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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered and the bar is lower. The description adds only that content comes from the docs and includes a link, but says nothing about return shape, whether all four client guides are returned at once, or whether the link is always present.

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?

It is a single sentence of reasonable length, but the front-loading is weak — it opens with a long noun clause ('How an ElfHosted customer connects their agent...') that describes a topic rather than the tool, and the operative clause lands at the very end.

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?

With no parameters and no output schema, the description needs to explain what comes back; it partially does ('Read from the docs, with the link'). However, it leaves open whether the answer is a doc excerpt, a static guide, or a URL, which matters for an agent deciding between this and search_docs.

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 tool takes zero parameters, which is the baseline 4 case. The description is consistent with that: it implies a fixed, no-argument documentation lookup rather than a parameterized search, so nothing is missing.

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 identifies the subject (connecting an agent to a private MCP server, with per-client steps for claude.ai, ChatGPT, Claude Code, Cursor) but never names the action the tool performs. Only the trailing phrase 'Read from the docs, with the link' hints that it retrieves documentation, and even that is phrased as an instruction rather than a statement of what the tool does.

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 no explicit when-to-use guidance and no differentiation from the doc-oriented siblings get_doc, search_docs, or find_my_setup. An agent cannot tell from the text whether this should be preferred over search_docs for connection questions, or whether the per-client steps are returned together or selected somehow.

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