Copilot usage metrics API now names custom skills, agents and MCP servers
GitHub says Copilot usage metrics now show the configured names of the skills, custom agents, Model Context Protocol (MCP) servers, slash commands and plugins that an organization creates, instead of grouping them under other or custom. It builds on the agentic CLI customization metrics released in September.Claude Code 2.1.309 fixes sandbox and permission-check bypasses and changes how `sed -i` and `rm` are handled
Claude Code v2.1.309, released October 22, 2026, per its release notes:Anthropic advises folding subagents into the main agent loop, with a migration kit
In an article dated October 22, 2026, Anthropic's Applied AI team says that in several enterprise deployments on Claude Platform, a single agent using skills and tool search frequently beat both a one-prompt design and a subagent design on quality, often at lower cost and latency. It says one customer saw roughly 2x faster runtime moving from a multi-agent harness to a single loop. These are Anthropic's own observations, not published measurements.Anthropic says Claude wrote formal proofs that 123 open-source libraries cannot crash
In a collaboration with Theorem, Anthropic says it used Claude to prove security properties at the assembly level (RISC-V) in over 100 real-world open-source libraries, which it calls the first large-scale use of AI to formally verify production software at that level.Anthropic donates the Agent Skills standard to the Agentic AI Foundation
Anthropic announced on October 22 that it is donating Agent Skills to the Agentic AI Foundation (AAIF), the foundation it earlier donated MCP to. Anthropic says the standard has been integrated by more than 70 agent platforms since December 2025, including ChatGPT, Cursor, GitHub Copilot and VS Code.GitHub Copilot CLI 1.0.103 retires the legacy --remote flags and extends sandbox support
GitHub Copilot CLI 1.0.103, dated October 22, 2026, per its release notes:OpenCode v1.19.4 upgrades its bundled Bun runtime for security fixes

According to the release notes, that version includes security fixes for Brotli, TLS, HTTP/1.1, HTTP/2, HTTP/3, WebSocket and fetch, and updates the root certificates to NSS 3.131.1. The release notes list no other changes.Amp lets you self-host orbs, free for individuals and teams
Thorsten Ball announced on X that orbs, a feature of the Amp coding agent, can now be self-hosted. He says self-hosting is free for individuals and teams. Details are in Amp's news post, "Self-hosted orbs".
OpenAI publishes an official command-line tool for its API
OpenAI published openai-cli on GitHub, which it calls the official CLI for the OpenAI REST API.

The older version, 2023-06-01, is not deprecated.Claude Security now scans continuously and tracks fixes
Anthropic announced on October 21 that Claude Security, in public beta on Claude Enterprise, now keeps its findings current as code changes. After repositories are connected once, Claude runs a deep first scan and then re-scans as changes land.
