docs: improve README with quick start steps and SDK usage example

[Reethikaa05]

User description

Summary

This PR updates the README to make it easier for new developers to get started with Julep.
It adds clearer quick start steps, SDK installation examples, and a minimal workflow example for Python.

Changes

• Expanded the "Getting Started" section with exact commands for both Python and Node.js SDK installation.
• Added a minimal code example for defining and running an AI agent with Julep SDK in Python.
• Linked directly to the Quick Start Guide in the official documentation.
• Improved formatting for readability (code blocks, section headers).

Why This Change?

• New contributors can now run their first Julep agent faster without needing to search in external docs.
• Increases developer adoption by making the onboarding smoother.
• Keeps the README aligned with recent updates (SDK support for GPT-5, CLI improvements, etc.).

Example Snippet Added

from julep import Agent

# Create a simple agent
agent = Agent(
    name="hello-agent",
    memory=True,
    tools=[]
)

response = agent.run("Say hello to the world!")
print(response)

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 4 🔵🔵🔵🔵⚪

🧪 PR contains tests

🔒 Security concerns Secrets handling: Several notebooks hardcode placeholder API keys (e.g., JULEP_API_KEY, SPIDER_API_KEY) while others correctly use environment variables (Cloudinary, Browserbase). Replace hardcoded placeholders with environment variable reads and add guidance to avoid committing secrets. Also ensure the social badges/links in notebooks do not expose tokens.

⚡ Recommended focus areas for review Possible Issue The get_story_details tool is configured with a placeholder URL (https://example.com) but later referenced to call HN item endpoints dynamically; ensure the tool definition supports templated per-invocation URLs or update the base URL to avoid 404s. " method: GET\n", " url: \"https://example.com\"\n", " headers:\n", " Content-Type: application/json\n", "\n", Robustness Several evaluate/map steps assume presence of keys like url, top_comments[0], and JSON parsing of model output; add guards for missing fields and try/except around json.loads to prevent execution failures on malformed responses. " $ f'''\n", " Story to analyze:\n", " Title: $ {{ _[\"title\"] }}\n", " URL: $ {{ _[\"url\"] }}\n", " Score: $ {{ _[\"score\"] }}\n", " Content preview: $ {{ _[\"content\"]}}\n", " Top comment: $ {{ _[\"top_comments\"][0][\"text\"] }}\n", "\n", " Return format: \"relevance_score\" from 0 to 100\n", " Return only a JSON object with the relevance score (0-100).\n", " Return ONLY raw JSON without markdown code blocks\n", " '''\n", " unwrap: true\n", "label: score_stories\n", "\n", "# Step 14: Combine original stories with their relevance scores\n", "# Creates tuples of story data and personalization score\n", "- evaluate:\n", " scored_stories: '$ [{{\"story\": steps[\"final_stories_with_comments\"][\"output\"][\"stories_with_comments\"][i], \"relevance_score\": json.loads(steps[\"score_stories\"][\"output\"][i])[\"relevance_score\"]}} for i in range(len(steps[\"score_stories\"][\"output\"]))]'\n", "label: combine_scores\n", Typo/Link In "Related Concepts", the third link text duplicates 'Tasks' and includes a malformed URL suffix; fix the markdown link to 'Tools' with correct URL.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Avoid infinite loop on execution failure Modify the while loop to check for terminal states like "failed" or "cancelled" in addition to "succeeded" to prevent a potential infinite loop. cookbooks/advanced/03-trip-planning-assistant.ipynb [583-587] -while execution.status != "succeeded": +while execution.status not in ["succeeded", "failed", "cancelled"]: time.sleep(5) execution = client.executions.get(execution.id) print("Execution status: ", execution.status) print("-"*50) [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 8 __ Why: This suggestion correctly identifies a potential infinite loop if the execution enters a terminal state other than "succeeded", which is a significant bug in the polling logic.	Medium
	Prevent error on stories without comments Add a check to prevent an IndexError when accessing top_comments for stories that have no comments. cookbooks/advanced/11-hacker-news-personalized-generator.ipynb [339-352] - role: user content: >- $ f''' Story to analyze: Title: $ {{ _["title"] }} URL: $ {{ _["url"] }} Score: $ {{ _["score"] }} Content preview: $ {{ _["content"]}} - Top comment: $ {{ _["top_comments"][0]["text"] }} + Top comment: $ {{ _["top_comments"][0]["text"] if _["top_comments"] else "N/A" }} Return format: "relevance_score" from 0 to 100 Return only a JSON object with the relevance score (0-100). Return ONLY raw JSON without markdown code blocks ''' [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies a potential IndexError if a story has no comments and _["top_comments"][0] is accessed. The proposed fix is robust and prevents the task from failing, which is a significant improvement to the code's reliability.	Medium
	Correct invalid keyword argument Correct the keyword argument from agent to agent_id in the client.sessions.create call to prevent a runtime error. cookbooks/basics/05-RAG-and-Docs.ipynb [17] -"session = client.sessions.create(agent=agent.id, recall=True, recall_options={'mode':'vector','limit':5})\n", +"session = client.sessions.create(agent_id=agent.id, recall=True, recall_options={'mode':'vector','limit':5})\n", [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies a bug in a new example notebook where an incorrect keyword argument agent is used instead of agent_id, which would cause the code to fail.	Medium
	Prevent crashes from missing environment variables Replace os.environ with os.getenv to check for the JULEP_API_KEY and raise a ValueError with a helpful message if it's not set. cookbooks/advanced/03-trip-planning-assistant.ipynb [48] -JULEP_API_KEY = os.environ["JULEP_API_KEY"] +JULEP_API_KEY = os.getenv("JULEP_API_KEY") +if not JULEP_API_KEY: + raise ValueError("JULEP_API_KEY environment variable not set. Please set it to your Julep API key.") [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 7 __ Why: The suggestion improves robustness and user experience by providing a clear error message when a required environment variable is missing, instead of letting the program crash with a KeyError.	Medium
	Add model validation for conditional fields Add a Pydantic model_validator to the GoogleSheetsSetup class to enforce that service_account_json is provided when use_julep_service is False. src/agents-api/agents_api/autogen/Tools.py [1772-1794] +from pydantic import model_validator + class GoogleSheetsSetup(BaseModel): """ Setup parameters for Google Sheets integration """ ... use_julep_service: StrictBool """ Whether to use Julep's built-in Google Sheets service account.

Security	Load API keys from environment Load openweathermap_api_key and brave_api_key from environment variables instead of using hardcoded placeholders to improve security and usability. cookbooks/advanced/03-trip-planning-assistant.ipynb [105-106] -openweathermap_api_key = "YOUR_API_KEY" -brave_api_key = "YOUR_API_KEY" +import os +openweathermap_api_key = os.getenv("OPENWEATHERMAP_API_KEY", "YOUR_API_KEY") +brave_api_key = os.getenv("BRAVE_API_KEY", "YOUR_API_KEY") + [To ensure code accuracy, apply this suggestion manually] Suggestion importance[1-10]: 6 __ Why: The suggestion correctly points out that loading keys from the environment is a better practice for security and usability, especially in an example notebook.
