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

No annotations are provided, and the description only states the return value ('combat result with damage dealt and enemy status'). It fails to disclose important behaviors such as resource consumption, cooldowns, or failure conditions, which are critical for a combat action.

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 concise with one line plus Args/Returns. However, it could be more front-loaded with the core action phrase. Minor structure improvement possible.

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 existence of an output schema (not provided) and simple parameters, the description covers basic combat use. However, it lacks details on game mechanics like skill enumeration or turn mechanics, 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 0%, but the description fully compensates by explaining both parameters: 'target' as enemy name and 'skill' as skill to use with default and class skill note. This goes beyond the schema.

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

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

The description clearly states the action as 'Attack an integration villain' and explains the target and skill parameters. It effectively distinguishes from sibling tools like defend, flee, and rest.

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

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

No explicit guidance is provided on when to use this tool versus alternatives (e.g., when to flee or defend). The usage is implied from the game context but lacks exclusion criteria.

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

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

No annotations are provided, so the description carries the full burden. It discloses that the tool creates a character and returns starting stats, and it clarifies the role options. It does not mention potential side effects like saving, but for a creation tool it is sufficiently transparent.

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 relatively concise, using a table-like format for roles. It front-loads the main purpose and includes necessary details without excessive verbosity.

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 (2 parameters, no nesting) and the presence of an output schema, the description covers the purpose, parameters, roles, and return value adequately. It does not explain every detail but is complete enough for the 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 has 0% description coverage, so the description must compensate. It provides brief descriptions for 'name' and 'role' and enumerates the role options with explanations. This adds some meaning beyond the schema but does not deeply elaborate on parameter constraints or 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 'Create an Integration Hero and begin your quest' with a specific verb and resource. It distinguishes the tool from siblings which involve combat, exploration, and other actions.

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 explains the roles and their purposes, guiding the user on which role to choose for different tasks. It implicitly indicates when to use this tool (starting a game) but does not explicitly exclude alternative tools.

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?

Discloses damage reduction and retry logic, but lacks details on how retry logic works or resource costs. Without annotations, description carries burden but is partially transparent.

Clearly states defensive stance, 50% damage reduction, and retry logic trigger. Differentiates well from siblings like attack and flee.

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?

Implied usage (when defending), but no explicit when-to-use or when-not-to-use guidance. No mention of alternatives.

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. It only says 'Returns: Diagnostic result' without any detail on what that means, side effects, or required permissions. The behavior is too vague.

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

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

The description is very short and efficient with no wasted words. However, it is too brief to be fully helpful, sacrificing completeness for brevity.

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 is simple with one parameter and an output schema exists, the description could be minimal. However, it lacks explanation of what diagnostic codes are or how to use them, making it incomplete 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 add meaning. It only repeats the parameter name 'code' and says 'Diagnostic code sequence', which is essentially a rewording of the schema. No information on valid values, format, or constraints.

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 runs system diagnostics with a diagnostic code. The verb 'run diagnostics' and resource 'system' make the purpose clear, distinguishing it from sibling tools which are all game actions.

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. The description does not mention any context or constraints such as prerequisites or when not to use it.

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

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

With no annotations, the description carries full burden. It only states that equipping changes equipment and returns confirmation, but fails to disclose whether equipping replaces existing items, side effects, or restrictions on equipping multiple items of the same type.

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 short, includes a structured Args/Returns format, and front-loads the main purpose. The Returns line is slightly redundant but not excessive.

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 one-parameter tool with output schema, the description is mostly complete but lacks behavioral details such as what happens if the item is not in inventory or if equipping replaces existing gear. These gaps are notable given no annotations.

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 basic meaning for the sole parameter 'item' by stating 'Item name to equip' in the Args section, but does not specify valid names or format. With 0% schema coverage, more detail would be beneficial.

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 'Equip' and specifies the resource as 'connector (weapon), error handler (armor), or accessory from inventory.' This distinguishes it from siblings like 'use_item' and 'pickup.'

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 equipping items but does not explicitly state when to use this tool vs alternatives, nor does it mention prerequisites (e.g., item must be in inventory).

