    "title": "Your AI Agent Starts Every Session Like a New Hire - Killian Carlsen-Phelan, Sonar",
    "one_liner": "Sonar's pitch: a coding agent starts every session like a new hire. Sonar Vortex is a plugin that loads SonarQube's project knowledge (architecture map, coding guidelines, approved libraries) into the agent before it writes code. It then runs deterministic checks on every edit, so issues are fixed in the loop instead of at the PR.",
    "summary": "Killian Carlsen-Phelan says agents start each session without knowing your project's conventions or architecture. So they burn tokens searching the repo, copy the codebase's existing issues, and add new ones that only turn up at PR review. Sonar Vortex plugs into coding agents such as Claude Code, Codex and Antigravity. It reuses what the existing SonarQube CI scan has learned to guide the agent before it writes anything, and it verifies every edit deterministically. A recorded Java demo shows Vortex catching a temp file created without explicit permissions. It then rejects Claude's first fix, which relied on a Java default, until the permissions are set explicitly.",
    "key_points": [
      "Problem framing: every new agent session is like a new hire who doesn't know the project's conventions, coding guidelines or architecture rules. It has to search for context, which is 'a roll of the dice' and costs time and tokens, and it tends to copy issues already in the codebase.",
      "Sonar surveyed over 1,100 developers: 96% do not fully trust AI-generated code, but only 48% fully verify it before pushing.",
      "Vortex has two phases, 'guide' and 'verify'. Before writing, the agent pulls architecture guidelines, approved libraries, coding standards and a map of how the code connects (e.g. 'Sonar context navigation' and 'Sonar context guidelines get language is Java'). Every edit the agent makes with its own tools triggers a quick check. Before ending its turn, the agent is told to run a deeper check for security issues and cross-file data flow.",
      "Vortex reuses what the CI SonarQube scan already learned, so each check covers only the changed file while still knowing about the rest of the codebase. It is built on Sonar's CLI and MCP tools, and configurable MCP clients cover custom or open-source agents.",
      "Claimed results: 36% fewer tokens on average (especially when refactoring existing codebases), a 44% reduction in production outages among users, and a very low false-positive rate.",
      "Demo: Claude unzipped a GC log file into a reused temp file, with a test, in under 2 minutes. Vortex returned six findings: two on new lines and four on pre-existing code. Only new code must be fixed; pre-existing issues are just reported. The security finding was a log in a shared default temp folder with no explicit read permissions. Claude's first fix relied on a Java default that is already owner-only on Mac and Linux, but Vortex flagged it again because the rule requires permissions to be set explicitly.",
      "The session starts with the Sonar CLI, the hook system and secrets detection all detected automatically, with no Sonar instructions pasted into the prompt. Secrets detection prevents leaks into GitHub and into agent context memories.",
      "Deterministic vs AI review: having an agent check itself is 'one of the least reliable ways' to catch issues, and AI reviewers miss things and hallucinate. A deterministic layer gives the same result on every run, which makes it governable and compliant. Sonar positions it as stacked on top of AI coding and alongside an AI review tool (transcribed as 'Guitar')."
    ],
    "takeaways": [
      "Give the agent context and steering up front: architecture map, coding guidelines, approved libraries and custom team rules. Outside model choice, the speaker calls this the biggest lever on agent performance.",
      "Move verification into the agent loop with hooks that run on every file edit and a deeper check before the turn ends, rather than catching issues at the PR.",
      "Use deterministic analysis, not agent self-review, as the trust layer, especially in automated or 'factory' agent workflows.",
      "Make the agent fix issues in the code it just wrote, but only surface pre-existing issues, so sessions don't get noisy.",
      "Turn on secrets detection in agent sessions so credentials don't leak into GitHub or the agent's context and memory."
