Server Quality Checklist

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

Latest release: v0.1.0
Disambiguation4/5
Most tools have clearly distinct purposes, such as creating, updating, deleting, or retrieving specific entities. However, slight overlap exists between 'planka_find_and_get_card' and 'planka_get_card', and 'planka_get_labels' may be redundant with workspace data, but descriptions clarify intent.
Naming Consistency4/5
The vast majority follow a consistent 'planka_verb_noun' pattern (e.g., planka_create_card, planka_delete_label). A few outliers like 'planka_board_status' and 'planka_card_ready_check' break the pattern, and 'planka_next_card' uses an adjective as verb, but overall naming is predictable.
Tool Count4/5
38 tools is on the higher end but appropriate for a full-featured project management server covering boards, lists, cards, labels, custom fields, tasks, comments, and members. Each tool serves a specific action, and while a few could be merged, the count is reasonable for the domain.
Completeness3/5
The tool set covers most core operations (CRUD for cards, labels, custom fields, tasks, comments), but lacks board update/delete, list delete, and comment delete. The presence of specialized tools like 'planka_board_status' and 'planka_card_ready_check' indicates attention to workflows, yet gaps remain.
Average 3/5 across 38 of 38 tools scored. Lowest: 1.6/5.

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?
With no annotations, the description should disclose behavioral traits. It only states 'update', implying mutation, but gives no details about idempotency, side effects, permissions, or required state of the field.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence, but it is under-specified rather than concise. It fails to convey necessary information efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and multiple parameters, the description is critically incomplete. It does not explain return values, side effects, or how to use the parameters.
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%, so the description must compensate for parameter meaning. It does not mention any parameters, leaving the agent to rely solely on the schema, which lacks descriptions (per context).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Update a custom field' provides a verb+resource but is generic and does not distinguish from sibling tools like planka_create_custom_field or planka_set_custom_field_value. It lacks specificity about what aspects of a custom field can be updated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus other custom field tools (e.g., create, delete, set value). The agent has no context for decision-making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description omits that the tool updates position in addition to completion status. No disclosure of side effects, permissions, or behavior beyond basic update.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence is concise, but lacks necessary detail; could be expanded for clarity.
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?
Incomplete given no output schema and the tool's actual functionality; fails to mention position updates or provide sufficient behavioral info.
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?
Description adds no value beyond schema property descriptions; it even contradicts by implying only completion status, ignoring position.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description claims only updating completion status, but schema includes position parameter. Does not accurately represent the tool's full functionality.
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?
No guidance on when to use this tool versus alternatives like planka_update_card or other task-related tools. Lacks context for appropriate use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description only mentions creation of a board with lists and labels, but provides no details on destructive nature, permissions, or side effects. With no annotations, this is insufficient for an agent to understand the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is one concise sentence, but it lacks structure and critical information. It is not front-loaded with the most important details.
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 has three parameters and no output schema or annotations, the description is incomplete. It does not describe return values, prerequisites, or the implications of creating a board with canonical lists.
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?
Although the input schema includes descriptions for parameters, the context signal indicates 0% schema description coverage. The tool description does not explain the parameters like board_type or project_name, failing to add meaning beyond the schema.
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 clearly states 'Create a new board' which is a specific verb+resource combination. However, 'with canonical lists and lifecycle labels' is vague and does not differentiate from sibling tools like planka_create_list or planka_create_label.
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?
No guidance is provided on when to use this tool versus alternatives such as planka_create_list. There is no mention of prerequisites or context for board creation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It does not disclose any behavioral traits like immediate availability, permissions, or side effects. Minimal disclosure beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no fluff, but it is too concise, lacking necessary context. Every sentence should earn its place, and this one could be expanded to add value without becoming verbose.
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 has multiple parameters (name, position, show_on_front_of_card), no output schema, and no annotations, the description is incomplete. It does not explain what a custom field is or the implications of parameters like show_on_front_of_card.
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% per context, but the description adds no value beyond the schema. It does not explain parameters like custom_field_group_id, name, position, or show_on_front_of_card. The description fails to compensate for the lack of schema descriptions.
