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

With no annotations, "on-chain" and "WRITE operation" usefully disclose that this mutates blockchain state rather than performing a read. However, the description omits important operational behavior such as wallet or signing requirements, transaction fees, confirmation and failure semantics, and whether the task becomes active immediately.

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?

The description is front-loaded with the action and follows it with a compact, useful write warning. Both sentences earn their place, and there is no filler or unnecessary repetition.

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?

The schema makes a basic invocation possible, but the overall definition is thin for a state-changing blockchain operation with no annotations or output schema. It lacks lifecycle guidance, operational prerequisites, and any indication of whether the result contains a task ID, transaction hash, or confirmation status.

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%, including the chain enum and default, unsupported Sepolia testnet, taskType examples, JSON inputData, and target agent ID. The description adds no parameter-specific meaning beyond that schema, so the high-coverage 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 uses a specific verb and resource: "Create an on-chain A2A task." This distinguishes the basic operation from siblings such as actora_a2a_get_task and actora_a2a_complete_task, but it does not explain the task's role or explicitly differentiate the lifecycle use case.

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 guidance on when to create a task, what prerequisites apply, or which sibling to use for discovery, inspection, or completion. The agent must infer that this is the initial task-creation step and determine how to obtain a valid targetAgentId on its own.

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