Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds no behavioral context beyond the basic action; e.g., it doesn't note that approval may require password or affect merge readiness.

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 but at the expense of providing necessary context. Lacks front-loading of critical information beyond the verb.

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 absence of output schema and low schema coverage, the description should compensate with behavioral and parameter details. It fails to do so, leaving the agent without essential usage 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?

Schema description coverage is 0% and the description adds no meaning to the four parameters (sha, project_id, approval_password, merge_request_iid). For example, it doesn't explain that approval_password may be required for certain projects.

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 'Approve a merge request' uses a specific verb and resource, clearly differentiating from sibling tools like gitlab_merge_merge_request (which merges) and gitlab_unapprove_merge_request (which removes approval).

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., gitlab_merge_merge_request). No prerequisites, conditions, or exclusions mentioned.

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 does not disclose any behavioral traits beyond what annotations already provide. Annotations indicate non-read-only, non-destructive, non-idempotent, and open-world, but the description adds no context about side effects, authentication, or what 'publish' entails.

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 short (one sentence) and front-loaded, but lacks structure like bullet points or separation of key details. It could be improved while staying concise.

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 bulk operation with no output schema and zero parameter descriptions, the description is too minimal. The agent lacks understanding of what 'publish' means, the required input, and the effect on draft notes.

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 0%, meaning the description does not explain any of the two parameters (project_id, merge_request_iid). The agent receives no help on required vs optional or format, relying solely on 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 'Publish all merge-request draft notes' is clear and specific, using a verb (Publish) and resource (merge-request draft notes). The word 'all' hints at the bulk nature, but it does not explicitly differentiate from the sibling 'gitlab_publish_draft_note' which likely publishes a single draft note.

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 guidelines are provided on when to use this tool versus alternatives. Given siblings like 'gitlab_publish_draft_note' for single publishing and 'gitlab_create_draft_note' for creation, explicit differentiation is absent.

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 only states 'cancel a running pipeline' without elaborating on side effects (e.g., does it stop all jobs? Is the pipeline recoverable?). Annotations confirm it's not read-only, but no additional behavioral context is added.

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 (5 words) but sacrifices completeness. While front-loaded, it lacks essential details about parameters and usage, making it less efficient for correct tool invocation.

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 mutation tool with no output schema and two parameters, the description is insufficient. It should at least mention the required parameter and provide a minimal usage context to ensure the agent can call 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 0%, and the description provides no information about the required 'pipeline_id' or optional 'project_id' parameters. The agent has no guidance on what values to provide or how they affect the operation.

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 (cancel) and the resource (a running pipeline). It easily distinguishes from sibling tools like gitlab_retry_pipeline or gitlab_create_pipeline. However, it does not specify whether it cancels the entire pipeline or individual jobs, which could cause ambiguity.

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 indicate when to use this tool versus alternatives (e.g., retry pipeline, pause job) or mention any prerequisites or consequences.

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?

Annotations indicate readOnlyHint=false and destructiveHint=false, consistent with canceling a job. However, the description does not disclose side effects (e.g., job cannot be restarted) or required permissions, beyond what annotations already provide. No contradiction.

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 a single sentence, but sacrifices necessary context. It is front-loaded but under-specified.

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 description of return values. The tool is simple but lacks details on success/failure behavior or result 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?

Schema description coverage is 0%, and the description provides no explanation of parameters. job_id and project_id are undefined, leaving the agent without guidance on values or usage.

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 'Cancel one running job' clearly states the verb and resource, distinguishing it from sibling tools like gitlab_cancel_pipeline and gitlab_retry_pipeline_job. However, it could be more explicit about it being a GitLab pipeline job.

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 such as gitlab_cancel_pipeline or gitlab_retry_pipeline_job. Missing prerequisites or conditions like 'job must be running'.

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 does not disclose behavioral traits beyond the annotations. It omits details on side effects, data preservation, or any constraints on conversion. The annotations provide some context (not read-only, not destructive), but the description adds no value.

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 wasted words. However, for a complex operation, it may be too terse, lacking necessary 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?

Given the significance of changing a work item type, the description is incomplete. It does not explain the return value, constraints, or impact on related data. No output schema exists to compensate.

