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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond restating the mutation and echoing the HTTP verb/path; it doesn't say what the update affects or that the body is optional.

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 and front-loaded, but the second sentence (the raw endpoint path) largely duplicates what the name already conveys rather than earning its place.

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?

A mutation tool with a nested body object, no output schema, and no annotations covering reversibility or permissions. The description omits what the update does, what happens to unmentioned fields, and the auto-generated-name behavior.

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 only 50%. The description gives no parameter meaning at all, leaving the 'name is auto-generated if omitted' behavior and the id semantics entirely to the schema without compensation in prose.

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 (update) and resource (LLM reaction folder), which separates it from the sibling put_strategy_reaction_llm_id that updates a reaction rather than a folder. Clear but relies on the tool name for finer differentiation.

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, prerequisites, or alternative guidance is given. The only context is the raw HTTP method and path, which does not tell an agent when to prefer this over post_strategy_reaction_llm_folder or put_strategy_reaction_llm_id.

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