Weekly brief

Aug 10, 2026

Claude Code August 10: Auto Mode Becomes the Default on Pro, Max and Team From August 14, v2.1.226 Is the Latest CLI, and Self-Hosted Runners Enter Public Beta

The big change this week is not a feature, it is a default.
From August 14, 2026 auto mode is on by default for Claude Code on Pro, Max and Team, with prompt-injection screening and customizable hard deny rules shipping alongside it.
Anthropic's own numbers explain why: auto mode caught 89% of harmful actions in a 1,053-user test against 13.6% caught by human review, because users approve 97% of permission prompts anyway.
Five CLI releases landed in six days, v2.1.222 through v2.1.226, closing a Bash permission bypass, hardening worktree isolation, adding gateway spend-limit warnings and fixing a burst of MCP OAuth 401 errors on macOS.

OpenAI Codex August 10: Codex CLI 0.147.0 Ships Portable Agent Plugins, the --approve-for-me Flag and Cursor Skill Import, and Sottiaux Says Today's Codex Will Seem Primitive in 2 to 3 Months

Codex CLI 0.147.0, out August 7, is the biggest CLI release in weeks: portable Agent Plugins with local, personal, workspace and remote catalogs, a new --approve-for-me flag for automatically reviewed approvals, import of Cursor-managed skills, and opt-in support for the MCP 2026-07-28 protocol with paginated discovery and non-blocking server startup.
It also redacts secrets and complete bearer tokens from displayed commands and replayed history, and removes the deprecated codex exec --full-auto flag, so anyone scripting Codex has a migration to make.
On the roadmap side, OpenAI core products lead Thibault Sottiaux says Codex will seem primitive in 2 to 3 months, with Codex now past 8 million users and the planned Ona acquisition pointing at persistent cloud agents.
Move your scripts off --full-auto to --sandbox workspace-write now.

Existing Free users in India upgrade from the dashboard.

FAQ

What is Skillselion?

An automatically updated directory of skills, MCP servers and marketplaces for Claude Code, Codex, Cursor and other coding agents - ranked by real installs. It doubles as a research organization: Skillselion Research publishes dated censuses and open datasets measuring the ecosystem itself.

Does Skillselion publish research?

Yes - that is what separates it from a plain directory. Skillselion Research runs ongoing censuses of the agent ecosystem (security audit coverage, verified copies, install-weighted use cases, code maintenance) plus an always-current statistics reference. Every edition is frozen on publication, free to cite with attribution, and ships its raw dataset as CSV. How the numbers are made is at /research/methodology.

How are listings chosen?

Automatically updated and ranked by real adoption - we track installs and GitHub stars across Anthropic, OpenAI and Cursor tools so you find and compare what is actually used.

Does it cost anything?

No. Browsing, search and the brief are free.

Is Skillselion affiliated with Anthropic, OpenAI or Cursor?

No. Independent project, not affiliated with or endorsed by any tool maker.

Do I need an account?

No - everything here is free to browse without one.

Do you check listings for security?

Not ourselves. Listings surface third-party audit verdicts (Socket, Snyk and other skills.sh auditors) where they exist - outside signals we pass through, not a scan we run and not a safety guarantee. Our Agent Skill Security Census measures that coverage across the whole ecosystem: 87.8% of listings have never been audited by anyone. Review a tool before you install it.

How do I report an inaccurate listing or suggest a tool?

Send us a note through the Feedback page. We read every message - whether it’s a stale entry to fix or a tool we should add. The directory is updated automatically and ranked by real installs.
