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 | $0.00145 | $0.02939 |
| Opus 5 | $0.00072 | $0.01470 |
| Sonnet 5 | $0.00029 | $0.00588 |
| Haiku 4.5 | $0.00015 | $0.00294 |
Grade A, and why
power-bi 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.

Power BI Development Skill
End-to-end Power BI project development using the PBIP (Power BI Project) format — the git-friendly, text-based format for version-controlled Power BI solutions.
When This Skill Applies
- Creating or modifying Power BI semantic models (TMDL files)
- Writing or debugging Power Query (M) expressions (.pq files)
- Authoring DAX measures
- Designing star schema data models
- Publishing reports to Power BI Service
- Configuring scheduled refresh and data gateways
- Troubleshooting PBI connectors (especially Azure Cost Management / EA)
- Working with any .tmdl, .pq, .pbip, .pbir, .pbism files

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.
- 8d ago First seen · 233 lines · 145 tokens per session scan A 9a260ec34a9d
power-bi is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 145 tokens to every session and 2,939 once invoked, about $0.0007 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.
