Nexus-Agents Entrypoints

Last Updated: 2026-06-02 (ET) Canonical Source: This document is the single source of truth for all entrypoints. Issue: #210 (Epic #209)

Overview

Nexus-agents provides four interface categories:

Quick Reference

Most commonly used commands:

CLI Commands

Entry Point: nexus-agents [command] [options]

Commands are grouped by user persona. Daily use is what you’ll type during a normal session; setup & inspection runs at install / config time; debug & observe is for when something looks off; server / internal is called by hooks, CI, and editor MCP clients — not usually directly.

MCP Tools

Protocol: Model Context Protocol (2025-11-25) Transport: JSON-RPC 2.0 over stdio

Auto-generated from REGISTERED_TOOL_NAMES + TOOL_DESCRIPTIONS by scripts/inject-governance.ts. 46 tools.

Rate limiting: All tools share a single token bucket rate limiter (capacity: 100 tokens, refill: 10 tokens/sec). Each tool call consumes one token.

Tool Schemas

Full per-tool input schemas — every parameter with its type, required/optional status, constraints (enum members, min/max, pattern, defaults), and description — live in the generated MCP Tool Reference. Those pages are generated directly from the registered Zod input schemas (pnpm docs:tools) and drift-gated in CI, so they never fall out of sync with the runtime contract.

Agents should discover schemas live via the MCP tools/list request; the generated reference is the human-readable companion.

Built-in Workflow Templates

11 built-in templates are available (source: src/workflows/template-types.ts):
