Claude Code v2.0.2

What: Added security checks to prevent AWS credential operations before workspace trust is confirmed

Details:

• Both awsAuthRefresh and awsCredentialExport settings now verify workspace trust before execution
• When these settings come from project or local configuration files, the system checks if the workspace has been explicitly trusted by the user
• If executed before trust confirmation, the system logs a security warning and reports telemetry
• Non-interactive sessions (-p mode) bypass these checks as they don't have interactive trust dialogs
• Evidence: Security check implementation at oH5() at line 438469 and tH5() at line 438512

Why this matters: Prevents malicious projects from triggering AWS credential refresh or export commands that could exfiltrate credentials before the user has reviewed and trusted the workspace.

What: Added support for detecting AWS Marketplace billing and restricting features accordingly

How it works:

• The OAuth profile API now returns an organization.billing_type field
• This value is stored as organizationBillingType in the user's config
• When billing type is "aws_marketplace", certain features are restricted

Details:

• AWS Marketplace customers are excluded from Opus model access, regardless of subscription tier
• The VD() function at line 438734 implements the gating logic
• Billing type is fetched from /api/oauth/profile and persisted across sessions
• Evidence: Field extraction at pC0() at line 397362, feature gating at VD() at line 438734

Limitations: AWS Marketplace customers cannot select the Opus model even with Pro/Max/Enterprise subscriptions.

What: New error handler for API 400 errors caused by tool use concurrency issues

How to recover: When you encounter this error, the system will display:

API Error: 400 due to tool use concurrency issues. Run /rewind to recover the conversation.

Details:

• Detects when tool_use IDs are found without immediately following tool_result blocks
• Provides clear recovery instructions using the existing /rewind command
• The /rewind command restores both code state and conversation to a previous checkpoint
• Evidence: Error handler at bk1() at line 385221

Why this matters: Provides users with actionable recovery steps instead of a generic API error message when tool execution gets out of sync.

What: Removed memoization from credential storage read() methods to prevent stale data

Details:

• Previously, credentials were cached indefinitely using t0() wrapper (lodash memoize)
• After updating credentials, the cache could return old values
• Now every read() call executes fresh credential retrieval
• Affects both macOS Keychain and plaintext storage backends
• All manual cache.clear?.() calls were removed as they're no longer needed
• Evidence: Keychain changes at ly2.read() at line 378584, plaintext changes at PV0.read() at line 378624

Why this matters: Credential updates and deletions now work correctly without returning stale cached values that could cause authentication failures.

What: Removed client-side duplicate UUID checking in favor of server-side validation

Details:

• Previously, the client would skip uploading session entries if their UUID was already fetched
• This client-side cache could become stale in multi-client scenarios
• Now all entries are uploaded, and the server handles deduplication via Last-Uuid headers and 409 conflict detection
• Simplifies retry logic and handles partial fetches more robustly
• Evidence: Function refactor from V8B() at line 397227 to ZPB() at line 436288

Why this matters: Session persistence is more reliable when multiple processes or partial fetch operations are involved.

What: Model selection UI no longer shows rate limit fallback status or reset times

Details:

• Previously displayed "(currently Sonnet)" when users were in rate-limited fallback mode
• Previously showed "Resets at [time]" information
• Function simplified from D3B(model, fallbackActive, resetsAt) to xs2(model)
• The underlying rate limit tracking (maxRateLimitFallbackActive) still exists but is no longer displayed in this UI
• Evidence: Function simplified from D3B() at line 401267 to xs2() at line 392676

Extracted terminal resize detection logic into dedicated p3A() helper function at line 358129. Frame objects now track terminal dimensions (rows, columns) enabling automatic resize detection without explicit boolean parameters. No user-facing changes.

Note: Many variable and function names changed due to minification (approximately 8,390 renames). This is normal for bundled releases and doesn't affect functionality.
