Pipeline Jobs

get_pipeline_jobs
Read-onlyIdempotent

Retrieve jobs for a specific GitLab pipeline to inspect status, stage, duration, and retry or cancel details.

Instructions

Get jobs for a specific pipeline, including status, stage, duration, and retry/cancel info

Input Schema

NameRequiredDescriptionDefault
afterNoPagination cursor. To fetch the next page, pass the previous response pageInfo.endCursor here and repeat until pageInfo.hasNextPage is false. Paginating this way is the reliable path to complete results and accurate totals.
firstNoNumber of jobs to retrieve
fetchAllNoFetch multiple pages in one call, up to "first" items total (max 100) — NOT exhaustive. For complete results or accurate counts, leave this false and paginate via after (pageInfo.endCursor).
pipelineIidYesPipeline IID
projectPathYesFull path of the project (e.g., "group/project-name")
userCredentialsNoYour GitLab credentials (optional — falls back to the configured env token if not provided)

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered structurally. The description adds that returned job records carry status, stage, duration and retry/cancel info, which is useful, but it stays silent on ordering, pagination behavior, and auth fallback — though the schema covers the latter two.

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?

A single tight sentence with the core operation front-loaded and the return contents tacked on compactly. Nothing wasted, nothing buried.

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?

With no output schema, the brief enumeration of returned job fields is genuinely valuable. The main gap is that pagination semantics — the schema's most important behavioral nuance — aren't echoed in the description, but the schema spells it out thoroughly.

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 description coverage is 100%, including the pagination/vs-fetchAll tradeoff and credential fallback, so the baseline is 3. The description contributes no additional parameter meaning beyond what the schema already states.

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

Purpose4/5

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

Specific verb+resource: 'Get jobs for a specific pipeline', plus an enumeration of what the payload contains (status, stage, duration, retry/cancel). It doesn't distinguish itself from pipeline-related siblings like manage_pipeline or get_merge_request_pipelines, but the resource is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

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

Usage is implied — you call it when you have a projectPath and pipelineIid and want that pipeline's jobs. There is no explicit when-to-use/when-not, no mention of pagination strategy, and no routing away from manage_pipeline or get_merge_request_pipelines.

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