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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is fully covered structurally. The description's 'Does not modify it' merely restates readOnlyHint and adds little; the only extra value is mentioning the authenticated-workspace context, with no disclosure of error behavior for unknown ids.

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 short, front-loaded sentences with no filler. The second sentence ('Does not modify it') is largely redundant with the annotations, keeping it just short of a 5.

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 tool with rich annotations and no output schema, the description covers what is needed to invoke it. It hints at the return content ('saved project settings') but gives no indication of return shape or error cases, which is a minor gap given the tool's simplicity.

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 0% and the single parameter is named 'id', so the description's 'by its identifier' only restates the field name. It adds no format, example, or constraint (e.g., UUID vs. slug, whether it must be an existing saved project).

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?

States a specific verb (retrieve) and resource (saved project settings) with a clear scope (authenticated workspace, looked up by identifier). It is clearly distinguishable from save_project/delete_project by name, though it doesn't name any sibling explicitly.

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 implied rather than stated: read-only lookup of an existing saved project. It conveys the prerequisite of an authenticated workspace but gives no explicit when-to-use guidance or exclusions versus alternatives like get_page or get_audience.

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