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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.02994 |
| Opus 5.5 | $0.00007 | $0.01198 |
| Sonnet 5.5 | $0.00004 | $0.00599 |
| Haiku 4.5 | $0.00002 | $0.00299 |
Grade A, and why
mathpix-ocr 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 — 361 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mathpix-ocr - Balanced Ternary OCR Pipeline for LaTeX → ACSet Extraction
Overview
Integrates TeglonLabs/mathpix-gem for mathematical OCR with the music-topos ACSet parallel rewriting system. Uses seed 1069 balanced ternary checkpoints for resilient PDF batch processing.
The 1069 Connection
mathpix-gem shares our canonical seed:
# From mathpix-gem/lib/mathpix/balanced_ternary.rb
# 1×3⁶ - 1×3⁵ - 1×3⁴ + 1×3³ + 1×3² + 1×3¹ + 1×3⁰ = 1069
SEED_1069_PATTERN = [+1, -1, -1, +1, +1, +1, +1].freeze
# Semantics progression:
# +1 (high confidence) → -1 (descent) → -1 (exploration) →
# +1 (recovery) → +1 (convergence) → +1 (stability) → +1 (completion)
This maps directly to our TAP states and GF(3) arithmetic.

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.
- 1mo ago First seen · 361 lines · 18 tokens per session scan A 2df442c70e81
mathpix-ocr is a skill published in the GitHub repository plurigrid/asi (70 stars, last pushed 3mo ago), licensed MIT. It adds 18 tokens to every session and 2,994 once invoked, about $0.0001 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 2026-09-03.
