+## Council skill created
+- Built `skills/council/` — multi-perspective advisory council using subagents.
+- Design decisions (agreed with Will):
+  - Implemented as a **skill** (not standalone agents).
+  - 3 advisors (Pragmatist, Visionary, Skeptic) + 1 Referee = 4 subagents total.
+  - Referee is a separate subagent (not the session model) — can use a stronger model tier.
+  - Default flow: **Parallel + Synthesis**. Sequential and Debate flows also available.
+  - Final output includes individual advisor perspectives (collapsed/summarized) + referee verdict.
+  - Model tier chosen per-invocation based on topic complexity.
+- Files: `SKILL.md`, `references/prompts.md`, `scripts/council.sh` (reference doc).
+- Validated with skill-creator quick_validate.
+- Two TODOs added to `memory/tasks.json`:
+  - Revisit advisor personality depth (richer backstories).
+  - Revisit skill name ("council" is placeholder).
