Server Quality Checklist

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

Latest release: v1.0.0
Disambiguation5/5
Each tool serves a clearly distinct purpose. Checklist operations are separated into add, list, update, delete, and clear. Issue operations are similarly granular. Even similar tools like search_issues and search_issues_scroll are differentiated by scroll capability, leaving no ambiguity.
Naming Consistency5/5
All tools follow a consistent verb_noun pattern using snake_case (e.g., add_checklist_item, list_components, update_issue). The naming is predictable and uniform across the entire set.
Tool Count5/5
With 21 tools, the server covers the typical lifecycle of an issue tracker: CRUD for issues and checklists, search, linking, comments, sprints, components, validation, and Miro sync. The count is well-scoped for the domain without being too sparse or excessive.
Completeness4/5
The tool surface covers most essential operations: issue creation, retrieval, update, checklist management, linking, commenting, validation, and sprint/component listing. Minor gaps exist, such as no tool for deleting an issue or removing a link, but these are not critical dead ends.
Average 3.9/5 across 21 of 21 tools scored. Lowest: 3.2/5.

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 present, so the description carries full burden. It only states the action and a formatting rule, missing important behavioral traits such as side effects, permissions, or response format.
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 sentences with no wasted words. Front-loaded purpose stated first, followed by a critical usage guideline. Efficient and well-structured.
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 3 parameters, no output schema, and no annotations, the description is far too brief. Missing critical context: validation rules, error cases, maximum text length, and behavior of the 'mention' field.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not provide any additional meaning for the parameters (issue_key, text, mention). The agent must rely solely on parameter names.
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 'Adds a comment to an issue' with a specific verb and resource, making it distinct from sibling tools like create_issue or add_checklist_item. No ambiguity.
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?
Provides explicit guidance on how to format comments when posting on behalf of the agent ('[AI Agent]:'). Lacks when-not-to-use or alternatives, but no other comment tool exists.
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 that the tool 'Removes' an item, implying a destructive operation, but fails to mention any side effects, permissions required, error handling (e.g., if item not found), or whether the operation is idempotent. This minimal disclosure is 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description consists of two short sentences, no superfluous words, and immediately delivers the core purpose and a critical prerequisite. Every word earns its place.
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 deletion tool with no output schema and no annotations, the description should cover return behavior, side effects, and error scenarios. It only states the action and a prerequisite, omitting whether deletion is reversible, what happens on success/failure, or any post-condition. This leaves too many gaps for an agent to operate safely.
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?
With 0% schema description coverage, the description must compensate. It adds limited meaning by noting that item_id comes from list_checklist_items, but does not explain issue_key's purpose or format, nor provide any constraints or examples for either parameter. The schema itself gives only type and required status, so the description adds marginal 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 the action ('Removes a single checklist item') and the resource ('from an issue'). It distinguishes this tool from siblings like add_checklist_item (adds), clear_issue_checklist (removes all), and update_checklist_item (modifies). The verb is specific and the scope (single item) is explicitly noted.
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 a prerequisite: 'Requires the checklist item id from list_checklist_items,' which guides the agent to first fetch IDs. However, it does not explicitly state when to use this tool versus siblings (e.g., for multiple deletions use clear_issue_checklist) or mention alternative approaches. The context is clear but lacks exclusionary guidance.
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 exist, so the description carries full burden. It states that it returns specific fields and uses optional filters, but does not disclose whether the operation is read-only, pagination behavior beyond a limit parameter, sorting defaults, 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at three sentences, front-loaded with purpose and returned fields, and includes practical usage guidance. No redundant 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?
Given 7 parameters with no schema descriptions and no output schema, the description lacks details on filter behavior (exact match vs partial), default sorting, pagination offset, error handling, and what happens with no results. Incomplete for a filtering 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 coverage is 0%, so the description must compensate. It mentions 'optional filters' but does not explain the individual parameters (queue, status, assignee, etc.), their expected formats, or how multiple filters combine.
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 lists Tracker issues with optional filters, providing a specific verb and resource. It also specifies returned fields. However, it does not differentiate from sibling search tools like search_issues, which also list issues with filters.
