I tried to make sense of "spec-driven development" by looking at 3 tools: Amazon's Kiro, GitHub's spec-kit, and the Tessl Framework

By spec driven you mean Sdd with Markdown or something like a lean prover alongside the project?

At the top of the "are doomed to repeat it" category is the notion of "spec-driven development" (SDD).

Using spec driven stuff works very well yes. It has spec driven design systems in crosslink for example. Like it has its own spec templates.

This of course relies on a heavily spec-driven codebase, which does seem to work

“spec driven development is broken…a spec isn’t just a more detailed prompt.”

“spec driven development is broken…a spec isn’t just a more detailed prompt.”
Spec-driven development is extremely useful, and that's what planning is done properly. Although, at least for now, plans have to be relatively small and digestible.
The problem with specs-as-source is that if the spec was sufficiently complete it would (almost) be the source code itself.

Loving these posts saying "Spec-driven development? That's what us managers have been doing for years!"
As any developer will tell you, the average spec isn't worth the Jira it's printed on.

Great tips about spec driven development with coding agents
- I use MUST / SHOULD format. I find it helps both me and the model
- Circle back frequently to have the model keep SPEC.md in sync
- It reaches a point pretty quickly where I no longer read the spec
- much as in my real job
- just kidding?

This is exactly where Tesla Autopilot/FSD is stuck: its "final spec" is a (deeply flawed) statistical average for human-driven crashes/mile that has zero relationship to the line it needs to cross to provide real value: the ability to be insurable and defensible enough for Tesla to assume liability.

Really looking forward to speaking at #MomentumDev in Cincy on October 15, alongside Sarah "Sadukie" Dutkiewicz, @tdesseyn.bsky.social, @guy.dev, @thesoccerdev.bsky.social, @chrisdemars.net, and a host of other amazing peeps.

People talk about spec-driven design, but the best spec you can have is a test—a test you write before you write the code. You don't write a test to see if the code adheres to a spec. The test IS the spec.
Don't write specs. Write tests.

AI, like any market spec driven horseshit, relies so heavily on preying on total ignorance. If I need a placeholder texture I can take a picture with my phone and it won't look like a piece of shit dipped in atmospheric lighting that I'll just have to make a press release about later. And it's free!

"If we just design the entire feature and what it has to do up front with extremely detailed breakdowns then feed individual stories into the AI one at a time you basically have AI driven development!"

"No this is completely different, it's agile with spec kit!"

I'm thrilled to join Haven Spec as Poetry Editor! Excited to dig into the beautiful mountain of spec poetry - the vivid, the emotional, the lyrical, the strange, the dark, the climate-conscious, the bittersweet, the idea-driven, the magical, the otherwordly, the weird. . . and everything else!
We're over the moon to announce that Jessica Peter / @jessicapeter.bsky.social has joined us as our new Poetry Editor!

i’m not actually sure this is true. Meaning that spec-driven dev & formal methods haven’t been picked up and there’s probably a reason for it
mainly: it’s cheaper & easier to use the code as the single source of truth rather than let specs & proofs diverge from the code
