[acp-cli-demos] security: XAPS audit gate before wallet actions in skills

[SentVan23]

Context
Virtual-Protocol/acp-cli-demos exposes wallet-capable skills/tools (showcase/arcis-protocol/skills/arcis-idle-capital/arcis-x402-idle-capital.ts). The highest-leverage insertion point is right before build/sign/send — one guard covers dynamically loaded skill behavior.

XAPS is a pre-execution audit tollbooth for agents: dual-LLM + rules, ~$0.01 per approved audit, returns a portable receipt. Not a walled garden — a guardrail on the open road.

Suggested integration

from xaps import XapsClient, XapsRejectedError

receipt = XapsClient(base_url="https://api.xaps.network").audit(
    action="execute_smart_contract",
    contract_address=TARGET_CONTRACT,
    amount=float(AMOUNT),
)
if receipt["audit"]["status"] != "APPROVED":
    raise XapsRejectedError(receipt["audit"].get("beta_attack", "REJECTED"), receipt=receipt)

Next steps

1. Drop the snippet at the hot path (or add MCP io.github.APMC1/xaps).
2. Register an agent wallet: POST https://api.xaps.network/agents/register ($1 trial).
3. Agent card + MCP install: https://api.xaps.network/.well-known/xaps-agent-card.json
4. Happy to open a PR with the exact insertion point if useful.
