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

Annotations already cover the safety profile (readOnlyHint=true, destructiveHint=false, openWorldHint=true), so the description's job is to add context. It does so usefully by naming the resources returned — including the project_locales field name — and giving the HTTP route, which tells the agent this is a direct single-resource fetch with no filtering or pagination.

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?

Two sentences: the payload contents first, the endpoint second. No filler, no redundancy with the title (which merely says 'Get project').

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 enumeration of returned fields is doing necessary work and largely covers the return contract; the endpoint path disambiguates from status/export tools. Minor gap: nothing on behavior for a missing or inaccessible project slug.

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 are documented with examples and a pointer back to list_projects as their source. The description adds nothing beyond naming project_url in the path template, so 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+resource ('One project') and enumerates exactly what a project contains (title, description, owner email, project_locales, timestamps, links), plus the REST endpoint. This clearly separates it from lingohub_list_projects, 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?

Usage is implied by 'One project' versus the plural list tool and by the required project_url/workspace_url pair, but there is no explicit 'use this when you have a slug from list_projects' statement or any exclusion. An agent can infer the case but must do the work itself.

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