What

Bots can now show the owner a file they made as a card in the chat, with Open and Save as…, instead of writing its path in the reply.

• share_file MCP tool (crates/botloftd/src/tools/share.rs): 1 to 10 paths. It only accepts files the files panel could already read: the crew's work folder, the bot's own folder, or files the bot wrote. This is the same check files.read uses. Any other path rejects the whole call and tells the bot which file and why. The bot rules and the tool description ask for it when a file is done and when the owner asks for one again.
• save_file_as Tauri command (app/src-tauri/src/save.rs): it opens the system Save As dialog itself and copies the file there, so the page can't write anywhere the owner didn't pick.
• Cards in the chat (app/src/features/chat/SharedFiles.tsx): type icon or image thumbnail, name, extension, size, Open and Save as. Clicking the file opens its preview in the files panel, including an older file the panel list leaves out. In a narrow chat, Save shows only its icon. If the call failed or its answer can't be read, the normal tool line stays.

No DB or protocol change: the cards are drawn from the tool's answer, which the tool chat item already stores. Texts are in all three languages. Spec updated in 5.1, 8.4, 10, 15.1, 15.2, 15.3 and 19.

Checks

• cargo fmt --check, clippy -D warnings, cargo test --workspace, pnpm check (286 tests)
• Real Claude Code (2.1.284, Haiku, dev daemon): asked for a report saved in the work folder. The bot wrote it and called share_file on its own. Then I asked "send me the report again" and it called it again without writing the path. Its first call sent a Windows path with unescaped \, which Claude Code rejects as invalid JSON, and the bot retried correctly. Because of that, the field description now asks for forward slashes. No chat text showed up in the daemon log, even at debug.

Manual test

1. In the real app, ask a bot for a short report saved as a file, then "send me that file again".
2. Both times a card should appear. Click the name and the preview should open in the files panel. Save as… should open the system dialog and copy the file where you pick.

Manual test done in the real Tauri app (pnpm tauri dev, separate data folder, Claude Code 2.1.287, Opus 5.5): asked the lead for a short report saved as a file. It called share_file on its own and the card showed name, MD and size. Clicking the name opened the preview in the files panel. In the narrow chat, Save as showed only its icon and opened the Windows Save As dialog; the saved copy is byte-identical to the bot's file. "Send me that report again" brought a second card without the path in the text. No chat text in the daemon log at debug.
