dex

Locates files, directories, and components relevant to a feature or task. Call with a human language prompt describing what you're looking for. Ideal for multi-pass searches across file names and content.

Finds similar implementations, usage examples, or existing patterns that can be modeled after. Returns concrete code examples with file:line references. Like codebase-locator, but also reads and extracts code details.

Use this agent proactively when the user needs documentation, implementation guidance, or technical research for any library, framework, API, or technology. Examples: <example>Context: User needs help with a React framework feature. user: 'How do I implement React hooks with TypeScript?' assistant: 'I will use the documentation-research-agent to get the latest React and TypeScript documentation to provide you with the best implementation approach.' <commentary>Since the user needs documentation about React and TypeScript, use the documentation-research-agent to fetch comprehensive documentation.</commentary></example> <example>Context: User wants to integrate a payment system. user: 'I need to integrate the Stripe payment API into my checkout flow' assistant: 'Let me use the documentation-research-agent to retrieve the latest Stripe documentation and create an implementation plan for your checkout integration.' <commentary>The user needs API documentation and implementation guidance, so the documentation-research-agent should be used.</commentary></example> <example>Context: User needs help with a database library. user: 'Can you help me set up Prisma ORM with PostgreSQL?' assistant: 'I\'ll use the documentation-research-agent to fetch the latest Prisma and PostgreSQL documentation to guide you through the setup process.' <commentary>The user needs documentation for database tools, use the documentation-research-agent for comprehensive guidance.</commentary></example>

Efficiently extracts implementation context from large plan files using grep patterns. Use this agent before implementing a plan to reduce context window usage. Pass the plan file path and optionally a specific phase number.

Deep-dive research agent for analyzing documents in the thoughts/ directory. Use when you want to extract high-value, actionable insights from research documents, plans, or notes.
