I'm building Little Worker, software for working with AI agents.

I make videos about the things I build and the questions I keep coming back to. I keep asking until I understand, and share what I learn.

Ship Log

4h since last ship
  • #3122feat(protocol): the OpenAPI description states what a dated version keeps stable
  • #3132test(core): run loop ceilings stop counting the breakage retry sweep as the turn's work
  • #3113test(repo): the Today desk proof step expects Available for a worker on no task
  • #3136docs(brand): sign-in logos are the shipped iPhone icon, Pip on sand
  • #3117refactor(protocol): a task's event routes move to their own group, with no wire change
  • #3121refactor(core): a task keeps only its chat, not a work conversation that always matched it
  • #3120feat(core): shared memories may share a name, and a note write leaves the memory's updated time alone
  • #3118fix(protocol): core's enroll answer names the workspace root the runner reports
  • #3115test(core): the MCP provider fixture stops answers in progress when it closes
  • #3116fix(ios): Today's give tip closes when a chat opens
  • #3112ci: closing or merging a pull request cancels its CI runs
  • #3111ci: Lint runs on every pull request, so a required Lint is never skipped
  • #3109ci(runners): the M1 takes CI jobs only when Parker says so
  • #3110chore(desktop): Mac app 1.0.0-rc.14
  • #3108fix(core): a failed task check is tried again in 2 seconds, not 30
  • #3078fix(console): the production check's person tools route and the proof launcher pass the lint guards
  • #3107fix(console-function): main's type-boundary and effect-style guards pass on the lock and live-progress tests
  • #3106test(core): run loop ceilings make room for the question wording and the alert-task statements
  • #3104fix(repo): the proof's model answers core's task check, so Done comes right after Allow
  • #3103fix(ci): the borrowed M3 turns its runners off every day at 07:45
