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 implies a mutation ('Associate') but doesn't specify permissions required, whether the association is reversible, error conditions, or side effects. This is inadequate for a tool that modifies data without structured safety hints.

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 with zero waste. It is front-loaded with the core action and purpose, making it easy to parse quickly without unnecessary elaboration.

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 as a mutation with no annotations and no output schema, the description is incomplete. It lacks details on behavioral traits, error handling, or return values, which are critical for safe and effective use in an automated context.

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 both parameters ('id' and 'cid') fully. The description adds no additional meaning beyond what the schema provides, such as format examples or constraints, resulting in a baseline score of 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 states the action ('Associate') and the resources involved ('a CID with a payment instruction'), specifying the purpose for 'x402 monetization'. It distinguishes from sibling tools like 'removeCidFromPaymentInstruction' by indicating an addition rather than removal, though it doesn't explicitly compare to other CID-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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing payment instruction), exclusions, or comparisons to sibling tools like 'listPaymentInstructionCids' or 'createPaymentInstruction', leaving usage context unclear.

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 provided, the description carries full burden but only states the basic operation without disclosing behavioral traits. It doesn't mention permissions needed, whether this is idempotent, rate limits, error conditions, or what happens if the file is already in the group. This leaves significant gaps 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?

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 fully documents all parameters (network, groupId, fileId). The description adds no additional meaning beyond implying 'existing file' and 'group', which is already covered by parameter descriptions. Baseline 3 is appropriate when schema does the 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 the action ('Add') and resources ('existing file', 'group in your Pinata account'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'removeFileFromGroup' or 'createGroup', which would require mentioning this is for existing files/groups rather than creation or removal 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?

The description provides no guidance on when to use this tool versus alternatives like 'removeFileFromGroup' or 'createGroup'. It mentions 'existing file' and 'group' but doesn't clarify prerequisites (e.g., both must already exist) or exclusions (e.g., not for creating new groups).

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 mentions 'content verification' but doesn't disclose behavioral traits like whether this is a read-only or mutating operation, what happens on success/failure, if it requires authentication, or any rate limits. The description is too minimal for a tool that likely involves cryptographic operations.

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 with zero waste. It is front-loaded with the core purpose and avoids unnecessary details, making it highly concise and well-structured for quick understanding.

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 cryptographic signing and no annotations or output schema, the description is incomplete. It doesn't explain what the tool returns, error conditions, or security implications. For a tool with 4 parameters and no structured behavioral hints, more context is needed to guide proper usage.

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 fully documents all parameters. The description adds no additional meaning beyond implying the signature is for verification, which is already suggested by 'EIP-712 cryptographic signature'. Baseline score of 3 is appropriate as the schema handles parameter documentation.

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 ('Add an EIP-712 cryptographic signature') and the resource ('to a CID'), making the purpose specific and understandable. It distinguishes from siblings like 'deleteSignature' by focusing on addition rather than removal, though it doesn't explicitly contrast with all 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?

The description provides no guidance on when to use this tool versus alternatives like 'getSignature' or 'deleteSignature', nor does it mention prerequisites such as needing a valid signature or address. It lacks context about typical use cases or constraints.

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 provided, the description carries full burden for behavioral disclosure. It states the action is 'Cancel' (implying mutation/reversal), but doesn't address permissions needed, whether cancellation is reversible, error conditions, or what happens upon success. This leaves significant behavioral gaps 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 a single, efficient sentence with zero wasted words. It's front-loaded with the core action and target, making it immediately scannable and appropriately sized for the tool's apparent complexity.

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 mutation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what 'cancel' entails operationally, what the expected outcome is, or any side effects. Given the context of managing pin requests, more completeness is needed to guide effective use.

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% (the 'id' parameter is fully described in the schema), so the baseline is 3. The description doesn't add any parameter-specific details beyond what the schema already provides about the 'id' being for the pin request to cancel.

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 ('Cancel') and target resource ('a pending pin by CID request'), making the purpose immediately understandable.

