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

No annotations are provided, so the description carries the full behavioral burden. It does not state that this is a read-only/analysis operation, whether it writes any files, whether results are deterministic, or how the extracted style feeds into sibling tools like aseprite_apply_palette. Only the output categories are disclosed.

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; the key verb and outputs come first. It is efficient, though the output list runs slightly long for such a short description.

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?

For a no-annotation, no-output-schema tool with 4 params, the description is only adequately complete: it names outputs but omits when to use it, what happens to the width/height params, and how the analysis is consumed downstream. An agent can call it but has gaps.

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 50% already. The description's mention of 'reference image or text prompt' loosely maps to referenceImage and prompt, but the width/height parameters (defaulting to 64) are never explained, and the enumerated outputs do not clarify what the two dimension params do.

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?

Specific verb ('Extract') plus the concrete artifacts produced (palette HEX, shading style, outline rules, grid specs) and the input sources (reference image or text prompt). It is easy to distinguish from siblings like aseprite_create_sprite or aseprite_apply_palette, though it never names those alternatives.

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, no mention of alternatives. The phrase 'from a reference image or text prompt' hints at input modes but does not say when an agent should analyze style versus just creating a sprite directly.

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

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

No annotations are provided, so the description carries the full disclosure burden, yet it only implies mutation. It never says whether colors are remapped/quantized in place, whether the source file is overwritten or a new file written, or what the result looks like.

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; the action and target come first. It is efficient, though arguably too terse given the tool's mutation semantics.

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?

For a file-mutating tool with no annotations and no output schema, the description omits critical operational detail: in-place vs new-file behavior, palette conflict handling, and any overwrite risk. Not sufficient for an agent to invoke it safely beyond the happy path.

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 already 100%, and the description merely repeats the preset examples ('pico-8', 'endesga-32', 'gameboy') that the schema already lists. It adds no meaning about customPalette format, precedence, or interaction between the two palette parameters.

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 ('Apply') and resource ('a color palette preset ... to a sprite'), and the example presets make the operation concrete. It is distinguishable from siblings like aseprite_draw_pixels or aseprite_convert, though it never explicitly contrasts with them.

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 guidance on when to use this tool rather than alternatives (e.g. aseprite_convert or aseprite_draw_pixels), and no exclusions or prerequisites. Nothing tells the agent whether palettePreset and customPalette are mutually exclusive.

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

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

No annotations are provided, so the description carries the full behavioral burden. It says nothing about whether outputPath is overwritten if it exists, whether the input sprite must be closed/valid, how animated frames are handled in the conversion, or what errors occur on invalid scale values. Only the core transform is disclosed.

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 covering the action, the formats, and the optional scaling feature, with no filler. It is efficient, though it omits a parenthetical clarifying frameRange, which would have been cheap to include.

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?

For a file-writing tool with no annotations and no output schema, the description does not state what is returned or how output is reported, nor does it cover overwrite behavior or frame-range interaction. It covers the core purpose but leaves meaningful gaps for a mutation-style tool.

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 description coverage is 100%, so each of the four parameters is already documented in the schema, making a baseline of 3 appropriate. The description adds only marginal value by giving scaling examples (2x, 4x, 8x) and never mentions frameRange, whose semantics ('1,4') would benefit from explanation.

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?

The description gives a specific verb ('Convert') and resource ('sprite file') and enumerates the target formats (.png, .gif, .aseprite), plus the optional scaling capability. It is clear on its own, but it does not differentiate itself from sibling tools like aseprite_export_spritesheet, which also produce output files from a sprite.

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?

There is no guidance on when to use this conversion tool versus aseprite_export_spritesheet, aseprite_inspect_sprite, or the GUI opener. No prerequisites, no mention of which formats are valid inputs, and no conditions under which scaling should be applied are stated.

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

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

With no annotations, the description carries the full behavioral burden. It says 'Add' frames, implying mutation of an existing sprite, but never states whether the file must exist, whether existing frames/tags are preserved or overwritten, whether the operation is reversible, or what is returned.

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 covering the three core actions with an inline example; there is no padding. It is efficient, though the parenthetical examples add little beyond the schema's own enum/examples.

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?

For a 5-parameter mutating tool with no annotations and no output schema, the description omits file preconditions, overwrite semantics, and any return information. The unit mismatch further undermines completeness.

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%, so the baseline would be 3, but the description states durations are in milliseconds ('frame durations (ms)') while the schema defines duration in seconds (e.g. 0.1 for 100ms). This conflicting unit is actively misleading and could cause an agent to pass wrong values.

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?

The description names a concrete verb+resource (create animation) and enumerates the three operations performed: adding frames, setting durations, and defining tags with examples. It is clearly distinguishable from siblings like aseprite_create_sprite or aseprite_draw_pixels, though it never explicitly contrasts itself with them.

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 (e.g. that the sprite file at filepath must already exist, or how it relates to aseprite_create_sprite), and no exclusions or alternatives. An agent must infer when this is the right tool.

