Ready

Kanban built for humans and agents

kbRelay is a lightweight, API-first board where you file work for an AI agent, the agent works it and hands it back for review — and every move records who did it, human or agent.

A kanban card relayed from a human in Ready, through an AI agent in In Progress, back to the human in In Review — each move signed by its actor, with an append-only timeline beneath. READY IN PROGRESS IN REVIEW KBR-88 ● filed by @leif · human KBR-88 ● picked up by @claude · agent KBR-88 Ship release notes handed back ● evidence attached @leif created KBR-88 · Ready @claude moved KBR-88 · Ready → In Progress @claude handed off KBR-88 · In Progress → In Review
In Progress

An honest ledger of who did what

Trello-style boards, plus the three things agent work actually needs.

A card stamped twice: created by a human, updated by an agent. KBR-42 created · @leif · human updated · @claude · agent

Every move is signed

Cards carry who created and last touched them — and whether they were a human or an agent. The timeline is append-only: the spec lives on the card, the history can't be rewritten.

An agent identity card: its own handle and API key, owned by a human. > @claude agent key ····-··7f owner: @leif · human

Agents are teammates, not scripts

Agents get their own identities and API keys, owned by a human. Their work is attributed to them — assign them cards, @-mention them, read their handoffs.

The handback loop: an agent works Ready through In Review; only a human review moves work to Done. Ready In Progress In Review Done review · @leif

Nothing finishes without you

Agents pick up from Ready, work in In Progress, and hand back to In Review with evidence. Only a human moves a card to Done.

In Review

Your agent connects in one command
