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 | $0.00094 | $0.01501 |
| Opus 5 | $0.00047 | $0.00750 |
| Sonnet 5 | $0.00019 | $0.00300 |
| Haiku 4.5 | $0.00009 | $0.00150 |
Grade A, and why
xmake-env-vars 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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Xmake Environment Variables
Xmake reads a handful of XMAKE_* environment variables to relocate config, enable profiling, load user-wide defaults, and more. They take precedence over the matching xmake g global setting when both are present.

Reference
Paths
| Variable | Purpose | Default |
|---|---|---|
XMAKE_PROGRAM_DIR |
Where xmake's Lua scripts live | xmake install dir |
XMAKE_PROGRAM_FILE |
Which xmake binary to use |
resolved from PATH |
XMAKE_GLOBALDIR |
Root for xmake g global config (creates .xmake/ inside) |
~ |
XMAKE_CONFIGDIR |
Where per-project .xmake/ cache goes |
project dir |
XMAKE_TMPDIR |
Temp scratch | /tmp/.xmake / %TEMP%\.xmake |
XMAKE_RAMDIR |
Optional ramdisk for temp files — fastest | unset |
XMAKE_PKG_INSTALLDIR |
Package install root | $XMAKE_GLOBALDIR/.xmake/packages |
XMAKE_PKG_CACHEDIR |
Package cache dir | $XMAKE_GLOBALDIR/.xmake/cache |
XMAKE_LOGFILE |
Log everything xmake does to this file | unset |
Typical uses:
# Use a local source checkout of xmake (developing xmake itself — see xmake-dev skill)
export XMAKE_PROGRAM_DIR=/path/to/xmake/xmake
export XMAKE_PROGRAM_FILE=/path/to/xmake/core/build/xmake
# Keep project .xmake out of the repo root
export XMAKE_CONFIGDIR=/tmp/myproject-xmake
# Put packages on a fast disk
export XMAKE_PKG_INSTALLDIR=/mnt/fast/xmake-packages
export XMAKE_PKG_CACHEDIR=/mnt/fast/xmake-cache
# Ram-disk temp for crazy-fast configures
export XMAKE_RAMDIR=/dev/shm/xmake
Output / behavior
| Variable | Values | Purpose |
|---|---|---|
XMAKE_COLORTERM |
nocolor / color8 / color256 / truecolor |
Force color mode |
XMAKE_PROFILE |
stuck / trace / perf:call / perf:tag / perf:process |
Profiling / stuck debug — see xmake-troubleshooting |
XMAKE_ROOT |
y |
Allow running as root (off by default — unsafe) |
XMAKE_LOGFILE |
path | Mirror xmake output to a log file |
XMAKE_THEME |
theme name | Equivalent to xmake g --theme=... |
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-env-vars is a skill published in the GitHub repository xmake-io/xmake-skills (24 stars, last pushed 19d ago), licensed Apache-2.0. It adds 94 tokens to every session and 1,501 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.
