list_pipelines

Read-only

Retrieve recent pipelines for a GitLab project. Filter results by branch or status to monitor specific pipeline runs.

Instructions

List recent pipelines for a project. Filter by branch (ref) or status (running, pending, success, failed, canceled).

Tool call template

TDQS

A4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, so the description needs minimal behavioral disclosure. It adds filter details but does not explain ordering (e.g., most recent first) or pagination behavior. This is acceptable but not exhaustive.

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

Conciseness5/5

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

Two concise sentences, front-loaded with the core action and followed by filter options. No unnecessary words or redundancy.

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

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a listing tool with simple parameters and readOnly annotation, the description is fairly complete. It covers the resource, filters, and basic behavior. However, the term 'recent' is vague and pagination details are missing, leaving minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the description adds marginal value beyond the schema. It mentions 'filter by branch (ref) or status' and lists some status values, but does not provide additional parameter details like format or constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'list recent pipelines for a project', using verb 'list' and specifying the resource 'pipelines'. It distinguishes from sibling tools like get_pipeline (single pipeline) and cancel_pipeline (action), 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.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for listing pipelines with optional filters, but does not explicitly exclude alternatives like get_pipeline for single pipelines or other list tools. The context is clear but lacks explicit 'when not to use' guidance.

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