Instead of loading every tool upfront, your agent gets four meta-tools: search, inspect, call, list.
Progressive discovery. 50 tokens vs 18,000 for typical workflows.

Opus is a beast at planning (and coding) but I still have it spawn parallel subagents using Sonnet 4.5 when possible because Sonnet also ships code like a machine.
Save on those rate limits!

@Experian is impossible to reach when your account gets hacked. Their AI blocks you from any human help. Anyone dealt with this? WDYD?

anyone actually solved this or is everyone just vibing?

One thing I've noticed over this holiday break:
I've been rapidly prototyping ideas with AI, then taking a full day to sit with them and decide if they're actually worth pursuing.
And since the code is AI-generated, killing bad ideas feels completely painless.

Gemini 2.5 Flash is absurdly fast and honestly holds its own against the bigger Gemini models.. at least for UI/design work.

Day 2 of sharing my waitlist for my new iOS app https://www.trystay.app/
So far I posted on LinkedIn and pulled in 2k eyeballs. Only 23 signups, a 1% hit rate...not exactly going viral lol.
Curious which channels actually move the needle for fellow indie app builders
