The built-in code-review workflow in Claude Code 2.1.220

1. Result

Claude Code 2.1.220 contains a built-in JavaScript workflow named code-review.

The program registers this workflow with hidden: true. The workflow is inside the installed executable. It is not the public Markdown code-review plugin.

The workflow has five stages:

Plan: Yabeda Monitoring System Adapter

Goal

Add an optional Yabeda adapter so that users who define metrics via Yabeda's DSL can have those metrics sent to CloudWatch through the existing Reporter infrastructure (async batching, StatisticSet aggregation, queue overflow protection, high-resolution support).

This gem does not collect metrics via Yabeda. The existing Puma/Sidekiq/Rack/ActiveJob

Worker TERM/restart benchmark (Docker + k6)

This benchmark reproduces the scenario discussed in chat:

4 Puma workers
open-model traffic at 12 req/s (k6 constant-arrival-rate)
synthetic Rack app with ~250ms service time
service alternates CPU and IO slices randomly every ~10ms
compare threads=5 vs threads=25
during traffic: kill one worker, wait for restart, let it serve ~5s, then kill a different worker (round-robin)

Unslopper local run notes

This repo is just a scratchpad for running the Unslopper model locally with llama.cpp.

What worked

Install llama.cpp via Homebrew.
Use the GGUF Q8_0 quant (the bf16 repo is too large for typical Mac memory).
Use llama-completion with a Qwen-style chat template prompt file and --no-conversation so it does a single completion and exits.
Redirect logs away from stdout so the output file is clean.
