seems like codex's multi-agent is not quite ready for prime time ๐Ÿง been hitting a bunch of issues mostly related to how the main agent and the subagents interact and their lifecycles

(using 5.4 xhigh)
(and yes well I guess it's to be expected, it's experimental for a reason ๐Ÿ™ƒ)

been catching up with the AI world and was reading Simon Willisonโ€™s Weblog - in particular his Agentic Engineering Patterns section: simonwillison.net/guides/agen...

decided to read through it and extract some improvements for to agentsparty.dev ... quite a beefy addition ๐Ÿฟ

ICYMI: I built a D&D-themed multi-agent orchestration framework and would love your help testing it ๐ŸŽฒ ๐Ÿ‘€

it's got DMs, adventuring parties, journals, and a "throne room" for meta-orchestration (and its OSS)

[bun, preact, astro + gemini 3.1]

no shade on anyone but damn if you are doing agentic coding for webapps and you are not using the chrome-devtools MCP... why
it's such a massively useful tool

here's where I could use help: I've got limited agent availability on my machine, so I haven't tested this across different tools yet

if you're using Cloud, Codex, or others - try it out? each has its own quirks with subagents

and OFC it's fully open source: github.com/kelset/agen...

very much a personal time project and not in its final form, but I think there's something here worth exploring

used it as an excuse to experiment with Gemini 3 (and when I could, 3.1 pro preview) plus try out bun, preact, and astro

the site's pretty simple - configure your setup, click a button, get a zip file, tweak it locally however you want

THEN at some point I was like: I want people to play with this, especially folks new to multi-agent stuff

could've made it a giant gist... buuuuuuuuut then I built a website instead ๐Ÿ™ˆ๐Ÿ™ˆ๐Ÿ™ˆ๐Ÿ™ˆ๐Ÿ™ˆ

ran into the classic problem: sub-agents need to communicate but there are limitations

solution? journals. the party has a journal, the game master has a journal, they coordinate through them

kept iterating, added personalities, even built a "throne room" meta-level ๐Ÿ‘€

recently I tried multi-agent stuff hands-on and realized itโ€™s basically d&d: you've got a game master (main agent) directing a party of sub-agents, each with their own special abilities to tackle tasks

naturally, I leaned into the theme hard and built the whole thing like so ๐Ÿง™โ€โ™‚๏ธ

soooOOOO I've been nerding out on multi-agent orchestration lately and ended up building something silly that I kinda want to share ๐ŸŽฒ๐Ÿค“

โ€˜The most bitter newsโ€™: Iran reels as more than 100 children reportedly killed in school bombing The building appears to be among many devastated in Trumpโ€™s โ€˜major combat operationsโ€™ as long expected attacks arrive

Regardless of your political positions, if you are not disgusted by the US and Israel bombing a school you should prob do a morality check.

(yes, yes, we know that based on Israeli intelligence there were terrorists and nuclear weapons in the basement...)

big step recently: after 8+ years, I finished my therapy journey with my main therapist. It has run its course, and made me a much better human ๐Ÿง˜

it doesn't mean ofc that I'm perfect, but that the type of work i could do with them is... dealt with, for now.
Next up? CBT ๐Ÿฟ

the most sustainable career advice i ever got: treat your energy like a finite resource, because it is ๐Ÿ”‹

uhm i feel i lost complete touch lately with the London tech scene. what meetups are folks going to these days? or are we past that, and now there are other ways/places devs people to nerd out about stuff?

greenfield PSA: you don't need to maintain a huge project to "be an OSS person" - helping triage issues, reviewing PRs, answering questions in discussions... all of this keeps projects alive ๐ŸŒฑ๐Ÿค

kind of bummed that codex still doesn't support subagents/agent team but happily surprised to find that gemini does have them ๐Ÿ‘€๐Ÿ‘€๐Ÿ‘€
