Designing a Context Compression Sub-Agent in AgentKit 2.0 — A Production Pipeline That Stops Long-Running Tasks From Drowning in Their Own History
When you run an AgentKit 2.0 agent for hours inside Antigravity, response time and accuracy degrade together as the conversation history balloons. This premium guide walks through a production-grade dynamic compression sub-agent — schema, prompt, integration hooks, and an A/B evaluation harness — so you can decide rollout based on numbers, not gut feel.
Antigravity Agent Product Launch Blueprint — A 90-Day Roadmap to Ship and Sell an AgentKit 2.0 Product as an Indie Developer
A complete 90-day roadmap for turning an AgentKit 2.0 build into a product an indie developer can actually sell — covering product design, production-grade implementation, distribution channel choice, Stripe integration, launch prep, and the operational discipline that decides whether an agent business survives.
Building Multi-Agent Systems with AgentKit 2.0 in Antigravity — A Production Implementation Guide
AgentKit 2.0 dropped the barrier to multi-agent systems sharply. After implementing three different agent-coordination patterns in Antigravity, here's the design playbook covering decisions, traps, and production operation.
Five Paths to Sell AI Agents Built on AgentKit 2.0 — How Indie Developers Should Pick a Distribution Channel
AgentKit 2.0 lets a solo developer ship a real, useful AI agent. The hard question is where to sell it. This article walks through five distribution paths — marketplaces, direct sales, SaaS embedding, productized consulting, and subscription agents — with the trade-offs that matter.
