Temperature controls creativity vs. accuracy. Context is everything.**Agents** loop until a*task*is done (not just a sentence). They use tool calling to bridge the LLM and the outside world — reading files, searching the web, running commands.**MCPs**(Model Context Protocol servers) are plugins for your coding agent — they add tools and context. Top picks:[Context7](https://context7.com)(library docs),[Serena](https://oraios.github.io/serena/)(semantic code editing + memory),[Ponytail](https://github.com/DietrichGebert/ponytail)(prevents overengineering).**Skills** are mini-prompts that teach the agent best practices for a specific task.\n\nDOs and DON'Ts:\n\n| Do | Don't |\n|---|---|\n| Constrain agents (stricter environment = fewer mistakes) | Obsess over prompt engineering — just say what you want |\n| Use strongly typed languages with good compiler errors | Let agents write your tests (they confabulate passing tests) |\n| Write the API surface yourself, let LLMs fill in details | Start brand-new ambitious projects with an agent |\n| Use agents for big refactors (their best use case) | Thrash the context window with too much data |\n| Write your own tests so agents catch their own mistakes | Force agents to re-learn your codebase every session — use memory |\n| Get good at code review — it's now a core skill |\n\n[ 5 Agent Skills I Use Every Day](https://www.aihero.dev/5-agent-skills-i-use-every-day) — Matt Pocock, Mar 2026\n\nA practical skill-based workflow for getting high-quality code out of AI agents. Core idea: agents are engineers with no memory, so you need strict, repeatable processes.\n\nThe five skills:\n\n| Skill | What it does |\n|---|---|\n`/grill-me` |\nForces the agent to interview you exhaustively before coding — walk every branch of the \"design tree\" until you reach shared understanding |\n`/to-prd` |\nConverts the conversation into a Product Requirements Document with user stories, submitted as a GitHub issue |\n`/to-issues` |\nBreaks the PRD into a Kanban board of vertical-slice issues (thin cuts through all layers, not horizontal slabs) |\n`/tdd` |\nRed-green-refactor loop — write one test, implement, refactor. Most consistent way to improve agent output quality |\n`/improve-codebase-architecture` |\nWeekly audit: find shallow modules, tightly coupled code, and unclear test boundaries. Better structure → better AI output |\n\nKey insight: **\"If you have a garbage codebase, the AI will produce garbage within that codebase.\"** Invest in deep modules with thin interfaces so agents can navigate easily.\n\nFull skill set + install: [aihero.dev/skills](https://www.aihero.dev/skills) · [GitHub](https://github.com/mattpocock/skills)\n\n[ Zo-topia: My Computer In The Cloud](https://www.jplhomer.org/posts/zo-topia-my-zo-computer-experience/) — Josh Larson, Jan 2026\n\nDeveloper's deep dive into Zo as a personal cloud computer. Highlights:\n\n**What makes it click:** A remote Linux box + AI-native OS + text/email interface. You can text or email your computer from anywhere — even via Siri while driving.**Sites** are Zo's pre-packaged dev templates (Bun-powered) with preview → production workflow. Good for vibe-coding.**Security mindset:** Treat Zo as a separate computer. Be intentional about what data you give it. Ask: \"How damaging would it be if this leaked?\"\n\n[ Zo Computer as a No-Code Build/Host All-in-One Tool](https://www.reddit.com/r/nocode/comments/1qqkkww/zo_computer_as_a_nocode_buildhost_allinone_tool/) — r/nocode, Jan 2026\n\nCommunity discussion on Zo for non-technical users:\n\n- Collapses setup, deployment, hosting, and automation into one conversational flow — the real friction for beginners is\n*after*code is generated, and Zo handles that.\n\n| Term | What it means |\n|---|---|\nLLM |\nLarge Language Model — the AI \"brain\" that predicts text |\nToken |\nSmallest unit of text an LLM processes (a few characters) |\nContext window |\nHow much text the LLM can \"see\" at once (bigger = more expensive) |\nTemperature |\nControls randomness: low = focused, high = creative |\nAgent |\nAn LLM that loops + uses tools until a task is complete |\nMCP |\nModel Context Protocol — plugin system for AI agents |\nSkill |\nA packaged set of instructions an agent can call for a specific task |\nTool calling |\nHow agents interact with the outside world (read files, search, run code) |\nVibe coding |\nBuilding software by describing what you want in natural language |\n\n*Last updated: Jul 16, 2026*", "url": "https://wpnews.pro/news/ai-knowledge-base-articles-guides-and-lessons-learned-about-ai-tools-and", "canonical_source": "https://gist.github.com/j-alicia-long/8aa7a8529921b1ca881939ccad63839e", "published_at": "2026-07-16 17:17:23+00:00", "updated_at": "2026-08-15 16:42:40.457537+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-agents", "developer-tools", "ai-products"], "entities": ["Vhyrro", "Matt Pocock", "Josh Larson", "Context7", "Serena", "Ponytail", "Zo", "GitHub"], "alternates": {"html": "https://wpnews.pro/news/ai-knowledge-base-articles-guides-and-lessons-learned-about-ai-tools-and", "markdown": "https://wpnews.pro/news/ai-knowledge-base-articles-guides-and-lessons-learned-about-ai-tools-and.md", "text": "https://wpnews.pro/news/ai-knowledge-base-articles-guides-and-lessons-learned-about-ai-tools-and.txt", "jsonld": "https://wpnews.pro/news/ai-knowledge-base-articles-guides-and-lessons-learned-about-ai-tools-and.jsonld"}}
