TDQS
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 states the action ('Add') but doesn't mention required permissions, whether this is a mutation operation, potential side effects, error conditions, or response format. This leaves significant gaps for a tool that modifies data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded with the core functionality.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what happens after attachment addition, error handling, or behavioral context. Given the complexity of modifying issue data, more completeness is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all 5 parameters thoroughly. The description adds no additional parameter information beyond what's in the schema, maintaining the baseline score of 3 for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Add an attachment') and target resource ('to an issue in Linear'), providing specific verb+resource pairing. However, it doesn't differentiate from sibling tools like linear_get_attachments or linear_update_issue, which would require explicit comparison for a score of 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided about when to use this tool versus alternatives. The description doesn't mention prerequisites, exclusions, or comparisons with sibling tools like linear_get_attachments (for viewing) or linear_update_issue (which might also handle attachments).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_add_commentC
Add a comment to a Linear issue
| Name | Required | Description | Default |
|---|---|---|---|
| body | Yes | Comment text (markdown supported) | |
| createAsUser | No | Custom username for the comment creator | |
| displayIconUrl | No | Custom avatar URL for the comment creator | |
| issueId | Yes | Issue ID to comment on |
TDQS
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 states the action ('Add a comment') but doesn't describe what happens—whether this creates a permanent record, requires specific permissions, supports notifications, or has rate limits. For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding the tool's behavior and implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose with zero wasted words. It directly answers 'what does this tool do?' without unnecessary elaboration, making it easy for an agent to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (a mutation operation with 4 parameters), lack of annotations, and no output schema, the description is incomplete. It doesn't address behavioral aspects like permissions, side effects, or response format, leaving the agent with insufficient context to use the tool effectively beyond basic parameter passing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all four parameters (issueId, body, createAsUser, displayIconUrl). The description adds no parameter-specific information beyond what's in the schema, such as examples or constraints. This meets the baseline of 3, as the schema handles the heavy lifting, but the description doesn't enhance parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Add a comment') and target resource ('to a Linear issue'), making the purpose immediately understandable. It distinguishes from siblings like linear_create_issue or linear_update_issue by focusing specifically on commenting. However, it doesn't explicitly differentiate from hypothetical similar tools like linear_update_comment (if it existed), keeping it at 4 rather than 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing issue), exclusions, or comparisons to sibling tools like linear_update_issue (which might also allow commenting). The agent must infer usage from the tool name and schema alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_create_issueC
Create a new Linear issue
| Name | Required | Description | Default |
|---|---|---|---|
| assigneeId | No | User ID to assign the issue to | |
| description | No | Issue description (markdown supported) | |
| priority | No | Priority level (0-4), where 0=no priority, 1=urgent, 4=low | |
| status | No | Initial status name (e.g., 'Todo', 'In Progress') | |
| teamId | Yes | Team ID to create issue in | |
| title | Yes | Issue title |
TDQS
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 but only states the basic action ('Create a new Linear issue'). It doesn't mention authentication requirements, rate limits, what happens when creation fails, whether this is a mutating operation, or any side effects. For a creation tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that gets straight to the point with zero waste. It's appropriately sized for a basic creation operation and front-loads the essential information without unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a creation tool with 6 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what happens after creation, what the tool returns, error conditions, or how it differs from sibling tools. Given the complexity and lack of structured data, the description should provide more complete context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, so the schema already documents all 6 parameters thoroughly. The description adds no additional parameter information beyond what's in the schema. According to the scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Create a new Linear issue' clearly states the verb ('Create') and resource ('Linear issue'), making the purpose immediately understandable. However, it doesn't distinguish this tool from its sibling 'linear_update_issue' or explain what differentiates creation from updating, which prevents a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'linear_update_issue' or 'linear_search_issues'. There's no mention of prerequisites, constraints, or appropriate contexts for creating issues versus other operations, leaving the agent with minimal usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_create_labelC
Create a new label in Linear
| Name | Required | Description | Default |
|---|---|---|---|
| color | No | The color for the label in hex format (e.g. "#FF0000") | |
| description | No | A description for the label | |
| name | Yes | The name of the label | |
| parentId | No | The ID of a parent label to create a nested label | |