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 clearly states the action (create) and resource (custom field inside a custom field group). However, it does not differentiate from sibling tools like planka_update_custom_field or planka_delete_custom_field, lacking specificity about the scope.
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?
No guidance on when to use this tool versus alternatives, such as updating an existing custom field. No prerequisites or context about when creation is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description lacks behavioral details such as irreversibility, side effects on cards or other entities, or authorization requirements. With no annotations, the description should carry this burden but does not.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence, which is concise but lacks substance. It is front-loaded but could be expanded with relevant context without losing conciseness.
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 single-parameter deletion tool with no output schema or annotations, the description is incomplete. It does not explain prerequisites, the effect on related data, or the expected outcome, leaving the agent with insufficient information.
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%, so the description must compensate for parameter meaning. It does not add any context beyond what the schema already provides for custom_field_id, such as format, constraints, or usage tips.
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 clearly states 'Delete a custom field,' which is a specific verb-resource pair. However, it does not differentiate from sibling tools like planka_delete_custom_field_group or planka_delete_custom_field_value, which have similar naming and purpose.
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?
No guidance is provided on when to use this tool over alternatives. For example, it does not explain when deletion is appropriate versus using update, or any prerequisites like ensuring no cards depend on the custom field.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits (e.g., read-only vs. destructive, pagination, return format). The description only says 'find and get', implying a read operation, but nothing about limits, scope, or side effects. Insufficient for safe agent usage.
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?
Extremely concise single sentence. No wasted words, but missing critical details that could be added without length penalty. Front-loads the core action.
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 no output schema and no annotations, the description fails to cover expected behavior like return format, whether multiple results are returned, or error conditions. For a search tool, this is incomplete.
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 description adds no new meaning beyond the input schema. The schema already describes 'query' as searching names/descriptions and 'board_id' as board filter. Baseline 3 is appropriate given schema descriptions are present, even though context indicates 0% coverage (likely an error).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Find and get card details by search query', which indicates the main action (search cards) but does not differentiate from sibling tools like planka_get_card (get by ID) or planka_list_cards (list all). It lacks specificity about what 'get card details' entails.
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?
No guidance on when to use this tool versus alternatives. For example, it doesn't mention that this is for searching by query, while planka_get_card is for direct ID lookup. No when-not-to-use or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden for behavioral disclosure. It merely states the tool lists cards with filtering and pagination, but does not disclose any behavioral traits such as ordering, caching, rate limits, or whether it returns only non-archived cards.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (one sentence) but lacks structure and substance. It could be expanded to include key details without becoming verbose.
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 number of parameters (9) and no output schema, the description is incomplete. It does not explain filtering options, pagination behavior, output formats, or detail levels, leaving the agent to rely solely on the schema.
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%, so the description must compensate but fails to add any meaning beyond parameter names. While the schema itself has good descriptions for each parameter, the tool description does not explain how the parameters interact or their relevance.
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 clearly states the action ('List') and resource ('cards'), and mentions filtering and pagination. However, it does not differentiate this tool from sibling tools like 'planka_get_card' or 'planka_find_and_get_card', which also involve listing or retrieving cards.
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?
No guidance is provided on when to use this tool versus alternatives. The description lacks any context about prerequisites, typical use cases, or scenarios where this tool is preferred over others.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description indicates an update (mutation) but provides no details on side effects, permissions, reversibility, or atomicity. With no annotations, the burden falls entirely on the description, which falls short.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence, which is efficient but lacks structure. While it is not verbose, it sacrifices informativeness for brevity, earning a middle score.
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 4 parameters, no output schema, and no annotations, the description is insufficient for an agent to understand the tool's full behavior. It does not cover return values, constraints, or typical usage patterns, making it incomplete for the complexity level.
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?
Despite the schema having parameter descriptions, the tool description itself only mentions 'name and/or position', omitting the required 'custom_field_group_id' and optional 'response_format'. With 0% schema description coverage (as per context), the description should compensate but fails to explain all parameters clearly.
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 clearly states it updates a custom field group's name and/or position, using a specific verb and resource. However, it does not differentiate from sibling tools like create or delete custom field group, which is a minor gap.
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?