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

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

No annotations are provided, so the description carries the full behavioral burden. It implies a file-creating mutation but doesn't disclose side effects like file overwrite behavior, permissions needed, or what happens if the file exists. It also doesn't mention whether the sprite is opened in the GUI or kept in memory.

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, efficient sentence that front-loads the core action and lists key configurable aspects without any wasted words.

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?

For a tool with eight parameters, no output schema, and no annotations, the description is too sparse. It lacks essential behavioral details, usage context, and edge cases, making it less helpful than it could be for an agent to call correctly.

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 description coverage is 100%, so the schema already documents all eight parameters thoroughly. The description mentions custom dimensions, color mode, layers, frames, and palette, which adds minimal value beyond the schema but doesn't provide additional syntax or format details.

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 (Create) and resource (sprite file), and lists the configurable dimensions. The scope is clear, though it doesn't explicitly distinguish itself from siblings like aseprite_convert or aseprite_create_animation beyond the creation aspect.

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 guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, such as whether Aseprite must be installed or if the file must not already exist, nor does it point to related tools for animations or conversions.

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

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

No annotations are provided, so the description carries the full burden. It reveals that this is a mutation on an existing sprite, but says nothing about overwrite semantics for the target pixels, what happens if the named layer/frame is absent, whether existing cel content is preserved, or whether the file is saved afterward. The clearCel parameter hints at destructive behavior but the description never clarifies it.

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 naming the action, the two input modes, and the target scope, with no filler or redundancy.

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?

For a six-parameter mutation tool with nested objects, no output schema, and no annotations, one sentence is not enough. It omits the mutually exclusive nature of pixels vs matrix, the role of offsetX/offsetY, and the effect of clearing the cel, all of which an agent needs to invoke it correctly.

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 description coverage is 100%, so every parameter including the nested matrix fields is already documented in the schema; baseline 3 applies. The description merely echoes 'layer and frame' and adds no extra semantics such as how offsets interact with the sprite bounds or what a 'transparent' color value does.

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 (draw) plus the two resource forms (pixels or 2D character matrix) and the exact target (a layer and frame of an existing sprite). This clearly distinguishes it from siblings like aseprite_create_sprite or aseprite_export_spritesheet, which operate at a different level.

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?

The phrase 'existing sprite' implies a prerequisite but there is no explicit when-to-use guidance, no mention of when to prefer the matrix form over the pixels form (a genuine either/or decision in the schema), and no reference to alternatives such as composing art via aseprite_run_lua or an animation tool.

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

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

No annotations are provided, so the description carries the full burden. It implies file writes (creating .png and .json outputs) but says nothing about overwrite behavior, required Aseprite runtime availability, whether the source file is modified, or error conditions. For a write-producing tool this is a significant gap.

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 efficient, front-loaded sentence naming the key outputs; nothing is wasted. It is slightly thin for a tool with 11 parameters, but the structure itself is clean.

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 11 parameters, 45% schema coverage, no annotations, and no output schema, the description should do much more to explain the export configuration surface (layout modes, padding, tag/layer splitting). As written, an agent cannot confidently invoke it beyond the two required paths.

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 description coverage is only 45% across 11 parameters, and the description only implicitly references the two output paths (sheetPath, dataPath). Undocumented parameters like splitTags, splitLayers, trim, and the three padding options receive no clarification in the description, so it fails to compensate for the coverage gap.

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 (export) and resource (sprite/animation into a packed spritesheet with .png texture and .json metadata), and names the output artifacts. It does not differentiate itself from siblings like aseprite_convert or aseprite_run_pipeline, so it falls short of a 5.

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 guidance on when to choose this over aseprite_convert or aseprite_run_pipeline, no prerequisites (e.g. requires an open/source .aseprite file), and no mention of when NOT to use it. Usage must be inferred from the name alone.

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

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses the returned contents (path, version, capability status) and implies a non-mutating diagnostic, but says nothing about failure modes (e.g., whether it errors or returns a flag when Aseprite is not installed) or cost/latency of the scripting test.

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. Every clause earns its place by naming a distinct piece of information the tool retrieves.

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 no output schema, no annotations, and no parameters, the description is nearly sufficient for a simple diagnostic call. The only meaningful gap is failure behavior when Aseprite is absent, which an agent would want to know before building a pipeline on top of it.

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 zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies; the description correctly does not invent parameter guidance.

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?

The description names a specific verb ('Get') and a concrete resource ('Aseprite executable path, version'), plus a diagnostic side task ('test CLI/Lua scripting capability'). It is clearly distinct from action-oriented siblings like aseprite_convert or aseprite_draw_pixels, but it never explicitly says how it differs from aseprite_inspect_sprite or aseprite_run_lua.

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?

There is no statement of when to call this tool, no prerequisite context, and no alternative named. The agent can infer it is an environment/health-check tool, but nothing in the text tells it to run this before invoking the other Aseprite tools or when to prefer it over aseprite_run_lua for capability probing.

