[deep-report] Improve Claude Code onboarding: add ANTHROPIC_API_KEY walkthrough parallel to COPILOT_GITHUB_TOKEN #31727

Context

Identified by DeepReport intelligence briefing 2026-05-12 (Claude Code User Documentation Review #31687).

The review found that gh-aw's Quick Start is Copilot-first for non-Copilot users. Specifically:

• Examples reference engine: copilot roughly 7× more often than engine: claude
• The only engine-specific setup callout in Quick Start is for COPILOT_GITHUB_TOKEN (4 lines in quick-start.mdx line 76-79)
• There is no equivalent walkthrough for ANTHROPIC_API_KEY despite Claude being a fully-supported, first-class engine
• The security architecture diagram literally renders "Copilot CLI" as the agent box

Overall assessment from the review: 7/10 — "adopt-able with friction, not blocked."

Expected Impact

• Lowers onboarding friction for Claude users (a significant portion of the target audience)
• Brings Quick Start in line with engines.md's engine-agnostic stance
• Reduces ad-hoc support questions about Claude setup

Suggested Approach

• Add a parallel ANTHROPIC_API_KEY setup NOTE box in quick-start.mdx Step 2 mirroring the existing COPILOT_GITHUB_TOKEN block
• Mix engine: claude examples into the README/quick-start so the ratio is closer to 1:1
• Make the architecture diagram engine-agnostic ("Agent CLI" instead of "Copilot CLI")

Suggested Agent

Documentation-capable coding agent (Claude or Copilot).

Estimated Effort

1-2 hours of agent time.
