What is torchcell CLAUDE.md?

A set of Claude Code instructions for the Mjvolk3/torchcell project. It covers the project's virtual-cell vision, local configuration, Git worktrees, programming practices, and rules for provenance and reproducibility.

Use it when working on torchcell with Claude Code, especially for configuration, worktrees, programming decisions, and reproducible research practices.

It gives coding-agent work the project's intended direction and local working conventions. It also helps preserve traceable, repeatable research and software results.

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.

Model	Per session	Once invoked
Fable 5.1	$0.15565	$0.15565
Opus 5.5	$0.06226	$0.06226
Sonnet 5.5	$0.03113	$0.03113
Haiku 4.5	$0.01557	$0.01557

Security

Grade A, and why

torchcell CLAUDE.md 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 21d 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.

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.
