ultrathink
UltraThink Workflow OS — 4-layer skill mesh with persistent memory and privacy hooks for complex engineering tasks. Routes prompts through intent detection to activate the right domain skills automatically.
Best use case
ultrathink is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
UltraThink Workflow OS — 4-layer skill mesh with persistent memory and privacy hooks for complex engineering tasks. Routes prompts through intent detection to activate the right domain skills automatically.
Teams using ultrathink should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# UltraThink — Workflow OS for AI Agents You have access to UltraThink's skill mesh — a 4-layer architecture of 125+ skills that automatically activate based on intent detection. ## Skill Layers 1. **Orchestrators** — End-to-end workflows (cook, ship, gsd-verify, ut-chain) 2. **Hubs** — Multi-step coordinators (plan, debug, refactor, test, scout) 3. **Utilities** — Reusable tools (fix, verify, quality-gate, commit-crafter) 4. **Domain** — Technology specialists (react, nextjs, tailwind, typescript, prisma) ## When to Use Use UltraThink when the user asks you to: - Build, debug, refactor, or test code in a project - Explore or understand a codebase - Plan an implementation strategy - Review code quality - Search project memory for past decisions ## How to Route 1. Detect the intent category: build | debug | refactor | explore | deploy | test | design | plan 2. Match to the appropriate hub skill 3. If the task is complex (multi-step, cross-file), escalate to an orchestrator 4. For technology-specific work, include the relevant domain skill ## Intent → Skill Mapping | Intent | Primary Skill | Supporting Skills | |--------|--------------|-------------------| | build | cook | react, nextjs, typescript | | debug | debug | scout, fix, sequential-thinking | | refactor | refactor | quality-gate, typescript | | test | test | vitest, testing-patterns | | explore | scout | onboard, code-explainer | | plan | plan | brainstorm, problem-solving | | deploy | ship | verify, cicd | | review | code-review | quality-gate, security-scanner | ## Memory Integration When the `ultrathink-memory` MCP server is available: 1. Before starting work, search memory for relevant context: `memory-search` 2. After completing work, save key decisions: `memory-save` 3. For recurring projects, recall full context: `memory-recall` ## Safety Rules 1. Never expose `.env`, credentials, API keys, or database connection strings 2. Never execute destructive operations without explicit user confirmation 3. Always cite file paths when referencing code 4. For suggest-only mode: provide diffs, never auto-apply
