Anthropic's Mythos surfaces vulnerabilities at AI scale. A coding agent equipped with Moderne closes every one with a deterministic recipe, distributed across every repository in parallel

Every Mythos-discovered flaw in a kernel, browser engine, or shared OSS library becomes a published CVE in your scanner queue. The backlog multiplies by orders of magnitude before you act on any of it.
LLM-based remediation produces partial fixes. The agent declares victory while you re-prompt it all evening trying to confirm coverage you can never quite pin down. Vulnerability fixes have to be complete to count.
An attacker only needs to find one instance of a vulnerability. A defender has to close every instance, or the business stays exposed. Coding agents alone are built for the attacker’s job. Without a recipe, there’s no way to confirm every occurrence has been closed.
Fixing one CVE across two thousand repositories with raw inference pays for the same reasoning two thousand times over, which doesn't scale. A recipe is written once and runs everywhere, so the work is amortized.
For end-of-life frameworks like older Spring, the "just upgrade" path is a multi-quarter migration. Mythos doesn't grant that runway, so backpatching into the version you run may be the only path that fits the window.
CISOs will be asked "what is our exposure to the latest Mythos disclosure?" within hours of each release. Without a deterministic remediation pipeline with an audit trail, the honest answer is "we don't know."
In an IDE, you trust rename and extract-method refactorings because they're deterministic. OpenRewrite takes that determinism outside the editor and makes it programmatic. Each recipe is a verifiable program that runs the same way every time, against any repository in your portfolio
The source of the determinism. A type-attributed, semantically complete representation of your code that supports interprocedural, field-sensitive taint analysis. Without the LST, an agent's fix is a probabilistic guess. With it, the agent has a verifiable blueprint to execute.
One recipe runs across thousands of repositories in parallel. The unit economics of fixing one CVE across 2,000 repos should not be 2,000 times the cost of fixing one. With Moderne, it isn't.
Connect any coding agent (Copilot, Cursor, Windsurf, Devin, Claude Code) to Moderne via MCP. With LST-based tools in hand, the agent both authors and executes deterministic recipes. Agent-agnostic by design.
For end-of-life frameworks you can't upgrade fast enough, Moderne backports the security fix to the version you're running and distributes it. No forced migration. No runway loss.
Every recipe run is deterministic and produces a verifiable record of what changed, where, and why. The board-ready answer to "what is our exposure" is a query against the same pipeline that did the remediation.
