Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 →

Stripping safety caveats hides risk from the user and is a common jailbreak preamble.Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
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 | $0.00084 | $0.01035 |
| Opus 5 | $0.00042 | $0.00517 |
| Sonnet 5 | $0.00017 | $0.00207 |
| Haiku 4.5 | $0.00008 | $0.00103 |
Grade A, and why
power-bi-security 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Power BI Security Skill
Manage row-level security (RLS) and perspectives for Power BI models.
Prerequisites
pipx install pbi-cli-tool
pbi-cli skills install
pbi connect
Security Roles (RLS)
# List all security roles
pbi security-role list
# Get role details
pbi security-role get "Regional Manager"
# Create a new role
pbi security-role create "Regional Manager" \
--description "Restricts data to user's region"
# Delete a role
pbi security-role delete "Regional Manager"
Perspectives
Perspectives control which tables and columns are visible to users:
# List all perspectives
pbi perspective list
# Create a perspective
pbi perspective create "Sales View"
# Delete a perspective
pbi perspective delete "Sales View"
Workflow: Set Up RLS
# 1. Create roles
pbi security-role create "Sales Team" --description "Sales data only"
pbi security-role create "Finance Team" --description "Finance data only"
# 2. Verify roles were created
pbi --json security-role list
# 3. Export full model for version control (includes roles)
pbi database export-tmdl ./model-backup/
Workflow: Create User-Focused Perspectives
# 1. Create perspectives for different audiences
pbi perspective create "Executive Dashboard"
pbi perspective create "Sales Detail"
pbi perspective create "Finance Overview"
# 2. Verify
pbi --json perspective list
Common RLS Patterns
Region-Based Security
Create a role that filters by the authenticated user's region:
pbi security-role create "Region Filter" \
--description "Users see only their region's data"
Then define table permissions with DAX filter expressions in the model (via TMDL or Power BI Desktop).
Department-Based Security
pbi security-role create "Department Filter" \
--description "Users see only their department's data"
Manager Hierarchy
pbi security-role create "Manager View" \
--description "Managers see their direct reports' data"
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-security is a skill published in the GitHub repository julianobarbosa/claude-code-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 84 tokens to every session and 1,035 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 2026-09-03.
