Local evidence verification for AI-assisted work

When AI says “done,” ask what proves it.

See which checks ran, what they found, and what remains unknown. HyoDo reuses your project's tests and linters. Its guiding Hyo (孝) principle is that technology should respect people's time and choices, and carry its share of the burden instead of passing it back to them. Missing evidence is UNOBSERVED: there is not enough evidence to call it a pass or a failure. HyoDo does not run or authorize agents. People decide what to do.

Evidence graph Prototype

Rows show participants, columns show steps, and cells show events. A solid line links a causal parent, a dashed line points to supporting evidence, and a red stub marks a broken link. ALLOW, ASK, DENY, and UNOBSERVED are policy-evaluation outputs, not execution permissions.

This interactive example uses sample data only; nothing is uploaded. A local HyoDo dashboard can show the same relationships from a real event ledger.

Tab to a cell to inspect its record. Press Escape to clear the panel without losing focus. Shift+Tab moves to the previous cell.

What HyoDo offers today

Latest published release: HyoDo 4.22.3. Source version: HyoDo 4.22.3. A shipped adapter is not evidence that a host is connected right now. See how current status is measured.

FeatureStatusWhat that means
Local project checksAvailableRun the checks you configure and keep a local record of what happened.
Evidence graphAvailableShows how events connect; the example on this page uses sample data.
Codex and Cursor adaptersIncludedThe adapters are shipped; we have not verified a live connection.
Information-flow reportingObserver onlyReports data movement; it does not control what an agent can do.
Hosted ChatGPT connectorNot liveOnly the connector contract is documented; there is no hosted service.
Automatic task routingResearchHyoDo does not route tasks to a particular agent or workflow.
Shared rework reportsNot builtHyoDo does not collect or upload reports about rework.

For people who use AI to build software

A confident “done” is not proof. HyoDo shows which configured checks ran, what they found, and what remains unknown—so you can decide what to trust.

Why HyoDo →

For developers

Reuse the checks your project already has. HyoDo keeps their commands in one gate list and reports what ran; it does not replace the tools themselves.

Quickstart →

For teams that must show evidence

See which checks ran, what passed or failed, and what was not measured. HyoDo records those results but does not approve a merge or deployment.