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 explicitly says when to use this tool ('when user asks to show, find, list, or check issues') and advises calling it before update_issue or add_comment when lacking an issue key. It does not provide explicit when-not-to-use scenarios 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 are provided, so the description bears full responsibility for behavioral disclosure. It describes what the tool does and its parameters but does not mention side effects, required permissions, error handling, or constraints (e.g., what happens if issue_key is invalid). This is insufficient 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?
The description is a single, concise sentence that front-loads the action and key details. Every part adds information; there is no redundancy or filler.
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 tool has 6 parameters, no output schema, and no annotations, the description is adequate but not complete. It explains the parameters' purpose but omits return value, error states, and potential constraints beyond the schema.
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 0%, so the description must compensate. It explains that 'text' is required, 'checked' is optional boolean, 'assignee' is login or id, and 'deadline_date' is ISO string with deadlineType defaulting to 'date'. However, it does not elaborate on 'issue_key' or 'deadline_type' enum values, leaving some gaps.
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 'Adds' and the resource 'one checklist row to an issue', which is a specific, distinct action. It effectively differentiates from sibling tools like 'delete_checklist_item' or 'clear_issue_checklist' by specifying addition.
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 (adding a checklist row) but does not explicitly state when not to use or list alternatives. It lacks guidance on prerequisites or scenarios where other tools might be more 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; description bears full burden. Only states creation and key return, lacking details on side effects, permissions, error behavior, or constraints. Insufficient disclosure for a mutation tool with 12 parameters.
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 sentences, no unnecessary words. Purpose and usage hint are front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite 12 parameters and no output schema, the description is sparse. Lacks details on return format, parameter dependencies, or typical use cases. Incomplete for a complex 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?
With 0% schema description coverage, description adds minimal meaning. Identifies queue and summary as critical but does not explain other 10 parameters like type, assignee, or sprint. Falls short of compensating for missing schema descriptions.
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 'Creates a new Tracker issue' with a specific verb and resource. Distinguished from siblings like update_issue and search_issues by focusing on creation.
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?
Provides explicit usage guidance: 'Always confirm queue and summary before creating,' implying the need for user verification. Notes the return value for immediate reference. Does not mention when not to use or compare with alternatives.
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 fully disclose behavioral traits. It only states it creates a link, but omits whether links can be overwritten, if there are access restrictions, or any side effects (e.g., does updating an issue's link affect other relations?).
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 sentences, no fluff. Efficiently states purpose and usage in a compact form.
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 tool with 3 required params and no output schema, the description covers the basic functionality but lacks return value info and parameter clarifications. It's 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 has 0% description coverage. Description mentions 'two issues' implying from_key and to_key, and link_type via 'typed link'. However, it doesn't explain the meaning of enum values (e.g., 'relates' vs 'blocks'), so the agent may misuse the type.
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 the tool creates a typed link between issues, and specifies common use cases (connecting work, blockers, parent-child). This distinguishes it from siblings like create_issue, update_issue, etc.
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?
Description explicitly says when to use (connect related work, mark blockers, set hierarchies), but doesn't mention when not to use or alternatives. Still clear enough for basic guidance.
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 burden. It implies a read-only operation but does not explicitly state safety, auth needs, or potential performance impact for large hierarchies. The description 'returns' is a minimal behavioral clue.
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 concise sentences: first defines function, second provides usage guidance. No unnecessary words, front-loaded with key information.
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?
No output schema; description describes hierarchy but lacks details on structure (e.g., tree vs list) or handling of large hierarchies. Could be more complete for a tool with no output 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 coverage is 0%, meaning description adds no extra meaning to parameters. Although epic_key is implied by context, the description does not explain it or include_closed (default false). The schema provides names/types but description should compensate for the lack of coverage.
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 the tool returns the full child hierarchy under an epic, specifying stories, tasks, and subtasks. It distinguishes itself from sibling tools like get_issue or search_issues by focusing on hierarchical breakdown.
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: 'when the user wants to see the full breakdown of a feature or initiative.' It does not provide alternatives or conditions where not to use, but the use case is clear.
