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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds only the HTTP route string, providing no behavioral detail on pagination, scoping, or result shape that the annotations don't already imply.

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; nothing is padded. The trailing 'GET /api/v2/strategy/reaction/code' is low-value for an agent 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 parameterless list tool with covered annotations and no output schema, the description is minimally viable but leaves the critical distinction unresolved: whether this returns the caller's own strategy code reactions versus the public ones exposed by list_all_public_code_reaction. That scope question is the main thing an agent needs here.

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 and the schema has no properties, so per the baseline there is nothing for the description to clarify. It does not misuse or misstate any parameter space.

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 verb and resource ('Get all code reactions'), but omits the 'strategy' scoping that its own name carries and never distinguishes it from close siblings like get_strategy_reaction_code_id, get_strategy_reaction_code_total, or list_all_public_code_reaction. An agent can infer this is a list endpoint, but 'all' is ambiguous about whose reactions are returned.

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 at all. With ~10 sibling reaction/strategy tools (single-id getters, public lists, totals, folders), the description never says when this collection getter should be chosen over them.

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