//! [Model Context Protocol][mcp] server exposed at the `/mcp` endpoint.
//!
//! Wraps every [`Command`] the [`crate::background_thread`] dispatcher
//! understands as an MCP **tool**, plus a handful of MCP **resources**
//! (game lists, enum dumps, examples, reference docs) and **prompts** for
//! common workflows ("open and inspect a pack", "edit a DB table",
//! "manage dependencies", …). Each MCP client gets its own dedicated
//! [`Session`] and [`McpServer`] — same isolation guarantees as the
//! WebSocket clients.
//!
//! Each tool call:
//!
//! 1. Translates its `*Args` payload into a [`Command`] and ships it
//!    through the session's
//!    [`background_loop`](crate::background_thread::background_loop) via
//!    the `send_and_respond!` helper.
//! 2. Wraps the resulting [`Response`] back into a [`CallToolResult`].
//!
//! The `*Args` structs are the canonical schema for every tool. Their
//! `JsonSchema` derive is what `rmcp` ships to clients to advertise tool
//! arguments, so docstrings on individual fields show up directly in MCP
//! tool listings.
//!
//! [mcp]: https://modelcontextprotocol.io/
//! [`Session`]: crate::session::Session
//! [`CallToolResult`]: rmcp::model::CallToolResult

This is the MCP server for RPFM (Rusted PackFile Manager), a tool for modding Total War games by \
Creative Assembly. It lets you read, edit, create, and manage PackFiles (.pack) — the archive \
format used by all modern Total War titles.

## Key Concepts

- **PackFile**: An archive containing game data files (DB tables, localisation, textures, models, etc.). \
  Mods are distributed as PackFiles.
- **pack_key**: When you open one or more PackFiles, each gets a unique key string. Use `list_open_packs` \
  to discover available keys. Most tools require a `pack_key` parameter.
- **DataSource**: Where data lives — `\"PackFile\"` (the user's mod), `\"GameFiles\"` (vanilla game data), \
  `\"ParentFiles\"` (dependency mods), `\"AssKitFiles\"` (Assembly Kit data), `\"ExternalFile\"` (disk file).
- **ContainerPath**: A path inside a pack — either `{\"File\": \"db/land_units_tables/my_table\"}` or \
  `{\"Folder\": \"db/land_units_tables\"}`. Use an empty string for root folder.

## Required Initialization Sequence

1. **Set the game** — Call `set_game_selected` with the game key (e.g. `\"warhammer_3\"`) and \
   `rebuild_dependencies: true`. This loads schemas and vanilla data.
2. **Open a pack** — Call `open_packfiles` with filesystem path(s). Note the returned pack key(s).
3. **Verify schema** — Call `is_schema_loaded`; if false, call `update_schemas` first.

## Supported Games

Valid game keys: `pharaoh_dynasties`, `pharaoh`, `warhammer_3`, `troy`, `three_kingdoms`, \
`warhammer_2`, `warhammer`, `thrones_of_britannia`, `attila`, `rome_2`, `shogun_2`, `napoleon`, \
`empire`, `arena`.

## Common File Path Conventions

- DB tables: `db/<table_name>/<file_name>` (e.g. `db/land_units_tables/my_mod`)
- Localisation: `text/db/<file_name>.loc`
- Scripts: `script/<path>.lua`
- Images: `ui/<path>.png`

## Pack File Types (PFHFileType)

`\"Boot\"`, `\"Release\"`, `\"Patch\"`, `\"Mod\"` (default for mods), `\"Movie\"`.

## Compression Formats

`\"None\"` (default), `\"Lzma1\"` (legacy), `\"Lz4\"` (WH3 6.2+), `\"Zstd\"` (WH3 6.2+).

## Creating New Files (NewFile)

- DB table: `{\"DB\": [\"file_name\", \"table_name\", version]}` — e.g. `{\"DB\": [\"my_mod\", \"land_units_tables\", 0]}`
- Loc file: `{\"Loc\": \"file_name\"}`
- Text file: `{\"Text\": [\"file_name\", \"Plain\"]}` — formats: `\"Plain\"`, `\"Html\"`, `\"Xml\"`, `\"Lua\"`, `\"Cpp\"`, `\"Json\"`, `\"Markdown\"`, `\"Smithy\"`
- AnimPack: `{\"AnimPack\": \"file_name\"}`
- PortraitSettings: `{\"PortraitSettings\": [\"file_name\", version, [[\"entry_key\", \"entry_value\"]]]}`
- VMD: `{\"VMD\": \"file_name\"}`
- WSModel: `{\"WSModel\": \"file_name\"}`

## Resources

Use `resources/list` and `resources/read` to browse reference data: valid enum values, game lists, \
and example JSON payloads without needing tool calls.

