# SIMT Space > The reference and the tools behind the SIMT products. > SIMT Space publishes the design and engineering reference for the SIMT products, and the tools that read it. Every product is static, canonical and machine-readable. ## The SIMT spaces - Digital Space: [SIMT App](https://simt.app). An offline spatial toolkit for your pocket and your wrist. Plan targets, track where GPS fails, measure in AR and follow the sky, all computed on your device. - Human Space: [SIMT Social](https://www.simt.social). A living map where the people nearby are the map. Discover activities and coordinate local plans, right in your browser. - Physical Space: Coming soon…. Something is condensing out of the dust, in the world you can touch. Its signal is still too faint to name. - Design System: [Cosmos](https://simt.space/cosmos-design). The design language every SIMT product is built on: one specification in five parts, with the tokens, rules and agent brief derived from it. The registry is published in [English](https://simt.space/), [Français](https://simt.space/fr), [العربية](https://simt.space/ar), [Español](https://simt.space/es). ## Products - [Cosmos Design System](https://simt.space/cosmos-design): The design contract for every SIMT product: one specification, five parts, and the machine-readable tokens, rules and agent brief derived from it. ## Cosmos Design System - [Overview](https://simt.space/cosmos-design/): One shared foundation and four platform parts. The four theme profiles are the single definition of a surface; Deep Space is the signature and Daylight, Astronomy red and Watch ambient are real, selectable adapters the documentation itself renders in. - [Common foundations](https://simt.space/cosmos-design/common/): The shared Cosmos contract: palette, type, geometry, components, accessibility, motion, data and production acceptance. - [Web page](https://simt.space/cosmos-design/web-page/): Cosmos public and marketing websites: editorial horizons, a useful atlas, product evidence, conversion, SEO and restrained motion. - [Web app](https://simt.space/cosmos-design/web-app/): Cosmos for Simt Social: continuous map/list discovery, context-preserving detail, activity composition, profiles, inbox and operations. - [Mobile app](https://simt.space/cosmos-design/mobile-app/): Cosmos for SIMT Android: compass, map, sky, tracking and tool layouts, adaptive postures, native input, sensors and measured performance. - [Watch app](https://simt.space/cosmos-design/watch-app/): A simplified Cosmos for SIMT Wear OS: round-screen instruments, accessible rotary input, concise tools and battery-aware ambient states. - [Gallery](https://simt.space/cosmos-design/gallery/): Every component drawn from its own contract: the state matrix in the rule's own wording, the timing from the named motif, and the colours from the published tokens. - [Gallery · Actions and selection](https://simt.space/cosmos-design/gallery/actions/): The actions and selection family, governed by C12 and W03, every component drawn from its registry entry. - [Gallery · Inputs and validation](https://simt.space/cosmos-design/gallery/inputs/): The inputs and validation family, governed by C13, every component drawn from its registry entry. - [Gallery · Records and navigation](https://simt.space/cosmos-design/gallery/records/): The records and navigation family, governed by C14, every component drawn from its registry entry. - [Gallery · Layers and dialogs](https://simt.space/cosmos-design/gallery/layers/): The layers and dialogs family, governed by C15 and C26, every component drawn from its registry entry. - [Gallery · Feedback at the source](https://simt.space/cosmos-design/gallery/feedback/): The feedback at the source family, governed by C16, every component drawn from its registry entry. - [Gallery · Instruments and readings](https://simt.space/cosmos-design/gallery/instruments/): The instruments and readings family, governed by C08 and C18 and M03 and M10, every component drawn from its registry entry. ### Machine-readable resources - [Resource manifest](https://simt.space/cosmos-design/manifest.json): Version, authority, platform inheritance, stable section URLs and download links. Start here for automated implementation. - [Specification index](https://simt.space/cosmos-design/specification.json): The pages, their sections and the rule IDs in each. Read this first, then fetch only what the task needs. - [Normative rules](https://simt.space/cosmos-design/rules.json): Every rule once, grouped by platform section, each with its normative level, requirement, acceptance criterion and canonical URL. - [Typed design tokens](https://simt.space/cosmos-design/tokens.json): Self-contained typed base tokens plus the theme adapters, the per-platform geometry and easing mapping, and the address of the composited contrast measurements. - [Composited contrast](https://simt.space/cosmos-design/contrast-pairs.json): Measured composited contrast for every role pair in every theme profile, with the guidance for each pair. Fetch it when introducing a colour, pairing a translucent surface or checking a theme. - [Motion motifs](https://simt.space/cosmos-design/motion.json): The named choreographies a state change animates with, each with its trigger, steps, allowed properties, duration, easing and per-tier and per-platform behaviour, plus the sampled curve values a native port reproduces. Fetch it when choosing a choreography, deciding between motion tiers or porting a transition to a native toolkit. - [Component index](https://simt.space/cosmos-design/components.json): Rule IDs, theme roles, states, motifs and native counterparts per component, sliced by platform part. - [Web token variables](https://simt.space/cosmos-design/tokens.css): Scoped CSS custom properties, one set per theme profile, plus the brand anchors. - [Agent design skill](https://simt.space/cosmos-design/cosmos-design-skill.md): A short Markdown brief for an agent about to build or review SIMT interface. Quoted from the specification source, so it cannot drift. - [Complete plain-text specification](https://simt.space/cosmos-design/specification.md): The full readable contract in Markdown. - [Release changelog](https://simt.space/cosmos-design/changelog.md): What every published Cosmos version changed, newest first. The current version also states its own changes in specification.md. - [Specification schema](https://simt.space/cosmos-design/specification.schema.json): JSON Schema for the index. - [Rules schema](https://simt.space/cosmos-design/rules.schema.json): JSON Schema for the normative rules document. - [Release record template](https://simt.space/cosmos-design/release-template.json): Product, build, environment, applicable rules, evidence, dependencies and exceptions. ## Agent discovery - [https://simt.space/.well-known/ard.json](https://simt.space/.well-known/ard.json): the Agentic Resource Discovery catalog. `robots.txt` points at it with `Agentmap:`. The same bytes are served at the predecessor path `/.well-known/ai-catalog.json`.
