Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish this is a safe read (readOnlyHint=true, destructiveHint=false), so the bar is lower. The description adds useful context beyond them: the data is public, and breaking-change entries carry migration notes. It says nothing about result volume, pagination, or whether the full history is always returned.
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 dense sentence where every clause adds information — resource type, accessibility, returned fields, and the special handling of breaking entries. It is front-loaded with the resource identity and has no filler.
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?
With no input parameters and no output schema, the description carries the burden of conveying the return shape, and it does so by listing the fields returned. The only gap is operational detail such as how much history is returned and in what ordering.
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 tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The schema is an empty object and the description correctly focuses on the response shape instead.
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 the specific resource (release history) and enumerates its contents: version, date, type, summary, and migration notes on breaking entries. That is far more concrete than a restatement of the name, and no sibling tool overlaps this resource, so disambiguation is moot rather than missing.
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?
Usage is only implied through the phrase 'the X-Notice header's structured backstory', which hints that this tool should be called to expand on an X-Notice header the agent has encountered. There is no explicit statement of when to call it, when not to, or any alternative source of the same information.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