| teamId | Yes | The ID of the team to create the label for |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states 'Create' which implies a write/mutation operation, but doesn't mention permission requirements, whether creation is idempotent, error conditions, or what happens on success (e.g., returns label ID). For a mutation tool with zero annotation coverage, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core purpose without unnecessary words. It's appropriately sized for a create operation and front-loaded with the essential action. Every word earns its place with zero waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with 5 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what happens after creation (return value), permission requirements, error handling, or how it differs from sibling update_label. The 100% schema coverage helps with parameters, but behavioral and contextual gaps remain significant.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 5 parameters (color, description, name, parentId, teamId) with clear descriptions. The description adds no parameter information beyond what's in the schema, meeting the baseline of 3 when schema coverage is high. No additional semantics are provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Create') and resource ('new label in Linear'), making the purpose immediately understandable. It distinguishes this from sibling tools like linear_get_labels (read) and linear_update_label (update), though it doesn't explicitly contrast with them. The description is specific but lacks explicit sibling differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing team access), when not to use it (e.g., for updating existing labels), or refer to sibling tools like linear_update_label for modifications. Usage context is implied but not stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_attachmentsC
Get attachments for an issue in Linear
| Name | Required | Description | Default |
|---|---|---|---|
| issueId | Yes | Issue ID to get attachments for |
TDQS
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 states the action but does not cover critical traits like whether this is a read-only operation, potential rate limits, authentication needs, or return format. This leaves significant gaps for a tool that interacts with external data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is front-loaded and appropriately sized, making it easy to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations and output schema, the description is incomplete. It does not address behavioral aspects like safety, performance, or return values, which are crucial for a data retrieval tool. This leaves the agent with insufficient context to use the tool effectively beyond basic invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, with the single parameter 'issueId' fully documented in the schema. The description adds no additional meaning beyond what the schema provides, such as format examples or constraints, so it meets the baseline for high schema coverage without enhancing parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Get') and resource ('attachments for an issue'), making the purpose understandable. However, it does not differentiate from siblings like linear_get_issue_relations or linear_get_labels, which also retrieve issue-related data, so it lacks specificity for distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, such as linear_search_issues for broader queries or linear_get_issue_relations for related data. It implies usage by specifying the resource but offers no explicit context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_issue_relationsC
Get relationships for an issue in Linear
| Name | Required | Description | Default |
|---|---|---|---|
| issueId | Yes | Issue ID to get relationships for | |
| type | No | Filter by relationship type |
TDQS
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 but offers minimal information. It implies a read-only operation ('Get'), but doesn't specify whether it requires authentication, returns paginated results, includes rate limits, or what the output format looks like (e.g., list of related issues with metadata). This leaves significant gaps for a tool that likely interacts with external data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, direct sentence with zero wasted words. It front-loads the core purpose ('Get relationships for an issue') efficiently, making it easy to parse quickly without unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of fetching relational data (likely involving structured outputs) and the absence of both annotations and an output schema, the description is insufficient. It doesn't explain what 'relationships' entail (e.g., linked issues, dependencies), the return format, or error conditions, leaving the agent under-informed for a tool with potential nuanced behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, clearly documenting both parameters ('issueId' and 'type'). The description adds no additional semantic context beyond what the schema provides, such as examples of relationship types or how the filtering works. This meets the baseline for high schema coverage but doesn't enhance understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Get') and resource ('relationships for an issue'), making the purpose immediately understandable. However, it doesn't differentiate this tool from potential sibling tools like 'linear_link_issues' (which might create relationships) or 'linear_get_issue' (which might get issue details without relationships), leaving room for ambiguity about its unique role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an issue ID), exclusions, or how it compares to sibling tools like 'linear_search_issues' or 'linear_get_issue', leaving the agent to infer usage context from the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_labelsB
Get labels from Linear, optionally filtered by team
| Name | Required | Description | Default |
|---|---|---|---|
| includeArchived | No | Whether to include archived labels | |
| limit | No | Maximum number of labels to return | |
| teamId | No | Filter labels by team ID |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states the basic operation. It doesn't disclose behavioral traits like whether this is a read-only operation, if it requires authentication, rate limits, pagination behavior, or what happens when no labels match. The phrase 'Get labels' implies a read operation, but lacks details on permissions, error conditions, 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose. Every word earns its place: 'Get labels from Linear' establishes the action and resource, while 'optionally filtered by team' adds necessary scope information without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read operation with 3 well-documented parameters and no output schema, the description is minimally adequate. However, without annotations or output schema, it should ideally provide more context about the return format (e.g., list of label objects), authentication requirements, or error handling to help the agent use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all three parameters (includeArchived, limit, teamId). The description adds minimal value beyond the schema by mentioning 'optionally filtered by team' which corresponds to the teamId parameter, but doesn't provide additional context about parameter interactions or usage patterns.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Get') and resource ('labels from Linear') with an optional scope ('optionally filtered by team'). It distinguishes from siblings like linear_create_label (create vs get) and linear_get_teams (labels vs teams), though it doesn't explicitly differentiate from other 'get' tools like linear_get_attachments or linear_get_projects.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving labels with optional team filtering, but doesn't provide explicit guidance on when to use this tool versus alternatives like linear_get_teams or linear_get_projects. No exclusions or prerequisites are mentioned, leaving the agent to infer context from the tool name and sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_projectC
