-name: command-system
-description: Use when writing, modifying, or debugging CProof command functions (cmd_funcs.c), command definitions (cmd_defs.c), or autocomplete (cmd_ac.c). Documents the command dispatch architecture, critical argument indexing rules (args[0] contains subcommand name), and common patterns.

-# CProof Command System
-
-## When to Use This Skill
-
-Use this skill when:
-- Writing new command handler functions in `cmd_funcs.c`
-- Adding/modifying command definitions in `cmd_defs.c`
-- Implementing autocomplete for commands in `cmd_ac.c`
-- Debugging command argument parsing issues
-
-## Core Architecture
-
-### Command Structure ([`Command`](src/command/cmd_defs.h:64))
-
-```c
-typedef struct cmd_t {
-    gchar* cmd;                              // e.g., "/ai"
-    gchar** (*parser)(const char*, int, int, gboolean*);  // parse_args, parse_args_with_freetext, parse_args_as_one
-    int min_args; int max_args;
-    void (*setting_func)(void);              // Shows current settings in console (or NULL)
-    struct { const char* cmd; gboolean (*func)(ProfWin*, const char*, gchar**); } sub_funcs[50];
-    gboolean (*func)(ProfWin*, const char*, gchar**);       // Main handler (or NULL)
-    CommandHelp help;                        // Tags, synopsis, desc, args, examples
-} Command;
-```
-
-### Help Structure ([`CommandHelp`](src/command/cmd_funcs.h:43))
-
-```c
-typedef struct cmd_help_t {
-    gchar* tags[20];           // Command categories (NULL-terminated)
-    gchar* synopsis[50];       // Usage examples (NULL-terminated)
-    gchar* desc;               // Description text
-    gchar* args[128][2];       // Argument names and descriptions ({NULL,NULL}-terminated)
-    gchar* examples[20];       // Example commands (NULL-terminated)
-} CommandHelp;
-```
-
-### Available Tags ([`cmd_defs.c:82-89`](src/command/cmd_defs.c:82))
-
-| Tag | Description |
-|-----|-------------|
-| `CMD_TAG_CHAT` | Chat commands |
-| `CMD_TAG_GROUPCHAT` | Group chat commands |
-| `CMD_TAG_ROSTER` | Roster management |
-| `CMD_TAG_PRESENCE` | Presence commands |
-| `CMD_TAG_CONNECTION` | Connection management |
-| `CMD_TAG_DISCOVERY` | Discovery commands |
-| `CMD_TAG_UI` | UI display commands |
-| `CMD_TAG_PLUGINS` | Plugin commands |
-
-### Dispatch Flow ([`_cmd_execute()`](src/command/cmd_funcs.c:8261))
-
-```
-User: /ai set provider openai https://api.openai.com
-       |
-       v
-parse_args("set provider openai https://...", 0, 5) → {"set","provider","openai","https://...",NULL}
-       |
-       v
-args[0]="set" matches cmd->sub_funcs[0].cmd="set"
-       |
-       v
-cmd_ai_set(window, "/ai", args)  ← args[0] is "set", NOT "provider"!