No guidance is provided on when to use this tool versus alternatives (e.g., create_custom_field_group, delete_custom_field_group). There is no mention of prerequisites, context, or when not to use it, leaving the agent without decision support.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must carry full burden. It only says 'mechanically validate' without explaining side effects, validation results, or permissions needed. Minimal behavioral disclosure.
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?
Single sentence with no wasted words, but extreme brevity sacrifices necessary detail. Appropriate for very simple tools but borderline here.
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?
Tool has one required parameter and no output schema. Description is minimally adequate for a simple validation check, but lacks details on return values or error conditions.
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%, meaning the schema descriptions are insufficient. The tool description adds no parameter meaning beyond the parameter names and types, leaving the agent uninformed about how to use parameters correctly.
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?
Description states 'validate a card against the card-schema readiness rules', clearly indicating a validation action on a card. However, it does not distinguish from sibling tools like planka_get_card or planka_find_and_get_card, which are retrieval-oriented.
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?
No guidance on when to use this tool versus alternatives. No context about prerequisites or when validation is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description only says 'Create a list', implying mutation but lacking disclosure of behavioral traits such as permissions, idempotency, 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence, front-loaded with the core action. However, it lacks structure or details that could be included without bloat.
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 no output schema and no annotations, the description should provide context about return values, effects, or constraints. It fails to do so, leaving gaps for a 3-parameter tool.
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?
The description does not add any meaning beyond the input schema, which already has descriptions for name, board_id, and position. Schema coverage is 0% meaning the description adds no value.
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 'Create a list on a board' clearly states the action and resource, distinguishing it from sibling create tools like create_board or create_card.
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?
No guidance on when to use this tool versus alternatives like planka_update_list or planka_create_card. No exclusions or prerequisites mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description implies a write operation ('Create') but provides no additional behavioral context such as authorization requirements, side effects, or limitations. With no annotations present, the burden is on the description, which falls short.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single efficient sentence that is front-loaded with the action and object. There is no fluff or redundancy.
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 simple tool (two required string params, no output schema), the description lacks context about what a task list is, how it relates to cards, or any behavior beyond creation. The parameter descriptions in the schema help, but the tool description itself is incomplete.
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 tool description adds no meaning beyond the input schema. Although the schema itself includes descriptions for 'name' and 'card_id', the coverage metric shows 0% because the description does not reference or elaborate on parameters. The description fails to compensate for low schema_description_coverage.
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 'Create a named task list on a card' clearly states the action and resource. It is specific enough to distinguish from siblings like 'planka_add_task' (adds a task to a list) or 'planka_create_list' (creates a list on a board), though it does not explicitly compare them.
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?
No usage guidance is provided. The description does not specify when to use this tool versus alternatives, nor does it mention prerequisites like the need for an existing card.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states the action without mentioning that deletion is irreversible, requires specific permissions, or may cascade effects. This is insufficient for an AI agent to understand the consequences.
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 very concise—a single sentence. It is front-loaded with the key information. However, it could benefit from additional context without losing 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 destructive operation with one parameter and no output schema, the description lacks completeness. It does not mention irreversibility, error conditions, or expected outcomes, leaving the agent underinformed.
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 only parameter, card_id, is described in the input schema itself. The tool description adds no further meaning, but since the schema already defines its purpose, the baseline score of 3 is appropriate despite 0% schema description coverage indicated in context.
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 'Delete a card from Planka' clearly states the action (delete) and the resource (card), making the purpose unambiguous. However, it does not differentiate from sibling tools like planka_remove_card_label, which also remove something from a card, but the distinct action is clear.
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?
No guidance is provided on when to use this tool versus alternatives such as planka_update_card or planka_find_and_get_card. There is no mention of prerequisites, constraints, or conditions for safe usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states 'Add a task to a card.' without mentioning side effects, authentication requirements, or how it handles missing parameters (e.g., card_id fallback behavior is only in the schema). This is minimal and insufficient for safe invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, which is concise but lacks structure. It does not front-load critical information such as required prerequisites or typical usage patterns. Every sentence should earn its place; this one is too vague to be fully helpful.
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?
Considering the complexity of the tool (5 parameters, fallback logic, no output schema, no annotations), the description is far too minimal. It does not explain how parameters relate, what happens when card_id vs task_list_id is used, or what the expected return value is. The description is incomplete for an AI agent to use reliably.
