Why AI Agents Need JSON Even More After the OpenAI Agents API: Harness, Tool Calling, JSON Schema
Hosting the harness is not hosting the contract. After the Agents API, JSON Schema is the layer you still hold.
Why Does AI-Generated JSON Fail JSON.parse()? Complete Causes and Fixes
Looks like JSON still throws. Strip fences first, prefer Structured Output, and do not start with a regex repair.
AI Agent Security Guide: Malicious JSON, Prompt Injection, Tool Calling, and Structured-Data Risks
A jailbroken chatbot says the wrong sentence. A jailbroken agent fires a tool call. Tighten JSON Schema before you tune the prompt.
MCP vs Skills vs Tools vs Subagents: What Differs, and How the 2026 AI Agent Stack Is Changing
Tools are the call contract; MCP is the cross-process socket; Skills are how-to playbooks; Subagents isolate context. Mix the layers and you debug the wrong one.

What can stay on device, stays. What must go to the cloud uses PCC — not a normal LLM API. Leaks usually start in the JSON fields you put on an App Action.
Why iPhone 18 Became an AI Phone: Apple Intelligence, Siri AI, and AI Agents
Not a chatbot skin. 12GB RAM, Siri AI, and App Actions turn the iPhone 18 Pro lineup into a system-level AI agent — with JSON Schema as the contract.
What Is AI Structured Output? Why GPT, Gemini, and Claude All Constrain JSON
Structured Output is not the prompt “please return JSON.” GPT, Gemini, and Claude now block illegal tokens with a JSON Schema so a program can parse the final reply.
What Is MCP? Model Context Protocol, JSON-RPC, AI Agents, and LLM Tool Calling
MCP is not another Function Calling. It is JSON-RPC between Host and tool processes; the model still uses Tool Calling, with JSON Schema as the contract.
What Is a 1M Token Context Window? Long Context Uses and GPT vs Claude vs Gemini
1M tokens is not “a million Chinese characters.” GPT-5.5, Claude 4.6/4.8, and Gemini 3.7: advertised window, effective retrieval, and the bill for stuffing large JSON.
