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

No annotations are provided, so the description must carry the full burden. The verb 'Fetch' clearly implies a read-only operation, and the description lists what is returned. However, it does not disclose additional behavioral traits such as error behavior for invalid UUIDs, authorization requirements, rate limits, or pagination. For a simple read tool this is adequate, but not rich.

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, tightly written sentence front-loads the verb and resource, then lists inclusions in a natural order. Every word earns its place; there is no fluff, repetition, or irrelevant detail.

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 tool with two parameters and an output schema, the description adequately covers the primary behavior. It does not need to describe return values because an output schema exists. Minor omissions like error handling or performance characteristics are not critical for correct invocation, and the sibling list provides enough surrounding context for tool selection.

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% for both parameters, so the baseline is 3. The description adds value by specifying exactly what is always returned (sections, latest status, attached files) and that tasks are optional, reinforcing the role of include_items. This context goes beyond the schema's terse 'Include the project's tasks (board view)'.

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 begins with a specific verb 'Fetch' and a clear resource 'a project', then enumerates the full payload: sections, latest status, attached files, and optionally tasks. This distinguishes it from project_list (which lists projects) and work_get (single work item) without ambiguity.

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 description clearly conveys the tool's scope: it returns a project with its related entities, so an agent knows to select it when needing project detail. It also hints at the include_items toggle by saying 'optionally its tasks', but it does not explicitly mention alternatives like project_list or exclusions (e.g., when to prefer a lighter list).

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