GitHub Copilot Sandboxing

GitHub Copilot Sandboxing is GitHub's answer to the "agent with full shell access" problem: two complementary isolation modes for running GitHub Copilot CLI agent sessions, both in public preview. Local sandboxing wraps the commands an agent runs on your machine in an OS-level sandbox powered by Mic

Terminal Multiplexers

Programs that let you run multiple terminal sessions inside a single terminal window or remote connection. Key capabilities: split panes, multiple windows/tabs, session persistence (detach/reattach), and remote session survival (SSH disconnects don't kill your processes).

Obsidian Callouts

Callouts are styled block elements in Obsidian that highlight important information using a special blockquote syntax. They replace the older Admonition plugin for Obsidian approach with a native, built-in feature.

Obsidian URI

Obsidian URI is the custom `obsidian://` protocol that Obsidian registers with the operating system. It lets any external application (browser, launcher, task manager, script) open vaults, jump to notes, run searches, and create content. No plugin needed; this is the official way to control Obsidian

Agent Plugins - one package format for skills and MCP servers

A new open specification landed: Agent Plugins 1.0, with an initial technical steering committee made of Amazon, Cursor, Microsoft, OpenAI and Vercel. It defines a portable package format for extending agents, so an extension is authored once instead of being repackaged per client.

Remotely Save plugin for Obsidian

Remotely Save, synchronizes an Obsidian vault with cloud storage you already have: Dropbox, OneDrive, Google Drive, any WebDAV server, or S3-compatible object storage (AWS S3, Cloudflare R2, MinIO, Backblaze B2, and similar). It is a lightweight alternative to Obsidian Sync for people who prefer to

OpenRouter adds unified audio transcription

OpenRouter extended its "one API for every model" promise to speech-to-text. A new endpoint (`POST /api/v1/audio/transcriptions`) accepts base64-encoded audio and returns the transcript as JSON, using the same API key as chat completions. No separate STT provider, no extra server.

OpenAI shrank the Codex context window on purpose

While every model announcement brags about bigger context windows, OpenAI went the other way: the Codex model's context size dropped from 372k to 272k tokens. No announcement; the change surfaced as a pull request in the open-source Codex CLI repo, and promptly hit the Hacker News front page because

Notebook Navigator is now Obsidian's most popular plugin

The Notebook Navigator plugin for Obsidian just hit a milestone: it's now the #1 most popular plugin in the Obsidian community directory, and should pass a million downloads within weeks. Not bad for a file explorer replacement.

Faster coding shifts the bottleneck to the outer loop

Luca Rossi makes a point about AI coding that matches my thinking: most AI coding workflows optimize the INNER loop, the rapid cycle of describing a feature and generating code. But that's a fraction of software delivery. The OUTER loop (deciding what to build, shaping the solution, releasing, learn

Use code for control flow, agents for reasoning

Give deterministic code everything it can handle (routing, scheduling, data transformation, file writes), and reserve the Large Language Models (LLMs)) for the parts that need judgment (interpreting ambiguous, unstructured input).

Orchestrator tax

According to Rahul Garg (Thoughtworks, on martinfowler.com), the real value of a subagent is what it keeps OUT of the orchestrator's context, not how fast it runs. Context isolation is more valuable than parallelism.