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 0%, and the description does not explain any parameters. The meaning of 'iid', 'new_type', and 'project_id' is entirely left to the schema, which lacks 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 'Convert a work item to a different type.' It specifies the verb 'convert' and the resource 'work item', which distinguishes it from sibling tools like update_work_item or move_work_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 versus alternatives. It does not mention prerequisites, when not to use, or scenarios where another tool would be more appropriate.

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?

Annotations already indicate that this is a non-readonly, non-idempotent, non-destructive mutation. The description adds that it creates from an existing ref, but does not disclose side effects (e.g., whether it triggers pipelines, what happens if branch already exists). Beyond annotations, it adds limited behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is an 8-word single sentence that is succinct and front-loaded. Every word is necessary; there is no extraneous content. It is perfectly concise for the tool's 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 mutation tool with no output schema and 3 parameters, the description is too minimal. It does not specify the return value (likely the branch object), error conditions (e.g., branch already exists, invalid ref), or any behavioral details beyond the basic action. The description leaves significant gaps for an agent to safely use this tool.

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 3 parameters (branch, ref, project_id) with 0% schema description coverage. The description mentions 'from an existing ref', hinting at the ref parameter, but does not explain branch (required) or project_id. It adds minimal meaning beyond the schema, failing to compensate for the lack of parameter documentation.

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 branch from an existing ref'). It distinguishes from sibling tools like gitlab_delete_branch or gitlab_list_branches. However, it lacks specificity about what constitutes a valid 'ref' (e.g., branch name, tag, commit SHA), which slightly reduces clarity.

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 implicitly indicates usage when you want to create a branch from an existing reference. There is no explicit guidance on when to use this tool versus alternatives (e.g., gitlab_create_tag for tags), nor any prerequisites (e.g., permissions, uniqueness). The guidance is adequate but minimal.

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 adds no behavioral context beyond what annotations already provide. Annotations indicate it's a write operation (readOnlyHint: false) and not destructive (destructiveHint: false), but the description does not elaborate on side effects, idempotency (which is false), or permissions. The openWorldHint: true suggests broader effects, but that's 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 extremely short (one sentence), but it sacrifices informativeness for brevity. It does not earn its place because it provides minimal value beyond the name. Concise but incomplete.

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 10 parameters and no output schema, the description is woefully incomplete. It does not explain the purpose of parameters, the typical workflow, or expected outcomes. The agent cannot effectively use this tool based on the description alone.

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?

With 0% schema description coverage, the description carries the full burden of explaining parameters. However, it does not mention any of the 10 parameters, including the required 'sha' and 'state'. The enum values for 'state' are not described. The agent gets no help understanding what each parameter means or how to use them.

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 or updates a commit status. It uses a specific verb and resource, and it's distinguishable from sibling tools that don't deal with commit statuses. However, it misses the opportunity to mention that it's typically used in CI/CD pipelines.

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. There is no mention of prerequisites, nor when not to use it. The description only states what it does, not when it's appropriate.

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?

Annotations indicate this is not read-only, not idempotent, and not destructive, but the description adds no behavioral details. It does not explain side effects, permissions needed, or whether the draft note can be edited later. The description carries the burden but fails to provide useful 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?

The description is very short (one sentence), which is concise, but it lacks necessary detail. It is not bloated but fails to convey adequate information for a tool with multiple parameters and siblings.

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 5 parameters, no output schema, and no parameter descriptions, the description is severely incomplete. It does not explain what a draft note is, how to use it, or what the response looks like. The tool's complexity demands much more 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?

Schema description coverage is 0% and the description does not explain any parameter meaning. Parameters like position and resolve_discussion remain opaque. The agent cannot infer correct values from the description alone.

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 states it creates a merge-request draft note, clearly specifying the verb and resource. However, it does not differentiate from sibling tools like gitlab_create_note or gitlab_create_merge_request_discussion_note, leaving ambiguity about what a 'draft note' is compared to other note types.

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 vs alternatives. There is no mention of prerequisites, use cases, or when not to use it. Given the many sibling note creation tools, this is a significant gap.

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?

Annotations indicate it is a write operation (readOnlyHint=false) and not idempotent. The description adds only that it 'creates', but does not disclose potential failure modes (e.g., duplicate name/path), rate limits, or that it is a POST request. Minimal behavioral context beyond annotations.

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, but it is under-specified. It lacks structure (e.g., bullet points for parameters) and omits essential information, making it less useful than a more verbose but complete description.

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?

