direct.hf.create_sitelinks_set

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

No annotations provided, so the description carries full behavioral burden — and it says almost nothing. It doesn't disclose that apply/dry_run control whether changes are actually committed, doesn't state permission requirements, doesn't say whether an existing set is overwritten or a new one is created, and doesn't explain the return. For a mutation tool with zero annotation coverage, this is a major gap.

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 one sentence is short and front-loads the verb, which is good. But 'Human-friendly:' is a wasted qualifier that occupies half the text without informing the agent; trimming it would leave a cleaner imperative.

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?

A 5-parameter mutation tool with no annotations, no output schema, and only 40% schema coverage. The description should explain the apply/dry_run workflow and what sitelinks shape it expects, but instead provides a single sentence. This is inadequate for safe invocation.

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 40%, leaving apply, dry_run, and sitelinks undocumented in both schema and description. The description lists no parameters at all, so it fails to compensate for the three bare booleans/arrays — notably the apply/dry_run pair, whose semantics are essential for correct invocation.

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 (create) and resource (sitelinks set), so the action is identifiable. But 'Human-friendly:' is filler that adds nothing, and the description doesn't differentiate from siblings like direct.list_sitelinks, direct.hf.attach_sitelinks_to_ads, or direct.hf.create_callouts — all of which touch the same asset ecosystem.

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?

No guidance on when to use this versus direct.list_sitelinks, attach_sitelinks_to_ads, or raw_call. No preconditions stated. The presence of apply/dry_run booleans in the schema suggests a plan-then-apply workflow, but the description never mentions it.

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