Get details about a specific project
| Name | Required | Description | Default |
|---|---|---|---|
| projectId | Yes | Project ID to get details for |
TDQS
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 states it 'gets details,' implying a read-only operation, but doesn't specify what details are returned, potential errors (e.g., invalid project ID), authentication needs, rate limits, or data format. This leaves significant gaps 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with no wasted words. It's front-loaded with the core action and resource, making it easy to scan and understand quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (a read operation with one parameter) and lack of annotations and output schema, the description is incomplete. It doesn't explain what 'details' include, potential response structures, or error handling, leaving the agent with insufficient context for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, with the single parameter 'projectId' clearly documented. The description adds no additional meaning beyond the schema, such as format examples or context about where to obtain the ID. This meets the baseline of 3 since the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Get') and resource ('details about a specific project'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'linear_get_projects' (plural) or 'linear_get_project_issues', which might retrieve related but different data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a project ID), exclusions, or comparisons to siblings like 'linear_get_projects' for listing projects or 'linear_get_project_issues' for project-specific issues.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_project_issuesC
Get issues for a specific project
| Name | Required | Description | Default |
|---|---|---|---|
| includeArchived | No | Include archived issues | |

| projectId | Yes | Project ID to get issues for | |
| status | No | Filter by issue status name |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but discloses minimal behavioral traits. It doesn't mention whether this is a read-only operation, if it requires authentication, rate limits, pagination behavior, or what the return format looks like. 'Get' implies a read operation, but no further details are given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero wasted words. It's appropriately sized for a simple retrieval tool and front-loads the core purpose immediately.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 5 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain what 'issues' are in this context, how results are structured, or provide any behavioral context beyond the basic verb. The agent must rely entirely on the input schema for parameter details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 5 parameters. The description adds no additional meaning beyond implying project-scoped filtering, which is already covered by the 'projectId' parameter in the schema. Baseline 3 is appropriate when schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Get issues for a specific project' clearly states the verb ('Get') and resource ('issues'), but it's vague about scope and doesn't distinguish from siblings like 'linear_get_team_issues' or 'linear_search_issues'. It doesn't specify whether this returns all issues, filtered issues, or paginated results.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'linear_get_team_issues' (for team-scoped issues) or 'linear_search_issues' (for broader searches). The description implies project-specific retrieval but offers no explicit comparison or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_projectsC
Get projects in the organization
| Name | Required | Description | Default |
|---|---|---|---|
| includeArchived | No | Include archived projects | |
| limit | No | Maximum number of projects to return (default: 50) | |
| status | No | Filter by project status (e.g., 'completed', 'in progress') | |
| teamId | No | Filter projects by team ID |
TDQS
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 states a read operation ('Get'), implying it's non-destructive, but doesn't cover critical aspects like authentication requirements, rate limits, pagination behavior (beyond the limit parameter), error handling, or return format. This leaves significant gaps for a tool with 4 parameters and no output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero wasted words. It's front-loaded with the core purpose and appropriately sized for a straightforward list tool, making it easy for an agent to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (4 parameters, no annotations, no output schema), the description is inadequate. It doesn't explain what 'projects' entail in this context, how results are structured, or any behavioral constraints. For a list operation with filtering options, more context on output and usage would be necessary for an agent to use it effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage, so parameters like includeArchived, limit, status, and teamId are well-documented in the schema itself. The description adds no additional parameter semantics beyond implying a list operation, which is already clear from the name and schema. This meets the baseline for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Get projects in the organization' clearly states the verb ('Get') and resource ('projects'), with scope ('in the organization') that distinguishes it from sibling tools like linear_get_project (singular) or linear_get_team_issues. However, it doesn't explicitly differentiate from other list tools like linear_get_teams or linear_get_labels, which follow a similar pattern.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. For example, it doesn't mention when to choose linear_get_projects over linear_get_project_issues or linear_get_team_issues, nor does it specify prerequisites or typical use cases. The agent must infer usage from the name and parameters alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_get_teamB
Get details about a specific team
| Name | Required | Description | Default |
|---|---|---|---|
