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

With no annotations present, the description carries the full burden, but it discloses no behavioral traits—no statement that it is read-only, no pagination/ordering, no error or auth behavior. It only conveys the data relationship between chains and a requester.

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?

At four words, the description is brief, but it is under-specified rather than concise and reads as a sentence fragment. The missing verb and awkward word order reduce clarity without adding helpful structure.

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 tool has no output schema and no annotations, yet the description does not describe return values, errors, or pagination. For a one-parameter list operation it gives the core property, but an agent would still be guessing about response shape and edge cases.

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 coverage is 0%, so the description must clarify the requester parameter. It does add the semantic role that requester is the publisher of the chains, but it does not specify the expected format or identifier type for requester.

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?

Description says 'Chains a requester published,' which identifies the resource (chains) and the owner (requester), but lacks an explicit verb such as 'list' or 'return' and is grammatically awkward. The tool name supplies the action, but the description alone is vague and does not contrast with get_chain or publish_chain.

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?

No guidance is given about when to use list_chains versus related tools such as get_chain, publish_chain, or list_cases. The only implied condition is that the caller wants chains associated with a requester's publishing activity.

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