Turn the point of failure into your next improvement. [Markdown](https://flovia.dev/docs/index.md) - [Simulation engine](https://flovia.dev/docs/simulation-engine/): A controlled environment for observing model decisions, tool invocation, and task completion. [Markdown](https://flovia.dev/docs/simulation-engine.md) - [Scenario design](https://flovia.dev/docs/scenario-design/): Translate product use cases into tasks with explicit context, tool contracts, and measurable success criteria. [Markdown](https://flovia.dev/docs/scenario-design.md) - [The agent funnel](https://flovia.dev/docs/agent-funnel/): Seven stages connect product discovery to a completed task, with a specific check at every transition. [Markdown](https://flovia.dev/docs/agent-funnel.md) - [Controlled experiments](https://flovia.dev/docs/controlled-experiments/): Isolate a product-surface change and compare agent behavior under a declared experimental design. [Markdown](https://flovia.dev/docs/controlled-experiments.md) - [Metrics and evidence](https://flovia.dev/docs/metrics-and-evidence/): Read every result with its population, uncertainty, execution conditions, and supporting trace. [Markdown](https://flovia.dev/docs/metrics-and-evidence.md) - [Improve and retest](https://flovia.dev/docs/improvement-loop/): Translate a failed stage into a concrete surface change, then test the same task again. [Markdown](https://flovia.dev/docs/improvement-loop.md) - [Technical FAQ](https://flovia.dev/docs/faq/): Direct answers about the simulation, evaluation methods, and current product interface.
