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 covered. The description adds nothing beyond that: it restates the HTTP verb/path and says nothing about permissions, error behavior when the ID is unknown, or what the fetched reaction contains.

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 the core action front-loaded and zero padding. The brevity is appropriate, though the second fragment merely echoes the REST path rather than adding agent-relevant information.

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?

With no output schema and no indication of the returned record's shape, the description is incomplete for an agent needing to consume the result. It also fails to disambiguate the tool from a large cluster of similarly named get_*_id siblings.

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% for the single `id` parameter, so the description must compensate. 'By ID' does indicate the identifier selects a code reaction, but gives no format (UUID, numeric, slug) or source for obtaining the ID, so it only marginally exceeds the bare schema.

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 (Get) and resource (code reaction) scoped by ID, which distinguishes it from the list-style sibling get_strategy_reaction_code. However, it never differentiates itself from the many near-identical siblings such as get_strategy_reaction_llm_id, get_strategy_code_id, or get_public_code_reaction, leaving the 'strategy reaction code' domain 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 when-to-use guidance, no prerequisites, and no named alternatives. The agent must infer from the name alone that this is the single-record fetch counterpart to get_strategy_reaction_code and get_strategy_reaction_code_total.

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