These do not move a task. The ClickUp v2 API has no move-between-lists endpoint. Verified against the live API 2026-08-12:
POST /list/{list}/task/{task}adds a secondary location and leaves the home list unchanged, while alist_idinPUT /task/{id}returns HTTP 200 and is silently ignored. To genuinely move a task and keep its custom ID and history, use the ClickUp web UI (right-click -> Move). Multi-list membership also requires the paid Tasks-in-Multiple-Lists feature.

Available Tools
37 toolsclickup_add_dependencyB
Add a dependency between tasks (waiting_on or blocking)
| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | The task to add the dependency to | |
| depends_on | No | Task ID this task is waiting on | |
| dependency_of | No | Task ID that this task blocks |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavior. It fails to explain mutation consequences, whether dependencies are directional, what happens on duplicate, or required permissions. The difference between depends_on and dependency_of is not elaborated.
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 concise sentence with no redundant words, but it could benefit from slight structuring to improve readability.
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, and the need to clarify mutual exclusivity of depends_on/dependency_of, the description is insufficient. It does not cover return value or edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and description adds no extra meaning beyond the parameter names and schema descriptions. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (add), the resource (dependency between tasks), and specifies the two dependency types (waiting_on or blocking), distinguishing it from sibling tools like clickup_add_tag_to_task or clickup_add_task_link.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., clickup_delete_dependency), no when-not-to-use conditions, and no mention of prerequisites or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_add_tag_to_taskC
Add a tag to a task
| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | ClickUp task ID | |
| tag_name | Yes | Tag name to add |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states 'Add', implying mutation, but does not discuss idempotency, duplicate behavior, permissions, or side effects. 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence, front-loading the core purpose without extraneous words. 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?
Although the tool is simple, the description lacks context on whether the tag must already exist, what happens if the tag is already added, or the response format. Without output schema, this gap is notable.
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% coverage with descriptions for both parameters (task_id and tag_name). The description adds no additional parameter meaning beyond the schema, so a baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Add a tag to a task' clearly states the action and target resource. It specifies the verb 'Add' and the resource 'tag to a task', which is distinct from sibling tools like removing tags or creating space tags.
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?
There is no guidance on when to use this tool versus alternatives like clickup_create_space_tag or clickup_remove_tag_from_task. The description does not mention prerequisites (e.g., tag must exist) or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_add_task_linkC
Link two tasks together
| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | First task ID | |
| links_to | Yes | Second task ID to link to |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full burden for behavioral disclosure. It only states 'link two tasks together' without explaining implications such as directionality, reversibility, permissions, or side effects. Minimal 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 concise sentence with no waste. However, it may be too brief given the need to differentiate from siblings and explain behavior. Still, it is efficient.
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 tool with no output schema or annotations, the description is too sparse. It does not explain the nature of the link, how to remove it, or what happens upon linking. Incomplete for an agent to use confidently.
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?
Parameter descriptions in schema are fully documented (100% coverage). The description adds no additional meaning beyond the schema, so baseline score of 3 applies.
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 'Link two tasks together' clearly states the verb and resource. However, it does not distinguish from the sibling 'clickup_add_dependency', which might also link tasks in a different way. Thus it is clear but lacks 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?
No usage guidance is provided. There is no information on when to use this tool versus alternatives like 'clickup_add_dependency' or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_create_checklistC
Create a checklist on a task
| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | ClickUp task ID | |
| name | Yes | Checklist 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 only states 'Create a checklist on a task'. It does not disclose what happens upon creation (e.g., overwrites existing, returns ID, permissions needed).
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, clear sentence with no unnecessary words. It could be expanded slightly for more context, but it is appropriately concise for its simplicity.
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 creation tool with 2 parameters and no output schema, the description is minimally adequate. It lacks details on side effects or usage context but covers the core action. Slight improvement possible.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both parameters. The description adds no additional meaning beyond the schema, which already clarifies that task_id and name are required. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool creates a checklist on a task (verb+resource). However, it does not differentiate from sibling tools like clickup_edit_checklist or clickup_delete_checklist, which could cause confusion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like clickup_create_checklist_item or clickup_edit_checklist. No context about prerequisites or conditions for creation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_create_checklist_itemB
Add an item to a checklist
| Name | Required | Description | Default |
|---|---|---|---|
| checklist_id | Yes | Checklist ID | |
| name | Yes | Item name | |
| assignee | No | User ID to assign |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description does not disclose behavioral traits such as idempotency, duplicate handling, or permission requirements. Only states 'Add' with no further context.
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?
Extremely concise (one sentence) but lacks important details. It is not verbose but could be more informative without being longer.
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?
No output schema, and description does not explain return values or side effects. For a creation tool, missing behavioral context like response format or prerequisites.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so schema already describes parameters. Description adds no new meaning beyond what is in the parameter descriptions.
