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

No annotations are provided, so the description carries full burden. It mentions 'latest data' but doesn't disclose behavioral traits like whether this is a read-only operation, if it requires specific permissions, rate limits, or how 'latest' is defined (e.g., cached vs. real-time). The description is minimal and lacks critical operational context.

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 concise with a single sentence, but it's under-specified rather than efficiently informative. It's front-loaded with the core action but lacks necessary elaboration, making it borderline between brevity and insufficiency.

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?

Given the tool has an output schema (which reduces the need to describe return values) but no annotations and poor parameter coverage, the description is incomplete. It covers the basic purpose but misses usage guidelines, parameter semantics, and behavioral details needed for effective tool selection and invocation.

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 provides no parameter information. It doesn't explain what 'pk' means (e.g., primary key, chart ID) or its format, leaving the single required parameter undocumented. The description fails to compensate for the schema's lack of details.

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 the tool's purpose ('Fetch the latest data for a chart') with a clear verb ('Fetch') and resource ('chart data'), but it's vague about scope and doesn't distinguish from siblings like 'get_chart' or 'list_charts'. It lacks specificity on what 'latest data' entails compared to other chart-related tools.

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 provided on when to use this tool versus alternatives. With siblings like 'get_chart', 'list_charts', and 'update_chart', the description offers no context for selection, such as whether this is for raw data versus metadata or real-time versus cached data.

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