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 detailed descriptions for each parameter (e.g., 'Fallback: resolve a task list from this card when task_list_id is not provided'). The tool description adds no additional meaning beyond the schema. With high schema coverage, a baseline score of 3 is appropriate.
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 'Add a task to a card.' uses a specific verb and resource, clearly indicating the action. It distinguishes from siblings like planka_create_task_list (creates a list, not a task) and planka_update_task (modifies, not adds). However, it could be more precise about the relationship between tasks, cards, and task lists.
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?
No guidance on when to use this tool versus alternatives such as planka_create_task_list or planka_update_task. No context about prerequisites (e.g., card must exist) or when to avoid using it. The description does not help the agent choose correctly.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavioral traits. It only states 'Update an existing card's properties' without mentioning side effects, idempotency, or partial update behavior. Minimal transparency 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with key information (verb + resource). No wasted words. Efficiently communicates the core purpose.
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 has 7 parameters and no output schema, the description is too sparse. It does not explain partial update behavior, optional fields, or what happens with defaults. Incomplete for effective use.
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% as the description adds no parameter info. The schema itself has descriptions, but the tool description does not compensate for low coverage. It does not add meaning beyond the input schema.
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?
Description clearly states verb 'Update' and resource 'existing card's properties', distinguishing it from siblings like planka_create_card and planka_delete_card. However, it lacks specificity about which properties can be updated.
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?
No guidance on when to use this tool vs alternatives (e.g., planka_add_card_label for adding labels). Does not mention prerequisites or scenarios where other tools are preferred.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description lacks information on side effects, permissions, error handling, or what happens upon success. Minimal behavioral disclosure beyond the action itself.
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?
Single sentence, no redundancy. Concise but could be slightly expanded for clarity. However, conciseness is good.
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?
Missing information about return values, error conditions, and behavior despite having many sibling tools. Incomplete for a creation tool with no output schema or annotations.
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 description does not add meaning beyond the input schema, which already contains detailed descriptions for each parameter. Schema coverage is high, so no penalty for missing param info in description.
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 clearly states the action ('create') and the resource ('a new card in a specified list'), but does not distinguish from sibling tools like planka_update_card or planka_add_card_label.
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?
No guidance on when to use this tool versus alternatives. Does not mention prerequisites, exclusions, or context-specific usage hints.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility for behavioral disclosure. It states 'Delete' but does not mention any side effects, irreversibility, required permissions, or return behavior. This is insufficient for a destructive action.
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, brief sentence that efficiently conveys the core function with no extraneous words. It is well-structured and front-loaded.
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?
The description is too sparse for a delete tool with no output schema, no annotations, and many sibling tools. It does not cover prerequisites, effects, or output, leaving the agent underinformed for correct invocation.
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 only parameter, task_id, is described in the input schema as 'ID of the task to delete', which is clear. The tool description adds no extra context (e.g., where to obtain the ID). Despite the context indicating 0% schema coverage, the schema actually provides a description, so the description's contribution is minimal but acceptable.
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 'Delete a task from a card' clearly states the action (delete) and the target (task from a card). It effectively distinguishes this tool from sibling tools like planka_add_task and planka_update_task, though it could be more specific about the context (e.g., task as a checklist item).
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?
No guidance is provided on when to use this tool vs alternatives such as planka_delete_card or planka_delete_label. The description lacks explicit context for selection, assuming the agent knows to use it only for deleting a task from a card.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
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 action. It does not disclose whether the tool is read-only, how comments are ordered, or any side effects. The limit parameter implies pagination but not explained.
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 concise sentence with no wasted words. It could be slightly more informative, but it is front-loaded with the essential action.
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?
With 4 parameters, no output schema, and no annotations, the description is insufficient. It omits details about default behavior, filtering, pagination (limit, prefix), and output format options, leaving the agent without enough context to use the tool effectively.
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 contains descriptions for each parameter (e.g., card_id, limit, prefix_filter, response_format), so the description does not add extra meaning. Baseline score of 3 is appropriate as the schema already documents parameters.
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?
