3. #3# Shared To-Do Board > ⚠️ **Experimental — generated with no human supervision.** This realm was > produced automatically by an MCP-driven agent to exercise the gno MCP server > and tooling, and to generate test content for gno compilers, linters and > formatters. **Not audited. Not for production.** Full context & folder README: > [r/moul/x/daily](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md) --- An on-chain, shared to-do list realm for the gno.land **sapphire** testnet (gno 0.9). Anyone can add an item to the board; each item records the caller's address as its author, and can be toggled open/done or removed. `Render` shows the board as Markdown checkboxes with live open/done counts, newest item first. - **Realm path:** `gno.land/r/REPLACE_ADDR/todos` (replace `REPLACE_ADDR` with your deploy address) ## Exported transactions | Function | Effect | |---|---| | `Add(text string) int` | Adds an item authored by the caller, returns its id | | `Toggle(id int)` | Flips an item between open and done | | `Remove(id int)` | Deletes an item | All three are gno 0.9 crossing functions (`cur realm` first parameter) and must be invoked with `cross(cur)` from another realm, or directly via `MsgCall`. ## Example calls ```sh # Add an item (returns the new id) gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/todos" \ -func Add -args "buy milk" -gas-fee 1000000ugnot -gas-wanted 2000000 \ -broadcast -chainid sapphire-1 -remote <rpc> mykey # Mark item #3 done (toggle) gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/todos" \ -func Toggle -args 3 -gas-fee 1000000ugnot -gas-wanted 2000000 \ -broadcast -chainid sapphire-1 -remote <rpc> mykey # Remove item #3 gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/todos" \ -func Remove -args 3 -gas-fee 1000000ugnot -gas-wanted 2000000 \ -broadcast -chainid sapphire-1 -remote <rpc> mykey ``` ## Example render output ```markdown # Shared To-Do Board 2 open · 1 done · 3 total - [ ] #3 walk dog (g1abc…) - [x] #2 buy milk (g1abc…) - [ ] #1 write realm (g1def…) ``` <!-- BEGIN GNOCONTRACTS FOOTER (generated by `make readmes`; do not edit below) --> --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
