Python: [Samples][Python] durabletask/ samples missing .env.example files

[leestott]

Description

None of the 7 durabletask/ samples (01-07) provide a .env.example or .env.template file. Users must read the README or dig through source code to discover which environment variables are needed.

This is inconsistent with the foundry-hosted-agents/ samples which consistently include .env.example files.

Affected Samples

• python/samples/04-hosting/durabletask/01_single_agent/ — needs FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL
• python/samples/04-hosting/durabletask/02_multi_agent/ — needs AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_MODEL
• python/samples/04-hosting/durabletask/03_single_agent_streaming/ — needs FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL, REDIS_CONNECTION_STRING
• python/samples/04-hosting/durabletask/04_single_agent_orchestration_chaining/ — needs FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL
• python/samples/04-hosting/durabletask/05_multi_agent_orchestration_concurrency/ — needs FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL
• python/samples/04-hosting/durabletask/06_multi_agent_orchestration_conditionals/ — needs AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_MODEL
• python/samples/04-hosting/durabletask/07_single_agent_orchestration_hitl/ — needs FOUNDRY_PROJECT_ENDPOINT, FOUNDRY_MODEL

Suggested Fix

Add a .env.example file to each sample listing the required environment variables with placeholder values, matching the pattern used in foundry-hosted-agents/.

Example:

FOUNDRY_PROJECT_ENDPOINT="https://your-project.services.ai.azure.com/api/projects/your-project"
FOUNDRY_MODEL="your-deployment-name"

Environment

• Python 3.13.13, Windows 11
