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 | $0.00080 | $0.01877 |
| Opus 5 | $0.00040 | $0.00938 |
| Sonnet 5 | $0.00016 | $0.00375 |
| Haiku 4.5 | $0.00008 | $0.00188 |
Grade C, and why
aios-interception-runtime scanned grade C with 2 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 3d 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.

RTK + Caveman 社区工具安装配置指南
AIOS 原生拦截运行时已废弃。Token 压缩改由社区维护的 RTK 和 Caveman 处理。
- RTK (https://github.com/rtk-ai/rtk) — Rust CLI 代理，过滤和压缩命令输出 60-90%。单二进制，<10ms 开销，100+ 支持命令。本地运行，无外部服务。
- Caveman (https://github.com/JuliusBrussee/caveman) — Claude Code skill/插件，压缩 agent 输出 token ~75%。保持技术准确性，仅压缩表述风格。本地 prompt skill。
一、自动安装
aios init 会自动检测并安装 RTK + Caveman（带有安装确认提示）：
# 交互式安装（会提示确认）
node scripts/aios.mjs init --agent <claude|codex|gemini|opencode>
# 跳过确认提示（用于 CI/无人值守场景）
node scripts/aios.mjs init --yes-compression-tools
# 仅检测不安装
node scripts/aios.mjs init --dry-run
安装后 aios init 会自动运行 rtk init -g 为检测到的客户端注册 hook/plugin。
二、手动安装
RTK
# macOS (推荐)
brew install rtk
# Linux / macOS / WSL
curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh
# Windows (下载预编译二进制)
# 从 https://github.com/rtk-ai/rtk/releases 下载 rtk-x86_64-pc-windows-msvc.zip
# 解压到 PATH 中的目录（如 C:\Users\<you>\.local\bin）
# Cargo
cargo install --git https://github.com/rtk-ai/rtk
# 验证
rtk --version # 应显示 rtk 0.28.2+
rtk gain # 查看 token 节省统计
RTK 初始化
rtk init -g # Claude Code / Copilot (默认)
rtk init -g --gemini # Gemini CLI
rtk init -g --codex # Codex (OpenAI)
rtk init --agent cursor # Cursor
rtk init --agent windsurf # Windsurf
rtk init --agent cline # Cline / Roo Code
rtk init --agent hermes # Hermes
Caveman
# macOS / Linux / WSL / Git Bash
curl -fsSL https://raw.githubusercontent.com/JuliusBrussee/caveman/main/install.sh | bash
# Windows (PowerShell 5.1+)
$installer = Join-Path $env:TEMP 'caveman-install.ps1'
irm https://raw.githubusercontent.com/JuliusBrussee/caveman/main/install.ps1 -OutFile $installer
powershell -NoProfile -ExecutionPolicy Bypass -File $installer
Remove-Item $installer -Force
安装后约 30 秒。需要 Node >= 18。会自动检测已安装的客户端并跳过没有的。 安全重复运行。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aios-interception-runtime is a skill published in the GitHub repository rexleimo/aios (52 stars, last pushed 4d ago), licensed MIT. It adds 80 tokens to every session and 1,877 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
