TDQS

C2.7/5.0
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 action ('add liquidity') but lacks details on permissions required, whether it's a mutating operation (implied by 'add'), potential costs, rate limits, or what happens upon success/failure. For a financial 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.

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 appropriately sized and front-loaded, with zero waste.

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 complexity of a financial liquidity operation, no annotations, and no output schema, the description is incomplete. It doesn't explain what 'liquidity' entails in this context, what the tool returns, or any side effects. The schema covers parameters well, but overall context for safe and effective use is lacking.

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 clear parameter descriptions (e.g., 'Amount of SOL to add to liquidity pool'). The tool description adds no additional meaning beyond what the schema provides, such as explaining parameter relationships or constraints. Baseline 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.

Purpose3/5

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

The description states the action ('add liquidity') and target ('created token'), which provides a basic purpose. However, it's vague about what 'created token' refers to (presumably a token created via the sibling 'create_token' tool) and doesn't distinguish this from other liquidity-related tools (none exist in siblings, but clarity is still limited). It avoids tautology by specifying the action beyond just the name.

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 on when to use this tool versus alternatives. The description doesn't mention prerequisites (e.g., needing a created token first, possibly via 'create_token'), exclusions, or contextual triggers. It's a standalone statement with no usage context.

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

calculate_amountsC

Calculate token amounts for each employee

ParametersJSON Schema
NameRequiredDescriptionDefault
roleAmountsNoToken amounts by role (if CSV with roles is used)
uniformAmountNoUniform amount for all employees (if no CSV role-mapping is used)

TDQS

C2.9/5.0
Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure but only states the calculation purpose. It doesn't reveal whether this is a read-only operation, if it requires specific permissions, what the output format is, or any rate limits or side effects, leaving significant gaps.

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 any fluff or redundancy. It's appropriately sized and front-loaded, making it easy to understand quickly.

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 complexity (2 parameters with nested objects) and lack of annotations or output schema, the description is insufficient. It doesn't explain the calculation logic, output format, or how parameters interact, leaving the agent with incomplete context for proper tool invocation.

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%, so the schema already documents both parameters thoroughly. The description adds no additional meaning beyond what the schema provides, such as explaining the relationship between 'roleAmounts' and 'uniformAmount' or usage scenarios, meeting the baseline for high coverage.

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 ('calculate') and target ('token amounts for each employee'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'calculate_fees' or 'start_airdrop' which might involve similar calculations, 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.

Usage Guidelines2/5

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

The description offers no guidance on when to use this tool versus alternatives like 'calculate_fees' or 'start_airdrop', nor does it mention prerequisites or context. It merely states what it does without indicating appropriate scenarios.

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

calculate_feesB

Calculate gas fees for the airdrop

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.2/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states it 'calculates' gas fees, implying a read-only operation, but doesn't specify if it requires authentication, network state, or returns estimated vs. actual fees. For a 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.

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 is appropriately sized and front-loaded, with every part earning its place.

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 has 0 parameters, no annotations, and no output schema, the description is minimally adequate. It explains what the tool does but lacks details on usage context, behavioral traits, or output format, which could be important for an airdrop-related calculation tool.

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 no parameter documentation is needed. The description adds value by specifying what is being calculated ('gas fees for the airdrop'), which provides context beyond the empty schema, justifying a score above the baseline.

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 ('calculate') and resource ('gas fees for the airdrop'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'calculate_amounts' or 'start_airdrop', which might also involve calculations or airdrop-related 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. It doesn't mention prerequisites (e.g., needing wallet connection first), timing (e.g., before starting an airdrop), or comparisons to siblings like 'calculate_amounts' or 'start_airdrop'.

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

check_balanceB

Check the SOL balance of the connected wallet

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.2/5.0
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 checks a balance, implying a read-only operation, but does not address potential issues like error handling, rate limits, authentication needs, or what happens if no wallet is connected. 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, clear sentence that directly states the tool's purpose without any unnecessary words. It is front-loaded and efficiently conveys the essential information, making it highly concise and well-structured.

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), the description is adequate for a basic read operation. However, without annotations or output schema, it lacks details on return values (e.g., balance format, units) and error conditions, which could be important for an AI agent to use it correctly in a financial context.

