Aevrix Studio · v1.0 launch

Rules your AI editor will actually obey.

The five packs

Production patterns, packaged.

Each pack ships .mdc rule files for Cursor, a CLAUDE.md for Claude Code, working reference code, and a license that covers solo and team use.

PACK 01

Flutter + Riverpod Mastery

10 RULES · DART · RIVERPOD 2.4+

Catches the recurring AI mistakes in Flutter PRs: leaked Streams, broken AsyncValue, mutable state, missing const, undisciplined navigation, missing accessibility.

AsyncNotifier patterns + AsyncValue.when discipline

freezed + copyWith immutability rule

i18n (AZ/EN/RU), accessibility, performance budgets

$29Personal · $99Commercial

Cursor · Claude · Cline · Continue

PACK 02

FastAPI + SQLModel Production

11 RULES · PYTHON · FASTAPI 0.110+

Eleven rules that catch the production-killers AI agents repeat: untyped Depends(), raw SQL, missing migrations, sync calls in async routes, JWT without refresh, no rate limits.

Annotated[Session, Depends(...)] discipline

SQLModel typed queries + Alembic reversibility

JWT refresh, rate limiting, OpenAPI hygiene

Cursor · Claude · Cline · Continue

PACK 03 · FLAGSHIP

Hermes-Style Agent Loops

12 RULES + REFERENCE OPERATOR

Flagship

Distilled from Hermes — a multi-LLM agent framework running daily at scale. Sentinel discipline, multi-LLM routing, cost ceilings, safe-mode guardrails. Every rule was a 3 AM debugging session.

Sentinel protocol: WATCHDOG_DONE / PAUSE / FAIL

Multi-LLM router + error classifier + budget kill-switch

~300 LOC reference operator demonstrates all 12 rules wired

$49Personal · $199Commercial

Framework-agnostic LLM SDK

PACK 04

Multi-LLM Fallback Patterns

10 RULES + REFERENCE ROUTER

For engineers running more than one provider — Anthropic, OpenAI, Bedrock, Gemini, OpenRouter — who need a router that fails over on the right errors, caches the right responses, and respects a budget.

Provider abstraction + capability map + cost-aware routing

Latency P95 stickiness, retry budgets, never-retry list

~200 LOC reference router with adapters + test suite

$39Personal · $159Commercial

Anthropic · OpenAI · Gemini · OpenRouter

PACK 05

MCP Server Production Patterns

12 RULES + PYTHON & TS REFERENCES

For developers building MCP servers — for Claude Code, Cursor, Cline, or internal tooling — who want tool schemas LLMs invoke correctly, transports that don't drop events, and pricing that survives a marketplace audit.

Tool surface design + LLM-readable documentation

stdio + HTTP + WebSocket with backpressure

Marketplace submission + paid MCP pricing patterns

$39Personal · $159Commercial

Python · TypeScript

BUNDLE

Studio Complete

ALL 5 PACKS · 55 RULES · 4 REFERENCES

All five packs in one purchase. The complete Aevrix Studio rule set for teams that ship Flutter, FastAPI, agent loops, multi-LLM routers, and MCP servers from the same codebase.

How a pack works

Three steps. One reload.

Each pack is a folder of .mdc rule files plus a CLAUDE.md. Drop them into your project, reload your editor, and the next prompt obeys.

STEP 01

Drop the rules in

cp -r pack/.cursor/rules ./.cursor/rules and append CLAUDE.md. That's it. No build step, no config file, no plugin install.

STEP 02

Reload your editor

Cursor reads .cursor/rules/*.mdc automatically based on globs and alwaysApply frontmatter. Claude Code activates via CLAUDE.md. Cline and Continue read both.

STEP 03

Ask for the feature

Type the feature you want. The agent now writes code in the patterns the pack enforces — no manual nudging, no review-comment ping-pong on the same five mistakes.

FAQ

Common questions.

What is a Cursor / Claude Code rule pack?

A folder of .mdc Markdown files with frontmatter (description, globs, alwaysApply) that Cursor and compatible editors load as project-level engineering policy. The agent applies them automatically when the file globs match. Aevrix Studio packs distill production patterns into these files so AI-generated code arrives already conforming.

Will this work with Claude Code as well as Cursor?

Yes. The .cursor/rules/*.mdc format is read by Cursor; the bundled CLAUDE.md activates the same constraints for Claude Code. Cline and Continue read both via standard config. Tested as of May 2026 against Cursor 0.45+, Claude Code 1.x, Cline 3.x, Continue 0.9.x.

What is the difference between Personal and Commercial?

Personal is one named developer with unlimited Personal Projects. Commercial covers an entire legal entity (all paid contributors), permits use inside products you sell to third parties, and permits internal forking. The full LICENSE ships in every pack — read it before purchase.

Do I get updates and what is the refund policy?

Patch-level updates within v1.x are free for the life of your license, delivered through Lemon Squeezy. Major versions may require renewal. Refunds: 14 days, no questions asked. After 14 days we still consider refunds case-by-case — write to licensing@aevrix.group.

Can I redistribute or open-source what I build with these packs?

Yes — the product you build with these patterns is yours. What you cannot do is republish the pack itself (rules, reference code, docs) as your own product or as a public template. See LICENSE Section 4 for the exact line.

Why should I trust packs from a brand new vendor?

The patterns come from production codebases shipping daily — Hermes (multi-LLM agent framework), Axion (E2EE messenger), Karavan (multi-tenant marketplace). Aevrix Group operates from Baku, Azerbaijan, with public Trust Center at aevrix.org, security contact at security@aevrix.org, and corporate site at aevrix.group.
