README claims ↔ code3

free

gstack is how I do it. It turns Claude Code into a virtual engineering team — a CEO who rethinks the product, an eng manager who locks architecture, a designe README.md:23

Fork it. Improve it. Make it yours. And if you want to hate on free open source software — you're welcome to, but I'd rather you just try it first. README.md:27

The README states it is free, but the code requires paid OpenAI calls for text, image, and speech-related features. design/src/check.ts:37

local

Step 1: Install on your machine README.md:51

Prompt injection defense. Hostile web pages try to hijack your sidebar agent. gstack ships a layered defense: content filters (datamarking, hidden-element strip README.md:461

The README states it runs locally, but the code requires calls to OpenAI (api.openai.com) for text, image, and speech-related features. design/src/check.ts:37

offline

/make-pdf Publisher Markdown in, publication-quality document out. Mermaid and excalidraw fences render as vector diagrams, fully offline. Images scale to the p README.md:284

gstack-context-bill Token bill-of-materials — read-only, offline audit of what an installed skills tree costs in tokens: always-on frontmatter every session p README.md:368

The README states it works offline, but the code requires calls to OpenAI (api.openai.com) for text, image, and speech-related features. design/src/check.ts:37
