release / tag (push) Has been cancelled
Phase 2 of mathias/skills extraction. Adds two new per-tool wirers alongside Claude Code: - Crush — ~/.config/crush/skills/<name>/SKILL.md (charmbracelet/crush, successor to opencode-ai/opencode which is archived) - Antigravity — ~/.gemini/antigravity/skills/<name>/SKILL.md (Google VS Code extension). Our SKILL.md frontmatter (name + description) is already in the format Antigravity expects — no manifest translation step needed. Both wirers added to Taskfile.yml (install:crush + install:antigravity) and install.sh (wire_crush + wire_antigravity). The aggregate `install` target now calls all four targets (claude:global, claude:repo, crush, antigravity). Idempotent symlinks, same shape as the Claude Code wirer. Per-host env overrides documented in README: SKILLS_REF for tag pinning, CRUSH_SKILLS_DIR + ANTIGRAVITY_SKILLS_DIR for non-default paths. Skipped: - opencode (opencode-ai/opencode): archived, succeeded by Crush; its Custom Commands surface is user prompt templates, not system skills - gitea-resident agents: consume via per-repo .claude/skills or brain MCP, no special target needed Bump-Type: minor
