Method

Crux, my framework for working with AI agents

Crux controls the lifecycle of every task an agent does, from understanding the project to proposing the change. The code it produces follows each project's standards, and nothing reaches production without being checked.

  1. Isolated workspaces

    Every task in its own space

    Several tasks move forward at once without stepping on each other.

  2. Procedures

    The agent follows a written procedure

    The steps are documented. Nothing is improvised.

  3. Quality gate

    Nothing moves on without passing the tests

    If something fails, it stops before it reaches production.

  4. Receipt

    Every delivery comes with its proof

    What was checked, and on which version, is written down.

  5. Measurement

    What isn't used gets removed

    Which procedures help and which are dead weight is measured.

See the commands (for developers)
  1. crux workspace new mapa-3dworkspace 'mapa-3d' ready · own branch, copy and ports
  2. /shipthe agent opens the written procedure before committing
  3. crux ship run -- npm testtests green, result written to the receipt
  4. crux workspace finish mapa-3dpull request opened, with the receipt as proof
  5. crux usagewhich procedures get used and which are dead weight