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 tool has 0 parameters, and the schema description coverage is 100%, so no parameter documentation is needed. The description appropriately does not include parameter information, aligning with the schema. A baseline score of 4 is applied as it correctly avoids redundancy.

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 ('Check') and the resource ('SOL balance of the connected wallet'), making the tool's purpose immediately understandable. However, it does not explicitly differentiate from sibling tools like 'get_state', which might also retrieve wallet information, leaving room for ambiguity in a crowded toolset.

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, such as 'get_state' or other wallet-related tools. It mentions the 'connected wallet' but does not specify prerequisites (e.g., whether a wallet must be connected first) or exclusions, 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.

connect_crossmint_walletC

Connect a Crossmint wallet to the airdrop server

ParametersJSON Schema
NameRequiredDescriptionDefault
apiKeyYesCrossmint API key
emailYesEmail address associated with the Crossmint wallet

TDQS

C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It states the action ('Connect') but does not disclose behavioral traits like authentication needs, side effects, or what happens upon connection (e.g., if it modifies server state or returns confirmation). This is a significant gap for a tool with no annotations.

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

Conciseness5/5

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

The description is a single, clear sentence with no wasted words. It is appropriately sized and front-loaded, efficiently conveying the core purpose without unnecessary detail.

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 no annotations and no output schema, the description is incomplete. It lacks details on behavioral aspects (e.g., what the connection entails, error handling) and does not compensate for the absence of structured data, making it inadequate for a tool with potential state changes.

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%, so the schema already documents both parameters (apiKey and email) adequately. The description does not add any meaning beyond what the schema provides, such as format examples or usage context, meeting the baseline for high coverage.

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 ('Connect') and the resource ('Crossmint wallet to the airdrop server'), providing a specific purpose. However, it does not explicitly differentiate from the sibling tool 'connect_wallet', which might cause confusion about when to use each.

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 on when to use this tool versus alternatives, such as the sibling 'connect_wallet'. The description lacks context about prerequisites, timing, or exclusions, leaving usage unclear.

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

connect_walletC

Connect a Solana wallet to the airdrop server

ParametersJSON Schema
NameRequiredDescriptionDefault
privateKeyYesThe private key of the Solana wallet (base58 encoded)
rpcUrlNoThe Solana RPC URL to use (optional)

TDQS

C2.9/5.0
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 action ('Connect') but fails to explain what this entails—e.g., whether it establishes a session, requires authentication, has side effects like storing keys, or returns connection status. This leaves critical behavioral traits unspecified for a tool involving private keys.

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, direct sentence that efficiently conveys the core action without unnecessary words. It is front-loaded and appropriately sized for the tool's purpose, with no wasted information.

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 complexity of wallet connection (involving private keys and network settings), the lack of annotations and output schema, and the description's minimal detail, it is incomplete. It doesn't cover behavioral aspects, return values, or error handling, leaving gaps that could hinder correct tool invocation in a security-sensitive context.

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, clearly documenting both parameters ('privateKey' and 'rpcUrl') with their types and optionality. The description adds no additional semantic context beyond what the schema provides, such as format details for the private key or default RPC behavior, so it 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.

Purpose4/5

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

The description clearly states the action ('Connect') and the resource ('a Solana wallet to the airdrop server'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'connect_crossmint_wallet', which appears to serve a similar connection purpose but for a different wallet type, leaving room for ambiguity.

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, such as 'connect_crossmint_wallet' or other wallet-related tools. It lacks context on prerequisites, timing, or exclusions, leaving the agent to infer usage based on the tool name alone.

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

create_tokenC

Create a new Solana token

ParametersJSON Schema
NameRequiredDescriptionDefault
decimalsNoToken decimals (default: 9)
nameYesToken name
supplyYesTotal token supply
symbolYesToken symbol

TDQS

C2.9/5.0
Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Create a new Solana token' implies a write/mutation operation but doesn't specify permissions needed, cost implications (transaction fees), whether it's reversible, or what happens on success/failure. For a blockchain token creation tool, this leaves critical behavioral aspects undocumented.

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 with zero wasted words. It's appropriately sized for a tool with good schema documentation and gets straight to the point without unnecessary elaboration.