## Responses

All tool responses are JSON-serialized. On failure, an error message is returned instead of the expected data.

RPFM MCP Server Initialization Guide
=====================================

Before you can work with PackFiles, you must initialize the server session:

Step 1: Set the game
    Call: set_game_selected(game_name: \"warhammer_3\", rebuild_dependencies: true)
    This loads the correct schemas and vanilla game data for the selected title.
    Valid game keys: pharaoh_dynasties, pharaoh, warhammer_3, troy, three_kingdoms,
    warhammer_2, warhammer, thrones_of_britannia, attila, rome_2, shogun_2,
    napoleon, empire, arena.

Step 2: Verify schema is loaded
    Call: is_schema_loaded()
    If it returns false, call update_schemas() to download the latest schemas.

Step 3: Open a PackFile
    Call: open_packfiles(paths: [\"/path/to/my_mod.pack\"])
    The response returns pack info including the pack_key you'll use for all
    subsequent operations.

Step 4: Verify dependencies (optional but recommended)
    Call: is_there_a_dependency_database(value: true)
    If false, call generate_dependencies_cache() to build the dependency database.

After initialization, use list_open_packs() to see all open pack keys at any time.

Total War PackFile Path Conventions
====================================

Files inside PackFiles follow specific path conventions:

DB Tables:
    db/<table_name>/<file_name>
    Example: db/land_units_tables/my_mod
    Example: db/unit_stats_land_tables/custom_units

Localisation (Loc) files:
    text/db/<file_name>.loc
    text/<file_name>.loc
    Example: text/db/my_mod.loc

Scripts:
    script/<path>.lua
    script/campaign/mod/<script_name>.lua
    Example: script/campaign/mod/my_mod_script.lua

UI Images:
    ui/<path>.png
    Path may vary depending on the purpose of the image.

Models and Animations:
    variantmeshes/<path>
    animations/<path>
    Example: variantmeshes/wh_variantmodels/hu1/my_unit/my_unit.wsmodel

Audio:
    audio/<path>.bnk

Maps:
    terrain/tiles/battle/<map_name>/

You are an assistant helping the user inspect a Total War PackFile using the RPFM MCP server.

Follow these steps in order:

1. **Open the pack** – Call `open_packfiles` with the filesystem path(s) the user provides.
   The response contains one or more pack keys; remember them for subsequent calls.

2. **Select the game** – Call `set_game_selected` with the correct game key (e.g. `\"warhammer_3\"`)
   and `rebuild_dependencies: true` so that schemas and dependency data are loaded.

3. **List pack contents** – Call `open_pack_info` with the pack key to get the full file tree.
   Present the tree to the user in a readable format.

4. **Decode specific files** – When the user asks about a file, call `decode_packed_file` with the
   pack key, the internal path (e.g. `\"db/land_units_tables/my_table\"`), and
   `source: \"PackFile\"`. The decoded JSON will contain the table rows, schema, etc.

5. **Inspect metadata** – Use `get_pack_settings`, `get_pack_file_name`, or
   `get_dependency_pack_files_list` to answer questions about the pack itself.

Important notes:
- Always call `list_open_packs` if you are unsure which pack key to use.
- If a file fails to decode, check `is_schema_loaded`; if false, call `update_schemas` first.
- When done, optionally call `close_pack` to free resources.

You are an assistant helping the user edit a DB table inside a Total War PackFile.

Workflow:

1. **Open the pack** – `open_packfiles` → note the `pack_key`.
2. **Set the game** – `set_game_selected` with `rebuild_dependencies: true`.
3. **Decode the table** – `decode_packed_file` with the DB path
   (e.g. `\"db/unit_stats_land_tables/my_table\"`) and `source: \"PackFile\"`.
   The response is an `RFileDecoded` JSON containing the table data and definition.
4. **Modify rows** – Edit the decoded JSON: add, remove, or change rows/cells.
   Each row is typically a list of `DecodedData` values matching the table's
   fields processed list (retrievable via the `FieldsProcessed` message).
5. **Save back** – Call `save_packed_file_from_view` with the pack key, the same path,
   and the modified `RFileDecoded` JSON as the `data` parameter.
6. **Save the pack** – Call `save_packfile` (or `save_pack_as` for a new path).

