`Claude Code` `v2.1.121`: MCP loading controls, startup resilience, major memory leak fixes

MCP and plugin workflows got sharper, and several multi-GB memory leaks were removed. If you live in long sessions, this update is worth taking now.

[ KEY POINTS ]

MCP servers now support alwaysLoad=true, letting all tools bypass deferred tool search when immediate availability matters.
Startup got harder to break: transient MCP boot failures now auto-retry up to 3 times, and upgraded clients start faster after removing the Recent Activity splash panel.
Long-session stability improved with fixes for image-processing RSS blowups, /usage leaking up to ~2GB, and tool-failure memory leaks.
PostToolUse hooks can now replace output for all tools via hookSpecificOutput.updatedToolOutput, expanding post-processing beyond MCP-only flows.
Quality-of-life upgrades landed across /skills, fullscreen scrolling, wrapped URL clicking, /terminal-setup, and non-interactive CLAUDE_CODE_FORK_SUBAGENT=1 support.

`Antigravity` backlash: editor removed, agent command center takes over

AntigravityAI coding IDE — Google’s agent-first dev tool
The update shifts from a full IDE into an agent hub. Losing file-first editing weakens it as a daily driver; worth watching before switching workflows.
- The core complaint is concrete: files, editor, terminal, and change tracking no longer feel like one controlled workspace.
- A CLI is framed as a poor replacement for a full IDE. For app debugging, terminal-first flow adds friction.
- Cursor and Windsurf were named as competitors that benefit if Antigravity drops its integrated editor.
- Only 5 posts from 3 participants, so this is an early friction signal, not broad market proof.

`Antigravity CLI` `agy` loses auth session in WSL 2

Antigravity CLICoding agent CLI — runs terminal workflows via `agy`
WSL 2 runs trigger browser login on every agy execution. Skip WSL use for now if repeated auth breaks your coding loop.
- Repro path is simple: run agy in Ubuntu on WSL 2, complete Windows browser auth, exit, then run it again.
- Expected behavior is a persisted Linux-side session; actual behavior is fresh authentication every run.
- Reported environment is Windows host plus WSL 2 Ubuntu 22.04.5 LTS, so native Linux/macOS behavior is not covered.

`Antigravity 2.0` backlash: chat-only agent surface removed core IDE controls
50radar
AntigravityAI coding IDE — Google-backed agent-first dev environment
The complaint is not about model quality; it is about losing the editor, terminal, and file tree. Agent IDEs that remove manual control create churn risk, not lock-in.
- The reported change replaces a classic IDE workflow with a chat-first Manager Surface; that breaks fast component edits, terminal work, and Git control.
- The requested fix is a Legacy IDE toggle: keep agent delegation optional while preserving manual file explorer and terminal access.
- The threat to move to Cursor or Windsurf is the useful signal. Coding agents still need IDE-grade escape hatches for daily product work.
