Available Tools
9 toolscreate_branchB
Create a new branch in a GitLab project
| Name | Required | Description | Default |
|---|---|---|---|
| ref | No | Source branch/commit for new branch | |
| branch | Yes | Name for the new branch | |
| project_id | Yes | Project ID or URL-encoded path |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and description omits behavioral details like error handling on duplicate branch, permission requirements, or whether ref is optional.
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 with key info, but lacks structure for complex details.
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 and no annotations, description is too brief. Does not mention important context like branch naming rules or default 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?
Schema covers 100% of parameters with descriptions. Description adds no extra meaning beyond what 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?
Description clearly states action (Create), resource (branch), and context (GitLab project). It effectively distinguishes from sibling tools as no other tool creates branches.
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 or exclusions provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
create_issueB
Create a new issue in a GitLab project
| Name | Required | Description | Default |
|---|---|---|---|
| title | Yes | Issue title | |
| labels | No | Array of label names | |
| project_id | Yes | Project ID or URL-encoded path | |
| description | No | Issue description | |
| assignee_ids | No | Array of user IDs to assign | |
| milestone_id | No | Milestone ID to assign |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility for disclosing behavioral traits. It only states the basic action, omitting side effects (e.g., audit trail, notifications), authorization needs, rate limits, or what occurs on success/failure. This is insufficient for an agent to use the tool safely.
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 fluff. It conveys the core purpose efficiently. However, it could be slightly expanded to include key usage hints without losing conciseness.
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 6 parameters (2 required) and no output schema, the description fails to provide enough context for complete understanding. It does not explain the relationship between parameters or common usage patterns, leaving the agent to infer from the schema 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?
The input schema covers all 6 parameters with descriptions, achieving 100% schema coverage. The description adds no new meaning beyond the schema, so a baseline score of 3 is appropriate. No parameter information is missing from the structured data.
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 issue in a GitLab project'). It effectively distinguishes from sibling tools like create_branch or create_merge_request, leaving no ambiguity about what this tool does.
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., create_merge_request). It does not mention any prerequisites, such as required permissions or project existence, and offers no example scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
create_merge_requestB
Create a new merge request in a GitLab project
| Name | Required | Description | Default |
|---|---|---|---|
| draft | No | Create as draft merge request | |
| title | Yes | Merge request title | |
| project_id | Yes | Project ID or URL-encoded path | |
| description | No | Merge request description | |
| source_branch | Yes | Branch containing changes | |
| target_branch | Yes | Branch to merge into | |
| allow_collaboration | No | Allow commits from upstream members |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description is minimal and does not disclose any behavioral traits beyond the basic creation. No mention of permissions, side effects, or what happens on success/failure. With no annotations, description carries full burden but fails to provide insights.
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 with no unnecessary words. However, it could be considered under-specified but that is more about completeness than conciseness.
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 7 parameters and no output schema, the description is insufficient. It does not explain return values, error conditions, or any additional context needed for proper 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 has 100% description coverage, so the schema already documents all 7 parameters. 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?
Description clearly states the action 'Create' and resource 'merge request' in a specific context 'GitLab project'. It distinguishes from siblings like create_branch and create_issue.
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 like create_branch or create_issue. No context about prerequisites 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.
create_or_update_fileC
Create or update a single file in a GitLab project
| Name | Required | Description | Default |
|---|---|---|---|
| branch | Yes | Branch to create/update the file in | |
| content | Yes | Content of the file | |
| file_path | Yes | Path where to create/update the file | |
| project_id | Yes | Project ID or URL-encoded path | |
| previous_path | No | Path of the file to move/rename | |
| commit_message | Yes | Commit message |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description alone must disclose behavioral traits. It only states the action ('create or update') but does not mention side effects, required permissions, idempotency, or what happens if the file already exists or not. 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 concise sentence that immediately conveys the purpose. It is front-loaded and efficient, though it could benefit from slight expansion.
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 6 parameters, no output schema, and no annotations, the description is too brief. It omits details about rename behavior via 'previous_path', error conditions, size limits, and typical usage flows. Incomplete for a complex mutation 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?
Schema coverage is 100%, meaning all parameters have descriptions in the schema. The description adds no extra meaning beyond what the schema already provides, so 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?
Description clearly states the verb ('Create or update') and resource ('a single file in a GitLab project'). It is specific enough to distinguish from most siblings, though not explicitly from 'push_files' which may have overlapping functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'push_files' or 'get_file_contents'. No when-not-to-use or prerequisite information is included.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
create_repositoryC
Create a new GitLab project
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes | Repository name | |
| visibility | No | Repository visibility level | |
| description | No | Repository description | |
| initialize_with_readme | No | Initialize with README.md |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It only says what the tool does, but does not disclose side effects, authentication needs, or output behavior. For a creation tool, more detail is expected.
