azure-cosmos-db-py

azure-cosmos-db-py is a skill for Claude Code from satnamrsm/https-github.com-sickn33-antigravity-awesome-skills. It costs 42 tokens per session (1,696 once invoked), scanned A, a copy of azure-cosmos-db-py, MIT.

A Python service pattern for connecting FastAPI web applications to Azure Cosmos DB, Microsoft's globally distributed NoSQL database. It includes production-oriented setup, preferred Azure authentication, local emulator support, and test-driven development (TDD), where tests guide implementation.

In plain words
What is it for?
Use it when building FastAPI routes and services that read or write Cosmos DB data, authenticate users, and test database-related behavior.
Why use it?
It gives a web service a defined way to configure the database for cloud or local use instead of mixing connection details into request-handling code.

Token cost

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.

Security

Grade A, and why

azure-cosmos-db-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 7d 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.

Origin

Cosmos DB Service Implementation

Build production-grade Azure Cosmos DB NoSQL services following clean code, security best practices, and TDD principles.

Installation

pip install azure-cosmos azure-identity

Environment Variables

COSMOS_ENDPOINT=https://<account>.documents.azure.com:443/
COSMOS_DATABASE_NAME=<database-name>
COSMOS_CONTAINER_ID=<container-id>
# For emulator only (not production)
COSMOS_KEY=<emulator-key>

Authentication

DefaultAzureCredential (preferred):

from azure.cosmos import CosmosClient
from azure.identity import DefaultAzureCredential

client = CosmosClient(
    url=os.environ["COSMOS_ENDPOINT"],
    credential=DefaultAzureCredential()
)

Emulator (local development):

from azure.cosmos import CosmosClient

client = CosmosClient(
    url="https://localhost:8081",
    credential=os.environ["COSMOS_KEY"],
    connection_verify=False
)

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.
