    By far one of the most common questions about @lightsprintai is how merge conflicts are handled at scale.

    By far one of the most common questions about @lightsprintai is how merge conflicts are handled at scale. We thought so too! But counterintuitively, the agent actually is able to handle it easily. thats because it can easily figure out with the context of both authors!

    For our first event on Tech+65 next week - a live AMA with Victor Neo, who I reconnected with recently after nearly a decade. It’s not everyday that you get to talk to the very first employee of a company that has spawned a new Singlish verb “to Carousell" (ie to sell an item online), and a new local stereotype ‘Carousell husbands’ (awkward grown men instructed by their wives to wait furtively at train stations to sell/buy an item of unknown origin - usually collects item in bag, does not bother to check, leaves after a curt nod of acknowledgement).

    Skills matter when they package judgment, not just prompts.

    Exactly. Skills matter when they package judgment, not just prompts. Models change quickly; good ways of scoping, reviewing, debugging and verifying change much more slowly. Skills are how those practices become portable.

    This is the benchmark shift that matters: test agents on your own work.

    This is the benchmark shift that matters: test agents on your own work. Public scores miss task mix, cost, latency, reviewer corrections and whether the output survives merge. Internal evals are becoming company infrastructure.
