In plain words
What is it for?
Use them when changing the bridge server, request handler, Frida implementations, health endpoint, or related tests.
Why use it?
They give coding agents the project structure, interfaces, and important modules needed to work safely in the repository.

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.

Security

Grade A, and why

barbatos 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 9d 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.

GEMINI.md — Barbatos JSON-RPC Bridge

Project Overview

barbatos is a high-performance Kotlin Multiplatform (KMP) JSON-RPC Bridge designed for Android and iOS runtime debugging via Frida. It replaces the legacy Python bridge and TUI with a unified, native binary that exposes a standardized JSON-RPC 2.0 API over HTTP.

The bridge enables both human developers (via TUI or Web) and AI agents (via MCP) to interact with live application memory, inspect objects, and hook methods with zero setup.

Technical Architecture

The project follows a modular, interface-driven design to ensure testability and multi-platform support.

                                             ┕━ NativeFridaBridge (Prod/Native)

Key Modules

  • Server (src/commonMain/kotlin/server/): Built on Ktor (CIO engine). Exposes /ping for health checks and /rpc for all debugger operations.
  • RPC Handler (src/commonMain/kotlin/rpc/): Orchestrates request parsing, validation against JSON-RPC 2.0 standards, and routing to the active FridaBridge implementation.
  • Native Bridge (src/unixMain/kotlin/bridge/): The core engine. Interacts with Frida Core (C API) using Kotlin Native CInterop. It statically links libfrida-core.a and manages process attachment and script injection.
  • Resources (src/commonMain/resources/): Contains the JavaScript agents (agent.js, agent.objc.js) that are injected into the target processes.

Build & Development

Requirements

  • macOS ARM64 or Linux (x64/ARM64).
  • JDK 17+.
  • Frida Devkit: Headers and static libraries managed by our automation.

Setup & Run

# 1. Prepare environment (Download Frida Core SDK)
./scripts/download_frida_devkit.sh

# 2. Compile Release Binary
./gradlew linkReleaseExecutableMacosArm64

# 3. Start Bridge
./build/bin/macosArm64/releaseExecutable/barbatos.kexe

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.
