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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the agent knows this has side effects but is non-destructive; the description usefully adds that the side effect is publishing a public link. It does not disclose whether an existing link is reused or a new one issued, whether the link can be revoked, or that sharing makes audit data publicly accessible — meaningful gaps for a share/publish operation.

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?

A single front-loaded sentence with no filler; the dual behavior (create vs. return) leads and the scope qualifier follows. Nothing could be removed without losing meaning.

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 publishing tool with no output schema, the description should clarify what comes back (a URL string?) and whether the link is stable across calls or newly minted each time. It conveys the artifact being produced but leaves the return contract and link lifecycle ambiguous.

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%, with audit_id already documented as 'Completed mobile audit ID' and the context parameter fully specified in-schema. The description adds only the confirmation that the audit must be complete, which duplicates rather than extends the schema, so baseline 3 applies.

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 names a specific verb pair ('Create or return') and a specific resource ('the public share link for a completed Mobile Readiness Audit'), which clearly separates it from reading tools like get_mobile_audit_status or get_mobile_audit_evidence. It stops short of naming any sibling tool explicitly, so the differentiation is implicit rather than spelled out.

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 word 'completed' implies a prerequisite state for the audit, which is useful implied guidance. However, there is no explicit statement of when to call this instead of list_mobile_audits, get_mobile_audit_evidence, or render_mobile_audit_report, and no when-not guidance.

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