Tool Scores

• complete_taskC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool 'toggles' completion status, which implies a mutation operation, but doesn't specify whether this requires permissions, is reversible, has side effects, or what the response looks like. The description lacks details on rate limits, error conditions, or how the toggle interacts with the 'status' parameter, leaving behavioral traits unclear.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's front-loaded with the core action and resource, making it easy to parse. Every part of the sentence earns its place by conveying essential information concisely.

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

  Completeness2/5

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

  Given the tool's complexity (a mutation operation with 2 parameters), lack of annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects like permissions, reversibility, or response format, nor does it provide usage context relative to siblings. For a mutation tool with no structured safety or output information, the description should do more to compensate.

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

  Parameters3/5

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

  Schema description coverage is 100%, with clear descriptions for both parameters ('taskId' and 'status'). The description adds no additional meaning beyond what the schema provides—it doesn't explain parameter interactions, constraints, or usage examples. Since the schema does the heavy lifting, the baseline score of 3 is appropriate, as the description neither compensates for gaps nor adds value.

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

  Purpose4/5

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

  The description clearly states the action ('toggle') and resource ('completion status of a task'), making the purpose immediately understandable. It doesn't explicitly distinguish from siblings like 'create_task' or 'delete_task', but the verb 'toggle' implies a different operation than creation or deletion. The description avoids tautology by not just restating the name 'complete_task'.

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

  Usage Guidelines2/5

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

  The description provides no guidance on when to use this tool versus alternatives like 'create_task' or 'delete_task'. It doesn't mention prerequisites (e.g., needing an existing task), exclusions, or contextual factors. While the action 'toggle' implies it modifies existing tasks, this is only implied rather than explicitly stated as usage guidance.

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

• delete_taskC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a deletion operation, implying it's destructive, but doesn't clarify if deletions are permanent/reversible, what permissions are required, or what happens on success/failure. For a mutation tool with zero annotation coverage, 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.

  Conciseness5/5

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

  The description is a single, efficient sentence that front-loads the core action ('Delete a task') without any wasted words. It's appropriately sized for a simple tool with one parameter.

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

  Completeness2/5

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

  Given this is a destructive mutation tool with no annotations and no output schema, the description is incomplete. It doesn't address critical context like what 'delete' entails (permanent removal?), error conditions, or return values, leaving significant gaps for agent understanding.

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

  Parameters3/5

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

  The input schema has 100% description coverage, with the single parameter 'taskId' clearly documented. The description adds no additional parameter semantics beyond implying deletion targets a specific task ID, so it meets the baseline of 3 where the schema does the heavy lifting.

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

  Purpose4/5

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

  The description clearly states the verb ('Delete') and resource ('a task from the default task list'), making the purpose immediately understandable. However, it doesn't explicitly distinguish this from sibling tools like 'complete_task' which might also remove tasks from view, though deletion is more permanent.

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

  Usage Guidelines2/5

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

  The description provides no guidance on when to use this tool versus alternatives like 'complete_task' or 'list_tasks'. It doesn't mention prerequisites (e.g., needing an existing task ID) or warn against misuse, leaving the agent to infer usage from context alone.

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

• create_taskB
  3.1/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden for behavioral disclosure. While 'Create' implies a write/mutation operation, the description doesn't address permission requirements, whether the operation is idempotent, what happens on failure, or any rate limits. It provides minimal behavioral context beyond the basic action.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that states the core purpose without any wasted words. It's appropriately sized for a simple creation tool and gets straight to the point.

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

  Completeness3/5

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

  For a creation tool with no annotations and no output schema, the description provides basic purpose but lacks important context about behavioral traits, error handling, and relationship to sibling tools. It's minimally adequate but has clear gaps in completeness given the mutation nature of the operation.

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

  Parameters3/5

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

  Schema description coverage is 100%, with both parameters ('title' and 'notes') fully documented in the schema. The description adds no additional parameter information beyond what the schema already provides, so the baseline score of 3 is appropriate when the schema does the heavy lifting.

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

  Purpose4/5

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

  The description clearly states the action ('Create a new task') and the target resource ('in Google Tasks'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'complete_task' or 'delete_task' beyond the obvious action difference.

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

  Usage Guidelines2/5

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

  No guidance is provided about when to use this tool versus alternatives. The description doesn't mention prerequisites, when not to use it, or how it relates to sibling tools like 'list_tasks' for viewing existing tasks before creating new ones.

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

• list_tasksB
  3.2/5.0
  Behavior2/5

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

  No annotations are provided, so the description carries full burden for behavioral disclosure. It states this lists 'all tasks' but doesn't clarify what 'all' means (e.g., completed vs. pending, pagination limits, or sorting). For a read operation with zero annotation coverage, this leaves significant gaps in understanding the tool's behavior.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that communicates the core purpose without any wasted words. It's front-loaded with the essential information and appropriately sized for a simple tool with no parameters.

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

  Completeness3/5

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

  Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is minimally adequate. However, for a listing operation, it should ideally mention what 'all tasks' includes (e.g., status filters, limits) or the return format, especially since there's no output schema to clarify this.

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

  Parameters4/5

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

  The input schema has 0 parameters with 100% coverage, so there's no parameter documentation burden. The description appropriately doesn't waste space discussing nonexistent parameters, earning a baseline score of 4 for not adding unnecessary information.

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

  Purpose4/5

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

  The description clearly states the action ('List') and resource ('tasks in the default task list'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling tools like 'complete_task' or 'create_task', but the verb 'List' inherently distinguishes it from mutation operations.

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

  Usage Guidelines2/5

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

  The description provides no guidance on when to use this tool versus alternatives. While it's obvious this is for listing tasks rather than creating or deleting them, it doesn't mention whether this should be used for initial discovery, how it relates to filtering or searching capabilities, or any prerequisites for accessing the default task list.

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