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?

Without annotations, the description carries the behavioral burden. It discloses that enemies are immune until examined, a key trait, but does not cover other behaviors (e.g., what happens if target doesn't exist, if it consumes an action, or if it can be used on items). The mention of 'system feature' in the description but not in Args causes slight inconsistency.

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: two sentences plus formatted Args/Returns. Every sentence adds value, and the critical hint about undocumented enemies is front-loaded. 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?

The tool has one parameter and an output schema (implied but not shown). The description covers core behavior and a special mechanic. However, it lacks details on error cases or whether examine can be used multiple times on the same target. Given the game context, this is nearly complete.

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

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

Schema coverage is 0%, so the description must interpret the target parameter. It specifies 'Name of enemy or item to examine,' adding meaning beyond the raw string type. This is sufficient for a single parameter, though 'system feature' is omitted from args.

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 that the tool examines an enemy, item, or system feature in detail, providing a specific verb and resource. It distinguishes from siblings like attack or view_status by focusing on detailed inspection, and the note about Undocumented API enemies reinforces its unique role.

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 when to use the tool ('Critical for Undocumented API enemies'), but does not explicitly state when not to use it or mention alternatives like view_status. Usage context is suggested but not fully elaborated.

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. It discloses what information is returned (room details, items, connectors, integration villains) and that it's a read-only operation. However, it does not mention any side effects, rate limits, or prerequisites.

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?

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 disclose behavioral details. It does not mention that loading overwrites current state, potential side effects, or error handling, which are critical 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 three sentences, front-loaded with the core purpose, and contains no unnecessary words or 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?

Given the single parameter and existing output schema, the description is mostly complete. It could mention what happens if save_id is invalid or that it overwrites current state, but it suffices for the basic use case.

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?

With 0% schema description coverage, the description provides essential context: 'Save ID from previous save_game call', telling the agent where to obtain the value and how to use it.

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

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

The description clearly states 'Restore from a previous checkpoint', specifying the verb and resource. It distinguishes itself from siblings like save_game (save) and explore (navigate), providing clear intent.

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 after save_game by referencing 'previous save_game call', but lacks explicit when-to-use or when-not-to-use guidance and does not mention alternatives.

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 bears full responsibility. It mentions return values ('New room description or failure message') but omits details such as obstacles, resource consumption, 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 brief and well-structured, with a one-line summary followed by clear Args/Returns sections. Every sentence serves a purpose.

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

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

Given the tool's simplicity (1 parameter, output schema present), the description covers the main functionality. However, it could mention edge cases or prerequisites for a higher score.

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%, and the description only paraphrases the parameter type ('Cardinal direction to move'), adding no new information beyond the enum values in the schema.

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

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

The description clearly states 'Navigate to an adjacent system' with a specific verb and resource, and the direction parameter is well-defined. Among sibling tools like 'explore' and 'flee', this tool is uniquely positioned for cardinal movement.

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

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

No explicit guidance is provided on when to use this tool versus alternatives like 'explore' or 'flee'. The description implies basic movement but does not specify exclusions or 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?

Without annotations, the description fails to disclose behaviors such as what happens if the item is not present, whether the action can fail, or if it is destructive. The return value is minimally described as 'Pickup confirmation' without further detail.

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 short but includes redundant 'Args:' and 'Returns:' sections that echo the schema. It is not overly verbose, but some structure could be improved.

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 pickup tool, the description covers the basic purpose and parameter but omits important context like error handling or whether the tool consumes game actions. The return value is vague, and no output schema is provided despite the signal indicating one exists.

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%, forcing the description to compensate. However, it only repeats 'Item name to pick up,' adding no format, constraints, or examples beyond the schema's type string.

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 specifies the action 'Pick up' and the resource 'item or connector from the current room,' effectively distinguishing it from sibling tools like attack, examine, or use_item.

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 (e.g., examine to check item presence). The description only mentions the context 'current room' but offers no 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?

