A set of instructions for changing the internal networking and session setup of the Contentstack iOS Content Delivery SDK. The SDK is a software library that lets iOS apps retrieve content from Contentstack.

It is for editing network configuration, URL handling, caching, retries, and Apple session management in this SDK.

It helps changes to configuration, request handling, retries, and sessions follow the SDK's existing behavior.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.00562
Opus 5	$0.00015	$0.00281
Sonnet 5	$0.00006	$0.00112
Haiku 4.5	$0.00003	$0.00056

Security

Grade A, and why

framework 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 3d 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.

Framework – Contentstack iOS CDA SDK

Use this skill when changing configuration, URL/session behavior, or the internal HTTP stack (not the high-level CDA object model).

When to use

Modifying Config properties or how Stack applies config to base URLs and headers.
Changing CSIOCoreHTTPNetworking request building, response handling, or retry loops.
Changing CSURLSessionManager, session configuration, delegate wiring, or operation queues.
Adjusting CSIOAPIURLs, CSIOConstants, caching (CSIOURLCache), or internal extensions (NSObject+Extensions).

Instructions

Config and Stack

Config exposes delivery-related options (host, region, branch, session delegate, early access). Preserve default behavior expected by existing apps when changing initialization or defaults.
Stack ties config to the internal network object; keep reference lifetimes and teardown (cancelAllRequestsOfStack:) coherent.

HTTP session layer

CSURLSessionManager wraps NSURLSession with success/failure blocks and delegate callbacks. Changes here affect all CDA traffic—verify timeouts, TLS behavior, and background vs foreground assumptions.
Do not fragment session usage: new CDA calls should use the same stack/session path as existing ones unless intentionally designing a new client.

Retry and resilience

Retry is implemented in CSIOCoreHTTPNetworking (e.g. handling of transient errors with bounded retries and backoff). When adjusting retry conditions or counts, document behavior and consider alignment with other Contentstack CDA SDKs’ retry policies where applicable.

Errors

Propagate NSError and API error payloads through the same paths used today so higher layers (Stack, Entry, Query, etc.) remain consistent.

Key files (indicative)

Config / stack wiring: Config.m, Stack.m
HTTP: CSIOCoreHTTPNetworking.m, CSIOCoreHTTPNetworking.h
Session: CSURLSessionManager.m, CSURLSessionManager.h, CSURLSessionDelegate.h
URLs / constants: CSIOAPIURLs.m, CSIOConstants.m

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.

framework is a skill published in the GitHub repository contentstack/contentstack-ios (3 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 562 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
