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

No annotations are provided, so the description carries full burden. It mentions 'fast indexing' and 'FREE', which hints at speed and cost, but lacks critical behavioral details: required permissions, rate limits, response format, error handling, or what 'fast' entails. For a submission tool with zero annotation coverage, this is a significant gap in transparency.

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 description is a single, efficient sentence: 'Submit URLs to search engines for fast indexing via IndexNow protocol — FREE'. It's front-loaded with the core purpose and includes key details (protocol, free). No wasted words, though it could be slightly more structured for clarity.

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?

Given no annotations, no output schema, and a submission tool with potential behavioral complexity (e.g., indexing effects, errors), the description is incomplete. It lacks details on outcomes, limitations, or integration context, making it insufficient for an agent to use the tool confidently without additional assumptions.

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 100%, so the schema fully documents the parameters (url and urls). The description adds no additional parameter semantics beyond implying batch submission via 'Batch of URLs' in the schema. Baseline 3 is appropriate as the schema handles the heavy lifting, but the description doesn't compensate with extra context like format examples or constraints.

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 clearly states the tool's purpose: 'Submit URLs to search engines for fast indexing via IndexNow protocol — FREE'. It specifies the action (submit), resource (URLs), and protocol (IndexNow), distinguishing it from SEO-related siblings like seo_meta, seo_schema, and seo_score. However, it doesn't explicitly differentiate from other indexing or submission tools (none present in siblings), so it's not a perfect 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 description provides minimal guidance: it implies usage for fast indexing via IndexNow and mentions it's free. However, it doesn't specify when to use this tool versus alternatives (e.g., other SEO tools in the sibling list), prerequisites, or exclusions. No explicit when/when-not instructions are given, making it inadequate for informed tool selection.

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