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

Annotations declare readOnlyHint=false with destructiveHint=false, which is ambiguous on its own, and the description usefully resolves the ambiguity by explaining the site runs client-side so there is nothing to start or wait for. It adds real behavioral value beyond annotations by naming the returned shareable link, though it does not cover failure cases like an invalid projectId.

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 short sentences, front-loaded with the action and its result. The second sentence earns its place by preempting a wait/poll behavior, though it restates the 'ready at once' idea twice.

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?

For a one-parameter tool with no output schema, the description covers the action and the returned artifact (Xodia link), which is what an agent needs. It stops short of stating idempotency or error behavior, a minor gap given the tool's simplicity.

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 coverage is 100% and the single projectId parameter is already documented as coming from list_projects, so the schema does the work. The description adds no further meaning about the parameter, which is the expected baseline.

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 and resource ('Opens the project') and names the concrete result ('returns the Xodia link'), which distinguishes it from retrieval siblings like get_project or list_projects. It never explicitly says how it differs from those siblings, keeping it short of a 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?

Usage is only implied — an agent can infer you call this when a project must become workable, but there is no explicit when-to-use, no exclusion of alternatives such as get_project, and no guidance on whether it should be called repeatedly.

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