Nisc

An AI-native application platform.

Software, if you let machines write it, shouldn't be code.

Nisc is a monorepo of small, opinionated libraries built around a single thesis: the next generation of software will be authored by language models, audited by humans, and executed by runtimes that refuse to run anything that isn't a validated tree of data.

Not "AI tools." Not "copilots." A stack where every layer — UI, data transforms, LLM calls, orchestration, queries — is a declarative JSON artifact a model can emit, a schema can validate, a runtime can walk, a cache can fingerprint, and a human can diff.

No eval. No generated TypeScript. No SQL string concatenation. No prompt-injected shell-outs. The machines stop typing code and start emitting structure.

If that sounds austere: good.

Packages

Six libraries. Each one is self-sufficient. They also compose.

	Package	Description	Status
📡	@niscorp/signal	Universal LLM client — stateless, immutable, provider-agnostic. Structured output via Zod, tool calling, validation-retry.
🧊	@niscorp/solid	Structured output streaming — incremental JSON parser with structural sharing. Always-valid, schema-backed object stream over partial JSON.
💎	@niscorp/prism	JSON data-transformation DSL — ~50 ops, compile-time optimization, fingerprint-keyed cache, zero code execution.
🎨	@niscorp/nova	Declarative UI runtime — JSON layouts, actions, lifecycles, two-way bindings. Framework-agnostic core, React adapter shipped.
🧠	@niscorp/cortex	Agentic orchestration runtime — typed agents, tool-call loop, plan-mode tick loop, declarative rules engine, human-in-the-loop confirmation.
🔍	@niscorp/vex	Declarative query synthesis — English → constrained JSON DSL → SQL, with scope policies and shape-based caching.

Each package ships its own README.md and DESIGN.md. Read the design doc before reading the source.

Philosophy

Five rules every package obeys, without exception. They're load-bearing.

1 · JSON is the shape

Layouts, transforms, queries, plans — all plain JSON. Serializable, diffable, cacheable, persistable, LLM-emittable. The moment something wants to be a code string, we stop and ask why.

2 · Zod is the truth

Every external input is parsed before it touches a runtime. Provider schemas are compliance hints; Zod is the truth. Errors are structured and, in LLM loops, fed back to the model.

3 · Declarative = observable

If the thing-to-execute is data, the runtime can inspect, log, gate, replay, fuzz, cache, dry-run, and ship it over the wire. Imperative gives you none of that.

4 · Zero-risk execution

LLM-generated artifacts are untrusted by default. No eval, no SQL concat, no tool call without a policy check. If you can inject code into a Nisc runtime, it's a bug — file the report.

5 · No framework lock-in

Nova has a React adapter; its core doesn't import React. Signal has no vendor SDK as a hard dep. Prism is a pure function. Use any one piece standalone — they don't phone home.

Why JSON. Why now.

LLMs are structurally bad at unbounded code and structurally excellent at constrained grammars. Give them a schema and they behave. SQL solved this in 1974; we're doing it one layer up.

Quick start

git clone https://github.com/moccadroid/niscorp.git
cd niscorp
pnpm install
pnpm build

Requires Node ≥ 18.18 and pnpm. Install pnpm with brew install pnpm or corepack enable.

Showroom

A live demo + inspector for the shipping packages. Stories render side-by-side with their JSON definitions, runtime data, and error states.

pnpm --filter showroom dev

→ http://localhost:5173

If the showroom complains about missing dist/, warm the caches once: pnpm --filter showroom... build.

Development

pnpm build         # turbo build
pnpm test          # turbo test
pnpm typecheck     # tsc --noEmit across the workspace
pnpm lint          # turbo lint
pnpm format        # prettier write

Working on one package? Filter it:

pnpm --filter @niscorp/nova test
pnpm --filter @niscorp/nova dev      # tsup --watch

Status

Nisc is pre-1.0 and under active design.

• Shipping packages (Signal, Solid, Prism, Nova, Cortex) are tested and usable, but their public APIs are not frozen. Pin exact versions; expect to update.
• Design-only packages (Vex) have thorough DESIGN.md documents and stub source files. Read the architecture; don't expect runnable code yet.
• Breaking changes land without ceremony until each package hits 1.0.

Contributing

Issues and PRs welcome. Read the relevant package's DESIGN.md before proposing anything bigger than a bug fix — the architecture has opinions, and the opinions are the product.

If a change makes the runtime less observable, less validated, or less declarative, it's probably going the wrong way.
