+# Model Profile Resolution
+
+Resolve model profile once at the start of orchestration, then use it for all Task spawns.
+
+## Resolution Pattern
+
+```bash
+MODEL_PROFILE=$(cat .planning/config.json 2>/dev/null | grep -o '"model_profile"[[:space:]]*:[[:space:]]*"[^"]*"' | grep -o '"[^"]*"$' | tr -d '"' || echo "balanced")
+```
+
+Default: `balanced` if not set or config missing.
+
+## Lookup Table
+
+@.agent/get-shit-done/references/model-profiles.md
+
+Look up the agent in the table for the resolved profile. Pass the model parameter to Task calls:
+
+```
+Task(
+  prompt="...",
+  subagent_type="gsd-planner",
+  model="{resolved_model}"  # "inherit", "sonnet", or "haiku"
+)
+```
+
+**Note:** Opus-tier agents resolve to `"inherit"` (not `"opus"`). This causes the agent to use the parent session's model, avoiding conflicts with organization policies that may block specific opus versions.
+
+If `model_profile` is `"inherit"`, all agents resolve to `"inherit"` (useful for OpenCode `/model`).
+
+## Usage
+
+1. Resolve once at orchestration start
+2. Store the profile value
+3. Look up each agent's model from the table when spawning
+4. Pass model parameter to each Task call (values: `"inherit"`, `"sonnet"`, `"haiku"`)
