Note

Medium Risk
Changes 1Password fill matching semantics and WebMCP invoke failure/retry expectations for integrators; the CLI workflow shift affects release automation timing and diff scope, not runtime SDK code paths in this diff.

Overview
Release 0.139.0 bumps version metadata and documents two API-facing behavior changes from the changelog.

1Password fill (vaultitem.go): docs now say the 1Password extension decides whether an approved login matches the page (Kernel’s origin gate is gone). entry_id is described as needed when several entries are approved and the page origin does not identify exactly one—not when multiple entries merely share an origin.

WebMCP invoke (browserwebmcp.go): docs add tool_page_unloaded when the tool’s page is reloaded/replaced without the tool responding, alongside outcome_unknown. Both outcomes are not retried and set X-Should-Retry: false because side effects may have occurred. InvokeRequestParam.Input is documented as 4 MiB (was 1 MiB) after JSON serialization.

The Update CLI Coverage workflow now runs on release: published instead of push to main, uses full git history and the published release tag for the SDK version, and bases the SDK diff on origin/main’s go.mod so cumulative CLI update branches stay accurate. Agent instructions were tightened so coverage reports and diffs span everything since CLI main’s SDK version and the agent does not add CLI surface beyond what this SDK release exposes.
