When to choose each

llm-router — Selects the optimal LLM model and provider for each task based on complexity, cost budget, and capability requirements. Routes cheap tasks to Haiku/GPT-4o-mini and complex tasks to Sonnet/Opus/o1. Use when deciding…

42-title-optimizer — Iterative title tag and headline optimizer with multi-round refinement. Generates 5 variations per round across 3 rounds (diverge, refine, polish) with transparent scorin — from chapter42/42-SEO-Skills

Both are free to install. If you're unsure, install both — Claude Code skills are isolated by filename and only collide if their trigger phrases overlap (rare). The richest signal is the SKILL.md body itself — open both skill pages and read the first paragraph of each.
