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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds genuine value by disclosing the auth scoping rule (results are limited to what the token can see) and the shape of returned records, but says nothing about rate limits, ordering, or total-count behavior.

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?

One sentence plus the endpoint, front-loaded with the verb and scope, and the field list earns its place by previewing the payload. No filler, though the bare endpoint citation is only marginally useful.

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?

There is no output schema, but the description compensates by enumerating the returned fields (name, slug, website, settings) and the access-control/review-workflow content. Pagination is fully handled by the schema, so an agent has enough to call this correctly.

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% and both parameters (page, page_size) are fully documented in the schema with defaults and bounds, so the baseline of 3 applies. The description adds no pagination syntax or semantics beyond what the schema already states.

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?

Specific verb (list) plus resource (projects) and an explicit scope qualifier ("visible to this token"), with the returned fields enumerated. It distinguishes itself from weblate_get_project by being a collection listing, though it never names that sibling explicitly.

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 when-to-use guidance and no exclusions: nothing tells the agent to prefer weblate_get_project for a single project or weblate_list_project_languages for nested language data. The pagination continuation hint lives in the schema, not the description.

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