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

The description only states 'Add a node' with no disclosure of side effects, permissions, or behavioral traits like whether it modifies the scene file, requires the scene to be loaded, or what happens with optional parameters. Annotations provide no additional behavioral hints (no readOnlyHint or destructiveHint).

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?

The description is a single concise sentence with no wasted words. However, it sacrifices informativeness for brevity, which is acceptable but not excellent.

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?

Despite having 6 parameters (including a nested object) and no output schema, the description is extremely brief. It does not explain key aspects like parent node path handling, property constraints, or return behavior, leaving significant 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 100% with descriptions for each parameter, so the baseline is 3. The tool description adds no extra semantic meaning beyond what the schema already provides.

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 'Add a node to an existing scene' clearly identifies the action and resource, but does not differentiate from sibling tools like game_spawn_node or modify_scene_node, which may have overlapping functionality.

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. There is no mention of prerequisites, such as whether the scene must be open, or when to prefer game_spawn_node over add_node.

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 beyond the title, the description carries the full burden of behavioral disclosure. It does not explain side effects (e.g., file modification), permissions required, or what happens if the script already exists. The single sentence is insufficient for a mutation 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?

The description is very brief (8 words) and front-loaded with the verb. It is efficient but may be too terse, missing important context. Structure is adequate for a simple tool.

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?

Given the tool has 4 required parameters, no output schema, and a large set of sibling tools, the description is insufficient. It does not explain the 'headless' term, return value, or error conditions. More detail is needed for safe usage.

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

Input schema has 100% parameter description coverage, so schema already documents each field. The description adds no extra parameter details beyond listing actions, meeting the baseline but not exceeding it.

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?

Description clearly states the tool creates, removes, or reorders audio buses and routing, with specific actions listed. It uses a verb+resource structure, but does not explicitly differentiate from sibling tools like game_audio_bus or game_audio_effect.

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 or when-not-to-use guidance is provided. The description does not mention alternatives or prerequisites, leaving the agent to infer usage context from the action list 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?

Annotations are minimal (only title), so description carries full burden. It implies mutation ('add/remove/configure') but does not disclose side effects, permissions needed, or impact on existing audio. For a tool modifying audio bus effects, this is insufficient.

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?

The description is very short (four words) but this is under-specification rather than efficient conciseness. It lacks necessary elaboration expected for a 5-parameter tool with nested objects.

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 and moderate complexity (5 params, nested object), the description should explain expected behavior after applying effects, but it does not. The tool's purpose is stated but not fully contextualized.

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 descriptions are basic labels (e.g., 'Action: add, remove, configure, list'). The description adds no extra meaning beyond the schema; it does not clarify the 'properties' object structure or the role of 'index'. Baseline 3 is appropriate as schema does heavy lifting.

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 clearly states it handles adding, removing, and configuring audio bus effects, which distinguishes it from sibling tools like game_audio_bus (managing buses) and game_audio_play (playing audio). However, it does not explicitly differentiate from game_audio_spatial or other effect-related 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?

No guidance on when to use this tool versus alternatives, when to choose 'add' vs 'remove' vs 'configure', or prerequisites. The description is purely functional with no contextual advice.

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?

Description indicates mutability (play/stop/pause) but fails to disclose side effects, error states, or behavior for missing nodes. The action 'resume' is in the schema but not mentioned. No annotations compensate.

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?

Single sentence is concise but the tool handles 7 parameters and 4 actions; the brevity omits critical context, so it doesn't fully earn its place.

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 7 parameters and no output schema, the description is too minimal. It doesn't cover use cases, ordering, or combinations of actions (e.g., loading stream while playing).

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% with descriptions for all 7 parameters, so baseline is 3. The description adds no extra meaning beyond restating the tool's function; it doesn't clarify parameter interactions or defaults.

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 'Play, stop, or pause an AudioStreamPlayer node' clearly states the action and resource, distinguishing it from sibling audio tools like game_audio_bus or game_audio_effect.

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, no prerequisites or when-not-to-use conditions. Among many audio-related siblings, this lack of context hinders correct 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?

Annotations are minimal (only title), so the description must disclose behavioral traits. It only says 'Configure' without stating that it modifies the node's spatial properties, whether changes are reversible, or what permissions are needed. No mention of side effects or the 'get_info' action's behavior. Lacks essential transparency for a mutation 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 short sentence with no fluff. However, it could be slightly more informative without losing conciseness. Still, it earns a high score for efficiency.

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 6 parameters, no output schema, and no annotations, the description is insufficient. It doesn't explain the 'action' parameter (configure vs. get_info) or what 'get_info' returns. The tool's full behavior is unclear, especially for a dual-purpose tool. More context is needed for 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 each parameter is already described in the schema (e.g., maxDb, action). The description adds that these are 'spatial properties', but this is somewhat inferred from the tool name. Baseline 3 is appropriate as the description provides only marginal extra meaning beyond 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?

