The Claude Agent SDK is the Claude Code engine stripped down to a library. Same agent loop, same built-in tools, same context handling, but you call it from your own Python or TypeScript code instead of the CLI. If you’ve used Claude Code to read files, run shell commands, search codebases, and edit code, the SDK points that same machinery at any problem you want. No human needs to sit in the loop.

Yes, you can point Claude Code at a 541,909-row retail dataset and walk away with a six-sheet Excel workbook, professional charts, and a parameterized report script, without opening a Python file or debugging a single line of code. The complete workflow takes roughly 15 to 20 minutes from raw data to finished output.

The goal is real delegation. Claude handles setup, cleaning, math, and charts. You focus on the right questions to ask.

Passkeys swap passwords for a public/private keypair kept in the device keychain and unlocked by Face ID, Touch ID, or Windows Hello. The WebAuthn API does the crypto work, while @simplewebauthn/server version 13.3.0 covers Node, Bun, and Deno backends. Sign-up, autofill login, and account recovery all fit in one evening of work.

What Passkeys Actually Are and Why 2026 Is the Year to Ship Them

A passkey is a public/private keypair made on the user’s device. The private key never leaves the secure enclave (Secure Enclave on Apple hardware, StrongBox on Android, TPM on Windows). Only a signed challenge travels over the wire. Your server stores no shared secret to steal and no hash to crack offline. The signature is bound to your domain, so it can’t be phished. If a user visits examp1e.com instead of example.com, the browser refuses to sign. Credential phishing ends at the protocol layer.

Drop a few ESP32 boards ($3-8 each) flashed with ESPHome ’s Bluetooth Proxy firmware into rooms where BLE devices drop out. Home Assistant then routes Bluetooth traffic through the nearest proxy on its own. Each proxy adds about 10-15 meters of BLE coverage through interior walls, needs only a USB power cable, and works with HA’s native Bluetooth setup. The BLE devices themselves need no config changes. They have no idea they’re talking through a relay.

Anthropic ships claude-code-action , an official GitHub Action that runs the full Claude Code runtime inside your CI/CD pipeline. It reviews pull requests, builds features from issues when someone types @claude, writes tests, updates docs, and drafts release notes. It also respects your repo’s CLAUDE.md coding rules. The runtime runs on a GitHub Actions runner, with tool use, file reads, and multi-step reasoning.

It ships with four auth backends: Anthropic API, AWS Bedrock, Google Vertex AI, and Microsoft Foundry. It also has a sister claude-code-security-review action for vuln scans, native GitLab CI/CD support, and real deployments. Deriv runs it across 700+ repos, handling 100+ PRs per week. So this has moved past the demo stage. Teams now wire it into merge gates next to linters and test suites.

If you spend eight-plus hours a day in a terminal and an editor, the right pointing device counts as much as the right keyboard. The Logitech MX Vertical remains the default vertical pick. It has a 57-degree handshake angle, a 4000 DPI sensor, and solid Linux support via Solaar and logiops . For a thumb trackball, the Logitech MX Ergo S wins on tilt and 120-day battery life. The Kensington SlimBlade Pro leads the finger and palm trackball field with its 55mm billiard-grade ball and Bluetooth LE. For open-source fans, the Ploopy Classic 2 with QMK firmware ships as a fully user-fixable device. Linux sees it as a standard HID mouse with zero closed drivers.
