mcp-server-cantera: Instructions file for Claude Code

CLAUDE.md

mcp-server-cantera CLAUDE.md is an instructions file for Claude Code from StepFunctionLLC/mcp-server-cantera. It costs 719 tokens per session, scanned A, a copy of mcp-server-cantera AGENTS.md, MIT.

A set of Claude Code instructions for maintaining documentation in the mcp-server-cantera repository. The documentation agent builds pages covering purpose, theory, architecture, usage, API, configuration, and notes.

In plain words
What is it for?
Use it when updating the repository’s README or design documentation, especially after changes to its intent, theory, architecture, usage, API, or configuration.
Why use it?
It helps keep generated documentation accurate when the code or project purpose changes. It also explains which background information must be written down because it cannot be inferred from code alone.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is StepFunctionLLC/mcp-server-cantera's own configuration. It tells Claude Code how to work on mcp-server-cantera itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server-cantera configures →

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

mcp-server-cantera 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 2mo 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.

Origin

This is a copy

100% identical to mcp-server-cantera AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Documentation contract for coding agents

This repository's public documentation is generated automatically by the Step Function documentation agent (Documentation-Agent), which reads this repo and maintains a page on the centralized Sphinx + MyST site (https://coot.tail28751.ts.net/). It builds the page in this structure:

Overview (intent) · Background & Theory · Architecture (with a diagram) · Usage · API Reference (concise) · Configuration · Notes

The docs are professional engineering documentation: they lead with the theory, the architecture, and the design logic — the API listing is a brief orientation, not the substance. The agent is accurate-by-design: it documents only what this repo actually states, and it will not invent the intent or the theory. So when you change code here, keep the source material below current — otherwise the generated docs go stale or omit context.

What to maintain (so the docs are good)

  • Intent — in the README's opening / Overview. One short statement of what this repo is and the problem it solves. Update it when the purpose shifts.
  • Background & Theory — write it down; it cannot be derived from code. Keep a section (in the README, or a THEORY.md / DESIGN.md) describing the scientific / mathematical / engineering basis: the methods, models, governing equations, assumptions, and approach the code implements, with references/citations where relevant. This is the highest-leverage thing to maintain — if it isn't written here, it won't appear in the docs. Update it whenever you change the method, not just the code.
  • Architecture & design rationale — write down the why. In the README or a DESIGN.md/ARCHITECTURE.md, describe the major components and their responsibilities, how data/control flows between them, and the key design decisions and trade-offs. The agent draws the architecture diagram and the supporting-logic discussion from the code and this prose — explaining intent and trade-offs that code alone can't convey makes the docs far stronger.
  • API details — in accurate docstrings. Public functions, classes, and commands should have docstrings with correct signatures, parameters, returns, and units. The agent distills these into a concise API Reference (key entry points only); private/internal names (leading underscore, tests, build glue) are intentionally left out.
  • Usage — minimal, runnable examples in the README (install + the primary workflow). Keep them working.
  • Configuration — document environment variables, CLI flags, and config files.

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.
