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

Annotations already establish the safe, read-only, open-world profile, so the bar is lower. The description still adds genuine operational context: repository URLs have embedded credentials stripped, and the returned fields include repository, file mask, source language and status flags. Pagination behavior, however, is left entirely to the schema.

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

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

Three short sentences plus an endpoint citation; the core purpose and the scoping hint are front-loaded with no filler. The explicit GET path is slightly technical overhead but is compact and useful for API-oriented agents.

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

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

With no output schema, the description compensates by enumerating the notable returned fields and the credential-stripping safety behavior. Combined with the fully-documented input schema, an agent has enough to call this correctly; only pagination semantics are left implicit in the schema.

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

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

Schema description coverage is 100%, so all three parameters (page, project, page_size) are already documented in the schema, including pagination chaining via next_page. The description only echoes the project filter ('Give a project to list only its components') and adds no syntax or format detail beyond the schema.

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

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

The description states a specific verb (List) and resource (translation components) and even defines the resource parenthetically as 'one translatable file set in a repository'. It also clarifies the scoping behavior ('Give a project to list only its components'), which cleanly separates it from weblate_list_projects, weblate_list_translations and weblate_list_units.

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

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

It implies usage by explaining that supplying a project narrows the result set, and it cites the two backing endpoints. However, it never states when to prefer this tool over weblate_get_component (single component) or weblate_list_projects, so the routing guidance remains implied rather than explicit.

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