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 blockchain token creation tool with no annotations and no output schema, the description is insufficiently complete. It doesn't address critical context like authentication requirements, transaction costs, success/failure outcomes, or integration with sibling tools. The 100% schema coverage helps with parameters but doesn't compensate for missing behavioral and operational context.

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 all parameters well-documented in the schema itself. The description adds no additional parameter semantics beyond what's already in the schema. The baseline score of 3 reflects adequate parameter documentation through the schema alone.

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') and resource ('new Solana token'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'generate_wallets' or 'start_airdrop' which might also create blockchain assets, leaving room for ambiguity in tool selection.

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. There's no mention of prerequisites (like needing a connected wallet), use cases, or exclusions. Sibling tools like 'connect_wallet' or 'generate_wallets' might be related, but no explicit relationships are stated.

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

generate_walletsC

Generate custodial wallets for employees using Crossmint

ParametersJSON Schema
NameRequiredDescriptionDefault
apiKeyNoCrossmint API key (optional, defaults to test key for demo)
employeesYesList of employees in format "name,email" (one per line)

TDQS

C2.9/5.0
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. It states the tool generates wallets but lacks critical behavioral details: whether this is a write operation (likely, but not confirmed), what permissions or authentication are needed beyond the optional API key, if there are rate limits, what happens on success/failure, or if wallets are reusable. The description is minimal and misses key operational context for a tool that likely involves external API calls and data creation.

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 fluff. It's front-loaded with the core action and resource, making it easy to parse. Every word earns its place, and there's no redundancy or unnecessary elaboration.

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 complexity of generating wallets (likely a write operation with external dependencies), no annotations, no output schema, and 2 parameters, the description is incomplete. It doesn't cover behavioral traits, error handling, output format, or integration details with Crossmint. For a tool that could involve financial or sensitive data creation, more context is needed to ensure safe and correct usage by an agent.

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%, so the schema fully documents both parameters (apiKey and employees). The description adds no parameter-specific semantics beyond what's in the schema—it doesn't explain format details for 'employees' (e.g., line breaks) or clarify the 'apiKey' default behavior. With high schema coverage, the baseline is 3, and the description doesn't compensate with extra insights.

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 ('generate') and resource ('custodial wallets for employees') with the specific platform ('using Crossmint'). It distinguishes from siblings like 'connect_crossmint_wallet' or 'check_balance' by focusing on creation rather than connection or querying. However, it doesn't explicitly differentiate from potential wallet-related siblings beyond the generative aspect.

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. It doesn't mention prerequisites (e.g., needing Crossmint setup), exclusions (e.g., not for existing wallets), or comparisons to siblings like 'connect_crossmint_wallet' for linking versus creating. Usage is implied only by the action 'generate' without contextual boundaries.

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

get_stateB

Get the current state of the airdrop process

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.1/5.0
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a 'Get' operation, implying it's likely read-only, but doesn't specify if it requires authentication, has rate limits, or what the state includes (e.g., progress, errors). This leaves significant gaps for a tool with potential complexity.

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, clear sentence that directly states the tool's purpose without any fluff or redundancy. It's front-loaded and efficiently communicates the essential information, making it highly concise and well-structured.

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 lack of annotations and output schema, the description is incomplete. It doesn't explain what the 'state' includes (e.g., status, progress, errors) or behavioral aspects like authentication needs. For a tool that might return complex state information, this leaves the agent with insufficient context.

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 tool has 0 parameters, and schema description coverage is 100%, so there are no parameters to document. The description doesn't need to add parameter semantics, and it appropriately avoids unnecessary details, earning a high score for this context.

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 ('Get') and resource ('current state of the airdrop process'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'start_airdrop' or 'check_balance', which might also relate to airdrop status, so it doesn't reach the highest score.

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. It doesn't mention prerequisites, such as whether an airdrop must be started first, or contrast with other tools like 'check_balance' for wallet status, 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.

C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It implies a write/send operation but lacks details on permissions, rate limits, error handling, or what happens if emails fail. The mention of 'Resend API key' hints at external service use but doesn't clarify 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 with zero waste, front-loaded with the core action. It's appropriately sized for the tool's purpose without unnecessary elaboration.

