get_sequence_spawnables

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is fully covered. The description adds only the shape of the returned data; it does not mention pagination, error behavior when the sequence is missing, or ordering.

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, verb and resource front-loaded, with no filler. The return-shape enumeration is dense but justified because there is no output schema, though the standalone 'Returns:' line reads a touch boilerplate.

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 one simple parameter, full annotation coverage, and no output schema, the description supplies the missing return contract (field names plus spawnable_count), which is exactly what an agent needs to consume the result. Only optional detail like ordering or empty-sequence behavior is absent.

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 100% with a single documented parameter (sequence_name), so the schema already carries parameter meaning and the baseline of 3 applies. The description adds no extra syntax, format, or lookup-vs-path nuance for sequence_name.

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 ('List') and resource ('spawnables in a level sequence') plus the identifying fields returned. It implicitly distinguishes itself from get_sequence_possessables because spawnables are a distinct UE concept, but it never names the closest sibling to make the boundary explicit.

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 naming of alternatives. The presence of get_sequence_possessables, get_sequence_bindings, and set_spawn_ownership in the sibling list makes the missing differentiation notable, but the description says nothing about when this tool is the right one.

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