spraay_free

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

Annotations already declare readOnlyHint and openWorldHint. Description adds 'Free to call' and 'Read-only', which aligns but doesn't provide new behavioral context beyond annotations. No contradictions.

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?

Very short description (two sentences) with no wasted words. However, the first sentence 'Free tier catalog' is too minimal and could be improved without increasing length.

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 existence of an output schema (not shown) and full parameter coverage, the description fails to explain what the catalog returns or how it relates to other free tools. Incomplete for understanding the tool's full scope.

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% for the single 'params' parameter. The description reiterates that parameters are passed as JSON string, adding no new meaning beyond schema.

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?

Description states 'Free tier catalog' which indicates a general resource, but given many specific spraay_free_* siblings, the purpose is ambiguous. Does it list available endpoints or provide free-tier data? It lacks specificity to distinguish from sibling tools.

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 tool vs the many spraay_free_* siblings. Does not state when not to use it or what scenarios are appropriate. The description merely provides usage instructions for the params argument.

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