## Tools (52)

- `analyze_crosstab`: Compute deterministic statistics from a bounded aggregate contingency matrix.
- `analyze_survey`: Run a governed crosstab for an existing hosted project. This task shortcut uses the same deterministic run_table engine and returns a job to poll with get_job.

- `build_tab_book`: Build a reusable tab book for an existing hosted project. This task shortcut uses the same deterministic run_tab_book engine and returns a job to poll with get_job.
- `compare_survey_waves`: Compare compatible saved survey waves. This task shortcut uses the same deterministic compare_waves engine and preserves all comparability warnings.

Queues a hosted job; use get_job to retrieve its result. Obtain actual user approval before calling; do not fabricate approval fields.
- `delete_workspace`: Permanently delete the temporary workspace and all active project, file and job data. This revokes its token.