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 0%, so the description must compensate. Only discussion_id is explained (for discussion replies). Parameters like name, note_id, issue_iid, and project_id are not described. This is insufficient for understanding parameter semantics.

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 explicitly states the action ('Add an emoji reaction') and the target resource ('an issue note'). It distinguishes from sibling tools like gitlab_create_issue_emoji_reaction (which targets issue, not note) and gitlab_create_merge_request_note_emoji_reaction.

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 one usage hint ('Pass discussion_id for discussion replies') but does not offer explicit guidance on when to use this tool versus alternatives (e.g., vs gitlab_create_issue_emoji_reaction). No when-not or exclusion criteria are given.

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?

Annotations indicate it is a write operation (readOnlyHint false), not destructive, and not idempotent. The description adds no further behavioral details such as what happens if the label already exists, permission requirements, or side effects. It does not contradict annotations.

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 (4 words) but at the cost of being under-specified. It does not earn its place as it provides no actionable information beyond the title.

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 that the tool has 5 parameters (2 required), no output schema, and moderate complexity, the description is grossly incomplete. It lacks any information about return values, error conditions, or usage examples, making it difficult for an agent to use 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 0%, meaning no parameter descriptions are provided. The description fails to explain any parameters, such as the format of 'color' (e.g., hex code) or the effect of optional fields like 'priority' or 'project_id'. The agent must rely solely on property names and types, which is insufficient.

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 label.' clearly states the verb and resource, but it is very minimal and does not distinguish this tool from sibling tools that also create other entities or even other label-related tools like gitlab_update_label. It lacks specificity about what type of label (project/group) is created.

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 given on when to use this tool versus alternatives, prerequisites, or context. The description provides no usage context.

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 adds no behavioral information beyond annotations. Annotations already indicate it's a non-read, non-destructive write operation. The description does not disclose traits like permission requirements, side effects (e.g., triggering CI), or result 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 extremely short (4 words) but lacks substance. Conciseness should not sacrifice completeness; here, it is under-specified.

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 high parameter count (13), absence of output schema, and no description coverage, the description is wholly inadequate. It does not explain the tool's purpose beyond the name, leaving agents with no useful context for correct 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 description provides no explanation of any of the 13 parameters. With 0% schema description coverage, the description should compensate but fails entirely, leaving agents reliant solely on parameter names.

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 merge request' clearly states the action (create) and resource (merge request). Among many sibling tools with similar names (e.g., gitlab_approve_merge_request, gitlab_merge_merge_request), it distinguishes the operation. However, it lacks any additional context about the nature of a merge request.

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. For example, it does not explain when to create versus update or merge a merge request, nor does it mention prerequisites like branch existence.

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?

Annotations indicate a write operation (readOnlyHint=false) and openWorldHint=true, but the description adds no behavioral context beyond the verb 'Add note'. It does not disclose side effects, permissions, or other traits that would help an agent assess risk.

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 that immediately conveys the core purpose. It is efficiently front-loaded without unnecessary 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 5 parameters and no output schema, the description is too brief. It lacks information on prerequisites, return values, error cases, or the relationship to other tools like gitlab_create_merge_request_note, 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?

With 0% schema description coverage, the description should compensate but only gives high-level context. It does not explain individual parameters (e.g., 'project_id' or 'created_at') nor provide format or usage details beyond what parameter names imply.

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 note') and the target resource ('existing MR discussion thread'), which effectively distinguishes it from creating a new thread. However, it does not explicitly differentiate from other note-creation tools like gitlab_create_merge_request_note, leaving some ambiguity.

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 the tool is for existing threads but provides no explicit guidance on when to use it vs. alternatives (e.g., gitlab_create_merge_request_thread or gitlab_create_merge_request_note). No exclusion criteria or usage context is given.

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?

Annotations readOnlyHint=false align with the write operation. However, the description adds no additional behavioral context (e.g., permission requirements, whether duplicate reactions are allowed, or rate limits).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, 15 words, front-loaded with the action. No unnecessary information.

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 add-reaction tool, the description is adequate but lacks details on success/error responses and how to differentiate from related tools like 'delete_merge_request_emoji_reaction'.

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 0%, but the description provides examples ('thumbsup, rocket, or eyes') for the 'name' parameter. It does not explain 'merge_request_iid' or 'project_id'.

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?

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?

