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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, covering the safety profile. The description adds only the raw endpoint path, no details on return shape, pagination, or folder hierarchy, so it contributes little beyond the structured fields.

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 fragments with the purpose front-loaded, no wasted prose. The trailing 'GET /api/v2/...' path is largely redundant with the name but costs little.

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 simple zero-argument list endpoint with annotations covering safety and no output schema, the description is minimally adequate. It still omits whether results are hierarchical, paginated, or scoped to the authenticated user, which matters when several folder-listing siblings exist.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. Schema coverage is a nominal 100% with an empty properties object.

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 clear verb and resource ('Get all code reaction folders'), so an agent knows it is a listing operation. However, it never distinguishes itself from close siblings such as get_strategy_reaction_code_folder_root, get_strategy_reaction_code_folder_id, or get_strategy_code_folder, leaving the exact folder scope ambiguous.

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 versus the *_folder_root, *_folder_id, or get_strategy_reaction_code_total siblings, and no prerequisites are stated. The agent must infer context purely from the name.

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