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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that: it doesn't say the update is a status flip, that it targets an existing reaction, or what the effect of ACTIVE vs INACTIVE is. With annotations present the bar is lower, but this adds no context at all.

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 terse fragments with no filler and the action front-loaded. It avoids waste, though the brevity edges toward under-specification rather than genuine economy.

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 mutation with a nested body, no output schema, and 0% schema description coverage, the definition is too thin. It leaves unstated whether the reaction must already exist, whether the change is reversible, and how the enum values map to 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 description coverage is 0% across 2 parameters including a nested body object, so the description must compensate and does not. It only implies that {id} identifies the reaction and 'status' is what changes, without explaining the ACTIVE/INACTIVE enum semantics or the body structure.

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?

"Update LLM reaction status" gives a specific verb and resource, so the action is understandable. But it essentially restates the tool name (put_strategy_reaction_llm_id_status) and offers no differentiation from close siblings like put_strategy_reaction_llm_id or put_strategy_reaction_llm_id_reset. Vague on scope relative to the family.

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?

There is no when-to-use guidance and no reference to alternatives, despite a large family of put_*_id_status and put_strategy_reaction_llm_id* tools. The agent must infer that this is the status-toggle variant from the name alone.

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