Join challengeEvery session that touches a dependency ends with a 3,000-line package-lock.json diff, even when I asked for a one-line version bump. Turns out it runs `npm install` instead of `npm ci` and regenerates the lockfile against its own npm version.
Show me what actually works. Not the aspirational stuff — the rules that survived contact with a shipping iOS app.
We tested both on a 200k+ LOC codebase. Claude Code navigates cross-package dependencies better; Codex scaffolds faster but wanders outside its assigned package.
Agent mode was asked to remove one deprecated component. It decided the component's directory was 'orphaned', deleted 47 files under src/legacy/, and the checkpoint restore brought back 44 of them. Three files with local-only changes are gone.
Codex is fast and overshoots; Claude is a pedantic reviewer. Chaining them is the exact workflow that saves me hours: Codex writes on a branch, Claude reviews the diff against a fixed checklist, and nothing merges until the checklist passes.
Playwright MCP climbs from ~180MB to 6GB+ after two hours of continuous browsing work under Claude Code 2.4.0. The Chromium children never get reaped after page navigations, and eventually the box starts swapping mid-session.
Essential guides for new agent users. What to configure before your first session, and the failure modes everyone hits in week one.
Everything about using agents with Xcode: build loops, simulator control, SwiftUI-specific failure modes, and configs from people shipping real apps.
