Google Antigravity CLI 1.1.8

Changelog: Print mode structured output formats, custom JSON schema enforcement, copyOnSelect TUI setting, and compound-command permission improvements

Added structured output formats (json, stream-json) for print mode, support for custom JSON schema validation, enriched tool and subagent payloads, copyOnSelect configuration setting, and improved compound-command permission rules.

Improvements(7)

• Print mode (-p / --print) now supports structured, machine-readable output using the --output-format flag (text (default), json, or stream-json), so headless runs in CI, eval harnesses, and scripts can consume the CLI's output programmatically; these flags are now discoverable in --help.
• Added the stream-json output format: a strongly-typed NDJSON event stream that emits typed init, step_update, and terminal result events with a stable, closed-vocabulary step_type discriminator, so consumers receive progress incrementally instead of waiting for the whole run to finish.
• Added the --json-schema flag to enforce a custom JSON schema on the structured output, accepting either an inline schema string or a path to a schema file; for stream-json the schema applies to the final result event.
• Enriched the structured stream with a tool_info object for each tool call (canonical tool name, parameters, and output) and a subagent_info payload for delegated subagents (including conversation_id and log_uri) so consumers can correlate child trajectories.
• The JSON usage object emitted by json and stream-json now reports token accounting including cache_read_tokens, so non-interactive consumers can attribute prompt-cache hits.
• Added a copyOnSelect setting (default on, toggleable in /settings) that controls whether releasing a mouse text-selection auto-copies it to the system clipboard in the TUI's altscreen rendering mode; disable it to stop the automatic copy on release — useful when the auto-copy is unwanted or corrupts certain payloads.
• Improved compound-command permissions so an exact chained command (such as git fetch && git rebase) can be saved as an allow-always rule and no longer re-prompts on the next identical run.
