# Comet Phase 2: Design

On first entering a phase, handing off to a new Agent, or restoring context, read and follow [Task Context and Artifact Language](../comet-classic/reference/scripts.md#task-context-and-artifact-language). Prefer the current continuation or claimed Action's `contextRequest`; do not retrieve repeatedly during uninterrupted work in the same phase.

After the entry returns layout, use `comet-classic/reference/classic-layout.md` to resolve each logical root. Reuse this protocol if it is already in context. Route all OpenSpec CLI calls through the adapter and use the bound `<classic-*>` roots for file paths; do not run an extra root show first.

## SDK Run path

On first entering the current SDK phase, handing off to a new Agent, or restoring context, read [phase entry and recovery](../comet-classic/reference/sdk-methods.md#phase-entry-and-recovery) and the current phase's section in that reference. Reuse them when already available and still valid in this session. Continue with the phase below; recovery routes based on `nextAction.kind` apply only to older responses without a continuation mode.
