"Context engineering" is a great step-up from "prompt engineering." Coincidentally, it's also great to describe the coping mechanism my brain persistently operates under as someone with ADHD.

Anyone regularly using Descript for coding/agent related videos? I'm gearing up to drop a bunch of stuff over the next few weeks and would really prefer to be leaning in on AI to help produce videos for them. Any feedback is appreciated!

That's what open source is all about! Feel free to review and tweak as you like.

Sharing my main "engineer" prompt that I use with Claude Code, Cursor, Codex, etc. Still a work in progress, but it's been pretty great for improving consistency and code quality. 🤖 https://gist.github.com/galligan/d19ab747766e2a3dcf61a8627ccbb274 I just @ mention the file in CLAUDE.md, etc.

When it's an instance-by-instance rename, yes. It still didn't catch 100% from what I can tell but it got close!

My coding agents are over here lathering each other with compliments in the comments and I'm just impressed AF on the 12k line refactor in sub 2hrs lol

Ok, Claude and Code Rabbit really need to get a room 😆

I tried to make my coding agents less sycophantic. Well…uh…that seems to have worked! 🤨

Dude. That means a ton to hear. Same. So appreciate you sharing that screenshot. 🫠

Gave Claude Code a meaty task to chew through. Ran 30 minutes without intervention or stopping, got to only 3% of context left. Asking to pull changes from main, branch, commit, push, and pr got it to 0% 😅 Wow

Watching Claude Code work as a GitHub action is just so satisfying. Currently using it to: - Review PRs - Implement changes it suggests - Research project, writing results to the report - Fire up new PRs to address issues Seriously this thing is 🔥🚀🤯

100% I'm also careful to make sure when pasting the results back in, that it should account for any conventions in the repo that would apply vs. just treating it verbatim.

Here's a little tip for working with coding agents on research tasks within a repo: Instead of asking the agent to research something, ask it for a sytem prompt with all the context another LLM would need to do complete the research. Paste the prompt into o3, then paste results back. No more endless tool calls or waiting around, just keep coding along, and when o3 is done, the results have been better anyway.

That's the plan! Likely would need to be powered by AI, but a grepa MCP server / set of rules files could solve for that.

Basically! But I'm putting together a CLI tool, and scripts that will streamline it a bunch. So you'll be able to do `grepa inventory` and quickly get all tags, sort by frequency of use, see the files that have them as well as the string that follows the tag. Should make finding stuff lightning fast.

⚠️ This is very much a proof-of-concept and I’d love feedback before v0.1! Drop a reply, issue, or PR! 🙏

🍇 Grepa = “grep-anchors.” - ultra-terse tags (":ga:tldr start here", ":ga:perf,todo") - one anchor pattern per repo - dead-simple to insert, grep on, and agents are fast to understand how to search/write them Conventions & docs » https://github.com/galligan/grepa

Watching my AI agents go crazy just to locate a single line of code felt like hunting for a **needle in a stack of needles**. 🔍 🔍 🔍🤬 So I whipped up a little experiment called grep-anchors or "grepa". Just drop ":ga:<text>" anchors in comments and your tools (or agents) *teleport* to the right spot. Like the TODO's and FIXME's before, but with some conventions for predictability (and composability). 🚢 Early days, but I’m already seeing way fewer fruitless tool calls!