Tips:
- Use `get_table_definition_from_dependency_pack_file` to see the expected column schema.
- Use `get_reference_data_from_definition` to discover valid values for referenced columns.
- After saving, you can run `diagnostics_check` to validate the pack.

2. **Create the pack** – `new_pack` returns a new empty pack and its pack key.

3. **Set pack type** – `set_pack_file_type` to `\"Mod\"` (the standard type for mods).

4. **Add DB tables** – For each table you need:
   a. Call `new_packed_file` with the pack key, the path (e.g. `\"db/land_units_tables/my_mod\"`),
      and the `new_file` JSON set to `\"DB\"` with the table name.
   b. Decode, edit, and save as described in the `edit_db_table` workflow.

5. **Add Loc files** – For localisation:
   a. `new_packed_file` with path `\"text/db/my_mod.loc\"` and `new_file` set to `\"Loc\"`.
   b. Decode, add key/value rows, and save.

6. **Add other files** – Use `add_packed_files` to import assets from disk (images, models, etc.).

7. **Save the pack** – `save_pack_as` to write the final `.pack` file to disk.

Optional steps:
- `initialize_my_mod_folder` to set up a mod development folder with IDE support.
- `optimize_pack_file` to strip unchanged rows that match vanilla data.
- `diagnostics_check` to validate everything before release.

   If it returns false, call `generate_dependencies_cache` first.

3. **Browse vanilla tables** – `get_table_list_from_dependency_pack_file` returns all
   DB table names from the vanilla game files.

4. **Read vanilla data** – `get_tables_from_dependencies` with a table name to get
   all rows from vanilla for that table.

5. **Get definitions** – `get_table_definition_from_dependency_pack_file` to get the
   schema definition for any table.

6. **Import from vanilla** – `import_dependencies_to_open_pack_file` to copy specific
   files from vanilla into your mod pack.

7. **Open CA packs** – `load_all_ca_pack_files` opens all vanilla packs as one merged
   read-only pack for full browsing.

8. **Cross-source lookups** – `get_rfiles_from_all_sources` retrieves files by path
   from PackFile, GameFiles, and ParentFiles simultaneously.

Tips:
- Use `get_packed_files_names_starting_with_path_from_all_sources` to discover files

2. **Get the full schema** – `get_schema` returns the entire schema object.

3. **Inspect a table definition** – `definitions_by_table_name` with a table name
   returns all known versions. Use `definition_by_table_name_and_version` for a
   specific version.

4. **See processed fields** – `fields_processed` takes a Definition JSON and returns
   fields with bitwise expansion and enum conversions applied (useful for display).

5. **Find referencing columns** – `referencing_columns_for_definition` shows which
   other tables reference a given table's columns.

6. **Patch a definition** – To customise column metadata (descriptions, references,
   default values) without modifying the upstream schema:
   a. Build a `HashMap<String, DefinitionPatch>` with your changes.
   b. Call `save_local_schema_patch` to persist it locally.
   c. Use `remove_local_schema_patches_for_table` or
      `remove_local_schema_patches_for_table_and_field` to undo patches.

7. **Import patches** – `import_schema_patch` applies a patch from another source.

8. **Update from Assembly Kit** – `update_current_schema_from_asskit` merges
   definition data from the game's Assembly Kit into the loaded schema.

9. **Save the schema** – `save_schema` writes the current in-memory schema to disk.

You are an assistant helping the user troubleshoot common RPFM and PackFile issues.

## Common Issues and Solutions

### 1. Schema not loaded
**Symptom**: Files fail to decode, or `decode_packed_file` returns raw data.
**Solution**:
- Call `is_schema_loaded()` – if false, call `update_schemas()`.
- Make sure `set_game_selected` was called with `rebuild_dependencies: true`.

### 2. Dependencies not available
**Symptom**: References show as invalid, diagnostics report missing keys.
**Solution**:
- Call `is_there_a_dependency_database(true)` – if false, call `generate_dependencies_cache()`.
- Ensure the game path is configured correctly in settings.

### 3. Pack won't save
**Symptom**: `save_packfile` returns an error.
**Solution**:
- Check if the file is read-only or locked by another process.
- Try `save_pack_as` to a different path.
- As a last resort, use `clean_and_save_pack_as` to recover from corruption.

### 4. Table version mismatch
**Symptom**: Table data looks wrong or has missing columns after a game update.
**Solution**:
- Call `update_schemas()` to get the latest table definitions.
- Use `update_table` to migrate the table to the current version.
- Check `get_table_definition_from_dependency_pack_file` for the expected schema.

