Overview

This skill implements the Tit for Tat (TFT) strategy for repeated interactions like negotiations, workplace dynamics, and ongoing relationships. It frames decisions around a clear, reciprocal rule set: start with cooperation, mirror the other party's last move, punish a defection once, then forgive if they return to cooperation. The approach emphasizes predictable signaling, limited retaliation, and recovery pathways to maximize long-term mutual benefit.

How this skill works

The skill analyzes whether interactions are repeated and observable and recommends an initial cooperative move when appropriate. It then prescribes matching the counterpart's previous action: cooperate after cooperation, defect once after defection, and return to cooperation if the counterpart repairs the relationship. It also suggests variants (Generous TFT, Tit for Two Tats) and communication templates to avoid misunderstandings and break accidental defection cycles.

When to use it

• Ongoing workplace relationships with recurring tasks
• Long-term business partnerships and negotiations
• Designing reputation or trust systems in platforms
• Managing team dynamics and recurrent conflicts
• When interactions are observable and future encounters are likely

Best practices

• Start new relationships with a cooperative move to signal good faith
• Be immediately retaliatory but limit punishment to a single matched move
• Forgive promptly when the other party returns to cooperation to restore mutual benefit
• Communicate clearly after a punishment to avoid noise-driven spirals
• Use Generous TFT or Tit for Two Tats in noisy environments to reduce accidental escalation

Example use cases

• A coworker misses a deadline: address the issue, match the response once, then forgive when reliability returns
• A negotiation where the partner lowballs: respond firmly without escalating, resume concessions once they signal reasonableness
• Platform design for peer ratings: reward cooperative behavior and mirror sanctions for bad actors while allowing recovery
• Friend repeatedly cancels plans: set clear boundary after repeated defections, then reinvest when they show consistent reliability