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

The input schema has 100% description coverage, with the 'id' parameter clearly documented as 'The unique identifier of the payment instruction to delete'. The description does not add extra meaning beyond this, but with high schema coverage and only one parameter, a baseline of 4 is appropriate as the schema adequately handles the semantics.

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 ('Delete') and resource ('an x402 payment instruction'), making the purpose unambiguous. However, it does not differentiate this tool from sibling tools like 'deleteFile' or 'deleteGroup', which have similar deletion patterns but target different resources.

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, such as 'cancelPinRequest' or 'updatePaymentInstruction', nor does it mention prerequisites like needing the payment instruction ID or conditions for deletion. It lacks explicit when/when-not instructions or sibling comparisons.

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 provided, the description carries full burden for behavioral disclosure. It states the action is 'Remove,' implying a destructive mutation, but doesn't specify permissions required, whether the operation is reversible, error conditions, or what happens to the CID after signature removal. This leaves significant behavioral gaps 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 a single, direct sentence with no wasted words, making it highly concise and front-loaded. Every word contributes to stating the tool's purpose efficiently.

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 this is a mutation tool with no annotations and no output schema, the description is incomplete. It lacks details on behavioral aspects like side effects, return values, or error handling, which are crucial for safe and effective use. The high schema coverage doesn't compensate for these gaps in context.

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 fully documents both parameters. The description doesn't add any meaning beyond what's in the schema (e.g., it doesn't explain what a 'signature' is in this context or how removal affects the CID). Baseline 3 is appropriate when the schema handles parameter documentation.

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 ('Remove') and target ('signature from a CID'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'deleteFile' or 'deleteFileVectors', which also perform deletion operations on related resources, so it doesn't achieve full sibling distinction.

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 like 'deleteFile' or 'getSignature', nor does it mention prerequisites or exclusions. It's a basic statement of function without contextual usage information.

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 provided, the description carries the full burden of behavioral disclosure. It states the tool fetches and returns content, implying a read-only operation, but lacks details on authentication requirements (especially for private IPFS), rate limits, error handling, or what 'return it' entails (e.g., format, size limits). For a tool with potential network and access complexities, this is a significant gap in transparency.

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 front-loads the core action ('fetch content') and key details (source, gateway). There is no wasted verbiage or redundancy, making it highly concise and well-structured for quick comprehension.

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 IPFS operations and lack of annotations or output schema, the description is incomplete. It doesn't address authentication needs for private networks, error cases (e.g., invalid CID), return formats, or performance considerations. For a tool that interacts with external gateways and handles both public and private data, more contextual information is needed to ensure reliable use.

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%, with clear documentation for both parameters (cid and network). The description adds minimal value beyond the schema, mentioning 'Public or Private IPFS' which aligns with the network enum but doesn't elaborate on implications. With high schema coverage, the baseline score of 3 is appropriate as the description doesn't significantly enhance parameter understanding.

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 ('fetch content') and target ('from Public or Private IPFS via Pinata gateway'), with the specific resource being content identified by CID. It distinguishes from siblings like 'getFileById' or 'uploadFile' by focusing on gateway retrieval rather than direct file operations. However, it doesn't explicitly differentiate from similar tools like 'createPrivateDownloadLink' which might also involve content access.

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. It doesn't mention prerequisites (e.g., authentication needs for private IPFS), compare with siblings like 'getFileById' or 'createPrivateDownloadLink', or specify scenarios where gateway fetching is preferred over direct methods. Usage is implied by the action but without explicit 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 annotations provided, the description carries full burden for behavioral disclosure. It states this is a retrieval operation but doesn't mention authentication requirements, rate limits, error behavior, or what 'detailed information' includes. For a read operation in a system with authentication tools like 'testAuthentication', 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 immediately conveys the core purpose without any wasted words. It's appropriately sized for a simple retrieval tool and front-loads the essential information.

