Tool Scores

• aetherwave_reframe_imageA
  4.2/5.0
  Behavior4/5

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

  Annotations indicate non-readonly and non-destructive behavior. The description adds valuable transparency: it specifies the outpainting approach, speed tiers with credit costs, and that it returns a URL. No contradictions with annotations.

  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?

  Three sentences, each purposeful: first defines the core action, second lists required parameters, third details optional parameters with costs. No redundant 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 description covers inputs, behavior (outpainting), optional parameters, and output (URL). It lacks details on potential limitations (e.g., image size constraints) but is sufficiently complete for typical use given the tool's moderate complexity.

  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%, but the description enhances understanding by providing examples for aspectRatio ('16:9', '9:16', etc.) and clarifying the meaning of each speed tier with its credit cost. This goes beyond the schema's basic descriptions.

  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 uses a specific verb ('reframes an image to a new aspect ratio') and resource ('image'), and clearly differentiates from the sibling 'aetherwave_reframe_video' tool. It states the intelligently outpainting behavior, making the purpose unmistakable.

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

  Usage Guidelines3/5

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

  Well-structured with headings and bullet points. Every sentence adds value. Slightly long but justified by complexity. Front-loaded with core action, then detailed model guide.

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

  Completeness5/5

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

  Given 9 parameters, openWorldHint=true, and no output schema, the description is thorough. Explains return behavior, default model, cost, time, and caveats. Covers all needed context for an agent to use correctly.

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

  Parameters5/5

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

  Despite 100% schema coverage, description adds significant value: explains default model, cost, output count, speed, and model trade-offs. For imageUrl, warns about clean URLs. For model, provides detailed usage scenarios beyond schema.

  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?

  Title and description clearly state it edits an existing image using AI with a text prompt. The verb 'edit image' and resource 'public imageUrl plus prompt' are specific. Distinguishes from siblings like generate_image, remove_background, etc.

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

  Usage Guidelines5/5

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

  Provides an explicit model selection guide with when to use each model, default behavior, and fallback. Includes a concrete instruction: 'If the user simply says "edit this image" with no other signal, default to grok-imagine-i2i.'

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

  4.9/5.0
  Behavior5/5

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

  Annotations are minimal (readOnlyHint false, etc.), but the description adds critical behavioral context: polling with 8-minute timeout, default model fallback, cost per second, audio inclusion, cost impact of resolution/duration. No contradictions with annotations.

  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 long but well-structured with clear sections (model selection guide, audio, cost framing). Every sentence adds value; however, length could be slightly trimmed without losing clarity. Front-loaded with core behavior.

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

  Completeness5/5

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

  Given the complexity (8 parameters, many models, no output schema), the description is remarkably complete. It covers model selection, cost, audio, I2V requirements, and polling behavior, leaving no major gaps for the agent.

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

  Parameters5/5

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

  Schema coverage is 100%, but the description adds significant meaning beyond the schema itself. It explains default model, duration ranges per model, resolution default, requirement of imageUrl for I2V, mode only for Grok Imagine, and maps model selection to parameters.

  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 clearly states it generates a short-form video from text or text+image. It distinguishes itself from sibling tools like generate_image and reframe_video by specifying T2V and I2V modes and providing a detailed model selection guide.

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

  Usage Guidelines5/5

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

  The description provides an extensive model selection guide with explicit signals for when to use each model (e.g., 'highest quality' -> veo3.1-quality). It also advises when to ask the user (cost >100 credits, ambiguous 'best'). This is exemplary usage guidance.

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

• aetherwave_list_master_presetsA
  5/5.0
  Behavior5/5

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

  Annotations declare read-only and open-world hints. The description adds that it returns exactly 12 presets with specific styles and values, complementing the annotations without contradiction.

  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?

  Two concise sentences with front-loaded purpose, plus a list of preset styles. Every sentence is informative and there is no fluff.

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

  Completeness5/5

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

  Given zero parameters and no output schema, the description covers all necessary context: what is returned, when to call, and why. No gaps remain for this simple listing tool.

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

  Parameters5/5

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

  No parameters exist (schema coverage 100%), so no param info needed. The description fully communicates what the tool outputs, which is the only relevant semantic information.

  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 clearly states the tool returns all AI mastering presets with specific details (LUFS, tags, descriptions, difficulty). It distinguishes from the sibling tool 'aetherwave_master_audio' by indicating when to call this one first.

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

  Usage Guidelines5/5

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

  Explicitly tells when to use: 'Call this before master_audio when you don't know which preset fits the track.' Also mentions matching distribution target via LUFS values.

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