Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.2
Disambiguation5/5
Each tool has a clearly distinct purpose, with descriptions explicitly differentiating similar operations (e.g., close_task vs delete_task, create_task vs create_tasks_batch). Overlapping tools are well distinguished by documentation.
Naming Consistency5/5
All tool names follow a consistent verb_noun pattern using lowercase snake_case (e.g., create_project, list_tasks, update_column). The naming is predictable and uniform across all entities.
Tool Count3/5
With 39 tools, the server covers a comprehensive Kanboard domain but feels heavy. While each tool is justified for full lifecycle management, the count exceeds typical MCP server scope (3-15 tools), making it borderline overwhelming.
Completeness4/5
The tool surface is very comprehensive, covering CRUD for projects, tasks, subtasks, comments, columns, swimlanes, users, and files, plus batch and movement operations. Minor gaps exist, such as missing list_comments or get_subtask by id, but the core workflows are well supported.
Average 4.4/5 across 39 of 39 tools scored. Lowest: 3.6/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description only states the basic operation and return format. It does not disclose behavioral traits such as read-only nature, authorization needs, rate limits, or error handling, leaving the agent underinformed.
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 two sentences that front-load the core purpose and efficiently cover parameters and return format, with no redundant or extraneous information.
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 simple list operation with optional parameters, the description covers the key points: what it does, how to specify the project, and what the return structure is. It lacks detailed error handling or behavior when no project is found, but is largely sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already covers both parameters with descriptions. The description adds the note about configuring .kanboard.yaml but largely reinforces what the schema states, providing minimal additional meaning beyond the baseline.
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 'List all columns (board stages) for a Kanboard project,' using a specific verb and resource, and it distinguishes this from sibling tools like create_column, delete_column, and update_column.
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 clear context on how to specify the project (via project_id, project_identifier, or config file) but does not explicitly guide when to use this tool versus other column-related siblings, nor does it mention 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.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It covers project resolution from explicit IDs or .kanboard.yaml, and states the return value. However, it does not disclose potential side effects (e.g., duplicate name handling), authorization requirements, or failure modes. This is adequate but not comprehensive.
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 two sentences, front-loaded with the core purpose, then provides sibling guidance and return value. Every word serves a purpose with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the 4 parameters and no output schema, the description covers project resolution and return value. However, it lacks information on error handling, idempotency, or ordering constraints. The absence of annotations increases the need for such context, so completeness is adequate but not thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the schema already documents all parameters with descriptions. The tool description adds no significant extra meaning beyond what the schema provides (e.g., project resolution is already in schema as 'overrides .kanboard.yaml'). Baseline score of 3 is appropriate.
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 ('Add a swimlane') and the resource ('to a Kanboard project'). It specifies project resolution from explicit IDs or config file, and distinguishes from sibling tools by naming related operations (move_swimlane, update_swimlane, delete_swimlane).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for when to use this tool (adding a swimlane) and explicitly names sibling tools for reordering, renaming, and removing, guiding the agent to appropriate alternatives. It does not list explicit exclusion criteria but the context is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries the burden. It mentions the return value { column_id } on success but does not disclose behavioral traits like idempotency or duplicate handling. Adequate but lacking depth.
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?
Three sentences, front-loaded with purpose, then resolution, then related tools and return value. No wasted words, efficient and clear.
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?
Covers purpose, project resolution, return value, and sibling differentiation. Lacks details on error behavior or validation, but sufficient for a creation tool with good schema coverage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline 3. Description adds minimal value beyond schema, only clarifying project resolution. No enrichment for other parameters.
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?
Description clearly states 'Add a column to a Kanboard project board' with a specific verb and resource. It also mentions related tools (move_column, update_column, delete_column) to distinguish from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explains project resolution from explicit IDs or config file, and lists alternative tools for reordering, renaming, and deleting. Could be improved by explicitly stating when not to use this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description shoulders the transparency burden. It states the basic behavior (create) and return type, but omits details like error states (e.g., missing parent task), side effects, or authentication requirements.
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 three sentences, each serving a clear purpose: introduce the action, define status values, reference sibling tools, and state the return type. No unnecessary words.
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 creation tool with 6 parameters (2 required) and no output schema, the description covers the core behavior, status meanings, related tools, and return format. Missing error handling details but still adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% parameter descriptions, so the baseline is 3. The description reiterates status values (0=todo, etc.) already present in the schema, adding minimal extra value beyond consolidating information.
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 explicitly states 'Create a subtask under an existing Kanboard task,' specifying the resource and action. It contrasts with sibling tools list_subtasks and update_subtask, ensuring clear differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides guidance on when to use alternatives (list_subtasks, update_subtask), but does not mention prerequisites like the existence of the parent task, which would enhance usability.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral transparency burden. It discloses the state-changing action (reopening) and the return format on success, but does not mention potential failure modes, authorization requirements, or constraints like whether the task must exist.
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 two sentences with no wasted words. It front-loads the action and effect in the first sentence and adds inverse relation and return format in the second.
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 simple tool with one parameter and no output schema, the description covers the core action, inverse, and return format. It is largely complete, though it omits error conditions or edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already provides 100% coverage with a clear description for the task_id parameter. The tool description does not add substantive meaning beyond what the schema provides, so baseline 3 applies.
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 tool reopens a closed Kanboard task and restores it to the active board. It explicitly identifies itself as the inverse of close_task, distinguishing it from sibling tools like delete_task.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implicitly indicates the tool is for closed tasks by stating 'Reopen a closed (inactive) Kanboard task' and notes it is the inverse of close_task, providing context. However, it lacks explicit when-not-to-use guidance or alternatives beyond close_task.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries the burden. Discloses return value shape and re-iterates required constraints. Lacks side effects or permission details, but sufficient for a creation tool.
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?
Three sentences, no fluff. Purpose, optional params, post-creation actions, and return value each get a sentence. Highly efficient.
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?
Covers creation and subsequent steps. Return value is specified. No output schema, but shape is simple. Adequate for the tool's complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline 3. Description adds grouping of optional params and mentions the name length constraint already in schema. Marginal added value.
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?
Clearly states 'Create a new Kanboard project.' with specific verb and resource. Distinct from sibling tools that create other entities.

