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 | $0.03063 | $0.03063 |
| Opus 5 | $0.01532 | $0.01532 |
| Sonnet 5 | $0.00613 | $0.00613 |
| Haiku 4.5 | $0.00306 | $0.00306 |
Grade B, and why
FlyEnv AGENTS.md scanned grade B 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Expected in a hook, worth knowing in a rule or an instructions file.

FlyEnv - AI Agent Development Guide
Project Overview
FlyEnv is an All-In-One Full-Stack Environment Management Tool built with Electron and Vue 3. It provides a lightweight, modular development environment manager for Windows, macOS, and Linux, allowing developers to install and manage Apache, PHP, Node.js, Python, databases, and more—running natively without Docker.

Project Architecture
FlyEnv follows Electron's multi-process architecture with three main components:
1. Main Process (/src/main)
Acts as a command relay station between the renderer and fork processes.
Key Files:
index.ts- Entry point, initializes LauncherLauncher.ts- Application bootstrap, single-instance lock, event handlingApplication.ts- Main application controller, window management, IPC handling
Core Managers:
WindowManager- Browser window creation and managementTrayManager- System tray functionalityMenuManager- Application menusConfigManager- Configuration persistenceForkManager- Forked process managementNodePTY- Terminal PTY handling
2. Forked Asynchronous Process (/src/fork)
Executes all heavy commands asynchronously to prevent main thread blocking.
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.

FlyEnv AGENTS.md is an instructions file published in the GitHub repository xpf0000/FlyEnv (3,191 stars, last pushed 2d ago), licensed BSD-3-Clause. It adds 3,063 tokens to every session, about $0.0153 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
