  • KiroGraph: How a Local Code Graph Saves 80% of Your AI Tokens

    KiroGraph: How a Local Code Graph Saves 80% of Your AI Tokens
    Jun 17 2026
    Davide de Sio built KiroGraph as a personal side project to stop his AI agent from burning through credits just searching files. It turned into a community-driven, open-source MCP server that gives Kiro (and other AI agents) a semantic map of your codebase — reducing token usage by up to 80%. We dive into the architecture, security, and modules, how everything runs 100% locally, and how the AWS Community shaped the project's roadmap. Key takeaways: • Code graphs vs. grep — Tree-sitter and AST-based graph generation give AI agents a smarter navigation model, eliminating wasteful file searches. • Architecture module — Detects patterns and prevents drift by validating your codebase against its own structural rules. • Security module — Finds exposed secrets and vulnerabilities by tracing the call graph, born from an AWS Summit Milano talk. • Watchman module — Auto-generates Kiro skills from repetitive patterns, building persistent memory for your agent. • 100% local execution — Embeddings run with Nomic and summarization with Gemma 3, no data leaves your machine. • Spec-driven development — Davide built KiroGraph with Kiro itself, using specs to drive the entire development lifecycle. • Portability — Commit the graph to Git and share it across machines and team members. • Community-driven roadmap — CI/CD integration, validation hooks, and container deployment are next.

  • Cutting Through the AI Developer Hype

    Cutting Through the AI Developer Hype
    Jun 10 2026
    An honest, no-filter conversation about where developers actually stand with AI today. Warren Parad — CTO at Authress, AWS Community Builder, and host of Adventures in DevOps — brings a contrarian 'LLM realist' perspective grounded in daily use, while Romain nuances with enterprise customer observations and the data behind the hype. Together they explore why 93% of devs feel productive but only 4% of enterprises see results — and what separates those who benefit from those who don't. Key takeaways: • AI is a multiplier, not a magic wand — The DORA 2025 report confirms AI amplifies your existing processes. If those processes are broken, AI makes them worse faster. • Spec-driven development beats instant responses — Long-form spec-based workflows let you disengage and return, avoiding the 'TikTok-ification' of software engineering where you're always context-switching. • Sub-agent opacity is a real problem — When agents delegate to sub-agents, you lose visibility into why decisions were made. Custom agents with explicit permissions and tool access help contain the blast radius. • Greenfield work is where LLMs struggle most — LLMs excel at refactoring and targeted feature changes where engineers already know the implementation. Open-ended new projects lead to scope creep and unfinished work. • Critical thinking erosion is measurable — Microsoft/Carnegie Mellon research shows knowledge workers self-report reduced cognitive effort when using AI. The long-term implications for engineering judgment are concerning. • Governance first, tools second — Enterprises that succeed with AI spend the first month on governance, AI registries, and codifying best practices before enabling tools across teams. • Software development was never the bottleneck — Unless AI solves handoffs, knowledge management, and organizational alignment, faster coding alone won't compress your roadmap.

  • Why Your Agent Evaluations Will Fail You (and How to Fix Them Before Production)

    Why Your Agent Evaluations Will Fail You (and How to Fix Them Before Production)
    Jun 3 2026
    Anthropic deprecated Sonnet 3.5. Some of Xelix's pipelines migrated smoothly. Others broke — and customers noticed within hours. What separated the two? Evaluation. Paul Solomon and James Price Farr have spent 5+ years building AI systems that process millions of invoices for enterprise customers. In this episode, they share the evaluation-first framework that now saves them every time a model changes, an orchestration layer fails, or an agent picks the wrong tool. Key takeaways: • Evaluation-first, not evaluation-after — Retrofitting evaluation on an agent already in production is painful. Build your eval pipeline before you build the agent. • Monitor tool calls, not just outputs — If the agent isn't selecting the right tools, nothing downstream will be correct. Tool-call monitoring is your leading indicator. • 3 tiers of automation — Not everything needs an agent. Rules-based → single LLM call → agentic system. Pick the simplest tier that solves the problem. • Extended thinking tames token explosion — After migrating to newer, more verbose models, enabling extended thinking (with a budget) moved reasoning out of expensive output tokens and brought costs back under control. • Human-in-the-loop by default — Start with human review on every output, then earn trust toward touchless automation as customers gain confidence. • Pragmatism wins — Use whatever technology works best for the problem. Not every feature needs an LLM. Recorded live at AWS Summit London.
