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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world). The description adds genuinely new behavior: documents are caller-supplied text and source retrieval is deferred until after submission, which tells the agent validation will not fetch remote content.

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 sentences, front-loaded with the core action and scoping qualifier; no filler or restatement of the name.

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?

No output schema exists, so return values need not be described, and annotations carry the safety story. However, the completely untyped 'submission' parameter and the unaddressed overlap with preflight_submission leave real gaps for an agent trying to call this correctly.

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 both parameters are untyped at the property level, so the description must compensate. It clarifies that 'documents' are optional caller-supplied text, but says nothing about the shape or role of the 'submission' parameter, which is the primary input.

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+resource ('Validate a submission') plus a scope qualifier ('without publishing') that signals a dry run. It does not distinguish itself from the very close sibling preflight_submission, which prevents a 5.

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 phrase 'without publishing' hints at a pre-publish check, but there is no explicit when-to-use, when-not-to-use, or named alternative. With preflight_submission and submit_service in the sibling list, the agent gets no help choosing between near-identical tools.

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