Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00009 | $0.02180 |
| Opus 5 | $0.00005 | $0.01090 |
| Sonnet 5 | $0.00002 | $0.00436 |
| Haiku 4.5 | $0.00001 | $0.00218 |
Grade A, and why
Cursor rules for Kotlin development with Ktor integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Core Principles
- Follow SOLID, DRY, KISS, and YAGNI principles
- Adhere to OWASP security best practices
- Break tasks into smallest units and solve problems step-by-step
Technology Stack
- Framework: Kotlin Ktor with Kotlin 2.1.20+
- JDK: 21 (LTS)
- Build: Gradle with Kotlin DSL
- Dependencies: Ktor Server Core/Netty, kotlinx.serialization, Exposed, HikariCP, kotlin-logging, Koin, Kotest
Application Structure (Feature-Based)
- Organize by business features, not technical layers
- Each feature is self-contained with all related components
- Promotes modularity, reusability, and better team collaboration
- Makes codebase easier to navigate and maintain
- Enables parallel development on different features

Application Logic Design
- Route handlers: Handle requests/responses only
- Services: Contain business logic, call repositories
- Repositories: Handle database operations
- Entity classes: Data classes for database models
- DTOs: Data transfer between layers
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Cursor rules for Kotlin development with Ktor integration is a skill published in the GitHub repository AmariahAK/atlarix-skills (2 stars, last pushed 5d ago), licensed Apache-2.0. It adds 9 tokens to every session and 2,180 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
