JevMade field notes / Keel 0.2.0 architecture and source walkthrough

Give a coding assistant choices the application can check

Avid explains how Keel lets Jev or local Laya choose an available coding service or tool group without taking over every agent.

Our summary

A coding workspace needs to choose who handles a task and which tools are available next. Avid's Keel guide gives those choices narrow boundaries. The application prepares options it can run. A decision model selects one or declines to choose, and the application checks that the selection is still available before using it.

A new task can receive a suggested coding service and model unless the user already chose them. Running sessions stay unchanged. Inside Keel's built-in DeepSeek agent, four work stages allow different tools: inspect, implement, verify and answer. Outside agents control their own steps. Choosing a stage cannot bypass the application's normal permission checks.

Keel's reviewed build targets Apple Silicon Macs and uses local Laya unless hosted Jev is chosen. Its records preserve selections, answers rejected because options changed, and replacement choices. They support proposed comparisons, not automatic training or demonstrated coding gains. Faster judgments only help if the whole job, repeated attempts and review effort improve.

Key takeaways

  1. Offer only choices the application can actually run, then check them again before acting.
  2. Treat choosing a worker, limiting tools and granting permission as different responsibilities.
  3. Preserve failed decisions and compare reviewed changes on separate tasks; records alone are not self-improvement.

The guide describes a particular Keel 0.2.0 version; later versions may differ. Jev can select a prepared coding service and model, or judge whether such a choice applies. Those judgments cannot replace permissions or checks that the option is still available. Local Laya and hosted Jev process data in different places. The guide does not demonstrate improved coding results.
