`Claude Code` can charge `ANTHROPIC_API_KEY` before your Max plan

A repo-level .env can silently switch Claude Code from OAuth to API billing on launch. If you run it in CI, cron, or headless scripts, clear ANTHROPIC_API_KEY first or you can leak real money fast.

[ KEY POINTS ]

Support explicitly said env API keys take priority over subscription credentials, and there is no launch warning or billing-switch notice.
The reported loss was $187 across nine auto-recharges while .credentials.json still showed subscriptionType: "max".
Highest-risk setups are headless runs plus shared repos where .env already contains ANTHROPIC_API_KEY for another app or server.
The practical fix is simple: run unset ANTHROPIC_API_KEY or $env:ANTHROPIC_API_KEY = $null before claude -p so billing falls back to OAuth.

GitHub adds REST API auditing for `Copilot` cloud agent repo config
60radar
Repo-level agent settings can now be checked by API instead of manual UI review. Useful for keeping automation permissions visible before cloud agents touch production code.
- New endpoint: Get Copilot cloud agent configuration for a repository, currently in public preview.
- Best fit is policy drift checks across repos: scan whether agent access and configuration match your expected defaults.
- This is governance plumbing, not a coding-speed feature. Worth adopting if Copilot agents run on real repos.

`Copilot Spaces API` is now generally available

Copilot SpacesGitHub Copilot feature — manages task-specific context spaces
Spaces can now be managed from your own apps via API. Useful for wiring repo context into internal tools or repeatable agent workflows.
- The API supports create, read, update, and delete for Spaces, so context setup no longer has to stay inside GitHub UI.
- Good fit for templates: bootstrap a project space per repo, customer, or feature branch and keep agent context consistent.
- This is more automation surface than end-user feature. Value depends on whether Copilot Spaces is already part of the coding workflow.

11 Claude Habits That Compound Over Daily Use

The useful part is not prompt tricks, but persistent context: Projects, CLAUDE.md, styles, skills, and subagents. Worth turning into a default setup before long coding sessions.
- Put codebase context, style guides, and prior PRs into Projects once. Re-pasting the same background is pure context tax.
- A custom style like skeptical senior engineer changes review quality by forcing pushback instead of agreeable code comments.
- In Claude Code, CLAUDE.md carries more weight than session prompts. Around 80 lines of project context can remove repeated stack explanations.
- Use cheaper/faster models by task: Sonnet as default, Opus for architecture, Haiku for batch cleanup like tickets or emails.
- Subagents fit parallel chores: run tests, inspect files, or summarize docs while the main coding thread keeps moving.
