B3/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only the default limit of 3 — which is already in the schema — and says nothing about ordering ('latest' by what field), pagination, or whether results span branches when no branch filter is given.

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

Conciseness4/5

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

A single front-loaded sentence with no filler — the core purpose arrives immediately. It is lean to the point of under-specification, but nothing in it is wasted or buried.

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

Completeness3/5

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

An output schema exists, so return shape needn't be described, and annotations cover the read-only nature. However, for a five-parameter tool with a required project argument and a namespace qualifier, the description says nothing about parameter interplay or how 'latest' is ordered, which is the main informational gap an agent would hit.

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

Parameters2/5

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

Five parameters at 60% schema coverage; the description repeats only the limit default already present in the schema. It does not explain the required project parameter's accepted forms, how namespace interacts with project, or what branch filtering does to the 'latest' semantics, leaving the undocumented namespace parameter with no explanation anywhere.

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?

States a specific verb and resource — returns the status of the latest pipeline runs — with the default count noted. It is clear what the tool returns, but it never distinguishes itself from close siblings like gl_pipeline_get, gl_pipeline_diagnose, or bb_pipelines_latest, so the agent must infer the boundary.

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

Usage Guidelines2/5

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

There is no when-to-use / when-not-to-use guidance and no mention of the alternatives (gl_pipeline_get for a specific pipeline, gl_pipeline_diagnose for failures). The agent is left to infer that this is the list-recent entry point rather than the single-pipeline or diagnostic tools.

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