Azure Cosmos Py

Azure Cosmos DB SDK for Python

Overview

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/azure-cosmos-py from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

Azure Cosmos DB SDK for Python Client library for Azure Cosmos DB NoSQL API — globally distributed, multi-model database.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Environment Variables, Authentication, Client Hierarchy, Queries, Partition Keys, Throughput.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Azure Cosmos DB SDK for Python (NoSQL API). Use for document CRUD, queries, containers, and globally distributed data.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. bash pip install azure-cosmos azure-identity ### Setup Database and Container python # Get or create database database = client.createdatabaseifnotexists(id="mydb") # Get or create container with partition key container = database.createcontainerifnotexists( id="mycontainer", partitionkey=PartitionKey(path="/category") ) # Get existing database = client.getdatabaseclient("mydb") container = database.getcontainerclient("mycontainer") ### Create Item python item = { "id": "item-001", # Required: unique within partition "category": "electronics", # Partition key value "name": "Laptop", "price": 999.99, "tags": ["computer", "portable"] } created = container.createitem(body=item) print(f"Created: {created['id']}") ### Read Item python # Read requires id AND partition key item = container.readitem( item="item-001", partitionkey="electronics" ) print(f"Name: {item['name']}") ### Update Item (Replace) python item = container.readitem(item="item-001", partitionkey="electronics") item["price"] = 899.99 item["onsale"] = True updated = container.replaceitem(item=item["id"], body=item) ### Upsert Item python # Create if not exists, replace if exists item = { "id": "item-002", "category": "electronics", "name": "Tablet", "price": 499.99 } result = container.upsertitem(body=item) ### Delete Item python container.deleteitem( item="item-001", partition_key="electronics" )
2. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
3. Read the overview and provenance files before loading any copied upstream support files.
4. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
5. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
6. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
7. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.

Imported: Core Workflow

Setup Database and Container

# Get or create database
database = client.create_database_if_not_exists(id="mydb")

# Get or create container with partition key
container = database.create_container_if_not_exists(
    id="mycontainer",
    partition_key=PartitionKey(path="/category")
)

# Get existing
database = client.get_database_client("mydb")
container = database.get_container_client("mycontainer")

Create Item

item = {
    "id": "item-001",           # Required: unique within partition
    "category": "electronics",   # Partition key value
    "name": "Laptop",
    "price": 999.99,
    "tags": ["computer", "portable"]
}

created = container.create_item(body=item)
print(f"Created: {created['id']}")

Read Item

# Read requires id AND partition key
item = container.read_item(
    item="item-001",
    partition_key="electronics"
)
print(f"Name: {item['name']}")

Update Item (Replace)

item = container.read_item(item="item-001", partition_key="electronics")
item["price"] = 899.99
item["on_sale"] = True

updated = container.replace_item(item=item["id"], body=item)

Upsert Item

# Create if not exists, replace if exists
item = {
    "id": "item-002",
    "category": "electronics",
    "name": "Tablet",
    "price": 499.99
}

result = container.upsert_item(body=item)

Delete Item

container.delete_item(
    item="item-001",
    partition_key="electronics"
)

Examples

Example 1: Ask for the upstream workflow directly

Use @azure-cosmos-py to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @azure-cosmos-py against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @azure-cosmos-py for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @azure-cosmos-py using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Always specify partition key for point reads and queries
• Use parameterized queries to prevent injection and improve caching
• Avoid cross-partition queries when possible
• Use upsert_item for idempotent writes
• Use async client for high-throughput scenarios
• Design partition key for even data distribution
• Use read_item instead of query for single document retrieval

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/azure-cosmos-py, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Cross-Partition Query

# Cross-partition (more expensive, use sparingly)
