• discord_get_typeC
  2.9/5.0
  Behavior3/5

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

  Annotations already declare readOnlyHint=true, so the read-only nature is covered. The description adds that it returns a 'normalized' schema and only 'one' schema, which gives some behavioral context. However, it does not describe error handling, what keys are returned, or the effect of an invalid type.

  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 with no redundancy. It clearly states the core action and object, earning high marks for efficiency.

  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?

  For a tool with one parameter, no output schema, and minimal annotations, the description is too sparse. The key missing piece is the meaning of the 'type' parameter, and there is no guidance on usage, making the tool difficult to invoke correctly without additional context.

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

  Parameters1/5

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

  The input schema defines a single required 'type' parameter with no description (0% coverage), and the description does not explain what 'type' represents or how to format it. The agent is left to infer that 'type' is the schema type name, which is a significant gap.

  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 uses the specific verb 'Return' and resource 'normalized Discord OpenAPI component schema', which clearly identifies the tool's function. It distinguishes from siblings like discord_get_endpoint or discord_call_endpoint, though it doesn't explicitly name alternatives. The scope is constrained to a single schema.

  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 information on when to choose this tool over alternatives. It does not mention any exclusions, prerequisites, or relationships to sibling tools. The usage context is only implied by the tool's name and description.

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

• discord_call_endpointB
  3/5.0
  Behavior3/5

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

  The description adds some behavioral context beyond annotations: it indicates that the tool validates the endpoint before calling, and only 'cataloged' endpoints are allowed. However, it does not disclose the confirmation flow, potential side effects of calling, or any authentication/rate-limit considerations. The annotations already indicate non-read-only and open-world semantics, so the bar is lower, but there is room for more detail.

  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, efficiently worded sentence that front-loads the action and resource. It is appropriately concise, though given the tool's complexity it might benefit from more detail, but the structure itself is clear.

  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?

  Despite having annotations, the description is too sparse for a tool that executes external HTTP calls. It does not explain the purpose of the confirm flag, how files or body are used, what the reason field is for, or what outputs are expected. The absence of an output schema and 0% parameter coverage makes this description insufficient for safe and correct invocation.

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

  Parameters1/5

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

  Schema description coverage is 0%, and the description does not compensate for the 7 parameters. It only mentions 'endpoint' by name without explaining its significance or the roles of body, files, confirm, reason, pathParameters, or queryParameters. This leaves the agent to infer meanings from parameter names alone, which is inadequate.

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

  Purpose5/5

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

  The description clearly states the action ('Validate and call') and the resource ('one cataloged Discord Bot HTTP endpoint'). It distinguishes this tool from siblings by focusing on executing an endpoint rather than searching, retrieving, or refreshing schema.

  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 explicit guidance on when to use this tool versus alternatives. It does not mention sibling tools or any prerequisites, exclusions, or decision factors. There is no 'use when' or 'instead of' context.

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

• discord_search_endpointsA
  3.5/5.0
  Behavior3/5

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

  Annotations already declare readOnlyHint=true, so the read-only nature is covered. The description adds the 'fuzzy-search' behavior and the fact that it searches a catalog, which is useful context. However, it doesn't disclose result format, sorting, or any limitations of the fuzzy search.

  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 sentence, extremely concise, with the key verb and resource front-loaded. Every word earns its place, making it an efficient statement.

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

  Completeness2/5

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

  Given the tool's simplicity, the description is still incomplete: it omits parameter semantics, return value expectations, and any usage context relative to siblings. With zero schema property descriptions and no mention of search/limit, the agent cannot optimally select or invoke this tool without additional inference.

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

  Parameters2/5

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

  Schema description coverage is 0%, and the description never mentions the 'search' or 'limit' parameters. The word 'fuzzy-search' implies the search parameter's role, but 'limit' is entirely unexplained. The description provides no meaningful parameter information beyond what the schema exposes (types/defaults).

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

  Purpose5/5

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

  The description uses the specific verb 'fuzzy-search' and identifies the resource as 'cataloged Discord Bot HTTP API endpoints,' clearly distinguishing it from sibling tools like discord_get_endpoint and discord_call_endpoint by focusing on search over a static catalog.

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

  Usage Guidelines3/5

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

  The description provides no explicit guidance on when to use this tool versus alternatives. The sibling list is present, but the description doesn't state e.g., 'Use this to discover endpoints before calling them with discord_call_endpoint.' Usage is only implied by the tool name.

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

• discord_get_endpointA
  3.6/5.0
  Behavior3/5

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

  Annotations already declare readOnlyHint=true, and the description adds 'normalized schema' indicating a read/transform operation. It does not describe behavior for invalid endpoints or pagination, but annotations cover the safety profile, so the description adds modest context.

  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, well-structured sentence with no filler. It is front-loaded with the verb and resource, earning every word.

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

  Completeness3/5

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

  For a simple single-parameter tool with annotations and no output schema, the description is adequate but leaves gaps: no endpoint format guidance and no indication of return structure beyond 'normalized schema.' Sibling names help, but the description itself is minimal.

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

  Parameters2/5

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

  Schema coverage is 0%, so the description must explain the 'endpoint' parameter. It only says 'Discord Bot endpoint,' which does not clarify expected format (e.g., path, name, ID). The param name is somewhat self-explanatory but lacks critical detail for correct invocation.

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

  Purpose5/5

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

  The description uses a specific verb 'Return' and a resource 'normalized schema for one Discord Bot endpoint,' which clearly differentiates from siblings like discord_search_endpoints (search) and discord_call_endpoint (execute). It is concise and unambiguous.

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

  Usage Guidelines3/5

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

  The description implies usage for retrieving a single endpoint's schema, but does not explicitly state when to choose this over siblings. No exclusions or alternatives are named; however, the word 'one' hints at distinct use from search or refresh.

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

• discord_refresh_schemaA
  4.2/5.0
  Behavior4/5

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

  Annotations already indicate non-readonly, idempotent, and open-world behavior. The description adds valuable context beyond annotations by disclosing that the process involves validation, filtering, and atomic installation, which implies safe replacement without partial states. No contradictions with 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?

  A single sentence with a clear sequence of verb-led actions, front-loaded with the primary verb 'Refresh' in the tool name and descriptive details. Every word earns its place with no redundancy.

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

  Completeness4/5

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

  For a parameterless tool with no output schema, the description gives a complete lifecycle of the operation: fetch, validate, filter, and install atomically. It could specify return values or failure modes, but idempotence and open-world hints cover some context. The description is adequate for its simple scope.

  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 zero parameters, and schema description coverage is 100%. The baseline for no parameters is 4, and the description does not need to add parameter details since there are none to document.

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

  Purpose5/5

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

  The description clearly states the action ('Fetch, validate, filter, and atomically install') and the specific resource ('stable Discord Bot schema'). It distinguishes itself from sibling tools focused on searching and calling endpoints, making the purpose unambiguous.

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

  Usage Guidelines3/5

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

  The description implies this tool is used to refresh the Discord Bot schema to a stable version, but it does not explicitly state when to use it over alternatives or provide exclusions. No comparable tool is mentioned, so usage context is only inferred.

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