What is OpenBridge AGENTS.md?

A set of project instructions for OpenBridge, a macOS app for managing local coding agents and their settings. It explains the repository layout, development commands, and rules for keeping the shared agent software separate from app-specific features.

Use it when working on OpenBridge's macOS app, embedded web interface, sandbox virtual machine, local agent runtime, skills, schedules, or configuration management.

It gives coding agents a map of the project and reduces the risk of changing the wrong component or adding app-specific behavior to shared software.

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	$0.01163	$0.01163
Opus 5.5	$0.00465	$0.00465
Sonnet 5.5	$0.00233	$0.00233

Security

Grade A, and why

OpenBridge 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 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.

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.

Project Overview

OpenBridge is a macOS-first local agent chat app. It preserves the native macOS chat experience, embedded WebViews, skills, schedules, memory, computer-use workflows, and sandbox VM execution while removing login, payment, usage, backend-hosted LLM clients, clipboard history, and Lens/screenshot capture features.

The local agent runtime is built around vendored kwwk in this repository. Keep kwwk broadly useful as an agent SDK; avoid adding OpenBridge-specific business concepts to it unless they are general SDK primitives.

Agent Guide

Do not generate markdown documents after files changed; output directly.
Do not add comments solely for chat information; comments must have long-term value.
Limit batch sizes to about 100 items when generating large outputs.
Clean up temporary files after completing generation tasks.

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.
