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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds real value by disclosing the payload shape — that the response aggregates settings, site-analysis status, a video sub-list with job state, and any open quote — which tells the agent this is a heavy composite fetch, not a thin record read. It is silent on missing-project behavior, but that is a minor gap given the annotation coverage.

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 sentence with zero filler, and the returned-content list is front-loaded. It is telegraphic (no verb), which costs some readability but not economy.

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 well by enumerating the returned fields and their nesting concept (videos each with status and latest job). The main omissions are error behavior for a nonexistent or unauthorized project, which an agent doing a direct id lookup would benefit from.

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?

Only one parameter exists and the schema already supplies type, uuid format, and a strict pattern, so parameter meaning is largely carried by structured data despite 0% description coverage. The description never mentions project_id or the uuid requirement, adding nothing beyond the schema — 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?

The description names a single resource (one project) and enumerates exactly what comes back: settings, site-analysis status, videos with status and latest job, open quote. That is specific enough to separate it from list_projects and get_video, though it is written as a noun fragment rather than an explicit verb+resource statement.

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?

There is no statement of when to call this versus list_projects (to discover an id) or get_video (for a single video). The phrase 'One project' weakly implies singular lookup, but there are no conditions, prerequisites, or named alternatives.

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