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 | $0.00052 | $0.00911 |
| Opus 5 | $0.00026 | $0.00456 |
| Sonnet 5 | $0.00010 | $0.00182 |
| Haiku 4.5 | $0.00005 | $0.00091 |
Grade A, and why
xmake-swift 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 12d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building Swift with Xmake
Xmake builds Swift through swiftc and integrates with Xcode on Apple platforms. Use it when you want the same xmake.lua to drive a project that mixes Swift with C/C++/Objective-C.
1. Minimal project
xmake create -l swift -t console hello
cd hello
xmake run
add_rules("mode.debug", "mode.release")
target("hello")
set_kind("binary")
add_files("src/*.swift")
2. Target kinds
target("app") set_kind("binary")
target("mylib") set_kind("static")
target("mydyn") set_kind("shared")
3. Swift ↔ C++/Objective-C interop (v3.0.5+)
Xmake supports automatic Swift-interop C++ header generation through the swift.interop target value.
Call Swift from C++
target("myswift")
set_kind("static")
add_files("src/*.swift")
set_values("swift.interop", "cxx") -- or "objc"
set_values("swift.modulename", "MySwift") -- C++ namespace name
target("app")
set_kind("binary")
add_files("src/main.cpp")
add_deps("myswift")
set_languages("c++17")
Xmake generates a C++ header with #include "MySwift-Swift.h" style, exposing Swift types under MySwift:: namespace.
Interop modes
"objc"— Objective-C interop (classic, works since early Swift)"cxx"— C++ interop (Swift 5.9+ required)
Resolving duplicate main
When both Swift and C++ have a main, Swift's usually wins. Force the C++ one:
set_values("swift.interop.cxxmain", true)
4. Apple platforms
xmake f -p macosx -a arm64
xmake f -p iphoneos -a arm64
xmake f -p iphonesimulator -a arm64
xmake
Xmake picks up Xcode automatically. Pin SDK version with --xcode_sdkver=16.2, deployment target with --target_minver=12.0.
5. Flags
target("app")
add_files("src/*.swift")
add_scflags("-O") -- passed to swiftc
add_ldflags("-Wl,-dead_strip")
add_scflags = Swift compiler flags.
6. Toolchain
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-swift is a skill published in the GitHub repository xmake-io/xmake-skills (24 stars, last pushed 20d ago), licensed Apache-2.0. It adds 52 tokens to every session and 911 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.
