Maintaining wait-on at agent speed: AI, npm supply-chain risk, and a Rust engine

I recently joined Jeff Barczewski, who created wait-on in 2015, as a maintainer of the project. Jeff and I met in the food line at JSConf US in 2013 and have been friends ever since. We've spoken at and attended as many tech conferences together as we can, at least one a year. Working on Jeff's project together is a new chapter of that.

Setting the model for nicknisi/consultant's gpt5-server MCP

The gpt5-server MCP in the nicknisi/consultant plugin does not read a model from an environment variable. It accepts model as a per-call argument, with 'gpt-5' hardcoded as the Zod default and the || fallback in callGPT5.

So you set it one of three ways.

1. Per call (cleanest)

Pass model in the tool args when invoking it directly:

Claude Code GitHub Actions — Label-Driven CI Agent

A set of GitHub Actions workflows that use claude-code-action enhanced with the Compound Engineering plugin to automate issue triage, planning, fixing, and end-to-end resolution — all driven by GitHub issue labels.

Why Compound Engineering?

These workflows go beyond basic Claude Code Action by integrating the Compound Engineering plugin — a set of slash commands that give Claude structured, battle-tested workflows for planning and implementation:

Let's say we've removed a Lambda Layer from the Lambda Console and are no longer able to perform operations using the Amplify CLI.

An error occurred fetching the latest layer version metadata for ""

When you delete a layer version, you can no longer configure functions to use it.
However, any function that already uses the layer version continues to have access to it.