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 no annotations and no output schema, the description is inadequate. It doesn't explain what 'detailed information' includes, authentication requirements, or error handling. Given the sibling tools include authentication and various file operations, more context is needed for proper agent usage.

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 both parameters thoroughly. The description adds no additional parameter context beyond what's in the schema descriptions. The baseline of 3 is appropriate when the schema does all 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?

The description clearly states the action ('Retrieve detailed information') and resource ('specific file stored on Pinata by its ID'), making the purpose immediately understandable. It doesn't explicitly differentiate from siblings like 'searchFiles' or 'fetchFromGateway', but the specificity of 'by its ID' provides some implicit distinction.

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 like 'searchFiles' or 'fetchFromGateway'. It doesn't mention prerequisites, error conditions, or typical use cases, leaving the agent to infer usage from the tool name and parameters alone.

It doesn't specify what information is returned (e.g., group attributes, status), how errors are handled, or dependencies, leaving the agent with insufficient context for reliable use.

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 fully documents both parameters ('network' with enum/default and 'id' as required). The description adds no additional parameter semantics beyond implying 'id' is needed for retrieval, which is already clear from the schema. This meets the baseline for high schema coverage.

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 ('Retrieve detailed information') and resource ('about a specific group by its ID'), making the purpose unambiguous. However, it doesn't differentiate from sibling tools like 'listGroups' or 'getFileById', which would require mentioning this is for individual group details rather than listing or file retrieval.

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?

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 states the tool pins an existing CID, implying a write/mutation operation, but doesn't disclose behavioral traits like required permissions, rate limits, whether the pin is permanent or reversible, or what happens on failure. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 front-loads the core purpose ('Pin an existing CID from the IPFS network to your Pinata account'). There's no wasted text, repetition, or unnecessary elaboration, making it highly concise and well-structured for quick understanding.

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 parameters, no annotations, and no output schema, the description is minimally adequate. It states the purpose clearly but lacks behavioral context (e.g., mutation effects, error handling) and doesn't explain return values. For a mutation tool with this complexity, it should do more to compensate for the missing structured data, but it meets the bare minimum for understanding what the tool does.

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 5 parameters (cid, name, group_id, keyvalues, host_nodes). The description doesn't add any parameter-specific semantics beyond what's in the schema, such as format examples or usage tips. With high schema coverage, the baseline is 3, as the description doesn't compensate but also doesn't detract.

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 ('Pin') and resource ('an existing CID from the IPFS network to your Pinata account'), distinguishing it from sibling tools like 'uploadFile' (which creates new content) and 'addFileToGroup' (which manages group membership). It specifies that the CID must already exist in the IPFS network, which is a key differentiator.

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 implies usage by stating 'Pin an existing CID from the IPFS network', suggesting it's for content already available on IPFS. However, it doesn't explicitly state when to use alternatives like 'uploadFile' (for new content) or 'addFileToGroup' (for grouping), nor does it mention prerequisites or exclusions, leaving some ambiguity for the agent.

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 provided, the description carries full burden for behavioral disclosure but offers minimal information. It states the tool queries status, implying a read-only operation, but doesn't clarify if it requires authentication, has rate limits, returns paginated results (though 'pageToken' in schema hints at this), or what happens on errors. For a query tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 with zero waste—it directly states the tool's purpose without redundancy. It's appropriately sized for a query tool and front-loaded with essential information, making it easy to parse quickly.

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 (5 parameters, no annotations, no output schema), the description is incomplete. It doesn't explain the return format (e.g., list of requests with fields), error handling, or authentication needs. While the schema covers parameters well, the lack of behavioral context and output details leaves the agent with insufficient information for reliable use.

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 schema description coverage is 100%, with clear descriptions for all parameters (e.g., 'order' sorts by date_queued, 'status' filters by status). The description adds no additional parameter semantics beyond what the schema provides, such as explaining 'cid' filtering specifics or 'limit' defaults. Baseline score of 3 is appropriate as the schema adequately documents 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 action ('Query') and resource ('status of pin by CID requests'), making the purpose understandable. It distinguishes itself from siblings like 'pinByCid' or 'cancelPinRequest' by focusing on querying status rather than creating or modifying requests. However, it lacks specificity about what 'status' entails (e.g., pending, completed) beyond the enum values in the schema.

