VibeTunnel is a tool that displays a computer terminal in a web browser, allowing users to access terminal sessions and monitor coding agents remotely. It is for developers who want to check agents, builds, or shared terminal sessions from another device, and the catalogue contains instructions, commands, and an MCP integration for it.

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 | $0.00137 | $0.00137 |
| Opus 5 | $0.00068 | $0.00068 |
| Sonnet 5 | $0.00027 | $0.00027 |
| Haiku 4.5 | $0.00014 | $0.00014 |
Grade A, and why
vibetunnel GEMINI.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 10d 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
Gemini Operational Instructions
When I am operating within this project, I must adhere to the following instructions:
- Read
claude.md: Before performing any task, I must first read theclaude.mdfile located in the current working directory. - Contextual Awareness: If the current working directory is a subfolder, I must read all
claude.mdfiles found in the current folder and all of its parent directories up to the project root. This ensures I have the full context, from the general project-level instructions to the specific subdirectory instructions.
I will use the read_many_files tool to gather this information efficiently.
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.

vibetunnel GEMINI.md is an instructions file published in the GitHub repository amantus-ai/vibetunnel (4,651 stars, last pushed 1mo ago), licensed MIT. It adds 137 tokens to every session, 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 2026-08-30.
