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

There are no annotations, so the description carries the full burden of behavioral disclosure. It states the action but does not warn that this is a destructive, irreversible bulk operation, nor does it mention potential consequences, required permissions, or the response format. The word 'TODAS' implies bulk impact but fails to elaborate on safety or side effects.

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

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

The description is a single, concise sentence in Spanish that front-loads the action ('Cancela') and clearly identifies the target. There are no wasted words or redundant content. This is an appropriate size for the simple operation.

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 destructive bulk operation with no annotations and no output schema, the description is incomplete. It does not mention what happens after cancellation, whether the action is reversible, how to handle errors (e.g., no open orders), or any response details. This is insufficient for an agent to understand the full context of the tool.

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

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

The input schema has one required parameter 'symbol' with no description. The description mentions 'de un simbolo,' which clarifies that the symbol identifies whose orders will be canceled, but it does not explain the expected format (e.g., 'BTCUSDT') or any additional nuances. Given 0% schema coverage, the description provides only minimal compensation.

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 with a specific verb ('Cancela') and resource ('TODAS las ordenes abiertas de un simbolo'), meaning 'Cancels ALL open orders of a symbol.' The word 'TODAS' distinguishes it from the sibling tool cancel_order, which presumably cancels a single order.

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 does not explicitly mention when to use this tool or provide alternatives. Usage is implied from the purpose: use when you want to cancel all open orders for a given symbol, rather than individual orders. There is no guidance on exclusions or prerequisites.

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

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the action without mentioning side effects, irreversibility, authentication requirements, or error behavior. This is insufficient for a mutation tool.

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

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

The description is a single sentence that is front-loaded and contains no fluff. Every word contributes to the meaning.

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?

The description conveys the basic action and parameters but provides no information about return values, errors, or post-conditions. Given the absence of an output schema and annotations, this is functionally incomplete for an agent to fully anticipate the tool's 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?

The schema has 0% description coverage, but the description clarifies that order_id is the identifier of the order to cancel and symbol is the trading symbol. This adds meaningful semantics beyond the raw schema, though it lacks deeper constraints or format details.

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

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

The description uses the specific verb 'Cancela' (cancels) with the resource 'orden' (order), and specifies the exact means ('por su orderId en el simbolo dado'). This clearly distinguishes it from sibling tools like place_order and cancel_all_orders.

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 clearly implies the use case: you need an orderId and a symbol to cancel a specific order. It does not explicitly mention alternatives or exclusions, but the context is unambiguous, so a 4 is appropriate.

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 must carry the behavioral disclosure burden. It lists the returned fields (volume, change %, high/low) but omits response format, error behavior, and whether the 24h stats are rolling or daily.

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

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

A single, focused sentence with a practical example. No filler or redundant information; every word contributes.

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 one-parameter stats tool, the description names the included metrics and provides an example. Without an output schema, it could describe the response shape or error cases, but the listed fields give adequate functional 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?

The schema provides only the parameter name 'symbol' with no description (0% coverage). The description compensates by explaining that the parameter is a trading symbol and gives a concrete example ('ETHUSDT'), clarifying the expected format.

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 returns 24h statistics for a symbol, listing volume, change percentage, and high/low. This distinguishes it from siblings like get_price and get_klines, though it lacks an explicit verb.

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 intended use is implied: fetch 24h market stats for a symbol. The example clarifies the symbol parameter, but no explicit guidance is given about when to prefer this over alternatives like get_price or get_klines.

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 responsibility. It discloses the authentication requirement (requires signature) which is a useful behavioral trait beyond the schema, but it does not explicitly state the read-only nature or other potential side effects. This is a minimal but acceptable transparency level.

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 two short sentences, front-loading the purpose and then the requirement. Every word serves a purpose, with no wasted 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 zero-parameter tool with no output schema and no annotations, the description adequately covers what it returns (balances and permissions) and its prerequisite (signature). While it lacks explicit return format, the information provided is sufficient for basic invocation.

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

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

The tool has zero parameters, so the description needs no parameter semantics. The baseline of 4 applies because there is no need to compensate for undocumented 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 identifies the resource: 'Balances y permisos de tu cuenta spot' (balances and permissions of your spot account), which is specific and distinct from market data and trade execution siblings. However, it lacks an explicit verb and does not name alternative tools, so it is clear but not explicit 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.

