- What Is MCP? Model Context Protocol Explained (2026)
  https://pristren.com/blog/what-is-mcp-model-context-protocol
  MCP is the open standard that lets Claude Code, Cursor, and Copilot call your tools and APIs through one protocol — here is how it works and why it matters in 2026.

- How to Set Up MCP Servers in Claude Code and Cursor
  https://pristren.com/blog/how-to-set-up-mcp-servers-claude-code-cursor

- Best MCP Servers for Developers in 2026
  https://pristren.com/blog/best-mcp-servers-developers-2026
  The MCP servers developers actually use in 2026 — GitHub, Playwright, databases, Figma, observability — ranked by workflow impact and context cost. Install three to five max.

- Why Does MCP Use So Many Tokens? (And How to Fix It)
  https://pristren.com/blog/mcp-token-bloat-how-to-fix
  MCP tool definitions can eat half your context window before you prompt. Here is why — and six fixes that actually work in Claude Code and Cursor.

- How Do Claude Code Skills Work? Complete SKILL.md Guide
  https://pristren.com/blog/claude-code-skills-guide-skill-md
  Skills are SKILL.md playbooks Claude Code loads on demand — encode your team workflows once, trigger by slash command or context match. No more copy-pasting deploy checklists.

- Skills vs MCP: When to Use Which in 2026
  https://pristren.com/blog/skills-vs-mcp-when-to-use-which
  Skills teach the agent your workflow; MCP connects live systems. Here is when to use each — and the hybrid pattern HN devs settled on in 2026.

- Claude Code vs Cursor: Token Cost and Efficiency (2026)
  https://pristren.com/blog/claude-code-vs-cursor-token-cost-2026
  Independent 2026 benchmarks show Claude Code completing the same coding task in ~33K tokens vs Cursor ~188K — here is the dollar math and when each tool still wins.

- OpenCode vs Claude Code: Open-Source Agentic CLI Compared
  https://pristren.com/blog/opencode-vs-claude-code-comparison
  OpenCode runs Claude, GPT, Gemini, or local Ollama models in one terminal agent — Claude Code is official, polished, and Anthropic-native. Honest 2026 comparison.

- What Should Go in CLAUDE.md? Best Practices for 2026
  https://pristren.com/blog/claude-md-best-practices-2026
  CLAUDE.md is the file Claude Code reads every session — keep it under 200 lines with stack, commands, and boundaries; move long workflows to skills.
