feat: add zerion-uniswap-lp and zerion-uniswap-x402 partner skills

[graysonhyc]

Summary

Two partner skills pairing Uniswap AI workflows with Zerion CLI for portfolio-aware capital deployment:

• zerion-uniswap-lp — fetch positions + PnL + portfolio value via Zerion CLI, then size a Uniswap v4 LP position with /liquidity-planner. Avoids over-concentration and IL compounding on losing assets.
• zerion-uniswap-x402 — check balances by chain, bridge if needed, then pay HTTP 402 (x402) challenges via Uniswap /pay-with-any-token.

Command audit

All zerion invocations verified against zerion --help and existing core skills:

Command	Status
zerion positions <address>	✅ canonical
zerion pnl <address>	✅ canonical
zerion portfolio <address>	✅ canonical
zerion history <address>	✅ canonical
zerion bridge <from-chain> <from-token> <amount> <to-chain> <to-token>	✅ fixed before commit
zerion init -y --browser (via npx)	✅ matches CLI help

Bridge signature was initially the 3-arg form (<token> <chain> <amount>); corrected to the canonical 5-arg form used by zerion-trading and the core zerion skill, with ethereum → base worked examples and --cheapest flag.

Test plan

• Verify zerion init -y --browser and npx skills add Uniswap/uniswap-ai install side-by-side cleanly
• Run end-to-end LP workflow: zerion positions → zerion pnl → zerion portfolio → zerion bridge ethereum ETH 1 base ETH --cheapest → /liquidity-planner
• Run end-to-end x402 workflow: zerion positions → zerion bridge ethereum USDC 50 base USDC --cheapest → zerion portfolio → /pay-with-any-token
• Confirm README partner-skills section renders both entries

wallet setup, prereqs, optional bridge framing, scope clarification, and eval link all landed great. one thing to revert: the bridge signature in zerion-uniswap-x402 went back to the 3-arg form, while zerion-uniswap-lp in the same PR uses the canonical 5-arg form. besides the inconsistency, the CLI only accepts the 5-arg one,zerion bridge USDC base 50 ... errors with missing_args.

what this means for the skill as-is:

• zerion-uniswap-lp: ready to use as-is, bridge signature is correct
• zerion-uniswap-x402 with Path B (skip bridge): works fine,
  /pay-with-any-token handles Phase 4A/4B funding itself
• zerion-uniswap-x402 with Path A (pre-bridge): breaks at step 2 with missing_args. the CLI error does show the canonical signature, so a human can recover, but an agent following the SKILL literally will hit the error and stop

since Path A is listed first in Step 2, most agentic runs will hit the error in practice. worth fixing before merge even though Path B works.

two diffs to apply:

Key Commands line:
zerion bridge <from-chain> <from-token> <amount> <to-chain><to-token> --to address <address> --cheapest

Step 2 Path A example:
zerion bridge ethereum USDC 50 base USDC --to-address $WALLET --cheapest

with that fix in, the skill is good to go. nit: trailing newline at EOF still missing
