List badges

list_badges
Read-onlyIdempotent

Retrieve status badge URLs for each project tag, including variants that report grace periods separately.

Instructions

Lists the status badge URLs of the project, one entry per tag plus "*" for the project as a whole. The plain variants treat a check in its grace period as up; the ones suffixed 3 report up, late and down separately.

TDQS

A3.8/5.0
Behavior3/5

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

The annotations already provide readOnly, idempotent, and non-destructive hints, which cover the core behavioral expectations. The description adds no extra side-effect or rate-limit information but does not contradict the annotations, so a neutral score is appropriate.

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?

The description is two sentences, concise, and directly to the point. It includes necessary detail about the two variants without any extraneous text 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?

No output schema is provided, so the description must convey the expected return. It explains the two types of URLs and their semantics, which gives a solid understanding of the output. The exact structure (e.g., array of strings) is not specified, but it is reasonably implied.

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

Parameters4/5

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

The tool has zero parameters, and the schema coverage is therefore 100% (vacuously). With no parameters to document, the description does not need to add parameter-level detail, so the baseline score of 4 is given.

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 resource (status badge URLs) and the specific scope (one per tag plus project-wide). It also explains the distinction between plain and '3'-suffixed variants, which differentiates it from other list tools in the sibling set.

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?

The description does not provide explicit guidance on when to use this tool versus alternatives, such as list_checks or list_pings. It describes what the tool does but not the conditions that would make it the preferred choice.

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