using-vit

1. Overview

vit is a Bun CLI for social software capabilities. Agents use it to initialize projects, follow accounts, skim caps from followed accounts, and ship new caps. Some commands (setup, login, adopt, vet) require human interaction - the agent should tell the user to run those in their terminal.

2. Prerequisites

Dependency chain:

setup → login → init → follow → skim/ship

setup

and

login

are human-only. The agent starts at

init

. Use

vit doctor

to check setup and beacon status before running discovery or shipping commands.

3. Agent Workflow

Run
```
vit init
```
to initialize
```
.vit/
```
directory (derives beacon from git remotes).
Run
```
vit follow <handle>
```
to follow accounts whose caps you want to see.
Run
```
vit skim --json
```
to read caps from followed accounts filtered by beacon.

Run

vit ship <text> --title <t> --description <d> --ref <ref>

to publish a cap.

Handoffs:

If no DID is configured, tell the user to run
```
vit login <handle>
```
.
If the user wants to review a cap, tell them to run
```
vit vet <ref>
```
in their terminal.

5. Commands the Agent Must NOT Run

These commands require human interaction. Tell the user exactly what to run:

```
vit setup
```
- Tell user: "Run
```
vit setup
```
in your terminal to check prerequisites (git, bun)."
```
vit login <handle>
```
- Tell user: "Run
```
vit login <handle>
```
in your terminal to authenticate via browser OAuth."
```
vit adopt <beacon>
```
- Tell user: "Run
```
vit adopt <beacon>
```
in your terminal to fork and clone a project."
```
vit vet <ref>
```
- Tell user: "Run
```
vit vet <ref>
```
in your terminal to review a cap." Mention
```
--trust
```
flag for approving.

These are human-only because they call

requireNotAgent()

(or require browser interaction for login) and will fail or be inappropriate when run by an agent.

6. Error Handling

Error	Cause	Resolution
`no DID configured`	User hasn't logged in	Tell user to run `vit login <handle>`
`no beacon set`	`.vit/` not initialized or no beacon	Run `vit init`
`no followings` / empty skim results	No accounts followed	Run `vit follow <handle>`
Session errors (deleted/expired)	OAuth session invalid	Tell user to run `vit login <handle> --reset`
Invalid ref format	Ref doesn't match `^[a-z]+-[a-z]+-[a-z]+$`	Use three lowercase words joined by hyphens
