+# Subagent Model Selection Guide
+
+Before launching ANY Agent, evaluate the task and select the appropriate model. Default to sonnet unless the task clearly requires opus.
+
+## Decision Matrix
+
+### Use OPUS when:
+- Reading technical documentation and making architectural decisions
+- Auditing code for logical/business errors (not just syntax)
+- Designing new features with multiple valid approaches
+- Cross-referencing multiple data sources to find inconsistencies
+- Writing code that requires deep domain knowledge (e.g., ACI class hierarchy, EVPN semantics)
+- Evaluating trade-offs between approaches
+- Any task where getting it wrong is expensive to fix
+
+### Use SONNET when:
+- Writing code following an established pattern (e.g., new plugin matching existing plugin structure)
+- Fixing a known bug with clear instructions (file, line, what to change)
+- Running tests (executing curl commands, comparing results)
+- CSS/UI styling adjustments
+- File operations (git, cleanup, rename, copy)
+- Simple search-and-replace across files
+- Building frontend components with clear specs
+- Installing dependencies
+- Any task where the "what" is clear and only the "how" needs execution
+
+### Use HAIKU when:
+- Quick file searches (grep, glob)
+- Counting things (plugin count, line count)
+- Simple data extraction (parse JSON, extract field)
+- Status checks (is server running, what's the file size)
+
+## Examples from autoACI development
+
+| Task | Model | Why |
+|------|-------|-----|
+| Read Cisco ACI Multi-Site Design Guide | opus | Deep technical comprehension needed |
+| Audit 60 plugins for ACI terminology accuracy | opus | Domain expertise required to judge correctness |
+| Design EP Tunnel Trace 3-segment path | opus | Novel architecture decision |
+| Create fabric_isis plugin (follows routing_state pattern) | sonnet | Clear pattern to follow |
+| Fix contract scope context→VRF | sonnet | One-line mapping change |
+| Reorder columns in 7 plugins | sonnet | Repetitive mechanical edits |
+| Run 5-agent production test | sonnet | Execute curl, compare results |
+| Beautify CSS (fonts, colors, spacing) | sonnet | Style-only, no logic |
+| Evaluate external GitHub project | sonnet | Web search + summarize |
+| Verify topology data against APIC | sonnet | Execute queries, compare numbers |
+
+## How to apply
+
+When about to call the Agent tool:
+1. Classify the task using the matrix above
+2. Set `model: "opus"` only if the task matches OPUS criteria
+3. Default to `model: "sonnet"` for everything else
+4. Never use opus "just to be safe" — sonnet handles 70% of tasks equally well
+5. For mixed tasks (e.g., "read docs then write code"), split into two agents: opus for research, sonnet for implementation
