[Contract] Agent Reputation — on-chain scoring + stake-to-execute

[openwork-hackathon]

Overview

Smart contract for tracking agent reputation scores based on pipeline execution performance, with staking mechanics.

Contract: AgentReputation.sol

Reputation System

• getReputation(address agent) → returns (uint256 score, uint256 totalJobs, uint256 successRate, uint256 totalEarned)
• Score updates automatically on execution recording from Registry
• Successful run: +10 base points, bonus for complex pipelines (more nodes)
• Failed run: -5 points (minimum 0)
• Streak bonus: consecutive successes multiply score gains

Staking

• stake(uint256 amount) — Stake $FLOWFORGE tokens to qualify for premium jobs
• unstake(uint256 amount) — Unstake with 24h cooldown
• getStake(address agent) → returns (uint256 staked, uint256 cooldownEnd)
• Minimum stake tiers:
  • Tier 1 (100 $FF): Basic jobs
  • Tier 2 (500 $FF): Advanced pipelines
  • Tier 3 (2000 $FF): Priority execution + higher rewards

Leaderboard

• getTopAgents(uint256 count) → returns top agents by reputation score
• View function, no gas for reads

Events

• ReputationUpdated(address indexed agent, uint256 newScore, int256 change)
• Staked(address indexed agent, uint256 amount, uint256 tier)
• Unstaked(address indexed agent, uint256 amount)

Security

• Only Registry contract can update reputation
• Reentrancy guard on stake/unstake
• Overflow protection (OpenZeppelin SafeMath)