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

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

With no annotations, the description carries the full behavioral burden. 'Inspect' weakly implies a read-only, side-effect-free operation, but this is never stated, and there is no mention of error behavior for missing/invalid files or whether the file is locked or opened.

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?

One front-loaded sentence with zero filler that names the action, the target, and the returned data.

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?

For a simple one-parameter read tool with no output schema, enumerating the returned fields (dimensions, layers, frames, tags, palette) is genuinely useful. The main omission is guidance versus aseprite_get_info, which the description never addresses.

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% and the single filepath param is already documented. The description does add accepted input formats (.aseprite or image) beyond the schema's generic 'Path to the sprite file', but nothing about path resolution or relative paths.

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?

Clear verb 'inspect' plus specific resource 'sprite file' and an enumeration of what is read (dimensions, layers, frames, tags, palette). However, it does not distinguish itself from the near-identical sibling aseprite_get_info, leaving ambiguity about which tool to pick.

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, prerequisites, or alternatives are given. The presence of a sibling named aseprite_get_info that plausibly does the same thing makes this omission a real gap for tool selection.

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

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing beyond the action itself. It does not say whether a GUI/display environment must be running, whether the call requires a specific OS, whether it blocks or returns immediately, or what happens on failure — all material for a GUI-launching tool.

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; the key differentiator (GUI window) appears immediately. It is efficient, though it is arguably too terse to earn full marks given the missing behavioral detail.

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?

Simple one-parameter tool with no output schema needed, so the schema side is covered. However, the interaction with the environment (display availability, blocking behaviour) is undocumented, which is a real gap for a tool whose whole purpose is to surface a GUI window.

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?

With a single parameter at 100% schema description coverage, the schema already documents 'filepath' fully; the description adds no format, extension, or path-resolution detail beyond it. Baseline 3 is appropriate when structured data does the work.

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 concrete verb ('open') and resource ('.aseprite file'), and the phrase 'on your screen inside the Aseprite GUI window' clearly distinguishes it from headless siblings like aseprite_convert or aseprite_run_lua. It stops short of naming which sibling to use instead, so it doesn't reach a 5.

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?

There is no explicit when-to-use or when-not-to-use guidance. The word 'Directly' hints at an interactive/visual use case, but nothing tells the agent when this is preferable to a headless sibling such as aseprite_get_info or aseprite_export_spritesheet.

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

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

No annotations are provided, so the description carries the full behavioral burden. It mentions the headless environment and that scripts are 'arbitrary', but it does not disclose side effects, sandboxing, permissions, whether scripts can modify project files, or error/timeout behavior — all critical for arbitrary code execution.

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 sentence that is front-loaded with the core action and resource, with no wasteful clauses. Every word contributes to the purpose.

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?

For an arbitrary code-execution tool with no annotations and no output schema, the description is inadequate. It omits crucial context such as sandbox limitations, what APIs are available to the script, or what side effects are possible, leaving the agent unable to assess risk or expected behavior.

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 description coverage is 100%, so both parameters ('code' and 'params') are already documented in the schema. The description adds no syntax, format, or usage guidance beyond what the schema provides, making the baseline of 3 appropriate.

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 ('Execute') and resource ('arbitrary Lua script') within a named environment ('Aseprite headless environment'). It does not explicitly name or distinguish itself from siblings like aseprite_run_pipeline, though 'advanced custom workflows' hints at a general-purpose alternative to the dedicated tools.

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?

The phrase 'for advanced custom workflows' implies usage when dedicated tools are insufficient, but it never states when to prefer this over aseprite_run_pipeline or the many specific operation tools, nor any exclusions or prerequisites.

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

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

No annotations are provided, so the description bears full behavioral burden. It discloses the output layout (files grouped into /output/<folderName>/) which is useful, but says nothing about whether the pipeline overwrites existing folders, how long it takes, whether it can fail partway, whether it costs model calls, or what happens to openInGui. For a heavy multi-stage orchestrator with zero annotation coverage, this is a significant gap.

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 tight sentences: purpose and stage names first, then output location. No filler, well front-loaded.

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?

For an 8-parameter orchestrator with no annotations and no output schema, the description covers purpose and output folder but omits failure behavior, overwrite semantics, runtime expectations, and how outputs relate to sibling inspect/export tools. Adequate but leaves real operational gaps.

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 description coverage is 100%, so the schema already documents every parameter including defaults and examples. The description adds the output-path semantics tied to targetFolder/folderName, which is beyond the schema. Baseline would be 3, lifted slightly by that added folder-naming context.

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+resource: runs a named 3-stage multi-agent asset pipeline and lists the stages. It clearly distinguishes itself from atomic siblings like create_sprite or draw_pixels by being the orchestrating pipeline. It doesn't explicitly name sibling alternatives, but the scope is unambiguous.

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?

Implies usage (generate a full game asset from a prompt via a multi-agent flow), but gives no explicit when-to-use vs when-not, no comparison to running individual stage tools like aseprite_analyze_style first, and no note on cost/time of running the full pipeline.

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