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 does not disclose behavioral traits such as read-only nature, authentication requirements, or rate limits. Since this is a listing operation, it is likely read-only, but this is not confirmed.
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 with two sentences. The first clearly states the purpose, and the second provides usage guidance. No unnecessary words or repetition.
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 covers the main purpose and provides usage guidance. However, it lacks details about the output format (e.g., what fields are returned), which would be helpful given the absence of an output schema.
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 has one required parameter (issue_key) with 0% coverage in description. The description does not add any meaning beyond the schema, such as format or constraints. However, the parameter is simple and common, so the 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 'Lists all checklist items on an issue,' specifying the verb 'list' and the resource 'checklist items on an issue.' It also distinguishes itself from siblings like add_checklist_item, delete_checklist_item, and update_checklist_item by mentioning the need to obtain item IDs before those operations.
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 explicitly advises using this tool (or get_issue with include_checklist) to obtain item IDs before update_checklist_item or delete_checklist_item. This provides clear context for when to use the tool, though it does not explicitly state 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?
No annotations exist, so description carries full burden. It discloses exact-match requirement but omits other behaviors like authentication needs, error responses, or pagination. Adequate for a simple list 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?
Two sentences, front-loaded with action, no redundant words. Highly concise and structured.
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 simplicity (1 parameter, no output schema), the description covers purpose and usage. Lacks details on output format or errors, but is reasonably complete for its low complexity.
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%. Description mentions 'in a queue' but does not elaborate on the 'queue' parameter format, allowed values, or optionality. Adds minimal value beyond stating parameter presence.
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 'Lists all components in a queue' with a specific verb and resource. It also provides a validation use case, but does not explicitly differentiate from sibling tools like list_issues or list_checklist_items.
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 says 'Use this to validate component names before creating or updating issues,' providing clear when and why. Also notes 'Component names must match exactly' as a behavioral constraint.
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?
Discloses ordering by start date and status field, but no annotations are present. Description does not cover potential side effects, permissions, rate limits, or pagination behavior.
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 sentences: first explains what the tool does, second gives usage examples. No wasted words, front-loaded with purpose.
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?
Covers purpose and usage adequately for a simple list tool, but lacks details on parameter semantics and return format. No output schema provided, so description could have helped more.
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 only parameter 'queue' is not described in the schema (0% coverage) and the description only says 'for a queue' without clarifying whether it expects an ID or name, or what format is expected.
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 it lists sprints for a queue, ordered by start date with status, and gives specific use cases (find current sprint ID, resolve sprint name). Distinguishes from sibling tools as no other sprint-related tools exist.
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?
Provides explicit use cases ('Use this to find the current sprint ID or to resolve a sprint name'), but does not mention when not to use it or alternatives. However, no alternative sprint tools exist among siblings.
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, the description must disclose behavioral traits. It reveals that setting status fails silently and assignee clearing behavior. However, it does not cover idempotency, auth requirements, or rate limits, leaving gaps 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?
The description is two sentences that efficiently convey purpose, key behaviors, and usage notes. It is front-loaded with the main action and avoids unnecessary words.
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?
The description covers the most critical aspects (status transitions and assignee), but with 9 parameters and no output schema, it lacks explanations for many fields. It is moderately complete but not fully comprehensive.
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. It only explains assignee and status parameters; the other 7 parameters (summary, description, components, story_points, parent, priority) receive no additional context beyond 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 clearly states the verb 'Updates fields' and the resource 'existing issue', distinguishing it from siblings like create_issue. It also adds the useful detail that only changed fields need to be provided.
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?
Provides explicit guidance on when to use (updating fields), how to handle assignee (empty string), and explicitly warns against setting status directly. However, it does not explicitly say when to use this tool vs. other update tools like update_checklist_item.
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?
Discloses destructive nature with confirmation requirement. No annotations provided, but description covers basic behavioral trait. Lacks details like permissions or irreversibility.
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 sentences: first conveys purpose, second adds essential warning. No fluff.
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?