The description clearly states 'Configure AudioStreamPlayer3D spatial properties', specifying the verb and the exact resource. It distinguishes from sibling tools like game_audio_play (playing audio) and game_audio_bus (bus layout) by focusing on spatial properties of a specific node type.

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 like game_audio_play or game_audio_bus. It doesn't mention prerequisites (e.g., node must exist) or situations where 'get_info' vs 'configure' is appropriate. The description is purely declarative without usage context.

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 provide behavioral hints, so the description must fully disclose behavior. It mentions timeout and return args but does not explain timeout behavior (e.g., error or fallback), blocking nature, or what the returned arguments contain. This is insufficient for a likely blocking operation.

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?

The description is extremely concise (one short phrase) with no wasted words. It accomplishes its purpose efficiently, though it could benefit from slightly more detail without sacrificing conciseness.

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?

Given the complexity of awaiting a signal with timeout, the description is minimal. No output schema exists, so return value semantics are unclear. More details on timeout handling and return format are needed for full 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 has 100% coverage with descriptions for all 3 parameters. The description adds minimal extra meaning beyond 'timeout' and 'return args', which are already in the schema. Baseline 3 is 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?

The description clearly states the tool awaits a signal with a timeout and returns arguments. This verb+resource combination is specific and distinguishes it from siblings like connect/disconnect/emit/list signals.

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 explicit when-to-use or when-not-to guidance. The description implies use for awaiting a signal, but doesn't compare to alternatives like game_connect_signal or game_emit_signal, leaving the agent to infer context.

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 useful annotations (only title), the description must disclose behavioral traits. It states get/set but omits important details: what happens on set (permanent? immediate?), what if the bone doesn't exist, or what the return value looks like for get. The lack of output schema exacerbates this 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?

The description is a single sentence that is front-loaded with the action. It is concise, but could be slightly more informative without becoming verbose (e.g., mentioning the action parameter).

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?

Given 7 parameters, nested objects, and no output schema, the description is too minimal. It does not explain the default action, how to use parameters together, return format, or error scenarios. The agent lacks sufficient context to invoke the tool 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?

All 7 parameters have descriptions in the schema (100% coverage), so the baseline is 3. The description adds no extra meaning beyond the schema. It does not explain how parameters interact (e.g., boneName vs boneIndex, or that position/rotation/scale are used only with action='set').

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 clearly states the verb ('Get or set') and the resource ('bone poses on a Skeleton3D node'), providing a specific purpose. However, it does not distinguish from sibling tools like game_skeleton_ik or game_animation_control, which could cause confusion for an AI agent.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, common use cases, or scenarios where other tools (e.g., game_skeleton_ik) would be more appropriate. This leaves the agent without decision criteria.

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 (e.g., readOnlyHint, destructiveHint), and the description does not disclose behavioral traits such as potential side effects (calling a method may modify game state), error handling, or permission requirements. The agent has no insight into the tool's safety or impact.

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?

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?

Given the complexity of calling arbitrary methods on game nodes, the description is too brief. There are no annotations, no output schema, and no mention of return values, error conditions, or call limitations. The agent lacks essential context to use the tool safely and effectively.

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%, and the input schema already documents all three parameters with clear descriptions. The description adds no extra meaning beyond 'with optional arguments', which matches the schema's description for 'args'. Therefore, the description does not enhance the schema's information.

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 specifies that the tool calls a method on any node with optional arguments. It clearly identifies the verb ('call'), resource ('method on any node'), and scope ('in the running game'). While it does not explicitly differentiate from siblings like game_eval or game_set_property, the action is distinct enough among the list of sibling 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?

No guidance is provided on when to use this tool versus alternatives, such as game_eval for evaluating expressions or game_set_property for setting properties. The description also lacks any indication of when not to use it, leaving the agent without context for appropriate invocation.

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

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?

The description is a single 10-word sentence that efficiently communicates the core purpose. It is concise and front-loaded, though no structured list or additional organization is needed 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?

With 7 parameters, no output schema, and minimal annotations, the description should provide more context. It does not explain what DOF or exposure terms mean, typical values, or what the result of configure is. Incomplete relative to tool complexity.

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% for 7 parameters, so the description adds minimal value beyond grouping them as DOF, exposure, auto-exposure. Baseline of 3 is appropriate since schema already documents each parameter.

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?

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?

The description is a single, concise sentence. It is not verbose, but it is very brief, leaving out potentially helpful guidance. Still, it earns a high score for conciseness.

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?

