@playwright/mcp uses an accessibility tree instead of screenshots, cutting token cost by 10–50x — the best default for AI agents doing web automation. Puppeteer MCP fits screenshot-heavy tasks. Direct CDP via MCP is for low-level tooling or domains that Playwright/Puppeteer don't expose.
@playwright/mcp defaults to an accessibility tree (browser_snapshot) instead of screenshots, cutting token consumption by 90%+. Combined with Playwright's native auto-wait, it's the best starting point for AI agents doing web automation.
server-puppeteer is the Puppeteer wrapper in the official MCP servers monorepo — seven lean tools built around screenshots and evaluate. Token cost is significantly higher than @playwright/mcp per interaction, but it fits well when the screenshot itself is the deliverable or custom JS execution is the core need.
A Go read-only scanner open-sourced by Perplexity in May 2026 (v0.1.1, zero non-stdlib dependencies). It inventories npm/PyPI/Go/RubyGems/Composer/MCP/editor and browser extensions into NDJSON, matches against a custom exposure catalog, and answers the question 'which machines in my fleet are currently affected' the moment a supply chain incident hits. It deliberately never invokes any package manager and is not an EDR.
Warp evolved from a Rust-powered modern terminal into an AI Agent-integrated development environment (ADE), open-sourced under AGPL in April 2026, with over 700,000 developer users.
Better Agent Terminal (BAT) is an Electron desktop app that unifies multiple project workspaces, terminals, and Claude Code Agents into a single window — solving the everyday pain of exploding iTerm tabs and the lack of a proper GUI container for agents. MIT License, available on macOS, Windows, and Linux.
oh-my-codex (OMX) doesn't replace Codex CLI — it adds a structured workflow layer on top of it. From requirements clarification and plan generation to multi-agent parallel execution, four core Skills transform scattered prompt conversations into a trackable development process.
Top Silicon Valley companies are independently building internal AI coding agents that automate everything from a Slack message to a merged PR. This article deep-dives into architectures from Stripe, Ramp, Coinbase, and Spotify, then expands to cover Google, Meta, Amazon, Uber, Goldman Sachs, Walmart, and more.
Skill paths are almost always runtime-specific. AGENTS.md is the reliable way to share rules across agents. Put personal reusable capabilities in each agent's supported global directory; put project workflows inside the repo.
GitBook is a Git-based documentation platform with Markdown editing, version control, and multi-user collaboration. Ideal for technical docs, API references, and internal knowledge bases. The free plan is sufficient for individuals and small teams.
A breakdown of nine major documentation platforms — their positioning, pros, cons, and ideal use cases. Decision logic: open-source projects → Docusaurus/VitePress, API docs → Mintlify/ReadMe, internal enterprise → Confluence, fastest to launch → GitBook.
Agent CLIs are not smarter autocomplete tools -- they are AI agents that can read your codebase, execute multi-step tasks, and operate in real environments. Claude Code, Codex CLI, Gemini CLI, OpenCode, Aider, Pi, Kiro, Amp, Cursor CLI... the tools keep multiplying, but they all share a common set of design principles -- understanding these principles is how you actually get good at using them.
