Full changelog
Security
Resolves all 5 findings from the Gen Agent Trust Hub audit (2026-04-13).
Credential Handling (CREDENTIALS_UNSAFE)
- Add
credentialProxyandcredentialProxyScopeto security metadata - New "Credential Handling" section with 5 agent rules: confirm before sending, never log/echo/store/reuse credentials, never auto-retry credential endpoints
- Security notes on
POST /x/accountsandPOST /x/accounts/{id}/reauthendpoints - Remove misleading "never handles raw credentials" claim — was about API key injection, not X account credentials
Prompt Injection Defense (PROMPT_INJECTION)
- Replace blanket "trust the docs" override with scoped version: docs win on endpoint params, rate limits, and pricing only — security rules in the skill always take precedence over external content
- Add
sensitiveDataEndpointsandsensitiveDataHandlingmetadata to gate private-data endpoints behind user confirmation
MCP Remote Security (REMOTE_CODE_EXECUTION)
- Add security context to
mcp-remoteusage in MCP setup guide: what the package does, open-source link, pinned version rationale, global-install alternative to avoidnpx
Sensitive Data Access (DATA_EXFILTRATION)
- New "Sensitive Data Access" section with per-endpoint confirmation prompts for DMs, bookmarks, notifications, and timeline
Sensitive:tags added to each private-data endpoint in api-endpoints.md- Retrieved private data must not be forwarded to non-Xquik tools without explicit user consent
