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.

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 | $0.00156 | $0.01943 |
| Opus 5 | $0.00078 | $0.00971 |
| Sonnet 5 | $0.00031 | $0.00389 |
| Haiku 4.5 | $0.00016 | $0.00194 |
Grade A, and why
azure-role-selector 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 12d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Azure Role Selector (RBAC Least Privilege)
Azure RBAC grants access through role assignments = security principal + role definition + scope. The goal is least privilege: the minimum role at the narrowest scope that meets the need, assigned to the right kind of principal (group for humans, managed identity for workloads), and time-bound via PIM where it is privileged.
When to use
Choosing the correct role for a user, group, service principal, or managed identity - or reviewing existing assignments for excess privilege.
Do not use this skill for:
- Entra ID directory roles (Global Admin, User Admin, etc.) (use
entra-id) - Microsoft 365 admin roles (use
m365-govern-manage) - Activating privileged roles or designing access reviews (use
azure-pim) - Multicloud entitlement management (use
entra-permissions-management)
Pick the right role family
| Caller needs to... | Look at | Avoid |
|---|---|---|
| Read storage account properties | Control-plane: Reader / Storage Account Contributor | Owner |
| Read blob contents | Data-plane: Storage Blob Data Reader | Reader alone (no data access) |
| Write blob contents | Data-plane: Storage Blob Data Contributor | Owner / Contributor |
| Read Key Vault secrets (RBAC mode) | Data-plane: Key Vault Secrets User | Key Vault Administrator |
| Manage Key Vault itself | Control-plane: Key Vault Contributor | Owner |
| Run an Azure Function with managed identity | Data role on target resource only | Subscription Contributor |
| Delegate role assignment to others | User Access Administrator at narrow scope | Owner |
| Read everything in a subscription | Reader at subscription | Owner / Contributor |
| Manage one resource group only | Contributor at the resource group | Subscription Contributor |
Rule of thumb: Control-plane roles do not automatically grant data-plane access. Reader lets you see a storage account exists; it does not let you read a blob. Pick the right plane explicitly. This is the single most common RBAC mistake.
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.

azure-role-selector is a skill published in the GitHub repository vinayaklatthe/microsoft-security-skills (173 stars, last pushed 2mo ago), licensed MIT. It adds 156 tokens to every session and 1,943 once invoked, about $0.0008 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 2026-08-30.
