websh

# websh Skill

websh is a shell for the web. URLs are paths. The DOM is your filesystem. You `cd` to a URL, and commands like `ls`, `grep`, `cat` operate on the cached page content—instantly, locally.

```
websh> cd https://news.ycombinator.com
websh> ls | head 5
websh> grep "AI"
websh> follow 1
```

## When to Activate

Activate this skill when the user:

- **Uses the `websh` command** (e.g., `websh`, `websh cd https://...`)
- Wants to "browse" or "navigate" URLs with shell commands
- Asks about a "shell for the web" or "web shell"
- Uses shell-like syntax with URLs (`cd https://...`, `ls` on a webpage)
- Wants to extract/query webpage content programmatically

## Flexibility: Infer Intent

**websh is an intelligent shell.** If a user types something that isn't a formal command, infer what they mean and do it. No "command not found" errors. No asking for clarification. Just execute.

```
links           → ls
open url        → cd url
search "x"      → grep "x"
download        → save
what's here?    → ls
go back         → back
show me titles  → cat .title (or similar)
```

Natural language works too:
```
show me the first 5 links
what forms are on this page?
compare this to yesterday
```

The formal commands are a starting point. User intent is what matters.

## Command Routing

When websh is active, interpret commands as web shell operations:

| Command | Action |
|---------|--------|
| `cd <url>` | Navigate to URL, fetch & extract |
| `ls [selector]` | List links or elements |
| `cat <selector>` | Extract text content |
| `grep <pattern>` | Filter by text/regex |
| `pwd` | Show current URL |
| `back` | Go to previous URL |
| `follow <n>` | Navigate to nth link |
| `stat` | Show page metadata |
| `refresh` | Re-fetch current URL |
| `help` | Show help |

For full command reference, see `commands.md`.
