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.

What it costs to keep this loaded
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 | $0.00046 | $0.00640 |
| Opus 5 | $0.00023 | $0.00320 |
| Sonnet 5 | $0.00009 | $0.00128 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
xmake-kotlin 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building Kotlin (Native) with Xmake
Xmake's Kotlin support targets Kotlin/Native — the ahead-of-time-compiled flavor, not JVM. For JVM-side projects, use Gradle/Maven directly.
1. Minimal project
xmake create -l kotlin -t console hello
cd hello
xmake run
add_rules("mode.debug", "mode.release")
target("hello")
set_kind("binary")
add_files("src/*.kt")
2. Target kinds
target("app") set_kind("binary") -- Kotlin/Native executable
target("mylib") set_kind("static")
target("mydyn") set_kind("shared")
3. Toolchain
Kotlin/Native must be installed separately — it's not bundled with xmake.
xmake f --toolchain=kotlin-native
xmake f --toolchain=kotlin-native --sdk=/opt/kotlin-native-prebuilt-linux-x86_64-1.9.0
Download the compiler from kotlinlang.org/docs/native-overview.html and point --sdk at it.
4. Targets
Kotlin/Native supports many platforms:
xmake f -p linux -a x86_64 --toolchain=kotlin-native
xmake f -p macosx -a arm64 --toolchain=kotlin-native
xmake f -p windows -a x86_64 --toolchain=kotlin-native
xmake f -p iphoneos -a arm64 --toolchain=kotlin-native
5. Interop with C
Kotlin/Native has a cinterop mechanism for binding C libraries. At the xmake level, link native static libs the usual way:
target("app")
set_kind("binary")
add_files("src/*.kt")
add_deps("mycdep") -- C static library target
cinterop configuration (the .def files) is Kotlin-side — see Kotlin/Native docs.
Pitfalls
- Use case is narrow. Most real-world Kotlin is JVM / Android. If that's what you need, Gradle is the right tool, not xmake.
- Large toolchain download. Kotlin/Native is ~1GB. Cache
--sdkglobally viaxmake g --sdk=.... - Slow first compile. Kotlin/Native's cold start is notoriously slow. Expect longer builds than Rust/Go for equivalent code.
When to branch out
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.

xmake-kotlin is a skill published in the GitHub repository xmake-io/xmake-skills (24 stars, last pushed 18d ago), licensed Apache-2.0. It adds 46 tokens to every session and 640 once invoked, about $0.0002 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 2026-08-30.
