What does a PD-L1 TPS score of 50% mean for immunotherapy eligibility?
A PD-L1 Tumor Proportion Score (TPS) of 50% means that at least half of the viable tumor cells tested express the PD-L1 protein. In oncology, this is considered high PD-L1 expression. Here is what tha…
What is the difference between osimertinib and erlotinib for EGFR-mutant lung cancer?
Osimertinib and erlotinib are both targeted therapies used to treat non-small cell lung cancer (NSCLC) with mutations in the epidermal growth factor receptor (EGFR). They work by inhibiting the EGFR p…
how can we use ecorouter if we want to start or scale a small business?
To support your business, EcoRouter can help manage your information and streamline your AI usage as you grow. Here is how you can use it: Organize Team Knowledge: As a small business, you can use Com…

Florence Pannell (born Florence Ada Bethia Neate) was a British beauty care businesswoman and a supercentenarian. She was born in Kensington, London, on December 26, 1868, and passed away on October 2…
tell me more about time to first joy?
"Time to First Joy" (TTFJ) is the emotional and creative counterpart to "Time to First Byte." While technical metrics measure how fast a server responds, TTFJ measures how fast you feel a sense of acc…
How do I know when a vibe-coded prototype needs to be re-architected for production scale?
Transitioning from a "vibe-coded" prototype to a production-ready system is a shift from prioritizing speed of experimentation to prioritizing reliability, observability, and cost-efficiency. You gene…
How do subagents work in Claude Code, and when should I use them for larger tasks?
In Claude Code, subagents act as focused, autonomous "helpers" that can be spun up to tackle specific, bounded sub-tasks while the main agent maintains the overarching goal. Here is how they function …
What security risks are common in AI-generated code, and how do I plan to catch them?
When using AI to generate code, it is best to treat the output as a "draft from a well-read intern"—capable but prone to subtle errors. AI often prioritizes functionality over security or relies on pa…
How do I ask an AI to refactor messy code without breaking existing features?
To safely refactor code using an AI, the key is setting strict boundaries around behavior and taking an incremental approach. Here is a practical strategy and a ready-to-use prompt template. --- 1. Th…
What are MCP servers, and how do they extend what Claude Code can do?
MCP stands for Model Context Protocol. It is an open standard designed to let AI models—like Claude—interact securely and consistently with external data, tools, and systems. Think of it as a universa…
How should I plan authentication, user accounts, and permissions before vibe coding an app?
Before you start "vibe coding"—where the focus is on momentum and creative flow—you need a solid blueprint for identity and access. If you skip this, you’ll end up refactoring your entire database sch…
How do I prompt an AI to write meaningful automated tests for my code?
To get meaningful automated tests from an AI, you need to move beyond asking it to "write tests" and start describing the behavior and edge cases you care about. Here is a simple framework for prompti…
What should I do when an AI coder keeps going in circles and reintroducing the same bug?
When an AI coder gets stuck in a loop, it is usually because it has lost the "context" of the error or is prioritizing one instruction at the expense of another. Here is how to break the cycle: 1. Hal…
How should I design a database schema before asking an AI to build features on top of it?
Designing a database schema before involving an AI is a great practice. It ensures that your data architecture remains logical, scalable, and aligned with your business rules rather than just a model'…
What is plan mode in Claude Code, and when should I use it?
In Claude Code, Plan Mode is an interactive feature that prompts the agent to outline its proposed strategy before it begins executing any changes to your codebase. When you trigger Plan Mode, the age…
How do I deploy my first vibe-coded web app so other people can use it?
Deploying your first app is an exciting milestone. Since "vibe-coding" typically involves creating apps through natural language prompts, you likely have a project consisting of HTML, CSS, and JavaScr…
How do I give an AI coder useful context about my existing codebase?
To give an AI coder useful context, focus on structure and intent rather than dumping your entire codebase. AI models perform best when they have a map of the territory and clear constraints. Here are…
What is a CLAUDE.md file and what should I put in it?
A CLAUDE.md file is a plain-text document used to provide context and instructions to AI coding assistants (like Claude, though the convention is adopted by various tools) when they are working within…
What is an API key, and how do I keep it safe when vibe coding?
An API key is essentially a unique digital password—a long string of characters—that acts as your identification when you connect your code to an external service, like OpenAI, a database, or a cloud …
Should I ask an AI coder for one big feature at once or break it into small steps?
Breaking it into small steps is much better. When you ask for a large feature all at once, the AI is more likely to lose track of details, make assumptions that don't match your vision, or encounter "…
