What v1 will ship with.

First release lands Q3 2026 on Gumroad. Three rules-packs and a five-skill Claude bundle, sized for working developers — not demo-fodder.

  • PACK A · ONE-TIME

    SEC-EDGAR API Consumer Pack

    Cursor rules and prompt templates for developers building portfolio dashboards, screeners, or alerters against Filingrail or any SEC EDGAR API. Working starters planned in Python, JavaScript, and C#.

    PLANNED · $19 ON RELEASE

  • PACK B · ONE-TIME

    .NET + Blazor Production Pack

    Conventions for .NET 8/9 and Blazor Server teams — async-all-the-way, IDbContextFactory, the Result pattern, structured logging, deployment templates. Includes a runnable sample solution with passing tests.

    PLANNED · $19 ON RELEASE

  • PACK C · ONE-TIME

    FastAPI + OpenAPI Conventions Pack

    Schema-first FastAPI patterns that produce marketplace-ready OpenAPI specs from day one. Cursor rules, ten prompt templates, runnable sample service.

    PLANNED · $9 ON RELEASE

A sketch of what a pack ships as — file shapes only, not a working sample.

SKETCH · PACK-C-FASTAPI-OPENAPI NOT A DELIVERABLE
# packs/C-fastapi-openapi/.cursor/rules/

01-schema-first.mdc          # write schemas before handlers
02-no-implicit-returns.mdc   # explicit response_model on every route
03-openapi-tags.mdc          # tagging convention for marketplace listing
04-error-shape.mdc           # standard error envelope
...

# Each rule is a few hundred words + 2-3 worked examples,
# pinned to a specific FastAPI version.

Sketch only. Final layout, file names, and rule counts will land at release.

Part of the Hudson Enterprises portfolio.

Hudson Enterprises ships small, sharp software. Filingrail (the SEC filings API) is live on RapidAPI. RDPMaster (a multi-session remote-desktop app) is in beta. Promptforge and a handful of others are still in build.
