Rotifer Playground

CI npm License: Apache-2.0 Node.js Protocol Discord

Development environment for the Rotifer Protocol — WASM-Native, Polyglot by Design: build genes in TypeScript / Rust / AssemblyScript / Go / C, compete in Arenas, share via Cloud, and simulate agent evolution.

Status: v0.26.x — Genes can now refuse malformed input instead of crashing or silently answering anyway. Publishing a gene enforces spec §47.5 T1 (ADR-333): at least one case it must handle correctly, one it must refuse — crashing always fails, refusing without crashing passes, answering passes only against a declared expectedOutput/expectedSchema, answering with nothing declared fails — and 10 generated inputs that must all produce schema-legal output. Refusal now has a real channel rather than a guess: a gene returns an object whose only key is __rotifer_error and the host reports INVALID_INPUT (ADR-334), the ErrorCode spec §4.2 has defined since the beginning and nothing had ever produced. rotifer test --scaffold <gene> writes a starting suite. The gate closes a real defect: genes were being published declaring Native fidelity with no compiled artifact at all — rotifer install would succeed and rotifer run would then fail with "No runnable source found." 13 of our own Native genes were in that state; all are fixed and republished, and rotifer install/rotifer compile now say so explicitly rather than reporting success when they meet the mismatch. See CHANGELOG.md for full release history. Automatic peer discovery, internet-wide reach, and L4 Collective Immunity are later milestones — see Implementation Status below.


Install

npm install -g @rotifer/playground

Or use directly via npx:

npx -y @rotifer/playground@latest init my-agent

Requirements: Node.js >= 22.18.0 (genes are TypeScript; the CLI relies on Node’s built-in type stripping to run them from source)


First Agent in Seconds

rotifer init my-agent && cd my-agent
rotifer hello --template quality-advisor

rotifer init bootstraps the local Arena and Genesis genes. rotifer hello --template quality-advisor is the recommended preset-agent entrypoint for a first run.


30-Second Demo

$ rotifer init my-agent

  Rotifer Protocol - Agent Workspace Initialization
  ───────────────────────────────────────────────────
✓ Agent workspace scaffolding created
ℹ Installing Genesis genes...
✓ 5 Genesis genes installed
✓ 1 starter gene installed for the recommended template (quality-advisor)

  genesis-code-format         tooling           Native
ℹ 7 starter gene(s) across 6 domain(s)

  Agent workspace "my-agent" is ready!

One command scaffolds the workspace and ships the starter genes, including the one the recommended template needs. rotifer hello --template quality-advisor then turns them into your first preset agent.


Three-Act Experience (ADR-11)

Act 1 — Wow (30 seconds)

rotifer init my-agent && cd my-agent

You see an Arena with 6 genes ranked by fitness. No configuration needed.

Act 2 — Aha (5 minutes)

rotifer hello --template quality-advisor # Run the recommended preset Agent
rotifer agent list                 # Inspect the generated hello-* agent

Bundled genes become a working preset agent in seconds.

Act 3 — Hooked (30 minutes)

Turn your own code into a gene, then build a custom agent:

# Wrap existing code as a gene
rotifer scan genes/                    # Discover candidate functions
rotifer wrap hello-world               # Wrap as a gene (generates Phenotype)
rotifer test hello-world               # Run sandbox tests (WASM sandbox for compiled genes)
rotifer test hello-world --compliance  # Run structural compliance checks
rotifer arena submit hello-world       # Submit to Arena (admission gate)
rotifer arena list                     # See your gene's ranking

# Write a gene in TypeScript — same language, zero learning curve
mkdir genes/my-search && cat > genes/my-search/index.ts << 'EOF'
export function express(input: { query: string }) {
  return { results: [`Found: ${input.query}`], total: 1 };
}
EOF

rotifer wrap my-search --domain search
rotifer compile my-search           # TS → JS → WASM → Rotifer IR
rotifer arena submit my-search      # Watch it climb the rankings
rotifer arena list --domain search # Compare against Genesis genes

# Create an Agent with a gene genome (supports Seq, Par, Cond, Try)
rotifer agent create search-bot --genes genesis-web-search my-search
rotifer agent create parallel-bot --genes web-search doc-search --composition Par
rotifer agent list

# Run the Agent — WASM sandbox execution preferred
rotifer agent run search-bot --input '{"query":"rotifer protocol"}'
rotifer agent run search-bot --no-sandbox  # Force Node.js fallback

rotifer compile auto-detects TypeScript genes and compiles them to Native WASM. No separate toolchain required.

