thousands of CVEs impacting the latest Debian kernel release but they're not all actually CVEs. confused? so is everybody else. that's what happens when you abuse the social contract.

the Luna time per task range is most realistic I've seen. totally can confirm by using it a lot. it often takes such a long time completing a task because I just fire it off on max all the time btw awesome work by Theo on building slopalytics (slopalytics.com)

I left Opus 5.5 Max with a goal and after 2 hours it's still figuring this out Is there a name to this type of anxiety that you're not entirely sure what and how the yield on an AI prompt is going to end up like...?

ahh yes one of those days doing deep work but this is on me, need to push it upstream also because in the future remote workloads (in compute and environments you host elsewhere) will be treated as ephemeral states

things you see when you build benchmark projects... out of the VulnBench 2.0 security eval execution logs, sometimes you pay $85 for just 20% recall (and 1% precision), and other times you pay $23 for total 0% reported findings

mind blowing how the variance of different fixtures in the Snyk VulnBench 2.0 benchmark data shows up for the same security agent harness, and same model (OpenAI's GPT-5.6 Sol) all the data is open on vulnbench.com

as I was wrapping up the Snyk VulnBench 2.0 publication, here's a quick glimpse into the various security agents and their cost to run the evals codex security agent, claude code security review and vercel's deepsec all completed and heads up, costs do not correlate with findings accuracy :)

Great episode from Gergely Orosz interviewing Matt Pocock and touching on topics I really like around developer education, course building, the right focus in times of AI. The podcast goes into other software engineering depths and the grill-me skill but more than anything else if you're in DevRel

to whomever needs to hear this, all of you folks automating GTM, outreach, marketing and growth with AI agents - if I see an unsolicited mail in my inbox that is AI generated and 100% of them are, I am immediately pushing the "Spam & block" button. I've already done this maybe like 20-30 times in

whoever you are at apple who decided that the default Finder folder is "Recent" and not "Downloads" you should resign immediately as a public service to humanity, go to Finder -> Settings and change it so that you get back 5 minutes each year

btw hope you know that Snyk always had a pretty generous free tier for dependency scanning, code security, and other capabilities we're extending that into credits based consumption for Enterprise too

hmmm, didn't Anthropic folks say that this model switch in between session is no longer an issue or did I miss something? that's from the Claude Code app

have you heard of Jev from TypeSafe AI by now? super fun infra to build with for doing agentic work but, it's also extremely handy on its own merit of classification and labeling I created a CLI tool that downloads all songs for any given artist and then classifies the lyrics across theme, mood,
using jev from TypeSafe AI to classify song lyrics for their mood, complexity, 1st person, overall theme and such

the first rule of the new npm is that the first version is always excluded of build provenance
010
Liran Tal @lirantal.com · 22/09/2026
the npm registry now performs some level of package validation and evaluation before pushing the latest tag to the latest version published I'm not entirely versed on how deep and thorough the security audit here but better than nothing...

so I guess this is the new default for agent coded CLIs these past 6 months huh

have you ever wondered what'w the mood of one of Madonna's song? well, now you can, with Jev from TypeSafe AI I used Jev to classify any artist (all their songs / discography) and now we get labels for mood, lyrical complexity, overall theme and some other stats this has been very fun building

looks like varlock implemented a bunch of DX improvements around env secrets, very smooth and helpful nice work Theo Ephraim and varlock team

is the env vars secrets space heating up finally?? varlock vs infisical

new academic paper (Politecnico di Torino, arXiv) just benchmarked the whole field of agent-skill security scanners against real skills.sh skills Snyk Agent Scan is one of only 3 scanners integrated into skills.sh's own audit pipeline (alongside Socket + Gen Agent Trust Hub) — and had the broadest

To everyone who attended my talk today at #AGNTCon + #MCPCon Europe in Amsterdam (yay, windmills!) - I uploaded my deck as a PDF to the session on sched, so you're welcome to browse through and re-visit the topics Should be freely available to everyone else too:

wrote a book on this 2 years ago maybe you want to read or give it to your agent

lol, if only it was that easy, right or... maybe it is? 😯 ask me :)

reminder to use the boxdown CLI to configure your ChatGPT Codex or Claude Code to use local isolated container environments for agentic work (magically sets everythig up for ya!) yes, it's open source 🎉 p.s. Cursor is supported too if you're a fan of it

Snyk VulnBench headline numbers How well do other models compare with an F1 agreement score with Snyk Code security findings from a SAST scan and their error rate (Opus 4.7 Max was surprising!)

Liran Tal @lirantal.com · 16/09/2026
geeky but the terminal is back and I was having fun building up the Snyk VulnBench harness for benchmark purposes (now prefer the open source Harbor framework / CLI) learned so much from building the harness though totally recommend

Liran Tal @lirantal.com · 16/09/2026
early back in May when I ran the Snyk VulnBench benchmark I compared various models to a Snyk F1 reference score (can they match what Snyk Code is reporting as security vulnerabilities) here's what they reported bonus: error bars

wip for running the benchmarks on VulnBench 2.0 which is a new set of fixture data, larger apps codebase, varied language ecosystem... pretty interesting how harness + model are very much a pair, for example Codex Security agent with Terra on xhigh just isn't scoring high enough

do we have this chart with updated models? would appreciate if someone has the prompt injection resistance from model cards handy to share
