agent_imageAInspect

AI image generation from a text prompt. Generate album and single cover art, podcast and video thumbnails, social and campaign graphics, concept art, storyboard frames, product shots, and article illustrations. Returns one hosted still image as PNG or JPEG in square, portrait, or widescreen framing (1:1, 4:5, 9:16, 16:9, 21:9). Async by default: poll the returned pollUrl for imageUrl, or pass ?async=false to block. — $0.15 USDC via x402 on Base (chain 8453).

ParametersJSON Schema
NameRequiredDescriptionDefault
promptYesImage description — subject, style, composition.
asyncModeNoReturn immediately with a jobId while the render runs. Can only switch async on: false is the same as omitting it, so a paid call stays asynchronous; ?async=false is the only way to force a blocking call.
aspectRatioNoAspect ratio, e.g. '1:1', '16:9', '9:16'.

TDQS

A4.6/5.0
Behavior5/5

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

With no annotations provided, the description carries the full disclosure burden and does so well. It reveals async-by-default behavior, the polling mechanism (pollUrl → imageUrl), the blocking alternative (?async=false), output format (one hosted PNG/JPEG), supported aspect ratios, and pricing/chain details ($0.15 USDC on Base). This gives the agent a reliable mental model of how the call behaves.

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

Conciseness5/5

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

The description is three dense sentences with no filler. It front-loads the core purpose first, then use cases, output behavior, async semantics, and cost. Every sentence contributes operational or selection-relevant information.

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

Completeness4/5

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

The tool has no output schema and no annotations, so the description must supply essential invocation and return details. It covers purpose, output format, aspect ratios, async polling, blocking option, and cost. The only notable gap is how the x402 payment flow is initiated or handled, but the description provides enough for an agent to make the call and interpret the response.

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?

Schema coverage is 100%, so the baseline is 3. The description adds value beyond the schema by listing the full set of supported aspect ratios and reinforcing the async/blocking behavioral distinction. It does not deeply elaborate on prompt nuances, but the schema already describes prompt as 'subject, style, composition.'

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

Purpose5/5

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

The description opens with a specific verb and resource: 'AI image generation from a text prompt.' It then enumerates concrete use cases (album art, thumbnails, concept art, product shots, etc.) that make the tool's scope unmistakable. The contrast with siblings agent_video and create_music is implicit but clear: this tool produces still images, not video or music.

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

Usage Guidelines4/5

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

The description gives clear context for when to use the tool through its list of image-generation use cases. It does not explicitly exclude alternatives or name sibling tools for video/music, but the domain separation is evident enough that an agent can route correctly. No explicit 'when not to use' guidance is provided.

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

agent_videoAInspect

AI video generation from a text prompt. Returns an 8-second 720p clip with native audio. Use for short-form video, b-roll, product shots, music-video visuals, social clips, and ads. Include sound cues (instruments, voices, weather, movement) since audio is generated from the scene; a silent scene renders near-silent by design. Async by default: poll the returned pollUrl for videoUrl, or pass ?async=false to block. — $4.99 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.
asyncModeNoReturn immediately with a jobId while the render runs. Can only switch async on: false is the same as omitting it, so a paid call stays asynchronous; ?async=false is the only way to force a blocking call.
resolutionNoTarget rendering resolution.
aspectRatioNoDesired frame aspect ratio.
durationSecondsNoClip length in seconds (default 8).

TDQS

A4.4/5.0
Behavior4/5

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

With no annotations, the description carries the full behavioral burden, and it does well by disclosing async-by-default behavior, pollUrl/videoUrl, the blocking override, native audio generation, and pricing. However, 'Returns an 8-second 720p clip' is stated as fixed even though the schema exposes durationSeconds and a 1024p resolution option, so it slightly overstates the default output.

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

Conciseness5/5

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

The description is compact, front-loaded with the core purpose, and every sentence adds value: output format, use cases, prompt strategy, async behavior, and cost. It avoids redundancy and is easy for an agent to scan.

