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 | $0.00081 | $0.01160 |
| Opus 5 | $0.00041 | $0.00580 |
| Sonnet 5 | $0.00016 | $0.00232 |
| Haiku 4.5 | $0.00008 | $0.00116 |
Grade A, and why
testing-a-datavault4dbt-project 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Testing a datavault4dbt project
Turn the Primary-Key and Foreign-Key assumptions of Data Vault 2 into dbt tests. In DV2 these are soft constraints — implemented as dbt tests that warn (and let you investigate) rather than hard database constraints that would silently drop "bad and ugly" raw data you still want to capture.
Default to soft constraints (dbt tests). Only use hard database constraints if you accept the risk of losing non-conforming raw data and have an Error Mart to catch it.
Where these tests live
Add data_tests in the model's YAML file (colocated with the .sql). Generic tests unique and
not_null are built in; relationships covers FK integrity. For multi-column uniqueness (satellites)
use dbt_utils.unique_combination_of_columns (add the dbt_utils package) or an equivalent.
The technical test matrix
| Entity | Column(s) | Test |
|---|---|---|
| Hub | hashkey | not_null, unique |
| Link | link hashkey | not_null, unique |
| Link | each foreign hashkey | relationships to its connected hub's hashkey |
| Satellite v0 | hashkey + load date | unique combination of columns |
| Satellite v0 | hashkey | relationships to parent hub/link |
| Non-historized link | link hashkey | not_null, unique |
| Non-historized link | each foreign hashkey | relationships to connected hubs |
| Non-historized satellite v0 | hashkey | not_null, unique, relationships to parent NH-link |
| Multi-active satellite v0 | hashkey + load date + multi-active key(s) | unique combination of columns |
| Multi-active satellite v0 | hashkey | relationships to parent hub/link |
| Record-tracking satellite | hashkey + load date | unique combination of columns |
| Record-tracking satellite | hashkey | relationships to parent hub/link |
| Reference hub | reference key(s) | unique, not_null |
| Reference satellite v0 | reference key(s) + load date | unique combination of columns |

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.

testing-a-datavault4dbt-project is a skill published in the GitHub repository ScalefreeCOM/datavault4dbt-agent-skills (22 stars, last pushed 13d ago), licensed Apache-2.0. It adds 81 tokens to every session and 1,160 once invoked, about $0.0004 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 2026-08-30.