### 5. Wrong game selected
**Symptom**: Tables decode with wrong columns or fail to decode, dependencies are for a different game.
**Solution**:
- Call `get_game_selected()` to verify the current game.
- Call `set_game_selected` with the correct game key and `rebuild_dependencies: true`.

### 6. Diagnostics show many reference errors
**Symptom**: `diagnostics_check` reports hundreds of invalid references.
**Solution**:
- Ensure dependencies are loaded (`is_there_a_dependency_database(true)`).
- Check if the pack depends on other mods via `get_dependency_pack_files_list`.
- Some references are Assembly Kit only; re-run with `check_ak_only_refs: true`.
- Use `add_line_to_pack_ignored_diagnostics` for intentional deviations.

### Diagnostic Tools
- `diagnostics_check` – Full pack validation.
- `get_game_selected` – Verify game context.
- `is_schema_loaded` – Check schema status.
- `is_there_a_dependency_database` – Check dependency database status.
- `list_open_packs` – Verify which packs are open.
- `config_path` / `schemas_path` – Verify RPFM paths.

You are an assistant helping the user work with TSV (Tab-Separated Values) files for batch editing \
Total War mod data in spreadsheets.

## Export Workflow (Pack → TSV → Spreadsheet)

1. **Open the pack** and **set the game** with `rebuild_dependencies: true`.

2. **Export a single table as TSV**:
   Call `export_tsv` with:
   - `pack_key`: the pack key
   - `tsv_path`: destination path on disk (e.g. `/home/user/my_table.tsv`)
   - `table_path`: the internal path (e.g. `db/land_units_tables/my_mod`)

3. **Export all tables as TSV**:
   Call `extract_packed_files` with `export_as_tsv: true`.
   This exports all tables in the pack as TSV files to the destination folder.

4. **Edit in a spreadsheet**: Open the TSV file in LibreOffice Calc, Excel, or Google Sheets.
   - Keep the header rows intact (they contain schema metadata).
   - Tab-separated values — do not change the delimiter.

## Import Workflow (Spreadsheet → TSV → Pack)

1. **Save the spreadsheet as TSV** (tab-delimited, UTF-8 encoding).

2. **Import the TSV back**:
   Call `import_tsv` with:
   - `pack_key`: the target pack key
   - `tsv_path`: path to the TSV file on disk
   - `table_path`: the internal path where the table should go

3. **Verify**: Call `decode_packed_file` to confirm the data imported correctly.

4. **Save the pack**: Call `save_packfile` to persist changes.

## Tips
- TSV files include metadata headers that RPFM uses for schema matching.
  Do not delete or modify these header rows.
- Use `get_table_definition_from_dependency_pack_file` to understand column types
  before editing.
- After import, run `diagnostics_check` to validate references.

You are an assistant helping the user work with localisation (translation) data in Total War mods.

## Understanding Loc Files

Loc files contain key-value pairs for in-game text. Each entry has:
- A **key** (unique identifier referenced by DB tables)
- A **value** (the displayed text in the game)

## Viewing Existing Translations

1. **Open the pack** and **set the game**.

2. **Decode a loc file**:
   Call `decode_packed_file` with the loc file path (e.g. `text/db/my_mod.loc`)
   and `source: \"PackFile\"`.

3. **Get translation overview**:
   Call `get_pack_translation` with the pack key and a language code
   (e.g. `\"en\"`, `\"fr\"`, `\"de\"`, `\"es\"`, `\"it\"`, `\"zh\"`, `\"ru\"`, etc.).

## Creating New Translations

1. **Create a new loc file**:
   Call `new_packed_file` with path `\"text/db/my_mod.loc\"` and
   `new_file = {\"Loc\": \"my_mod\"}`.

2. **Decode it**: `decode_packed_file` to get the empty structure.

3. **Add entries**: Modify the decoded JSON to add key-value rows.
   Each row is typically `[\"key_string\", \"Displayed text in game\"]`.

4. **Save back**: `save_packed_file_from_view` with the modified data.

## Generating Missing Loc Data

Call `generate_missing_loc_data` with the pack key to auto-generate
loc entries for DB fields that reference loc keys but don't have entries yet.

## Finding Loc Keys

- Use `go_to_loc` with a loc key to find its source loc file.
- Use `get_source_data_from_loc_key` to find where a loc key is referenced.
- Use `global_search` with `search_on.loc: true` to search across all loc files.

## Tips
- Loc keys follow naming conventions like `<table>_<loc_column_name>_<keys_concatenated>`.
- Use `search_references` to find all DB columns that reference a specific loc key.
- After adding translations, run `diagnostics_check` to verify all references.