Description clearly states 'List comments on a card' with a specific verb and resource. It distinguishes from sibling tools like planka_add_comment (write) and planka_get_card (different resource), though no explicit differentiation is given.
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?
No guidance on when to use this tool versus alternatives such as filtering via prefix_filter or handling pagination. The description does not mention alternatives or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and description lacks behavioral details. Does not indicate whether the tool is read-only or if it modifies state (e.g., marks card as in progress). 'Full execution context' is vague and undefined.
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?
Single sentence with no clutter. Every word serves a purpose, though 'full execution context' could be more precise.
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?
No output schema exists, and the description does not explain the return value or what 'execution context' means. An agent cannot infer the structure of the response or how to handle the output.
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% according to context, and the tool description adds no explanations for parameters beyond what the schema provides. The description does not help an agent understand board_id, list_name, or response_format semantics.
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 verb 'Get', resource 'top card of a list', and default list name 'TODO'. It distinguishes from siblings like planka_get_card and planka_list_cards by specifying 'top' and 'default list'.

Usage Guidelines2/5
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. Does not mention exclusions, prerequisites, or why one would choose this over planka_find_and_get_card or planka_list_cards.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits. It only says 'set', omitting details like whether it overwrites, behavior on non-existent fields, or required permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% (context signal), so the description must compensate. It only names 'name or color' without explaining the color palette or the requirement for label_id. The schema descriptions provide some detail, but the tool description adds little 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?
The description clearly states 'Update a label's name or color.' It specifies the verb (update) and resource (label), and distinguishes from sibling tools like create_label and delete_label.
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. It is implied that it is for modifying existing labels, but no when-not-to-use or context is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. The description only states 'add' without disclosing side effects (e.g., whether adding a duplicate label is ignored or throws error), authentication needs, or idempotency. Minimal behavioral context.
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?
Single sentence, front-loaded with action. No unnecessary words. Could add a bit more context without being verbose.
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 tool, the description and schema cover basic usage. Missing information about error handling, prerequisites (label must exist, card must exist), and return value. Sibling tools provide some context.
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 tool description adds no parameter information beyond what the input schema already provides (both parameters have clear descriptions in the schema). With 0% schema description coverage in the tool description, it fails to compensate, but the schema descriptions themselves are sufficient.
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 'Add a label to a card' clearly states the action (add) and resources (label and card), distinguishing it from sibling tools like planka_remove_card_label (remove) and planka_create_label (create).
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?
No explicit guidance on when to use this tool versus alternatives. The label_id parameter description hints at using planka_get_workspace, but no direct comparison to other tools is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must convey behavioral traits. It states 'bulk-move' but omits details about destructiveness, idempotency, prerequisites, or what happens to existing card order. The schema hints at ordering behavior via keep_order, but the description does not clarify.
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, clear sentence with no filler. It front-loads the verb and resource, making it efficient for an agent to parse.
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 complexity of a bulk-move operation, the description lacks details about return formats, error handling, maximum card count (only in schema), and ordering behavior. With no output schema or annotations, the description is insufficient for an agent to fully understand the tool's behavior.
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 contains descriptions for all parameters, though context signals erroneously report 0% coverage. The tool description adds no additional semantic value beyond what the schema provides, so a 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 ('bulk-move cards') and the target ('to a target list'), with a specific context ('for kanban ceremonies'). It distinguishes from sibling tools that perform other operations like create, delete, or update.
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 during kanban ceremonies but does not specify when to use this tool versus alternatives (e.g., update_card for single moves). No explicit exclusions or when-not-to-use guidance are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description only states the action ('rename and/or reorder') but does not disclose behavioral traits like side effects, required permissions, error handling, or idempotency. With no annotations provided, the description fails to compensate for missing behavioral 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, front-loaded sentence with no unnecessary words. Every word contributes to understanding the tool's core function.
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 update tool with three parameters and no output schema, the description is sufficiently complete. It directly states the supported operations (rename and reorder) and implies optional parameters. However, lacking annotations or additional behavioral details prevents a perfect score.
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 description summarizes the parameters (name and position) via 'rename and/or reorder,' but the schema already provides clear parameter descriptions. With 0% schema description coverage (as per context), the description adds minimal value; however, it correctly maps to the key 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?
