batch_analyze

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

No annotations are provided, so the description must disclose behavioral traits. It mentions progress tracking (indicating possibly async/long-running) but does not specify whether it is read-only, destructive, or any error/rate-limit behavior.

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?

One sentence that is concise and front-loaded with key action and differentiator. No fluff, but could be slightly more structured by separating purpose from feature.

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 the tool has 4 parameters, many siblings, and no output schema, the description is too minimal. It omits return value format, how progress tracking works, and relationship to other tools like analyze_page_speed.

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 clear parameter descriptions; the description does not add parameter-level detail. However, it adds value by mentioning progress tracking, which is not in the schema. Baseline 3 is appropriate.

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 'Analyze performance for multiple URLs' with a unique feature 'progress tracking'. It distinguishes from sibling tools like analyze_page_speed that handle single URLs, but does not explicitly name them.

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 batch_analyze versus other analysis tools, prerequisites, or context of use. With many sibling tools, this omission hinders correct invocation.

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