LunaBox CLI Skill

LunaBox is a Windows visual novel / galgame library manager. The lunacli binary provides CLI access to the full library — listing, querying, launching, and backing up games. This skill enables AI agents to operate LunaBox on behalf of users.

Prerequisites

• The lunacli binary must be in the system PATH or at a known absolute path.
• LunaBox must have games already added via the GUI application.
• Output is UTF-8 and may contain CJK characters (Japanese game titles) and Unicode symbols.

Commands

List Games

Show every game in the user's library.

lunacli list

Output is an ASCII table with columns: Short ID (8-char prefix), Status Icon, Name.

Status icons:

• · Not Started
• ▶ Playing
• ✓ Completed
• ○ On Hold
• ✗ Dropped

Parsing: Each data row follows │ <8-char-id> │ <icon> <name> │. Extract the ID and name from each row.

Game Details

Show comprehensive metadata for a single game.

lunacli detail <game>

Output is key-value pairs (one per line, split on first :): Name, ID, Status, Source, Company, Launch Path, Save Path, Process Name, Use Locale Emulator, Use Magpie, Created At, Cached At, Summary.

Start a Game

Launch a game from the library.

lunacli start <game>
lunacli start <game> --le          # With Locale Emulator (Japanese locale)
lunacli start <game> --magpie      # With Magpie (resolution upscaling)
lunacli start <game> --le --magpie # Both

Flags:

• --le / -l: Force Locale Emulator. Requires configured LE path.
• --magpie / -m: Force Magpie upscaling. Requires configured Magpie path.

On success: Game started successfully! followed by Recording play duration....

Important: If multiple games match, the command lists candidates and fails. Retry with a more specific ID or full name.

Backup Saves

Create a local backup of a game's save files.

lunacli backup --game <game>
lunacli backup -g <game>

On success, output includes: ✓ Game save backup created successfully!, Game name, File name, Size, Path.

Version

lunacli version

Returns version, git commit, build time, build mode.

Protocol Management

lunacli protocol register [--exe <path>]
lunacli protocol unregister

Register or unregister the lunabox:// URL scheme. Typically not needed for agent use.

Game Resolution

All <game> arguments resolve in this order:

1. Exact ID — full UUID
2. ID prefix — first N characters (recommend 8+)
3. Exact name — case-insensitive
4. Fuzzy name — substring match, case-insensitive

Multiple matches produce a candidate list and an error. Retry with a more specific query.

Workflow Patterns

Refer to references/workflows.md for detailed workflow examples covering: game recommendation, launching the currently-playing game, pre-route backup, and play-status queries.

Error Handling

Common errors (non-zero exit code, message on stderr):

Error message	Cause
no game found matching: <query>	No match at all
please use a longer ID prefix to match exactly one game	Ambiguous ID prefix
please use the exact game ID or refine your search	Ambiguous name match
Locale Emulator path is not configured	LE not set up in LunaBox settings
Magpie path is not configured	Magpie not set up in LunaBox settings

Safety Notes

• Only start and backup have side effects. list, detail, and version are read-only.
• Do not run multiple start commands simultaneously — one game at a time.
• Always confirm with the user before running start (launches a program) or backup (writes to disk).
• When recommending games, run lunacli list first, then lunacli detail on candidates to read summaries before making recommendations.

System Prompt Snippet

To integrate LunaBox into a bot framework, add the following to the bot's system prompt:

You have access to the user's LunaBox game library via the `lunacli` CLI tool.

Available actions:
- `lunacli list` — Show all games (ID, status, name)
- `lunacli detail <game>` — Show game metadata and synopsis
- `lunacli start <game> [--le] [--magpie]` — Launch a game
- `lunacli backup -g <game>` — Backup game saves

Game queries accept: full ID, 8-char ID prefix, or game name (fuzzy match).
Status: · not started, ▶ playing, ✓ completed, ○ on hold, ✗ dropped.

Use these tools to help the user manage their visual novel library: browse games,
get recommendations, check play status, launch games, and backup saves.
Always run `lunacli list` first if you need to know what games the user has.
