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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds genuine value by naming the returned fields and the download link and by giving the endpoint path, but it says nothing about pagination, result limits, or ordering for a list operation.

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?

A single tight sentence plus the endpoint, front-loaded with the resource and the returned fields. Nothing is wasted, though it is arguably too terse for a list tool.

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?

No output schema exists, and the description partially compensates by listing the returned fields (name, locale, links). Combined with a fully documented input schema and clear read-only annotations, an agent has enough to call it correctly; only pagination/result-size behavior is missing.

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 five parameters (including the branch default/422 behavior and the locale_in_file_name enum) are fully documented in the schema. The description adds no parameter semantics beyond embedding project_url in the endpoint path, so the baseline 3 applies.

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?

States a specific verb (List) and resource (a project's resource files) and enumerates the returned fields, making it distinct from lingohub_list_projects and lingohub_list_context_images. It stops short of explicitly naming a sibling for differentiation, so a 4 rather than 5.

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?

No indication of when to use this versus alternatives such as lingohub_get_project or lingohub_list_projects, and no stated prerequisites or exclusions. The agent must infer the calling context from the name alone.

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