/specforge:plan — design HOW to build it

Translate an approved spec into a concrete technical plan. This is the Construction design step. Consider delegating to the architect subagent. The human's approval of this plan is what unblocks code edits (together with the spec approval).

When to use

• A feature spec exists and the user is ready to design the implementation.
• Trigger words: "plan", "design", "architecture", "how should we build".

Preconditions

• The active feature's spec.md should be reviewed. Ideally specify is already approved (/specforge:approve specify). If the spec still has [NEEDS CLARIFICATION], run /specforge:clarify first.
