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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the write-vs-read question is covered. The description adds nothing beyond restating the HTTP method and path: it does not say whether the change is reversible, whether permissions are required, or what effect ACTIVATE/INACTIVATE has on a running reaction.

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 no filler, front-loading the purpose before the endpoint. It is efficient, though the endpoint echo is redundant padding for an agent that already knows the tool name.

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?

This is a mutation tool with no output schema and minimal annotations, so the description should explain parameters, effect, and error/permission behavior. Instead it provides only a purpose sentence and the URL, leaving the agent under-informed for invoking it correctly among many similar sibling tools.

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%, so the description carries the full burden of explaining the two parameters, yet it mentions neither 'id' nor the status field. The only documentation of valid values is the nested enum inside the schema, which the description never references or explains.

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+resource combination ('Update code reaction status') and repeats the REST endpoint, so the agent knows it mutates a reaction's status. It does not, however, distinguish itself from close siblings such as put_strategy_reaction_code_id or put_strategy_reaction_code_id_reset, so the specific scope of 'status' versus other mutations is left implicit.

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 guidance on when to use this tool instead of put_strategy_reaction_code_id, put_strategy_reaction_code_id_reset, or put_strategy_reaction_code_id_public, all of which act on the same resource. No prerequisites or exclusions are given.

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