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.

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 | $0.00000 | $0.01068 |
| Opus 5 | $0.00000 | $0.00534 |
| Sonnet 5 | $0.00000 | $0.00214 |
| Haiku 4.5 | $0.00000 | $0.00107 |
Grade A, and why
msys2-windows 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 2d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MSYS2 & Windows Development Environment
⚠️ CRITICAL: MSYS2 bash only — no PowerShell, no cmd
Terminal: C:\msys64\usr\bin\bash.exe (MSYS2 UCRT64) for all dev work: cargo, git, scripts, and any verification you run locally.
CI on GitHub uses its own runner environment; locally, stay in MSYS2 bash (see rust-architect.mdc, git-push.md).
Windows 11 (24H2+ / builds 26100+; e.g. 26200)
- Windows Defender can slow or lock files under
target/— optional exclusion for the repotargetfolder (or whole repo) if builds/tests stall. - Long paths: if
cargoreports path length issues, enable long paths in Windows or keep the repo on a shorter path (e.g.S:\rust\poolAIis fine). rust-toolchain.tomlpinsx86_64-pc-windows-gnu; the active host may still be MSVC (rustc -vV→host: …-msvc). For GNU linking you need MSYS2gcc/x86_64-w64-mingw32-gcconPATH(see.cargo/config.toml). If the host is MSVC-only, align withrustup override/ installed toolchains.

Tooling Checks (rustc/cargo/clippy/cl)
- Version sanity (run once per session if something fails):
rustc --versioncargo --versioncargo clippy --version
- MSRV note (cloud-sdk/AWS SDK):
cloud_mock_integrationrequiresrustc >= 1.88. If yourrustc --versionis lower (e.g. 1.87.0), installrustup+the toolchain fromrust-toolchain.tomlor upgrade the MSYS2 Rust package before running cloud tests. - MSVC
cl.exenote:- Default toolchain is GNU (
x86_64-pc-windows-gnu);cl.exeis usually not needed. - If you switch to an MSVC host/toolchain, use a Visual Studio / MSVC environment where
clis onPATH, then runcargofrom that same environment (still avoid ad-hoc PowerShell/cmd-only workflows for this repo).

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.

msys2-windows is a cursor rule published in the GitHub repository platinoff/poolAI (4 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,068 tokens. 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 2026-08-31.
