Tool DescriptionsC

Average 2.2/5 across 3 of 3 tools scored.

Server CoherenceB
Disambiguation5/5

Each tool targets a distinct media type (image, video, music) with no overlap, making them clearly distinguishable.

Naming Consistency2/5

Two tools use the 'agent_' prefix (agent_image, agent_video) while the third uses 'create_' (create_music), showing inconsistency in naming pattern.

Tool Count3/5

With only 3 tools, the set is lean but may be appropriate for a focused media creation service; however, the server name 'catalog' suggests broader functionality that would typically require more tools.

Completeness2/5

The tools only cover creation of three media types, missing essential catalog operations like listing, searching, or managing creations, which are implied by the server name.

agent_imageCInspect

agent_image — $0.05 USDC via x402 on Base (chain 8453).

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

Behavior2/5

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

With no annotations, the description adds some behavioral info (cost and payment method), but fails to disclose other important behaviors such as error handling, rate limits, or output format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short (one sentence), which is concise, but omits critical information about what the tool does, making it less useful despite brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having no parameters and no output schema, the description fails to explain the tool's action or return value, leaving the agent without sufficient context to use it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters and the schema is fully covered (100% trivially). The description does not need to explain parameters, so it adequately fulfills this dimension.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description implies image generation via the name 'agent_image' and mentions a cost, but does not explicitly state the action (e.g., 'Generate an image'). It is somewhat clear but lacks direct statement of purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus siblings like agent_video or create_music. The cost hint provides minimal context but no explicit usage instructions.

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

agent_videoCInspect

agent_video — $1.50 USDC via x402 on Base (chain 8453).

ParametersJSON Schema
NameRequiredDescriptionDefault
seedNoOptional random seed for reproducible renders.
modelNoOptional model preset variant. Leave unset for the default.
promptYesNarrative or visual prompt to drive the music video concept.
asyncModeNoIf true, return immediately while the video renders asynchronously.
resolutionNoTarget rendering resolution.
aspectRatioNoDesired frame aspect ratio.
durationSecondsNoClip length in seconds (default 8).
Behavior2/5

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

Description discloses the cost and chain, but with no annotations, it leaves out important behavioral traits like idempotency, rate limits, or the behavior of asyncMode. The brief description adds minimal behavioral info.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise but at the expense of clarity. It is not structured to highlight key information beyond pricing.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 7 parameters, no output schema, and no annotations, the description is extremely lacking. It only provides pricing, leaving out behavior, return values, and usage context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers all 7 parameters with descriptions, so baseline is 3. The description adds no extra meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description only mentions a cost and payment method, not the actual function. From the input schema, it appears to generate a music video, but the description fails to state this explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus sibling tools like agent_music or cover. The description does not provide context for selection.

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

create_musicDInspect

create_music — $0.20 USDC via x402 on Base (chain 8453).

ParametersJSON Schema
NameRequiredDescriptionDefault
tagsNoComma-separated keywords to tag the generated file.
styleNoSpecific musical style or genre tag (e.g., 'Hip Hop', 'Ambient', 'Rock'). Helping the AI focus on a specific sound.
lyricsNoYour custom lyrics. Required if custom_mode is true.
promptYesDescribe the song you want to create. Include genre, mood, instruments, and any specific vibe. Example: 'Upbeat 80s synthwave with driving bass and neon atmosphere' or 'A melancholic acoustic guitar ballad about rain'.
custom_modeNoSet to true to use your own lyrics provided in the 'lyrics' field.
vocal_genderNoPreferred gender for the vocalist ('m' for male, 'f' for female).
durationSecondsNoDuration of the track in seconds. Defaults to a full-length song.
make_instrumentalNoIf true, generates a track without vocals.
Behavior2/5

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

Despite no annotations, the description only discloses cost/payment method. It does not disclose that the tool generates AI music, any destructive actions, or required authentication. The key behavioral aspect (generation) is missing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short but misses essential purpose and usage context. Conciseness is achieved at the expense of completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 8 parameters and no output schema or annotations, the description fails to explain what the tool does, its inputs, or expected outputs. It is severely incomplete for a tool of this complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description adds no value beyond schema. Baseline 3 is appropriate as description does not enhance parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description merely repeats the tool name and adds payment details ('$0.20 USDC via x402 on Base'). It does not explicitly state that it generates music or what the output is, relying solely on the name for purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use create_music vs sibling tools (agent_music, agent_video). The description lacks context about scenarios or limitations.

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