main-kts from heapy/kortex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when creating, writing, or running standalone executable Kotlin scripts with the `.main.kts` extension, including the `kotlin` script runner, shebang execution, `@file:DependsOn`/`@file:Repository`/`@file:Import`/`@file:CompilerOptions`/`@file:OptIn` annotations, script dependencies, command-line `args`, compiled-script caching, GitHub Actions setup with Heapy/setup-main-kts, and common scripting libraries such as ktor, kotlinx-serialization, kotlinx-coroutines, clikt, and kotlinx-html.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Kotlin Scripts (.main.kts) Use this skill to generate and run executable Kotlin `.main.kts` scripts: single-file programs that declare their own dependencies, run directly from the shell, and need no build file. This is the `kotlin` script runner, not Kotlin Toolchain, Gradle, or Maven. Do not add `module.yaml`, `build.gradle`, or `pom.xml`. If the task needs a real multi-file project or published artifact, it is not a `.main.kts` task. ## When To Use - A one-off automation, glue, or CLI utility that should run with `./script.main.kts` or `kotlin script.main.kts`. - The user wants Kotlin without project scaffolding or a build system. - Quick API calls, file munging, JSON processing, HTML generation, or shell orchestration. Prefer a real Kotlin Toolchain or Gradle module when the code grows multiple source files, needs incremental builds, or ships as a library or application artifact. ## Gather Requirements Before writing, confirm: 1. What the script should do (purpose and behavior). 2. A name (suggest one from the behavior; the file must end in `.main.kts`). 3. Where to save it (default: current directory). 4. Any inputs it takes (command-line `args`, env vars, stdin). …

How to install
mdr add heapy/kortex/main-kts@sha256:52e9ec601eea24d6The line at the top of this page pins the label git:20261008.8208ee6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
