Open Source Ecosystem

Enterprise production code, now available to the community.

The Nexss Framework originates from a battle-tested commercial enterprise codebase. We are progressively open-sourcing its core execution engines, multi-protocol transports, and AI context compressors.

  • SRCPACK
  • KERNEL
  • TRANSPORT
  • TRANSPORTAI
  • TESTKIT
Deterministic Context Engine

nexssp/srcpack

Source code compressor & context engineering engine built for LLMs, Claude Desktop, Cursor, Windsurf, MCP, and A2A multi-agent DAG pipelines.

  • AST token compression (65%–85% context reduction)
  • Multi-transport: CLI, MCP Server (stdio), REST API & A2A
  • In-memory secret masking & visual ASCII token tree index
  • Multi-language: Go, TypeScript, TSX, Vue, Python, Rust, Zig
Core Execution Engine

nexssp/kernel

Typed action lifecycle with sub-microsecond dispatch (< 50ns/op). Context-based RBAC, idempotency, exponential jitter retries, fenced distributed locks, sagas, and DAG pipelines.

  • Zero reflection & zero allocations on the hot path
  • Context guards (RequireRole, RequireTenant, PIITracker)
  • Fenced monotonic distributed locking (split-brain safe)
  • Deterministic parallel DAG engine (ai/dag) & Sagas
AI Agent Protocols

nexssp/transportai

Turn existing business actions directly into AI Agent tools for Anthropic Claude, Cursor, Windsurf, and multi-agent coordination frameworks.

  • tmcp: Model Context Protocol (MCP) over stdio & SSE
  • ta2a: Agent2Agent protocol with Agent Cards & task states
  • Automated tool schema generation from Go structs
  • Dynamic prompt templates with variable validation
Multi-Protocol Adapters

nexssp/transport

Bind kernel actions simultaneously to HTTP/REST, Server-Sent Events, CLI subcommands, in-process event bus, cron schedules, and priority worker queues.

  • thttp: REST, SSE, streaming NDJSON & tag binding
  • tcli: Flag parsing (cli:"flag,f"), args & auto-generated help
  • cron & tworker: Scheduled jobs & background workers
  • taskqueue: High/Normal/Low priority lanes with DLQ
Testing & Automation

nexssp/testkit

Zero-dependency integration and performance testing suite built for high-throughput systems, bypassing heavy Docker environments.

  • RunSmokeTests: Automated endpoint fuzzing to catch panics
  • Simulate: Concurrency & thundering herd synchronization
  • LoadTest: In-memory RPS, p50/p95/p99 latency benchmarking
  • ListenSSE: Real-time Server-Sent Event stream testing

Architecture Evidence

Ported from Enterprise Production

These packages bring battle-tested patterns—from split-brain-safe distributed coordination to deterministic AST compression—directly to your engineering stack.

go source example
// 1. One-line CLI context generation
// $ srcpack arch --tree -c
// Extracts exported AST signatures, prepends ASCII token tree, masks secrets, copies to clipboard.

// 2. Mount as an MCP Tool for Claude / Cursor / Windsurf
server := tmcp.New("srcpack-mcp", "1.1.0")
server.Mount(actions.AllActions)
_ = server.ServeStdio(ctx)

// 3. Multi-Agent DAG Pipeline (Agent-to-Agent)
client := ta2a.NewClient("http://localhost:8091")
packerAct := client.AsAction("remote.packer", "packer").Build()

pipeline, _ := dag.New("ai_review_dag").
    AddNode("pack_ctx", "context", packerAct).
    AddNode("llm_audit", "audit_report", llmAuditAct).
    AddEdge("pack_ctx", "llm_audit").
    Compile()

All execution pipelines compile into zero-allocation call graphs at Build() time. Context authorization, idempotency, distributed locks, and sagas execute with strict Go idioms.
