Enjoyed hosting an @aiforalllive meetup this evening at @tessl_io HQ. Thought provoking sessions from @anne_e_currie (fireside chat with @HannahFoxwell), and @Thomas_Essl.

[Simon Maple @sjmaple]

We've been busy here at @tessl_io, working on Spec-Driven Development. Some BIG news: We're announcing the release of two new products from Tessl https://t.co/k46SF4KoAp

The 𝐓𝐞𝐬𝐬𝐥 𝐅𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤: makes agents capture intent in specs before coding, aligning you and the agent on what to build. This truly keeps agents on the rails - It’s available in private beta - ask for access on the site: https://t.co/TmIfR7CtsK

The 𝐓𝐞𝐬𝐬𝐥 𝐒𝐩𝐞𝐜 𝐑𝐞𝐠𝐢𝐬𝐭𝐫𝐲: helps agents use open source better. A registry of over 10,000 usage specs that guide agents in application development. It’s in open beta and free to use - check it out: https://t.co/HzTezL6TaU

It's been such a fun journey already, just to get to beta, with the best team I've ever worked with. Super excited sharing our products with the community so we can build in the open!

Want to see it in action? Here's @bgalbs showing off the products!
