Every layer below is a real product. Two ship as open installs today. Three run inside enterprise engagements. The stack composes — you can run one layer, three, or all five.
The control plane every multi-agent system eventually needs. Persistent memory, token-aware planning, repo-aware file selection, and review gates — wired into one orchestrator that Codex, Claude, Cursor, and your own agents can call.

install · Nexus Prime
$ npm i -g nexus-prime
npm latest · nexus-prime@7.9.27
Coordinate agent memory, context, and execution across handoffs inside a production workflow.
Real compression for real agents. Tetris collapses prose, code, and traces with a multi-channel pipeline so long coding-agent sessions don't blow the context window — and don't blow the bill.

drop-in for Claude, Codex, Cursor
install · tetris.codes
$ curl -fsSL https://get.tetris.codes | sh
one-line installer · live
Compress long coding-agent sessions before context windows become the bottleneck.
Production agents need to read the business — its processes, its artifacts, its rules — without bespoke glue for every integration. Grain is the protocol layer that makes workflows agent-readable so handoffs stop leaking.
Agent-readable workflow schemas
typed handoffs
audit-grade artifact trails
Define a clean protocol boundary so agents can read your workflows the way an engineer can read your codebase.
Naive agent loops burn tokens and stall on cold paths. NXL is the runtime — speculative execution, cache-warm planning, deterministic replay — that turns agent loops into a unit-economical execution layer.
Speculative execution
cache-warm planning
deterministic replay
token unit-economics
Drop the runtime into a hot agent loop and measure cost-per-task before and after.
Real agent work spans hours, days, weeks. Without a mission layer agents drift, work loses intent, and review becomes impossible. Phantom shapes long-horizon work into mission packets your organization can route, remember, and review.
Mission packets
route + remember + review
long-horizon traceability
Shape one long-horizon workflow into a mission packet and ship it as a reviewable operating unit.
