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 | $0.00107 | $0.01981 |
| Opus 5 | $0.00053 | $0.00991 |
| Sonnet 5 | $0.00021 | $0.00396 |
| Haiku 4.5 | $0.00011 | $0.00198 |
Grade A, and why
xmake-trybuild 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 10d 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Xmake TryBuild — Drive Third-Party Build Systems
trybuild lets xmake invoke another build system (CMake, Autotools, Meson, …) while still providing its own platform/toolchain detection, cross-compile support, and incremental-build wrappers. Use it when you need to build an upstream project that doesn't use xmake.lua, but still want xmake's cross-compilation ergonomics.

1. Auto-detect mode
Run plain xmake inside a project root that has a recognized file (CMakeLists.txt, configure, Makefile, meson.build, …). Xmake prompts before building:
$ cd libpng-1.6.35
$ xmake
note: CMakeLists.txt found, try building it (pass -y or --confirm=y/n/d to skip confirm)?
please input: y (y/n)
-- Configuring done
-- Generating done
...
output to /Users/ruki/Downloads/libpng-1.6.35/build/artifacts
build ok!
Add -y to skip the prompt in CI:
xmake -y
Artifacts land under build/artifacts/.
2. Force a specific backend
When a project ships multiple build systems (e.g. both configure and CMakeLists.txt):
xmake f --trybuild=cmake
xmake
Once set, subsequent xmake / xmake clean calls use the configured backend — no re-prompting.
3. Standard xmake commands work
Once trybuild is configured, normal xmake commands drive the upstream build:
xmake # build
xmake --rebuild # force full rebuild
xmake clean # clean objects
xmake clean --all # wipe everything (configure cache, artifacts)
xmake f -m debug # switch to debug build
xmake f -m release
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-trybuild is a skill published in the GitHub repository xmake-io/xmake-skills (24 stars, last pushed 17d ago), licensed Apache-2.0. It adds 107 tokens to every session and 1,981 once invoked, about $0.0005 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.
