Our recipe cards need ink line-art, not photography. Bedrock does it at ~$0.04/image; our RX 6700 XT does it for $0. The ComfyUI API is three HTTP calls, the node graph is seven nodes, and tuning taught us that color and sparsity are coupled variables.

not nova act
Amazon Nova Act is going away. We rebuilt everything it does as a local-first stack: Playwright hands, qwen3-vl planning, CLIP grounding assist, and a 9-tool MCP server. How it works, the network topology, the code, and the screenshots proving it.
Local-First Deploy: Retiring CodeBuild for a One-Minute Ship
The bryanchasko.com site is done with managed CI. GitHub Actions, then self-hosted Woodpecker, then AWS CodeBuild — all three put a five-minute remote round-trip between a change and seeing it live. The replacement is one local script that ships in under a minute.
herald-valkey: A Self-Hosted Memory Store on a t4g.nano, Not a Managed Cache
Why the haunting runs Valkey on a single always-on t4g.nano at ~$3.71/mo instead of Amazon ElastiCache Serverless — the private-vpc backbone that underpins the bench platform and cross-agent MCP coordination.
From Hallucinated APIs to Shippable Banners: Adobe Express MCP Lab + Cloud Del Norte Builder Banner
A lab that stops LLMs hallucinating Adobe Express add-on APIs — 5 agents, grounded docs + types, and a real 1440×400 AWS Builder Center banner for Cloud Del Norte built via the MCP, from challenge to shippable PNG.
Muse Glimmer on HeraldStack: Local 30B Agents, One GPU, No Cloud
How we hooked Meta’s Muse Glimmer 30B into a local agent fleet on a single RX 6700 XT — on-demand llama.cpp, Valkey gpu_lock, Ollama, ComfyUI, and a Firecracker microVM that delegates from Spark to Glimmer.
Moodle Course Builder: CI Pipeline, Nova Act Regression, and Kiro Orchestration
A Chrome MV3 extension that builds entire Moodle courses from CSV files — tested end-to-end by Amazon Nova Act driving a real browser through the full upload-confirm-build flow, all orchestrated by Kiro CLI agents.
Self-Hosted CI with Woodpecker: The HeraldStack Pipeline
Running 35 repos through a self-hosted Woodpecker CI instance on a single AMD workstation — zero vendor lock-in, full control, no per-minute billing.
