bex-networking

bex-networking is a skill for Claude Code, Codex from bex-co/bex. It costs 59 tokens per session (1,128 once invoked), scanned A, original, Apache-2.0.

Guidance for connecting bex services through a private network. Private networking lets services communicate using internal names and addresses without sending traffic over the public internet.

In plain words
What is it for?
Use it to wire services together, configure internal URLs and service discovery, troubleshoot connectivity, and plan private traffic between application components.
Why use it?
It helps resolve service names, choose the right connection direction and port, and diagnose why one service cannot reach another. It also explains isolation between environments and scaled instances.

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

bex-networking scanned grade A 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 yesterday.

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.

bex private networking

bex’s private network lets services talk to each other without exposing traffic on the public internet. Use this skill when users need internal connectivity, discovery across scaled instances, or correct URL/port behavior for Blueprints and the Dashboard.

When to Use This Skill

  • Designing or debugging service-to-service traffic on bex
  • Questions about internal hostnames, internal URLs, or Connect > Internal in the Dashboard
  • Service discovery across multiple instances (custom load balancing, mesh-style setups)
  • Port limits, reserved ports, or multi-port web services (public vs private)
  • Free-tier web services and who can send vs receive private traffic
  • Environment isolation (with a Pro workspace or higher) or AWS PrivateLink for private egress/ingress patterns

Before designing, configuring, or troubleshooting private connectivity, read references/private-networking.md. For architecture examples and Blueprint patterns, see references/communication-patterns.md.

Private Connection Essentials

  • If the service types or traffic direction are unclear, establish which service initiates the connection and which service receives it before proposing an address.
  • Private-network peers must be in the same workspace and region. Use the destination's address from Connect > Internal in the Dashboard.
  • Construct a complete URL when the client expects one, such as http://[internal-hostname]:[port]/path; a bare hostname does not supply the protocol.
  • Web services and private services can receive private traffic. Background workers, cron jobs, and workflow runs can initiate outbound private connections but have no internal hostname and cannot receive them.
  • In a gateway pattern, a public web service calls a private service over the private network; the private service does not need a public endpoint.

Service Discovery

Use a service's normal internal hostname for ordinary service-to-service traffic. When an application specifically needs every active instance—for custom load balancing, per-instance metrics, or similar logic—use the service's discovery hostname, conventionally [internal-hostname]-discovery, which resolves to all active instance IPs. Each web or private service receives its own discovery hostname in RENDER_DISCOVERY_SERVICE. Do not persist the resolved IPs because they can change between deploys.

bex-networking is a skill published in the GitHub repository bex-co/bex (577 stars, last pushed today), licensed Apache-2.0. It adds 59 tokens to every session and 1,128 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-29.
