compare_before_after

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

No annotations are provided, so the description must convey behavioral traits. It only says 'compare and summarize', with no mention of side effects, authorization needs, rate limits, or any limitations. This is minimal behavioral disclosure.

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 sentence with no fluff, but it omits important details. It is concise but not adequately informative.

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 comparison tool, the description should explain the output format or criteria for improvement/gaps. It only vaguely mentions 'summarize improvements vs remaining gaps', leaving agents to guess the output structure. The sibling tool further calls for differentiation which is missing.

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 0% (no parameter descriptions). The description adds the phrase 'two README markdown strings', which maps to the parameters 'original' and 'improved', but does not provide expected format, constraints, or examples. This is insufficient compensation for the missing schema descriptions.

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 explicitly states the verb 'compare', the resource 'two README markdown strings', and the outcome 'summarize improvements vs remaining gaps'. It clearly distinguishes from sibling tool 'suggest_readme_improvements' which likely focuses on suggesting improvements rather than comparing two versions.

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 implies usage when an original and improved version are available, but provides no explicit guidance on when to use this tool versus the sibling 'suggest_readme_improvements', nor any exclusions or prerequisites.

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