get_hashtag_niche

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

With no annotations provided, the description carries the full burden. It states the tool lists niches (a read operation) and describes the return fields (slug, label, description, category). It does not mention side effects, which are absent, and provides sufficient behavioral context for a safe list operation.

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 consists of two efficient sentences: one stating purpose and output, the other giving usage guidance. No wasted words; information is front-loaded.

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?

Despite no output schema, the description explains the return structure (slug, human label, description, category grouping) and the number of items (25). It also provides the usage flow with the sibling tool, making the tool's role clear.

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 100%, so baseline is 3. The only parameter `category` has its enum values documented in the schema description. The tool description does not add extra meaning beyond what the schema already provides.

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 lists 25 curated Instagram hashtag seed niches, specifying the verb 'list', the resource 'Instagram hashtag seed niches', and the scope '25 curated'. It distinguishes itself from the sibling 'search_hashtags' which is for live hashtags.

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 explicitly advises to use 'search_hashtags with the returned slug to get live hashtags for a niche', providing clear when-to-use and when-not-to-use guidance, and naming the alternative tool.

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