## Common Patterns

### Check Group Type and Size

```lua
local function GetGroupInfo()
    if IsInRaid() then
        return "raid", GetNumGroupMembers()
    elseif IsInGroup() then
        return "party", GetNumGroupMembers()
    else
        return "solo", 1
    end
end
```

### Iterate Group Members

```lua
local function ForEachGroupMember(callback)
    local prefix = IsInRaid() and "raid" or "party"
    local numMembers = GetNumGroupMembers()
    
    if IsInRaid() then
        for i = 1, numMembers do
            callback(prefix .. i)
        end
    else
        callback("player")
        for i = 1, numMembers - 1 do
            callback(prefix .. i)
        end
    end
end

ForEachGroupMember(function(unit)
    print(UnitName(unit), UnitGroupRolesAssigned(unit))
end)
```

### Search Premade Groups

```lua
-- Search for M+ groups
local CATEGORY_DUNGEON = 2
C_LFGList.Search(CATEGORY_DUNGEON, "")

local frame = CreateFrame("Frame")
frame:RegisterEvent("LFG_LIST_SEARCH_RESULTS_RECEIVED")
frame:SetScript("OnEvent", function()
    local totalResults, results = C_LFGList.GetSearchResults()
    for _, resultID in ipairs(results) do
        local info = C_LFGList.GetSearchResultInfo(resultID)
        if info then
            print(info.name, info.comment, info.numMembers)
        end
    end
end)
```

## Gotchas & Restrictions

1. **InviteUnit requires hardware event** — Must be called from a user click/key handler.
2. **Party vs raid iteration** — Use different unit tokens: `"party1"-"party4"` vs `"raid1"-"raid40"`. Player is NOT in party tokens.
3. **Category matters** — `IsInGroup()` defaults to `LE_PARTY_CATEGORY_HOME`. Use `LE_PARTY_CATEGORY_INSTANCE` for LFG groups.
4. **GROUP_ROSTER_UPDATE fires often** — Debounce processing. Fires for role changes, joins, leaves, subgroup changes.
5. **LFG search is async** — `C_LFGList.Search()` is async. Wait for `LFG_LIST_SEARCH_RESULTS_RECEIVED`.
6. **SendAddonMessage in instances** — Blocked in 12.0.0. Group addons cannot communicate via addon messages in instances.
7. **Cross-faction groups** — Check `C_PartyInfo.IsCrossFactionParty()` to handle cross-faction UI properly.
8. **Raid markers require assist** — `SetRaidTarget()` requires leader or assistant in raids.
