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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00110 | $0.01487 |
| Opus 5 | $0.00055 | $0.00744 |
| Sonnet 5 | $0.00022 | $0.00297 |
| Haiku 4.5 | $0.00011 | $0.00149 |
Grade A, and why
power-bi-filters 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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Power BI Filters Skill
Add and manage filters on PBIR report pages and visuals. Filters are stored
in the filterConfig section of page.json (page-level) or visual.json
(visual-level). No Power BI Desktop connection is needed.
Listing Filters
# List all filters on a page
pbi filters list --page page_abc123
# List filters on a specific visual
pbi filters list --page page_abc123 --visual visual_def456
Returns each filter's name, type, field, and scope (page or visual).
Categorical Filters
Include or exclude specific values from a column:
# Include only East and West regions
pbi filters add-categorical --page page1 \
--table Sales --column Region \
--values "East" "West"
The filter appears in the page's filterConfig.filters array. Power BI
evaluates it as an IN-list against the specified column.
TopN Filters
Show only the top (or bottom) N items ranked by a measure:
# Top 10 products by revenue
pbi filters add-topn --page page1 \
--table Product --column Name \
--n 10 \
--order-by-table Sales --order-by-column Revenue
# Bottom 5 by quantity (ascending)
pbi filters add-topn --page page1 \
--table Product --column Name \
--n 5 \
--order-by-table Sales --order-by-column Quantity \
--direction Bottom
The --table and --column define which dimension to filter (the rows you
want to keep). The --order-by-table and --order-by-column define the
measure used for ranking. These can be different tables -- for example,
filtering Product names by Sales revenue.
Direction defaults to Top (descending -- highest N). Use --direction Bottom
for ascending (lowest N).
Relative Date Filters
Filter by a rolling window relative to today:
# Last 30 days
pbi filters add-relative-date --page page1 \
--table Calendar --column Date \
--period days --count 30 --direction last
# Next 7 days
pbi filters add-relative-date --page page1 \
--table Calendar --column Date \
--period days --count 7 --direction next
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.

power-bi-filters is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 110 tokens to every session and 1,487 once invoked, about $0.0006 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.
