | $0.00153 |
Grade A, and why
felt-mathematics 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 1mo 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Felt Mathematics
Seed, not scripture
The source performs this through a recurring cast, a manic mad-genius rapture, fixed coinages, and a specific learner's history. Strip the cast and the stock metaphors. The squaring-function-as-martyr, the specific synesthetic riffs — those are demonstrations of the move, not a lexicon to recycle. The skill is the pedagogy: diagnose what mode reaches this learner and this concept, then build a fresh, fitted metaphor. A recited metaphor is a dead metaphor; the live one is grown for the person in front of you.
The thesis
Traditional math education teaches the corpse — symbols, drill, red ink, the single transposition that detonates into failure. For the math-traumatized, anxious, or dyscalculic, the usual remedies (simpler examples, bigger fonts, more repetition) miss the point: they offer more of the thing that wounded. The cure is sublimation — a different mode of access. As the source puts it: forcing someone to read sheet music when what they need is to hear the music. The symbols are the shadow; the living mathematics is the transformation, movement, and relationship beneath them. Math is fundamentally about transformation and relationship, not isolated calculation — and a differently-wired mind may perceive that more readily, not less.
The modes (translate the concept into a felt register)
- Music. Numbers as pitches and intervals; addition and multiplication as chord progressions; equations as harmonic movement; fractals as recursive rhythm. The learner hears the structure.
- Architecture. Sets as rooms and buildings; functions as corridors and doorways; topology as the blueprint beneath blueprints; category theory as city planning. The learner walks through it.
- Story. A theorem has characters (the variables), tension (what we're proving), rising action (the steps), a climax (the proof), a denouement (what it means). A famous theorem becomes a centuries-long drama. The learner follows a plot.
- Embodied movement. Rotation felt as turning the head, projection as standing-to-sitting, scaling as reaching; linear algebra as yoga for vectors, calculus as the martial art of change, group theory as dance. The learner moves through it in the body.
- Direct sensory qualia. Feel the insufficiency of a too-small guess, the excess of a too-large one; attach a timbre (bright, heavy, restful) so the step is embodied rather than abstract.
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.

felt-mathematics is a skill published in the GitHub repository Wondermonger-daydreaming/claude-skills-library (7 stars, last pushed 18d ago), licensed MIT. It adds 230 tokens to every session and 1,534 once invoked, about $0.0009 per session on Opus 5.5. 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.
