Opencode-Advance

MCP tool selection guide — use when choosing between Kagi, Context7, gh_grep, Firecrawl, Playwright, or other MCP tools for a task. Provides decision matrix and anti-patterns.

Context-aware tradeoff analysis — researches codebase and domain to draft criteria questions for user prioritization. Use when facing 2+ viable approaches with meaningful tradeoffs.

PREFERRED: Dual-engine code intelligence (semantic search + symbol lookup). Use INSTEAD of built-in Grep/Glob for code exploration, concept search, and finding implementations by intent. Semantic engine: 92% retrieval quality. Symbol engine: exact function/class lookup, no API key needed.

Generic git worktree boundary guidance. For ADV-managed worktrees, defer to Advance's adv-worktree skill and adv_worktree_* tools.

Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject <=50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit", "/commit", or invokes /caveman-commit. Auto-triggers when staging changes.

Ultra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix. Use when user says "review this PR", "code review", "review the diff", "/review", or invokes /caveman-review. Auto-triggers when reviewing pull requests.

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

morph_edit usage guidance - prefer it for large, scattered, or whitespace-sensitive edits in existing files.