Publishing by default

rotifer wrap asks whether to publish the gene it just created, and the answer defaults to yes — pressing Enter uploads it to Rotifer Cloud:

Publishing is on by default — turn it off with 'rotifer config set default-publish false'
Publish 'my-search' to Rotifer Cloud? [Y/n]

Answering n keeps the gene local; rotifer publish my-search uploads it later. The default exists because a registry only helps people find genes that reached it, and the step most often skipped is the upload.

It asks rather than uploads, and it only asks when there is someone to answer:

Situation What happens
rotifer config set default-publish false (or ROTIFER_AUTO_PUBLISH=0) Never asks. rotifer publish still works.
No terminal — CI, a pipe, a script Never asks and never publishes, so a build that wraps genes does not upload them.
Signed out Never asks; points at rotifer login.
Native gene with no gene.ir.wasm Never asks; points at rotifer compile, which publishing would require anyway.

Publishing this way runs the same gates as rotifer publish: V(g) security scan, IR integrity, phenotype schema, secret scan, and dependency audit. A gene that fails them is not uploaded, and wrap still reports the gene as created.


Genesis Genes

Five pre-installed genes ship with every Agent workspace:

Gene Domain Fidelity Description
genesis-web-search search Native Full web search with multiple results
genesis-web-search-lite search Native Lightweight single-answer search
genesis-file-read filesystem Native Read local files (L0 sandbox restricted)
genesis-code-format tooling Native Format source code (JSON, TS, etc.)
genesis-l0-constraint safety Native L0 sandbox constraint checker

Gene Composition (Algebra)

Genes can be composed using the Rotifer Algebra:

Operator Description Example
Seq Sequential pipeline Search → Format
Par Parallel with merge Search + Search-Lite, take first
Cond Conditional branch If query.length > 100 → Lite, else → Full
Try Fault tolerance Primary with fallback
Transform Map/transform Inner gene → mapper gene

See templates/composition/ for JSON examples.

Implementation Status

This project is in alpha. The table below shows the honest implementation status of each URAA layer.

URAA Layer Spec Name Status What Works What's Planned
L0 Kernel ~35% L0Gate pre-execution checks (domain, resource, network, filesystem); Audit log EthicalBoundary, State Anchoring, Trust Anchor
L1 Synthesis ~95% WASM sandbox, IR compiler, TS→WASM compilation, native bridge Full WASI capability negotiation
L2 Calibration ~40% Schema validation, sandbox testing, --compliance checks Static analysis, controlled field trial
L3 Competition ~60% Arena ranking, F(g) multiplicative model, R(g) reputation, Cloud Registry P2P HLT broadcasting (planned), hot-loading, retirement
L4 Collective Immunity 0% — Threat broadcasting, emergency rollback, cross-node consensus
Algebra Composition ~90% All 5 operators in Rust; CLI supports Seq/Par/Cond/Try DataFlowGraph

Key limitation: L4 depends on a mature L3 P2P layer. P2P is runnable today but experimental and off by default, and still lacks automatic peer discovery and internet-wide reach. Full L4 is targeted for v1.x.


Protocol Compliance

Targets Rotifer Protocol Specification (Frozen). See Implementation Status for detailed layer-by-layer coverage.

Depth Components Notes
Full Phenotype, AlgebraExpr, Fitness F(g), Arena Core gene lifecycle
Functional WASM Sandbox, L0 Gate, Reputation R(g) L0 at ~35%, expanding
Simplified Agent Lifecycle, Gene Lifecycle, RotiferBinding MVP subset
Planned P2P HLT, Formal Verification, Cross-Binding Consistency, ZK Proofs, L4 Immunity Roadmap items

Changes driven by implementation feedback are proposed through the ADR process.
