How Jevie improves itself

Jevie gets better on its own: it audits its record, studies what you bookmark, proposes improvements as cards, and keeps only what proves better, with you deciding.

Use it

• improve jevieThe next audit of its own record, and your bookmarks once a day
• study https://x.com/…A post, a GitHub repo, a paper or a downloaded .dmg, compared with Jevie
• improvement cardsWhat it proposes: ideas first, then fixes by area
• card ab69366dOne card: where it came from, what it changes, the test that judges it
• build card ab69366dBuilt in a separate copy, never your working one
• judge card ab69366dMeasured against the current Jevie
• merge card ab69366d nowPut into Jevie, your call
• dismiss card ab69366dNot this one
• improvement sourcesWhere cards come from, and how each source did
• let small improvements build themselvesSmall cards built and judged without asking, never merged
• node jevie/improve/direction.mjsWhere you are taking Jevie, and --ideas for what to build next
• node jevie/improve/invent.mjsNew ideas, not fixes, each with its benefit and abuse case

How it works

Jevie keeps auditing its own record (requests said twice, slow answers, errors, its look and feel) and studies what you bookmark and what is new. Each finding becomes a card that names the test that will judge it, is built in its own copy of the code, and is kept only if it is clearly better, no slower and breaks nothing. Computer and browser use measure themselves the same way on real errands.

Once a day it also reads where you are taking Jevie and proposes a few ideas, and everything kept or turned down teaches it what is worth proposing.

Limits

• Merging is always yours; nothing reaches your Jevie without your word.
• A card beats the current Jevie on its test, which is not the same as you feeling it.
• About one in three daily ideas matches what you build within two weeks.
• Links to work sites, or hosts in ~/.jevie/self/work.md, are never read in.

Where it's kept

~/.jevie/improve/: cards, results, studies, direction and ideas; a card's code on its own branch in ~/.jevie/worktrees.
