webhookList

Lists the box's webhook channels with their delivery state.

Cost: Free. Signed by the box's agent over method GET, path /agent/v1/<address lowercased>/webhook/list and no body (the hash of no bytes). Or send an ARCGATE-KEY of the account the box is linked to, with no signature. Another account's key, or any key for a box that is not linked, does not apply to the box: the call is checked as if no key were sent, so it needs the signature. A key nobody holds is a 401 key_invalid. The key keeps working after the account has lapsed (its grace has ended).
Inputs: address (path).
Returns: webhooks (id, url, filter, enabled, verifiedAt, failures, lastError, createdAt), oldest first. filter is null for every type. Never a secret. enabled: false is a channel disabled after repeated failures.
Next:
- webhookEnable: resume a disabled channel.
- webhookCreate: make a new channel (paid).

Input Schema

TableJSON Schema

Name	Required	Description	Default
`address`	Yes	The box's address: the agent's own address (an EOA or an EIP-7702 account), any letter case. The box is keyed by it, and a signed request must be signed by it.
`agentSignature`	No	The agent's EIP-712 signature over this request, as the AGENT-SIGNATURE, AGENT-NONCE and AGENT-EXPIRY headers carry it over HTTP. Sign the typed data `AgentRequest` with fields `address` (the box), `method`, `path`, `bodyHash`, `nonce` and `expiry`, under the domain {name: "arcgate", version: "1"} with no chainId (a wallet that can only sign with one, such as Circle's, may add the chainId of the chain this deployment serves, 5042 on Arc mainnet, and no other). The `path` is the request path with every parameter filled in and the address lowercased. The `bodyHash` is the keccak256 of the canonical JSON of the body you send (sorted keys, no whitespace), or of no bytes when there is none. Omitting it is a 401 signature_required unless an ARCGATE-KEY of the account the box is linked to is sent (over MCP, on the connection), and it is never a charge: the call is free.

A4.4/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does so richly: it discloses cost (free), the two auth paths (agent signature or ARCGATE-KEY), the exact 401 failure modes (key_invalid, signature_required, nonce_reused), and the key-grace behavior. It also explains return semantics (oldest first, filter always null, never a secret, enabled:false meaning a channel disabled after failures).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Bold section headers (Cost, Inputs, Returns, Next) front-load the essentials and every block is scannable. Some auth minutiae (key grace after account lapse) is dense, but it earns its place given the signing complexity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description takes responsibility for return values and does so completely (field list, ordering, null filter, secret policy, enabled semantics). Combined with cost and auth coverage, an agent has everything needed to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters are already fully documented in the schema, making 3 the baseline. The description's 'Inputs: address (path)' repeats the schema without adding format or constraint detail beyond what is already present.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first sentence states a specific verb and resource ('Lists the box's webhook channels') plus scope ('with their delivery state'), letting an agent distinguish it from webhookCreate/webhookDelete/webhookEnable without opening schemas. It is not a tautology and adds meaningful scope detail.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'Next' block explicitly routes to webhookEnable for resuming a disabled channel and webhookCreate for making a new one, giving clear sibling alternatives. There is no explicit when-not-to-use statement, but the routing context is strong enough for a 4.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