The description uses a specific verb ('rename and/or reorder') with a clear resource ('board list'), directly indicating the tool's function. It distinguishes itself from sibling tools like planka_create_list (create) and planka_update_card (update card), 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 Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance provided on when to use this tool versus alternatives (e.g., creating a new list or updating a card). The description lacks context on prerequisites, such as needing the list_id or the intended workflow.
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. Description adds the behavioral trait 'idempotent by name' which is useful for understanding re-invocation safety. Lacks details on permissions, side effects, or error handling.
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?
Single sentence with no redundancy, efficiently conveying the core action and idempotency. Front-loaded with key information.
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?
With no annotations, no output schema, and minimal parameter coverage, the description lacks context for proper use. Missing usage scenarios, duplicate handling, and differentiation from numerous siblings. Incomplete for a creation tool.
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% (schema description is generic), and the tool description does not elaborate on parameters beyond the schema. The schema itself contains adequate descriptions for name, color, and board_id, but the tool description adds no extra semantic 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?
Description explicitly states 'Create a label on a board' with the idempotency trait. Distinguishes from siblings like planka_update_label and planka_delete_label by focusing on creation and idempotency.
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?
No explicit when-to-use or alternatives are provided. The idempotency hint is useful but does not advise on when to prefer this over other label-related tools. Basic guidance is implicit but limited.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'Get detailed information' without mentioning any behavioral traits such as read-only nature, authorization requirements, rate limits, or what constitutes 'detailed'. This is minimal transparency for a retrieval 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?
The description is a single, front-loaded sentence with no extraneous words. Every part is essential.
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 no output schema, the description does not explain the return format or content. While the schema provides parameter details, for a retrieval tool, some indication of what 'detailed information' includes would improve completeness. The description 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?
The input schema already describes parameters (card_id, response_format, response_context) with detailed descriptions. The tool description adds no extra meaning beyond the schema. With schema description coverage effectively not 0% (despite context signal), baseline 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 'Get detailed information about a specific card' clearly states the verb (Get) and resource (detailed information about a specific card). It distinguishes from sibling tools like planka_list_cards (which lists cards) and planka_find_and_get_card (which finds and then gets).
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 when specific card details are needed, but no explicit when-to-use, when-not-to-use, or alternatives are provided. With siblings like planka_find_and_get_card and planka_list_cards, guidance on when to choose this tool over others is lacking.
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 the full burden of behavioral disclosure. It correctly indicates a read-only operation ('Read'), but it does not mention any potential errors (e.g., resource not found), authentication requirements, or additional behavioral traits beyond reading. The return format is hinted but not explicitly stated, leaving some ambiguity.
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, clear sentence that conveys the core purpose without unnecessary words. However, it could be slightly more informative by mentioning the output format options or typical usage context, without violating conciseness.
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 low complexity (1 parameter, no nested objects, no output schema), the description is minimally adequate. It explains what is retrieved (fields and values) but lacks details on the structure of the response, error handling, or any pagination. For a simple read tool, it is sufficient but not thorough.
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?
Despite the context signal indicating 0% schema description coverage, the actual input schema includes descriptions for both parameters (custom_field_group_id and response_format). However, the tool description adds no extra meaning beyond what the schema already provides. It does not explain how to construct the ID or when to use the response_format parameter, leaving the agent to rely solely on the schema.
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 'Read' and clearly identifies the resource as a 'custom field group.' It also specifies that the output includes 'its fields and values,' setting clear expectations. This distinguishes it from sibling tools like planka_create_custom_field_group or planka_get_card.
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 the tool should be used when you need to retrieve a custom field group with its details, but it does not explicitly state when to prefer this tool over alternatives (e.g., planka_get_card for cards) or provide usage context like prerequisites (e.g., needing the group ID). However, for a simple read operation, the usage is self-evident.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden for behavioral disclosure. It mentions 'fast targeted refresh' but does not disclose what happens if the board is not found, whether the operation is read-only, or any rate limits or authentication requirements. The description adds minimal behavioral context beyond the schema.
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, concise sentence with no unnecessary words or fluff. It efficiently communicates the core purpose and a key benefit.
