list_audio_effects

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

With no annotations, the description carries the full burden. 'Read' implies read-only, but nothing is said about whether the catalog is static or account-specific, whether results are paginated, or what the effect entries contain. For a zero-annotation tool this leaves the behavioral profile largely undisclosed.

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?

A single front-loaded sentence with no filler. It is efficient, though the lone ambiguous adjective 'documented' is doing work that a short clarifying clause could have done better.

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?

The tool is simple (no params, no output schema, no nested objects), so the definition is nearly adequate. Missing are the shape of the returned catalog and its relation to the sound-effect generators, which an agent would need to use the results meaningfully.

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 no parameters, so per the baseline this scores 4. The description correctly implies a no-argument call rather than hinting at filters that do not exist in the 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 and resource: 'Read the documented audio effects catalog.' An agent can distinguish this from siblings like get_sound_effect_presets or generate_sound_effect. It stops short of 5 because the word 'documented' is unexplained (documentation vs. runtime catalog?) and no sibling is named.

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 pointer to alternatives such as get_sound_effect_presets. The agent must infer whether this is a discovery step before calling a generator or a standalone lookup.

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