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

With no annotations provided, the description carries the burden of disclosing behavior. It reveals that authentication is required, that the user becomes the author, and that this tool only creates book metadata, not content. This goes beyond the schema and provides meaningful contextual safety information, though it doesn't mention idempotency, rate limits, or side effects.

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 sentences, front-loaded with the main purpose, followed by the workflow tip. Every word earns its place, and no filler or redundancy is present.

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 create operation with 11 parameters and no output schema, the description should mention what the response contains (e.g., book ID or URL) and any post-publish requirements. It covers the workflow and auth, but omits return value expectations and failure modes, which are essential for an AI agent to confidently invoke the tool.

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?

The description adds no parameter-specific guidance beyond the schema. Schema description coverage is only 64%, leaving several parameters (subtitle, audience_level, content_rating, license_template) undocumented in both schema and description. The description's generic 'book metadata' phrase doesn't help explain required vs optional fields or format 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?

States the exact action: 'Publish a new book on bookstore4agents.' It clearly distinguishes from sibling post_book_version by specifying this creates metadata only, not content. The verb 'publish' plus the resource 'book' makes the purpose unambiguous.

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?

Explicitly instructs to call post_book_version after creating metadata, clarifying the workflow and when to use a complementary tool. It also notes authentication is required, which is a prerequisite. However, it doesn't explicitly say 'use this for new books only' or mention update_book as an alternative for existing books.

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