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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds only that status defaults to published, repeating the schema default, and says nothing about result cardinality, pagination, or whether an omitted site spans all sites. Modest added value on top of a rich annotation set.

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 fragments with no padding, front-loaded with the resource and followed by the filter enumeration. It is efficient, though the fragment style leaves the operation itself unstated, which is under-specification rather than verbosity.

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 three-parameter, no-required-argument list tool with no output schema, the description does not say what comes back or how results are bounded, leaving the agent guessing at return shape. The one thing it clarifies, the status default, is already structured. Adequate but with a clear gap around return behavior.

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 67%, with lang and site documented directly and status carrying an enum plus default. The description's status list restates the enum rather than adding meaning, and it never explains the semantics of omitting site. Baseline 3 is appropriate since the schema does most of the work.

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 is a noun phrase naming the resource ('Markdown documents of a site in Content Studio') rather than stating a verb, so the listing action is only recoverable from the tool name and title. It does add the Content Studio domain and the status dimension, which orients the agent somewhat. Still closer to a tautological restatement than a distinct statement of purpose.

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 guidance is the status default ('published'), which the schema already carries. There is no hint about when to prefer this over siblings like list_urls, search, get_document, or get_site_overview, all of which overlap in scope. No exclusions or prerequisites are offered.

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