Three sentences, front-loaded with core purpose, followed by resolution logic and sibling pointers. No wasted words or redundant information.
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 tool with 16 parameters and no output schema, the description covers critical aspects: project resolution, fallback defaults, and return value. It could be more complete by explaining conflict resolution (e.g., if both project_id and project_identifier provided) or error cases.
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?
Schema coverage is 100% (baseline 3). The description adds value by explaining project resolution from explicit IDs or config file and noting fallback defaults for column_id, owner_id, category_id, swimlane_id, which goes beyond the schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5

Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context for when to use alternatives (batch creation, moving tasks) and explains fallback behavior for optional fields. It does not explicitly state when not to use the tool, but the guidance is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description discloses that the operation is destructive and irreversible, and specifies the return format. This is sufficient for a simple deletion action, though additional details (e.g., authorization needs) could enhance transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: a single sentence that conveys purpose, behavioral traits, and return format without any unnecessary words.
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 delete tool with no output schema, the description covers the action, destructive nature, confirm requirement, and return structure. It lacks mention of prerequisites like task existence, but this is implicitly understood.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and both parameters are well-described in the schema. The description reinforces the 'confirm' requirement but adds no new semantic information beyond the schema.

Provides explicit when-to-use for each scope, notes admin token requirement for 'all', and documents required parameters for 'project' scope. Also mentions unsupported API method to guide users away from invalid requests.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description explains resolution logic for omitted parameters (swimlane_id, project) and states return value on success. Lacks error handling details but covers main behavioral traits.
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?
Two efficient sentences covering purpose, parameter constraints, alternative tool, and return value. No redundant information.
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?
The description adequately covers usage, parameter constraints, and return format. While it doesn't mention all sibling tools, the key distinction from update_task is made, and resolution logic is explained.
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?
Schema coverage is 100%, but description adds valuable context: case-insensitive column_name resolution, fallback behavior for swimlane and project, and mutual exclusivity of column_id/column_name.
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?
Description clearly states 'Move a Kanboard task to a different column, position, or swimlane' with specific verb and resource, and distinguishes from sibling 'update_task' by noting it only changes board placement, not other attributes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states 'this is the only way to change a task's board placement', provides guidance on parameter mutual exclusivity ('Provide exactly one of column_id or column_name'), and advises using 'update_task' for other attribute changes.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It explains partial update ('only fields you pass are changed'), validation before write (invalid call modifies nothing), and the return format on success. It doesn't detail error responses for non-existent swimlanes or other failures, but is otherwise transparent.
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 concise and well-structured: first sentence states purpose, second covers behavior, third provides validation rule, fourth gives alternatives and return format. Every sentence serves a clear function 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?
Given the tool's complexity (3 parameters, update operation, no output schema), the description covers most needed aspects: purpose, usage guidance, behavior, param semantics, and alternatives. It lacks explicit mention of error responses for non-validation errors (e.g., when swimlane doesn't exist), leaving a minor gap.
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?
Schema coverage is 100%, so base is 3. The description adds value by explaining the partial update behavior and the validation rule requiring at least one additional field, which goes beyond the schema's field descriptions. This helps the agent understand parameter interplay.
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 ('Update an existing Kanboard swimlane'), the resource ('swimlane'), and specifies that it is a partial update. It also distinguishes from sibling tools like move_swimlane and delete_swimlane, leaving no ambiguity about its purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly tells when not to use this tool (not for reordering, use move_swimlane; otherwise use delete_swimlane) and provides a critical condition: at least one field besides swimlane_id must be provided, else VALIDATION_ERROR. This guidance helps the agent decide correctly.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses partial update behavior, validation before write, requirement for at least one field besides task_id, and return format. No annotations present, so description carries full burden and does it well.
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?
Four focused sentences with front-loaded key information; no redundancy or wasted words.
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?
Covers partial update, validation, required condition, error case, and return format. Lacks mention of other potential errors (e.g., not found), but still comprehensive for a complex tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. Description adds context about partial update and validation rules beyond schema, compensating well.
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?
Clearly states it updates task attributes (partial update) and distinguishes from move_task_position which handles column/swimlane changes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (updating attributes) and when not to (column/swimlane changes), but does not list all alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully discloses the behavioral impact: sets task inactive, leaves the board, is reversible, and returns a specific response. It clarifies that this is NOT a delete, which is critical for an agent to understand the 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at three sentences with no extraneous words. It front-loads the primary action and immediately adds key differentiators and return info, making it efficient and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite having no output schema and no annotations, the description covers all necessary aspects: what the tool does, its reversible nature, alternatives, and the success response format. For a simple one-parameter tool, this is complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already provides a clear description for the single parameter 'task_id' ('Id of the task to close (required).') with 100% coverage. The description adds no additional semantic information about the parameter beyond what the schema offers, so it meets the baseline but does not exceed it.
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 'Close (archive) an active Kanboard task.' It specifies the verb ('Close') and the resource ('active Kanboard task'), and distinguishes from the sibling tools reopen_task and delete_task, making its 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 Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly tells when to use this tool (to archive a task) and when not to (for permanent deletion, use delete_task). It also mentions that reopening is possible via reopen_task, providing clear guidance on alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description fully covers non-atomic behavior, partial failure, fallback defaults, and return structure, leaving no hidden behaviors.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
