Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00099 | $0.01231 |
| Opus 5 | $0.00049 | $0.00616 |
| Sonnet 5 | $0.00020 | $0.00246 |
| Haiku 4.5 | $0.00010 | $0.00123 |
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.

auditing-warehouse-view-health is a skill published in the GitHub repository PostHog/posthog-foss (715 stars, last pushed today), licensed MIT. It adds 99 tokens to every session and 1,231 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