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. It doesn't mention prerequisites (e.g., needing existing pin requests), exclusions, or comparisons to sibling tools like 'listPaymentInstructionCids' or 'searchFiles' that might overlap in querying data. Usage is implied only through the tool name and description 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 annotations, the description carries full burden but provides minimal behavioral insight. It mentions semantic search but doesn't disclose performance characteristics, result format, pagination, authentication needs, or error conditions. For a query tool with no annotations, this leaves significant gaps in understanding how it behaves.

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 with zero waste - every word contributes essential information. Front-loaded with the core purpose, appropriately sized for a simple query 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?

For a query tool with no annotations and no output schema, the description is insufficient. It doesn't explain what 'vectorized files' means, what the search returns, or how results are structured. Given the complexity implied by 'semantic search' and lack of structured output documentation, more context is needed.

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 fully documents both parameters. The description adds no additional parameter semantics beyond what's in the schema (group_id for group selection, text for query). Baseline 3 is appropriate when schema does all 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?

The description clearly states the action ('query') and resource ('vectorized files in a group') with the method ('semantic search'). It distinguishes from obvious siblings like 'searchFiles' by specifying vectorized content and semantic search, though it doesn't explicitly contrast with all siblings.

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 'searchFiles' or 'getFileById' is provided. The description implies usage for semantic search on vectorized files, but lacks explicit when/when-not instructions or prerequisite context about needing vectorized files first.

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 provided, the description carries full burden but only states the action without disclosing behavioral traits like whether this is a destructive operation, permission requirements, side effects, or error conditions. It lacks context on what 'remove' entails beyond the basic meaning.

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 zero wasted words, making it highly concise and front-loaded. It efficiently communicates the core purpose without unnecessary elaboration.

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 (a mutation operation with no annotations and no output schema), the description is insufficient. It doesn't cover what happens after removal, potential errors, or confirmation of success, leaving significant gaps for an AI agent to understand the tool's full 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 the schema fully documents both parameters ('id' and 'cid'). The description adds no additional meaning beyond implying these parameters are used for the removal, which aligns with the schema but doesn't enhance understanding. Baseline 3 is appropriate here.

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 ('Remove') and target ('a CID association from a payment instruction'), which is specific and unambiguous. However, it doesn't explicitly differentiate from its sibling 'removeFileFromGroup' or other removal operations, keeping it from a perfect score.

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 'deletePaymentInstruction' or 'updatePaymentInstruction', nor does it mention prerequisites such as needing an existing CID association. The description only states what it does, not when or why 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?

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It implies a mutation ('Remove') but doesn't disclose permissions required, whether the operation is reversible, rate limits, or what happens to the file/group post-removal (e.g., if the file persists elsewhere). This leaves significant gaps for a tool that likely alters data.

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 directly states the tool's purpose without unnecessary words. It's front-loaded with the core action and context, making it easy to parse quickly.

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 mutation tool with no annotations and no output schema, the description is inadequate. It doesn't explain the outcome (e.g., success response, error cases), side effects, or dependencies, leaving the agent with insufficient context to use it 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%, providing clear documentation for all parameters (network, groupId, fileId). The description adds no additional parameter semantics beyond what's in the schema, such as format examples or interdependencies. Baseline 3 is appropriate since the schema handles the 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 the action ('Remove') and the target ('a file from a group'), specifying the context ('in your Pinata account'). It distinguishes from obvious siblings like 'addFileToGroup' and 'deleteFile', but doesn't explicitly differentiate from all related tools like 'deleteGroup' or 'updateGroup'.

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. It doesn't mention prerequisites (e.g., needing an existing group and file), exclusions, or comparisons with tools like 'deleteFile' (which might delete entirely) or 'updateGroup' (which might modify membership differently).

