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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It does not state whether the tool is read-only, how filtering behaves, what the output looks like, or any side effects. This is insufficient for an unannotated tool.

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?

The single run-on sentence is not well-structured and front-loads little useful information. The title 'The options' contributes no value, and the description is vague enough that the clarity cost outweighs its brevity.

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 tool with no annotations, no output schema, and 0% parameter coverage, this description fails to explain return value, parameter semantics, or usage context. An agent would be guessing about filterKey and the overall 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 0%, and the description only clarifies that filtering is by 'tag value' (likely mapping to filterValue). The purpose and format of filterKey remain entirely unexplained, leaving the agent to guess how to construct a valid call.

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?

The description identifies a resource ('the options' in FSM software for UK multi-engineer operations) and hints at what it returns (name, best-for, tags), but it lacks an explicit verb. It reads as a noun phrase rather than stating an action like 'list' or 'compare', so an agent must infer the operation.

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 guidance is given on when to use this tool versus siblings like compare_criteria or compare_table. The optional tag filter is mentioned, but there is no context about when filtering is appropriate or what problem this tool solves.

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