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 lack of output schema and annotations, the description is incomplete. It does not describe the return format (e.g., a list of labels or objects), what happens on error, or any state changes. The single parameter and simple functionality are not fully covered, leaving important gaps for an AI agent.
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?
The schema description coverage is reported as 0%, meaning the description must compensate. However, the description does not mention the board_id parameter or provide any additional meaning beyond the schema's basic definition. It does not explain where to find the board ID or how it relates to the refresh behavior.
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 verb 'Get' and the resource 'all labels on a board', and adds a performance benefit (fast targeted refresh) that distinguishes it from sibling tools that create, update, or delete labels. This provides a specific and distinct purpose.
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 implies when to use this tool ('fast targeted refresh without full workspace re-fetch'), suggesting efficiency for label retrieval without re-fetching the entire workspace. However, it does not explicitly state when not to use or compare to alternatives like planka_get_workspace.
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 behavioral disclosure burden. It correctly indicates a read operation (get), but does not specify behavior on authentication failure, side effects, or rate limits. For a simple identity fetch, it is minimally adequate.
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 that immediately conveys the tool's purpose and output. It is front-loaded with the important information and contains no unnecessary words.
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?
For a simple read tool with one optional parameter and no output schema, the description is complete. It states what the tool returns (id, username, role) and implies the target identity (authenticated user). No additional context is needed.
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?
The tool has one parameter 'response_format' with a default and enum, and the schema provides a description. However, the tool description itself adds no extra meaning beyond the schema; it does not mention the parameter at all. Given 0% schema description coverage, the description should compensate but fails to do so.
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 retrieves the authenticated user's identity, listing the specific fields (id, username, role). It uses a specific verb 'get' and resource 'authenticated user identity', and distinguishes well from sibling tools which focus on other entities like cards, boards, labels, etc.
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 the tool is to be used when the agent needs the current user's identity, but there is no explicit guidance on when to use this versus other tools. No alternatives or exclusions are mentioned, though the use case is straightforward.
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 carries full burden. It details the output components (per-list counts, ages, blocked cards, etc.), which is valuable. However, it does not explicitly state that the tool is read-only or mention any side effects, which 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that packs essential information without wasting words. It is front-loaded 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?
Given the complexity of the tool (multiple report components), the description covers all key aspects. It lacks explicit mention of return format or edge cases, but the output format parameter addresses part of that. Overall 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 input schema already provides descriptions for all parameters (board_id, response_format, done_window_days), so coverage is high. The tool description adds context about what the output includes but does not significantly enhance parameter understanding beyond schema.
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 it provides a board status report with specific components like per-list counts, in-progress ages, blocked cards, etc. This verb+resource combination is precise and distinguishes it from siblings like planka_list_cards or planka_get_card.
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 when to use it (for a board status summary), but does not explicitly state when not to use it or provide alternative tool names. No prerequisites or exclusions are mentioned.
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 provided, the description carries full responsibility for behavioral transparency. It honestly describes that the tool returns a 'complete workspace structure' and that using 'board_name' yields a 'fraction of the full dump,' implying a read-only operation. No contradictions exist, though it could mention auth needs or rate limits.
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: two sentences that front-load the purpose and immediately provide actionable guidance on parameter usage. Every sentence adds value without 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 complexity of the tool (returning workspace structure) and the absence of an output schema, the description is somewhat vague about the exact return format or structure. It lists components but does not detail nested hierarchies or data format, which could leave the agent uncertain about the response.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already provides parameter descriptions with high coverage. The description adds further value by explaining scoping trade-offs (e.g., 'cheaper than a full dump' for board_name) and explicitly linking parameters to the behavior. This goes beyond the schema's minimal definitions.
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's purpose: 'Get complete workspace structure (projects, boards, lists, labels, users).' It uses a specific verb ('Get') and resource ('workspace structure'), and distinguishes itself from sibling tools like 'planka_get_card' or 'planka_get_labels' by offering a comprehensive dump with optional scoping.
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 good usage guidance: 'Pass project_name or board_name to scope the response' and explicitly notes that 'board_name returns a fraction of the full dump.' This helps the agent decide when to use parameters. However, it does not explicitly compare to alternative sibling tools for specific queries, leaving some room for interpretation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
