dsh-skill-indexer: A Two-Stage Intent Retrieval Plugin for Local SKILL.md

dsh-skill-indexer is a Host Bundle plugin for DSH, designed to address the challenge agents face in precisely locating local SKILL.md files. It establishes a two-level indexing mechanism that leverages keyword coverage and IDF for intent routing, supporting a three-state fallback (hit/low/miss). The tool runs entirely locally with zero dependencies, offers both command-line and programmatic invocation, and supports hash-based incremental updates.
