spent a decade securing other people's code. now shipping my own. // @shipramen · envsafe · (ctf for ai slop)

[Chester Brian @chestrbrian]

spent a weekend vibe coding this:
a security CTF where every level is a startup someone one-shotted and shipped without reading

9 levels, 9 real vulns hiding in plain sight. find the flag, then read the exact AI convo that produced the bug

for vibe coders and the people who clean up after them 👇

@kunchenguid ok, maybe i’ll wait it out for a few days before having it work on my codebase

Fable 5 😳

[Chester Brian @chestrbrian]

we are going to need a higher mrr just to afford the api bills at this point

[shirish @shiri_shh]

Claude Fable 5 vs Opus 4.8

[Chester Brian @chestrbrian]

@ClaudeDevs you guys are amazing!

anthropic for months: "we need to run more safety evals"

claude mythos dropping today:

[Chester Brian @chestrbrian]

made a quick ctf based on the insecure ai slop code agents love to output.

it's been 5 days and 78 people are in but it’s incredibly lonely at the top.

if anthropic drops the public version of mythos tomorrow, someone please feed all 9 and post the logs in the replies. curious to see where the human vs agent baseline is actually at right now.

[Chester Brian @chestrbrian]

one guy just cracked L5 on our ctf.

watching the live logs is basically a masterclass in how people approach problem solving. nobody has cleared all 9 yet.

it is actually wild seeing how differently human brains approach ai generated logic flaws in real time.

[Chester Brian @chestrbrian]

@merts_dev respect. same tbh i try to build it right the first time but u never really know what is going to break until it breaks

[Chester Brian @chestrbrian]

the biggest bottleneck in vibe coding rn is having a computer science degree.

engineers will spend 4 days arguing with claude about software architecture.

non-tech guys just ask for a working product, ignore the impossible bias and actually launch it.

[Chester Brian @chestrbrian]

@merts_dev fair but how do u even measure that sweet spot when u still have zero users?

[Chester Brian @chestrbrian]

@619ssvignesh @district_india @bookmyshow this is cool bro. i might not watch but id still play with that app

[Chester Brian @chestrbrian]

anthropic is saying claude mythos is too dangerous to release.

the real threat is the vulnerable garbage that current agents write directly to prod.

built a CTF fail to show u exactly how fragile it is.

if u can't clear the tutorial levels, u are not ready for mythos anyway.

[Chester Brian @chestrbrian]

been on this app since 2018 just trolling and finally hit 100 followers today.

im a cybersecurity exec by day but trying to launch indie products at night is actually humbling.

ai can write your entire backend in a weekend but it cant build your distro.

was going to keep my new project stealth and charge for it but decided to just make it a free hub for builders instead.

what are u shipping this week? lets connect 🤝

[Chester Brian @chestrbrian]

been holding out on windsurf for all my builds.

but now that it is basically just devin desktop im actually open to switching.

cursor guys drop exactly one valid technical reason to migrate my repos that isnt just hype.

[Chester Brian @chestrbrian]

@TTrimoreau porkbun for me, not even close with those four

[Chester Brian @chestrbrian]

@alex_lrz_nmv just soft launched shipramen[.]io, and a few more on the pipeline 😅

[Chester Brian @chestrbrian]

any da nang builders on here?

landing next week 🛬 want to see what the local scene is building

[Chester Brian @chestrbrian]

@DevQueenHQ lets connect queen 🤝

[Chester Brian @chestrbrian]

@madsmadsdk i can relate 😅 i keep deleting that app from mywife's phone
