Auto-detect and load minimal context from Skills folders using progressive disclosure, trimming 1400 tokens from system prompt through metadata-first loading. Use when optimizing token usage, managing multiple skills, or preventing context bloat. Load YAML metadata first, then conditionally load full SKILL.md only for matched skills based on task triggers. Achieves 10% accuracy improvement via targeted context. Triggers on "optimize skills", "reduce tokens", "smart loading", "skill efficiency".

Systematic workflow for researching and validating blockchain RPC providers. Use when evaluating RPC providers for historical data collection, rate limits, archive access, compute unit costs, or timeline estimation for large-scale blockchain data backfills.