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

Completeness4/5

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

The description covers the essential runtime behavior—default output, async flow, polling, blocking mode, audio considerations, and cost—without an output schema to rely on. It does not detail authentication, error cases, or the full set of param interactions, but the schema already documents the parameters and the core workflow is sufficiently complete.

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?

Schema coverage is 100%, so the baseline is 3. The description adds meaningful prompt guidance—include sound cues since audio is generated from the scene—and clarifies the default duration and resolution. This goes beyond the schema's field descriptions, particularly for the prompt parameter.

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

Purpose5/5

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

The description opens with a specific verb and resource: 'AI video generation from a text prompt.' It further clarifies the output—an 8-second 720p clip with native audio—and lists concrete use cases such as b-roll, product shots, and social clips. This makes it clearly distinct from sibling tools agent_image and create_music.

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

Usage Guidelines4/5

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

The description provides clear usage context by listing short-form video, b-roll, product shots, music-video visuals, social clips, and ads. It does not explicitly name when not to use this tool or contrast it with agent_image and create_music, but the video-specific framing makes the intended scope clear.

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

create_musicAInspect

AI music generation from a text prompt. Creates a complete original song with vocals, melody, and full arrangement as a finished MP3, not a loop or preview. Describe genre, mood, instrumentation, and tempo, supply your own lyrics, request an instrumental, or pin a style tag. Use for soundtracks under video, release-ready artist tracks, podcast and game themes, and demo sketches. Async: poll songId until model_version leaves 'pending'. — $0.50 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.

TDQS

A4.5/5.0
Behavior5/5

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

With no annotations, the description carries the full disclosure burden and does so well: it states the output format, async polling behavior (songId/model_version leaving 'pending'), and pricing/payment rails (USDC via x402 on Base). This goes well beyond the schema's field-level information.

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

Conciseness4/5

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

The description is front-loaded with the core purpose and every sentence carries weight—use cases, async behavior, and cost are all relevant. The first two sentences overlap slightly in saying this is text-prompt music generation, which keeps it just shy of a 5.

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

Completeness4/5

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

For a tool with no output schema, the description provides the necessary extra context: final MP3 output, async polling touchpoints, and payment details. It is terse about the actual poll mechanism and response shape, but the 100% input-schema coverage compensates for parameter-side gaps.

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 schema already documents all 8 parameters, so the baseline is 3; the description adds useful mapping like 'Describe genre, mood, instrumentation, and tempo' (prompt), 'supply your own lyrics' (custom_mode/lyrics), 'request an instrumental' (make_instrumental), and 'pin a style tag' (style). This enriches without duplicating schema detail.

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

Purpose5/5

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

The description identifies a specific verb and resource: AI music generation from a text prompt producing a complete original song as an MP3. It also differentiates from the sibling media tools by specifying vocals, melody, full arrangement, and 'not a loop or preview'.

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

Usage Guidelines4/5

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

It gives concrete, relevant use cases (soundtracks, release-ready tracks, podcast/game themes, demo sketches) and clarifies the output type. It does not explicitly name sibling alternatives or state when not to use this tool, so it falls short of a 5.

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

TDQS

A4.4/5.0
Disambiguation5/5

Each tool targets a distinctly different media type: image, video, and music. There is no overlap or ambiguity between generating a still image, a video clip, or an original song.

Naming Consistency3/5

Two tools follow the agent_ prefix pattern (agent_image, agent_video) while the third uses create_music, mixing conventions. The names are still readable, but the pattern is not fully consistent.

Tool Count4/5

Three tools is a lean but reasonable set for a media generation server. Each tool covers a meaningful content type and earns its place, though the server could arguably include additional related creation tools.

Completeness4/5

The surface covers the core generation needs for image, video, and music content. Minor gaps exist, such as no editing or asset management tools, but the core lifecycle of generating and receiving media is complete.
