A "ToolSearch for skills" — searches your SKILL.md files by keyword, exact name, or required-term filter so the model can fetch full skill descriptions on demand. Mirrors Claude Code's internal ToolSearch scoring algorithm 1:1, but for skills instead of MCP tools. Pairs with two bundled slash-commands: /optimize-skill-context sets SLASH_COMMAND_TOOL_CHAR_BUDGET=1 to free Claude Code's ~1% skill-description budget (forcing names-only mode), and /restore-skill-descriptions reverses it. Slash-commands keep working; descriptions are fetched on demand via skill_search when relevant. Repo-aware: skills under the current git-root's .claude/skills/ get a +5 score boost over same-named skills from other repos, so search ranking respects which project you're working in.