Sufficient for a simple delete tool with one parameter. Provides purpose and behavioral hint. Could mention return status or error cases but not critical.
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?
Only parameter 'issue_key' has no description; schema coverage is 0%. Description does not explain its meaning or format, leaving the agent to infer from 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?
Clearly states 'Deletes the entire checklist on an issue (all items at once)', specifying the exact verb and resource. Distinguishes from sibling 'delete_checklist_item' which deletes individual items.
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 warns that it is destructive and requires user confirmation. No mention of when not to use or alternatives, but context implies using for bulk deletion.
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 burden. It implies read-only behavior with 'Returns', but does not explicitly guarantee safety or disclose any side effects, permissions, or rate limits. 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 return action, and every sentence adds value without redundancy. It is appropriately sized and structured.
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?
The description covers basic purpose and usage but lacks details on parameter behavior (e.g., combination logic) and the exact return structure (no output schema provided). For a simple tool with two optional parameters, it is somewhat incomplete.
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?
With 0% schema coverage, the description merely states 'Optional filters narrow the result' without explaining the individual roles of board_id and tracker_key. This is insufficient to compensate for the missing parameter descriptions.
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 it returns the Tracker↔Miro sync map with a specific data structure (board item IDs paired with issue keys). It distinguishes from sibling tools by advising 'Use before two-way sync' and implies a counterpart for updating.
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 provides explicit use cases: finding existing mappings and resolving IDs, and suggests combining with the Miro MCP server. It implicitly contrasts with the update sibling, offering clear guidance on when 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 must convey behavioral traits. It implies a read operation ('Gets') and lists included fields (description, checklist, linked issues). However, it does not explicitly state it is read-only or mention any restrictions (e.g., authentication, rate limits). Suitable but not thorough.
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 two sentences. The first sentence states the core function, and the second provides usage guidance. No extraneous information, front-loaded with purpose.
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 single-issue retrieval tool without output schema, the description adequately covers the main use case and prerequisite. It names key fields returned. However, the lack of explanation for the boolean parameters slightly reduces completeness.
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. It clarifies the `issue_key` parameter with an example, but does not describe `include_comments` or `include_checklist`. These optional booleans are left unexplained, creating a gap for correct invocation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: retrieving full details of a single issue by key. It provides an example key format and distinguishes itself from sibling tools like list_issues. The verb 'Gets' and resource 'full details of a single issue' are specific and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states when to use the tool (need complete picture, have exact key) and recommends an alternative (use list_issues first if key is unknown). This provides clear guidance for selection among sibling tools.
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 required text re-sending and auto-loading behavior, which is valuable. No side effects or error information disclosed, but adequate for a simple update.
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 sentences, front-loaded with action, no unnecessary words. Every sentence adds value.
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 no output schema and no annotations, the description covers key behaviors and optional parameter guidance. Lacks return value information and deadline format details, but is largely complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must compensate. It explains text auto-loading and the conditional use of checked/assignee/deadline, but deadline_type and deadline_date semantics are missing. Only partial coverage of 7 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 clearly states it updates a checklist item, specifies the identifier source (from list_checklist_items), and distinguishes from sibling tools like add/delete.
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?
Provides explicit guidance: pass checked/assignee/deadline only when changing them, and explains text auto-load behavior. Lacks explicit when-not-to-use but sufficient context.
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 does not disclose safety/behavior (e.g., read-only, error handling) beyond YQL usage.
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 sentences plus example, no wasted words, front-loaded with key info.
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 main usage with examples and sibling distinction, but lacks mention of search_issues_scroll and pagination details.
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 0%; description explains query with an example but does not mention limit parameter.
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 searches issues using YQL, distinguishes from list_issues by noting complex filters.
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 says when to use (complex filters) and when to prefer list_issues (simple cases), with an example query.
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, but the description discloses throttling behavior (~200ms delay per post, extra delay every 10 posts) and mentions it returns a violation report. However, it does not describe the return format or the nature of the violation report, which would be helpful.
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 with front-loaded purpose, immediate usage guidelines, and behavioral detail. No redundant information; each sentence serves a distinct purpose.
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?
