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

No annotations are supplied, so the description carries the full behavioral burden, yet it only says "get". It does not state that the call is read-only, whether authentication or an identity is required, what happens when the taskId does not exist, or what the returned detail includes.

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?

A single, front-loaded sentence with zero padding. It is efficiently sized, though its brevity reflects under-specification rather than disciplined compression.

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 two-parameter read with full schema coverage and no output schema, the minimum bar is met by the name-plus-sentence. Still missing is any hint of the return payload (task status, participants, payload) or failure behavior for an unknown taskId.

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 100%, with taskId documented as "Task ID" and chain documented with its enum and default. The description adds no meaning beyond the schema, so the baseline of 3 applies.

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 and resource ("Get A2A task details"), so the basic action is understandable. However, it does not distinguish this tool from siblings such as actora_a2a_my_tasks or actora_a2a_complete_task, leaving the agent to infer that this is the single-task fetch-by-ID operation.

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 when-to-use guidance and no mention of alternatives. The description never says to use this when you already have a taskId, or to use actora_a2a_my_tasks to discover IDs first, so routing must be inferred entirely from the name.

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