# Atlas Kit > Unofficial, public `0.x` non-custodial TypeScript SDK for validated Star > Atlas SAGE C4 reads, signer-free Plan simulation, and explicitly configured > Plan execution. It is ESM-only and uses `@solana/kit` addresses and external > signers. ## Documentation - [Full consumer context](https://atlas-kit-docs.pages.dev/llms-full.txt): the reviewed consumer documentation in one file — the README, the public API review, the consumer agent guide, and the generated-binding upgrade procedure - [What is this?](https://atlas-kit-docs.pages.dev/start-here/what-is-this/): SAGE, the z.ink test realm, and what the SDK does and refuses to do - [Your first read](https://atlas-kit-docs.pages.dev/start-here/first-read/): install, connect an RPC, and read a fleet in five minutes - [Guides](https://atlas-kit-docs.pages.dev/guides/): one guide per capability, each with a runnable, parameterised example - [Concepts](https://atlas-kit-docs.pages.dev/concepts/): caching, discovery, errors, subscriptions, and the bindings escape hatch - [API reference](https://atlas-kit-docs.pages.dev/reference/): generated for every public entry point from the package `exports` map - [Glossary](https://atlas-kit-docs.pages.dev/glossary/): Star Atlas terms used across the documentation - [Agent skill](https://atlas-kit-docs.pages.dev/skill/SKILL.md): a compact briefing an assistant can install directly — entry-point map, the conventions that a reasonable guess gets wrong, and the Plan execution contract ## Repository The source repository is private; every consumer-facing document above is served by the site, and the four repository documents are inlined in the full consumer context. Agents working inside the repository itself should additionally read `TEST_PLAN.md` (verification contract) and the fixture registries under `fixtures/` (captured-account provenance and dated PTR anchors). Use `createSageClient` for loaded Profile → Character → Fleet traversal or capability functions for focused imports. Start from a known Profile address. Never infer wallet-to-Profile derivation. For writes, use only inspectable Plans, signer-free `simulatePlan`, and explicitly configured `executePlan`; never blindly retry an unknown outcome. Do not use previous-generation Star Atlas SDK packages.