Given the tool has 5 optional parameters and no output schema or annotations, the description is overly minimal. It fails to explain the Timer node's role in gameplay, impact on performance, or common use cases for parameters like 'oneShot' and 'autostart'. The sibling list is extensive, but no comparisons are drawn.

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 baseline is 3. The description adds no parameter-specific meaning beyond 'with configuration', effectively providing no additional value over 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?

The description clearly states the action ('Create') and resource ('Timer node'), and the input schema confirms configuration options. While it does not explicitly differentiate from sibling tools like 'add_node' or 'game_spawn_node', there is no direct sibling for timer creation, so this is adequate.

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 is provided on when to use this tool versus alternatives such as 'add_node' or 'game_animation_control'. The description lacks context about prerequisites, typical scenarios, or when not to use it.

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?

Annotations only include a title, with no readOnlyHint or destructiveHint. Description implies mutation but does not disclose additional behavioral traits such as side effects, permissions, or error conditions.

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

Annotations are minimal (only title), so description carries full burden. It only says 'Draw debug lines, spheres, or boxes in 3D' without disclosing that draws accumulate, require manual clearing, or have performance implications. The 'duration' parameter's behavior is not explained beyond schema.

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?

Extremely concise single sentence. Could be slightly improved by hinting at parameter dependencies (e.g., shape-specific parameters).

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 8 parameters, nested objects, and no output schema, the description is insufficient. It fails to explain shape selection, coordinate system, or how multiple draws interact.

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 description clearly states the action ('Get'), the resource ('property value from any node'), and the means ('by its path'). It distinguishes from sibling tools like 'game_set_property' which sets properties, and 'game_get_node_info' which returns more comprehensive node data.

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 description provides no guidance on when to use this tool versus alternatives. With over 100 sibling tools, it should at least differentiate from 'game_set_property' and 'game_get_node_info', but it does not offer any context or exclusions.

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?

Annotations provide no hints (no readOnlyHint or destructiveHint). The description adds no behavioral details beyond the name itself—e.g., it does not state that this is a read-only operation, that it returns the full tree or a subset, or whether it works only on running games. This lack of disclosure leaves the agent uninformed about invocation consequences.

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?

The description is a single, clear sentence with no wasted words. It is front-loaded and efficient. However, it could be slightly expanded to include output details without becoming verbose, so it is concise but not maximally informative.

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?

Given the tool complexity (no parameters, no output schema), the description is minimally viable. It conveys the basic purpose but omits details about the structure of the returned scene tree (e.g., node hierarchy, properties). An agent would need additional context to fully utilize the output.

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 input schema has zero parameters, and schema description coverage is trivially 100%. With no parameters to describe, the baseline score is 4. The description provides no additional parameter information, which is acceptable given the absence of 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?

The description clearly states the tool gets the scene tree structure of the running game, using a specific verb ('Get') and resource ('scene tree structure'). However, it does not differentiate from sibling tools like 'godot_scene_tree' or 'manage_scene_structure', which may have overlapping functionality.

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 usage context is provided. The description does not specify when to use this tool versus alternatives, nor does it mention any prerequisites or side effects. The agent receives no guidance on optimal invocation scenarios.

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?

Annotations provide no behavioral hints (no readOnlyHint or destructiveHint). The description states 'Get' implying a read operation, but does not disclose potential side effects, authentication needs, or how the UI elements are returned (e.g., structure, enumeration).

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?

Single sentence of eight words with no redundant information. Every word is essential for 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 a simple tool with no parameters and no output schema, the description gives a basic understanding. However, it lacks information about the return format (e.g., list of element identifiers or paths), which would help the agent process results. Adequate but not comprehensive.

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?

No parameters exist; schema coverage is 100% (empty). The description does not need to add parameter details. It does not contradict the schema, so it meets the baseline for zero-parameter tools.

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 clearly states it gets visible UI elements, distinguishing it from sibling tools that manipulate UI (e.g., game_ui_control, game_ui_item_list). However, it could be more specific about what constitutes 'visible UI elements'.

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 like game_ui_control for manipulation. The phrase 'from the running game' implies context but does not exclude other tools explicitly.

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 provide destructive or read-only hints. The description implies mutability but does not disclose side effects (e.g., whether it overwrites existing nodes), required permissions, or what 'configure' entails beyond creation.

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?

Single sentence, no wasted words. While it could include more context, it is appropriately concise for a tool that is one of many.

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?

No output schema, and description lacks detail on return values or behavioral expectations. GI is a complex concept; minimal description does not sufficiently guide an AI agent on usage and outcomes.

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 schema already describes parameters. The description adds no extra meaning beyond mapping 'voxel_gi'/'lightmap_gi' to giType. Baseline 3 applies.

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?

