Example session with https://manicode.ai/

01-about.md

@rootnegativeone referred me to https://manicode.ai/

This is the output from an initial session with it. I used it to create these two commits, including the conventional commit message. The attached session just covers adding xs head. Adding xs get was even more straight forward.

• feat(cli): add xs head command to get head frame for topic
• feat(cli): add xs get command to get frame by id

These were straightforward tasks, but still pretty impressive, particularly how natural it was to amend the existing commit to add the corresponding xs.nu change. I tried to get it to update the README example with the 2 new commands, it failed at that though.

I used 565 credits to create these 2 commits (+ the failed README updates).

If you want to try it, you should grab a referral code: you and which ever link you use will pick up an additional 500 credits per month, fwtm. Pick one of these at random:

xs > examine src/main.rs src/api.rs and src/client.rs: add a new cli command `xs head` which exposes the HeadGet api endoint from the cli

Manicode: Reading the following files...<files>src/main.rs, src/api.rs, src/client.rs, src/nu/commands/mod.rs, src/nu/commands/cas_command.rs, src/nu/commands/remove_command.rs, src/nu/engine.rs, src/nu/util.rs, tests/integration.rs</files>

I'll add a new `head` command to the CLI that uses the existing HeadGet API endpoint. This requires:

1. Adding a new `CommandHead` struct in main.rs
2. Adding a new `head` function in client.rs
3. Updating the `Command` enum in main.rs

Here are the minimal changes needed:

- Editing file: src/main.rs ...

- Editing file: src/client.rs ...

- Editing file: src/main.rs ...

These changes:
1. Add a new `CommandHead` struct with addr and topic parameters
2. Add the `Head` variant to the `Command` enum
3. Add a new `head` client function that calls the existing HeadGet API endpoint
4. Add a new `head` command handler that writes the response to stdout

The command can now be used like:
```bash
xs head localhost:8080 my-topic
```

Applying file changes. Please wait...

- Updated src/main.rs
- Updated src/client.rs
- Updated src/main.rs

xs > review xs.nu, update .head to use this new cli command

Manicode: Reading the following files...<files>xs.nu, src/main.rs, src/client.rs, src/api.rs, src/nu/commands/mod.rs, src/nu/commands/append_command.rs, src/nu/commands/cas_command.rs, src/nu/commands/remove_command.rs, src/nu/engine.rs, src/nu/util.rs, examples/discord-bot/handler-heartbeat.nu, examples/discord-bot/handler-roller.nu, examples/discord-bot/handler-bookmarklet.nu, examples/discord-bot/discord.nu, examples/x-macos-pasteboard/README.md, tests/integration.rs</files>

Looking at xs.nu, I see the current `.head` implementation uses the HTTP API directly. Let's update it to use the new CLI command:

- Editing file: xs.nu ...

This change:
1. Removes the direct HTTP API call
2. Uses the new `xs head` CLI command
3. Preserves the same behavior and return type (JSON parsed output)
4. Uses the existing `store-addr` function for consistency

Applying file changes. Please wait...

- Updated xs.nu
