Is Collar Guardrail live?

No — it has stopped answering the hub's checks (checked 10h ago). It answered 0% of checks over the last 30 days.

Is Collar Guardrail free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does Collar Guardrail have?

6 tools: Verify audit trail, Evaluate a trade, Check token safety, List supported assets, Simulate a wallet balance, Evaluate a trade (x402 paid, Tier 2).

Is Collar Guardrail safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• verify_audit_trail reads auth-required never probed

  Recompute every past decision's SHA-256 hash and verify the hash-chain links. Proves no decision was edited, deleted, or reordered. If the response contains an 'error' key, verification could not run.

• evaluate_trade reads auth-required never probed

  Pre-trade risk check. Returns allow, warn, or deny, with every reason attached and a tamper-evident audit hash. Checks tier limits, oracle/V4 price source, slippage, market hours, cluster rate limits, and daily loss. If check_token_safety returned severity=danger for the contract, this skill automatically returns deny regardless of other checks. If the response contains an 'error' key, no verdict was produced — treat as a hard stop and do not execute the trade.

• check_token_safety reads auth-required never probed

  Honeypot and contract safety check for any ERC-20 token. Returns severity (safe, warn, danger) and the specific risk factors found, using bytecode analysis and a live sell simulation. CRITICAL: when severity=danger, the next evaluate_trade call for the same contract is automatically denied. Use before trading unknown tokens or tokens absent from the official registry. If the response contains an 'error' key, the check failed — do not assume 'safe'.

• get_supported_assets reads auth-required never probed

  The official Robinhood Chain asset registry with canonical contract addresses. Resolve a symbol correctly before calling evaluate_trade.

• simulate_balance reads auth-required never probed

  Read-only state-override simulation of an ERC-20 balance after a hypothetical trade. No transaction is sent. If the response contains an 'error' key, the simulation failed.

• evaluate_trade_paid auth-required never probed

  Same as evaluate_trade but gated by an x402 payment. Evaluated as Tier 2 ($25,000 ceiling, 10/25 per-minute rate limits). Call WITHOUT payment_proof to receive a PaymentRequiredOutput challenge; settle on-chain; retry with the proof to receive a full verdict with tier=2. No COLR holdings are required — the on-chain payment is the credential. If the response contains an 'error' key, no verdict was produced — treat as a hard stop.
