What is BOB-Gemini-Free AGENTS.md?

Project instructions for BOB Gemini Free, a local Go gateway that lets clients using several AI API formats communicate with Google's Gemini service. They describe the project overview, layout, and development commands.

Use them when developing or maintaining the gateway, its OpenAI-, Anthropic-, and Gemini-compatible endpoints, embedded Go library, build process, or project structure.

They give coding agents the context and conventions needed to work safely in this codebase.

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	$0.02608	$0.02608
Opus 5.5	$0.01043	$0.01043

Security

Grade B, and why

BOB-Gemini-Free AGENTS.md scanned grade B with 1 finding 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 2mo 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.

AGENTS.md — AI Agent Guidelines for BOB Gemini Free

Welcome, AI Agent! This document provides technical architecture, build instructions, directory layouts, and execution workflows for automated agents (Cursor, Windsurf, Claude Code, Codex CLI, Aider, OpenHands, Devin, Roo Code) interacting with the BOB Gemini Free codebase.

1. Project Overview

BOB Gemini Free (Break Ordinary Boundaries) by ABCsteps (abcsteps.com) and Divyanshu Singh Chouhan (@div197) is a high-performance, single-binary local AI gateway written in Go.

It translates three major protocol standards into Google's internal web RPC protocol (batchexecute / streamGenerateContent):

OpenAI Standard: POST /v1/chat/completions, POST /v1/responses (with output_text), POST /v1/tokens/count, GET /v1/models, GET /v1/models/{model}, POST /v1/images/generations
Anthropic Standard: POST /v1/messages (Claude Code CLI with complete SSE stream lifecycle and prompt caching counters)
Google Gemini Standard: GET /v1beta/models, POST /v1beta/models/{target} (including generateContent, streamGenerateContent, and :countTokens)
Embedded Go Library: pkg/gateway (import "github.com/div197/bob-gemini-free/pkg/gateway")

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.
