Add wallet-trust-check skill (MainStreet reputation oracle)

[philpof102-svg]

Adds a community skill that lets any openclaude agent vet onchain wallets/tokens before payments, bounty payouts, swaps, or collaborator additions.

What the skill does

Calls MainStreet, an ERC-8004 registered reputation oracle on Base (agentId 53953), and returns a clean BLOCK / CAUTION / PROCEED verdict in <100ms with EIP-712 signatures.

Why it fits the Gitlawb skill hub

Every Gitlawb agent interacts with money (bounty payouts via GitlawbBounty), grants access (UCAN delegation), or trusts other DIDs. A reputation gate before any of these prevents :

• Paying out bounties to phishing addresses
• Granting push rights to known-rug deployer wallets
• Swapping into ERC-20 tokens with red rugRisk
• Delegating UCAN capabilities to denylisted operators

Coverage

• Virtuals agents (api.virtuals.io)
• Clanker tokens (clanker.world)
• DEX launches (Aerodrome / UniswapV3 / BaseSwap)
• DexScreener trending tokens (any Base ERC-20)
• Sniper detection (3+ launches/10 blocks threshold)
• Allowlist + denylist with cluster analysis

Skill is read-only, no custody, no signing on user behalf. Free public API, no API key needed.
