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 | $0.00003 | $0.00343 |
| Opus 5 | $0.00002 | $0.00171 |
| Sonnet 5 | $0.00001 | $0.00069 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
Kotlin Patterns 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.
What it actually says
Kotlin Patterns
When to use this skill
Use this skill when working on Kotlin JVM projects and you want consistent patterns for null-safety, coroutines, and clean module boundaries.
Core patterns
Null-safety as a design tool
Prefer:
- non-null types by default
- validating external inputs early
- avoiding
!!(it’s a runtime crash)
Coroutines (when used)
Rules:
- structured concurrency
- cancellation-aware design
- avoid blocking calls in coroutine contexts
Gradle structure
- keep build scripts readable
- avoid copy-pasting plugin config across modules; share via convention plugins if needed
Testing
- unit tests for pure logic
- integration tests for wiring and persistence
Atlarix tool notes
- Explore: detect Gradle Kotlin DSL (
build.gradle.kts) and locate entry points. - Build: run
./gradlew test/./gradlew build. - Debug: follow stack traces; confirm coroutine context + dispatcher usage.
- Review: check null-safety and coroutine cancellation.
Common mistakes to avoid
- Using
!!to “fix” nullability - Blocking in coroutines
- God modules with unclear dependencies
Mini-checklist
- Nullability is intentional
- Coroutines are structured
- Tests cover critical paths
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.

Kotlin Patterns is a skill published in the GitHub repository AmariahAK/atlarix-skills (2 stars, last pushed 6d ago), licensed Apache-2.0. It adds 3 tokens to every session and 343 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.