Description clearly states the tool creates/configures two specific GI types (VoxelGI or LightmapGI), using a specific verb and resource. It distinguishes from sibling tools like game_light_3d or game_environment.

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 vs alternatives such as game_environment or game_light_3d. Does not mention prerequisites or typical scenarios.

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 (readOnlyHint, destructiveHint), the description must disclose behavioral traits. It only lists actions without explaining side effects, permissions, or whether changes are immediate. For a mutation tool, this is insufficient.

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?

The description is a single, efficient sentence that gets the core idea across quickly. However, it could be slightly more informative without losing conciseness.

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?

Given the tool's complexity (7 parameters, multiple actions) and absence of an output schema, the description is too sparse. It does not explain return values for queries or the effect of actions, leaving important 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 100%, so the description adds minimal value beyond the schema's parameter descriptions. It does not clarify parameter dependencies or action-specific requirements, earning a baseline 3.

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 clearly lists specific actions (set, get, clear, query) and the resource (GridMap cells), making the tool's purpose unambiguous. It distinguishes itself from sibling tools by focusing on grid cell operations.

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 is provided on when to use this tool versus alternatives or when not to use it. The description does not mention prerequisites or context, leaving the agent without decision support.

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 only a title in annotations, the description should disclose behavioral traits like error handling, redirects, authentication, or side effects. It only lists methods and components, omitting critical behavioral context.

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?

The description is a single sentence that directly conveys the core functionality. It is front-loaded and contains no unnecessary 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?

Despite having 5 parameters, no output schema, and minimal annotations, the description fails to explain return values, error states, or usage context. It is too brief for the tool's complexity.

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 baseline is 3. The description adds no parameter-specific meaning beyond the schema's field descriptions, which are already adequate.

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

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 vs alternatives. The description does not mention prerequisites, common use cases, or when not to use it, leaving the agent without contextual decision support.

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 beyond the title, the description carries full responsibility for behavioral disclosure. It only says 'Manage', but does not reveal that actions like 'remove_action' are destructive, nor does it mention runtime implications or required permissions.

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?

The description is a single sentence that is clear and front-loaded. It is concise but may be too brief to fully inform the agent.

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

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 clearly states it manages runtime InputMap actions and strength, using a specific verb and resource. However, it does not differentiate from the sibling tool 'manage_input_map', which likely has overlapping functionality.

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 is provided on when to use this tool versus alternatives like 'manage_input_map' or 'game_input_state'. The description lacks context for usage decisions.

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?

Despite no annotations, the description fails to disclose that the tool can mutate state (warp_mouse, set_mouse_mode). It presents only a read operation ('Query'), which is inaccurate and hides behavioral traits.

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?

The description is overly brief (5 words) and omits critical actions, making it incomplete rather than concise. It fails to earn its place by not covering the tool's full functionality.

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?

Given 4 parameters and no output schema, the description should at least mention the three actions (query, warp_mouse, set_mouse_mode) to set user expectations. Its incompleteness leaves the agent underinformed.

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 description adds no additional meaning beyond what is already documented in the schema. Baseline score of 3 is appropriate as no value is added.

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 states 'Query pressed keys, mouse position, connected pads' which identifies the querying purpose, but it omits the 'warp_mouse' and 'set_mouse_mode' actions defined in the schema, making the purpose incomplete and slightly misleading.

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 is provided on when to use this tool versus sibling input tools like game_key_hold, game_mouse_move, or game_input_action. The description lacks any context for selection or exclusions.

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?

Annotations provide no readOnlyHint or destructiveHint. Description states mutation (adding node to scene tree) but lacks details on permissions, reversibility, or error handling. Adequate but not thorough.

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?

Single sentence, no redundancy, front-loaded with key verb and resource. Efficient but could benefit from minor restructuring for readability.

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?

Tool has two simple parameters, no output schema. Description is minimal but lacks context about return value or side effects beyond adding node. Adequate for simple tool but could be more complete.

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% with clear descriptions for both parameters. The tool description adds no additional meaning beyond what the schema already provides.

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?

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 explicit guidance on when to use this tool versus alternatives like add_node or game_spawn_node. Usage is implied but not clarified with when-not or exclusion criteria.

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?

The description mentions 'without auto-releasing', which partially discloses behavior, but it fails to specify whether the hold is blocking, how to end the hold, or what happens on overlapping inputs. With no annotations (destructiveHint, readOnlyHint) to supplement, more clarity is needed.

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?

The description is a single, concise sentence that conveys the core functionality immediately. It avoids unnecessary detail and is front-loaded, making it efficient for an agent to parse.

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?

Given the low complexity (2 optional parameters, no output schema), the description covers the basic purpose but lacks details on side effects, return values, or how the hold interacts with the game environment. It is adequate but not comprehensive.