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 action and object: 'Add an item to a checklist'. This distinguishes it from siblings like 'create_checklist' or 'edit_checklist_item'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. Could be confused with editing an item or adding dependencies. No exclusion criteria mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_create_commentC
Add a comment to a task
| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | ClickUp task ID | |
| comment_text | Yes | Comment text | |
| assignee | No | User ID to assign with this comment | |
| notify_all | No | Notify all assignees (default true) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, and the description lacks behavioral disclosures such as side effects, authentication needs, or error behavior. Only the schema hints at notification via the notify_all parameter.
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 concise sentence. For a straightforward tool, this is efficient, though it could benefit from more context.
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?
With no annotations and no output schema, the description is too brief. It fails to provide behavioral transparency or usage context, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for all 4 parameters. The description adds no additional meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Add a comment to a task', which is a specific verb and resource. However, it does not distinguish from sibling tools like clickup_create_reply or clickup_update_comment.
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 usage guidelines provided. The description does not indicate when to use this tool over alternatives, nor does it mention any prerequisites or contexts.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_create_listA

| status | No | Status name to use as default |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must bear the full burden. It only states that the tool creates a list but does not disclose behavioral details like permissions, return value, side effects, or error behavior. For a mutation tool, 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, clear sentence with no redundancy. It directly conveys the tool's purpose and location options, meeting conciseness goals.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with 7 parameters and no output schema. The description covers the main use cases but lacks details such as the mutual exclusivity of folder_id and space_id, return behavior, or prerequisites. It is marginally adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with each parameter already described. The description adds no new meaning beyond reinforcing the folder vs. folderless context, but that is already evident from the parameter descriptions. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (create a new list) and specifies the two contexts: in a folder or folderless in a space. This distinguishes it from siblings like clickup_create_task or clickup_create_checklist.
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 when to use this tool (to create a list) and the two possible locations (folder or space). However, it does not provide explicit guidance on when not to use it or alternatives, such as clickup_get_lists for retrieval.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_create_replyB
Add a threaded reply to a comment
| Name | Required | Description | Default |
|---|---|---|---|
| comment_id | Yes | Comment ID | |
| comment_text | Yes | Reply text |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses no behavioral traits like idempotence, error handling, permission requirements, or side effects beyond the basic action.
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?
Single sentence of 5 words, perfectly front-loaded and concise with no fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given low tool complexity (2 params, no output schema), the description is too minimal. It lacks usage context and behavioral details, making it harder for an agent to select correctly among sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with basic descriptions. The description adds no additional meaning beyond what is already in the schema (e.g., comment_id and comment_text are self-explanatory). Baseline 3 applies.
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 uses specific verb 'Add' and resource 'threaded reply to a comment', clearly distinguishing it from sibling tools like clickup_create_comment (top-level comment) and clickup_get_replies (retrieval).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. Lacks context about prerequisites (e.g., comment must exist) or when not to use (e.g., if you need to update a reply instead).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_create_space_tagB

| tag_bg | No | Background color hex (e.g. '#000000') |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Minimal behavioral disclosure. Lacks details on idempotency, duplicate handling, limits, or whether creation overwrites existing tags. No annotations to compensate.
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?
Single sentence is concise and front-loaded, but slightly too terse; could be organized to include usage context or return info.
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?
No output schema, and description does not explain return value or behavior. Missing context for a create tool, especially given sibling tools exist.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with basic descriptions; description adds no extra meaning beyond what schema already provides. Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (create) and the resource (a new tag in a space), distinguishing it from sibling tools like edit or delete.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives (e.g., edit_space_tag or delete_space_tag). No mention of prerequisites such as needing the space_id or naming constraints.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It only states the basic function without mentioning side effects, idempotency, permissions, rate limits, or error handling. This is insufficient for informed agent decision-making.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise and front-loaded, conveying the essential purpose in just six words. Every word is necessary and contributes directly to understanding. No wasted text.
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 (16 parameters, no annotations, no output schema), the description is severely incomplete. It omits return values, error scenarios, behavioral nuances, and integration context with sibling tools. A more comprehensive description 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?
The input schema has 100% description coverage, so the schema itself documents all parameter meanings. The description adds no additional semantic value or contextual hints beyond the schema. Score remains at baseline 3.
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 task in a list' clearly states the action (create), the resource (task), and the scope (in a list). It effectively distinguishes this from sibling tools like clickup_update_task or clickup_delete_task.
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 usage guidelines are provided. The description does not mention when to use this tool versus alternatives (e.g., clickup_update_task), nor does it specify prerequisites or contexts that might influence selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_get_list_membersB
Get members with access to a specific list
| Name | Required | Description | Default |
|---|---|---|---|
| list_id | Yes | ClickUp list ID |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits (e.g., return format, required permissions, rate limits). It simply states the purpose without any additional behavioral context, such as whether results are paginated or what fields are returned.