Without annotations, the description partially discloses behavior: it recovers Uptime and API Credits and has a 20% random encounter chance. However, it does not state if resting consumes turns or has other side effects, leaving some behavioral gaps.

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 concise with two sentences. The first sentence states the primary purpose, and the second adds an important warning. No redundancy, well-structured.

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 output schema exists, the description adequately explains return values ('Rest results and possible encounter'). It covers the tool's core function and risk, though could elaborate on what rest results entail.

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 no parameters, so the description does not need to provide param info. The input schema is fully covered. Baseline for 0 parameters is 4.

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: resting to recover Uptime and API Credits. It also mentions a random encounter risk, adding specificity. While it distinguishes from siblings like 'attack' or 'explore', it does not differentiate from other recovery methods like 'use_item'.

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 when to use (when needing to recover resources) but does not provide explicit guidance on when not to use or mention alternatives. The warning about random encounters adds context.

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

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

No annotations are provided, so the description bears full responsibility. It indicates saving a checkpoint with no side effects mentioned. However, it does not specify whether saves overwrite or if there are limits, which could be important for safe usage.

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?

Two concise sentences with no redundant information. The key action and return are front-loaded.

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

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

For a simple tool with no parameters, the description is sufficient, specifying the return value. It could mention overwrite behavior, but overall completeness is high given the tool's simplicity.

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?

There are no parameters (schema coverage 100%), and the description correctly omits param details. Baseline 4 applies per rubric for 0-parameter tools.

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

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

The description clearly states the action ('Create a checkpoint') and the result ('Returns save ID for later restoration'). It distinguishes from sibling tools like load_game, which restores a save.

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 state when to use this tool vs. alternatives. However, the sibling list includes load_game, implying the usage context, but no guidance on when to save or when not to.

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 discloses that the tool consumes an item and applies an effect to a target (defaulting to self), but does not mention consequences for missing items, invalid targets, or whether the action is reversible. The consumption is implicitly destructive but not explicitly stated, which is a gap for agents needing safety details.

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 concise, starting with a clear one-line purpose. The Args and Returns sections are formatted cleanly with bullet-like structure, making it easy to scan. Every sentence serves a purpose: purpose statement, parameter explanations, and return indication. No superfluous text.

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 (2 parameters, 1 required) and the existence of an output schema, the description covers essential aspects for agent invocation. It explains parameters, default behavior, and return type. However, it omits edge cases like item not in inventory or invalid target, which would improve completeness. Overall, it is adequate for the task.

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 add meaning. It provides an example for 'item' ('Job Retry Potion') and explains 'target' as 'Target of item effect' with the default 'self.' This adds valuable context beyond the schema's type-only definition, compensating well 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 begins with 'Use a consumable from inventory,' which clearly states the action (use) and the resource (consumable item). This distinguishes it from sibling tools like 'equip' (for equipping, not consuming) and 'examine' (for inspection). The verb 'use' combined with 'consumable' is specific and unambiguous.

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 when to use (to consume an item from inventory) but does not explicitly state when to avoid this tool or contrast it with alternatives like 'equip' or 'examine.' With 15 sibling tools, an explicit usage note would help, but the default target parameter and item example provide some implicit guidance.

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 handles behavioral disclosure. The term 'View' indicates read-only operation with no side effects. However, it does not mention authentication requirements or error conditions, though these are likely minimal for a parameterless function.

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 with no unnecessary words. It leads with the verb 'View' and concisely lists the items visible, followed by a return 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?

Given the tool's simplicity (0 parameters, output schema present), the description sufficiently conveys purpose and output. It could mention that it's safe to call anytime, but overall it meets completeness for its complexity level.

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?

There are no parameters, and schema coverage is 100% trivial. The description adds value by enumerating the content of the view (Uptime, API Credits, etc.), going beyond the empty schema.

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

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

The description clearly states the verb 'View' and specifies multiple resources: Uptime, API Credits, stats, inventory, and status effects. It distinguishes this tool from action-oriented siblings (e.g., attack, explore) by being a read-only status viewer.

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 use for checking character status but does not explicitly state when to use versus alternatives like examine or explore. No exclusions or 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.
