rust-architect

A project rulebook for developing PoolAI in Rust, with specific Windows tooling, build targets, testing, formatting, and code-quality checks.

In plain words
What is it for?
Use it when working on PoolAI's Rust source, JavaScript admin interface, TypeScript end-to-end tests, toolchain setup, API checks, or pre-push validation.
Why use it?
It keeps development consistent by defining which languages and tools belong in each part of the project and which checks should run before code is pushed.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 3,367 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

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.

Security

Grade A, and why

rust-architect 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 yesterday.

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.

Rust Architect Rules - PoolAI Development

⛔ Runtime stack (non-negotiable)

  • Product: Rust only (src/, tests/, crates/). Admin UI: src/ui/ (JavaScript). E2E: e2e/ (TypeScript).
  • No Python in runtime, ML, or API layers. Do not cite archived docs that suggest Python sidecars.
  • Dev audit: cargo run --bin poolai-openapi-gap-audit — OpenAPI vs Axum routes (src/bin/poolai_openapi_gap_audit.rs).
  • Full policy: .cursor/rules/runtime-stack-policy.mdc (alwaysApply).

🏗️ Rust Architect Workflow

⚠️ Термінал: канонічно MSYS2 bash; автоматизація — з контекстом

Для людини (git push, довгі збірки, уникнення index.lock / CreateFileMapping на Windows)
Terminal: C:\msys64\usr\bin\bash.exeзовнішнє вікно MSYS2 UCRT64 (див. .cursor/commands/git-push.md).
Environment: rust-toolchain.toml — канал 1.92.0, ціль x86_64-pc-windows-gnu + компоненти rustfmt, clippy. Якщо rustup show показує MSVC у каталозі репо, вирівняй toolchain: rustup override set 1.92.0-x86_64-pc-windows-gnu у корені репо (або збірка в UCRT64 за README).

Локальні перевірки (cargo test, fmt, clippy) — у тому ж MSYS2 bash, що й git (див. блок у git-push.md). GitHub Actions працює на власному раннері; це не привід використовувати PowerShell/cmd у цьому репо.

Windows 11 (збірки 26100+, зокрема 26200): за гальмування збірок — перевірити сканування target/ (Defender); при нестачі місця — cargo clean або винести артефакти через CARGO_TARGET_DIR.

target/ і ліміт дискового простору

Щоб не переповнювався диск і не падали лінкер / тести через ENOSPC або фрагментацію вільного місця:

  • Політика (м’які пороги за замовчуванням): тримати ≥ 12 GiB вільних на томі, де лежить репозиторій (або CARGO_TARGET_DIR); каталог target/ доречно тримати ≤ ~48 GiB для цього монорепо — інакше cargo clean або окремий том під CARGO_TARGET_DIR.
  • Перевірка перед важкими прогонами: bash scripts/check_target_disk.sh (лише попередження) або з жорстким фейлом: bash scripts/check_target_disk.sh --enforce / POOLAI_ENFORCE_DISK_LIMIT=1. Пороги: POOLAI_MIN_FREE_DISK_GB, POOLAI_MAX_TARGET_DIR_GB (див. шапку скрипта).
  • Зменшення тиску на диск: CARGO_INCREMENTAL=0 для разових повних матриць; -j 1 для лінкера на Windows (уже в доках); не тримати одночасно кілька величезних target/ на одному томі.

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.

rust-architect 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 3,367 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.