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 concise sentence with no extraneous words. It is front-loaded and efficient.
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 has no output schema and no annotations, the description should at least hint at what is returned (e.g., member names, roles). It does not, leaving the agent uninformed about the output format.
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 single parameter 'list_id' is fully described in the schema as 'ClickUp list ID', and the description does not add further meaning. Schema coverage is 100%, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves members with access to a specific list. It uses a specific verb-resource pair ('Get members') and distinguishes itself from siblings like clickup_get_workspace_members (broader scope) and clickup_get_list (different resource).
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 (e.g., clickup_get_workspace_members for workspace-level members). There are no explicit when-to-use or when-not-to-use instructions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, permissions required, 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two sentences, front-loading the purpose and providing key usage instruction without wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the schema covers all parameters and no output schema is provided, the description is adequate but could mention default filtering (e.g., archived excluded) or expected response characteristics.
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 description adds value beyond the schema by clarifying the mutual exclusivity of folder_id and space_id and distinguishing between folder and space contexts, despite 100% 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 ('Get lists') and the context (in a folder or folderless in a space), distinguishing it from related tools like 'get_list' or 'create_list'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides the condition to provide either folder_id or space_id, but does not explicitly guide when to use this tool versus alternatives like 'get_list' for a single list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_get_repliesA
Get threaded replies to a comment
| Name | Required | Description | Default |
|---|---|---|---|
| comment_id | Yes | Comment ID |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior. It states 'Get' (a read operation) but does not mention error handling, pagination, ordering of replies, or any side effects. Minimal behavioral info.
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?
One short sentence that is front-loaded and contains no redundant information. Every word is necessary.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema, no annotations), the description is minimally adequate. However, it could mention the return format (list of replies?) or constraints for completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% coverage for the single parameter 'comment_id' with description 'Comment ID'. The description adds no extra meaning beyond the schema, meeting the baseline expectation.
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 threaded replies to a comment' clearly identifies the action ('Get') and the resource ('threaded replies to a comment'), distinguishing it from sibling tools like clickup_get_comments (which gets top-level comments) and clickup_create_reply.
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 explicit guidance on when to use this tool vs alternatives like clickup_get_comments or clickup_create_reply. The description implies usage but lacks context (e.g., prerequisite comment ID from get_comments).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_get_spacesC
List all spaces in a workspace
| Name | Required | Description | Default |
|---|---|---|---|
| team_id | Yes | ClickUp workspace/team ID | |
| archived | No | Include archived spaces (default false) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should reveal behavioral traits like pagination, response structure, or permissions. It only states a basic read operation. The default behavior for the 'archived' parameter (false) is implied but not explained.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (one sentence) but omits important contextual details. It is not wordy, but could be more informative without becoming too lengthy.
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?
No output schema and no mention of response format, pagination, or filtering (beyond the archived param). The description fails to fully prepare an AI agent for what the tool returns or how it behaves in edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and both parameters have clear descriptions. The tool description adds no additional meaning beyond the schema, so a baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (List) and resource (spaces) but does not differentiate from similar sibling tools like clickup_get_folders or clickup_get_lists. It lacks context on what a 'space' uniquely represents in ClickUp's hierarchy.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. It does not mention that workspaces are required, or that archived spaces can be included via the param. Siblings with similar purposes are not distinguished.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_get_space_tagsA
List all tags in a space
| Name | Required | Description | Default |
|---|---|---|---|
| space_id | Yes | ClickUp space ID |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior. It states it lists tags, but does not mention return format, pagination, or any constraints. Minimal transparency for a read-only list operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of five words, with no unnecessary information. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple list tool with one parameter and no output schema, the description is adequate. It could mention what is returned (e.g., 'returns tag names') but is complete enough for its simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a description for space_id. The description does not add meaning beyond the schema, but the schema already adequately defines the parameter.
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 to list all tags within a space, specifying the verb 'list' and the resource 'tags' with scope 'in a space'. It distinguishes from sibling tools like create, delete, edit, add, remove tags.
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 when needing to view all tags in a space, distinct from write operations. No explicit when-not or alternatives are provided, but sibling names make the distinction clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
clickup_get_taskC
Get a task by its ID

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It states the tool searches 'entire workspace', implying broad scope unless filtered, which is useful. However, it omits details about pagination, sorting, default behavior, or result limits.
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 concise sentence, front-loaded with the core action. However, it is too brief and sacrifices necessary detail, making it only adequate in structure.
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 has 19 parameters and no output schema, the description is severely incomplete. It does not explain return format, pagination behavior, filtering scope, or how filters combine. An agent would lack essential 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?
