Run a local multi-model code review through the user's OpenCode setup BEFORE a pull request is opened. Use this right after finishing an implementation or bug fix in Claude Code, while the changes are still local — uncommitted, or committed on a branch but not yet turned into a PR — and the user wants an independent review pass before pushing. Trigger whenever the user says things like "review my changes", "review before I open the PR", "run the opencode review", "multi-model review", "review this diff", "second opinion on this", or asks for a pre-PR review of work that was just completed, even if they don't name OpenCode explicitly. Returns a consolidated review report on stdout for Claude Code to act on. Do NOT use this for reviewing an already-open GitHub PR — that path is handled interactively in the OpenCode TUI and uses gh.
Review business contracts for risk identification including liability clauses, IP ownership, termination terms, and payment conditions. Use this skill when the user needs a practical contract risk assessment for vendor agreements, partnership contracts, or service agreements — even if they say 'review this contract', 'what should I watch out for', 'is this agreement fair', or 'negotiate better terms'.
Design and implement OKR (Objectives and Key Results) for goal-setting and strategic alignment across organizational levels. Use this skill when the user needs to set team or company goals, align departments to strategy, track quarterly progress, or transition from KPI to OKR systems — even if they say 'set our quarterly goals', 'how does OKR work', 'align team goals with company vision', or 'our goals feel disconnected'.
Use when auditing, trimming, or restructuring AI instruction files (CLAUDE.md, SKILL.md, AGENTS.md) to reduce context-window consumption. Trigger whenever CLAUDE.md is bloated or Claude ignores instructions, a SKILL.md exceeds 120 lines, skills share duplicated content, AGENTS.md has large inline blocks, or the user asks to optimize, slim down, or reduce token usage.
Use the public `orca` CLI to operate Orca-managed worktrees, folder contexts, terminals, repos, automations, worktree comments, and the browser embedded inside the Orca app. Use when the user says "$orca-cli", "use orca cli", "Orca worktree", "child worktree", "cardStatus", "spawn codex/claude in a worktree", "read/wait/send Orca terminal", "terminal send", "full handoff", "handover", "give this to another agent", "another worktree", "Orca browser", or "control the browser inside Orca". Prefer this over raw `git worktree`, ad hoc PTYs, Playwright, or Computer Use when the task touches Orca-managed state. Use Computer Use for browser windows, webviews, or desktop UI outside Orca's embedded browser.
Comprehensive CLI reference and search strategies for osgrep semantic code search. Use for detailed CLI options, index management commands, search strategy guidance (architectural vs targeted queries), and troubleshooting. Complements the osgrep plugin which handles daemon lifecycle.
The first step in contributing to open source on GitHub: find a project. When the user wants to contribute to open source but has not chosen a repository, use the gh CLI to search for candidate repositories based on default criteria (recently active, medium-sized, with good first issues), evaluate and score each for contributor-friendliness, and output a shortlist with recommendations. Trigger phrases: “find an open-source project,” “what projects can I contribute to,” “help me find an open-source project.” Do not use this skill if the user has already specified a repository; use oss-triage / oss-contribute instead.
Capture current page layout, styles, and structure from a live web page using PinchTab browser automation. Use when you need to understand the existing UI before making changes — captures screenshots, DOM structure, computed styles, and layout properties. Useful as a pre-implementation baseline for frontend or UI-affecting changes.

Search for people and properties using Whitepages APIs via x402. USE FOR: - Finding people by name and location - Address lookups and verification - Property owner information - Background research (with legitimate purpose) TRIGGERS: - "find person", "lookup person", "who lives at" - "property owner", "property search", "address lookup" - "person at address", "contact info for" IMPORTANT: These endpoints contain personal information. Use responsibly and only for legitimate purposes. See rules/privacy.md for guidance. Both endpoints are $0.44 per call. IMPORTANT: Never guess endpoint paths. All paths follow the pattern https://enrichx402.com/api/{provider}/{action}. Use exact URLs from the Quick Reference table below or call x402.discover_api_endpoints first.
Diagnose why Claude Code is (or isn't) prompting for permission. By default reads only repo-local layers (CLI project, CLI project-local, VSCode workspace). Host-global layers (CLI user `~/.claude/`, VSCode user settings) are read ONLY when the user explicitly confirms — those files may contain unrelated paths or secrets. Use when user says "why is it asking me to approve?", "permission check", "why am I getting prompts?", "bypass isn't working", "check my permissions". Read-only diagnostic.

Use when the user wants to generate images from the current agent context through configured PicGen providers. Trigger directly only on explicit image-generation requests or when the user names PicGen; ask for confirmation for strong visual-output intent; only suggest PicGen for weak visual exploration intent.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
