bex-web-services

bex-web-services is a skill for Claude Code, Codex from bex-co/bex. It costs 73 tokens per session (1,653 once invoked), scanned A, original, Apache-2.0.

A skill for configuring and troubleshooting hosted web services on bex. It covers how applications receive traffic, pass health checks, use domains and storage, and move through deployment.

In plain words
What is it for?
Use it to configure ports, TLS, health checks, custom domains, automatic or CI-gated deployments, pull-request previews, persistent disks, and deployment lifecycle settings.
Why use it?
It helps diagnose failed deployments, port or health-check problems, and configuration issues around domains, storage, previews, and rollbacks.

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-web-services 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 Web Services

This skill covers Web Service behavior on bex: how traffic reaches your process, how deploys go live, and how optional features (domains, disks, auto-deploy) interact. Use it alongside Blueprint and networking skills when wiring render.yaml or Dashboard settings.

When to Use

  • Configuring or debugging port binding, PORT, or multi-port web services
  • TLS/HTTPS expectations at the edge vs inside the container
  • Health checks blocking or rolling back deploys
  • Custom domains, DNS, and certificate provisioning
  • Auto-deploy, CI-gated deploys, and PR preview generation
  • Persistent disks and their impact on scaling and zero-downtime
  • Deploy lifecycle: build, pre-deploy, swap, drain, rollback, shutdown delay

Deeper patterns live under references/ (health checks, domains, deploy phases).

Before configuring or troubleshooting deploys and health checks, read references/deployments.md. Before attaching or changing a persistent disk, read references/persistent-disks.md. Before configuring or troubleshooting private connectivity or additional ports, read references/private-networking.md.

Port Binding

  • Listen on 0.0.0.0 (all interfaces). Binding only to localhost or 127.0.0.1 prevents bex’s proxy from reaching your app.
  • Use the PORT environment variable for the HTTP listen port. bex sets it for you; the default is often 10000 and you can change the configured value in the service Settings in the Dashboard.
  • Reserved ports (do not bind your application to these for normal traffic): 18012, 18013, 19099.

Multi-port Web Services

  • Only one port receives public HTTP traffic: the port aligned with PORT.
  • Additional open ports are reachable on bex’s private network only (not from the public internet through the same public URL pattern).

TLS and HTTPS

  • TLS terminates at bex’s edge. The edge speaks HTTPS to clients; your process typically receives plain HTTP on PORT.
  • HTTPS redirect for clients is handled by the platform; users hitting HTTP are redirected appropriately at the edge.
  • Do not terminate TLS inside the app for the primary public listener unless you have a rare, explicit need—standard Web Services assume HTTP behind the proxy.

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.

bex-web-services is a skill published in the GitHub repository bex-co/bex (577 stars, last pushed today), licensed Apache-2.0. It adds 73 tokens to every session and 1,653 once invoked, about $0.0003 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.