Schema coverage is only 32%, so the description should compensate by explaining key parameters, but it does not mention any. The description adds no semantic value beyond the schema fields, leaving many parameters (e.g., page, order_by) undocumented.
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 'Search tasks across an entire workspace' clearly indicates the verb and resource, but it does not distinguish this tool from sibling 'clickup_get_tasks', which may also retrieve tasks. The scope 'entire workspace' is helpful but lacks 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?
No guidance is provided on when to use this tool versus alternatives like 'clickup_get_tasks' or 'clickup_get_task'. The description does not specify prerequisites, context, or scenarios where searching is preferred over listing.

clickup_set_custom_fieldA
Set a custom field value on a task (update_task cannot do this)
| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | ClickUp task ID | |
| field_id | Yes | Custom field ID | |
| value | Yes | Custom field value (type depends on field type) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It only states the basic operation, omitting important details such as idempotency, error handling, permissions, rate limits, or side effects. This is insufficient for an agent to understand the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence with a parenthetical note, front-loading the key information. It is efficient but could be slightly more structured to include additional context without extra length.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (3 parameters, no output schema, no annotations), the description lacks completeness. It does not cover return behavior, error handling, prerequisites, or what happens after setting the field, leaving significant gaps for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage with descriptions for each parameter, so the baseline is 3. The description adds marginal value by reinforcing the purpose but does not provide additional semantic detail beyond what the schema already offers.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool sets a custom field value on a task and explicitly distinguishes it from the sibling tool 'update_task', which cannot perform this action. This provides a specific verb and resource, making the purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when needing to set a custom field that update_task cannot handle, but does not provide explicit guidance on when not to use it or alternative scenarios. It offers clear context without exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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 four parameters and no output schema, the description lacks completeness. It does not explain whether multiple operations can be combined, what the response looks like, or how to handle errors. The agent may struggle to use the tool 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?
Schema description coverage is 100%, so the schema already documents parameters. The description adds context by grouping allowed operations (text edit and resolve/unresolve), but does not add new semantic detail beyond what the schema provides.
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 'edit' and the resource 'comment', and distinguishes between two primary actions: editing text or toggling resolved status. This specificity differentiates it from creation or deletion tools among siblings.
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 clickup_create_comment or clickup_get_comments. There is no mention of prerequisites or contexts where this tool is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| archived | No | Archive/unarchive the task |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description must disclose behavioral traits. Only mentions assignee format. Missing details: partial vs full update, required permissions, idempotency, error scenarios, or side effects. For a tool with 14 parameters, 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?
Two sentences: first states purpose, second gives a key parameter guideline. No redundancy or filler. Efficient and well-structured.
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?
Despite high parameter count and nested objects, description omits return values, update semantics, and error handling. Incomplete for a tool of this complexity, especially with no output 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 coverage is high (86%), so baseline is 3. Description adds value by clarifying assignees use add/rem arrays, which prevents misuse. However, other parameters are not elaborated beyond schema descriptions.
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?
Description clearly states 'Update a task', identifying verb and resource. Though brief, it distinguishes from siblings like create_task or delete_task by focusing on update. The note about assignees adds context but does not further differentiate from other update operations.
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 explicit guidance on when to use this tool vs alternatives. Sibling tools like set_custom_field or create_comment exist but are not mentioned. The description does not specify conditions for use, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description implies a read-only operation but does not explicitly state side-effect safety or authentication requirements. Given no annotations, it minimally covers 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?
A single sentence that is front-loaded and contains no redundant words, efficiently conveying the tool's purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no parameters and no output schema, the description fully covers what the tool returns and its scope, making it complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, so the schema coverage is 100% vacuously. The description does not need to add parameter meaning, earning a baseline of 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves current user info and a list of workspaces with members, which is specific and distinguishes it from sibling tools that perform CRUD operations.
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 explicit when-to-use or when-not-to-use guidance is provided, but the purpose is straightforward and obvious from the description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Each tool targets a distinct resource and action (e.g., task, checklist, tag, comment, list, space, dependency). The descriptions clearly differentiate between similar operations like add_dependency vs add_task_link, and create_checklist vs create_checklist_item. There is no ambiguity in tool purposes.
All tools follow the 'clickup_verb_noun' pattern in snake_case. Verbs are consistently used (add, create, delete, edit, get, remove, update, set, search). Even compound nouns like 'add_tag_to_task' maintain the same structure. No mixing of conventions.
With 37 tools, the server covers a broad range of ClickUp operations. While this is above the typical 3-15 tool guideline, the complexity of ClickUp warrants many endpoints. Each tool seems necessary for core workflows, so it is slightly over but still reasonable.
The tool set covers tasks, checklists, comments, lists, tags, and spaces comprehensively, but notable gaps exist: there is no update_list, create_folder, delete_folder, or any space management (create/update/delete spaces). These missing operations could force agents into incomplete workflows.