The description covers key workflow and throttling, but lacks details on the violation report's structure or content. Without an output schema, this gap could hinder an agent's ability to present results to the user 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?
Schema has 0% description coverage, so the description must add meaning. It explains dry_run and post_comments with usage guidelines, but does not clarify the queue or sprint parameters beyond their names. Partial value added but not fully compensating for the schema gap.
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 validates all open issues in a queue against convention.json and returns a violation report. It uses a specific verb-resource combination and distinguishes from sibling tools like validate_issue (single issue) and list_queue_sprints.
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 instructs to run with dry_run=true first and only set post_comments=true after user confirmation. This provides clear when-to-use guidance and a safe workflow, effectively differentiating usage of the boolean parameters.
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?
Describes the scrolling mechanism, return of next_scroll_id, and requirement to pass same query. No annotations exist, so description carries full burden. Lacks details on side effects, rate limits, or authentication needs, but core behavior is covered.
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 sentences, front-loaded with key info, no wasted words. Efficiently conveys purpose and action steps.
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 scroll mechanism and multiple parameters, description covers main aspects. Slightly incomplete on output format (no output schema, but description doesn't mention returned fields), but sufficient for an agent to invoke correctly.
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?
With 0% schema description coverage, description compensates by explaining query (YQL), per_scroll (max 1000), scroll_type (sorted|unsorted), scroll_ttl_millis, and usage pattern for first vs subsequent calls. Adds value beyond schema names.
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 the tool is for scrollable issue search for very large result sets (10k+ matches), distinguishing it from non-scrollable search tools like 'search_issues'.
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?
Provides step-by-step usage: first call with query, subsequent calls with scroll_id and same query. Also warns against incorrect search body. However, it does not explicitly state when not to use this tool (e.g., for smaller result sets) or compare to siblings.
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, but description clearly states it does not post comment, implying read-only. Could be more explicit about read-only nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with purpose, no wasted 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?
Covers purpose, output, behavior, and next steps. Adequate for a simple validation tool with no output schema.
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?
Single simple parameter (issue_key) is self-explanatory, but description doesn't mention it despite 0% schema coverage.
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 checks issue compliance with a convention, describes output. Distinguishes from siblings like add_comment.
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 says not to post comment automatically, suggests using add_comment separately after showing violations.
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 are provided, so the description carries full burden. It discloses serialized writes (concurrency safety), file name, and mode behaviors. However, it does not detail permission requirements, error states, or side effects of write operations.
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 primary purpose, then concurrency note, then mode-specific guidance. No redundant or extra information; every sentence adds value.
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 no output schema, description adequately covers key aspects: file target, two modes, concurrency, and safe usage. It references sibling tool. Lacks error handling or validation details, but overall complete for a write tool of this complexity.
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 has 3 parameters with 0% description coverage. The description compensates well by explaining entries purpose, mode options with usage guidance (merge by board_id + tracker_key), and board_id_for_replace context. It adds meaning beyond schema names but could elaborate on each property's constraints.
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 updates sync-map.json with new or changed Tracker↔Miro pairs, distinguishing between two modes (upsert and replace_all) and referencing the sibling tool get_miro_sync_map for reading, which sets it apart.
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 explains when to use each mode: upsert for adding one pair at a time, replace_all for full mapping list, advises reading first with get_miro_sync_map for safety, and highlights serialized writes to prevent corruption.
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?
Without annotations, the description adequately discloses the tool's read-only nature and expected output. It implies safe credential verification. However, it does not explicitly state side effects or failure behavior.
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 sentences: first states purpose and output, second provides usage guidance. No wasted words, 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?
Given zero parameters, no nested objects, and no output schema, the description is fully complete. It covers purpose, usage, and expected output.
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?
No parameters exist, so baseline is 4. The description does not add parameter information, but that is unnecessary.
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 verifies API credentials and returns user info (login, display name, email). It distinguishes from sibling tools which deal with issues, checklists, etc., as this is the only authentication-related tool.
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 advises 'Call this first in any new session to confirm the connection is working before calling other tools,' providing perfect guidance on when to use it.
