# SCP Plugin Walkthrough
This walkthrough adds a bundled `scp` plugin backed by existing SSH libraries:
This walkthrough covers the bundled `scp` plugin, backed by existing SSH
libraries:
- `paramiko` for SSH and SFTP directory listing
- `scp` for file transfers
The implementation lives in [plugins/scp/__init__.py](plugins/scp/__init__.py).
## What The Plugin Does
## What the plugin does
The SCP plugin mirrors the FTP walkthrough, but on top of SSH:
- `search-file -plugin scp -instance <name> ...` lists remote files and folders over SFTP
- plain `@N` on a folder drills into that directory
- plain `@N` on a file runs `download-file -plugin scp -instance <name> -url ...`
- `@N | add-file -instance ...` downloads first, then ingests the local temp file
- `add-file -plugin scp -instance <name> -path ...` uploads a local file to the configured remote path
- `search-file -plugin scp -instance <name> ...` lists remote files and folders over SFTP.
- plain `@N` on a folder drills into that directory.
- plain `@N` on a file runs `download-file -plugin scp -instance <name> -url ...`.
- `@N | add-file -instance ...` downloads first, then ingests the local temp file.
- `add-file -plugin scp -instance <name> -path ...` uploads a local file to the configured remote path.
## Example config
## Example Config
Add one or more named SCP plugin instances to your config. The current stored
key path remains `provider.scp.<instance>` for legacy compatibility:

Notes:
- `work` and `archive` are instance names; use them with `-instance work` or `-instance archive`.
- `work` and `archive` are instance names.
- `host` and `username` are required for each instance to validate.
- You can use password auth, key auth, or both.
- `base_path` is both the default search root and the default upload directory.
- You can browse configured instances from `.config plugins` in the CLI.
## Search Flow
List the configured base path:
## Search flow
```powershell
search-file -plugin scp -instance work "*"
```
Search by filename:
```powershell
search-file -plugin scp -instance work "invoice"
```
Search another subtree with deeper recursion:
```powershell
search-file -plugin scp -instance work "path:/srv/files/releases depth:2 *.zip"
```
Show only folders:
```powershell
search-file -plugin scp -instance work "path:/srv/files type:folder *"
```

## Download And Add-File Flow
Download into a local folder:
## Download and add-file flow
```powershell

```
Ingest a selected remote file into a configured instance backend:
```powershell
search-file -plugin scp -instance work "report"
@1 | add-file -instance tutorial
```
Why this works:
- file rows advertise `_selection_action` for `download-file`
- `add-file` selection replay inserts that provider download stage before ingest
- the plugin also implements `resolve_pipe_result_download()` for provider-owned SCP rows
- file rows also carry the chosen `instance`, so replay stays bound to the same SSH target
- `add-file` selection replay inserts that plugin download stage before ingest
- the plugin also implements `resolve_pipe_result_download()` for plugin-owned SCP rows

## Upload Flow
Upload a local file to the configured remote `base_path`:
## Upload flow
```powershell
add-file -plugin scp -instance archive -path C:\Media\report.pdf
```
## Implementation Notes
The plugin uses SFTP for directory listing because SCP itself is a transfer protocol, not a browse/search protocol. That split keeps the provider simple:
