Zoom Out

Get a map of how a piece of code fits into the bigger picture. Use when you're unfamiliar with an area, about to make changes, or need to understand call chains before modifying behaviour.

When to Invoke

• About to work in an unfamiliar module or subsystem
• Need to understand who calls a function, Manager, or CmdParser handler
• Planning changes that might have side effects elsewhere
• User asks "what touches this?" or "how does this connect?"

Process

1. Identify the Target

Ask or infer what the user wants to understand:

• A specific function, class, Manager, or CmdParser handler
• A subsystem (e.g. "the mail system", "guild logic")
• A data flow (e.g. "how does player login work end to end?")

2. Map Upward — Callers

Walk up from the target:

• Who calls this function/handler? (grep for function name, check CommandRegister.h for command routing)
• What triggers this code path? (client CS command? server-to-server Inter command? timer?)
• Which Managers or Logic layers are involved?

3. Map Downward — Dependencies

Walk down from the target:

• What does this module depend on? (other Managers, utility classes, data loaders)
• What data does it read/write? (player data, global data, caches)
• What protocols does it send/receive? (SC responses, Inter messages)

4. Map Sideways — Peers

Identify related modules at the same level:

• Other handlers in the same CmdParser
• Other methods on the same Manager
• Sibling modules in the same subsystem

5. Present the Map

Output a structured overview:

## Target: <module/function name>

### Call Chain (upward)
Client → CmdParser::<Handler>::onCmd → <Manager>::<method>

### Dependencies (downward)
- <Manager>::getData() — reads player data
- SafeSub() — balance calculation
- SC_<protocol> — sends response to client

### Peers (sideways)
- CmdParser::<OtherHandler> — related command in same parser
- <Manager>::<otherMethod> — sibling operation

### Key Data Flows
- Reads: PlayerData.stXXX, GlobalData.iXXX
- Writes: PlayerData.stXXX (calls setChanged())
- Protocols: CS_XXX → SC_YYY

### Notes
- <any important context: race conditions, ordering constraints, known issues>

Use the project's actual vocabulary — Manager names, struct names, sdp command names — not generic terms.

C++ Game Server Specifics

• Always check CommandRegister.h for command routing (REGISTER_COMMAND entries)
• Look for Manager singletons and their dependencies
• Check .sdp files in Common/ (CS/SC) and Inter/ (server-to-server) for protocol definitions
• Note setChanged() calls — these indicate persistent state modifications
• Identify which layer owns the logic (CmdParser should only parse + delegate, Manager owns business logic)
