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

Game Resolution

All <game> arguments resolve in this order:

Exact ID — full UUID
ID prefix — first N characters (recommend 8+)
Exact name — case-insensitive
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.
