# Deterministic

> Physics-based validation of simulation results. Submit evidence, receive a receipt with
> per-check verdicts, rationale, and provenance; never a model-generated opinion.
> Surfaces: HTTP API, MCP server, CLI, agent skills.

On the deployed site, every HTML page on this origin returns Markdown for `Accept: text/markdown`.
The docs site is indexed separately at /docs/llms.txt (most specific file wins).

## Start here

- [Agent onboarding](https://deterministic.sh/llms-onboard.txt): install → auth → first validation, self-contained
- [Human onboarding](https://deterministic.sh/start): same flow, HTML (Markdown for `Accept: text/markdown`)

## Docs

- [Docs index](https://deterministic.sh/docs/llms.txt): every documentation page, llms.txt format
- [Docs, full text](https://deterministic.sh/docs/llms-full.txt): all pages concatenated, `<!-- url: -->` markers
- [AI agent integration](https://deterministic.sh/docs/ai-agents/): discovery, auth, validate, errors, reports
