context-mode is an MCP server that solves one of the most painful problems in long AI coding sessions: context window exhaustion. Instead of dumping raw tool outputs (like a full Playwright snapshot at 56KB) directly into the model's context, context-mode intercepts those outputs, stores them in SQLite with BM25 full-text search, and only surfaces the relevant fragments when the agent queries for them. The result, according to the author's benchmarks, is a 98% reduction in context consumption during extended sessions. The server supports 12 AI coding platforms out of the box — Claude Code, Cursor, Gemini CLI, Codex CLI, Windsurf, and more — and the BM25 retrieval layer means the agent can still find anything it stored, it just doesn't pay the context tax for keeping it all in working memory simultaneously. With 9,195 GitHub stars and strong community endorsement, this is one of the more practically impactful MCP servers to emerge. It doesn't add new capabilities — it makes long-horizon agentic coding sessions economically and technically viable where they previously weren't.

Real-world agent skills for engineers — install via npm, not vibes

Skills is a curated library of AI agent prompts and workflows for real software engineering, created by TypeScript educator Matt Pocock. The project trended to 28,000 GitHub stars with its blunt tagline: "Agent skills for real engineers — not vibe coding." It's a deliberate pushback against chaos-first AI coding in favor of structured, methodical engineering. The library organizes into four categories: Planning & Design (to-prd for converting conversations into PRDs, grill-me for stress-testing plans), Development (tdd for test-driven AI assistance, triage-issue for bug investigation), Tooling & Setup (pre-commit hooks, git safety guards), and Writing & Knowledge (documentation utilities, Obsidian integration). Each skill installs with a single npx command — npx skills@latest add mattpocock/skills/tdd — and plugs into Claude agent setups. With 28,000 stars and 2,200 forks after trending on GitHub on April 27, 2026, Skills has clearly struck a nerve. It's as much a cultural statement as a product: AI coding tools should be used deliberately, with tests, with planning, and with guardrails. The TDD and triage-issue skills address real gaps in how current AI coding agents handle existing codebases rather than greenfield projects.
Reviewer scorecard
“9,195 stars don't lie. If you run Claude Code or Cursor on large codebases, context exhaustion is the number one thing that breaks long sessions. This is a direct fix. Install it, configure your platform, done.”
“The tdd skill alone is worth the install. Watching a Claude agent plan tests before writing implementation is exactly how I want AI to assist me. Matt's framing of 'real engineering vs. vibe coding' is the right cultural correction for 2026.”
“BM25 retrieval works great for structured lookups but can miss contextual relevance in complex multi-file reasoning tasks. You're trading context completeness for context efficiency — that trade-off will bite you on subtle cross-file bugs.”
“These are sophisticated markdown prompts, not magic. If you're already a disciplined engineer, the skills add ceremony without much acceleration. The 28K stars partly reflect Matt's Twitter following — evaluate the actual skills before star-chasing.”
“This is the RAG pattern applied to agent tool outputs — and it signals the emergence of a whole new category: context middleware. As agents run longer and touch more files, the context management layer becomes as important as the model itself.”
“Community-curated skill libraries installed via package managers will become standard infrastructure — as natural as installing a linting config. Skills is the early prototype of a skills ecosystem that will matter at scale.”
“For creative workflows that involve iterating on many assets across a session — mockups, copy variants, design tokens — this means I can keep the full project history accessible without hitting the wall at step 40.”
“The writing and knowledge skills are underrated. The article-editing and Obsidian integration skills bring structured AI assistance to documentation workflows that most agent tools ignore entirely. Install even if you're not primarily a developer.”
