Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00060 | $0.02217 |
| Opus 5 | $0.00030 | $0.01108 |
| Sonnet 5 | $0.00012 | $0.00443 |
| Haiku 4.5 | $0.00006 | $0.00222 |
Grade A, and why
xmake-dev 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 — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Developing Xmake Itself
This skill is for working on the xmake-io/xmake source tree — not for projects that use xmake. Xmake is split into two layers:
- Lua layer (
xmake/) — most of xmake's behavior: actions, modules, rules, toolchains, sandbox. Editable without recompiling. - Native C core (
core/src/xmake/) — the Lua runtime and xmake extension C APIs (os.*,io.*,process.*,fwatcher, etc.), plus tbox. Changes here require rebuilding thexmakebinary.
1. Get the source
git clone --recursive https://github.com/xmake-io/xmake.git
cd xmake
Use --recursive — xmake bundles tbox and other submodules under core/src.
2. Build the xmake binary
Linux / macOS
./configure
make -j
Artifacts land in core/build/xmake (also symlinked via build/xmake).
Windows
cd core
xmake
This uses an existing xmake to bootstrap the new one; the resulting binary is core/build/xmake.exe.
Clean rebuild
make clean
./configure && make -j
On Windows: cd core && xmake clean && xmake.
3. Load the local source tree
So the xmake command in your shell points at the freshly built binary and loads Lua scripts from your checkout instead of the installed ~/.xmake:
Linux / macOS
source scripts/srcenv.profile
xmake --version
This script:
- aliases
xmaketo./core/build/xmake(or./build/xmake) - sets
XMAKE_PROGRAM_FILEto that binary - sets
XMAKE_PROGRAM_DIRto./xmake(the Lua script tree) - aliases
xrepotoscripts/xrepo.sh - prints the resolved
programdir/programfileso you can verify
Windows
scripts\srcenv.bat
Opens a new shell pre-configured with XMAKE_PROGRAM_DIR and XMAKE_PROGRAM_FILE, and core\build on PATH.
Manual alternative
If you do not want to source the script, set the env vars yourself:
export XMAKE_PROGRAM_DIR=/path/to/xmake/xmake # the Lua tree
export XMAKE_PROGRAM_FILE=/path/to/xmake/core/build/xmake
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-dev is a skill published in the GitHub repository xmake-io/xmake-skills (23 stars, last pushed 16d ago), licensed Apache-2.0. It adds 60 tokens to every session and 2,217 once invoked, about $0.0003 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.