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

There is no guidance on when to use this tool versus alternatives. The only additional note, 'Requiere firma' (requires signature), is a prerequisite rather than a usage context or exclusion.

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

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

The description discloses interval choices and a limit cap of 1000, but gives no information about the returned data structure, ordering, time ranges, or potential side effects. With no annotations, the description carries the full burden and falls short.

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

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

The description is extremely brief and to the point, using two short sentences. The first sentence states the purpose, and the second lists constraints. It could be better structured, but it is 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?

With no output schema or annotations, the description needs to explain what a kline is and what the response contains. It only says 'velas' without defining OHLCV structure, ordering, or error handling, making it incomplete for an 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?

The description adds meaning for interval (listing common values like 1m, 1h, 1d) and limit (max 1000), which are not explained in the schema. However, symbol is only implied and not elaborated, and defaults are not mentioned.

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

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

The description states 'Velas (candlesticks) de un simbolo' which clearly identifies the tool's purpose as retrieving candlestick data for a symbol. This distinguishes it from sibling tools like get_price (current price) and get_order_book.

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 lacks contextual clues about when klines are needed (e.g., historical analysis) or when to prefer other tools like get_price.

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

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

The description mentions the authentication requirement ('Requiere firma') and user-specific scope ('tuyos'), which are useful behavioral details. However, with no annotations, it lacks disclosure about the return format, result ordering, or read-only nature.

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

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

The description is extremely concise, with every word serving a purpose. The main action is front-loaded and the additional note about the signature is kept separate and brief.

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 output schema and no annotations, the description should explain what the tool returns and any output behavior. It only covers the input symbol and auth requirement, leaving limit semantics and return structure missing.

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 0%, so the description must compensate. It clarifies 'symbol' as the trading pair ('para un simbolo'), but provides no meaning for 'limit', leaving a required parameter under-explained.

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: retrieving the user's own trade history for a given symbol. The phrase 'tuyos' (yours) and 'para un simbolo' (for a symbol) specify the scope, differentiating it from siblings like get_account or get_open_orders.

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 only notes that a signature is required, which is an authentication prerequisite rather than a usage criterion.

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 must carry the behavioral disclosure burden. It discloses one behavior (filtering by symbol), but does not mention auth requirements, pagination, return format, or behavior when no symbol is passed. This is minimal context for a trading 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 extremely concise, consisting of two short sentences. It front-loads the main concept ('Ordenes abiertas') and immediately follows with the filter condition. No redundant words, though the first sentence is a fragment rather than a complete statement.

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

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

For a simple tool with one optional parameter and no output schema, the description is adequate but not complete. It explains the symbol filter but does not state what the return value is, whether it returns all orders for the account, or any limitations. Given the low complexity, it hits the minimum threshold.

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

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

The input schema has zero description coverage for the symbol parameter, and the description compensates by explaining its effect: 'Si pasas symbol, filtra por ese par.' This provides clear semantics for the only parameter, though it leaves format specifics to the schema.

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

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

The description 'Ordenes abiertas' is a noun phrase that essentially restates the tool name (get_open_orders), lacking an explicit verb like 'lists' or 'returns.' It does clarify the resource and adds a filter condition, but the core action is implied rather than stated, making it vague.

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 about when to use this tool versus alternatives. The description only mentions an optional symbol filter and does not reference sibling tools such as get_my_trades or get_account, nor does it explain use cases or exclusions.

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

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only describes the resource (order book) and valid limit values, but does not mention safety (read-only nature), response format, aggregation behavior, or any other nuances. This is a minimal description that adds little beyond what the tool name suggests.

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

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

The description is a single sentence that front-loads the resource (order book) and then provides the limit options. Every word earns its place; it is concise and efficient with no redundant 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 simple read tool with no annotations and no output schema, the description is adequate but thin. It clearly states the purpose and limit values, but lacks usage guidance and behavioral details. It is minimally viable but leaves gaps such as when to use it and what the response looks like.

