description	Reusable planning and iteration patterns drawn from multiple winning projects in Claude’s “Built with Opus 4.7” hackathon.

Instructions

Use this skill as a checklist of proven build patterns highlighted by hackathon winners.

1. Plan before you build

• Write a short spec and a step-by-step plan before implementing.
• Separate responsibilities (e.g., design, ingestion, core logic) so you can iterate cleanly.

2. Parallelize intentionally

• Split work across multiple Claude Code sessions when components have distinct contexts.
• When debugging, try multiple agents in parallel with one agent per domain.

3. Treat Claude as a thought partner

• Brainstorm options and ask for alternatives (including challenging initial assumptions).
• Ask Claude to audit what you already built before starting the next feature.

4. Evaluate early

• Build an evaluation process early, and prioritize it ahead of adding features.
• Consider injecting domain-specific reference data (e.g., a JSON knowledge file) into each run where relevant.
