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 | $0.00029 | $0.01213 |
| Opus 5.5 | $0.00012 | $0.00485 |
| Sonnet 5.5 | $0.00006 | $0.00243 |
| Haiku 4.5 | $0.00003 | $0.00121 |
Grade A, and why
azure-identity-py 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 1mo 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
94% identical to azure-identity-py — 11 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 SDK for Python
Authentication library for Azure SDK clients using Microsoft Entra ID (formerly Azure AD).
Installation
pip install azure-identity
Environment Variables
# Service Principal (for production/CI)
AZURE_TENANT_ID=<your-tenant-id>
AZURE_CLIENT_ID=<your-client-id>
AZURE_CLIENT_SECRET=<your-client-secret>
# User-assigned Managed Identity (optional)
AZURE_CLIENT_ID=<managed-identity-client-id>
DefaultAzureCredential
The recommended credential for most scenarios. Tries multiple authentication methods in order:
from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient
# Works in local dev AND production without code changes
credential = DefaultAzureCredential()
client = BlobServiceClient(
account_url="https://<account>.blob.core.windows.net",
credential=credential
)
Credential Chain Order
| Order | Credential | Environment |
|---|---|---|
| 1 | EnvironmentCredential | CI/CD, containers |
| 2 | WorkloadIdentityCredential | Kubernetes |
| 3 | ManagedIdentityCredential | Azure VMs, App Service, Functions |
| 4 | SharedTokenCacheCredential | Windows only |
| 5 | VisualStudioCodeCredential | VS Code with Azure extension |
| 6 | AzureCliCredential | az login |
| 7 | AzurePowerShellCredential | Connect-AzAccount |
| 8 | AzureDeveloperCliCredential | azd auth login |
Customizing DefaultAzureCredential
# Exclude credentials you don't need
credential = DefaultAzureCredential(
exclude_environment_credential=True,
exclude_shared_token_cache_credential=True,
managed_identity_client_id="<user-assigned-mi-client-id>" # For user-assigned MI
)
# Enable interactive browser (disabled by default)
credential = DefaultAzureCredential(
exclude_interactive_browser_credential=False
)
Specific Credential Types
ManagedIdentityCredential
For Azure-hosted resources (VMs, App Service, Functions, AKS):
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-identity-py is a skill published in the GitHub repository Ghosteken/agent-harness (4 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 1,213 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 94% identical to azure-identity-py, differing in 11 lines, and is treated as a copy.
