01
A deadline that really closes
Every plan carries the moment it ends, at most thirty days out. After that the planbook refuses every remaining step, even one you sign yourself.
Your intent.Your agents.Your control.
Planbook live on mainnet
Tubbi is an AI agent workspace on Robinhood Chain. Write a goal in plain words; four agents read the chain, draft the steps, check them against the limits you set and keep the record. Nothing moves until your own wallet signs each step.

(01)Tubbi
One planbook contract keeps every plan to what you reviewed, from the first step to the last. A goal becomes numbered steps, the steps become hashes, and each one runs only once, only before the deadline, and only with your signature.
Steps in one plan, at most16
Enough for a payroll run or a week of chores, small enough to read in one sitting.
Longest a plan stays open30 d
Every plan ends. After its deadline nothing in it can run, whoever signs.
Admin keys in the planbook0
No owner, no pause, no fee setter, no upgrade path. The rules are constants.
Steps run without your signature0
Agents propose. Your wallet signs every on-chain step, one at a time.
(02)Agents
Tubbi plans, Sift reads, Ward checks and Tally records. They run in your browser as a rule engine, with an optional AI reader on the server; none of them holds a key, and every step they draft waits for you.

Agents, one job each.Planner, reader, guard and recorder. Each step shows which agent proposed it and why.
0 keys
Held by any agent.They can draft and explain. Signing stays in the wallet you connected.
Local
Rules run in your tab.The plan is built and checked in your browser. The optional AI reader only returns intents, which the same rules rebuild.
Exact
Amounts and addresses.Agents never round, guess or fill in an address. Missing details are reported, not invented.
(03)The guard
Pick a situation. The planbook checks the step before anything moves, then records it the moment it runs. Amounts are examples from a two-step plan with a 0.05 ETH cap.
Step 2 of a reviewed plan: 0.01 ETH to the tester. Your wallet signs, the planbook checks the step against what you committed, then forwards the ETH in the same transaction.
Your walletSigns each step
Opens the plan and runs its steps one by one. The only key that counts.
Another walletNot the owner
Any other address. It can read the plan, never run it.
Agent or pageCan only propose
Agents draft steps; they hold no key and cannot call the planbook.

(04)Plan rules
Each rule below is code in the planbook, not a setting on this site. The same nine hold for every plan and every wallet, and nobody can change them after deployment.
02
An ETH ceiling you choose
You set the most ETH the whole plan may send. Each ETH step adds to a running total, and a step that would pass the ceiling reverts.
03
Recipients fixed at review
Each step commits its recipient, token and amount as a hash. Change any of them afterwards and the step stops matching, so it cannot run.
04
One step, one signature
Nothing runs in a batch behind your back. Every step is a separate transaction that your wallet shows you and you approve.
05
Steps that cannot repeat
When a step runs, its bit in the plan is set for good. Sending the same call again is refused, so a double click never pays twice.
06
The reviewed plan, on record
The full plan you read is hashed and stored with it. Anyone holding the plan file can prove it is the version that was opened.
07
Close it whenever you like
The owner can close a plan at any time, before or after its deadline. A closed plan runs nothing, and closing cannot be undone.
08
No admin, no upgrade
The planbook has no owner, no fee, no pause and no proxy. Its rules are constants in the code, the same for every plan and every wallet.
09
Activity anyone can read
Opening a plan, every step and every close emit an event. Tally lists them with links, and any explorer shows the same record.
(05)Your control
Automation usually means handing over a key. Here the agents do the reading and the drafting, and the part that moves money stays with you, one signature per step.

01
Agents propose, your wallet decides
The four agents run as code in your browser tab. They write a plan and explain it; they have no key and no way to send a transaction. Approval always happens in your wallet.
02
Exact approvals, never open-ended
A token step asks your wallet to approve the planbook for exactly that step's amount. There is no unlimited allowance waiting to be used later.
03
Reading is free and harmless
Balances, recipients and prices are read from the chain without a signature. Sift can look as often as you like and still cannot move a coin.
04
No custody, no keys on our side
ETH is forwarded in the same transaction and tokens move straight from you to the recipient. The contract keeps nothing, and this site stores no key.
(06)How a plan runs
Four stages, the same for a single payment or a sixteen-step run.
Say what you want
Type a goal in plain words: who gets what, in which asset, and by when. Add a spending ceiling if you want one; otherwise the plan's own ETH total becomes the cap.
Agents draft the steps
Tubbi turns the goal into numbered steps, Sift reads balances and recipients, and Ward lists every check it ran, with blocks that stop the plan outright.
Open the reviewed plan
Your wallet opens the plan in one transaction: its hash, deadline, ETH cap and one hash per step. Before the planbook is deployed, this is a signed message instead.
Sign, run, record
Run the steps in your order, each with its own signature. Tally keeps the activity log with transaction links until the plan is done, closed or expired.
(07)Contracts
The planbook's source is verified on Blockscout, and anyone can match its code byte for byte against this build with the deployment check. The other rows are the chain's own contracts the workspace reads.
