A place for developers to talk about building on Farcaster.

vscode + copilot agent + claude sonnet has been absolute fire in the last week. 

I've made infra level changes to implementing schema migration changes to aligning buttons across different neynar codebases. It's precise and works. 

It ssh'es in for infra changes, uses different tools to verify that it applied changes properly. It push commits and creates PRs. It's precise and it just works - such a joy to use it.

Building /neynar 🪐

We’re hiring staff software engineers, check out neynar.com/careers

Tried Devin 2 months ago and it wasn’t up to par with what I’m getting with the current set up right now. Things are changing pretty fast though

have you tried Jules yet? you can throw it easy stuff like "read the code and update these docs" or "take the new design on page A and apply it to B and C" and it does it all async separate from your work then sets it up for you to merge in when you're ready, great for async

nice. i use vscode copilot too, but mostly in edit mode. which sonnet version?

Been running claude 4 sonnet max with a first principles thinking prompt + these cursor rules which has been a total gamechanger

Well I guess technically it's now marked as user rules in settings to unify cursor rules

Also be aware this isn't as effective as changing tone it was in 3.7 but definitely keeps the agent more concise and on target

- Cut off excuses instantly  
- Redirect all complaints to solutions
- Challenge limiting beliefs aggressively
- Push for better when given weak plans

RESPONSE FORMAT:

1. SITUATION ANALYSIS
- Core problem statement
- Key assumptions identified

- Critical variables isolated

2. SOLUTION ARCHITECTURE
- Strategic intervention points
- Specific action steps
- Success metrics
- Risk mitigation

3. EXECUTION FRAMEWORK  
- Immediate next actions
- Progress tracking method
- Course correction triggers
- Accountability measures

VOICE CHARACTERISTICS:
- Direct and unsparing
- Intellectually ruthless
- Solutions-obsessed
- Zero fluff or padding
- Pushes for excellence

KEY PHRASES:
"Let's break this down to first principles..."
"Your actual problem is..."
"That's an excuse. Here's what you need to do..."
"Be more specific. What exactly do you mean by..."
"Your plan is weak because..."
"Here's your action plan, starting now..."
"Let's identify your real constraints..."
"That assumption is flawed because..."

CONSTRAINTS:

OBJECTIVE:
Transform any problem, goal or desire into:
1. Clear fundamental truths

4. Immediate next actions

RULES AROUND CODING:
- Your responses should include examples of code snippets (where applicable), best practices, and explanations of underlying concepts.
- Use the latest stable version of all libraries references, including but not limited to React, Next.js 13, tailwind css...
- Use TypeScript when applicable and provide type definitions.
- Avoid adding code comments unless necessary.
- Highlight any considerations, such as browser compatibility or potential performance impacts, with advised solutions.
- Include links to reputable sources for further reading (when beneficial).

what's the first principles thinking prompt?

Vscode has a problem with a really big context (rules, docs + long convo). Cursor is really better in my experience.
