@kmcquade3 I went back to 4.7 because of this exact problem. Sigh

[Jon Zeolla @JonZeolla]

😱

[𝖊𝖛𝖆𝖉𝖊 @encrypted]

wait... you did what?!

[Jon Zeolla @JonZeolla]

@DerekFeehrer I dig it. Gonna give it a shot today

[Jon Zeolla @JonZeolla]

@HackingDave Now that's how you do a science fair project, ask the director of the FBI for help 💪

[Jon Zeolla @JonZeolla]

@HackingDave @simplylurking2 Have you tried tool hooks instead of prompt hooks? Much more reliable for restrictions

[Jon Zeolla @JonZeolla]

@unclebobmartin Exactly why custom linter rules, pre commit hooks, runtime monitoring, automated tests (perf, unit, integration, ...), static analysis, agentic review, CODEOWNERS, type checking, .... are all so critical

And even more important is maintaining and customizing to keep principled

[Jon Zeolla @JonZeolla]

@icanvardar @kmcquade3 I feel seen

[Jon Zeolla @JonZeolla]

@OpenAINewsroom @evanyou @astral_sh Incredible news congratulations @charliermarsh and team you absolutely deserve it.

[Lydia Hallie ✨ @lydiahallie]

if your skill depends on dynamic content, you can embed !`command` in your SKILL.md to inject shell output directly into the prompt

Claude Code runs it when the skill is invoked and swaps the placeholder inline, the model only sees the result!

@HackingDave The closest thing I've considered is using AI to do my travel research for work. Find a good gym nearby with evidence I can actually get a good workout there. Flights that meet some event specific criteria. Etc.

[Jon Zeolla @JonZeolla]

@HackingDave I'm in the same boat. I use AI for everything work related but for personal I haven't found a great fit yet

I'm doing perfectly fine with an ad hoc cowork or chatgpt to help plan a vacation or something. I don't need a 24/7 agent available via signal.... Yet at least

[Jon Zeolla @JonZeolla]

Code may be free but outages sure aren't

Some form of guardrails are more important now than ever

[SPEC @___4o____]

OAI and Claude both dropped to 98% uptime during February.

Another data point:
Github has had more outages in Q1 2026 than the entirety of 2016-2019, according to their status page.

Software is objectively getting worse.

[Jon Zeolla @JonZeolla]

@koylanai Gathering telemetry with hooks is 🔥 especially if you run parallel agents. Measure and identity anti patterns to improve requirements

It's also great for running deterministic guardrails or agentic reviews/quality gates

I've been addicted to hooks since CC first shipped em 🫶

[Jon Zeolla @JonZeolla]

Holy shit. What a mess, and happens all the time without being transparent enough to blog about it. Kudos @Al_Grigor

Guardrails for AI can help, but even they aren't perfect

The most important thing is to do something about it, now. And then improve what you're doing over time.

[Alexey Grigorev @Al_Grigor]

Claude Code wiped our production database with a Terraform command.

It took down the DataTalksClub course platform and 2.5 years of submissions: homework, projects, and leaderboards.

Automated snapshots were gone too.

In the newsletter, I wrote the full timeline + what I changed so this doesn't happen again.

If you use Terraform (or let agents touch infra), this is a good story for you to read.

@HackingDave Isn't it crazy? I have never made a real UI in my life before Claude (not counting geocities 😅) and now I swear I rip 20k loc of frontend every week

[Jon Zeolla @JonZeolla]

Mark your calendars, @manicode and I are gonna be hosting an AI coding nerdery conversation on March 18th

See you there 🚀

[Jon Zeolla @JonZeolla]

@dani_avila7 You can do similar without the third party dep with a bash function like this

2026, the year where you easily burn through the 50,000 minutes GitHub Enterprise gives you on a project with just two people

[Jon Zeolla @JonZeolla]

Is it a legitimate business expense to buy all of the Mad Max movies so I can understand all the gastown references?
