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 | $0.00038 | $0.02563 |
| Opus 5 | $0.00019 | $0.01282 |
| Sonnet 5 | $0.00008 | $0.00513 |
| Haiku 4.5 | $0.00004 | $0.00256 |
Grade A, and why
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 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

Security Skill
This skill helps implement Row-Level Security (RLS) and Object-Level Security (OLS) for Power BI semantic models.
When to Use This Skill
- Restricting data access by user/role
- Implementing dynamic security based on user identity
- Creating multi-tenant data models
- Protecting sensitive columns with OLS
- Setting up manager/hierarchy security
- Testing security configurations
Security Types
| Type | Controls | Use Case |
|---|---|---|
| RLS (Row-Level Security) | Which rows users can see | Regional sales reps see only their region |
| OLS (Object-Level Security) | Which columns/tables users can see | Hide salary column from non-HR users |
Row-Level Security (RLS)
TMDL Syntax
role 'Sales Representatives'
modelPermission: read
lineageTag: <guid>
tablePermission Sales = 'Sales'[Region] = USERPRINCIPALNAME()
Role Structure
role 'RoleName'
modelPermission: read
description: 'Description of who this role is for'
lineageTag: <guid>
tablePermission TableName = <DAX filter expression>
tablePermission AnotherTable = <DAX filter expression>
Model Permissions
| Permission | Description |
|---|---|
read |
Can read data (standard for RLS) |
administrator |
Full access (no filtering) |
none |
No access |
Common RLS Patterns
Static Role (Fixed Filter)
/// Role for West region users
role 'West Region'
modelPermission: read
lineageTag: {{guid}}
tablePermission Sales = 'Sales'[Region] = "West"
Dynamic Security (User Identity)
/// Each user sees only their own data
role 'User Data'
modelPermission: read
lineageTag: {{guid}}
tablePermission Sales =
'Sales'[User Email] = USERPRINCIPALNAME()
Security Table Lookup
/// Users mapped to regions in a security table
role 'Region Security'
modelPermission: read
lineageTag: {{guid}}
tablePermission Sales =
CONTAINS(
FILTER(
'User Region Mapping',
'User Region Mapping'[User Email] = USERPRINCIPALNAME()
),
'User Region Mapping'[Region], 'Sales'[Region]
)
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

security is a skill published in the GitHub repository kpbray/power-bi-agent-skills (9 stars, last pushed 7mo ago), licensed MIT. It adds 38 tokens to every session and 2,563 once invoked, about $0.0002 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 2026-08-31.