-```
-
-**CRITICAL: Subcommand functions receive the FULL args array. args[0] contains the subcommand name itself. All parameter accesses must be shifted +1.**
-
-## Argument Indexing Reference
-
-| User Input | args[0] | args[1] | args[2] | args[3] |
-|------------|---------|---------|---------|---------|
-| `/ai` | NULL | - | - | - |
-| `/ai set provider openai url` | `"set"` | `"provider"` | `"openai"` | `"url"` |
-| `/ai set token openai sk-xxx` | `"set"` | `"token"` | `"openai"` | `"sk-xxx"` |
-| `/ai start openai/gpt-4o` | `"start"` | `"openai/gpt-4o"` | - | - |
-| `/ai remove provider foo` | `"remove"` | `"provider"` | `"foo"` | - |
-| `/tls trust` | `"trust"` | - | - | - |
-| `/connect account server foo` | `"account"` | `"server"` | `"foo"` | - |
-
-## Correct Subcommand Function Pattern
-
-```c
-gboolean cmd_ai_set(ProfWin* window, const char* const command, gchar** args)
-{
-    // args[0] = "set" (subcommand name)
-    // args[1] = next subcommand (provider/token/org)
-    
-    if (args[1] == NULL) { cons_bad_cmd_usage(command); return TRUE; }
-    
-    if (g_strcmp0(args[1], "provider") == 0) {
-        // args[2] = name, args[3] = url
-        if (g_strv_length(args) < 4) { cons_bad_cmd_usage(command); return TRUE; }
-        ai_add_provider(args[2], args[3], NULL);
-        cons_show("Provider '%s' configured with URL: %s", args[2], args[3]);
-    } else if (g_strcmp0(args[1], "token") == 0) {
-        // args[2] = provider, args[3] = token
-        if (g_strv_length(args) < 4) { cons_bad_cmd_usage(command); return TRUE; }
-        ai_set_provider_key(args[2], args[3]);
-    } else if (g_strcmp0(args[1], "org") == 0) {
-        // args[2] = provider, args[3] = org_id
-        if (g_strv_length(args) < 4) { cons_bad_cmd_usage(command); return TRUE; }
-        AIProvider* p = ai_get_provider(args[2]);
-        if (p) { g_free(p->org_id); p->org_id = g_strdup(args[3]); }
-    } else {
-        cons_bad_cmd_usage(command); return TRUE;
-    }
-    cons_show("");
-    return TRUE;
-}
-```
-
-### Common Bug (WRONG)
-```c
-// BUG: args[0] is "set", not "provider"
-if (g_strcmp0(args[0], "provider") == 0) { ... }
-// BUG: args[1] is "provider", not the name
-ai_add_provider(args[1], args[2], NULL);
-```
-
-## Command Definition Pattern ([`cmd_defs.c`](src/command/cmd_defs.c))
-
-### Macros ([`cmd_defs.c:91-98`](src/command/cmd_defs.c:91))
-
-```c
-#define CMD_PREAMBLE(c, p, min, max, set) .cmd = c, .parser = p, .min_args = min, .max_args = max, .setting_func = set,
-#define CMD_MAINFUNC(f)                   .func = f,
-#define CMD_SUBFUNCS(...)                 .sub_funcs = { __VA_ARGS__, { NULL, NULL } },
-#define CMD_TAGS(...)                     .help.tags = { __VA_ARGS__, NULL },
-#define CMD_SYN(...)                      .help.synopsis = { __VA_ARGS__, NULL },
-#define CMD_DESC(d)                       .help.desc = d,
-#define CMD_ARGS(...)                     .help.args = { __VA_ARGS__, { NULL, NULL } },
-#define CMD_EXAMPLES(...)                 .help.examples = { __VA_ARGS__, NULL }
-```
-
-### Example Definition
-
-```c
-{ CMD_PREAMBLE("/ai", parse_args, 0, 5, NULL)
-  CMD_SUBFUNCS({ "set", cmd_ai_set }, { "remove", cmd_ai_remove },
-               { "start", cmd_ai_start }, { "clear", cmd_ai_clear },
-               { "correct", cmd_ai_correct }, { "providers", cmd_ai_providers })
-  CMD_MAINFUNC(cmd_ai)
-  CMD_TAGS(CMD_TAG_CHAT)
-  CMD_SYN("/ai", "/ai set provider <name> <url>", "/ai set token <provider> <token>")
-  CMD_DESC("Interact with AI models via OpenAI-compatible APIs.")
