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 | $0.00000 | $0.00281 |
| Opus 5 | $0.00000 | $0.00140 |
| Sonnet 5 | $0.00000 | $0.00056 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
lineage-governance 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 11d 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.
What it actually says
Skill: Data Lineage & Governance
When to load
When tracing data origins, assessing impact of schema changes, or managing data catalog.
Lineage in dbt
dbt manifest.json contains full lineage graph.
Use: dbt ls --select +model_name (upstream)
dbt ls --select model_name+ (downstream)
Impact Assessment for Column Change
Before renaming/dropping a column:
1. dbt ls --select model_name+ → list all downstream models
2. Check dashboards/BI tools connected to those models
3. Check ML feature pipelines consuming the column
4. Estimate blast radius: N models, M dashboards affected
Migration approach for breaking changes:
Phase 1: Add new column alongside old column
Phase 2: Migrate downstream consumers to new column (coordinate with owners)
Phase 3: Mark old column deprecated in YAML docs
Phase 4 (after 30 days): Drop old column
Data Catalog Standards
Every table in the warehouse must have:
description: what the table represents (grain, one sentence)owner: team or person responsibledata_classification: PUBLIC / INTERNAL / CONFIDENTIAL / RESTRICTEDsla_freshness: expected update frequency- Column descriptions for all non-obvious fields
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.

lineage-governance is a skill published in the GitHub repository sawrus/agent-guides (17 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 281 tokens. 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.
