Detecting No-Progress in AI Agents Without Reading Promptshttps://signallayerlabs.github.io/Marginal/blog/detecting-no-progress-without-reading-prompts/2026-08-19T13:14:00+02:002026-08-19T13:14:00+02:00A technical model for detecting AI coding-agent no-progress loops from action identity, outcomes, state and evidence—without treating raw prompts as required telemetry. Why an AI Agent Governor Should Start Powerlesshttps://signallayerlabs.github.io/Marginal/blog/why-ai-agent-governor-should-start-powerless/2026-08-19T13:14:00+02:002026-08-19T13:14:00+02:00Installing an AI agent governor should not automatically grant blocking authority. A safer runtime model starts in Shadow Mode and earns narrow enforcement from local evidence.
