jenkins_replay_build

Replay a pipeline build with an original or modified Groovy script. Rerun builds to test changes without creating a new job.

Instructions

Replay/rerun a pipeline build, optionally with a modified pipeline script

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
jobNameYesName of the Jenkins job
instanceNoJenkins instance name (optional — defaults to first configured instance)
mainScriptNoOptional Groovy pipeline script to use instead of the original. When omitted, the original build script is replayed unchanged.
buildNumberYesBuild number to replay
Behavior3/5

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

Annotations indicate non-readonly, non-idempotent, non-destructive. The description adds no further behavioral details, such as whether replaying modifies the original build or triggers new downstream jobs.

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?

Single sentence, clearly front-loaded with the core action. No wasted words.

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?

Covers the core functionality but lacks mention of return values (e.g., new build number) or potential side effects. However, given the action is straightforward, it is largely sufficient.

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 minimal value beyond summarizing the mainScript parameter. It does not explain how the optional instance parameter affects behavior.

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 the tool replays/reruns a pipeline build, optionally with a modified script. It distinguishes from siblings like jenkins_trigger_build by specifically targeting replaying an existing build.

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?

No explicit guidance on when to use this tool vs alternatives. While the optional modified script is mentioned, there is no comparison with other build-related tools like jenkins_trigger_build or jenkins_stop_build.

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