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

With no annotations, the description carries the full burden. It indicates a read operation ('Get recent posts') but does not disclose any behavioral traits such as rate limits, data freshness, or whether authentication is required. The minimal description is acceptable for a simple search tool.

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 extremely concise: two sentences that efficiently convey the purpose and a key usage tip. No unnecessary words or repetition.

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?

The description is adequate for the tool's simplicity but lacks details about the output (though an output schema exists) and the behavior of the 'amount' parameter. It could also mention differences from similar tools like 'instagram_get_hashtag_top_posts'.

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 description only addresses the 'hashtag' parameter with a formatting instruction, but does not explain the 'amount' parameter (default 12, integer). Given 0% schema description coverage, more explanation is needed for both parameters.

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 clearly states the tool retrieves recent posts for a hashtag, with a specific verb and resource. It distinguishes from sibling tools like 'instagram_get_hashtag_top_posts' by specifying 'recent' posts. The instruction to omit the '#' symbol adds clarity.

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 provides clear context for when to use the tool (to get recent posts for a hashtag) and includes a formatting instruction. However, it does not explicitly state when not to use it or mention alternatives among siblings.

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