SkillsHub March 2026 Dev Log: BM25, Rate Limiting, and 5,900+ AI Agent Skills

SkillsHub March 2026 Dev Log: BM25, Rate Limiting, and 5,900+ AI Agent Skills March was a big month for SkillsHub — we shipped v0.2.0 with a completely revamped search engine, proper rate limiting, better docs, and crossed 5,900 skills in the registry. Here's what happened. What's New in v0.2.0 BM25 Multi-Field Scoring The biggest change: we replaced our TF-IDF (v2) skill resolution with BM25 multi-field scoring . If you've used SkillsHub's /resolve endpoint, you'll notice results are significantly more relevant now — especially for ambiguous queries where the old TF-IDF approach would surface noisy matches. BM25 scores across multiple fields (name, description, tags) with field-specific weighting, so a match in the skill name carries more weight than a match buried in the description. It's the same family of algorithms that powers Elasticsearch under the hood.
