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 | $0.00134 | $0.00620 |
| Opus 5 | $0.00067 | $0.00310 |
| Sonnet 5 | $0.00027 | $0.00124 |
| Haiku 4.5 | $0.00013 | $0.00062 |
Grade A, and why
choose-stack 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.
What it actually says
Tools Reference
Release & Versioning
- sr (semantic-release) automated versioning, changelog, GitHub releases, AI-powered commits/rebase/review/PR generation (multi-backend: Claude, Copilot, Gemini)
Documentation & Demos
- teasr automated screenshot/GIF capture (web, terminal, screen)
- fsrc sync source code into markdown files
Code Generation
- oag (openapi-generator) OpenAPI → TypeScript/React/Python clients
Rust
- cargo build system and package manager
- clippy linting and idiomatic Rust checks
- clap command-line argument parsing
- cross cross-compilation for ARM/musl targets
- cargo-insta snapshot testing
Go
- wails desktop applications with Go backend and web frontend
- golangci-lint comprehensive Go linting
- go-rod browser automation
Node
- ncc compile Node.js modules into single files
- tsdown TypeScript bundler (Rolldown-based)
- biome linting and formatting for JS/TS
- turbo monorepo build system (task caching, parallel execution)
Python
- uv package manager and virtual environment tool
- ruff linting and formatting
- ty static type checking
- pytest testing framework
- pydantic data validation with type annotations
- fastapi async web framework
- logging (stdlib) foundation layer; prefer over loguru (
logging.getLogger(__name__)) - structlog structured/JSON logging on top of stdlib; use when services need machine-readable output
- loguru quick scripts and one-off CLIs only; never in libraries or production services
- opentelemetry tracing, metrics, and log export (otel-sdk + otel-exporter-otlp); stdlib logging has first-class OTel support, structlog works transitively
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.

choose-stack is a skill published in the GitHub repository urmzd/dotfiles (3 stars, last pushed 20d ago), licensed Apache-2.0. It adds 134 tokens to every session and 620 once invoked, about $0.0007 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 2026-08-31.
