├─► 3. Inject ROM Context
│ Current state from application:
│ • Loaded ROM path
│ • Open editors (Overworld, Dungeon)
│ • Recently modified assets
│
├─► 4. Set Output Format Rules
│ • MUST return JSON array of strings
│ • Each string is executable z3ed command
│ • No explanations or markdown
│
└─► 5. Combine into Final Prompt
System Prompt (~2K tokens) + User Prompt

## Data Flow Example: "Make soldier armor red"
```
1. User Input
$ z3ed agent run --prompt "Make soldier armor red" --rom zelda3.sfc --sandbox
2. Agent Handler
• Create proposal (ID: agent_20251003_143022)
• Create sandbox (/tmp/yaze_sandbox_abc123/zelda3.sfc)
• Select AI service (Ollama detected)
3. Ollama Service
• Check health: ✓ Running on localhost:11434
• Check model: ✓ qwen2.5-coder:7b available
• Build prompt:
System: "<full resource catalogue> + <few-shot examples>"
User: "Make soldier armor red"
• Call API: POST /api/generate
• Response:
```json
{
"response": "[\"palette export --group sprites --id soldier --to /tmp/soldier.pal\", \"palette set-color --file /tmp/soldier.pal --index 5 --color FF0000\", \"palette import --group sprites --id soldier --from /tmp/soldier.pal\"]"
}
```
• Parse: Extract 3 commands
4. Command Execution
┌────────────────────────────────────────────────────────┐
│ Command 1: palette export --group sprites --id soldier │
│ Handler: PaletteHandler::HandleExport() │
│ Status: ✓ Success (wrote /tmp/soldier.pal) │
│ Duration: 45ms │
├────────────────────────────────────────────────────────┤
│ Command 2: palette set-color --file /tmp/soldier.pal │
│ Handler: PaletteHandler::HandleSetColor() │
│ Status: ✓ Success (modified index 5 → #FF0000) │
│ Duration: 12ms │
├────────────────────────────────────────────────────────┤
│ Command 3: palette import --group sprites --id soldier │
│ Handler: PaletteHandler::HandleImport() │
│ Status: ✓ Success (applied to sandbox ROM) │
│ Duration: 78ms │
└────────────────────────────────────────────────────────┘
5. Proposal Registry
• Log all commands
• Calculate ROM diff (before/after)
• Set status: PENDING_REVIEW
6. Output to User
✅ Agent run completed successfully.
Proposal ID: agent_20251003_143022
Sandbox: /tmp/yaze_sandbox_abc123/zelda3.sfc
Use 'z3ed agent diff' to review changes
7. User Review
$ z3ed agent diff
Proposal: agent_20251003_143022
Prompt: "Make soldier armor red"
Status: pending
Created: 2025-10-03 14:30:22
Executed Commands:
1. palette export --group sprites --id soldier --to /tmp/soldier.pal
2. palette set-color --file /tmp/soldier.pal --index 5 --color FF0000
3. palette import --group sprites --id soldier --from /tmp/soldier.pal
ROM Diff:
Modified palettes: [sprites/soldier]
Changed bytes: 6
Offset 0x12345: [old] 00 7C 00 → [new] 00 00 FF
8. GUI Review
Open YAZE → Debug → Agent Proposals
• Visual diff shows red soldier sprite
• Click "Accept" → Merge sandbox to main ROM
• Or "Reject" → Discard sandbox
9. Finalization
$ z3ed agent commit
✅ Proposal accepted and merged to zelda3.sfc