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

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

Schema coverage is 0%, so the description must compensate. It does add meaning for the 'limit' parameter by listing valid values (5,10,20,50,100,500,1000), which is not in the schema. However, it does not explain the 'symbol' parameter beyond the obvious property name, and there are no descriptions for either parameter in the schema itself. Overall, the description partially compensates for the lack of schema descriptions.

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: it retrieves the order book (bids/asks) for a given symbol. This is a specific verb+resource combination that distinguishes it from sibling tools like get_price and get_klines, which serve different data retrieval purposes.

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 does not mention scenarios, prerequisites, or exclusions. While the tool name and description imply it is for order book data, there is no explicit context for when an agent should choose this over siblings.

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 burden. It states the function is read-only by nature ('Precio actual'), but it does not disclose any edge cases, response format, or potential errors. For a simple getter, this is adequate but minimal.

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 two sentences long, front-loaded with the purpose and including a helpful example. No filler or redundancy.

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

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

No output schema exists, so the description should explain the return value. It only states 'current price' but does not disclose whether the response is a plain number or a structured object. Given the tool's simplicity, this is a notable gap 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 0%, so the description must compensate. It provides an example symbol='BTCUSDT', which clarifies the expected format (uppercase base/quote pair). This adds meaningful value beyond the bare property name, though it does not enumerate all possible symbols.

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 returns the current price of a symbol ('Precio actual de un simbolo'). It uses a specific verb and resource, and the example symbol='BTCUSDT' clarifies the expected input. This distinguishes it from sibling tools like get_klines (historical data) and get_order_book.

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 for obtaining current price but does not explicitly contrast with alternatives like get_24h_stats or get_klines. The context is clear enough, but no when-not-to-use guidance is provided.

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 mentions parameter constraints (price only for LIMIT, time_in_force only for LIMIT) but does not disclose that placing an order executes a financial transaction, may require permissions/funds, or what happens after submission. No info on idempotency or error cases.

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 compact, bullet-list format covering each parameter succinctly with examples. No redundant or filler content; every line adds 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?

The tool is moderately complex with no output schema or annotations. The description covers purpose and parameters well but omits usage context, return values (e.g., order ID), and operational behavior. It is adequate for parameter reference but not fully complete for decision-making.

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

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

Schema coverage is 0%, but the description fully compensates by explaining each parameter with examples and constraints. It defines symbol, side, order_type, quantity (base asset), price (required only for LIMIT), and time_in_force (GTC/IOC/FOK, only LIMIT), adding meaning beyond the bare schema.

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

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

The description clearly states 'Crea una orden de compra/venta' (creates a buy/sell order), using a specific verb and resource. This distinguishes it from siblings like get_price, cancel_order, and withdraw, as it is the only one that places orders.

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 through the purpose but does not explicitly state when to use this tool versus alternatives (e.g., 'use get_price to check prices before placing an order'). There is no mention of prerequisites, exclusions, or context like market vs limit behavior beyond parameter 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, the description takes on full responsibility for behavioral disclosure. It discloses the disabled-by-default state, the required config flag and permission, and a risk warning. However, it omits crucial details like irreversibility of withdrawals and potential failure modes, which would be expected for a high-risk financial operation.

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

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

The description is compact, front-loaded with the core action, and then efficiently presents activation and risk context in a few short sentences. Every sentence contributes critical information without redundant 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?

The description covers activation context and risk, which is essential, but fails to describe what happens after a withdrawal is submitted (e.g., response format, transaction confirmation, or irreversibility). Given the absence of an output schema and the high stakes, this is a notable gap.

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 0%, so the description must compensate for parameter explanations. It adds only a hint that the address is external, but does not explain coin type, amount units, or the optional network parameter. This leaves substantial ambiguity for the four 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 verb 'Retira fondos' (withdraw funds) and the resource 'direccion externa' (external address), distinguishing this from trading and account tools among siblings. It also uniquely identifies the operation as a withdrawal, making its purpose unmistakable.

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?

Provides explicit activation prerequisites ('DESACTIVADO por defecto', 'ENABLE_WITHDRAWALS=true', API key permission) and a risk warning, effectively telling the agent when the tool can and should be used. This goes beyond typical usage guidance by specifying the condition under which it is disabled.

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