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

Annotations already mark this as readOnlyHint=true, and the description reinforces this with GET semantics. It adds useful behavioral context by saying the response includes region, cluster, and associated services/jobs/addons, going beyond a bare 'get'. No destructive or hidden side effects are suggested.

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 with no filler: the first gives the action and scope, the second gives the endpoint. The behavioral description is front-loaded and every clause earns its place.

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 simple read-only detail tool, the description plus schema and annotations are sufficient: the target resource, ID source, and general response contents are covered. With no output schema, the response-content hint is valuable, though error/not-found behavior is not mentioned.

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?

The single projectId parameter is fully documented in the schema, including its source from northflank_list_projects, so schema description coverage is 100%. The description's endpoint template adds no further parameter meaning beyond what the schema already provides. Baseline 3 is appropriate.

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 states an explicit verb and resource: 'Get details of a single project'. It also enumerates the included scope (region, cluster, associated services/jobs/addons) and provides the endpoint. This clearly distinguishes it from sibling tools like northflank_get_service or northflank_list_projects.

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?

The tool is clearly scoped to fetching one project by ID, and the schema further says projectId comes from northflank_list_projects, implying the intended workflow. It does not explicitly name alternatives or state when not to use it, but the resource-specific description makes the usage context obvious.

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