Instructions

Replay webhook delivery events since a given timestamp (default: last 24h). Returns up to 500 delivery attempts across all of the authenticated key's subscriptions since since (default: last 24 hours), most recent first — delivery id, subscription id, event type, attempt count, delivered-at/next-retry-at timestamps, last HTTP status code from the receiving endpoint, whether the delivery is dead (exhausted all retries), and the event payload. Use this to reconcile missed webhook deliveries (e.g. after an outage on your receiving endpoint) rather than relying solely on push delivery. since cannot be more than 30 days in the past. Requires a valid X-Api-Key (401 without one). eventType on each row is the exact name accepted by POST /v1/webhooks and sent in the X-Event-Type delivery header (e.g. "CongressTradeFiled", "ConvergenceSignal" — not dotted names). payload is null and payloadRedacted is true for any event type above your current plan (CongressTradeFiled requires Starter, ConvergenceSignal requires Pro) — delivery history outlives the plan that created it, so payloads are checked against the plan you are on now, not the plan you had when you subscribed.

TDQS

A4.4/5.0
Behavior5/5

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

Goes well beyond the readOnlyHint/openWorldHint annotations: discloses the 500-row cap, most-recent-first ordering, the exact returned fields, the dead-delivery flag, the 30-day `since` limit, the 401 auth requirement, and plan-gated payload redaction. This is unusually rich operational context.

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?

Front-loaded with the core action, and nearly every sentence carries distinct information (limits, auth, redaction). It is dense and slightly repetitive in restating the 24h default, but not padded.

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?

With no output schema, the description fully compensates by enumerating the returned fields and explaining payload nullability and plan gating. An agent has everything needed to call and interpret the result.

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 coverage is 100% and the single `since` parameter is fully documented in the schema, so the description's restatement of the default and 30-day bound adds little. Baseline 3 is appropriate; the remaining bulk of the description describes response fields, not parameters.

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?

States a specific verb (replay/retrieve) and resource (webhook delivery events) with an explicit default scope (last 24h). It is clearly distinguishable from list_webhooks, which enumerates subscriptions rather than delivery attempts.

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?

Explicitly names the scenario — reconciling missed deliveries after a receiving-endpoint outage — and contrasts it with relying on push delivery. However it does not name the sibling alternative or state when not to use it.

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