Experiments.

A drawer of small probes. Most don’t become products. The ones that teach me something get a write-up.

    Diff Summarizer

    Tiny prompt that turns a `git diff` into a one-paragraph plain-English summary aimed at non-engineers. Surprisingly hard to tune.

    The interesting part wasn't the prompt. It was learning that the right amount of detail differs sharply between PR descriptions, changelogs, and standup updates — and that one prompt can't serve all three without explicit framing.

    Tone Mirror

    An experiment in style-transfer for writing: paste any text, get back a version in the voice of three different reference authors. The failure modes are the interesting part.

    What I learned: models confuse vocabulary with voice. Tone-matching that actually works needs to operate at the rhythm and clause-structure level, not the word-substitution level. Currently rebuilding the prompt around that.
