17-dx-delivery-sdk

A coding guide for Contentstack’s Delivery SDK, a TypeScript library for reading content and assets from Contentstack.

In plain words
What is it for?
Use it for entries, assets, references, filters, sorting, pagination, locales, typed fetching, Live Preview, Visual Builder, and server-rendered previews.
Why use it?
It helps avoid incorrect method names, query options, and call order when writing SDK code.

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.

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

17-dx-delivery-sdk 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 2d 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.

Description

Help agents write correct, production-ready TypeScript using @contentstack/delivery-sdk for Contentstack entries, assets, references, filtering, sorting, pagination, locale, Live Preview, and Visual Builder support. Verify SDK behavior against the Delivery SDK Spec when method names, options, or chain order matter.

When to Use

Use when a user asks for Contentstack Delivery SDK code, query examples, helper functions, SDK setup, stack initialization, reference inclusion, filtering, sorting, pagination, typed entry fetching, asset fetching, Live Preview setup, Visual Builder support, SSR preview handling, or debugging SDK query chains.

User Problem

Users need current, correct Contentstack Delivery SDK code with the right method names, chain order, and query patterns. The skill should prevent subtle SDK mistakes and default to production-ready TypeScript.

Success Criteria

  • Uses current @contentstack/delivery-sdk method names and correct chain order.
  • Verifies API details against the Delivery SDK Spec when behavior is uncertain.
  • Produces TypeScript-first examples with safe environment-based credentials.
  • Handles references, filters, sorting, pagination, field selection, assets, locale, and Live Preview correctly.
  • Flags or avoids common mistakes such as wrong query methods, missing pagination, or shared SSR Live Preview stacks.

Expected Inputs

  • Content type UID
  • Entry UID or asset UID when applicable
  • Field UIDs for filters, sorting, selection, or references
  • Locale when localized content is needed
  • Desired return shape or helper function behavior
  • SSR or Visual Builder context when Live Preview is involved

Expected Outputs

  • TypeScript code snippets
  • Reusable helper functions
  • Correct SDK query chains
  • Live Preview or SSR-safe stack setup
  • Debugging guidance for incorrect Contentstack SDK usage

Example User Requests

  • Write a Contentstack Delivery SDK query for blog posts with author references included.
  • Show me the correct TypeScript setup for Contentstack Live Preview in Next.js SSR.
  • Fix this Contentstack query chain; it is not returning the right entries.
  • Create a helper to fetch entries by URL with pagination and typing.
  • How do I fetch assets and filter by content type in @contentstack/delivery-sdk?

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.
