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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=false, and destructiveHint=false, so the safety profile is covered. The description adds a spec version and notes that cost is not in the public credit manifest, which is useful behavioral context. However, it does not explain what the manifest contains, how it is scoped, or any other operational behavior beyond what annotations provide.

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 and front-loads its main claim about being an auto-generated manifest. The bracketed group and cost lines add metadata without excessive verbosity. It is efficient, though the bracket metadata is only marginally useful for tool selection.

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?

An output schema exists and the input schema is fully documented, so return values and parameters do not need explanation in the description. However, the description remains thin on purpose and usage guidance, making it only minimally complete for an agent deciding whether to call this tool. The low complexity of the tool keeps it from being inadequate, but notable gaps remain.

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 both parameters (fields and precision) are already fully documented in the schema. The description adds no parameter-level meaning beyond what is in the input schema. With complete schema coverage and no additional description detail, a baseline 3 is appropriate.

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 says it is an auto-generated tool manifest for MCP clients, which identifies the general resource but uses no action verb and does not explicitly state that it lists available MCP tools. It also does not distinguish this tool from nearby siblings such as astroway_agent_tools or the MCP-related tools. Purpose is therefore implied rather than clearly stated.

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 only usage context is the phrase 'for MCP clients,' which implies an audience but gives no guidance on when to call this tool versus alternatives. It does not mention prerequisites, exclusions, or sibling tools. This is the same level as a definition that provides only an implied context.

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