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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the write/safety profile is covered. The description only restates the HTTP verb and path, adding nothing about auth, name uniqueness, the auto-generated name fallback, or the response — no value beyond structured data.

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 short sentences with the action front-loaded and zero padding. The trailing HTTP path is borderline redundant with the POST verb but is compact enough not to hurt.

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 creation tool with no output schema and a thin input schema, the description should at least indicate what is created and where it lands (root vs. nested folder). It omits response shape, scoping, and auth requirements entirely.

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 reported at 0%, so the description carries the burden, yet it says nothing about the single body/name parameter or that it is optional. The schema's inline note about auto-generation is the only place that information exists.

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 a specific verb+resource combination ('Create a new code reaction folder') that lets an agent distinguish it from post_strategy_reaction_code or post_strategy_reaction_llm_folder by name. It stops short of any explicit sibling differentiation in the prose itself.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as post_strategy_reaction_code or post_strategy_reaction_llm_folder. The agent must infer everything from the tool name alone.

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