Claude Prompt Best Practices: The 6-Band Framework By Mario Alexandre March 21, 2026 sinc-LLM Prompt Engineering Claude's Strengths and the 6-Band Framework Anthropic's Claude models are known for instruction-following, safety awareness, and long-context handling. These strengths make Claude particularly responsive to structured prompting, when you provide clear specifications, Claude follows them precisely. The sinc-LLM framework was developed using Claude-based multi-agent systems as primary test subjects. All 275 observations in the research paper were collected from Claude-powered agents, making this guide especially relevant for Claude users. The 6 Bands for Claude x(t) = Σ x(nT) · sinc((t - nT) / T) The 6 specification bands, with Claude-specific notes: PERSONA , Claude responds well to specific expertise roles. "You are a distributed systems architect" produces better output than "You are helpful." CONTEXT , Claude's long context window (200K tokens) means you can include extens
