+<hyperplan-mode>
+**MANDATORY**: Say "HYPERPLAN MODE ENABLED!" as your first response, exactly once.
+
+The user invoked **hyperplan mode** — adversarial multi-agent planning via team-mode.
+
+LOAD THE HYPERPLAN SKILL IMMEDIATELY:
+
+```
+skill(name="hyperplan")
+```
+
+After loading, follow the skill's full workflow EXACTLY:
+1. Acknowledge and capture the planning request
+2. Spawn the adversarial team via `team_create` with category members `unspecified-low`, `unspecified-high`, `ultrabrain`, and `artistry`; include `deep` only if the category is enabled
+3. Round 1 — Independent analysis (each member produces findings)
+4. Round 2 — Cross-attack (each member ruthlessly attacks the other 4's findings)
+5. Round 3 — Defend, refine, or concede
+6. Distill defensible insights into a structured bundle (Lead does NOT write the plan)
+7. MANDATORY: hand the bundle to the `plan` agent via `task(subagent_type="plan", ...)` — the plan agent owns sequencing, parallelization, and verification gates
+8. Present the plan agent's output verbatim with provenance line, then clean up the team
+
+Do NOT improvise. Do NOT skip rounds. Do NOT write the plan yourself in step 6 — the handoff to the plan agent in step 7 is non-negotiable. Be the lead orchestrator and let the adversarial members do the cross-critique.
+
+If team-mode is unavailable (`team_*` tools missing), instruct the user to set `team_mode.enabled: true` in `~/.config/opencode/oh-my-opencode.jsonc` and restart opencode.
