What is vibeshell AGENTS.md?

A project guide for VibeShell, a desktop SSH and SFTP terminal built with a Rust backend and a React frontend. It documents the application structure and how its frontend communicates with its backend.

Use it when working on VibeShell features involving SSH, SFTP, terminals, tunnels, session recording, local shells, AI tools, the React interface, or the Rust backend.

It gives coding agents the project’s architecture and important library constraints before they change the code. This reduces the chance of placing logic in the wrong layer or using incompatible SSH behavior.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02662	$0.02662
Opus 5.5	$0.01065	$0.01065
Sonnet 5.5	$0.00532	$0.00532

Security

Grade A, and why

vibeshell AGENTS.md 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 1mo 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 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.
