      "description": "Estimate a causal effect from a dataset and answer a business question.\n\nProvide exactly one of ``csv`` (CSV text) or ``data`` (list of row objects).\nReturns the full long-form Pulse report (the same answer an email reply\ncontains) as the primary text content and as ``report`` in the structured\nresult, followed by chart PNGs as image content blocks (unless\n``include_charts`` is false). Structured fields: the adjusted effect size\n(``ate``/``effect_size``) with its confidence\ninterval (``ci_low``, ``ci_high``, ``ci_range``), per-channel effects\n(``channels``, keyed by outcome), confidence, and caveats. A ``test_design``\n(how long a spend-cut test would take to confirm the effect, and whether the data\nalready suffices) is included only when the question asks about sample size,\npower, or how long a test would take, or when ``include_test_design`` is true;\notherwise it is null. With ``include_guardian_verdict`` it also returns\n``guardian_verdict`` ``{verdict: pass|caution|hold, reason}``, computed locally.\nAll numbers are deterministic statistics, never LLM-generated.\n\nArgs:\n    question: The business question, e.g. \"Does ad spend drive sales?\".\n    csv: Dataset as CSV text.\n    data: Dataset as a list of row records (alternative to ``csv``).\n    cause: Treatment column (inferred from the question if omitted).\n    effect: Outcome column (inferred if omitted).\n    confounders: Columns to adjust for, in addition to those discovered.\n    outcomes: Several outcome columns, for by-channel effects.\n    time_col: Time column (used for the test-design cadence).\n    include_guardian_verdict: Also return a pass/caution/hold verdict.\n    include_charts: Attach chart images (DAG, effect, trend) as image content.\n    include_test_design: Force the spend-cut test design / sample-size section on\n        (true) or off (false). Omit (null) to include it only when the question\n        asks about sample size, statistical power, or how long a test would take.\n",
