[DOCS] Agent SDK docs missing `CLAUDE_CODE_ACCOUNT_UUID`, `CLAUDE_CODE_USER_EMAIL`, and `CLAUDE_CODE_ORGANIZATION_UUID` env vars

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://platform.claude.com/docs/en/agent-sdk/python

Section/Topic

SDK caller identity/account metadata configuration and related environment variables.

Current Documentation

Agent SDK input docs currently only provide a generic user field:

user | str | None | None | User identifier

Monitoring docs describe telemetry attributes:

organization.id — Organization UUID (when authenticated) user.account_uuid — Account UUID (when authenticated) user.email — User email address (when authenticated via OAuth)

No documentation defines CLAUDE_CODE_ACCOUNT_UUID, CLAUDE_CODE_USER_EMAIL, or CLAUDE_CODE_ORGANIZATION_UUID.

What's Wrong or Missing?

Release v2.1.51 added:

CLAUDE_CODE_ACCOUNT_UUID, CLAUDE_CODE_USER_EMAIL, and CLAUDE_CODE_ORGANIZATION_UUID environment variables for SDK callers to provide account info synchronously...

These new variables are not documented in SDK or settings docs, leaving users without:

• Accepted values/format
• Where to set them (CLI env vs SDK process env)
• Precedence relative to auth-derived metadata
• Privacy/telemetry implications

Suggested Improvement

Add a "Caller identity environment variables" section in Agent SDK docs and settings docs with:

• Definitions for all three variables
• End-to-end SDK examples (Python and TypeScript)
• Precedence and fallback behavior
• Security/privacy guidance for handling PII values

Impact

Medium - Makes feature difficult to understand
