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 | $0.00042 | $0.01204 |
| Opus 5 | $0.00021 | $0.00602 |
| Sonnet 5 | $0.00008 | $0.00241 |
| Haiku 4.5 | $0.00004 | $0.00120 |
Grade A, and why
xmake-toolchains 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Xmake Toolchains
A toolchain bundles a compiler, linker, archiver, and related tools. You pick one per configure.
Listing and switching
xmake show -l toolchains # list available toolchains (~77 of them)
xmake f --toolchain=clang
xmake f --toolchain=gcc-11 # gcc-12 .. gcc-16 exist as well
xmake f --toolchain=mingw --mingw=/opt/llvm-mingw
xmake f --toolchain=msvc --vs=2022
Notable ones beyond the usual gcc/clang/msvc:
| Toolchain | For |
|---|---|
zigcc |
C/C++ through zig cc, a cross compiler with no sysroot — @see the xmake-zigcc skill |
zig |
Zig code |
muslcc |
musl-based cross toolchains, downloaded on demand |
emcc / wasi |
WebAssembly (emscripten / WASI) |
cosmocc |
build-once run-anywhere binaries |
dotnet |
C# and the .NET SDK |
cuda |
nvcc / nvc / nvc++ / nvfortran |
filc |
a memory-safe C/C++ implementation |
ascendc |
Huawei Ascend C (bisheng driver) |
armclang / iar / sdcc |
embedded compilers |
Pointing at an sdk
xmake f --toolchain=clang --sdk=/opt/llvm-18 # the sdk root
xmake f --toolchain=gcc --bin=/opt/gcc/bin # only the bin directory
xmake f --toolchain=clang --cc=clang-18 --cxx=clang++-18 # individual tools
--sdk is the standard knob: xmake derives bin/, include/ and lib/ from it.
In xmake.lua:
set_toolchains("clang")
target("app")
set_toolchains("gcc-11") -- override per target
Cross-compilation
Android
xmake f -p android --ndk=~/android-ndk-r26 -a arm64-v8a
xmake
Arch options: armeabi-v7a, arm64-v8a, x86, x86_64.
iOS / macOS
xmake f -p iphoneos -a arm64
xmake f -p macosx -a arm64 # Apple Silicon
Windows from Linux (mingw)
xmake f -p mingw --mingw=/usr/x86_64-w64-mingw32 -a x86_64
WebAssembly
xmake f -p wasm --toolchain=emcc
Generic cross-gcc
xmake f -p cross --sdk=/opt/my-sdk --cross=arm-linux-gnueabihf- -a arm
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-toolchains is a skill published in the GitHub repository xmake-io/xmake-skills (23 stars, last pushed 16d ago), licensed Apache-2.0. It adds 42 tokens to every session and 1,204 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.