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 provided, the description carries the full burden of behavioral disclosure. It mentions the tool returns a list of files but doesn't describe pagination behavior (implied by 'pageToken' parameter), rate limits, authentication requirements, or error conditions. For a search tool with 6 parameters, this leaves significant gaps in understanding how it behaves.

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 efficiently structured in two clear sentences: one stating the search functionality and criteria, another stating the return value. Every word contributes meaning with zero waste 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?

Given the tool's moderate complexity (6 parameters, search functionality) and lack of both annotations and output schema, the description is minimally adequate. It covers the basic purpose but lacks details about behavioral traits, usage context, and return format that would be helpful for an AI agent.

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 parameters thoroughly. The description adds minimal value by mentioning three filter criteria (name, CID, MIME type) but doesn't provide additional context beyond what's in the schema. This meets the baseline for high schema coverage.

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 searches for files by specific criteria (name, CID, or MIME type) and returns matching files, providing a specific verb ('search') and resource ('files in your Pinata account'). However, it doesn't explicitly differentiate from sibling tools like 'getFileById' or 'listGroups', which reduces it from a perfect score.

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 mentions what the tool does but provides no guidance on when to use it versus alternatives like 'getFileById' (for specific files) or 'listGroups' (for broader listings). There's no mention of prerequisites, performance considerations, or typical use cases.

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 states the tool verifies JWT validity, implying a read-only, non-destructive operation, but doesn't disclose behavioral traits like error handling, rate limits, or response format. For a tool with zero annotation coverage, this is a significant gap in transparency.

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: 'Verify that your Pinata JWT is valid and working.' It's front-loaded with the core purpose, has no wasted words, and is appropriately sized 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's simplicity (0 parameters, no output schema, no annotations), the description is minimal. It states the purpose but lacks context on usage, behavioral details, or output expectations. For a tool in a server with many authentication-related siblings, more completeness is needed to guide the agent 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?

The input schema has 0 parameters with 100% coverage, so no parameters need documentation. The description doesn't add parameter details, which is acceptable here. Baseline is 4 for zero parameters, as there's nothing to compensate for.

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's purpose: 'Verify that your Pinata JWT is valid and working.' It specifies the action (verify) and the resource (Pinata JWT), making it easy to understand. However, it doesn't explicitly differentiate from sibling tools, which include various authentication-related tools like 'createSignedUploadUrl' or 'addSignature,' so it misses the top score.

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. It doesn't mention prerequisites, such as needing a JWT to test, or compare it to other tools like 'createSignedUploadUrl' for authentication setup. This leaves the agent without context 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 full burden. It states this updates metadata, implying a mutation, but lacks critical behavioral details: whether authentication is required, if changes are reversible, rate limits, error conditions, or what happens to existing metadata not mentioned. The description is minimal and doesn't compensate for the absence of annotations.

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 front-loads the core purpose. It avoids redundancy and wastes no words, though it could be slightly more structured (e.g., separating scope from parameters). Every part earns its place, making it appropriately concise.

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 no annotations, no output schema, and a mutation tool with 4 parameters, the description is incomplete. It lacks behavioral context (e.g., permissions, side effects), output details, and usage guidelines. While the schema covers parameters well, the description doesn't add enough value to compensate for missing structured data, leaving gaps for an AI agent.

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 fully documents all 4 parameters. The description mentions 'name and key-value pairs', aligning with the 'name' and 'keyvalues' parameters, but adds no additional meaning beyond what the schema provides (e.g., format examples, constraints). With high schema coverage, the baseline score of 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 action ('Update metadata'), target resource ('existing file on Pinata'), and specific fields ('name and key-value pairs'). It distinguishes from siblings like 'uploadFile' (creation) and 'deleteFile' (removal), though it doesn't explicitly contrast with 'updateGroup' or 'updatePaymentInstruction' which update different resources.

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.
