BI Validation

Driven by ValidationHook.on_end for gen_dashboard runs. The hook passes a SessionTarget containing every DashboardTarget / ChartTarget / DatasetTarget the run delivered. Iterate them and run the checks below.

Target shape

You receive SessionTarget.targets — loop over each entry and dispatch on type:

• dashboard → inspect chart list via get_dashboard / list_charts
• chart → inspect config via get_chart; if supported, run get_chart_data
• dataset → verify fields via get_dataset

Layer A (the builtin hook) has already confirmed each resource exists and is reachable — skip existence checks and focus on config correctness and data presence.

Publish success criteria

A dashboard publish is complete when:

• get_dashboard returns the dashboard
• the expected chart ids / names are present in get_dashboard or list_charts
• every chart can be inspected with get_chart
• supported get_chart_data calls return data or a valid empty result without backend errors
• known values match expected results or tolerances

When these criteria pass, return PASS and stop. Treat additional styling or structural changes as a separate request unless a concrete failing check is present.

Core workflow

For every target in the session:

1. Dashboard targets: call get_dashboard(dashboard_id) to retrieve the chart list. For each chart on the dashboard call get_chart and inspect config (step 2). When get_chart_data is supported, validate data (step 3).
2. Chart targets (standalone or from step 1): verify chart_type, metrics, x_axis, dimensions, dataset_id against the intended design.
3. Data presence: when get_chart_data is supported, call it on every chart to confirm the chart returns data without backend errors. Compare numeric values against expected tolerances when expectations are available.
4. Dataset targets: call get_dataset(dataset_id) to verify schema / SQL / column definitions.
5. Remediation planning:
   • only propose or perform a follow-up change for a specific failed configuration or data check
   • prefer the smallest supported update for fields the platform can modify (title, chart_type, metrics, x_axis, description, platform SQL)
   • for unsupported wiring changes, report the exact mismatch and required follow-up action for the main agent / user
   • if the publish success criteria already pass, return PASS instead of planning follow-up changes
6. Return a compact pass / fail report covering every target.

IMPORTANT: Every chart on the dashboard must pass configuration inspection with get_chart. Data validation with get_chart_data is mandatory when that tool is supported on the active platform. If get_chart_data is unavailable, mark the data check as unsupported / N/A and validate configuration plus reference SQL or known expectations instead.

Platform notes

• Superset: confirm dashboard reachability, chart count, chart type, metric expressions, group-by dimensions, and runtime query success. Use get_chart and get_chart_data for every chart. Compare exact numeric values where expectations are known.
• Grafana: confirm dashboard reachability, panel count, panel type, datasource wiring, and panel SQL against the materialized tables. Use get_chart with dashboard_id for every panel. get_chart_data is not available in Grafana yet, so configuration validation is mandatory and the data check should be reported as unsupported / N/A unless a separate reference query is available.

Configuration inspection checklist (per chart)

When calling get_chart for each chart, verify these fields:

Field	Check
chart_type	Matches intended visualization (bar, pie, big_number, line, table, etc.)
metrics	Correct aggregation expressions (COUNT, SUM, AVG, etc.)
x_axis	Correct column for the horizontal axis (bar/line charts)
dimensions	Correct grouping columns (pie charts, grouped bar charts)
dataset_id	Points to the correct dataset

If title, chart_type, metrics, x_axis, description, or platform-specific SQL is wrong, fix it with update_chart when the tool supports that change. If dimensions, dataset_id, or unsupported wiring is wrong, report the mismatch and the required follow-up action.

Publish verification checklist

After a BI publish, run this checklist:

1. Call get_dashboard to confirm the dashboard is reachable and to retrieve the full chart list.
2. For every chart on the dashboard:
   • call get_chart to inspect configuration (chart_type, metrics, x_axis, dimensions, dataset_id)
   • verify each configuration field matches the intended design
   • if get_chart_data is supported on the active platform, call it to confirm the chart returns data without backend errors
   • verify key numeric values match expected results or tolerances when those expectations are available
   • if get_chart_data is not supported, record the data check as unsupported / N/A and rely on configuration inspection plus reference SQL or known expectations
3. If any chart fails validation:
   • use update_chart only for fields the tool actually supports
   • recreate the chart or panel when the issue is dimensions, dataset_id, or another unsupported wiring change
4. Report both absolute and relative differences when possible.
5. Block rollout when any chart fails configuration or supported data validation.

Do not skip any charts. get_chart_data is required for every chart only on platforms that actually expose it.

Output expectations

For each chart, report:

Column	Description
Chart ID	The chart identifier
Chart Name	Human-readable title
Config Check	PASS if get_chart fields match design, FAIL + reason otherwise
Data Check	PASS if get_chart_data succeeds and expected values match when available; N/A when the platform does not support get_chart_data; FAIL + reason otherwise

Final summary: total charts, passed, failed, overall PASS/FAIL decision.