Annotations indicate readOnlyHint=false and destructiveHint=false, which already convey mutability and non-destructiveness. The description adds only 'create' and 'top-level,' offering minimal additional behavioral context (e.g., no mention of whether notes are appended, permissions, or side effects).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise (six words), but this brevity sacrifices clarity and completeness. It does not front-load key information about parameters or behavior. A tool with three parameters should provide at least a brief explanation of each input.

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 simple tool structure (3 params, no output schema), the description is insufficient. It fails to describe what a merge request note is, how the 'top-level' distinction matters, or what the expected outcome is. Without parameter descriptions, the description 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?

With 0% schema description coverage, the description does not explain any of the three parameters (body, project_id, merge_request_iid). The user receives no guidance on what these parameters represent or how to format them beyond the schema constraints.

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 states 'Create a top-level MR note,' which specifies the verb and resource. However, it only marginally distinguishes from siblings like gitlab_create_issue_note or gitlab_create_draft_note, relying on the tool name for context. The phrase 'top-level' hints at differentiation from discussion notes, but is not explicit.

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 lacks any indication of when to use this tool versus alternatives (e.g., gitlab_create_issue_note, gitlab_create_draft_note, or gitlab_create_merge_request_discussion_note). There is no guidance on prerequisites or context.

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 adds that the tool targets notes and that discussion_id can be used for replies, complementing the annotations. However, it does not disclose permissions, idempotency, or other behavioral nuances beyond what annotations already convey.

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 concise and front-loaded with the action. However, it sacrifices necessary detail for brevity, especially regarding parameter meanings.

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 output schema and 5 parameters, the description is minimally adequate. It identifies the tool's purpose and hints at discussion_id usage but fails to fully cover required parameters or expected 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?

Given 4 parameters, no output schema, and a creation operation, the description is inadequate. It does not explain what is returned (e.g., the created tag object), error conditions, or that project_id is optional (defaulting to the current project). The agent lacks sufficient context to use this tool 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?

With 0% schema description coverage, the description should compensate by explaining parameters. However, only the 'ref' parameter is implicitly explained via 'from a branch, commit SHA, or another tag'. The 'tag_name', 'message', and 'project_id' parameters are not elaborated in the description, leaving the agent without key semantics.

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's purpose: creating a repository tag from a branch, commit SHA, or another tag. It uses a specific verb (Create) and resource (repository tag), distinguishing it well from sibling tools like gitlab_delete_tag, gitlab_get_tag, and gitlab_list_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 provides no guidance on when to use this tool versus alternatives (e.g., gitlab_create_branch, gitlab_create_release). There is no mention of prerequisites, typical use cases, or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint=false and destructiveHint=false; the description adds no extra behavioral context beyond stating the action, such as permissions, error handling, or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, clear sentence with no superfluous information, conveying the essential action efficiently.

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 having 5 parameters (3 required) and no output schema, the description is too sparse. It does not explain parameter formats (e.g., occurred_at), required fields' purpose, or the return value, 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?

Schema description coverage is 0%. The description only mentions 'optional tags' but fails to explain any of the other four parameters (note, occurred_at, incident_iid, project_id), leaving their semantics unclear.

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?

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, no prerequisites (e.g., incident must exist), and no conditions for when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate a write operation (readOnlyHint=false), non-destructive, non-idempotent. The description merely restates 'Create', adding no behavioral details such as required permissions, success conditions, or limits. With annotations present, the bar is lower, but the description still adds no value.

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, which is concise but lacks necessary detail. It could be longer to include useful information without becoming verbose.

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 no output schema, no parameter descriptions, and a minimal description, the tool definition is incomplete. An agent would lack sufficient context to use it correctly, especially without knowing parameter constraints or return 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 input schema has 4 parameters with 0% description coverage. The description does not explain any parameter semantics (e.g., what 'format' means, or that 'project_id' is for selecting the project). This is a critical gap for correct invocation.

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 (wiki page). However, it does not differentiate from the sibling tool 'gitlab_create_group_wiki_page', which likely creates a wiki page for a group vs a project. This lack of distinction prevents a top 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?

No guidance is provided on when to use this tool versus alternatives like 'gitlab_create_group_wiki_page' or 'gitlab_update_wiki_page'. There is no context about prerequisites or typical use cases.

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?

Annotations already indicate a write operation (readOnlyHint=false) and non-idempotent behavior. Description adds no extra context about side effects, permissions, or potential failure modes.

