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 | $0.00041 | $0.02081 |
| Opus 5 | $0.00020 | $0.01040 |
| Sonnet 5 | $0.00008 | $0.00416 |
| Haiku 4.5 | $0.00004 | $0.00208 |
Grade A, and why
azure-identity-dotnet 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.
This is a copy
89% identical to azure-identity-dotnet — 63 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Azure.Identity (.NET)
Authentication library for Azure SDK clients using Microsoft Entra ID (formerly Azure AD).
Installation
dotnet add package Azure.Identity
# For ASP.NET Core
dotnet add package Microsoft.Extensions.Azure
# For brokered authentication (Windows)
dotnet add package Azure.Identity.Broker
Current Versions: Stable v1.17.1, Preview v1.18.0-beta.2
Environment Variables
Service Principal with Secret
AZURE_CLIENT_ID=<application-client-id>
AZURE_TENANT_ID=<directory-tenant-id>
AZURE_CLIENT_SECRET=<client-secret-value>
Service Principal with Certificate
AZURE_CLIENT_ID=<application-client-id>
AZURE_TENANT_ID=<directory-tenant-id>
AZURE_CLIENT_CERTIFICATE_PATH=<path-to-pfx-or-pem>
AZURE_CLIENT_CERTIFICATE_PASSWORD=<certificate-password> # Optional
Managed Identity
AZURE_CLIENT_ID=<user-assigned-managed-identity-client-id> # Only for user-assigned
DefaultAzureCredential
The recommended credential for most scenarios. Tries multiple authentication methods in order:
| Order | Credential | Enabled by Default |
|---|---|---|
| 1 | EnvironmentCredential | Yes |
| 2 | WorkloadIdentityCredential | Yes |
| 3 | ManagedIdentityCredential | Yes |
| 4 | VisualStudioCredential | Yes |
| 5 | VisualStudioCodeCredential | Yes |
| 6 | AzureCliCredential | Yes |
| 7 | AzurePowerShellCredential | Yes |
| 8 | AzureDeveloperCliCredential | Yes |
| 9 | InteractiveBrowserCredential | No |
Basic Usage
using Azure.Identity;
using Azure.Storage.Blobs;
var credential = new DefaultAzureCredential();
var blobClient = new BlobServiceClient(
new Uri("https://myaccount.blob.core.windows.net"),
credential);
ASP.NET Core with Dependency Injection
using Azure.Identity;
using Microsoft.Extensions.Azure;
builder.Services.AddAzureClients(clientBuilder =>
{
clientBuilder.AddBlobServiceClient(
new Uri("https://myaccount.blob.core.windows.net"));
clientBuilder.AddSecretClient(
new Uri("https://myvault.vault.azure.net"));
// Uses DefaultAzureCredential by default
clientBuilder.UseCredential(new DefaultAzureCredential());
});
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.
