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

With no annotations, the description carries the full behavioral burden, and it discloses only that this retries an event with its original ID. It does not state whether the operation is idempotent, whether it can duplicate deliveries, what permissions are required, or what happens on a successful versus failed replay.

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

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

It is a single front-loaded sentence with no filler or repetition. It is efficient, though its brevity reflects under-specification rather than tightly packed information.

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

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

For a mutation tool with two required parameters, no annotations, no output schema, and zero schema coverage, the description is too thin. It omits workspaceId semantics, expected outcomes, error behavior, and any routing to sibling tools like events_list.

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

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

Schema description coverage is 0%, so the description must compensate, but it only clarifies the 'id' parameter as the original event ID. It never mentions workspaceId, leaving one of the two required UUID parameters with no semantic explanation beyond its name.

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

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

The description names a specific verb+resource ('Retry delivery of this event') and is clearly distinct from the sibling events_list, which lists rather than replays. The only weakness is that 'this event' is deictic and does not explicitly frame the operation as a mutation of an existing event by ID.

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

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

There is no explicit when-to-use statement, no when-not condition, and no named alternative such as events_list for inspecting events before replaying. The retry framing implies the trigger is a previously failed delivery, but the agent is left to infer that entirely.

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