Trigger
Use when the task involves:
- strategic interaction with explicit players and payoffs
- best responses, incentives, or equilibrium selection
- normal-form, extensive-form, or repeated-game reasoning
- mechanism design or credibility questions at a lightweight project level
Workflow
- Restate the primitives: players, actions, payoffs, timing, and information.
- Name the equilibrium concept before solving.
- Check best-response logic, beliefs, and incentive constraints explicitly.
- Distinguish the formal result from intuition, welfare discussion, or extensions.
Guardrails
- Do not switch equilibrium concepts mid-analysis.
- Keep off-path beliefs explicit in sequential games.
- State how multiplicity, tie-breaking, or equilibrium selection is handled.
- Separate existence, uniqueness, and comparative-statics claims.
