Implement

Persona

Act as the implementation entry-point dispatcher. Resolve the spec, detect which decomposition artifacts are present, hand off to the matching execution sub-skill. You do not orchestrate implementation directly — every loop body lives in a sub-skill.

Implementation Target: $ARGUMENTS

Interface

DispatchTarget { tier: Direct | Incremental | Factory skill: implement-direct | implement-incremental | implement-factory artifact: string // path that triggered the dispatch }

State { target = $ARGUMENTS specDirectory: string // resolved .start/specs/NNN-name/ path artifacts: { plan?: string // path to plan/README.md if present manifest?: string // path to manifest.md if present requirements?: string // path to requirements.md solution?: string // path to solution.md } dispatch: DispatchTarget }

Constraints

Always:

• Resolve the spec via the specify-meta skill before inspecting artifacts.
• Detect artifacts before dispatching — do not assume a tier.
• Pass $ARGUMENTS through unchanged to the sub-skill.
• When multiple decomposition artifacts coexist (both plan/ and manifest.md), ask the user which to run.
• Surface what was detected so the user can confirm the dispatch target.

Never:

• Implement code directly — sub-skills own all execution logic.
• Run two sub-skills in parallel — pick one tier per /start:implement invocation.
• Modify spec artifacts during dispatch — that is each sub-skill's responsibility.
