getMonsters

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions filtering, sorting, and pagination but doesn't describe important traits like whether this is a read-only operation, what happens with invalid filters, rate limits, authentication requirements, or the format of returned results. For a list retrieval tool with zero annotation coverage, this leaves significant gaps.

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 description is a single, efficient sentence that front-loads the core purpose ('Get a list of monsters') and then succinctly lists the key capabilities. Every word earns its place with no redundancy or unnecessary elaboration.

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?

Given no annotations and no output schema, the description is incomplete for a tool with four parameters and nested objects. It doesn't explain what the returned list looks like, how errors are handled, or important behavioral aspects like default values or constraints. For a list retrieval tool with filtering capabilities, more context is needed to be fully helpful.

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 100%, so the schema already documents all four parameters thoroughly. The description adds minimal value by mentioning 'optional filtering, sorting, and pagination' which aligns with the schema but doesn't provide additional semantic context beyond what's already in the parameter descriptions. This meets the baseline for high schema coverage.

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 clearly states the verb ('Get') and resource ('list of monsters'), making the purpose immediately understandable. It distinguishes itself from siblings like getMonsterById or getMonsterByName by indicating it returns a list rather than a single entity. However, it doesn't explicitly differentiate from getMonsterByHabitat which also involves filtering.

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?

The description implies usage through 'optional filtering, sorting, and pagination', suggesting this tool is for general queries rather than specific lookups. However, it doesn't explicitly state when to use this versus alternatives like getMonsterByHabitat or getMonsterById, nor does it provide any exclusions or prerequisites for usage.

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