Native SDK is a toolkit for building desktop applications with native rendering instead of a browser, WebView, or JavaScript runtime bundled into the application. Developers author interfaces in `.native` markup and write application logic in TypeScript or Zig, which the toolkit compiles and renders in real operating-system windows. The catalogue entries provide skills and instructions for working with Native SDK.

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 | $0.00851 | $0.00851 |
| Opus 5.5 | $0.00340 | $0.00340 |
| Sonnet 5.5 | $0.00170 | $0.00170 |
| Haiku 4.5 | $0.00085 | $0.00085 |
Grade A, and why
native AGENTS.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 1mo 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.

App authoring default
Native SDK itself is implemented in Zig, but Native SDK apps are authored in TypeScript + Native markup by default. Do not infer the app-authoring language from this repository's implementation language or from older Zig-core examples.
- For a new app, use
native init <path>and expectsrc/core.ts,src/app.native, andapp.json.app.zonremains a supported legacy/alternative manifest. Ordinary compiled TypeScript work that needs filesystem, process, JSON, regex, classes, or other static-tier APIs belongs under optionalsrc/services/, reached from the core withCmd.request; do not import a service from the core. Do not add Zig app code unless the user explicitly chooses--template zig-coreor the feature requires a toolkit extension. - Before changing an existing app, inspect its tree. A
src/core.tsapp stays TypeScript; asrc/main.zigapp stays Zig unless the task is specifically a migration. - For default app work, read
skill-data/native-ui/SKILL.mdandskill-data/ts-core/SKILL.md; also readskill-data/ts-services/SKILL.mdwhen the tree hassrc/services/or the task needs ordinary TypeScript beyond the core subset.skill-data/core/SKILL.mdcovers shared/runtime concerns;skill-data/zig/SKILL.mdis for Zig-core apps and SDK implementation work. - The
-tssuffix on a few examples only distinguishes ports from older Zig originals. New TypeScript apps need no suffix because TypeScript is the default.
Build, test, and gate
zig build test # root engine + runtime suites
zig build validate # framework's legacy app.zon manifest check
zig build test-example-<name> # one example's suite (e.g. test-example-notes)
scripts/gate.sh fast [ref] # affected-only local gate for your diff (default base: main)
scripts/gate.sh full # everything CI-shaped that runs locally
Run scripts/gate.sh fast before finishing any change; it maps your diff to the suites that cover it. The docs site checks with pnpm --dir docs check (the gate runs it only when docs/ changed).
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.

native AGENTS.md is an instructions file published in the GitHub repository vercel-labs/native (7,804 stars, last pushed yesterday), licensed Apache-2.0. It adds 851 tokens to every session, about $0.0034 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
