# Story 420: loc for a specified file — bot command and web UI slash command

## User Story

As a developer, I want to send `loc <filepath>` to the bot or use it as a slash command in the web UI to see the line count for a specific file, so I can quickly check how large a file is without leaving my workflow.

## Acceptance Criteria

- [ ] loc <filepath> returns the line count for the specified file
- [ ] Relative paths are resolved against the project root
- [ ] If the file does not exist, returns a clear error
- [ ] Works from all transports (Matrix, WhatsApp, Slack)
- [ ] Works as a slash command in the web UI
- [ ] loc with no argument retains existing behavior (top files by line count)
- [ ] Exposed as an MCP tool so agents can query file line counts programmatically

## Out of Scope

- TBD
