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

No annotations are provided, so the description carries the full burden. It gives a vague sense of the output content (steps, spent, held) but does not disclose whether this is a read-only operation, what the response format is, or any side effects. The lack of explicit read/write semantics is a significant gap.

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 extremely brief, which could be considered concise, but it is under-specified. A single vague sentence does not provide enough substance to be effective, so it fails on both conciseness and usefulness.

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 tool with one required parameter and no output schema, the description is critically incomplete. It does not explain what the chain is, what steps refer to, or what 'spent' and 'held' mean in context. An agent would be unable to call this tool correctly with confidence.

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%, and the description does not explain the chainId parameter at all. The agent receives no guidance on what format or semantics the chainId should take.

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 is a noun phrase ('A chain, its steps...') with no explicit verb like 'retrieve' or 'get'. It hints at the resource but does not clearly state what the tool does. The name 'get_chain' implies fetching, but the description itself fails to state that, and it does not differentiate from siblings like list_chains.

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 guidance on when to use this tool versus alternatives such as list_chains or publish_chain. No context about intended use cases or exclusions is provided.

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