v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It usefully discloses the data source ('pushed by the SiteLens extension'), which signals the report may not exist, but it is silent on what happens on an empty store, how 'latest' is determined, and whether the filter searches only history.
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 zero filler, and the core action is front-loaded ahead of the optional filter detail.
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?
There is no output schema, yet the description does not characterize what an AnalysisReport contains or what is returned when nothing matches. For a simple single-parameter read tool this is close, but the undefined return shape leaves a real gap.
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 100% and the single `url` parameter is fully documented, including case-insensitivity. The description's 'Optional url substring filter' merely restates the schema, so baseline 3 is appropriate.
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 gives a specific verb (Return) and resource (the latest AnalysisReport JSON), and 'latest' implicitly separates it from sitelens_list_reports. It never names that sibling explicitly, so the differentiation is inferred rather than stated.
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: fetch the most recent report, optionally narrowed by a URL substring. There is no explicit statement of when to prefer this over sitelens_list_reports or what to do when no report has been pushed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
