Tiden

Verifies that coding agents deliver what they promised by tying every spec to a passing test.

Overview

Tiden is intent verification for coding agents, built by the team behind the Qase test-management platform. It reads the codebase, writes each spec down and keeps those specs versioned in the repository next to the code, flagging any spec that no test proves.

Each agent task becomes a list of promises, and the agent session cannot close until every promise has a passing test. Branches and releases get a verdict showing what was promised and what proves it, and production errors can be traced back to a release. Tiden runs beside existing coding agents such as Claude Code, Cursor, Copilot and Codex. It offers Starter and Team plans with a 14-day trial.
