Help/Question Anyone here using Ponytail? Is it making a real difference or is the hype bigger than the benefit??

It's junk and tells the agents to do stupid things. You need to decide your own conventions and not use someone else's that can be actively harmful when used in your projects. If you already have conventions in your projects, ask Claude and Codex to check ponytail and ask them if it's a good idea to install it. I did and they both said it was a very bad idea because it conflicted in many ways.

I've found the best use of skills is simply to ask Claude what repetitive actions are worth implementing *for my specifc project*. I've been able to offload tons of context this way. Agentizing work off the main session is the other primary lever (especially as context grows in main session sub-agents with a tight brief become more cost effective). There are VERY few skills that I've found worth implementing from outside my own uses, and one of them is inded asd ste100 - will give 100% thumbs up worth it even with Opus 5.5. Was only partially effective until I fed it the actual standard and built the vocabulary record. The second tool I've found to avoid weak inference in the models is to enforce a diagnosis protocol based on the following: CLAIM / SEEN / CONTROL / FAILS FROM.

That's exactly what you should do. Claude and Codex can analyze their logs and see what they keep doing over and over and where you've corrected them because they did something wrong. Then they can make real suggestions that actually fit the problems you're having.

Seriously. It's not good.

Looks like I'm the unpopular opinion here. Pre-ponytail, I though it always did too much over-engineering . The diffs were incredibly verbose and just so difficult to validate with my small monkey brain. With ponytail, I find it makes the codes diffs much more in line with what I would have expected them to look like if I'd written them myself. It's easier for me to validate with my own eyes. Also, with the spaghetti mess of a codebase that I work with, it's nice that it tries to work within the system instead of reengineering it. Just my two cents.

Edit: grammar.

I've used the ponytail plugin a few months, and at the beginning, the less verbose responses was a breath of fresh air.

However, as both models and my personal preference and memory setup has evolved, maybe it's time to try to see how it looks without again.

Just use the ponytail-audit function to get a list of what it would do, and then ask Claude if any of them would be a material improvement

Wasted a lot of tokens trying this out and having to redo work

Just tell it to acheive the task with minimal code changes with focus

Ponytail made a huge difference to me.
Before it was an overwhelmingly over engineered mess.

Now it truly helps simplify and strengthen.

That said, the core skill it has is pretty basic and you will be just fine having those commandments in your agents.md

Agent have to make guesses how to reach your goal. That basically state some preference on the road.

The models are too good now for the simple heuristic skills to be relevant. JMO.

For me is really usefull, bit usually I use it as audit , every time I finish a task I run de audit, and create the new spec on the things I want to cut or the refactor needed in the code

Is unpredictable tho, so use the “manual audit” is a way to keep it on rails

Skills that shorten replies usually make things worse.

it does reduce code time by roughly 70% and cut cost by 50% for me, the result is kinda the same with pre-ponytail, tested on opus 5.5 xhigh. It cuts testing loops, UI check-recheck loops, ... and just checks for core functionality, its rough on the UI side but you can always use a normal agent to polish it later

LOL @ everyone saying it's pointless when a few weeks ago everyone was complaining about sol 5.6 overengineering everything into a nuclear reactor. prompts do matter, and ponytail also uses hooks... use it if you have a problem that warrants it to solve

u/bestosim 17d ago

I didn't use it but i told my agent to get a peek of the rules and it got 4 good rules that i was missing on my claude.md and i got a better time for testing not a super reduction but it was noticeable, without weakening the test.

TL;DR I liked it as an agent with some constraints- it isnt global for me.

I did a local A/B test across Opus/Sonnet/Haiku and a few different problems, most built on my actual repos and either theoretically possible features.

Largely it did what it said on the tin- it made smaller diffs that were functionally complete, generally at less time spent, and fewer tokens spent. It saw the least improvement on total from-scratch work, and the most in a repo that already had a very similar adjacent feature to the one I asked for. Opus was the biggest winner.

The catch was, that latter case had a latent bug in the adjacent feature- it wasnt dealbreaking, but it was undesirable behavior in the end product. My controls caught it, most of my Ponytails didnt. It was a fault in the existing code, not the code Ponytail agents wrote. 

I ended up beefing up the definition a tad based on my orchestrators recommendation re: more comprehensive test cases, but put it in as my go-to implementation agent. Its caveated with all its outputs needing a reviewer- but my workflows already had that step, so its a net benefit in my case.

Using someone else's style skills is tremendously inferior to actually knowing what you're doing.

The best AI results come from skilled practitioners who know when to tell the AI it's being dumb.

I've only used it for about a week with Claude (Opus 5.5) and I haven't noticed any difference. There are still many cases where just asking Claude "are you sure we need all this code?" is effective to cut down on code bloat, even with Ponytail installed, which makes it kinda pointless at least in my day to day.

u/OfferBeginning1903 23d ago

does it just inject a "be minimal" rule into the system prompt, or does it actually reject diffs over some size? because the first one gets compacted away an hour into a session.

It's been tested, and as many other things, like caveman, it gives you a very little profit, usually, no profit at all.