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, which is concise but lacks structure. It front-loads the purpose but omits important details about usage and parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

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 compared to alternatives like gitlab_create_issue or gitlab_create_merge_request. The description only lists types without context on selection criteria.

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 is minimal beyond what annotations already provide. It confirms a write operation ('Add') but does not clarify idempotency (e.g., duplicate reactions), required permissions, or side effects. Annotations already signal non-readOnly, non-idempotent, non-destructive, so the description adds little behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise (one sentence) and front-loaded with the action and examples. However, it sacrifices necessary detail for brevity, making it merely adequate rather than exemplary.

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 three parameters, no output schema, and a single-sentence description, the definition lacks completeness. It does not describe return values, error conditions, or how the tool fits into the workflow of managing work item reactions.

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 0%, and the description only indirectly explains one parameter ('name') by providing examples. It does not clarify the 'iid' (work item internal ID) or 'project_id' (optional project scope). The agent cannot infer complete parameter meaning from the description alone.

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 explicitly states the action 'Add an emoji reaction' and the resource 'work item', with concrete examples like 'thumbsup, rocket, or eyes'. It clearly distinguishes from sibling tools for issues, merge requests, notes, etc., as the target is specifically a work 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?

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 recommends a pre-check using gitlab_list_merge_request_discussions, which guides the agent to first retrieve discussion IDs. It does not explicitly state when not to use the tool or contrast with alternatives, but the suggestion provides practical usage context.

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?

Adds value beyond annotations by describing the action as 'permanently' and 'irreversible', aligning with destructiveHint=true. No contradiction; annotations already flag destructiveness. Does not detail permissions or side effects, but the core behavioral trait is covered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, directly stating purpose and a usage hint. No redundant words, well-structured and easy to parse.

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?

Adequate for a simple destructive tool but missing explanation of project_id and potential error conditions. Given no output schema and open world hint, more context on required parameters would improve 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?

With 0% schema description coverage, the description only mentions merge_request_iid and award_id as required, but omits project_id entirely. It gives no explanation of parameter roles or formats beyond naming. The pre-check recommendation adds slight context for award_id, but incomplete.

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 deletes an emoji reaction from a merge request permanently, using verb 'delete' and specific resource 'emoji reaction from a merge request'. It distinguishes from siblings by specifying merge request, avoiding confusion with issue or work item emoji deletions.

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?

Provides a recommended pre-check using gitlab_list_merge_request_emoji_reactions to obtain the award_id. Gives context for prerequisite data. However, it does not explicitly state when not to use this tool or mention alternatives.

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?

Discloses permanent deletion and irreversibility, aligning with destructiveHint annotation. Adds context beyond annotations about required parameters and pre-checks.

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 tight sentences, front-loaded with action and irreversibility, then requirements and guidance. No 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?

Covers essential behavioral and usage details for a simple delete tool. Lacks error handling or project_id explanation, but sufficient for typical 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?

Mentions two required parameters but ignores optional project_id. With 0% schema description coverage, description should explain all parameters; missing project_id leaves ambiguity.

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?

Specifically states 'Delete a top-level MR note permanently', clearly identifying the verb (delete) and resource (top-level MR note). Distinguishes from sibling tools like gitlab_delete_merge_request_discussion_note.

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?

Explains irreversibility, required parameters (merge_request_iid and note_id), and recommends pre-check tools. Could explicitly state when not to use, but provides good context.

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?

Annotations indicate destructiveHint=true, and the description adds 'Irreversible for that reaction', aligning with annotations. No contradictions. Additional context about permanence and required IDs is provided.

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 and key trait (permanence), second lists requirements and recommendation. No fluff, front-loaded.

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; description does not mention return values, error handling, or permissions. For a destructive 5-parameter tool, it could elaborate on optional params and outcomes. However, it covers core usage with pre-check.

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 0%. The description names three required parameters and hints at their role, but does not describe optional parameters (project_id, discussion_id) or provide detailed format/semantics 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 'Delete', the resource 'emoji reaction from a merge request note', and emphasizes permanence. It distinguishes from sibling tools like create or list reactions.

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?

Explicitly lists required parameters (merge_request_iid, note_id, award_id) and recommends a pre-check with gitlab_list_merge_request_note_emoji_reactions. Provides clear context for when to use this tool, though does not explicitly state when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
