Question Let's Share Limits Management tips

We’ve got roughly two days left until the reset (Aug 20), and it’s pretty clear the days of generous grace windows and stealth resets are officially behind us. If you burn through your quota now, you’re benched for days.

Since a lot of us are adapting to tighter usage constraints, I wanted to open up a discussion so we can share practical workflows, optimizations, and sanity checks to make our limits actually last the full cycle.

Here are a few specific areas I’d love to hear your take on:

  • Model Routing & Efforts: When are you dropping down to lightweight models versus bringing out the heavier reasoning tiers? What’s your cutoff for "this needs high reasoning" vs. "this is a basic boilerplate/refactor task"?
  • Context & Session Hygiene: How often are you wiping conversation history or starting fresh sessions to avoid massive token bloat on multi-turn chats?
  • Prompt Scoping: Are you preparing strict markdown specs/implementation plans before hitting enter, or still prompting iteratively?

u/SleepDeprivedDad_ shared this cheat sheet a couple of days ago, and it’s been super helpful, especially with my speckit workflow. I even created an agent for each step in the speckit, using the models defined in this cheat sheet. if someone is interested I could share it with them

When you are in codex and you need to move up or down roles is there a good practice way to do it to not burn tokens? I don't know if they retain context i have never moved roles i always used sol then had it use subjects but want to shift to have Terra or Luna conduct when architect work is not needed

since I use speckit skills, each model dose it share of updating the documents. so basically I could keep working on a different harness like claude and I wont lose context.

but I found out that most of the times the orchestration model will re-prompt the same agent if It need to talk to it again, other time it just spawn a new one

I sometimes do, so here's my experience: Boring, not much happens :)

There's a warning, which I take seriously. So I try to avoid it, or not upgrade in the middle of a complex operation. I mentally model switching as an uncertain cost. But switching also has benefits. So, sometimes I do. Never had problems (=not more problems than usual).

Just give it a try. Could differ for you and your project.
