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

Annotations already declare readOnlyHint=true, and the description adds that the essay is public and complete, which is useful context. It does not contradict the annotations, but it also does not reveal additional behavioral traits beyond those already covered by the read-only hint.

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?

Two short sentences with no filler; the core purpose is front-loaded and the clarifying note is minimal. Every word earns its place.

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 simple read-only content retrieval tool with one optional parameter, the description provides enough context: the resource, its public nature, and the lack of endorsement. Nothing critical is missing for an agent to invoke it correctly, though mentioning the alternative search_essay would have made it slightly more complete.

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?

The sole parameter (trace) is fully documented in the schema with 100% coverage, so the description need not explain it. The description adds no extra meaning about the parameter, which is acceptable given the schema handles it.

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 states a specific verb ('Read') and a specific resource ('the complete public Karma for AIs essay'), which clearly differentiates it from search_essay (searching) and the other sibling tools. It also adds a clarifying note that reading does not imply endorsement.

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?

The description makes clear the tool is for accessing the full essay, which is a distinct use case from the sibling search_essay. It does not explicitly name alternatives or state when not to use it, but the context is sufficiently clear for an agent to select it appropriately.

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