Fen Ecosystem

The Mechanic/Fen ecosystem is a unified platform for WoW addon development.

The Reload Loop (MANDATORY)

After ANY addon code change, you MUST verify the changes in-game:

Ask the user to
```
/reload
```
in WoW (or trigger via keybinding CTRL+SHIFT+R)
Wait for the user to confirm the reload is complete
Then use the
```
addon.output
```
MCP tool (agent_mode=true) to get errors, tests, and console logs

CRITICAL: Do NOT call
addon.output
immediately after changes. The timing between reload and SavedVariables sync is unpredictable. Always wait for user confirmation.

Ecosystem Components

Component	Purpose	Key Tools
Mechanic	Development hub (CLI, MCP, Dashboard)	`env.status` , `addon.output` , `addon.lint` , `addon.test`
FenCore	Pure logic library (no UI dependencies)	`fencore.catalog` , `fencore.search` , `fencore.info`
FenUI	UI widget library (frames, layouts)	`Layout` , `Panel` , `Tabs` , `Grid` , `Buttons`
MechanicLib	Bridge library (addon ↔ Mechanic)	`RegisterAddon` , `Print` , `RegisterTest`

Essential MCP Tools

Task	MCP Tool
Get Addon Output	`addon.output(agent_mode=true)`
Lint Code	`addon.lint(addon="MyAddon")`
Run Tests	`addon.test(addon="MyAddon")`
Search APIs	`api.search(query="Spell")`
Search FenCore	`fencore.search(query="clamp")`
Env Status	`env.status()`

AFD Core Principles

Mechanic follows Agent-First Development (AFD) — github.com/Falkicon/afd

Tool-First: All functionality exists as an MCP tool before any UI
Structured Results: Tools return predictable JSON with
```
success
```
,
```
data
```
,
```
error
```
Agent Mode: Use
```
agent_mode=true
```
for AI-optimized output
