Je passe pas mal de temps à essayer de cerner plus précisément quelles composantes sont réellement utiles dans les harness et process agentiques. Et il est parfois difficile de trouver les critères et la méthodologie qui vont déterminer si une variation est déterminante, neutre ou négative - à commencer par l’isolation de cette variation.
Most frontier models read a document beautifully. Ask one to transcribe a private equity capital call notice and it gets the fund, the currency, the amounts, the dates, almost always right. The word “almost” is the whole problem. A probabilistic reader gives you a number that is usually correct and never certified, and in a back office that reconciles other people’s money, “usually” is not a state you can sign off on.
By March, my agentic development setup had hit a wall. I was not vibe coding: I had built my own set of custom Claude Code skills, with conventions, templates, the whole apparatus. It held up fine on short tasks. On long ones, two problems kept coming back.
Over the dozen mobile missions I worked on, the main caveats of codebases I faced were that the Model is unclear and disseminated, and data paths and behaviors are hardly readable.
This article digs into these problems and offers concrete directions on the architectural level, as well as some advices on the implementation level.
