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

The annotations already declare the operation as read-only, idempotent, non-destructive, and closed-world, so the safety profile is clear. The description adds useful behavioral context by listing the returned content (markdown text, article date, superseded flag, URL) and clarifying that it does not generate an article. It does not cover error behavior or auth requirements, but the annotations lower the burden.

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 one tightly constructed sentence that front-loads the main purpose and packs the return fields efficiently. The closing 'Does not generate one' is short and adds a meaningful boundary without waste.

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 one-parameter retrieval tool with no output schema, the description does the important work of explaining what is returned and that no generation occurs. The main remaining gap is the undefined ticker format and the exact behavior when no public article exists, though 'when one is public' partially signals that condition.

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 schema provides no description for the single ticker parameter, and the description only repeats that the article is 'for a ticker.' It does not specify ticker format, casing, exchange qualifiers, or any other semantic detail beyond what the parameter name already implies.

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 retrieval action: fetching the full TradeApes analysis article for a ticker when one is public. It clearly names the resource (AI-written analysis article) and even clarifies that it does not generate one, which helps separate it from generation tools. However, it does not explicitly distinguish itself from siblings like get_score_card or get_valuation.

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 phrase 'when one is public' gives a clear precondition for use, and 'Does not generate one' signals a limitation. But it does not name alternatives or explain what to do when no public article exists, leaving usage guidance implied rather than explicit.

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