The previous post covered how we structured the codebase: Effect conventions, ast-grep enforcement, Drift, and CLAUDE.md to collaborate with Claude Code. You describe what you want, review the output, iterate. That works well. This post is about what happens when you step away entirely: giving the agent a list of issues and letting it work through them while you do something else. In autonomous mode, there's no... - Source: dev.to / about 2 months ago

We use ast-grep as a structural syntax scanner that operates on the syntax tree of code (using tree-sitter under the hood). You define patterns in a YAML file, and it matches those patterns against the codebase. Critically, it’s run as part of the CI pipeline and configured to exit with an error when a banned pattern is found. And they have to be errors, not warnings. We learned this the hard way. Warnings get... - Source: dev.to / 2 months ago

I linked this elsewhere but, the agent could have a skill to use https://ast-grep.github.io/ to perform such mechanical code changes. - Source: Hacker News / 3 months ago

The proper tool for this is ast-grep (sg) https://ast-grep.github.io/ And an agent can learn to use sg with a skill too. (Or they can use sed) The issue is, at every point you do a replace, you need to verify if it was the right thing to do or if it was a false positive. If you are doing this manually, there's the time to craft the sed or sg query, then for each replacement you need to check it. If there are... - Source: Hacker News / 3 months ago

We use https://ast-grep.github.io (on a pre-commit hook). Bridges the linter gaps nicely. - Source: Hacker News / 4 months ago

GStack is Garry Tan's Claude Code setup, and at nearly 110,000 stars it is one of the most popular skill collections out there. Instead of one mode that handles everything, it gives the agent distinct roles, each behind its own slash command. It has product vision, designer, engineering manager, release manager, doc engineer, QA, and post-launch retrospective. It is the same genre as Superpowers, a full workflow,... - Source: dev.to / 21 days ago

That is the design. And it is why GStack — Garry Tan's open-source Claude Code skill setup — has accumulated 82,700 stars and 12,000 forks on GitHub since its March 2026 launch. - Source: dev.to / 2 months ago

This is not the first time. Tan's previous project, gstack, has amassed over 69,000 GitHub stars. Developer Mo Bitar described it as "a bunch of prompts in a folder." Another founder noted that without the YC title, it would not have made Product Hunt. A developer who examined Tan's AI-generated website code found 78,400 lines including empty CSS files, duplicate assets, and test files shipped to production. - Source: dev.to / 3 months ago

And I believe any builder should use Gstack from Garry Tan. Old news I know, but for people who live under a rock like I do. - Source: dev.to / 3 months ago
