2analysis-modeling

2analysis-modeling is a skill for Claude Code from jihe520/MathModelAgent. It costs 67 tokens per session (1,135 once invoked), scanned A, original, no licence file.

A mathematical-modeling analysis stage for reading a competition problem and its attachments, breaking it into smaller questions, and designing the models, formulas, objectives, constraints, and solution approach.

In plain words
What is it for?
It is for defining variables, checking assumptions, writing model equations, and preparing a plan that another agent or developer can implement in code.
Why use it?
It turns a broad modeling problem into a structured report that can guide later coding. It also helps check the data and assumptions before implementation begins.

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

2analysis-modeling 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.

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.
