The Ladder

The climb.

Five modules, five rungs. Each one wraps the bare model in another piece of the harness — from a sandbox with tool calls, up to a fully evaluated, secured, production system.

Module 01 → Module 05 · A harness, assembled one piece at a time
The climb · Five rungs 01 / 06
FLOOR · MODEL + TOOLS + SANDBOX TOP · FULL HARNESS 01 MODULE 01 The Bare Agent Model + tools + system prompt + a sandbox. The floor. 02 MODULE 02 Skills Procedural recipes, loaded by progressive disclosure. 03 MODULE 03 Domain Knowledge The hard-won expertise the model doesn't have on its own. 04 MODULE 04 Ops Layer Managed pipelines. The runtime substrate. 05 MODULE 05 Eval + Security Custom judges, production traces, the lethal trifecta cut.

The final state

Module 1 is a poltergeist.
Module 5 is the lamp.

Every rung adds another piece of the harness around the model — until the agent stops being a thing that haunts the system and starts being a thing the system contains.
