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

No annotations are provided, so the description must alone disclose behavioral traits. It does state 'No muestra el token', which is a key safety disclosure. However, it omits details about the response format (e.g., boolean, object), error conditions (e.g., if no configuration exists), and whether the tool has side effects. Given the absence of annotations, the description is insufficiently 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 a single sentence that efficiently conveys the purpose and a key behavioral note. It is front-loaded with the main action ('Indica si') and contains no redundant words. Every word 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?

The description is adequate for a simple read-only tool but lacks completeness because there is no output schema and the description does not hint at the return value structure or possible states. For example, it does not mention what 'indica' produces (boolean? status object?). Without annotations or output schema, the description should be more thorough.

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 schema coverage is 100%. Per rubric, 0 parameters have a baseline score of 4. The description adds meaning beyond the empty schema by explaining what the tool checks (token status, base URL) and what it does not reveal (token itself). No further clarification needed.

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: to indicate whether the MCP has a configured token and the base URL. The verb 'Indica' combined with the specific resource ('token configurado', 'URL base') makes the action unambiguous. This distinguishes it from sibling tools like zyta_login (which performs login) and zyta_whoami (which shows current user).

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 versus alternatives. While the purpose implies it is a readiness check before other operations, there is no guidance on prerequisites, when-not to use, or comparison with zyta_login or zyta_whoami. The agent must infer usage 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 effectively discloses the tool's actions (deleting token in memory and file) and its boundaries (no browser session closure). This is transparent for a simple logout 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 exceptionally concise (two sentences), front-loaded with the main action, and every sentence adds value without redundancy.

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

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

Given zero parameters and no output schema, the description fully covers the tool's behavior and limitations. It is complete for a simple disconnect operation.

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, so the description cannot add meaning beyond the schema. Baseline score of 4 is appropriate as the tool's behavior is fully described without needing parameter 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 clearly states the tool's purpose (closing the MCP agent session) with specific verbs and resources, and distinguishes itself from siblings by explaining what it does not do (close browser session).

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?

While the description does not explicitly state when to use or not use this tool, the context is clear and the caveat about browser session provides helpful guidance. It could be improved by mentioning alternatives like zyta_login.

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 performs a write operation ('registra actuaciones') and that the backend uses AI. It does not mention permissions, reversibility, or side effects. For a mutation tool, more transparency on behavior would be beneficial.

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 sentences, front-loaded with the core purpose. Includes the API endpoint as added detail. Every sentence serves a purpose with no fluff.

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 a write operation with 3 parameters, no output schema. The description explains input and resolution logic, but lacks information about the return value or confirmation feedback. While the context is reasonable, completeness would improve with output details.

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 100%, and the description adds context beyond the schema: message is free text task, link is optional, expedienteId is UUID for specific case. It explains the AI resolution logic when expedienteId is omitted, adding value.

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 'Registra' and resource 'actuaciones en una causa sin portal'. It specifies that it works from a free text message and uses AI to resolve the case if no expedienteId is provided. This distinguishes it from sibling tools that handle other judicial functions.

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 when to use the tool: for cases without portal, and gives two methods—either let AI resolve or provide expedienteId. It also mentions optional link. However, it doesn't explicitly state when not to use it or compare to alternatives (e.g., tools for cases with portal).

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, and the description does not disclose behavioral traits such as authentication requirements, rate limits, or side effects. It does not explicitly state that this is a read-only operation, leaving assumptions to the agent.

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 (one sentence and endpoint), front-loading the purpose. It is efficient but could include a brief note on typical use or response structure without becoming verbose.

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, no output schema, no annotations), the description is minimally adequate. It explains the tool's core purpose but omits details about the response format or what 'actuaciones' entails, which could aid the 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 coverage is 100% (one parameter with description), so baseline is 3. The description adds no extra meaning beyond the schema; it only restates the parameter implicitly via the endpoint.

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 retrieves 'Detalle de un expediente judicial con actuaciones' (detail of a judicial file with actions) and includes the HTTP method and endpoint. It uses a specific verb (detail/get) and resource (expediente judicial), distinguishing it from siblings like list.

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

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

No guidance on when to use this tool versus alternatives like zyta_judicial_expedientes_list or zyta_judicial_cursor_registrar_actuacion. The description lacks context about prerequisites or typical scenarios.

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 detail behavioral traits. It discloses the HTTP method but omits common list behaviors like pagination, ordering, or data limits. It does not explicitly state 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: two sentences that front-load the main action, mention optional filtering, and include the API path. No wasted words.

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 list tool with one optional parameter, the description covers the core functionality. However, it does not specify return fields, pagination, or any default behavior. With no output schema, a bit more detail would improve completeness.

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 100% with a well-described optional parameter. The description redundantly mentions the portal filter but adds no new meaning beyond the schema. Baseline 3 is appropriate.

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

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

The description clearly states it lists the user's judicial cases, optionally filtered by portal. It includes the HTTP method and path, distinguishing it from sibling tools like zyta_judicial_expediente_get (which retrieves a single case).

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 the tool is for listing the user's own cases with optional filtering, but does not explicitly state when to use it versus alternatives or provide exclusions. It lacks guidance on prerequisites or complementary 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?

With no annotations, the description carries the full burden but only states the basic function: fetching connection status. It does not disclose potential side effects, error conditions, or performance characteristics. The description is adequate for a simple query but lacks depth.

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?

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 simplicity (no parameters, no output schema), the description provides the essential purpose. However, it omits details about the response format or possible status values, which would be helpful for an agent to handle the output correctly.

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 no parameters, so schema coverage is 100%. The description does not need to add parameter details. A baseline of 4 is appropriate since no additional information is required.

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 checks the connection status of specific judicial portals (PJN and SCBA) and that it uses the same user as the JWT token. It also includes the HTTP method and path, making the purpose unambiguous and distinct from sibling tools like zyta_auth_status.

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

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

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

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

No annotations provided, but the description discloses behavior: access_token can be passed as parameter or via env variable; email+password performs POST /auth/login; device flow opens browser and requires dashboard. It is transparent about dependencies and alternatives, though it does not mention session handling post-login.

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?

Three sentences, front-loaded with the most critical information (mandatory usage). Each sentence serves a purpose: prerequisite, ordered options, fallback advice. No unnecessary words.

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 absence of an output schema and the presence of sibling tools (zyta_auth_status), the description covers prerequisites, methods, and fallbacks comprehensively. It does not detail post-login behavior, but that is likely handled by zyta_auth_status.

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 100%, and the description adds significant context beyond the schema: it explains the priority and rationale for each parameter (e.g., 'access_token manual (alternativa al device flow)', 'Con password hace POST /auth/login (sin depender del dashboard)'). This helps an agent choose the right input for the situation.

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 is required before any other if no session exists, and lists three authentication methods (access_token, email+password, device flow). It distinguishes itself from sibling tools by being the prerequisite for all others.