| teamId | Yes | Team ID to get details for |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It states 'Get details' but doesn't clarify if this is a read-only operation, what permissions are required, error handling, or response format. For a tool with zero annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero waste. It's appropriately sized for a simple lookup tool and front-loaded with the core purpose, making it easy to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (one parameter, no output schema, no annotations), the description is minimally adequate but lacks completeness. It doesn't address behavioral aspects like safety or response format, which are important for an agent to use it correctly despite the simple schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with the single parameter 'teamId' well-documented in the schema. The description doesn't add any meaning beyond what the schema provides (e.g., format examples or constraints), so it meets the baseline for high schema coverage without compensation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so all parameters are documented in the schema. The description adds no additional information about parameters beyond what's in the schema (e.g., it doesn't clarify 'flexible filtering' in relation to the 'query' parameter). This meets the baseline for high schema coverage but doesn't enhance parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Search') and resource ('issues in Linear'), making the purpose immediately understandable. However, it doesn't differentiate this tool from sibling tools like 'linear_get_team_issues' or 'linear_get_project_issues', which appear to be more specific search variants. The term 'flexible filtering' is somewhat vague but still conveys the core functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'linear_get_team_issues' or 'linear_get_project_issues'. It doesn't mention prerequisites, limitations, or typical use cases. The phrase 'flexible filtering' implies broad applicability but offers no concrete usage context.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Update an existing Linear issue' implies a mutation operation but doesn't specify required permissions, whether changes are reversible, rate limits, or what happens to unspecified fields (partial vs. full updates). This leaves significant 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero wasted words. It's appropriately sized for a tool with comprehensive schema documentation and gets straight to the point without unnecessary elaboration.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with 8 parameters, no annotations, and no output schema, the description is insufficient. It doesn't address behavioral aspects like permissions, side effects, or response format. While the schema covers parameters well, the overall context for safe and effective use is incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, providing clear documentation for all 8 parameters. The description adds no parameter-specific information beyond what's in the schema, so it meets the baseline of 3. It doesn't compensate for any gaps since there are none in the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Update') and resource ('an existing Linear issue'), making the purpose immediately understandable. It distinguishes from siblings like linear_create_issue (creation vs. update) and linear_update_label (different resource type). However, it doesn't specify what aspects can be updated, which prevents a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing issue ID), contrast with linear_create_issue for new issues, or specify scenarios where updates are appropriate versus other operations like adding comments or attachments.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
linear_update_labelC
Update an existing label in Linear
| Name | Required | Description | Default |
|---|---|---|---|

| color | No | The new color for the label in hex format (e.g. "#FF0000") | |
| description | No | The new description for the label | |
| labelId | Yes | The ID of the label to update | |
| name | No | The new name for the label | |
| parentId | No | The ID of a new parent label |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states the basic action ('Update an existing label'). It doesn't disclose behavioral traits like required permissions, whether updates are reversible, rate limits, error conditions, or what happens to unspecified fields (partial vs. full updates). For a mutation tool with zero annotation coverage, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with zero wasted words. It's front-loaded with the core action and resource, making it easy to parse quickly. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with no annotations and no output schema, the description is inadequate. It doesn't cover behavioral aspects (permissions, side effects), usage context, or return values. Given the complexity of updating a label with multiple fields and sibling tools available, more completeness is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 6 parameters. The description adds no parameter-specific information beyond what's in the schema (e.g., it doesn't explain relationships between parameters like parentId hierarchy or color format validation). Baseline 3 is appropriate when the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Update') and resource ('an existing label in Linear'), making the purpose unambiguous. It distinguishes from sibling tools like 'linear_create_label' (create vs. update) and 'linear_get_labels' (read vs. update), though it doesn't explicitly mention these distinctions in the description itself.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'linear_create_label' for new labels or 'linear_get_labels' for viewing labels. It also doesn't mention prerequisites (e.g., needing labelId) or contextual constraints, leaving usage entirely implicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 19 tools
Every tool has a clearly distinct purpose targeting specific resources and actions in Linear's domain. For example, linear_get_team_issues retrieves issues for a team, while linear_get_user_issues gets issues assigned to a user, and linear_search_issues allows flexible filtering across all issues. No tools appear to overlap or cause confusion.
All tools follow a consistent 'linear_verb_noun' pattern with snake_case throughout. The verbs are clear and appropriate (e.g., get, create, update, add, link, search), and the nouns specify the target resource (e.g., issue, label, project, team). This predictability makes the tool set easy to navigate.
With 19 tools, this server is well-scoped for managing Linear's core entities like issues, projects, teams, labels, and attachments. Each tool earns its place by covering essential CRUD operations and queries without redundancy, fitting the typical range of 3-15 tools for a comprehensive API integration.
The tool surface provides complete coverage for Linear's domain, including CRUD for issues and labels, attachment and comment management, relationship linking, and queries for projects, teams, and users. There are no obvious gaps; agents can perform full lifecycle operations without dead ends.
