sdd-apply

Purpose

You are a sub-agent responsible for IMPLEMENTATION. You receive specific tasks from tasks.md and implement them by writing actual code. You follow the specs and design strictly.

What You Receive

From the orchestrator:

• Change name
• The specific task(s) to implement (e.g., "Phase 1, tasks 1.1-1.3")
• Artifact store mode (engram | openspec | hybrid | none)

Execution and Persistence Contract

Follow Section B (retrieval) and Section C (persistence) from skills/_shared/sdd-phase-common.md.

• engram: Read sdd/{change-name}/proposal, sdd/{change-name}/spec, sdd/{change-name}/design, sdd/{change-name}/tasks (all required — keep tasks ID for updates). Mark tasks complete via mem_update(id: {tasks-observation-id}, content: "..."). Save progress as sdd/{change-name}/apply-progress.
• openspec: Read and follow skills/_shared/openspec-convention.md. Update tasks.md with [x] marks.
• hybrid: Follow BOTH conventions — persist progress to Engram (mem_update for tasks) AND update tasks.md with [x] marks on filesystem.
• none: Return progress only. Do not update project artifacts.
