keyso_post_tools_combine

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

With no annotations provided, the description carries the full burden of behavioral disclosure, and it fails entirely. It reveals nothing about side effects, output format, response shape, authentication requirements, or limits—only the endpoint and an example URL. The token parameter hints at auth, but the description never confirms it.

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 short, but this is under-specification rather than economy. The only functional sentence is the title phrase; the method, path, and example URL are structural details that belong in the schema, not the description. There is no room spent on the one thing that matters—what the tool does.

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?

This is a POST mutation tool with no output schema, no annotations, and a completely open 'body' parameter. An agent lacks every piece of information needed to invoke it correctly: what to send, what to expect back, and when it is appropriate. The description is radically incomplete for a tool of this complexity.

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 lists three parameters, and although coverage is tagged at 100%, the 'body' parameter is an empty object with no defined properties, so its expected content is completely undocumented. The description adds nothing about what should go into the body. Only 'token' and 'base_url' are self-explanatory from their schema descriptions.

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 opens with 'Комбинатор ключевых фраз' (keyword phrases combinator), which largely restates the verb 'combine' already present in the tool name rather than explaining what combining means functionally (e.g., merging lists vs. building cross-product combinations). The remaining content is structural (POST, path, example URL), not functional. It also fails to differentiate this from similar sibling POST tools like keyso_post_tools_unique and keyso_post_tools_compare.

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?

There is zero guidance on when to use this tool versus the dozens of sibling tools, no stated use case, no prerequisites, and no mention of input expectations. An agent has no way to decide between /tools/combine, /tools/compare, /tools/unique, or /tools/suggest.

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