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 5 words. It is concise but too minimal; it could benefit from a bit more context without losing efficiency.
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 or annotations, the description should explain return values or what happens after creation. It does not, leaving agents without critical 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?
Input schema has 100% coverage with descriptions for all 4 parameters. The description adds no extra meaning beyond the schema, meeting the baseline of 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 GitLab project' clearly states the verb (create) and resource (repository/project). It distinguishes from siblings like create_branch or create_issue, but does not explicitly differentiate.
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. Does not mention prerequisites, use cases, or exclusions, leaving agents to infer.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
fork_repositoryB
Fork a GitLab project to your account or specified namespace
| Name | Required | Description | Default |
|---|---|---|---|
| namespace | No | Namespace to fork to (full path) | |
| project_id | Yes | Project ID or URL-encoded path |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description is the sole source for behavioral traits. It only describes the basic action without disclosing potential side effects, permissions, visibility settings, or confirmation of success.
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 concise and direct. However, it could be restructured to front-load more crucial information or be slightly expanded without losing conciseness.
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 a simple tool with 2 parameters and no output schema, the description lacks details about what happens after forking (e.g., new repository creation, visibility), 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 covers both parameters with descriptions (100% coverage), so the description adds no extra meaning. Baseline score of 3 applies as the schema is self-sufficient.
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 (Fork) and resource (GitLab project) with explicit destination options (your account or specified namespace). It is distinct from siblings like create_repository or create_branch.
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. There is no mention of prerequisites, exclusions, or comparison to sibling tools like create_repository.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_file_contentsB
Get the contents of a file or directory from a GitLab project
| Name | Required | Description | Default |
|---|---|---|---|
| ref | No | Branch/tag/commit to get contents from | |
| file_path | Yes | Path to the file or directory | |
| project_id | Yes | Project ID or URL-encoded path |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure, but it only states 'Get', implying a read operation without confirming safety, authentication needs, or potential 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?
Single sentence, 11 words, no waste. Efficiently conveys the core purpose, though could be slightly more informative without losing conciseness.
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 exists, so the description should explain return value format or behavior (e.g., raw text, JSON, pagination). It only says 'get contents', leaving the agent uninformed about what to expect.
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 baseline is 3. The description adds no additional meaning to the parameters beyond what the schema already 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 tool gets 'contents of a file or directory from a GitLab project', using a specific verb and resource. It distinguishes from sibling tools which are all about creating or searching, not retrieving contents.
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, no prerequisites or exclusions provided. The description lacks any contextual cues for appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
push_filesC
Push multiple files to a GitLab project in a single commit
| Name | Required | Description | Default |
|---|---|---|---|
| files | Yes | Array of files to push | |
| branch | Yes | Branch to push to | |
| project_id | Yes | Project ID or URL-encoded path | |
| commit_message | Yes | Commit message |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It only mentions that the push is in a single commit, but lacks details on whether files can be created or updated, what happens on merge conflicts, permission requirements, or rollback behavior. 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 sentence with no wasteful words. It is front-loaded with the core action and 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 no output schema and no annotations, the description should provide more context about prerequisites, success conditions, and failure modes. It lacks completeness for a tool that modifies project files.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with all 4 parameters described in the schema. The tool description adds no extra semantic meaning beyond 'push multiple files' and 'single commit'. 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's action: pushing multiple files to a GitLab project in a single commit. It uses a specific verb ('push') and resource ('GitLab project'), and implicitly distinguishes from sibling tools like create_or_update_file which handle single files.
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 create_or_update_file or create_branch. The description does not mention prerequisites like branch existence or file path constraints.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
search_repositoriesB
Search for GitLab projects
| Name | Required | Description | Default |
|---|---|---|---|
| page | No | Page number for pagination (default: 1) | |
| search | Yes | Search query | |
| per_page | No | Number of results per page (default: 20) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description does not disclose behavioral traits such as read-only nature, rate limits, or response format. It only states 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 is concise, but it lacks structure or front-loading of key information. It serves its purpose without excess.
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 search tool with three parameters and no output schema, the description is minimally adequate. It does not explain return values or search behavior beyond the basic verb.
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 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?
Description says 'Search for GitLab projects' which is a specific verb and resource. It clearly distinguishes from sibling tools which are about creation, branching, and file 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 guidance on when to use this tool versus alternatives. The description provides no context for when searching is appropriate compared to other actions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Each tool targets a distinct resource or action (branch, issue, merge request, file, repository, fork, search) with no overlapping purposes.
All tool names follow a consistent verb_noun pattern (e.g., create_branch, get_file_contents), with only 'create_or_update_file' being slightly longer but still consistent.
9 tools is well-scoped for a GitLab server, covering core operations without being excessive or insufficient.
Covers essential create/read operations but lacks explicit update/delete for issues, merge requests, and branches, which agents may need to work around.
