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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds a genuinely useful behavioral fact beyond that: the returned command embeds the user's registration secret, which warns the agent the output is sensitive. It does not mention authentication requirements or whether the secret is single-use, keeping it short of a 5.

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?

Two sentences, zero filler, with the resource identified first and the return value second. Nothing is repeated from the title.

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 one-parameter read-only tool with no output schema, the description covers the essentials: what is produced and that it contains a secret. A note on any prerequisite (e.g., that the user must already be registered) would close the only remaining gap.

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 coverage is 100% and the single 'context' parameter is fully specified in the schema, including wording, length and tone constraints, so the baseline of 3 applies. The description says nothing about the parameter, though given how heavily constrained it is in the schema, that omission is tolerable.

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?

Names a specific verb and resource ('Get the install command for the QualityMax local agent') and states the return value ('a pip install command with the user's registration secret'). It does not explicitly differentiate itself from any sibling, though none of the listed siblings plausibly overlap, so the risk of misselection is low.

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?

Usage is only implied: an agent can infer this is for when a user needs to install the local agent. There is no explicit statement of when to call it, no prerequisites (e.g., whether the user must be registered first), and no alternatives referenced.

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