/aide:build — Build Phase

Agent: This command is executed by the aide-implementor agent.

Execute the architect's implementation plan. This is the implementor phase in build mode — the session that turns plan.aide into working, tested code without making architectural decisions mid-session.

Checklist

• Read plan.aide in the target module. This is the primary input — it names files, sequencing, contracts, and which existing helpers to reuse
• Read the intent spec (.aide or intent.aide) for the target module. The plan tells you what to build; the spec tells you what counts as correct
• Execute the plan steps top-to-bottom. Check each checkbox in plan.aide as you complete it. Do not reorder steps, skip steps, or add steps. If a step is ambiguous, stop and escalate back to the architect via /aide:plan rather than inventing an answer
• Write the code. No architectural improvisation — if a decision is not in the plan or the spec, it is out of scope for this session
• Write tests covering every behavior the spec's outcomes.desired names, plus regression coverage for anything in outcomes.undesired
• Run the tests until green
• Run the type checker (tsc --noEmit or the project's equivalent)
• Run aide_validate to check for spec issues introduced during the build
• Hand off to /aide:qa — the QA agent will compare actual output against the spec's outcomes block