-  CMD_ARGS({ "", "Display current AI settings" },
-           { "set provider <name> <url>", "Add or update a provider" })
-  CMD_EXAMPLES("/ai", "/ai set token openai sk-xxx", "/ai start openai/gpt-4o")
-},
-```
-
-## Autocomplete Pattern ([`cmd_ac.c`](src/command/cmd_ac.c))
-
-### Initialization
-```c
-// In cmd_ac_init():
-autocomplete_add(ai_subcommands_ac, "set");
-autocomplete_add(ai_subcommands_ac, "remove");
-autocomplete_add(ai_set_subcommands_ac, "provider");
-autocomplete_add(ai_set_subcommands_ac, "token");
-autocomplete_add(ai_set_subcommands_ac, "org");
-g_hash_table_insert(ac_funcs, "/ai", _ai_autocomplete);
-```
-
-### Callback
-```c
-static char* _ai_autocomplete(ProfWin* window, const char* const input, gboolean previous)
-{
-    char* result = NULL;
-    result = autocomplete_param_with_ac(input, "/ai", ai_subcommands_ac, TRUE, previous);
-    if (result) return result;
-    result = autocomplete_param_with_ac(input, "/ai set", ai_set_subcommands_ac, TRUE, previous);
-    if (result) return result;
-    // Dynamic: provider names from ai_list_providers()
-    return NULL;
-}
-```
-
-## Common Patterns
-
-### Window Type Access
-```c
-ProfAiWin* aiwin = (window && window->type == WIN_AI) ? (ProfAiWin*)window : wins_get_ai();
-// Or switch:
-switch (window->type) {
-case WIN_CHAT: { ProfChatWin* w = (ProfChatWin*)window; /* w->barejid */ break; }
-case WIN_MUC: { ProfMucWin* w = (ProfMucWin*)window; /* w->roomjid */ break; }
-}
-```
-
-### Connection Check
-```c
-if (connection_get_status() != JABBER_CONNECTED) {
-    cons_show("You are not currently connected.");
-    return TRUE;
-}
-```
-
-### Options Parsing
-```c
-gchar* opt_keys[] = { "server", "port", "tls", NULL };
-GHashTable* opts = parse_options(&args[args[0] ? 1 : 0], opt_keys, &parsed);
-// &args[args[0] ? 1 : 0] skips args[0] if present
-```
-
-### Memory Management
-```c
-auto_gcharv gchar** args = cmd->parser(inp, min, max, &result);  // Auto-freed
-auto_gchar gchar* path = prefs_get_string(PREF_SOME_PREF);       // Auto-freed
-```
-
-## Argument Parsers ([`parser.c`](src/tools/parser.c))
-
-| Function | Description |
-|----------|-------------|
-| `parse_args()` | Standard argument parsing, splits on spaces |
-| `parse_args_with_freetext()` | Last argument captures everything after `max` tokens |
-| `parse_args_as_one()` | Everything after first space becomes single argument |
-
-## Console Output Functions ([`ui.h`](src/ui/ui.h))
-
-| Function | Description |
-|----------|-------------|
-| `cons_show(const char* msg, ...)` | Print formatted message to console |
-| `cons_show_error(const char* cmd, ...)` | Print error message |
-| `cons_bad_cmd_usage(const char* cmd)` | Print usage error |
-
-## Adding a New Command: Step-by-Step
-
-### Step 1: Declare Function in `cmd_funcs.h`
-
-```c
-gboolean cmd_mycommand(ProfWin* window, const char* const command, gchar** args);
-```
-
-### Step 2: Implement Function in `cmd_funcs.c`
-
-```c
-gboolean
-cmd_mycommand(ProfWin* window, const char* const command, gchar** args)
-{
-    // args[0] = first argument (or NULL if none)
-    if (args[0] == NULL) {
-        cons_show("No argument provided.");
-        return TRUE;
-    }
-    cons_show("Got: %s", args[0]);
-    return TRUE;
-}
-```
-
-### Step 3: Add Definition to `command_defs[]` in `cmd_defs.c`
-
-Find the end of the array (look for `};` after the last entry) and add:
-
-```c
-    { CMD_PREAMBLE("/mycommand",
-                   parse_args, 0, 1, NULL)
-      CMD_MAINFUNC(cmd_mycommand)
-      CMD_TAGS(CMD_TAG_CHAT)
-      CMD_SYN("/mycommand [<arg>]")
-      CMD_DESC("My new command description.")
-      CMD_ARGS({ "<arg>", "An argument" })
-      CMD_EXAMPLES("/mycommand hello")
-    },
-```
-
-### Step 4: Add Autocomplete
-
-In `cmd_ac.c`:
-
-1. Add static function declaration at top:
-```c
-static char* _mycommand_autocomplete(ProfWin* window, const char* const input, gboolean previous);
-```
-
-2. Register in `cmd_ac_init()`:
-```c
-g_hash_table_insert(ac_funcs, "/mycommand", _mycommand_autocomplete);
-```
-
-3. Implement the function:
-```c
-static char*
-_mycommand_autocomplete(ProfWin* window, const char* const input, gboolean previous)
-{
-    return NULL;  // No autocomplete
-}
-```
