Tiden: connect coding-agent changes to versioned requirements and test evidence
Tiden is an intent-verification tool for teams using coding agents. It keeps specifications versioned beside the code and checks changes against the behaviour requested before the coding session. Its purpose is to make the connection between a requirement and the evidence for it easier to review.
From repository to a reviewed specification
The vendor says Tiden reads a connected GitHub or GitLab repository and tickets from services such as Jira, Linear or Notion, then drafts specifications. A person reviews each draft on a branch before it merges.
Existing Markdown specifications and test suites can be imported. Tiden maps tests to the features they are meant to prove and marks requirements that have no supporting test. The site also describes drafting specification updates after merges, including changes made outside its own workflow.
What a reviewer sees
The published examples show a branch’s requested behaviour alongside test results, and a release view that groups evidence by component. Tiden describes preventing a session from closing with unverified promises, with a person resolving what the loop cannot and making the merge decision.
The demonstration’s coverage figures illustrate that interface. They are not independent evidence that a new customer’s project will have complete requirements, correct tests or no production defects. A green test still needs a meaningful assertion and an accurate specification.
Where it might fit
Franklin’s interpretation is that the strongest trial would use a small change whose intent is easy to misunderstand: a permission boundary, a billing limit or an error response. Compare the original request, the drafted specification and the test that claims to prove it.
Check whether the tool preserves the important exception cases and makes missing evidence visible. That is more informative than counting generated tests. Code review and decisions about acceptable behaviour still need an accountable owner.
