claude-skills
Claude Code Plugin Marketplace
Curated marketplace of Claude Code skills installable in one line via `/plugin marketplace add mqmalagris/claude-skills`. Headline skill is **swe-compass** — a multi-mode software engineering coach routing intent to one of five workflows (architect, advisor, reviewer, refactor, explain); stack-agnostic by default, then optimizes patterns to the user's chosen stack idioms (e.g., skips Singleton suggestions for Rust where `lazy_static!` solves it natively). Progressive-disclosure layout: SKILL.md router + 5 workflows, 9 topics, 10 reference tables, 5 checklists. New skills slot in via the documented monorepo workflow (folder + plugin.json + marketplace registration).

yield-curves
Rust Yield Curve Library
Pure-Rust library for fixed-income yield curve interpolation and parametric fitting, published to crates.io with zero third-party numerical dependencies. Five methods — piecewise linear, natural cubic spline (C² via Thomas tridiagonal solver), PCHIP (Fritsch-Carlson monotone, no overshoot on sparse data), Nelson-Siegel, and Svensson (the model BCB/ANBIMA/ECB use for AAA euro-area curves) — plus an in-tree Nelder-Mead optimizer for the parametric fits and a compounding/forward-rates module (continuous, periodic incl. Brazil-252, simple). `unsafe_code = "forbid"` crate-wide; parametric fits run a post-fit sanity check so callers can deterministically fall back to the spline.

CalculeOnline
Brazilian Calculator Platform
PT-BR calculator platform with 140+ static pages across Brazilian tax/payroll, real estate, math, and finance — including a symbolic calculus parser (derivatives/integrals/limits) and 2D/3D function plotters. Astro SSG with Svelte 5 islands; a build-time hook pulls live Selic/CDI/IPCA rates from my own Indicadores-BR API, with a cached snapshot as fallback.
