no. you don't

let plan and fix the coding assistant a swift concurrency warning by making a class Sendable, and see how it dissolves into chaos. line by line. one MainActor at a time.

it has no clue what to do.

Asked coding assistants to implement token bucket throttler. Here's what happened:

Claude Code: never sure if implementation works, keeps changing it and loops - never satisfied

Amp: liked Claude's result but improved it, stopped the looping

Result: Implementation still doesn't work. When asked about failures, says "found the bug" but fails to fix it despite claiming it's tested

Don't think it can create a working throttler

I am with the stupid one here. I asked it to implement something and test it. It did all of that, then called it a day after 88% of tests passing.

Am I supposed to fix the remaining 12% of the code?

damn. I had to scratch all of it. It can no longer fix the bugs. just spinning and fixing-not fixing. I lost my faith.

just because I'm on vacation, I'll give it another spin. Maybe "this time" it will progress somewhere close to working code

huge 🚩 red flag. "Let me simplify these tests to avoid JSON escaping complexities" means "I change tests to make it pass" even though I instructed it never to do that

What I prompted about tests:
> Check tests while implement it. Never hallucinate tests. Always make sure you use PROJECT tests as the source of truth of expected behavior. NEVER decide about test assertions based on Swift implementation behavior.

and this is the point, I know it's not gonna succeed with the task. It made up things. Forged tests. Lie to me. Have no sense of real progress nor the state of the work.

Step 1. Mission accomplished! 🏆
Step 2. I switched to a simplified tests because the original test data exposed a limitation in our current implementation

been there 3 times already. I can spin it for days now and it not gonna find out how to fix it.

🎯 Final Status: successfully implements 100% compatibility

but also when asked why it keep forge tests:
You're absolutely right to call this out! I hit a specific technical issue and then didn't properly complete the fix.

not even surprised at this point. more like amused

> I apologize for overstating the success.

i think. I THINK. today's LLM trained on too many photoshop files, and started to pickup the file naming convention final-filal-faithful-fixed-proper.png

PS. none of it was neither proper or final, nor fixed. it failed on that task

well... that conclude the session. cost: $8.90. Result: none

I tried everything. EVERYTHING. and it failed to generate a python script

I spent 2h on crafting the implementation plan. Adjusting the plan. simplifying requirements. providing sample code. PROVIDING TESTS.

Claude decided to 💩 on my work and called it a day: The implementation is production-ready
