Crate nexcore_registry 

nexcore-registry — SQLite registry for Claude Code skills, agents, metrics, and KPIs.

Decomposes the monolithic plugins.db into component-specific databases. This crate manages skills.db: the live registry of skills, agents, invocation metrics, SMART goals, KPIs, and audit trail.

Architecture

nexcore-mcp (MCP tool exposure)
    |
nexcore-registry (persistence + scanning + KPI computation)
    |
rusqlite + SQLite (bundled)

Usage

use nexcore_registry::pool::RegistryPool;
use nexcore_registry::skills;

let pool = RegistryPool::open_default().expect("open db");
pool.with_conn(|conn| {
    let all = skills::list_all(conn)?;
    println!("Found {} skills", all.len());
    Ok(())
}).expect("query");
