Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

auditing-warehouse-view-health scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Auditing data warehouse view health

This skill produces a project-wide audit of materialized views (materialized saved queries) in the data warehouse — which ones are failing, and which are materialized but unused. Use it when the user wants a summary of view health, not a deep-dive on one failure.

The same underlying endpoint (data-warehouse-data-health-issues-retrieve) also reports source, sync, batch-export, and transformation issues. Source and sync health is covered by auditing-warehouse-source-health. Destinations (batch exports) and transformations are owned by other products — surface them if they appear, but route them to the relevant team rather than diagnosing here.

When to use this skill

  • "Which of my views are broken?" / "Why is this materialized view failing?"
  • "Are any of my materialized views wasting compute?"
  • Reviewing view health after a HogQL or schema change
  • Dashboards backed by materialized views are stale or erroring

Available tools

Tool Purpose
data-warehouse-data-health-issues-retrieve One-shot: all failed/degraded items across the whole pipeline
view-list All saved queries / materialized views with status and latest_error
view-run-history Run history for a specific materialized view

Filter the data-health-issues results to the materialized_view type for this audit. Use view-list when you need more than the active-failure summary (non-failing views, materialization flags, last-queried info) and view-run-history to see the run trail for a specific view.

What counts as a view "issue"

From the data-health endpoint, this audit cares about one of the five categories:

type Trigger Typical urgency
materialized_view DataWarehouseSavedQuery.is_materialized=true, status=Failed Medium

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