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 no annotations and no output schema, the description is incomplete for a tool that sends emails. It lacks details on recipients, email content, success/failure responses, and integration with the Resend service, leaving significant gaps for an AI agent to use it correctly.

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%, so the schema already documents all parameters (fromEmail, resendApiKey, subject). The description adds no additional meaning beyond implying emails are for 'wallet access instructions,' which loosely relates to the subject parameter but doesn't enhance schema understanding.

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 ('Send emails') and target ('to employees with wallet access instructions'), providing a specific verb and resource. However, it doesn't differentiate from sibling tools, which are mostly wallet/transaction-related rather than email tools, so this distinction isn't critical but could be noted.

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, prerequisites, or exclusions. It mentions 'employees with wallet access instructions' but doesn't specify if this is for onboarding, updates, or other contexts, leaving usage ambiguous.

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

B3.1/5.0
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. It states the action is to 'perform' an airdrop, implying a write/mutation operation, but doesn't disclose critical behavioral traits like whether this is irreversible, requires specific permissions, has rate limits, or what happens on success/failure. This is inadequate for a mutation tool with zero annotation coverage.

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 with zero wasted words. It's appropriately sized for a simple tool and front-loads the core purpose immediately. Every word earns its place.

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 mutation tool (performing an airdrop) with no annotations, no output schema, and moderate complexity (involving tokens and wallets), the description is incomplete. It lacks information about behavioral consequences, success indicators, error conditions, or relationships to sibling tools like 'generate_wallets' or 'upload_csv'. The agent would struggle to use this tool correctly without additional context.

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 tool has 0 parameters with 100% schema description coverage, so the schema already fully documents the lack of parameters. The description doesn't need to add parameter semantics, and it appropriately doesn't mention any. The baseline for 0 parameters is 4, as the description doesn't mislead about parameters.

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 ('perform') and target ('token airdrop to employee wallets'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'send_emails' or 'upload_csv' which might be related to airdrop workflows, leaving room for improvement in sibling differentiation.

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 (e.g., whether wallets must be generated first via 'generate_wallets'), timing considerations, or exclusions, leaving the agent with no usage context beyond the basic purpose.

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

C2.9/5.0
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 processes data but doesn't clarify whether this is a read-only operation, a mutation, what permissions are required, or what side effects might occur (e.g., data storage, updates). This leaves significant gaps for a tool that likely modifies or uploads data.

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

Conciseness4/5

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

The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized for a simple tool, though it could be slightly more informative to improve completeness without sacrificing brevity.

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 lack of annotations and output schema, the description is incomplete for a tool that likely involves data processing. It doesn't explain what 'process' entails (e.g., validation, upload, transformation), the expected outcomes, or error handling, which are critical for an agent to use it correctly.

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 schema description coverage is 100%, with the single parameter 'filePath' clearly documented in the schema. The description adds no additional meaning about the parameter beyond implying it's for a CSV file, which is already covered. 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.

Purpose4/5

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

The description clearly states the tool's purpose with a specific verb ('Process') and resource ('employee data from a CSV file'), making it easy to understand what it does. However, it doesn't distinguish this tool from potential sibling tools that might also process CSV files or employee data, which prevents 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.

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. There are no mentions of prerequisites, context-specific usage, or comparisons with sibling tools like 'send_emails' or 'create_token', leaving the agent to guess based on the name alone.

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

A3.5/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose with no overlap. For example, connect_wallet and connect_crossmint_wallet handle different wallet types, while calculate_amounts and calculate_fees perform separate calculations. The descriptions make it easy to distinguish between all 12 tools.

Naming Consistency5/5

All tools follow a consistent verb_noun naming pattern (e.g., add_liquidity, calculate_amounts, check_balance). There are no deviations in style or convention, making the tool set highly predictable and readable.

Tool Count5/5

With 12 tools, the set is well-scoped for an HR airdrop process, covering wallet management, token operations, calculations, and communication. Each tool earns its place by addressing a specific step in the workflow without being excessive or insufficient.

Completeness5/5

The tool set provides complete coverage for the HR airdrop domain, including setup (create_token, upload_csv), calculations (calculate_amounts, calculate_fees), wallet management (connect_wallet, generate_wallets), execution (start_airdrop, add_liquidity), and communication (send_emails). No obvious gaps exist in the lifecycle.
